Traditional Chinese spiced pork is renowned for its appealing flavor, which conventionally relies on substantial amount of spice addition. To achieve more cost-effective production of marinated meat products, this study designed a spice-reduced formulation. 10 key aroma-active compounds were identified in the optimal sensory group. Furthermore, the spice-reduced formulation achieved an 84% reduction in spice usage and retained 70% of key aroma-active compounds, using only 0.2% (w/v) each of peppercorn, cassia, clove and 0.1% (w/v) basil. This work demonstrates a viable strategy for achieving minimalist spice formulation in marinated meat products, offering practical guidance on balancing cost efficiency with sensory authenticity.

传统的中国五花肉以其诱人的味道而闻名,传统的五花肉依赖于大量的香料添加。为了使腌制肉制品的生产更具成本效益,本研究设计了一种减少香料的配方。在最佳感官组中鉴定出10个关键的芳香活性化合物。此外,减少香料的配方减少了84%的香料使用量,保留了70%的关键芳香活性化合物,只使用了0.2% (w/v)的胡椒、桂皮、丁香和0.1% (w/v)的罗勒。这项工作证明了一种可行的策略,以实现极简香料配方的腌制肉制品,提供实用的指导,平衡成本效益与感官的真实性。

Fraudulent substitution of sturgeon caviar with lower-value roe or non-sturgeon eggs poses risks to consumer protection and sturgeon conservation. In this study, a dual-mode loop-mediated isothermal amplification (LAMP) assay was developed for rapid and on-site authentication of sturgeon (Acipenseridae)-derived components in caviar. This assay integrates SYTO-9 real-time fluorescence and hydroxynaphthol blue colorimetry within a closed-tube system. Primers targeting a conserved region of the Acipenser and Huso cytochrome b gene generated a 190-bp amplicon, enabling detection of sturgeon genomic DNA down to 0.1 pg at 64 °C within 10 min, accompanied by a visible sky-blue color change and fluorescence signal. High analytical specificity was demonstrated with no amplification observed from 14 non-Acipenseridae fish samples. Validation using 17 commercial caviar products showed complete agreement with sequencing-based species identification. The simplicity, speed, and closed-tube format of this assay reduce equipment needs and contamination risks, supporting its suitability for regulatory, commercial, and conservation applications.
用价值较低的鱼子或非鲟鱼卵欺诈性替代鲟鱼鱼子酱对消费者保护和鲟鱼保护构成风险。本研究建立了一种双模环介导等温扩增(LAMP)方法,用于鱼子酱中鲟源成分的快速现场鉴定。该检测将SYTO-9实时荧光和羟基酚蓝比色法集成在一个封闭的管系统中。引物靶向Acipenser和Huso细胞色素b基因的保守区域,产生一个190 bp的扩增子,在64 °C下,在10 min内检测到低至0.1 pg的鲟鱼基因组DNA,并伴有可见的天蓝色变化和荧光信号。结果表明,该方法具有较高的分析特异性,在14份非鲟科鱼类样品中无扩增现象。使用17种商业鱼子酱产品进行验证,结果与基于测序的物种鉴定完全一致。该检测的简单性、速度和闭管格式减少了设备需求和污染风险,支持其适用于监管、商业和保护应用。

Flavor esters are extensively used in food and cosmetic industries, yet their sustainable production remains challenging. This study developed a lipase bioreactor through artificial antibody-antigen-directed immobilization for biocatalytic flavor ester synthesis via transesterification. Artificial antigens were prepared by lipase modification with p-nitrobenzaldehyde, while artificial antibodies were synthesized using 2-(4-nitrophenyl)-1,3-dioxolane (acetal-protected p-nitrobenzaldehyde analogue) as template molecules. These components self-assembled into immobilized lipase with 82.24 ± 0.13% immobilization efficiency, 17.59 ± 0.12 mg/g capacity, and 8.81 ± 0.27 U/mg specific activity. Integrating molecular simulations with acyl donor screening, the bioreactor achieved 97.18 ± 0.93% yield for cinnamyl acetate synthesis from cinnamyl alcohol and vinyl acetate. The system demonstrated exceptional continuous catalysis and scalability, confirming industrial translation potential. Successful synthesis of cinnamyl butyrate (86.25 ± 3.34%) and benzyl acetate (90.68 ± 2.25%) further established its versatility as a platform for diverse flavor ester production.

To enhance the iron-chelating activity of blood-derived peptides and streamline the preparation process, goat blood peptides (BP) were prepared via papain-treated hydrolysis, and phosphopeptide‑iron chelate (Fe-P-BP) was further prepared by a one-pot strategy using synergistic phosphorylation modification and endogenous iron chelating reaction. The effect of phosphorylation on iron-chelating capacity was evaluated, while both BP and Fe-P-BP were structurally characterized. Under the optimal condition, the iron chelation rate increased from 10.27% to 64.67% with the iron content of 18.58 mg/L and phosphorylation degree of 8.44 g/L. Structural characterization revealed the successful formation of peptide‑iron chelates primarily through interaction with amino and carboxyl groups. LC-MS/MS identified several novel phosphorylated iron-chelating peptides, with Glu and Asp as the predominant binding sites. In addition, Fe-P-BP exhibited increased particle size and surface roughness, supporting the formation of peptide‑iron chelates. Overall, the current study provides a theoretical reference for effectively enhancing the iron-chelating activity of BP.
为了提高血源肽的铁螯合活性,简化制备工艺,采用木瓜蛋白酶水解制备羊血肽(BP),并采用协同磷酸化修饰和内源性铁螯合反应,采用一锅法制备磷酸肽-铁螯合物(Fe-P-BP)。评估了磷酸化对铁螯合能力的影响,并对BP和Fe-P-BP进行了结构表征。在最佳条件下,铁螯合率从10.27%提高到64.67%,铁含量为18.58 mg/L,磷酸化程度为8.44 g/L。结构表征表明,肽铁螯合物主要通过与氨基和羧基的相互作用成功形成。LC-MS/MS鉴定了几个新的磷酸化铁螯合肽,以Glu和Asp为主要结合位点。此外,Fe-P-BP的颗粒尺寸和表面粗糙度增加,支持肽铁螯合物的形成。综上所述,本研究为有效提高BP的铁螯合活性提供了理论参考。

Microbial spoilage and excessive pesticide residues pose significant health risks in fresh fruits. This study introduces a concept of active elimination of pesticide residues and microbes on fruit by cellular respiration-stimulated ROS release. For this aim, the biocompatible Zn@metal-organic frameworks (Zn@MOFs) are constructed to autonomously produce reactive oxygen species without light activation, driven by ambient oxygen and moisture activated through fruit cellular respiration. The in situ produced ROS concurrently enhances broad-spectrum antimicrobial activity towards fungi and bacteria. With the help of pectin, the Zn@MOFs could form a uniform and robust protective layer on fruit, adsorb pesticides on the fruit surface, and significantly extend the freshness of non-climacteric fruits and climacteric fruits. Metabolomics analysis reveals that such active coating suppresses key ripening-associated metabolic pathways, including amino acid metabolism and ABC transporter activity. The coating offers a promising, innovative approach for developing next-generation active food packaging.
新鲜水果的微生物腐败和过量农药残留对健康构成重大威胁。本研究介绍了通过细胞呼吸刺激活性氧释放来主动清除水果上的农药残留和微生物的概念。为此,构建了生物相容性Zn@metal-organic框架(Zn@MOFs),在没有光激活的情况下自主产生活性氧,由周围的氧气和水分驱动,通过水果细胞呼吸激活。原位产生的活性氧同时增强了对真菌和细菌的广谱抗菌活性。Zn@MOFs在果胶的帮助下,可以在果实表面形成均匀而坚固的保护层,吸附果实表面的农药,显著延长非更年期水果和更年期水果的新鲜度。代谢组学分析表明,这种活性包衣抑制了关键的成熟相关代谢途径,包括氨基酸代谢和ABC转运蛋白活性。该涂层为开发下一代活性食品包装提供了一种有前途的创新方法。

Authentication of honey according to its botanical origin is essential for quality control. Traditional melissopalynological methods are time-consuming and subjective, motivating the search for faster alternatives. In this work, HPLC-UV protein fingerprinting approach was developed to classify honeys of different floral origins. Previously, proteins were isolated and preconcentrated using a gold nanoparticle-assisted solid-phase extraction. 61 Spanish honey samples from chestnut, heather, and thyme origins were studied where 27 different bee-derived proteins were identified. Distinct protein fingerprint patterns were observed where heather showed the most diverse SPE protein fingerprint, chestnut honey a more balanced distribution and thyme honey displayed higher levels of stress-related proteins. A linear discriminant analysis model was developed using sum-normalized protein abundances. The model was trained with 40 samples and externally validated with 21 independent samples, achieving 100% correct classification. The results demonstrate that bee-origin proteins reflect floral influences and can serve as stable biomarkers for honey authentication.
根据蜂蜜的植物来源进行鉴定对质量控制至关重要。传统的同源学方法耗时且主观,促使人们寻找更快的替代方法。本研究采用HPLC-UV蛋白指纹图谱方法对不同花源的蜂蜜进行分类。以前,蛋白质是用金纳米颗粒辅助固相萃取分离和预浓缩的。研究人员对61份来自栗子、石南花和百里香的西班牙蜂蜜样本进行了研究,发现了27种不同的蜜蜂衍生蛋白质。在不同的蛋白质指纹图谱中,石楠花显示出最多样化的SPE蛋白质指纹图谱,栗子蜜分布更平衡,百里香蜜显示出更高水平的压力相关蛋白质。利用蛋白质丰度和归一化建立了线性判别分析模型。模型训练了40个样本,外部验证了21个独立样本,分类准确率达到100%。结果表明,蜂源蛋白反映了花的影响,可以作为蜂蜜鉴定的稳定生物标志物。

Egg is one of the Big-Nine allergenic foods in the U.S., and accurate detection of its allergenic proteins is critical for food safety. Chicken serum albumin (CSA, Gal d 5), an allergen found in egg yolk, chicken meat, and avian-derived materials, remains under-detected in food products. This study aimed to characterize CSA and develop a quantitative Western blot (qWB) assay for the detection of CSA. After characterization, (1) high temperature (>69.61 °C) decreased CSA extractability, (2) in vitro allergenicity was detected by human plasma, and (3) CSA was verified in egg white. A monoclonal antibody 3H4E9 was characterized as specific to poultry serum albumin. The optimized qWB assay exhibited good selectivity (specific to poultry species), working range (0.3–20 ppm), and sensitivity (ppm level). This assay enables sensitive and reliable CSA detection on food contact surfaces, facilitating risk assessment of undeclared egg yolk residues and improving food safety management practices.
鸡蛋是美国九大致敏食品之一,准确检测其致敏蛋白对食品安全至关重要。鸡血清白蛋白(CSA, Gal d 5)是一种在蛋黄、鸡肉和禽类衍生材料中发现的过敏原,在食品中仍未被检测到。本研究旨在对CSA进行表征,并建立CSA的定量Western blot (qWB)检测方法。经鉴定,(1)高温(>69.61 °C)降低了CSA的可提取性,(2)人血浆检测体外致敏性,(3)在蛋清中验证了CSA。一种单克隆抗体3H4E9对家禽血清白蛋白具有特异性。优化后的qWB法具有良好的选择性(对禽类品种有特异性)、工作范围(0.3-20 ppm)和灵敏度(ppm水平)。该方法能够对食品接触面进行敏感可靠的CSA检测,促进未申报蛋黄残留物的风险评估,提高食品安全管理水平。
