Complex cohesions were formed through electrostatic interactions between gelatin (GE) and gum arabic, sodium carboxymethyl cellulose, pectin, and sodium alginate (SA). Of them, GE and SA served as an ideal wall material for encapsulating oregano essential oil (OEO). Applying the composite coalescence method, we here generated unique encapsulated OEO microcapsules (EOMs) by using GE–SA as the microcapsule wall material and OEO as the core material. At a concentration of 1 % (w/v), a core-to-wall ratio of 1:2, a recoalescence reaction temperature of 45 °C, and an emulsifier concentration of 5 % (w/w), EOMs exhibited excellent performance. Under the optimal conditions, the prepared EOMs (average particle size: 78.389 μm) had a homogeneous and complete spherical structure. Freeze-dried EOMs had a high encapsulation efficiency (71.20 %) and payload (56.08 %). Fourier transform infrared spectroscopy unveiled the presence of electrostatic interactions between GE and SA. The OEO in the EOMs had higher thermal stability and more stable antioxidant properties than the free OEO. Furthermore, in aqueous, acidic, oily, and alcoholic environments, EOMs exhibited some degree of slow-release ability. Additionally, EOMs exhibited strong antibacterial properties, with effective inhibition of Escherichia coli (E. coil), Staphylococcus aureus (S. aureus), and Curvularia lunata (C. lunata). Among them, the strongest inhibitory effect was on C. lunata. In summary, microcapsules prepared using GE–SA as a wall material had effectively improved OEO degradation-protecting, which enhanced the stability of OEO and controlled its antioxidant properties. Meanwhile, the microcapsules exhibited excellent antibacterial properties. This system exerted considerable potential in protecting the stability of essential oils and realizing slow release.

明胶(GE)与阿拉伯树胶、羧甲基纤维素钠、果胶和海藻酸钠(SA)之间通过静电作用形成了复杂的内聚力。其中,明胶和海藻酸钠是封装牛至精油(OEO)的理想壁材。在此,我们采用复合凝聚法,以 GE-SA 作为微胶囊壁材料,以 OEO 作为核心材料,生成了独特的封装 OEO 微胶囊(EOMs)。在浓度为1%(w/v)、芯壁比为1:2、再凝聚反应温度为45℃、乳化剂浓度为5%(w/w)的条件下,EOM表现出优异的性能。在最佳条件下,制备的 EOMs(平均粒径:78.389 μm)具有均匀完整的球形结构。冷冻干燥的EOM具有较高的封装效率(71.20%)和有效载荷(56.08%)。傅立叶变换红外光谱显示,GE和SA之间存在静电相互作用。与游离的 OEO 相比,EOMs 中的 OEO 具有更高的热稳定性和更稳定的抗氧化性。此外,在水性、酸性、油性和酒精环境中,EOMs 都表现出一定程度的缓释能力。此外,EOMs 还具有很强的抗菌特性,能有效抑制大肠杆菌(E. coil)、金黄色葡萄球菌(S. aureus)和月橘属(C. lunata)。其中,对月牙弧菌的抑制作用最强。综上所述,以GE-SA为壁材制备的微胶囊能有效改善OEO的降解保护作用,提高OEO的稳定性,控制其抗氧化性。同时,微胶囊还具有优异的抗菌性能。该体系在保护精油的稳定性和实现缓释方面具有相当大的潜力。

IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-15 DOI: 10.1016/j.fbp.2024.08.004

Baijiu is a unique alcoholic beverage in China, prepared through a traditional solid-state fermentation process. Daqu, recognized as the earliest form of crude enzyme preparation, plays a crucial role in determining the quality of Baijiu. Due to the enzymatic process derived from natural fermentation, the differences between regions were expected to occur. To compare regional-difference in microbial diversity and the functional profile of Daqu, metagenomic sequencing, physicochemical analysis, and electronic sensory evaluation were utilized. The results showed that bacteria and fungi were the main microbes in low-temperature Daqu (LTD), and their ratio of abundance was approximately 9:1. Streptomyces (20.27 %) and Bacillus licheniformis (15.28 %) emerged as the most dominant microbes in LTD at the genus and species levels, respectively. The overall microbial communities and functional profiles of Daqu between the two regions exhibited significant differences (P < 0.05). Bacillus licheniformis was significantly enriched in LTD from Taiyuan (P < 0.05) and mainly contributed to the saccharifying power, fermenting power, esterifying power, and liquefying power of LTD, demonstrating its important role in maintaining LTD quality. LTD from Taiyuan had a significantly higher fermenting power, esterifying power, and liquefying power than LTD from Suizhou (P < 0.05). In addition, a higher abundance of genes responsible for lactate production was detected in LTD from Suizhou, whereas genes associated with acetate production were enriched in LTD from Taiyuan. Collectively, these findings indicated that lactic acid bacteria may play a more important role in LTD from Suizhou, whereas acetate-producing bacteria may have a greater contribution to LTD from Taiyuan. This study provides a reference for microbial regulation during the production process of Daqu, and control of quality and traceability of the origin of Daqu.

白酒是中国特有的酒类饮品,通过传统的固态发酵工艺酿制而成。大曲被认为是最早的粗酶制剂,在决定白酒质量方面起着至关重要的作用。由于酶制剂工艺源于自然发酵,因此不同地区之间会存在差异。为了比较大曲微生物多样性和功能特征的地区差异,研究人员采用了元基因组测序、理化分析和电子感官评价等方法。结果表明,细菌和真菌是低温大曲(LTD)中的主要微生物,其丰度比约为 9:1。链霉菌(20.27%)和地衣芽孢杆菌(15.28%)分别是低温大曲中最主要的属和种级微生物。两个地区之间的整体微生物群落和大曲的功能特征表现出显著差异(P < 0.05)。地衣芽孢杆菌在太原产大曲中显著富集(P < 0.05),主要贡献于大曲的糖化力、发酵力、酯化力和液化力,表明其在维持大曲品质中的重要作用。太原LTD的发酵力、酯化力和液化力明显高于随州LTD(P < 0.05)。此外,在随州的乳酸菌中还发现了较多的产生乳酸的基因,而在太原的乳酸菌中则富集了产生醋酸的基因。这些研究结果表明,乳酸菌在随州的LTD中可能发挥着更重要的作用,而醋酸菌在太原的LTD中可能有更大的贡献。这项研究为大曲生产过程中的微生物调控、大曲质量控制和产地溯源提供了参考。

Preparation of water-soluble dietary fiber from bamboo shoots by fungi fermentation and its supplementation in biscuits 用真菌发酵法制备竹笋水溶性膳食纤维及其在饼干中的添加量
IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-14 DOI: 10.1016/j.fbp.2024.08.005

Expanding the utilization of bamboo shoots is extremely meaningful in China because of the high output every year. In this study, the bamboo shoot powder was used as a substrate to produce water-soluble dietary fiber (WSDF) by fermentation with a screened fungi strain Trichoderma dorotheae MLG23, and the prepared WSDF was utilized in the production of biscuits. The bamboo shoots and their residues, WSDF, and biscuits were analyzed on Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), inductively coupled plasma mass spectrometry (ICP-MS), and texture analyzer. The results showed that the fungi exhibited a strong ability to express extracellular cellulase. The enzymatic activities of filter paper activity (FPA), cellobiohydrolase (CBH), and -glucosidase (BG) secreted by the strain showed the highest at 50 °C, reaching 0.13, 0.19, and 1.20 U/mL, respectively, and the highest enzymatic activity of endoglucanase (EG) with 0.37 U/mL was obtained at 60 °C. The highest WSDF yield of 45.97 wt% was obtained under the fermentation conditions of bamboo shoot loading 30 g/L, strain inoculum 1010 CFU/L, and fermentation time 4 d at 30 °C. The cellulose and hemicellulose in bamboo shoots were partially utilized by the fungi to produce WSDF. The main metal elements in WSDF were Mg, K, Ca, and Zn. The hardness, cohesion, chewiness, resilience, and adhesion of the biscuits showed a gradual decrease with the increase of WSDF addition in the range from 0 to 10 g per 100 g of low gluten flour. The incorporation of WSDF disrupted the network structure of the gluten, leading to the reduction of some textural properties and the change of microstructure. These results showed a potential utilization of bamboo shoot in production of WSDF and functional biscuits.

由于中国每年都有大量的竹笋产出,因此扩大竹笋的利用率在中国是非常有意义的。本研究以竹笋粉为基质,用筛选出的真菌菌株毛霉 MLG23 发酵生产水溶性膳食纤维(WSDF),并将制备的水溶性膳食纤维用于饼干的生产。对竹笋及其残渣、WSDF 和饼干进行了傅立叶变换红外光谱(FT-IR)、X 射线光电子能谱(XPS)、扫描电子显微镜(SEM)、电感耦合等离子体质谱(ICP-MS)和质构分析仪分析。结果表明,真菌表达胞外纤维素酶的能力很强。菌株分泌的滤纸活性(FPA)、纤维素水解酶(CBH)和ꞵ-葡萄糖苷酶(BG)的酶活在 50 ℃时最高,分别达到 0.13、0.19 和 1.20 U/mL,内切葡聚糖酶(EG)的酶活在 60 ℃时最高,为 0.37 U/mL。在竹笋负载量为 30 g/L、菌株接种量为 1010 CFU/L、发酵温度为 30 ℃、发酵时间为 4 d 的发酵条件下,WSDF 产率最高,为 45.97 wt%。竹笋中的纤维素和半纤维素被真菌部分利用,产生了 WSDF。WSDF 中的主要金属元素为 Mg、K、Ca 和 Zn。在每 100 克低筋面粉中添加 0 至 10 克 WSDF 的范围内,饼干的硬度、内聚力、咀嚼性、回弹性和附着力随着 WSDF 添加量的增加而逐渐降低。WSDF 的加入破坏了面筋的网络结构,导致一些质构特性的降低和微观结构的改变。这些结果表明了利用竹笋生产 WSDF 和功能饼干的潜力。

Effect of flow patterns on recovery of invertases from Saccharomyces cerevisiae using polyethylene glycol/magnesium sulfate system in microchannels 在微通道中使用聚乙二醇/硫酸镁体系的流动模式对从酿酒酵母中回收转化酶的影响
IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-14 DOI: 10.1016/j.fbp.2024.08.003

The use of microdevices in extraction processes in aqueous two-phase systems (ATPS) has been studied for years in the literature. However, the effects of flow patterns still need to be adequately explored, especially for real samples. In this sense, the present study investigated the performance of microdevices in the recovery and partial purification of invertases with varying flow patterns. The invertases from Saccharomyces cerevisiae and the polyethylene glycol 1500/magnesium sulfate system were used in the experiments. Beyond the flow pattern, the study sought to maximize recovery and purification factor (PF) values by varying other operating conditions, including residence time, volumetric ratio, and channel diameter. It was observed that the short slug and long slug patterns showed better separation performance than the parallel pattern regardless of residence time and volumetric ratio. Increasing the residence time from 15 to 35 min increased the top recovery and PF values by two times, indicating that S. cerevisiae invertase partition is slow to the top phase. The maximum values of recovery (57.01 % ± 2.67 %) and PF (4.16 ± 0.06) were reached in the condition with long slug pattern, 35 min of operation, volumetric ratio of 2:1, and a channel diameter of 0.51 mm. The present study provides valuable information for integrating microdevices in a protocol for purifying invertase from S. cerevisiae and other proteins in real systems.

在水基两相系统(ATPS)的萃取过程中使用微型装置的研究已见诸文献多年。然而,流动模式的影响仍有待充分探讨,尤其是在实际样品中。因此,本研究调查了微装置在不同流动模式下回收和部分纯化转化酶的性能。实验中使用了来自酿酒酵母的转化酶和聚乙二醇 1500/硫酸镁体系。除流动模式外,研究还试图通过改变其他操作条件(包括停留时间、容积比和通道直径)来最大限度地提高回收率和纯化因子(PF)值。研究发现,无论停留时间和容积比如何变化,短液滴模式和长液滴模式都比平行模式显示出更好的分离性能。将停留时间从 15 分钟增加到 35 分钟,顶部回收率和 PF 值增加了两倍,这表明 S. cerevisiae 转化酶在顶部相的分配比较缓慢。回收率(57.01 % ± 2.67 %)和 PF 值(4.16 ± 0.06)的最大值出现在长蛞蝓模式、运行 35 分钟、容积比为 2:1、通道直径为 0.51 毫米的条件下。本研究为在实际系统中将微装置集成到纯化酿酒酵母转化酶和其他蛋白质的方案中提供了宝贵的信息。

Formulation and characterization of natural deep eutectic solvents (NADES) for simultaneous phenolics and carotenes extraction from fresh oil palm leaf 天然深共晶溶剂(NADES)的配制和表征,用于从新鲜油棕叶中同时提取酚类和胡萝卜素
IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-08 DOI: 10.1016/j.fbp.2024.07.023

In this study, natural deep eutectic solvents (NADES), comprising choline chloride (ChCl) as hydrogen bond acceptor (HBA) with hydrogen bond donor (HBD) including glucose (Glu), fructose (Fru), xylose (Xyl), xylitol (Xyli), and glycerol (Gly), were formulated and characterized for simultaneous extraction of phenolic compounds (polar) and carotenoids (non-polar) from fresh oil palm leaves (OPL). pH, density, polarity, Fourier Transform Infrared Spectroscopy (FT-IR) and rheological analyses were conducted, with relation to the extraction efficiency achieved via homogenizer-assisted heating and stirring extraction approach. Among the NADES formulations tested, ChCl:Xyl (1:1) displayed the highest total phenolic content (TPC) at 20.23825 mg/g OPL, due to its optimal polarity at 49.4654 kcal mol1 and a viscosity of 23288 mPa.s. The highest total carotenoid content (TCC) was observed in ChCl:Xyli (1:1) at 325.94 µg/g OPL, with a lower polarity at 50.0280 kcal mol1. Despite having similar viscosity and polarity, ChCl:Fru (1:2) with a pH of 5.82 outperformed ChCl:Glu (1:1) with a pH of 6.72 due to enhanced phenolic compound solubility and stability. This study shed light on the potential of NADES, particularly in overcoming the challenge of high moisture content in OPL and other fresh biomasses, which often acted as a barrier during phytonutrients extraction.

本研究配制了天然深共晶溶剂(NADES),其中氯化胆碱(ChCl)为氢键受体(HBA),氢键供体(HBD)包括葡萄糖(Glu)、果糖(Fru)、木糖(Xyl)、木糖醇(Xyli)和甘油(Gly),并对其进行了表征,用于从新鲜油棕叶(OPL)中同时萃取酚类化合物(极性)和类胡萝卜素(非极性)。对 pH 值、密度、极性、傅立叶变换红外光谱(FT-IR)和流变学进行了分析,并将其与通过均质机辅助加热和搅拌萃取方法实现的萃取效率联系起来。在测试的 NADES 配方中,ChCl:Xyl(1:1)的总酚含量(TPC)最高,为 20.23825 mg/g OPL,这是因为其极性最佳,为 49.4654 kcal mol-1,粘度为 23288 mPa.s。尽管粘度和极性相似,但 pH 值为 5.82 的 ChCl:Fru (1:2) 优于 pH 值为 6.72 的 ChCl:Glu (1:1),原因是酚类化合物的溶解度和稳定性都有所提高。这项研究揭示了 NADES 的潜力,尤其是在克服 OPL 和其他新鲜生物质中高水分含量的挑战方面。

A mutant of cellobiose 2-epimerase from Caldicellulosiruptor saccharolyticus (CsCE H356N) was studied for obtaining higher yield of oligosaccharides than by lactose transgalactosylation with Aspergillus oryzae β-galactosidase (AO-βG). Firstly, heterologous production of CsCE H356N was optimized in Luria-Bertani broth and minimal medium. Then, CsCE H356N and AO-βG were used for the synthesis of oligosaccharides varying the sequence of reactions, temperature, and enzyme load. Reactions sequence did not affect the global yield (∼51 %) but modified the product composition. At the best conditions tested, the global yield increased twice with respect to GOS synthesis with AO-βG (25.6 %). When GOS synthesis was followed by the isomerization/epimerization of unreacted lactose, the final product had a higher content of lactulose and GOS than when the reactions sequence was inverted. In the former case lactulose-derived oligosaccharides (fGOS) and fructose were absent, while in the latter the final product mainly contained fGOS, small amounts of GOS, lactulose and fructose. Epilactose content was similar in both sequences.

研究了一种来自糖化钙纤维素酶的纤维生物糖 2-酰亚胺酶突变体(CsCE H356N),它比用黑曲霉β-半乳糖苷酶(AO-βG)进行乳糖转半乳糖化获得更高的低聚糖产量。首先,在 Luria-Bertani 肉汤和最小培养基中优化了 CsCE H356N 的异源生产。然后,使用 CsCE H356N 和 AO-βG 合成寡糖,并改变反应顺序、温度和酶载量。反应顺序不会影响总产率(51%),但会改变产物的组成。在测试的最佳条件下,与用 AO-βG 合成 GOS 相比,总产率提高了一倍(25.6%)。在合成 GOS 后,再对未反应的乳糖进行异构化/表聚化,最终产品中的乳糖和 GOS 含量高于反应顺序颠倒的情况。前者不含乳糖衍生低聚糖(fGOS)和果糖,而后者的最终产物主要含有 fGOS、少量 GOS、乳糖和果糖。两种序列中的表乳糖含量相似。

IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-02 DOI: 10.1016/j.fbp.2024.07.022

A large-capacity radio frequency (RF) rotation heating system was employed in this study to heat dried black fungus, and hot air was used for assistance treatment. The effects of electrode gap, rotation rate and hot air on the uniformity of RF heating of dried black fungus were explored. The optimal heating process parameters were obtained, and the sterilization effect was validated. The results showed that the rotation system could significantly enhance the RF heating uniformity of black fungus (P > 0.05). The optimal heating process for heating a large-capacity (480 g) black fungus was to utilize RF heating assisted by 70 °C hot air with an electrode gap of 175 mm and a rotation rate of 60 rpm, followed by 30 min of heat preservation at 70 °C hot air with a rotation rate of 40 rpm. After the entire sterilization treatment, the heating uniformity index λ of black fungus was reduced to 0.027 ± 0.004, the total plate count decreased by 3 log CFU/g, and the moisture content dropped to below 13 %. The ideal RF heating uniformity and sterilization effect of black fungus were obtained in this study through the simultaneous use of hot air and rotation, providing a theoretical foundation for the application of RF technology in the processing of black fungus.

本研究采用大容量射频(RF)旋转加热系统加热干黑木耳,并使用热空气进行辅助处理。探讨了电极间隙、旋转速度和热空气对射频加热干黑木耳均匀性的影响。获得了最佳加热工艺参数,并验证了灭菌效果。结果表明,旋转系统能显著提高黑木耳的射频加热均匀度(> 0.05)。加热大容量(480 克)黑木耳的最佳加热工艺是利用 70 ℃ 热空气辅助射频加热,电极间隙为 175 毫米,转速为 60 转/分钟,然后在 70 ℃ 热空气中保温 30 分钟,转速为 40 转/分钟。整个灭菌处理后,黑木耳的加热均匀性指数降至 0.027 ± 0.004,菌落总数减少了 3 log CFU/g,水分含量降至 13 % 以下。本研究通过同时使用热风和旋转,获得了理想的射频加热均匀度和黑木耳灭菌效果,为射频技术在黑木耳加工中的应用提供了理论基础。

3-D geometric design of microwaveable food products for optimal heating uniformity based on machine learning-supervised multiphysics models 基于机器学习监督多物理场模型的微波食品三维几何设计,实现最佳加热均匀性
IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-02 DOI: 10.1016/j.fbp.2024.07.017

Multiphysics models can assist in geometric design of frozen microwaveable foods, but the conventional 'parametric-sweeping' strategy is computationally intensive. This study develops an online machine learning (ML)-supervised multiphysics modeling strategy to simultaneously optimize multiple geometrical parameters (e.g., top surface width, top surface length, and the ratio of top-to-bottom dimensions) for optimal microwave heating uniformity. First, one or more paired geometric dimensional parameters and heating uniformity results obtained from multiphysics modeling are used as initial training data for the ML optimization process that integrates Gaussian Process Regression (GPR) and Bayesian optimization. Then, the multiphysics modeling procedure is supervised by an ML process to generate new paired geometry-heating uniformity results to expand the training dataset. The loop of multiphysics modeling and ML optimization is conducted to effectively identify geometry designs with good heating uniformity. Results indicate that the ML-supervised optimization strategy can efficiently identify good geometric designs with low heating uniformity by using much fewer multiphysics models than the parametric sweep approach. The ML-supervised approach also exhibits great robustness, delivering good performance even with small (as little as one model) and randomly selected initial training data. This ML-supervised approach is flexible and can be modified to meet specific needs for broad industrial implementation in the development of microwaveable food.

多物理场模型有助于冷冻微波食品的几何设计,但传统的 "参数扫描 "策略需要大量计算。本研究开发了一种在线机器学习(ML)监督多物理场建模策略,可同时优化多个几何参数(如顶面宽度、顶面长度和顶底尺寸比),以获得最佳微波加热均匀性。首先,多物理场建模获得的一个或多个成对几何尺寸参数和加热均匀性结果被用作集成高斯过程回归(GPR)和贝叶斯优化的 ML 优化过程的初始训练数据。然后,多物理场建模过程在 ML 过程的监督下生成新的成对几何尺寸-加热均匀性结果,以扩展训练数据集。多物理场建模和 ML 优化的循环可有效识别具有良好加热均匀性的几何设计。结果表明,与参数扫描方法相比,多物理场建模和 ML 监督优化策略使用的多物理场模型要少得多,因此能有效识别加热均匀性低的良好几何设计。ML 监督方法还表现出很强的鲁棒性,即使在初始训练数据较小(只有一个模型)和随机选择的情况下,也能提供良好的性能。这种 ML 监督方法非常灵活,可以根据具体需要进行修改,以便在微波食品开发中广泛应用。

Honeycomb porous regenerated cellulose aerogel films with enhanced thermal dissipation for agricultural mulch application 用于农用地膜的蜂窝状多孔再生纤维素气凝胶薄膜具有更强的散热性能
IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-08-02 DOI: 10.1016/j.fbp.2024.07.021

Agricultural films, essential to contemporary agricultural production, are mostly made from non-biodegradable petroleum-based materials. The use of such films, especially in high-temperature environments, contributes to elevated internal temperatures in direct sunlight, adversely affecting crop appearance and quality. In this work, rice straw was used as the raw material to prepare biodegradable chemically crosslinked regenerated cellulose aerogel films (RCAF-CC) by combining physical dissolution regeneration, chemical cross-linking, and freeze-drying. The resulting RCAF-CC is notable for its high middle-infrared emissivity and high solar reflectivity, which significantly aid in thermal dissipation for agricultural mulch by enhancing infrared radiation and solar reflection. Compared to traditional polyethylene films, RCAF-CC, with its superior radiative cooling properties and lower water vapor transport rate, has a significant advantage in the growth trend and survival rate of cherry radishes. It is worth noting that the RCAF-CC achieved the degradation rate of 74.4 % in the 100-day soil burial experiment, and the soybean seeds grown in the degraded soil grew well, showing excellent eco-friendliness. These results show that RCAF-CC can be an alternative source of traditional agricultural films, solving the problems of non-biodegradable and high internal temperatures of the films under direct sunlight.

农用薄膜是当代农业生产的必需品,大多由不可生物降解的石油基材料制成。使用这种薄膜,尤其是在高温环境中使用,会导致在阳光直射下内部温度升高,从而对作物的外观和质量产生不利影响。本研究以水稻秸秆为原料,通过物理溶解再生、化学交联和冷冻干燥等工艺制备了可生物降解的化学交联再生纤维素气凝胶薄膜(RCAF-CC)。生成的 RCAF-CC 具有显著的高中红外辐射率和高太阳反射率,通过增强红外辐射和太阳反射率,大大有助于农用地膜的散热。与传统的聚乙烯薄膜相比,RCAF-CC 具有优越的辐射冷却性能和较低的水蒸气迁移率,在樱桃萝卜的生长趋势和成活率方面具有显著优势。值得注意的是,在 100 天的土壤掩埋实验中,RCAF-CC 的降解率达到了 74.4%,在降解土壤中生长的大豆种子长势良好,表现出优异的生态友好性。这些结果表明,RCAF-CC 可以作为传统农膜的替代来源,解决农膜在阳光直射下不可降解和内部温度过高等问题。

Development of soybean meal protein isolate-based active edible film incorporating bioactive compounds rich kinnow (Citrus reticulata) peel 开发基于豆粕分离蛋白的活性食用薄膜,其中含有丰富的金诺(Citrus reticulata)果皮生物活性化合物
IF 3.5 2区 农林科学 Q2 BIOTECHNOLOGY & APPLIED MICROBIOLOGY Pub Date : 2024-07-31 DOI: 10.1016/j.fbp.2024.07.020

Soybean meal, a reservoir of high-quality protein has been produced in large quantities from the soybean oil processing industry and is mostly used as animal feed. The present work was aimed at the development and characterization of soybean meal protein-based antimicrobial edible film incorporating debittered kinnow peel powder (KPP) and valorizing the underutilized soybean meal protein as well as kinnow peel bioactive compounds. The incorporation of kinnow peel powder reduced the solubility, moisture content and swelling ability of the film than the film prepared without KPP. The addition of KPP up to 20 % (w/w) increased the mechanical and barrier properties of the films. The antioxidant and antimicrobial activity of the film increased by 19 to 20 %, and 75 to 79 %, respectively after the incorporation of KPP. The results of structural characteristics (Fourier transform infrared spectroscopy and X-ray diffraction), and morphology (Scanning electron microscopy) showed the good compatibility of KPP and soybean protein isolate. Thermal properties studied through differential scanning colorimetry showed higher melting temperature of KKP added films as compared to control film. The present work indicated that KPP can be successfully used to develop an active edible film and can be used for storing a variety of food products like cheese, paneer, chocolate bars, cut fruits, etc.

豆粕是优质蛋白质的宝库,由大豆油加工业大量生产,主要用作动物饲料。本研究旨在开发以豆粕蛋白为基础的抗菌可食用薄膜,并对其进行表征,薄膜中加入了脱脂琼果皮粉(KPP),充分利用了豆粕蛋白和琼果皮生物活性化合物。与不添加金诺皮粉的薄膜相比,添加金诺皮粉降低了薄膜的溶解度、含水量和膨胀能力。KPP 的添加量达到 20%(重量比)时,薄膜的机械性能和阻隔性能都有所提高。加入 KPP 后,薄膜的抗氧化和抗菌活性分别提高了 19% 至 20%,以及 75% 至 79%。结构特征(傅立叶变换红外光谱和 X 射线衍射)和形态(扫描电子显微镜)结果表明,KPP 与大豆分离蛋白具有良好的相容性。通过差示扫描比色法研究的热性能表明,与对照薄膜相比,添加了 KKP 的薄膜的熔化温度更高。本研究表明,KPP 可成功用于开发活性食用薄膜,并可用于储存各种食品,如奶酪、paneer、巧克力棒、切好的水果等。
