Egg-related research promises unique opportunities for food science and technology. There is an urgent need to develop non-destructive methodologies for defining key egg parameters, e.g., egg volume (V) and surface area (S), based only on egg images. Herewith, V can be measured using the Archimedes’ principle (i.e., dipping in water), while S can be inferred using formulae that include V as one of its variables. Although the Archimedes’ principle is the best approach for determining V, dipping an egg into water cannot be practicable. In this study, we derived the appropriate mathematical approaches to calculate V and S based on measurements of quail eggs’ linear parameters. The proposed calculation formulae are suitable for eggs of any shape and species. This innovative procedure can be employed as the basis of the most accurate of all existing methods for computing S and is suitable for both analytical and industrial measurements of V.

与鸡蛋有关的研究为食品科学和技术带来了独特的机遇。目前迫切需要开发非破坏性方法,仅根据鸡蛋图像来确定鸡蛋的关键参数,如鸡蛋体积()和表面积()。因此,可以使用阿基米德原理(即浸入水中)来测量,也可以使用包含变量之一的公式来推断。虽然阿基米德原理是确定鸡蛋体积的最佳方法,但将鸡蛋浸入水中并不可行。在这项研究中,我们根据对鹌鹑蛋线性参数的测量,推导出计算和的适当数学方法。提出的计算公式适用于任何形状和种类的蛋。这一创新程序可作为所有现有计算方法中最精确方法的基础,适用于......的分析和工业测量。

The objective of this work was the investigation of the kinetics of protein and C-phycocyanin extraction from Arthrospira platensis (Spirulina) biomass assisted by Pulsed Electric Fields (PEF). Fresh, untreated and PEF-treated (7.8 kV/cm, 0–137.6 kJ/kg) biomass was suspended in water and incubated at 30–50 °C for up to 24 h. Protein and C-phycocyanin recovery kinetics exhibited a sigmoidal behavior. The increase in treatment specific energy and incubation temperature up to 40 °C led to significant extraction acceleration. A treatment of 137.6 kJ/kg prior to incubation at 40 °C led to the minimization of protein characteristic incubation time (2.3 h vs. 14.4 h and 10.4 h of untreated sample at 30 and 40 °C, respectively). At 50 °C a significant reduction of the extraction yield was observed, due to the inactivation of the proteolytic enzymes. Higher treatment specific energy led to increased C-phycocyanin purity of the extracts at 40 °C. The maximization of the C-phycocyanin extract purity factor (1.14 vs 0.66 for untreated samples) was achieved with a PEF treatment at 137.6 kJ/kg and incubation at 40 °C for 3 h.

这项工作的目的是研究在脉冲电场(PEF)辅助下从(螺旋藻)生物质中提取蛋白质和 C-花青素的动力学。将未经处理和经 PEF 处理(7.8 kV/cm,0-137.6 kJ/kg)的新鲜生物质悬浮于水中,在 30-50 °C 下培养 24 小时。蛋白质和 C-phycocyanin(C-花青素)的恢复动力学表现为曲线行为。处理比能量和培养温度提高到 40 °C,萃取速度明显加快。在 40 °C 下培养前进行 137.6 kJ/kg 的处理可最大限度地缩短蛋白质特征培养时间(2.3 小时,而在 30 °C 和 40 °C 下未经处理的样品分别为 14.4 小时和 10.4 小时)。在 50 °C 时,由于蛋白水解酶失活,提取率明显下降。在 40 °C 时,较高的处理比能量可提高提取物中 C-phycocyanin 的纯度。137.6 kJ/kg 的 PEF 处理和 40 °C 培养 3 小时可使 C-花青素提取物纯度系数最大化(1.14 对未处理样品的 0.66)。

The impact of enzyme-assisted (EAE), microwave-assisted (MAE), and microwave enzyme-assisted (MEAE) extractions using water were evaluated and compared to aqueous (AEP), conventional ethanolic (CSE), and microwave ethanolic (MSE) controls for the release of phenolics from Cabernet Sauvignon grape pomace. Optimization of extract total phenolic content (TPC) involved stepwise screening of time, temperature, slurry pH, solids-to-liquid ratio, and enzyme conditions. The use of 0.1 % alkaline protease in MEAE (1:10 g pomace/mL water, pH 11.5, 70 °C, 30 min) reduced extraction time by 50 % compared to AEP, EAE, and CSE methods, doubling the TPC of the extracts to 100.9 mg GAE/g dry weight pomace compared to ethanolic extractions. MAE and MEAE extracts exhibited in vitro antioxidant activities (ABTS and ORAC) similar to ethanolic extracts and had greater antioxidant activities than AEP/EAE extracts while boosting relative contents of catechins, procyanidins, trans-piceid, and malvidin-3,5-diglucoside as detected by untargeted metabolomics. Quantitation by HPLC showed increased levels of gallic acid, protocatechuic acid, syringic acid, p-coumaric acid, polymeric phenols, and polymeric pigments in MEAE compared to hydroethanolic methods. Scanning electron microscopy further supported the synergistic role of microwave processing and proteolysis in disrupting the grape cell structure to aid in releasing valuable bioactive phenolic compounds.

评估了水酶法(EAE)、微波酶法(MAE)和微波酶法(MEAE)萃取对赤霞珠葡萄渣中酚类物质释放的影响,并与水法(AEP)、传统乙醇法(CSE)和微波乙醇法(MSE)对照进行了比较。提取物总酚含量(TPC)的优化涉及时间、温度、浆液 pH 值、固液比和酶条件的逐步筛选。与AEP、EAE和CSE方法相比,在MEAE(1:10 g果渣/mL水,pH 11.5,70 °C,30分钟)中使用0.1 %的碱性蛋白酶可将萃取时间缩短50%,与乙醇萃取相比,萃取物的总酚含量翻了一番,达到100.9 mg GAE/g果渣干重。MAE 和 MEAE 提取物的体外抗氧化活性(ABTS 和 ORAC)与乙醇提取物相似,并且比 AEP/EAE 提取物具有更高的抗氧化活性,同时提高了儿茶素、原花青素、反式冰片苷和麦冬苷-3,5-二葡萄糖苷的相对含量(通过非靶向代谢组学检测)。高效液相色谱法的定量分析显示,与水乙醇法相比,MEAE 中没食子酸、原儿茶酸、丁香酸、对香豆素、聚合酚和聚合色素的含量有所增加。扫描电子显微镜进一步证实了微波处理和蛋白水解在破坏葡萄细胞结构以帮助释放有价值的生物活性酚类化合物方面的协同作用。

This study evaluates the performance and storage stability of functional extrudates enriched with natural additives, utilizing advanced food engineering and processing techniques. Essential oils from oregano, rosemary, hypericum, and chamomile were incorporated in both free and encapsulated forms using electrohydrodynamic processing, spray drying, and freeze drying, and added to the food matrix through extrusion processing. The encapsulated additives demonstrated superior retention and controlled release of bioactive compounds, with spray-dried agents achieving the highest total phenolic content (1.66 mg GAE/g) post-extrusion. During storage, these extrudates exhibited enhanced stability with low degradation rate constants (1.90×10⁻³ days⁻¹ at aw=0.33, 25°C, over 240 days). The bioactive extrudates maintained remarkable stability in terms of hardness and colour change, with hardness inversely correlated to moisture content. These findings highlight the potential of using encapsulation and extrusion processing to create stable, naturally bioactive food products, reducing dependence on synthetic additives. The research underscores the integration of emerging technologies in food science to enhance the stability and delivery of essential oils, supporting the development of sustainable and health-promoting food systems.

本研究利用先进的食品工程和加工技术,对添加了天然添加剂的功能性挤出物的性能和储存稳定性进行了评估。利用电流体动力加工、喷雾干燥和冷冻干燥技术,将牛至精油、迷迭香精油、金丝桃精油和洋甘菊精油以游离和封装两种形式添加到挤压加工食品基质中。封装添加剂显示出生物活性化合物出色的保留和控制释放能力,其中喷雾干燥添加剂在挤压后的总酚含量最高(1.66 毫克 GAE/克)。在储存过程中,这些挤出物表现出更高的稳定性,降解率常数较低(1.90×10-³天-¹,=0.33,25°C,超过 240 天)。生物活性挤出物在硬度和颜色变化方面保持了显著的稳定性,硬度与水分含量成反比。这些发现凸显了利用封装和挤压加工制造稳定、天然生物活性食品的潜力,从而减少了对合成添加剂的依赖。这项研究强调了食品科学中新兴技术的整合,以提高精油的稳定性和输送,支持可持续和促进健康的食品体系的发展。

Gamma irradiation (γ-irradiation) sterilizes and modifies proteins. This study aimed to enhance the performance of protein hydrolysates of fermented tilapia fish skin using irradiation. The results showed that γ-irradiation could effectively kill harmful microorganisms in fish skin at 6 kGy. Irradiation at 1–6 kGy dose disintegrated the internal structure of fish skin proteins, thus increasing the degree of hydrolysis after fermentation by Bacillus subtilis L4; however, irradiation at 9–12 kGy caused cross-linking and aggregation of fish skin proteins. The solubility, and water and oil holding capacity of the protein hydrolysates were significantly improved compared to those of the non-irradiated sample. The maximum emulsifying activity (164.61±16.28 m2/g), foaming activity (91.13±2.30 mL), and surface hydrophobicity index (5766.43±770.56) were observed in the protein hydrolysates fermented from fish skin irradiated at 12 kGy. The antioxidant activity of the protein hydrolysates increased with increasing irradiation doses. This suggested that the functional properties and antioxidant activity of protein hydrolysates from fish skin fermentation can be improved by appropriate irradiation pretreatment, providing a feasible method for improving the utilization and quality of proteins in fishery waste.

伽马辐照(γ-辐照)可对蛋白质进行灭菌和改性。本研究旨在利用辐照提高发酵罗非鱼皮蛋白质水解物的性能。结果表明,γ-辐照在 6 kGy 下可有效杀死鱼皮中的有害微生物。1-6 kGy剂量的辐照可瓦解鱼皮蛋白质的内部结构,从而提高枯草杆菌L4发酵后的水解程度;但9-12 kGy剂量的辐照会导致鱼皮蛋白质交联和聚集。与未经过辐照的样品相比,水解蛋白的溶解度、持水量和持油量都有明显提高。辐照 12 kGy 的鱼皮发酵蛋白水解物的乳化活性(164.61±16.28 m2/g)、发泡活性(91.13±2.30 mL)和表面疏水指数(5766.43±770.56)均达到最大值。蛋白质水解物的抗氧化活性随着辐照剂量的增加而增加。这表明,通过适当的辐照预处理可以改善鱼皮发酵蛋白水解物的功能特性和抗氧化活性,为提高渔业废弃物中蛋白质的利用率和质量提供了一种可行的方法。

Valorization of brewer's spent grains (BSG) through alkaline hydrogen peroxide processing: Effect on composition, structure and rheological properties 通过碱性过氧化氢处理啤酒糟(BSG)实现其价值:对成分、结构和流变特性的影响

This study investigated the impact of alkaline processing with hydrogen peroxide (AHP) on the chemical composition, structure, and rheological properties of brewer's spent grains (BSG). Suspensions with different concentrations of BSG (2–8 %) and AHP (1–8 %) were subjected to different processing times (0–12 h). The BSG chemical composition, morphology, crystallinity, modifications of functional groups, and rheological behavior were evaluated over processing. Increasing the concentration of AHP in the suspension and the processing time improved the removal of proteins, lignin, and extractives from BSG into the suspension and, consequently, increased the cellulose and hemicellulose content in the processed BSG. On the other hand, higher concentrations of BSG in the suspension slightly reduced the removal efficiency of these components. AHP processing also induced thinning of the cell wall and changes in particle shape. These changes together with the increase in crystallinity of the processed BSG indicated the material destructuring. FTIR spectra showed reduced intensity of lignin and protein post-processing, indicating their removal, while peaks related to cellulose and hemicellulose increased in processed BSG. The flow curves of the suspensions were adjusted to the Herschel-Bulkley model, exhibiting non-Newtonian behavior with flow yield stress (1.529 Pa < τ0 < 4.646 Pa) and pseudoplasticity (0.830 < n < 0.969) in all conditions. Flow resistance increased with increasing concentration of AHP, BSG, and processing time. Notably, the increase in processing time resulted in greater removal of BSG components, especially proteins, lignin, and extractives, which significantly contributed to the increase in both the flow yield stress and the consistency index of the suspensions. All this information is useful and will support the design of equipment and processes, especially those involving the extraction of proteins and the conversion of the BSG lignocellulose fraction into biofuels.

本研究探讨了用过氧化氢(AHP)进行碱性处理对啤酒糟(BSG)的化学成分、结构和流变特性的影响。不同浓度的 BSG(2-8 %)和 AHP(1-8 %)悬浮液经过不同的处理时间(0-12 小时)。在加工过程中,对 BSG 的化学成分、形态、结晶度、官能团的改变以及流变行为进行了评估。提高悬浮液中 AHP 的浓度和加工时间,可将 BSG 中的蛋白质、木质素和萃取物去除到悬浮液中,从而提高加工后 BSG 中纤维素和半纤维素的含量。另一方面,悬浮液中 BSG 的浓度越高,去除这些成分的效率就越低。AHP 处理还导致细胞壁变薄,颗粒形状发生变化。这些变化以及加工后 BSG 结晶度的增加表明材料发生了重组。傅立叶变换红外光谱显示,加工后木质素和蛋白质的强度降低,表明它们已被去除,而纤维素和半纤维素的相关峰值在加工后的 BSG 中有所增加。悬浮液的流动曲线根据赫歇尔-布克雷模型进行了调整,在所有条件下均表现出流动屈服应力(1.529 Pa < τ0 < 4.646 Pa)和假塑性(0.830 < n < 0.969)的非牛顿行为。流动阻力随着 AHP、BSG 浓度和加工时间的增加而增加。值得注意的是,加工时间的增加导致 BSG 成分,尤其是蛋白质、木质素和萃取物的去除量增加,从而显著提高了悬浮液的流动屈服应力和稠度指数。所有这些信息都非常有用,将有助于设备和工艺的设计,尤其是涉及提取蛋白质和将 BSG 木质纤维素部分转化为生物燃料的设备和工艺。

To address the limitations of conventional hot air drying (HAD) for potato dehydration, pulsed vacuum drying (PVD) and humidity-controlled HAD (HC-HAD) were proposed as innovative techniques. In PVD, varying vacuum pulse durations (6, 8, 10, 12, and 14 min) and atmospheric pulse durations (2, 3, 4, and 5 min) were investigated. Under HC-HAD, different humidity control scenarios (40,30+30,90+CF, 50,30+30,90+CF, 40,30+CF, and 50,30+CF) were examined. The study revealed that a 14:2 duration pulsing in PVD retained the color and achieved the highest total phenol content (TPC) and antioxidation activity (conserving 97.50 % and 84.67 % of their fresh values, respectively) but had the longest drying time (260.00 min) compared to HC-HAD and HAD (139.45 min). The 50,30+CF strategy of HC-HAD exhibited the quickest drying time (116.79 min), maintained the color, TPC (87.97 % of the fresh value), and antioxidation activity (71.40 % of the fresh value), and achieved the best potato microstructure and starch structure. Furthermore, Artificial Neural Network simulations for HC-HAD conditions demonstrated significant reliability. These findings provide valuable insights for potato researchers and producers seeking to enhance preservation techniques and prolong the shelf life of potatoes as a staple crop.

为了解决传统热空气干燥(HAD)在马铃薯脱水方面的局限性,提出了脉冲真空干燥(PVD)和湿度控制 HAD(HC-HAD)这两种创新技术。在 PVD 中,研究了不同的真空脉冲持续时间(6、8、10、12 和 14 分钟)和大气脉冲持续时间(2、3、4 和 5 分钟)。在 HC-HAD 条件下,研究了不同的湿度控制方案(40,30+30,90+CF、50,30+30,90+CF、40,30+CF 和 50,30+CF)。研究结果表明,在 PVD 中以 14:2 的持续时间进行脉动,可以保持颜色,获得最高的总酚含量(TPC)和抗氧化活性(分别保留了新鲜值的 97.50 % 和 84.67 %),但与 HC-HAD 和 HAD(139.45 分钟)相比,干燥时间(260.00 分钟)最长。采用 50,30+CF 策略的 HC-HAD 干燥时间最快(116.79 分钟),保持了马铃薯的色泽、TPC(鲜值的 87.97%)和抗氧化活性(鲜值的 71.40%),并获得了最佳的马铃薯微观结构和淀粉结构。此外,对 HC-HAD 条件进行的人工神经网络模拟也显示出显著的可靠性。这些研究结果为马铃薯研究人员和生产者提高马铃薯保存技术和延长马铃薯作为主食作物的货架期提供了宝贵的见解。

Effective management of ethylene along the value chain is crucial to the regulation of fruit ripening and senescence to reduce postharvest losses. The objectives of this study were to, (i) investigate the degradation kinetics of ethylene using a vacuum ultraviolet (VUV) photolysis reactor at different light intensity (0.0005 mW/m2, 0.0014 mW/m2 and 0.0021 mW/m2) and relative humidity (RH) levels (20 % and 80 %), and (ii) evaluate the economic feasibility of the VUV photolysis system. Kinetic experiments were performed in batch mode with an initial ethylene concentration of 51 mg L−1. The reaction order and rate constant were determined by employing an nth-order kinetic model. Light intensity and RH significantly influenced the kinetic parameters and ethylene degradation (p < 0.05). At low light intensity, ethylene degradation followed a zero-order kinetic model, while at high intensity, it followed a fractional-order kinetic model. The developed kinetic models accurately predicted the experimental concentrations (R2 = 0.9955). The economic feasibility of the VUV photolysis system was assessed using electrical energy per order (EEO), which remained below 10 kW m-³ order−1, indicating energy efficiency and practical applicability. The chamber equipped with the VUV reactor successfully preserved apple quality (maintaining low TSS/TA ratio and delaying pH increase) during storage for 28 d at 15°C compared to the control. This foundational application of VUV photolysis in ethylene degradation offers promising prospects of upscaling for long-term storage investigation and industry applications.

价值链中乙烯的有效管理对于调节果实成熟和衰老以减少采后损失至关重要。本研究的目的是:(i) 利用真空紫外线(VUV)光解反应器,在不同光照强度(0.0005 mW/m2、0.0014 mW/m2 和 0.0021 mW/m2)和相对湿度(RH)水平(20% 和 80%)下,研究乙烯的降解动力学;(ii) 评估 VUV 光解系统的经济可行性。动力学实验以间歇模式进行,初始乙烯浓度为 51 mg L-1。反应顺序和速率常数是通过 nth-阶动力学模型确定的。光照强度和相对湿度对动力学参数和乙烯降解有明显影响(p < 0.05)。在低光照强度下,乙烯降解遵循零阶动力学模型,而在高光照强度下,乙烯降解遵循分数阶动力学模型。建立的动力学模型准确预测了实验浓度(R2 = 0.9955)。采用每阶电能(EEO)评估了紫外光分解系统的经济可行性,结果显示每阶电能低于 10 kW m-³-阶-1,这表明该系统具有能源效率和实用性。与对照组相比,配备了紫外光反应器的箱体在 15°C 下贮藏 28 d 期间成功地保持了苹果的品质(保持了较低的 TSS/TA 比值并延缓了 pH 值的升高)。紫外线光解在乙烯降解中的这一基础应用为长期贮藏研究和工业应用提供了广阔的升级前景。

Diabetes is a metabolic disorder characterized by hyperglycemia and is a disease with an increasing prevalence. Hyperglycemia triggers abnormalities in the metabolism of carbohydrates, proteins, fats, and can cause complications. This disease is caused by poor lifestyles, such as food consumption patterns and lack of physical activity, and what is more potential is genetics. In this regard, efforts are being made to increase self-awareness on food intake and developing functional food which can be done by the food industry. Many studies have been conducted to find bioactive compounds from natural ingredients that can prevent and treat diabetes. The effectiveness of bioactive compounds in preventing and treating diabetes is influenced by how these compounds reach their target. Nanotechnology can be a solution in the process of encapsulating anti-diabetic bioactive compounds into processed foods with the aim of stabilizing the function of these compounds in the processed food matrix, up to their absorption in the body. In this context, innovations are needed to develop a commercially viable and efficient delivery system, while industrial applications also need to be scaled up following scientific validation at the laboratory level. In addition, ethical, safety, and regulatory aspects should also be considered during the development of a delivery system for bioactive compounds. In these perspectives, this review highlights nanoencapsulation of anti-diabetic compounds in food, nanodelivery systems, market trends in bioactive-based anti-diabetic food products, and future perspectives.

糖尿病是一种以高血糖为特征的代谢紊乱疾病,发病率越来越高。高血糖会引发碳水化合物、蛋白质、脂肪代谢异常,并可能引起并发症。造成这种疾病的原因是不良的生活方式,如食物消费模式和缺乏体育锻炼,更潜在的原因是遗传。在这方面,人们正在努力提高对食物摄入量的自我意识,并开发功能性食品,这可以由食品工业来完成。已经开展了许多研究,从天然成分中寻找可以预防和治疗糖尿病的生物活性化合物。生物活性化合物预防和治疗糖尿病的效果受到这些化合物如何到达目标的影响。在将抗糖尿病生物活性化合物封装到加工食品中的过程中,纳米技术可以作为一种解决方案,目的是稳定这些化合物在加工食品基质中的功能,直至被人体吸收。在这种情况下,需要进行创新,以开发出商业上可行的高效输送系统,同时还需要在实验室进行科学验证后扩大工业应用。此外,在开发生物活性化合物递送系统的过程中,还应考虑道德、安全和监管方面的问题。从这些角度出发,本综述重点介绍了食品中抗糖尿病化合物的纳米封装、纳米给药系统、基于生物活性的抗糖尿病食品的市场趋势以及未来展望。

Bread is one of the prime foods consumed globally, and the demand for nutritious and gluten-free variants is progressively escalating. In recent years, alternative flours have gained popularity due to their recognized health advantages and potential in controlling food wastage. Prickly pear peels, a by-product of the fruit industry, offer a valuable prospect for augmenting the nutritional profile of bread and fostering sustainable practices. Consequently, the principal objective of this study was to explore the production of both wheat-based and gluten-free bread varieties fortified with prickly pear cv 'Rossa', 'Gialla', and 'Bianca' peels flour. Prickly pear peels were collected, dried, and processed into flour, thus serving as a partial substitute for conventional wheat and gluten-free flour breads that underwent a thorough evaluation of textural, nutritional, and biological properties before and after simulated gastric digestion. The observed results emphasized that incorporating prickly pear peel flour into bread formulations led to an increase in total phenolic content from 0.7 to 5 mgGAE/gbread, as well as enhanced antioxidant activity, from 0.5 to 5 mgGAE/kgbread. Furthermore, this incorporation resulted in heightened ash and fiber content, with gluten-free bread also showing a notable more than two-fold increase in protein levels. Moreover, the impact of digestion demonstrated a 30–50 % diminishing effect on the biological attributes of each sample; nevertheless, the enriched bread variants exhibited substantial retentions of polyphenolic compounds and a pronounced antioxidant capacity, underscoring their prospective utility as innovative food products while concurrently contributing to sustainability objectives through waste reduction.

面包是全球消费的主要食品之一,人们对营养丰富的无麸质面包的需求也在逐步升级。近年来,替代面粉因其公认的健康优势和控制食品浪费的潜力而越来越受欢迎。刺梨果皮是水果业的副产品,为增加面包的营养成分和促进可持续发展提供了宝贵的前景。因此,本研究的主要目的是探索用刺梨品种 "Rossa"、"Gialla "和 "Bianca "果皮粉生产小麦面包和无麸质面包的方法。采集、干燥刺梨果皮并加工成面粉,从而部分替代传统的小麦和无麸质面粉面包,在模拟胃消化前后对其质地、营养和生物特性进行了全面评估。观察结果表明,在面包配方中加入刺梨果皮粉后,总酚含量从 0.7 mgGAE/gbread 增加到 5 mgGAE/gbread,抗氧化活性也从 0.5 mgGAE/kgbread 提高到 5 mgGAE/kgbread。此外,这种添加还提高了灰分和纤维含量,无麸质面包的蛋白质含量也显著增加了两倍多。此外,消化对每个样品的生物属性都有 30-50% 的减弱影响;尽管如此,富集面包变体仍保留了大量的多酚化合物和明显的抗氧化能力,这表明它们有望成为创新食品,同时通过减少浪费实现可持续发展目标。
