A unique combination of LP-disaccharide interactions was employed. Spectroscopic technologies, which include fluorescence spectra, ultraviolet spectra, and Fourier-transform infrared, investigated the structure of LPs at various concentrations of trehalose. The results indicate that the LP structures and conformation were considerably modified (p < 0.05) following trehalose conjugation. The surface charge and hydrophobicity of the trehalose-conjugated LPs (T-LPs) were significantly altered (p < 0.05), from -22.7 to -31.4 and 753 and 543 a.u., respectively. Furthermore, the digestibility and solubility of T-LPs increased from 75% to 81.8% and 60% to 66%, respectively. In conclusion, this study showed that combining LPs and trehalose conjugation could improve the quality of conjugates LPs, which could expand their use in manufacturing as the acceptance of plant-based diets increases. PRACTICAL APPLICATION: Currently, lentil proteins (LPs) are used in plant-based protein powders and supplements. Though less popular than soy or pea proteins, LPs are valued for their high protein content and good amino acid profile. LPs are utilized in meat alternatives and high-protein snack products. The application of these products is mainly due to their nutritional benefits rather than functional properties due to their poor water solubility. Increasing the water solubility of LPs could significantly expand their application in various food industries, making LPs a more competitive and functional plant-based protein source. Trehalose-conjugated LPs with better water solubility allow LPs to be used in other food products, such as plant-based protein beverages. Better solubility would enhance the clarity and smoothness of these products, making them more appealing to consumers.</p>","PeriodicalId":193,"journal":{"name":"Journal of Food Science","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142491674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key therapeutic goal to reduce PHG is the inhibition of α-amylase (αAM) and α-glucosidase (αGL), enzymes that break down carbohydrates into sugars. Cucurbita moschata has been shown to inhibit both enzymes. However, its inhibition mechanism has not been explored. This study investigated the in vitro inhibition mechanisms of αAM and αGL and conducted a metabolomic analysis of C. moschata (edible part) water-extract (CME), aiming to preliminarily identify its bioactive compounds (BCs). The inhibitory mechanisms were determined using Lineweaver-Burk plots. The BCs were identified and quantified using HPLC-QTOF-MS, employing both targeted and untargeted metabolomic approaches. CME had a significant higher effect (p < 0.05) on αAM activity than against αGL with IC₅₀ of 28.99 and 698.42 mg/mL, respectively. The extract showed mixed and uncompetitive type inhibitions on αAM and αGL, respectively. The lowest inhibition constant (K_i) was 47.68 mg/mL on αAM activity at 20 mg/mL. Untargeted metabolic profiling by UPLC-MS-ESI-QTOF putatively identified 30 compounds in CME, such as amino acids, vitamins, phytohormones, fatty acids, cucurbitacins and phenolic acids, and flavonoids. Functional analysis of CME identified significant pathways, including pantothenate and CoA biosynthesis and phenylpropanoids, among others. The targeted analysis by UPLC-MS-ESI-QqQ allowed us to identify 12 compounds, with l-phenylalanine, p-hydroxybenzoic, and p-coumaric acid as majors. This study demonstrated the inhibitory potential of CME on αAM and αGL activities, which may be attributed to its metabolites. Thus, this plant represents a valuable source of BC against PHG. Practical Application: The research highlights that Cucurbita moschata has significant potential in managing postprandial hyperglycemia in diabetic patients by inhibiting enzymes like α-amylase and α-glucosidase. In addition, the identification of its compounds emphasizes its importance as a source of bioactive compounds. Therefore, C. moschata could be effectively utilized in the development of nutraceuticals or as an ingredient in functional foods specifically designed for postprandial hyperglycemia management. Thus, integrating C. moschata as part of the daily diet could offer patients with diabetes a natural alternative to control their blood glucose levels after eating.</p>","PeriodicalId":193,"journal":{"name":"Journal of Food Science","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142491675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the effects of NaCl replacement with SHH, KCl, and Ca-ascorbate on the quality of low-sodium Cantonese sausage were investigated. Four groups of salt formulation, I (100% NaCl), II (NaCl/KCl/Ca-ascorbate = 60%/30%/10%), III (NaCl/KCl/Ca-ascorbate/SHH = 50%/30%/10%/10%), and IV (NaCl/KCl/Ca-ascorbate/SHH = 30%/30%/10%/30%), were used to produce Cantonese sausages. The moisture and nitrite content decreased, the microbiological growth was inhibited, and the protein content increased after adding SHH for Cantonese sausages with NaCl substitution degrees of 50% and 70%. The saltiness, overall flavor, color, and texture of low-sodium Cantonese sausages with SHH were maintained or improved compared to the Cantonese sausage without sodium replacement. The proportion of peptides with molecular weight <1 kDa in Cantonese sausages increased after adding SHH, which may improve the overall flavor by interacting with peptides or other compounds. SHH combined with KCl and Ca-ascorbate is an efficient NaCl substitute, which can maintain and even improve Cantonese sausage quality and reduce sodium content up to 70%.

Based on the determination of the metabolites of PPA-NPs, in vivo experiments were conducted in rats to investigate the absorption and metabolism, antioxidant activity, and the impact on the intestinal microbiota of PPA-NPs. UPLC-Q-TOF-MSMS analysis showed that the absorption of anthocyanins was increased by 220.36% in rats gavaged with PPA-NPs compared to rats gavaged with PPA directly. Subsequent in vivo experiments revealed that PPA-NPs significantly bolster primary antioxidant markers, evidenced by elevated glutathione and superoxide dismutase levels and reduced malondialdehyde content. Moreover, PPA-NPs were found to positively alter the gut microbiome structure in aged rats, notably increasing the abundance of beneficial bacteria, such as Lactobacillus and Rothia, and improving microbial diversity. These findings suggest that W/O/W PPA-NPs markedly improve the bioavailability of PPAs, showcasing promising antioxidant properties and potential health benefits for gut health in vivo.

Moreover, low consumption of omega-3 fatty acids in modern diets serves as a major cause for increased prevalence of cardiovascular diseases. The stability of such oils can be improved by techniques like blending and interesterification. However, blending lacks uniformity, which can be overcome by interesterification. The process conditions, namely, enzyme load, temperature, substrate molar ratio, and reaction time, were systematically optimized using response surface methodology.
