Patties were designed to vary in water holding and release properties by controlling hydration level (water:TVP ratio 1:1, 1:3, 1:5) and particle size (particle surface area 0.2, 10, 20 mm<sup>2</sup>) of Textured Vegetable Protein (TVP). Increasing TVP hydration level increased water cooking loss, while fat cooking loss remained unchanged. Despite this, higher initial water content still led to a 30 % increase in water content and a 51 % decrease in stiffness of cooked patties. The elevated water content significantly enhanced serum release under compression, which strongly influenced juiciness and fattiness perception. Increasing TVP hydration level increased juiciness (+204 %) and fattiness (+71 %), but decreased hardness (−53 %) and crumbliness (−41 %) intensity. Increasing TVP particle size increased cutting work during blade cutting tests, yielding harder (+62 %) and chewier (+119 %) patties. Network analysis revealed that increased juiciness enhanced fattiness, savory and garlic flavor and decreased hardness intensity. These variations in sensory properties influenced liking, which was positively related to juiciness, chewiness and savory flavor, and negatively to beany flavor. We conclude that increasing TVP hydration level effectively alters patty composition and texture and enhances juiciness of PBMA patties, while varying TVP particle size primarily impacts patty texture without affecting composition. Juiciness of PBMA patties is driven by retained water after cooking, serum release under compression and stiffness. Enhanced juiciness not only boosts flavor perception but also drives consumer liking.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"167 ","pages":"Article 111423"},"PeriodicalIF":11.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855110","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}

Food foam-type products, such as meringue, whippable drinks, and ice cream, rely heavily on protein functionality. Understanding the mechanisms by which oat proteins form and stabilize foam is crucial for their application in such products. This study relates the foaming properties of non-kilned oat protein fractions enriched in either water-soluble proteins or unaggregated 12S globulins to their behavior at air-water interfaces (using maximum bubble pressure and (oscillating) rising bubble tensiometry) and during the drainage of thin liquid films (using a pressure-controlled microfluidic set-up). Both water-soluble oat proteins and 12S globulins were capable of producing a high volume of stable foam. The foaming capacity of the water-soluble oat proteins was attributed to their high diffusion rate to the air-water interface, while their foam stability was ascribed to the rapid formation of a viscoelastic interfacial film. The foaming capacity of oat 12S globulins was driven by extensive protein structural reorganization upon adsorption, likely involving dissociation and reassociation of oligomers and protein subunits, after surpassing an energy barrier-controlled adsorption regime at very low surface ages. The stability of oat 12S globulin foams was attributed to enhanced thin liquid film stability, resulting from reduced Laplace pressure gradients, and increased disjoining pressure due to combined electrostatic and steric repulsion. This study provides novel mechanistic insights into the foaming properties of oat proteins, paving the way for their utilization in plant-based foods.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"167 ","pages":"Article 111426"},"PeriodicalIF":11.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848594","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}

This study systematically investigated the regulatory effects of CP at different aging stages on the binding behavior of EGCG with α-amylase (PPA) and its <em>in vitro</em> hypoglycemic activity. The results of the study demonstrated that CP significantly interfered with the inhibitory effect of EGCG on PPA in a time-dependent manner.
