This review addresses the challenges in valorizing walnut meal, a by-product of walnut oil extraction, by outlining its key bioactive constituents—proteins/active peptides, polysaccharides, and phenolic compounds—and their health benefits. It examines emerging green processing strategies, including mixed-strain solid-state fermentation, microbe-enzyme synergistic fermentation, and integrated multi-technology approaches. The article also discusses the evolution of efficacy assessment from conventional cellular and animal models toward human biomimetic platforms such as organoids and organs-on-chips, which offer more physiologically relevant models for elucidating functional mechanisms. In contrast to existing reviews focusing on isolated components or conventional techniques, this work constructs an integrated framework spanning from “green synergistic processing” to “human biomimetic evaluation.” It aims to accelerate the translation of walnut-derived bioactive compounds into functional foods and pharmaceuticals, promoting comprehensive, high-value utilization of walnut resources.

This study evaluated the effectiveness of pH indicator patches in monitoring the quality of Beluga fish (Huso huso) stored at 4 °C for 3, 7, and 14 days, assessing changes in chemical, microbial, and sensory properties. Three polymer solutions (G0, G1, G2) were used to create nanofibrous patches via electrospinning. The fish were stored, and chemical analyses (peroxide value (PV) and total volatile basic nitrogen (TVB-N)), sensory evaluation (texture, color, odor), and microbial counts (psychrophilic and thermophilic bacteria) were conducted. On day 3, G0 and G1 exhibited clearer color changes compared to G2, with G1 showing sharper shifts. By day 14, G0 and G1 exhibited a slight decrease in the a* value, whereas G2 showed greater variation. PV and TVB-N increased significantly, indicating oxidative spoilage and protein degradation. Sensory evaluation revealed a decline in color, odor, texture, and acceptability. The pH-sensitive patches effectively monitored fish quality, but further optimization is needed.

The present study was designed to determine the composition, emulsion properties and microencapsulation efficiency of Zanthoxylum oil bodies (ZOBs) at pH values of 6.3 and 11.0, employing soy protein isolate (SPI) and maltodextrin (MD) as wall materials. The findings indicated that pH 11.0-ZOBs exhibited improved emulsion stability and encapsulation efficiency was higher compared to pH 6.3-ZOBs. Across pH 11.0 and pH 6.3, the optimal SPI:MD ratios (1:3 and 1:4, respectively) resulted in increased encapsulation yields (86.83% and 81.58%, respectively) and the least surface oil. The combined effects of pH and wall material composition significantly affected emulsion stability, particle size and solubility (p < 0.05) with pH 11.0-ZOBs showing the greatest thermal and oxidative stability. Such correlations verify the significance of pH and wall material optimization for the isolation and microencapsulation OBs, providing insights to enhance the stability and functionality of encapsulated oils.

This study investigated how high hydrostatic pressure (HHP) modulates the structural and functional properties of whey protein isolate (WPI) complexes with Malvidin-3-O-6-[acrylic acid-(2-hydroxy,4-carboxy-cyclohexanol) ester]-guaiacol (MV3ACEC). HHP at 350 MPa maximized the binding ratio (78.41 ± 0.94%) and thermal stability (denaturation temperature: 123.76 °C) of WPI-MV3ACEC, while reducing particle size (237 nm) and enhancing system stability (zeta potential: 12.7 mV). Structural analyses revealed HHP-induced conformational changes in WPI-MV3ACEC, including decreased α-helix and increased β-sheet content. Molecular simulations confirmed optimal binding affinity (−7.8 kcal/mol) at 350 MPa, dominated by van der Waals forces. HHP-treated complexes retained antioxidant activity and improved gastrointestinal stability, with MV3ACEC retention reaching 38.17% ± 0.86% post-intestinal digestion. These findings elucidate the binding mechanisms between WPI and MV3ACEC under HHP, providing novel insights for designing functional dairy products.

Sequential roasting is a unique technology for processing of Lu’an Guapian green tea. The chemical base and the mechanisms underpinning roasting-induced flavor and aroma changes are not fully understood. Here, variations in volatiles, catechins, and free amino acids were quantitatively measured, four epi-catechins and seven amino acids were significantly decreased, while gallocatechin and four phenylpropanoid volatiles (benzaldehyde, phenyl acetaldehyde, benzyl nitrile, and indole) were significantly increased. Modeling experiments suggest that benzyl alcohol, benzaldehyde, and phenyl acetaldehyde could be derived from phenylalanine pyrolysis and phenylalanine/glucose Maillard reaction, while indole could be derived from tryptophan pyrolysis and tryptophan/glucose Maillard reaction. In addition, phenyl acetaldehyde could be synthesized through tyrosine/glucose Maillard reaction. Gallocatechin, epigallocatechin, and gallocatechin gallate showed inhibition or activation toward aromatic amino acid pyrolysis or Maillard reaction in an amino acid- and gallocatechin isomer-specific manner. This study provided mechanistic insights about phenylpropanoid volatile synthesis and the roles of gallocatechin isomers during sequential roasting of Lu’an Guapian green tea.

Lactiplantibacillus plantarum NCU0011259 was employed to ferment lychee pulp, with a systematic investigation of the flavor and bioactivities of the resulting product in this study. Results showed that fermentation with this strain increased organic acids, reduced sugars and bitter amino acids to refine taste, and elevated favorable alcohols/ethers while lowering off-flavor aldehydes to optimize the aroma profile. Moreover, fermentation induced profound metabolic remodeling, remarkably enhancing the in vitro antioxidant capacity and inhibitory activities against pancreatic lipase, α-glucosidase, and α-amylase. Correspondingly, the total polyphenol content increased from 321.94 μg/g to 663.75 μg/g, accompanied by notable enrichment of free polyphenols (e.g., (−)-gallocatechin) and restructuring of bound polyphenol fractions. Correlation analysis identified key polyphenols (e.g., m-coumaric acid, ferulic acid, tiliroside) as core components underlying enhanced antioxidant and digestive enzyme inhibitory activities. This study validates L. plantarum NCU0011259's excellent fermentation performance and lays a solid theoretical basis for developing high-quality fermented lychee functional foods.
本研究采用植物乳杆菌NCU0011259对荔枝果肉进行发酵，对发酵产物的风味和生物活性进行了系统的研究。结果表明，该菌株通过增加有机酸、还原糖和苦味氨基酸来改善口感，增加有利醇/醚，降低异味醛来优化香气。此外，发酵诱导了深刻的代谢重塑，显著提高了体外抗氧化能力和对胰脂肪酶、α-葡萄糖苷酶和α-淀粉酶的抑制活性。相应的，总多酚含量从321.94 μg/g增加到663.75 μg/g，游离多酚（如(−)-没食子儿茶素）显著富集，结合多酚组分重组。相关分析发现，关键多酚（如间香豆酸、阿魏酸、铁力苷）是增强抗氧化和消化酶抑制活性的核心成分。本研究验证了L. plantarum NCU0011259优良的发酵性能，为开发优质发酵荔枝功能食品奠定了坚实的理论基础。

The effects of lactic acid bacteria fermentation, extrusion puffing, and germination on the starch structure, processing properties, and bioactive components of brown rice flour (BRF) were compared. The results showed that the above methods slowed the starch digestibility, lowered the glycemic index (GI), improved processing characteristics, and reduced the content of the antinutritional factor phytic acid. Among them, the fermentation by Pediococcus pentosaceus JS35 and Lactobacillus acidophilus decreased the starch hydrolysis rate C∞ of BRF from 72.36% to 47.23%, reduced the GI value to 51.56. Additionally, the relative crystallinity, gelatinization enthalpy, total starch and phytic acid content of the fermented BRF decreased by 69.72%, 61.36%, 45.01% and 37.33%, respectively. The content of γ-aminobutyric acid and amylose in fermented BRF increased by 195.5% and 108.45%, respectively. These results demonstrated that the fermentation was potential method for the development of whole grain brown rice products and low-GI foods.

Turmeric (Curcuma longa L.) is a popular natural food ingredient worldwide, known for its remarkable antioxidant, anticancer, and cardiovascular protective properties. It holds significant economic value and is an important crop in many tropical and subtropical countries. Sichuan, China, is a historical and primary cultivation region for turmeric, with a cultivation history spanning over a thousand years. However, the local turmeric market has been greatly impacted by imported turmeric, and the crop is also prone to diseases that can reduce yield. As a result, local farmers in Shuangliu have shown decreasing interest in cultivating turmeric. To address this issue, our research team analyzed the HBS turmeric cultivar, which has been selectively bred in the Shuangliu region for years, and compared it with the mainstream Chinese cultivar, CJH. Both cultivars have their respective advantages in terms of yield and quality: CJH has higher curcumin and essential oil content, while HBS has a significantly higher yield. Widely targeted metabolomics analysis was conducted using both liquid chromatograph-mass spectrometer (LC-MS) and gas chromatograph-mass spectrometer (GC–MS) platforms. The LC-MS platform detected 2206 compounds, and the GC–MS platform detected 1521 compounds. The major differential compounds between the two cultivars were found in categories such as diphenylheptanes, gingerols, flavonols, tannins, and terpenoids. Compared to CJH, HBS showed a higher concentration of gingerols and tannins. Additionally, HBS had a flavor profile that leaned more toward sweet, fruity, and green notes, with a milder spicy taste, making it more palatable. Based on these findings, HBS exhibits substantial potential for food and health product development and can be cultivated as food use instead of medicinal use. This research is of great significance for the development of turmeric in Sichuan, as well as for improving the economic income of local farmers. Furthermore, it lays an important foundation for the future breeding of food use turmeric varieties.
姜黄（Curcuma longa L.）是一种全球流行的天然食品成分，以其卓越的抗氧化、抗癌和心血管保护特性而闻名。它具有重要的经济价值，是许多热带和亚热带国家的重要作物。中国四川是历史悠久的姜黄主产区，有着上千年的栽培历史。然而，当地的姜黄市场受到进口姜黄的极大影响，而且作物也容易出现减产的疾病。因此，双流当地农民对种植姜黄的兴趣逐渐下降。为解决这一问题，课题组对在双流地区选育多年的HBS姜黄品种进行了分析，并与中国主流品种CJH进行了比较。两个品种在产量和品质上各有优势：CJH姜黄素和精油含量较高，HBS产量显著高于CJH。采用液相色谱-质谱（LC-MS）和气相色谱-质谱（GC-MS）平台进行广泛靶向代谢组学分析。LC-MS平台检测到2206种化合物，GC-MS平台检测到1521种化合物。两个品种之间的主要差异化合物是二苯基庚烷、姜辣素、黄酮醇、单宁和萜类化合物。与CJH相比，HBS显示出更高的姜辣素和单宁浓度。此外，哈佛商学院的口味特征更倾向于甜味、水果味和绿色调，辛辣味较轻，使其更美味。基于这些发现，HBS显示出食品和保健产品开发的巨大潜力，可以作为食品用途而不是药用。本研究对发展四川地区的姜黄产业，提高当地农民的经济收入具有重要意义。为今后食用用姜黄品种的选育奠定了重要的基础。

Based on these findings, HBS exhibits substantial potential for food and health product development and can be cultivated as food use instead of medicinal use. This research is of great significance for the development of turmeric in Sichuan, as well as for improving the economic income of local farmers. Furthermore, it lays an important foundation for the future breeding of food use turmeric varieties.</div></div>","PeriodicalId":12334,"journal":{"name":"Food Chemistry: X","volume":"34 ","pages":"Article 103533"},"PeriodicalIF":8.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146075631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drying critically impacts protein structure and function. Sea buckthorn peptide industrialization is challenged by preserving structural integrity and bioactivity during drying, as thermal and mechanical stresses alter protein properties and flavor. Systematic comparisons of drying methods for sea buckthorn protein hydrolysates are lacking. This study evaluated vacuum freeze-drying (VFD), Spray-drying (SD), and microwave vacuum drying (MVD) effects on sea buckthorn protein hydrolysates (SBP) structure, antioxidant capacity, and flavor. VFD-SBP demonstrates exceptional antioxidant properties (DPPH and ABTS radical scavenging rates of 72.34 ± 4.32% and 81.56 ± 2.99%), augmented amino acid retention capabilities, and enhanced thermal stability, respectively. SD-SBP possessed richer volatiles with a roasted nutty aroma, while VFD-SBP better preserved heat-sensitive flavors, yielding a pea-like odor. In contrast to prior studies limited to single methods or parameters, this work provides a comprehensive multidimensional comparison, and offers theoretical support for the high-value utilization of sea buckthorn protein hydrolysates in functional foods and nutraceuticals.

This study aimed to investigate the effect of various sweeteners on the development of Maillard reaction products in wheat cookies. Cookies prepared using pure sugars (fructose, glucose, dextrose, sucrose), maltex, brown cane sugar, coconut sugar, xylitol, erythritol, maple syrup and agave syrup, acacia honey and meadow honey, apricot jam and pumpkin jam and stevia extract were baked at 180 °C for 7, 10 and 13 min. The levels of acrylamide and 5-hydroxymethylfurfural (HMF), as well as color were monitored in these cookies. At 180 °C, acrylamide was detected at all baking times, reaching a final concentration of 592.1 μg/kg up to 2000.3 and 2063.7 μg/kg after 13 min of baking in cookies containing brown cane sugar, which comprises 99.19% sucrose, and coconut sugar i.e. pumpkin jam, respectively. The highest HMF accumulation was a consequence of sucrose replacement with acacia honey and meadow honey. In cookies with sugar alcohols and stevia, HMF was not detected.
