Research background. Watermelon rind, a by-product of watermelon juice processing, contains high amounts of dietary fiber and phenolics with antioxidant capacity. The use of agro-industrial by-products would improve the economic benefits as well as reduce the environmental emissions. The goal of this research was to examine the impacts of particle size of watermelon rind powder on the quality of high-fiber pasta.Experiment approach. Three samples of watermelon rind powder passed through three sieves with aperture sizes of 400, 210, and 149 μm were determined for their nutritional, physical and physicochemical quality. Wheat durum semolina and watermelon rind powder (90:10 by mass) were then mixed and used to make pasta. Nutritional, textural, and cooking quality, sensory acceptability, in vitro glycemic index, and antioxidant bioaccessibility of high-fiber pasta added with watermelon rind powder with different particle size means were evaluated and compared.Results and conclusions. When the sieve aperture size was reduced from 400 to 149 µm, the soluble dietary fiber and total phenolic contents of watermelon rind powder were enhanced by 35 and 15%, respectively while its insoluble dietary fiber content was decreased by 21%. Decrease in sieve aperture size from 410 to 149 µm for watermelon rind powder reduced phenolic bioaccessibility of the fortified pasta from 63 to 57% but enhanced its predicted glycemic index from 50 to 69; such decrease also lowered the pasta hardness by 13% but improved its elongation rate and tensile strength by 13 and 40%, respectively. The finer the watermelon rind powder particles, the longer the optimal cooking time, the greater the water absorption index, and the less the cooking loss of the supplemented pasta. Consumers did not notice any significant difference in the overall acceptability among all pasta samples.Novelty and scientific contribution. Particle size of watermelon rind powder had great impacts on nutritional, textural and cooking quality of the fortified pasta. Particularly, the predicted glycemic index and antioxidant bioaccessibility of high-fiber pasta were significantly affected by the particle size of dietary fiber material used in the recipe.
研究背景。西瓜皮是西瓜汁加工的副产品,含有大量膳食纤维和具有抗氧化能力的酚类物质。利用农工副产品可以提高经济效益,减少环境排放。本研究的目的是考察西瓜皮粉的粒度对高纤维面食质量的影响。实验方法:三种西瓜皮粉样品分别通过孔径为 400、210 和 149 μm 的三个筛子,测定其营养、物理和理化质量。然后将小麦硬质小麦粉和西瓜皮粉(质量比为 90:10)混合并用于制作意大利面。对添加了不同粒度的西瓜皮粉的高纤维面食的营养、质地和烹饪质量、感官可接受性、体外血糖生成指数和抗氧化剂生物利用率进行了评估和比较。当筛孔尺寸从 400 微米减小到 149 微米时,西瓜皮粉的可溶性膳食纤维和总酚含量分别提高了 35%和 15%,而不溶性膳食纤维含量则降低了 21%。将西瓜皮粉的筛孔尺寸从 410 微米减小到 149 微米后,强化面食的酚类生物可及性从 63% 降至 57%,但其预测血糖生成指数从 50 升至 69;筛孔尺寸的减小还使面食硬度降低了 13%,但其伸长率和拉伸强度分别提高了 13% 和 40%。西瓜皮粉颗粒越细,最佳烹饪时间越长,吸水指数越高,添加西瓜皮粉的面食的烹饪损失越小。消费者对所有面食样品的总体接受度均无明显差异。西瓜皮粉的粒度对强化面食的营养、质地和烹饪质量有很大影响。特别是,配方中使用的膳食纤维材料的粒度对高纤维意大利面的预测血糖生成指数和抗氧化剂生物利用率有显著影响。

Research background. The current changes in the global economy, characterised by the climate crisis and the economic and health impact of the COVID-19 pandemic, have led to a significant demand for medicinal herbs. This trend is expected to increase significantly by 2050. In this study, we investigated the biopotential of aqueous infusions of four medicinal plants: Calendula officinalis, Chelidonium majus, Teucrium chamaedrys, and Alchemilla vulgaris. Experimental approach. The flavonoid analysis of the aqueous infusions of selected plants was carried out using the RP-HPLC technique. The antiproliferative activity of the prepared aqueous plant infusions was analysed against three human cancer cell lines (MDA-MD-231, T24, and A549), while the antioxidant potential was measured using three antioxidant methods (DPPH, FRAP, and Rancimat assay). Results and conclusions. T. chamaedrys had highest total phenolics (2061.20±42.36 mg GAE/L), free radical scavenging activity (IC50 = 1.9 mg/mL) and ferrous reducing antioxidant power (9797.82±26.96 mg FeCl2/L). At a concentration of 1 mg/mL, the antiproliferation of T24 by C. majus was as high as 96 %, and of MDA-MD-231 cells by A. vulgaris 75 % after 72 h. After principal component analysis, T. chamaedrys and C. majus were grouped together. Quercetin-glucoside and antioxidant capacity (DPPH) contributed the most to separate these infusions from the other two. Novelty and scientific contribution. This study represents a comparative analysis of the biopotential of four medicinal plants. A new RP-HPLC method was developed to separate the flavonoids in the herbal infusions. This is the first report on kaempferol-3-O-rutinoside in C. officinalis, and isorhamnetin-3-O-rutinoside in A. vulgaris aqueous infusion. For the first time, C. majus was shown to contribute to the oxidative stability of edible oil. Furthermore, this is the first comparative study on the antiproliferative activity of selected medicinal plants against the cell lines MDA-MD-231, T24 and A549.
研究背景。当前全球经济的变化以气候危机和 COVID-19 大流行病对经济和健康的影响为特征,导致了对药草的大量需求。预计到 2050 年,这一趋势将大幅增加。在这项研究中,我们调查了四种药用植物水溶液的生物潜力:实验方法。实验方法。采用 RP-HPLC 技术对所选植物的水溶液进行黄酮类化合物分析。分析了制备的植物水溶液对三种人类癌细胞株(MDA-MD-231、T24 和 A549)的抗增殖活性,并使用三种抗氧化方法(DPPH、FRAP 和 Rancimat 分析法)测量了抗氧化潜力。结果和结论T. chamaedrys 具有最高的总酚(2061.20±42.36 mg GAE/L)、自由基清除活性(IC50 = 1.9 mg/mL)和亚铁还原抗氧化能力(9797.82±26.96 mg FeCl2/L)。在 1 mg/mL 的浓度下,72 小时后,C. majus 对 T24 细胞的抗增殖率高达 96%,A. vulgaris 对 MDA-MD-231 细胞的抗增殖率为 75%。槲皮素-葡萄糖苷和抗氧化能力(DPPH)是将这些输液与其他两种输液区分开来的最大因素。新颖性和科学贡献。本研究对四种药用植物的生物潜力进行了比较分析。研究人员开发了一种新的 RP-HPLC 方法,用于分离草药浸剂中的黄酮类化合物。这是首次报道山奈酚-3-O-芸香糖苷和异鼠李素-3-O-芸香糖苷。研究首次表明,大叶女贞有助于提高食用油的氧化稳定性。此外,这是首次比较研究选定药用植物对细胞系 MDA-MD-231、T24 和 A549 的抗增殖活性。

Research background. The motivation of this study is to emphasize the importance of artificial intelligence (AI) and causality modelling of food quality and analysis with “big data”. AI with structural causal modelling (SCM), based on Bayes networks and deep learning, enables the integration of theoretical field knowledge in food technology with process production, physical-chemical analytics, and consumer organoleptic assessments. Food products have complex nature and data are highly dimensional, with intricate interrelations (correlations) and are difficult to relate to consumer sensory perception of food quality. Standard regression modelling techniques such as multiple ordinary least squares (OLS) and partial least squares (PLS) are effectively applied for the prediction by linear interpolations of observed data under cross-sectional stationary conditions. Upgrading linear regression models by machine learning (ML) accounts for nonlinear relations and reveals functional patterns, but is prone to confounding and fails predictions under unobserved nonstationary conditions. Confounding of data variables is the main obstacle to applications of the regression models in food innovations under previously untrained conditions. Hence, this manuscript focuses on applying causal graphical models with Bayes networks to infer causal relationships and intervention effects between process variables and consumer sensory assessment of food quality. Experimental approach. This study is based on the literature available data on the process of wheat bread baking quality, consumer sensory quality assessments of fermented milk products, and professional wine tasting data. The data for wheat baking quality are regularized by the least absolute shrinkage and selection operator (LASSO elastic net). Applied is Bayes statistics for evaluation of the model joint probability function for inferring the network structure and parameters. The obtained SCM models are presented as directed acyclic graphs (DAG). D-separation criteria is applied to block confounding effects in estimating direct and total causal effects of process variables and consumer perception on food quality. Probability distributions of causal effects of the intervention of individual process variables on quality are presented as partial dependency plots determined by Bayes neural networks. In the case of wine quality causality, the total causal effects determined by SCM models are positively validated by the double machine learning (DML) algorithm.Results and conclusions. Analysed is the data set of 45 continuous variables corresponding to different chemical, physical and biochemical variables of wheat properties from seven Croatian cultivars during two years of controlled cultivation. LASSO regularization of the data set yielded the ten key predictors, accounting for 98 % variance of the baking quality data. Based on the key variables derived is the quality predictive random forest model with 75 % cross
研究背景。本研究的动机是强调人工智能(AI)和食品质量因果关系建模以及 "大数据 "分析的重要性。基于贝叶斯网络和深度学习的人工智能与结构因果建模(SCM)能够将食品技术领域的理论知识与工艺生产、物理化学分析和消费者感官评估相结合。食品性质复杂,数据维度高,相互关系(相关性)错综复杂,很难与消费者对食品质量的感官认知联系起来。标准回归建模技术,如多重普通最小二乘法(OLS)和偏最小二乘法(PLS),在横截面静态条件下通过对观测数据的线性插值进行预测是非常有效的。通过机器学习(ML)升级线性回归模型可考虑非线性关系并揭示功能模式,但在未观察到的非稳态条件下,易受混杂因素影响且预测失败。数据变量的混杂是回归模型在以前未经训练的条件下应用于食品创新的主要障碍。因此,本手稿侧重于应用贝叶斯网络的因果图模型来推断过程变量与消费者对食品质量的感官评估之间的因果关系和干预效果。实验方法。本研究基于小麦面包烘焙质量过程的文献数据、消费者对发酵乳制品的感官质量评估以及专业品酒数据。小麦烘焙质量数据采用最小绝对收缩和选择算子(LASSO 弹性网)进行正则化处理。应用贝叶斯统计评估模型联合概率函数,以推断网络结构和参数。获得的单片机模型以有向无环图(DAG)的形式呈现。在估算过程变量和消费者感知对食品质量的直接和总体因果效应时,采用 D 分离标准来阻断混杂效应。单个过程变量的干预对质量的因果效应的概率分布以贝叶斯神经网络确定的部分依赖图的形式呈现。在葡萄酒质量因果关系的案例中,单片机模型确定的总因果效应通过双机器学习(DML)算法得到了积极验证。所分析的数据集包含 45 个连续变量,分别对应克罗地亚 7 个栽培品种在两年控制栽培期间小麦特性的不同化学、物理和生化变量。通过对数据集进行 LASSO 正则化,得出了 10 个关键预测因子,占烘焙质量数据方差的 98%。基于关键变量得出的质量预测随机森林模型的交叉验证准确率为 75%。质量和关键预测因子之间的因果关系分析是基于贝叶斯模型,以 DAG 图的形式描述。蛋白质含量显示了最重要的直接因果效应,相应的路径系数为 0.71,THMW(高分子谷蛋白亚基总量)含量是间接原因,路径系数为 0.42,蛋白质总平均因果效应(ACE)为 0.65。优质发酵乳产品的大数据集包括二进制消费者感官数据(味道、气味、浑浊度)、连续物理变量(温度、脂肪、pH 值、颜色)和消费者质量评估的三个等级。得出的质量分类预测随机森林模型的 "箱外"(OOB)误差为 0.28%。贝叶斯网络模型预测,口味分级的直接原因是温度、颜色和脂肪含量,而质量分级的直接原因是温度、浑浊度、气味和脂肪含量。估计的主要质量等级平均因果效应(ACE)为温度-0.04 级/°C 和质量等级 0.3 级/脂肪含量。温度 ACE 依赖性显示为非线性负饱和,"断裂 "点在 60 °C,而脂肪 ACE 呈正线性趋势。红葡萄酒和白葡萄酒的因果质量分析是基于由 11 个物理和化学性质连续变量组成的大型数据集,质量评估分为 10 个等级,从 1 到 10。每个等级都由一个专业品酒师小组进行三重分类。非结构性双机器学习算法(DML)被应用于整个 ACE 质量评估。红葡萄酒和白葡萄酒的酒精含量具有关键的正 ACE 相对因子 0.35 质量/酒精,而挥发性酸度具有关键的负 ACE -0.2 质量/酸度。

Research background. Peanut oil (Arachis hypogaea L.) is a rich source of unsaturated fatty acids. Consumption of peanut oil has been reported to have biological effects on human health. Unsaturated, especially poly-unsaturated fatty acids (PUFA), found in peanut oil are highly susceptible to oxidation, resulting in the formation of noxious compounds during processing and storage. The aim was to prevent peanut oil PUFA from oxidation by encapsulation in a protein-polysaccharide complex using the microwave drying process.Experimental approach. The combination effect of corn starch (CS) and whey protein isolate (WPI) was evaluated for ultrasound assisted microwave encapsulation of peanut oil to prevent oxidative degradation. The effect of independent parameters, viz. CS:WPI ratio (1:1 to 5:1), lecithin (0–5 %), ultrasonication (0–10 min) and microwave power (150–750 W) on encapsulation of peanut oil was evaluated using response surface methodology (RSM). The process responses viz., viscosity and stability of emulsion, encapsulation efficiency, peroxides value, antioxidant activity, free fatty acids (FFA), moisture, angle of repose and flowability (Hausner ratio, HR and Carr’s Index, CI) were recorded and analysed to optimize the independent variables.Results and conclusions. The viscosity of all the emulsions prepared for encapsulation by ultrasonication ranged 6.90 to 14.40 cP having more than 90 % stability over 7 days. The observed encapsulation efficiency was 21.82–74.25 % for encapsulated peanut oil. Encapsulation efficiency was significantly affected by CS:WPI ratio and ultrasonication. The peroxide value, antioxidant activity and FFA ranged between 1.789–3.723 mg/kg oil, 19.81–72.62 % and 0.042–0.127 %, respectively. Physical properties such as moisture content, angle of repose, HR and CI was observed 1.94–8.70 % (w.b.), 46.5–58.3⁰, 1.117–1.246 and 10.48–22.14 %, respectively. The physical properties were significantly affected by surface characteristics of the encapsulates. The higher efficiency (74.25 %) of the peanut oil encapsulation could be achieved at optimized condition of 1.25 CS:WPI ratio, 0.25 % lecithin, 9.99 min ultrasonication and 355.41 W microwave power.Novelty and scientific contribution. The findings contribute to the fields of food science and technology by offering a practical approach to preserving the nutritional quality of peanut oil and enhancing its stability by encapsulation, thereby promoting its potential health benefits for consumers and applications in various industries such as dairy and bakery.
研究背景。花生油(Arachis hypogaea L.)是不饱和脂肪酸的丰富来源。据报道,食用花生油对人体健康有生物学影响。花生油中的不饱和脂肪酸,尤其是多不饱和脂肪酸(PUFA)极易氧化,从而在加工和储存过程中形成有害化合物。研究的目的是利用微波干燥工艺将花生油中的 PUFA 包裹在蛋白质-多糖复合物中,防止其氧化。实验方法评估了玉米淀粉(CS)和乳清蛋白分离物(WPI)在超声波辅助微波封装花生油以防止氧化降解方面的组合效果。采用响应面方法(RSM)评估了独立参数,即 CS:WPI 比例(1:1 至 5:1)、卵磷脂(0-5%)、超声(0-10 分钟)和微波功率(150-750 瓦)对封装花生油的影响。记录并分析了工艺反应,即乳化液的粘度和稳定性、封装效率、过氧化值、抗氧化活性、游离脂肪酸(FFA)、水分、休止角和流动性(豪斯纳比率 HR 和卡尔指数 CI),以优化自变量。用超声波法制备的用于封装的所有乳液的粘度在 6.90 至 14.40 cP 之间,7 天内的稳定性超过 90%。观察到封装花生油的封装效率为 21.82-74.25%。封装效率受 CS:WPI 比例和超声波处理的影响很大。过氧化值、抗氧化活性和 FFA 分别为 1.789-3.723 mg/kg、19.81-72.62 % 和 0.042-0.127 %。水分含量、静止角、HR 和 CI 等物理性质分别为 1.94-8.70%(重量比)、46.5-58.3⁰、1.117-1.246 和 10.48-22.14%。封装物的表面特性对其物理性质有很大影响。在 CS:WPI 比例为 1.25、卵磷脂含量为 0.25%、超声时间为 9.99 分钟、微波功率为 355.41 W 的优化条件下,花生油的包封效率较高(74.25%)。该研究结果为食品科学与技术领域提供了一种实用的方法,通过封装来保持花生油的营养质量并提高其稳定性,从而促进其对消费者的潜在健康益处,并应用于乳制品和烘焙等多个行业。

Physical properties such as moisture content, angle of repose, HR and CI was observed 1.94–8.70 % (w.b.), 46.5–58.3⁰, 1.117–1.246 and 10.48–22.14 %, respectively. The physical properties were significantly affected by surface characteristics of the encapsulates. The higher efficiency (74.25 %) of the peanut oil encapsulation could be achieved at optimized condition of 1.25 CS:WPI ratio, 0.25 % lecithin, 9.99 min ultrasonication and 355.41 W microwave power.\u0000Novelty and scientific contribution. The findings contribute to the fields of food science and technology by offering a practical approach to preserving the nutritional quality of peanut oil and enhancing its stability by encapsulation, thereby promoting its potential health benefits for consumers and applications in various industries such as dairy and bakery.","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":"10 11","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139448783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research background. Aging is a biochemical, metabolic, and genetic physiological phenomenon. The suppression of melanin biosynthesis, evident in the graying of hair, is a hallmark of aging resulting from translation failure, reduced enzyme activity, and cellular senescence. Putrescine, the smallest member of the polyamine family and an organic chemical, is present in living mammalian cells, playing a crucial role in regulating skin melanogenesis. Therefore, the purpose of this study is to explore the effect of putrescine on the signaling pathways of melanogenesis in melanoma cells.Experimental approach. Putrescine was studied on the melanin production capacity was examined through a tyrosinase activity assay. To assess the cell viability of B16F1 cells exposed to putrescine, an MTT assay was performed. The impact of putrescine on melanin synthesis in the presence of H2O2 was evaluated using various in vitro assays in B16F1 cells. The effect of putrescine on melanin production in B16F1 cells was achieved through a dedicated melanin production assay. Gene expression analysis was conducted using RT-PCR. Furthermore, the impact of putrescine on the expression of proteins related to melanin production in H2O2-treated cells was examined through immunofluorescence and western blot analysis. Results and conclusions. Putrescine increased tyrosinase activity and demonstrated non-cytotoxicity in B16F1 cells. Furthermore, putrescine effectively scavenged H2O2, as evidenced by the reduction in intracellular H2O2 levels in DCFH-DA analysis, and promoted melanin production in living cells. The stimulation of melanogenesis by putrescine was attributed to the elevated expression of Mitf, Tyr, Trp-1, and Trp-2 genes. Immunofluorescence investigations revealed that putrescine enhanced the expression of proteins associated with melanogenesis and upregulated TYR, TRP-1, and TRP-2 via the MITF transcription factor and increased the expression of MSRA and MSRB in H2O2-treated cells, thereby effectively promoting melanogenesis. These findings suggest that putrescine may be utilized to stimulate melanin synthesis.Novelty and scientific contribution. Putrescine could be solely used as a cosmetic agent to prevent premature graying of hair.
研究背景。衰老是一种生化、代谢和遗传生理现象。由于翻译失败、酶活性降低和细胞衰老,黑色素的生物合成受到抑制,表现为头发变白,这是衰老的一个标志。普托瑞辛是多胺家族中最小的成员,也是一种有机化学物质,存在于哺乳动物的活细胞中,在调节皮肤黑色素生成方面起着至关重要的作用。因此,本研究的目的是探讨腐胺对黑色素瘤细胞黑色素生成信号通路的影响。实验方法:通过酪氨酸酶活性检测法研究普瑞巴林对黑色素生成能力的影响。为了评估暴露于石碱的 B16F1 细胞的活力,进行了 MTT 试验。在 H2O2 存在的情况下,使用各种体外试验评估了腐胺对 B16F1 细胞黑色素合成的影响。通过专用的黑色素生成试验,评估了腐胺对 B16F1 细胞黑色素生成的影响。基因表达分析是通过 RT-PCR 技术进行的。此外,还通过免疫荧光和 Western 印迹分析研究了腐胺对 H2O2 处理细胞中黑色素生成相关蛋白表达的影响。结果和结论苦参碱提高了 B16F1 细胞中酪氨酸酶的活性,并显示出无毒性。此外,从 DCFH-DA 分析中细胞内 H2O2 水平的降低可以看出,腐胺能有效清除 H2O2,并促进活细胞中黑色素的生成。腐霉利刺激黑色素生成的原因是 Mitf、Tyr、Trp-1 和 Trp-2 基因的表达升高。免疫荧光研究发现,腐霉利能增强黑色素生成相关蛋白的表达,通过MITF转录因子上调TYR、TRP-1和TRP-2,并增加H2O2处理细胞中MSRA和MSRB的表达,从而有效促进黑色素生成。这些研究结果表明,可利用腐胺刺激黑色素的合成。石灰华可单独用作化妆品,防止头发过早变白。

IF 2.4 4区 农林科学 Q3 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-01-02 DOI: 10.17113/ftb.62.01.24.8163

Research background. Enzymatically resistant maltodextrins (ERM) are a resistant starch (RS) type 4, synthesized from native starch. They are obtained through sequential application of two processes: pyrodextrinization (PDX), which produces pyrodextrins, and complementary hydrolysis (CH), which generates ERM. These processes produce atypical bonds and confer characteristics similar to dietary fiber to pyrodextrins and ERM, such as resistance to digestion. The objective of this work was to obtain and evaluate some physicochemical characteristics of pyrodextrins and ERM produced from native starch isolated from makal (Xanthosoma yucatanense) tubers.Experimental approach. PDX and CH were performed by applying factorial designs. For PDX, factors and their levels were starch concentration/2.2 M HCl ratio (80/1 and 160/1 m/V), temperature (90 and 110 °C), and reaction time (1 and 3 h); while for CH were α-amylase-pyrodextrin concentration (0.5 and 1 µL/mL) and reaction time (10 and 30 min). The physicochemical profile included determination of RS content, estimation of color change (ΔE), microscopy, and determination of dextrose equivalents (DE). Results and conclusions. The best factorial treatment for PDX was at the 160:1 m/V, 90 °C and 3 h levels since it presented the highest RS content (84.73 %) and a lowest ΔE (3.742). Due to its low DE (13.89 %), increased RS (90.73 %), and low ΔE (4.24), ERM resulting from CH with the 0.5 µL/mL α-amylase pyrodextrin concentration and 10 min levels was selected as the best treatment.Novelty and scientific contribution. Results show that pyrodextrins and ERM obtained from makal can be used as ingredients for functional foods development, due to their high proportion of non-digestible material and low browning degree.
研究背景。酶法抗性麦芽糊精(ERM)是一种抗性淀粉(RS),由天然淀粉合成。抗性麦芽糊精是由原生淀粉合成的抗性淀粉(RS)的第 4 类,通过连续应用两种工艺获得:热糊精化(PDX)和互补水解(CH),前者产生热糊精,后者产生抗性麦芽糊精。这些过程会产生非典型键,并赋予焦糊糊精和 ERM 类似于膳食纤维的特性,例如耐消化性。这项工作的目的是获得并评估从马卡尔(Xanthosoma yucatanense)块茎中分离出的原生淀粉生产的焦糊精和ERM的一些理化特性。采用因子设计法进行了 PDX 和 CH 试验。PDX 的因素及其水平为淀粉浓度/2.2 M HCl 比率(80/1 和 160/1 m/V)、温度(90 和 110 °C)和反应时间(1 和 3 h);CH 的因素及其水平为 α 淀粉酶-糊精浓度(0.5 和 1 µL/mL)和反应时间(10 和 30 分钟)。理化分析包括测定 RS 含量、估计颜色变化(ΔE)、显微镜检查和测定葡萄糖当量(DE)。结果和结论PDX 的最佳因子处理是在 160:1 m/V、90 °C 和 3 小时的条件下,因为它的 RS 含量最高(84.73%),ΔE 最低(3.742)。由于 DE 值低(13.89 %)、RS 含量高(90.73 %)、ΔE 值低(4.24),使用 0.5 µL/mL α 淀粉酶焦糊糊精浓度和 10 分钟水平的 CH 所产生的 ERM 被选为最佳处理方法。研究结果表明,从马卡尔中提取的焦糊精和ERM可用作开发功能性食品的原料,因为它们的非消化物质比例高,褐变程度低。

Research background. Peanut allergy poses a significant threat to human health due to the elevated risk of long-term morbidity at low doses. Modifying protein structure to influence sensitization is a popular topic. Experimental approach. In this study, the purified peanut allergen Ara h 1 was enzymatically hydrolysed using flavorzyme, alkaline protease or a combination of both. The binding ability of Ara h 1 to antibodies, and gene expression and secretion levels of the pro-inflammatory factors IL-5 and IL-6 in Caco-2 cells was measured. Changes in the secondary and tertiary structures before and after treatment with Ara h 1 were carried out by circular dichroism and SDS-PAGE.Results and conclusions. The results indicated a reduction in the allergenicity and pro-inflammatory ability of Ara h 1. The evaluation reveals that the flavorzyme and alkaline protease treatments caused particle shortening and aggregation. The fluorescence emission peak was enhanced, increasing by 3.4-fold upon combined treatment with both proteases. Additionally, the secondary structure underwent changes, and the hydrophobicity also increased (8.95-fold upon combined treatment). Novelty and scientific contribution. These findings provide an effective theoretical basis for developing a new method of peanut desensitization and partially uncovering the mechanism of peanut sensitization.

<p><strong>Research background: </strong>Increasing awareness of the importance of nutrition in health promotion and disease prevention has driven to the development of foods for special medical purposes (FSMPs). In this study, the probiotic strain <i>Lacticaseibacillus paracasei</i> ssp. <i>paracasei</i> (<i>Lacticaseibacillus casei</i> 431<sup>®</sup>) was incorporated into FSMPs to develop an innovative product. The aim was to investigate the influence of the FSMP matrix on the specific probiotic properties of <i>L. casei</i> 431<sup>®</sup> <i>in vitro</i>.</p><p><strong>Experimental approach: </strong>A series of <i>in vitro</i> experiments were performed as part of the probiotic approach. After evaluation of antibiotic susceptibility profiles, functional properties such as survival under simulated gastrointestinal tract (GIT) conditions, bile salt deconjugation activities, cholesterol assimilation, antagonistic activity against spoilage bacteria and adhesion to Caco-2 cell line monolayers and extracellular matrix proteins were investigated.</p><p><strong>Results and conclusions: </strong>The <i>L. casei</i> 431<sup>®</sup> strain, both the lyophilised strain and the strain isolated from the FSMP matrix, effectively survived the simulated adverse gastrointestinal conditions without significant effects of the food matrix. The effect of the FSMP matrix on the deconjugation activity of the bile salts of <i>L. casei</i> 431<sup>®</sup> was minimal; however, cholesterol assimilation was increased by 16.4 %. <i>L. casei</i> 431<sup>®</sup> had antibacterial activity against related lactic acid bacteria regardless of whether it was used in FSMPs or not. Conversely, the probiotic strain isolated from FSMP matrix had significantly higher inhibitory activity against six potential pathogens than the lyophilised culture. The autoaggregation ability of the <i>L. casei</i> 431<sup>®</sup> cells was not affected by the FSMP matrix. The adhesion of <i>L. casei</i> 431<sup>®</sup> bacterial cells to the extracellular matrix proteins was reduced after treatment with proteinase K, with the highest adhesion observed to laminin. The adhesion of <i>L. casei</i> 431<sup>®</sup> reduced the binding of <i>E. coli</i> 3014 by 1.81 log units and the binding of <i>S</i>.

研究背景:人们日益认识到营养对促进健康和预防疾病的重要性,这推动了特殊医学用途食品(FSMP)的开发。在本研究中,益生菌株副乳酸杆菌(Lacticaseibacillus paracasei ssp. paracasei)(Lacticaseibacillus casei 431®)被添加到 FSMP 中,以开发一种创新产品。其目的是研究 FSMP 基质对 L. casei 431® 的体外益生特性的影响:实验方法:作为益生菌方法的一部分,进行了一系列体外实验。实验方法:作为益生菌方法的一部分,进行了一系列体外实验。在对抗生素敏感性进行评估后,研究了功能特性,如在模拟胃肠道(GIT)条件下的存活率、胆盐解结合活性、胆固醇同化、对腐败菌的拮抗活性以及对 Caco-2 细胞系单层和细胞外基质蛋白的粘附性:L. casei 431® 菌株,无论是冻干菌株还是从 FSMP 基质中分离出来的菌株,都能在模拟的不良肠胃条件下有效存活,食品基质没有明显影响。FSMP 基质对干酪乳杆菌 431® 的胆汁盐解聚活性影响很小,但胆固醇同化率提高了 16.4%。无论是否在 FSMP 中使用,L. casei 431® 对相关乳酸菌都具有抗菌活性。相反,从 FSMP 基质中分离出来的益生菌株对六种潜在病原体的抑制活性明显高于冻干培养物。L. casei 431® 细胞的自动聚集能力不受 FSMP 基质的影响。经蛋白酶 K 处理后,L. casei 431® 细菌细胞对细胞外基质蛋白的粘附力降低,对层粘蛋白的粘附力最高。L. casei 431® 的粘附作用使大肠杆菌 3014 与 Caco-2 细胞系的结合力降低了 1.81 个对数单位,使伤寒杆菌 FP1 与 Caco-2 细胞系的结合力降低了 1.85 个对数单位,这表明它具有竞争性排斥这些病原体的潜力:研究结果表明,FSMP 基质对 L. casei 431® 的特定益生菌特性(如抗菌活性、胆盐解结合和胆固醇同化)具有积极影响,同时这种益生菌株的加入增加了 FSMP 的功能价值。通过联合应用 L. casei 431® 和创新的 FSMP 基质所产生的协同效应,有助于开发出具有附加值的改良功能食品的新配方。

In this study, the probiotic strain &lt;i&gt;Lacticaseibacillus paracasei&lt;/i&gt; ssp. &lt;i&gt;paracasei&lt;/i&gt; (&lt;i&gt;Lacticaseibacillus casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt;) was incorporated into FSMPs to develop an innovative product. The aim was to investigate the influence of the FSMP matrix on the specific probiotic properties of &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; &lt;i&gt;in vitro&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Experimental approach: &lt;/strong&gt;A series of &lt;i&gt;in vitro&lt;/i&gt; experiments were performed as part of the probiotic approach. After evaluation of antibiotic susceptibility profiles, functional properties such as survival under simulated gastrointestinal tract (GIT) conditions, bile salt deconjugation activities, cholesterol assimilation, antagonistic activity against spoilage bacteria and adhesion to Caco-2 cell line monolayers and extracellular matrix proteins were investigated.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results and conclusions: &lt;/strong&gt;The &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; strain, both the lyophilised strain and the strain isolated from the FSMP matrix, effectively survived the simulated adverse gastrointestinal conditions without significant effects of the food matrix. The effect of the FSMP matrix on the deconjugation activity of the bile salts of &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; was minimal; however, cholesterol assimilation was increased by 16.4 %. &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; had antibacterial activity against related lactic acid bacteria regardless of whether it was used in FSMPs or not. Conversely, the probiotic strain isolated from FSMP matrix had significantly higher inhibitory activity against six potential pathogens than the lyophilised culture. The autoaggregation ability of the &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; cells was not affected by the FSMP matrix. The adhesion of &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; bacterial cells to the extracellular matrix proteins was reduced after treatment with proteinase K, with the highest adhesion observed to laminin. The adhesion of &lt;i&gt;L. casei&lt;/i&gt; 431&lt;sup&gt;®&lt;/sup&gt; reduced the binding of &lt;i&gt;E. coli&lt;/i&gt; 3014 by 1.81 log units and the binding of &lt;i&gt;S&lt;/i&gt;.
