The microencapsulation of essential oils by complex coacervation technology has attracted considerable attention. This paper deals with the preparation of gelatin-chitosan microcapsules through dual cross-linking using transglutaminase (TGase) and tannic acid (TA). Lemon essential oil (LEO) was successfully encapsulated with 82.5 % encapsulation efficiency. Compared to single cross-linking microcapsules (TG), dual cross-linking microcapsules (TG-TA) exhibit superior thermal stability and swell stability. In vitro release studies demonstrated that TG-TA exhibited better controlled-release behavior with a longer duration of action. Meanwhile, the lipid oxidation of TG-TA was 1.45 mg MDA/kg that of control group was 2.23 mg MDA/kg which showed their excellent antioxidant effects. Moreover TG-TA have higher antibacterial rate, more inhibition zone diameters and better effect for preventing the growth of total viable count than TG and LEO. This study has theoretical implications for the use of TG-TA ideal carriers for protecting various active substances, thus facilitating their applications in food preservation.
采用复合共凝胶技术对精油进行微胶囊化已引起广泛关注。本文探讨了使用转谷氨酰胺酶(TGase)和单宁酸(TA)通过双重交联制备明胶-壳聚糖微胶囊的方法。柠檬精油(LEO)被成功封装,封装效率为 82.5%。与单交联微胶囊(TG)相比,双交联微胶囊(TG-TA)具有更好的热稳定性和膨胀稳定性。体外释放研究表明,TG-TA 的控释性能更好,作用时间更长。同时,TG-TA 的脂质氧化作用为 1.45 毫克 MDA/千克,而对照组为 2.23 毫克 MDA/千克,这表明它们具有出色的抗氧化效果。此外,与 TG 和 LEO 相比,TG-TA 具有更高的抗菌率、更大的抑菌区直径和更好的防止总存活数增长的效果。这项研究对使用 TG-TA 作为保护各种活性物质的理想载体,从而促进其在食品保鲜中的应用具有理论意义。

During wine ageing, tannins could react with sulfur dioxide to form sulfonated flavanols which are anticipated to alter tannin binding to proteins contributing to the reduction of astringency during ageing. Previous studies have identified or quantified monomeric and dimeric sulfonated flavanols in aged wines, but the evolution of sulfonated tannins has been lacking. Here, we quantified sulfonated tannins in three Washington state vineyards over a 20-year period, employing targeted LC-QToF analysis. Analysis of 24 wines revealed a systematic trajectory of sulfonated tannins over 20 years. Sulfonated monomers rose consistently with wine age, becoming the dominant form of sulfonated products in all samples at the 20-year mark. Concurrently, there was a decline in native tannins and sulfonated oligomers, suggesting a process of acid-catalyzed depolymerization of native tannins followed by sulfonation via reaction with sulfur dioxide. Future work is needed to understand the stability of sulfonated tannins and their impact on wine astringency.
在葡萄酒的陈酿过程中,单宁可能会与二氧化硫发生反应,形成磺化黄烷醇,从而改变单宁与蛋白质的结合,减少陈酿过程中的涩味。以前的研究已经确定或量化了陈酿葡萄酒中的单体和二聚磺化黄烷醇,但对磺化单宁的演变还缺乏研究。在此,我们采用针对性的 LC-QToF 分析方法,对华盛顿州三个葡萄园 20 年间的磺化单宁进行了量化。对 24 款葡萄酒的分析表明,20 年间磺化单宁的变化轨迹是系统性的。磺化单体随着酒龄的增加而持续上升,在 20 年的时间里成为所有样品中磺化产品的主要形式。与此同时,原生单宁和磺化低聚物的含量有所下降,这表明原生单宁在酸催化下发生了解聚,然后通过与二氧化硫的反应发生了磺化。要了解磺化单宁的稳定性及其对葡萄酒涩味的影响,还需要今后的工作。

Semiconductor heterojunction with functional integration can be used as an excellent matrix for the ultrasensitive detection of bisphenol A (BPA) with low molecular affinity. Here, a simple, low-cost and sensitive surface-enhanced Raman scattering (SERS) strategy using g-C3N4/TiO2 heterojunction as substrate was presented for detection of BPA residues in foods. The g-C3N4/TiO2 achieved specific chemisorption for target analyte by the formation of intermolecular H-bond between g-C3N4 and BPA. And, a high-efficiency carrier separation in TiO2 induced by heterostructure could be achieved for charge transfer between the substrate and molecule by a “donor-bridge-acceptor” charge-transfer mode. Due to the synergistic/collaborative contributions of two monomers in heterojunction, the SERS enhancement factor was as high as 3.77 × 107. The detection limit of BPA residues in foods (milk, juice and drinking water) was as low as 10−9 mol·L−1, far below the EU standard. The developed substrate also exhibited excellent stability and anti-interference capability.

Supercritical carbon dioxide (SCCD) has been studied for its effectiveness in preserving vegetables, but most research has focused on overall changes in the total phenolic, carotenoid and sugar contents. However, the detailed changes in individual nutrients during storage, as well as their relationship, remain largely unexplored. Herein, in this work, high-performance liquid chromatography (HPLC) was used to analyze the variations in individual carotenoids and sugars in SCCD-treated carrots and pumpkins during 21 days of storage. The results demonstrated that SCCD effectively inhibited microbial growth, and maintained the low levels of polyphenol oxidase (PPO) and peroxidase (POD) activity during storage. SCCD also deferred the degradation of carotenoid profile and phenolic compounds. Additionally, SCCD accelerated the hydrolysis of sucrose content while postponing the reduction of glucose and fructose. In summary, the SCCD technique could delay the quality deterioration of fresh-cut vegetables, preserving them with minimal quality changes.
人们一直在研究超临界二氧化碳(SCCD)在保存蔬菜方面的功效,但大多数研究都集中在总酚类、类胡萝卜素和糖含量的整体变化上。然而,对于贮藏过程中单个营养成分的详细变化以及它们之间的关系,大部分研究仍未进行。因此,本研究采用高效液相色谱法(HPLC)分析了经 SCCD 处理的胡萝卜和南瓜在 21 天贮藏期间类胡萝卜素和糖类的变化。结果表明,SCCD 能有效抑制微生物的生长,并在贮藏期间保持低水平的多酚氧化酶 (PPO) 和过氧化物酶 (POD) 活性。SCCD 还能延缓类胡萝卜素和酚类化合物的降解。此外,SCCD 加快了蔗糖含量的水解,同时推迟了葡萄糖和果糖的还原。总之,SCCD 技术可以延缓鲜切蔬菜的质量劣化,在保存蔬菜的同时将质量变化降到最低。

This study investigates the integration of Broadband Cavity Enhanced Absorption Spectroscopy (BBCEAS) with High-Performance Liquid Chromatography (HPLC) to detect synthetic antioxidants; BHA, BHT, and TBHQ in the deep-UV region below 300 nm. The research addresses the need for more sensitive and cost-effective detection methods in HPLC systems, particularly for low analyte concentrations, by exploring BBCEAS as a superior alternative to conventional detectors that often fall short in sensitivity. The sensitivity of the HPLC-BBCEAS system is assessed by calculating the minimum detectable change in the absorption coefficient (αmin) and comparing with those obtained using conventional HPLC and single-wavelength HPLC-CRDS methods. The findings demonstrate that the HPLC-BBCEAS system achieves αmin values of 1.8 × 10−5 cm−1 for BHA, 2.8 × 10−5 cm−1 for BHT, and 1.9 × 10−5 cm−1 for TBHQ at 280 nm, with Limits of Detection (LOD) and Quantification (LOQ) up to 30 times lower than conventional HPLC systems.
本研究探讨了如何将宽带腔体增强吸收光谱(BBCEAS)与高效液相色谱法(HPLC)相结合,以检测 300 纳米以下深紫外区的合成抗氧化剂 BHA、BHT 和 TBHQ。这项研究旨在满足高效液相色谱系统对灵敏度更高、成本效益更高的检测方法的需求,尤其是在检测低浓度分析物时,将 BBCEAS 作为灵敏度通常较低的传统检测器的优越替代品。HPLC-BBCEAS 系统的灵敏度是通过计算吸收系数的最小可检测变化 (αmin),并与使用传统 HPLC 和单波长 HPLC-CRDS 方法获得的结果进行比较来评估的。研究结果表明,HPLC-BBCEAS 系统在 280 纳米波长下的 BHA αmin 值为 1.8 × 10-5 cm-1,BHT 为 2.8 × 10-5 cm-1,TBHQ 为 1.9 × 10-5 cm-1,检测限 (LOD) 和定量限 (LOQ) 比传统 HPLC 系统低 30 倍。

Rapid detection of corn moisture content(MC) during maturity is of great significance for field cultivation, mechanical harvesting, storage, and transportation management. However, cumbersome operation, time-consuming and labor-intensive operation were the bottleneck in the traditional drying process and dielectric parameter method. Thus, to overcome the above problems, a rapid detection method for corn MC based on improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN) combined with temporal convolutional network-bidirectional gated recurrent unit (TCN-BiGRU) model. First, based on the 405 groups of NIR spectral data of corn seeds, the crested Porcupine Optimizer (CPO) algorithm was used to optimize ICEEMDAN to reduce the noise of the original spectral data. Then the Chaotic-Cuckoo Search (CCS) algorithm was applied to extract 203 characteristic wavenumbers from the original spectrum, which were input into the constructed TCN-BiGRU network model to realize corn MC detection. Finally, the CPO-ICEEMDAN-CCS-TCN-BiGRU corn MC classification detection model was constructed. The result showed that the model accuracy was 97.54 %, which was 9.22 %, 5.58 %, 2.34 %, 4.74 %, and 5.94 % higher than those of convolutional neural networks (CNN), long short-term memory networks (LSTM), temporal convolutional network (TCN), partial least squares (PLS), and support vector machine (SVM) models, respectively. The research results can provide a reliable basis for improving corn yield, quality and economic benefits.
快速检测玉米成熟期的水分含量(MC)对田间种植、机械收获、储藏和运输管理具有重要意义。然而,操作繁琐、耗时耗力是传统烘干工艺和介电参数法的瓶颈。因此,为了克服上述问题,一种基于自适应噪声的改进型完全集合经验模式分解(ICEEMDAN)与时序卷积网络-双向门控递归单元(TCN-BiGRU)模型相结合的玉米 MC 快速检测方法应运而生。首先,基于 405 组玉米种子的近红外光谱数据,使用波峰豪猪优化器(CPO)算法对 ICEEMDAN 进行优化,以降低原始光谱数据的噪声。然后采用混沌布谷鸟搜索(CCS)算法从原始光谱中提取 203 个特征波长,并将其输入构建的 TCN-BiGRU 网络模型,以实现玉米 MC 检测。最后,构建了 CPO-ICEEMDAN-CCS-TCN-BiGRU 玉米 MC 分类检测模型。结果表明,该模型的准确率为 97.54 %,分别比卷积神经网络(CNN)、长短期记忆网络(LSTM)、时序卷积网络(TCN)、偏最小二乘法(PLS)和支持向量机(SVM)模型的准确率高 9.22 %、5.58 %、2.34 %、4.74 % 和 5.94 %。研究成果可为提高玉米产量、质量和经济效益提供可靠依据。

Mango bagasse (MB) is a (poly)phenols and fiber (DF)-rich agroindustrial by-product exhibiting health-beneficial properties. This research aimed to design and characterize an MB-added confection and evaluate its prebiotic effect in vitro. A sensory analysis involving 51 children was conducted to select the most accepted formulation. Nine formulations (3k factorial design) were screened through texture profile analysis to select an MBC formulation that was hydrated (1:4 and 1:5 MBC:water) to reduce its hardness, where 1:4 was chosen. Compared to MB, 1:4 formulation showed a higher protein (+1.20-fold) but less DF (−0.62-fold). The confections contained gallic acid, mangiferin, quercetin, and (+)-catechin (234.82–479.69 g/100 g sample) but displayed a lower in vitro accessibility than those from MB. Selected bacterial strains exhibited fermentative activity using MBC as a substrate, which was even better than using MB fiber-only. The results showed the potential of MB to DF and (poly)phenol-rich confections with prebiotic potential.
芒果渣(MB)是一种富含(多)酚和纤维(DF)的农用工业副产品,具有有益健康的特性。本研究旨在设计一种添加了芒果渣的糖果并确定其特性,同时在体外评估其益生效果。对 51 名儿童进行了感官分析,以选出最受欢迎的配方。通过质构分析筛选了九种配方(3k 因式设计),选出了一种水合(1:4 和 1:5 水合甲基溴:水)的甲基溴配方,以降低其硬度,其中选择 1:4。与甲基溴相比,1:4 配方的蛋白质含量更高(+1.20 倍),但 DF 含量较低(-0.62 倍)。糖果中含有没食子酸、芒果苷、槲皮素和 (+)- 儿茶素(234.82-479.69克/100克样品),但与甲基溴相比,其体外易得性较低。选定的细菌菌株以 MBC 为底物表现出发酵活性,甚至优于仅使用甲基溴纤维的情况。研究结果表明,甲基溴具有生产 DF 和富含(多)酚的糖果的潜力,并具有益生元潜力。

Lactarius hatsudake Tanaka is a popular edible mushroom known for its delicious flavor and health benefits. Its polysaccharides (LHP) exhibit significant bioactivity, but their application is limited due to uncertainties in digestion. This study used in vitro simulated models to explore the dynamic changes of LHP during the digestive and fermentation process and validated them through mouse models. Results revealed that LHP cannot be digested by the simulated digestive system, but is primarily degraded into fatty acids by gut microbes, accompanied by reductions in molecular weight, carbohydrate content, and pH. Additionally, LHP promotes the proliferation of beneficial bacteria (Faecalibacterium, Bifidobacterium, Lactobacillus, etc.), while inhibiting harmful bacteria (Escherichia and Shigella). Metabolite analysis in serum indicated that LHP can regulate amino acid and lipid metabolism, enhancing overall health. These findings provide a theoretical foundation for developing LHP as a potential prebiotic, highlighting its considerable promise for disease prevention through improved intestinal health.
田中乳菇(Lactarius hatsudake Tanaka)是一种广受欢迎的食用菌,因其味道鲜美、有益健康而闻名。其多糖(LHP)具有显著的生物活性,但由于消化过程中的不确定性,其应用受到限制。本研究使用体外模拟模型来探索 LHP 在消化和发酵过程中的动态变化,并通过小鼠模型进行验证。结果发现,LHP 不能被模拟消化系统消化,而主要被肠道微生物降解成脂肪酸,同时分子量、碳水化合物含量和 pH 值也会降低。此外,LHP 还能促进有益细菌(粪杆菌、双歧杆菌、乳酸杆菌等)的增殖,同时抑制有害细菌(埃希氏菌和志贺氏菌)。血清中的代谢物分析表明,LHP 可调节氨基酸和脂质代谢,增强整体健康。这些发现为将 LHP 开发为潜在的益生元提供了理论基础,突出了其通过改善肠道健康来预防疾病的巨大前景。

Sweetness is a crucial taste component in Baijiu. However, comprehensive research on the sweetness of Baijiu remains limited, and traditional methods for flavor analysis are not well-suited for identifying the sweet compounds. To address this, a multi-stage molecular distillation method, combined with molecular sensory science, was developed to more effectively and scientifically analyze the key sweet compounds in Baijiu. The recovery rates of samples and compounds were 93.8 % ~ 98.3 % and 81.6 % ~ 118.3 %. 15 important compounds with a taste dilution factor (TD) value ≥64 were identified through gas chromatography–mass spectrometry (GC–MS) combined with taste dilution analysis (TDA). By calculating their taste activity values (TAV), 10 primary sweet compounds with TAV ≥1 were determined. Further taste recombination and omission experiments confirmed that ethyl hexanoate, ethyl heptanoate, ethyl octanoate, ethyl 2-methylbutyrate, 1-butanol, phenethyl alcohol, and ethyl acetate contribute significantly to Baijiu's sweetness and are identified as the key sweet compounds.
甜味是白酒的重要口感成分。然而,对白酒甜味的全面研究仍然有限,传统的风味分析方法也不适合鉴定甜味化合物。为此,我们开发了一种多级分子蒸馏法,并结合分子感官科学,以更有效、更科学地分析白酒中的主要甜味化合物。样品和化合物的回收率分别为 93.8 % ~ 98.3 % 和 81.6 % ~ 118.3 %。通过气相色谱-质谱(GC-MS)结合味觉稀释分析(TDA),确定了 15 种味觉稀释因子(TD)值≥64 的重要化合物。通过计算它们的味觉活性值(TAV),确定了 10 种 TAV≥1 的初级甜味化合物。进一步的味觉重组和省略实验证实,己酸乙酯、庚酸乙酯、辛酸乙酯、2-甲基丁酸乙酯、1-丁醇、苯乙醇和乙酸乙酯对白酒的甜味有显著贡献,被确定为主要甜味化合物。
