Ultrasound treatment did not affect the solubility of both proteins significantly but the emulsion and foam properties were increased up to 10 min. Nevertheless, microwave treatment after ultrasound caused a significant decrease in the solubility of both proteins. However, the foam stability of the WPC and WGP was not significantly modified after microwave treatment. The obtained results showed a more positive effect of ultrasound at 100 W for 10 min than other ultrasound treatments on the functional and structural properties of both proteins. The zeta potential of both proteins was decreased after dual physical modifications, but thermal stability of proteins was improved after microwave treatment.","PeriodicalId":12331,"journal":{"name":"Food Science and Technology International","volume":" ","pages":"397-406"},"PeriodicalIF":2.3,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9674124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the tomato industry, where only completely red tomatoes are used, unripe and non-red tomatoes constitute an important by-product, with important losses in the field of a perfectly edible vegetable food source. To give value to this unripe tomato, a fermentation with a consortium of lactic acid bacteria and yeast was previously optimized, originating an acidic pulp with optimized nutritional characteristics and great potential for salad dressing development. Pulp's texture was improved with two hydrocolloid systems: 0.5 g/100 g of xanthan gum; and a mixed system of xanthan gum and kappa-carrageenan (0.1 g/100 g each). After rheology optimization, spices and condiments were added to the thickened fermented pulp, and promising tasty sauces were obtained. These sauces were presented to a consumers' panel, with good acceptance. The production of these new healthy sauces aims to mitigate unripe tomato waste, adding value to the tomato industry by using a major industrial by-product.","PeriodicalId":12331,"journal":{"name":"Food Science and Technology International","volume":" ","pages":"418-427"},"PeriodicalIF":2.3,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10337275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the physicochemical properties of mango flours and starches obtained from different parts of the fruit of two cultivars were evaluated. Mango peel flours have higher levels of proteins, fibers, minerals, carotenoids, ascorbic acid, and antioxidant activity than pulp flours, in addition to a higher yellowing index and water and oil-holding capacity, and can be used as a functional flour. The pulp flours, with the higher starch content, showed characteristics that make them valuable as a potential ingredient in soft baking and gluten-free products. Mango starches have circular and oval shapes, with a bimodal distribution. All starches showed an A-type crystallinity pattern. Pulp starches showed a higher peak viscosity and breakdown, with a lower setback, and can be used as a thickening or gelling agent. The higher thermal stability of kernel starch suggests its application in sauces, baking, dairy products, and canned foods.","PeriodicalId":12331,"journal":{"name":"Food Science and Technology International","volume":" ","pages":"10820132241259055"},"PeriodicalIF":2.3,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141295894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 investigated the influence of wheat brewer's spent grain (WBSG) on the physicochemical properties of dough and steamed bread-making performance. The incorporation of WBSG in wheat flour significantly increased water absorption, development time, and degree of softening while decreasing the stability time of blending dough. Excessive WBSG up to 20% restricted the dough formation. WBSG contributed to the remarkable increase of pasting viscosities, pasting temperature, and immobilized water proportion in doughs. For all doughs, storage moduli (G') were higher than viscous moduli (G″). WBSG addition resulted in higher moduli values and the formation of highly networked gluten structure, finally leading to the lower specific volume, spread ratio, and elasticity of bread. Lightness (L*) of bread decreased with increasing WBSG while redness (a*) and total color difference (ΔE) augmented. Low WBSG addition (≤5%) could endow steamed bread with the appearance of a chocolate-like color and pleasant malt flavor, which is acceptable for most consumers. Nevertheless, the improvement of nutritional and functional characteristics of steamed bread incorporated with WBSG should be more focused in the future.","PeriodicalId":12331,"journal":{"name":"Food Science and Technology International","volume":" ","pages":"10820132241260453"},"PeriodicalIF":2.3,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141283410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four formulations were prepared: control, 0.02% of sodium nitrite in brine curing, w/v (CON); 1.5% BG in brine curing, w/v (ASU); 1.5% BG in dry curing, w/w (ASS); and 1.5% of BG in the brine curing, w/v and 1.5% of BG in dry curing, w/w (ASUS). Nutritional composition, pH, water activity, shear force, fatty acid profile, color, and oxidative stability of the formulations were analyzed. The addition of BG did not affect the nutritional composition, pH, water activity, shear force, and fatty acid profile. On the other hand, it resulted in lower weight loss after centrifugation and lower values of L* and a*. TBARS values from the 30th day of storage were lower in the ASUS formulation, while carbonyl compounds at all times were lower than in the CON formulation. Results suggest that BG was an efficient alternative to nitrite in controlling protein oxidation during storage. Thus, the use of pork for the manufacture of jerked beef can be an alternative, and black garlic can be applied as a natural additive to the replacement of nitrite.
