There is evidence that the cooking time of yellow beans is linked to the dietary fiber content and may also contribute to nutrient digestibility and bioavailability. Therefore, 52 fast-, moderate-, and slow-cooking yellow beans with diverse iron bioavailability from five market classes (Amarillo, Canario, Green-yellow, Manteca, and Mayocoba) were selected for total dietary fiber (TDF) analysis. TDF was measured as insoluble (IDF) + soluble (SDF) + oligosaccharides (OLIGO) using method AOAC2011.25. Wide variations in the concentrations of IDF (16.0–23.1%), SDF (1.6–7.7%), OLIGO (1.5–3.4%), and TDF (20.6–31.3%) were detected among the yellow beans with various cooking times. Lower concentrations of IDF in yellow beans were associated with shorter cooking times and higher iron bioavailability. The larger sized Andean yellow beans had more SDF than Middle American. One Mayocoba breeding line from Puerto Rico, PR1146-124, had 42% less OLIGOs than average, and may be useful for breeding low-flatulence beans for consumer acceptability. Fast cooking yellow beans provide the same SDF and OLIGO concentrations as yellow beans with longer cooking times but have the added benefit of shorter cooking times (convenience) and provide more bioavailable iron after cooking.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"10 ","pages":"Article 100942"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11681885/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142902675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oil was incorporated in the form of an emulsion, and for comparison also directly added without prior emulsification. For oil addition by emulsion, several plant-based protein sources were compared as emulsifier. The choice of protein emulsifier had a strong effect on wedge length of the extrudate, the maximum linear strain and value of G′ in shear, and the rupture strength of the extrudate. Two screw configurations were used. One with 1 kneading disc section and another with 4 kneading disc sections. It was found that fewer kneading discs in the screw led to less mechanical energy input, leading to less shear on the dough in the extruder. The use of fewer kneading elements resulted in less oil leakage from the product, while the product also was stronger, as demonstrated by the higher rupture strength in the texture analysis, and higher storage modulus G’ in oscillatory shear rheology. Less deformation of the air pockets between protein structures could be seen in the screw with fewer kneading discs in multiphoton microscopy. As a result, both the screw configuration and the interfacial properties of the plant protein emulsifier need to be considered when developing meat alternative products containing oil as a route to control the texture of these products.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"10 ","pages":"Article 100989"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liver metabolomics analysis indicated that LGG@Se intervention altered liver metabolic profiling, and the characteristic biomarkers were mainly involved in amino acid metabolism, including alanine, aspartate and glutamate metabolism, arginine biosynthesis, <em>etc</em>. In addition, LGG@Se intervention modulated the expression of genes and proteins related to lipid metabolism and oxidative stress in liver of over-drinking mice. Western blot analysis revealed that LGG@Se intervention up-regulated the expression of intestinal barrier function-related proteins, thereby ameliorating alcohol-induced intestinal barrier damage.

The detection of (in)consistency requires evaluations on two connected scales. The suggested approach is illustrated by data from sensory tests of biscuits enriched with three pollens at different levels. 100 consumers evaluated the samples on two different scales (nine category monotonic ascending hedonic response scale, five-category just about right (JAR) intensity scale). The 88 consistent assessors are found using a wider range of both the liking scale and JAR scale than the 12 inconsistent assessors whose evaluations do not have a significantly negative rank correlation. Future consumer tests are recommended to include multiple scales. The proposed framework aims to identify and even filter out the potentially biasing inconsistent evaluations.
