Consumers are more aware and demanding of healthy food options, besides being concerned with environment-friendly consumption. This paper aims to evaluate nutritional, technological, and sensory characteristics of legumes and their products’ quality and versatility, considering potential applications in new food options. Legumes are foods that have a recognized nutritional group since they have high protein and fiber content. However, their consumption is still somehow limited for some reasons: in some countries it is not easy to find all the species or cultivars, they need an organization and planning before preparation since they need soaking, and there is the presence of antinutritional factors. Due to the different functionalities of legume proteins, they can be applied to a variety of foods and for different purposes, as grains themselves, aquafaba, extracts, flours, brans, and textured proteins and sprouts. These products have been inserted as ingredients in infant food formulations, gluten-free foods, vegetarian diets, and in hybrid products to reduce food costs as well. Foods such as bread, cakes, cookies, meat analogues, and other baked or cooked products have been elaborated with nutritional, technological and sensory quality. Further development of formulations focused on improving the quality of legume-based products is necessary because of their potential and protein quality.

Grapes are one of the most cultivated fruits in the world. Concomitantly, a large amount of waste is generated from this product. Grape pomace (GP) flour can be used as an increment for making new food products. GP is rich in fibers and phenolic compounds, and in addition could be used to reduce agro-industrial residues. Thus, the objective of this study was to evaluate the influence of the addition of different percentages of grape pomace (GP) on the chemical, technological, and sensory characteristics in pasta and bakery products. An integrative review was conducted. The selection of papers was carried out by searching studies in databases. An improvement in chemical quality with the addition of GP was observed, such as fiber, anthocyanin, and micronutrient content. Biscuits, cookies, cakes, breads, and pasta did not show any impairment in terms of acceptability. However, biscuits and cookies had the best global acceptance. The degree of acceptance still seems to be low for the use of GP to be included in high quantities in successful products. Samples with a maximum of 10% addition of GP flour seem to be accepted. On the other hand, the higher the percentage of GP flour, the healthier benefits they seem to promote.

O objetivo desse estudo foi analisar as propriedades reológicas e a aceitabilidade de espessantes domésticos em diferentes líquidos, além de comparar os custos e o valor energético desses espessantes. Avaliaram-se no viscosímetro de Brookfield amostras à base de farinha de fécula de batata, de amido de milho, de polvilho doce e de farinha de arroz, além de dois espessantes comerciais, diluídos em líquidos. Foi realizada, com a participação de 30 avaliadores, a investigação de aceitabilidade dos espessantes em água, leite e suco para os atributos: aparência, consistência, odor, sabor e aceitação global. A viscosidade em água dos espessantes comerciais, do amido de milho e da farinha de arroz não teve diferença estatística significativa entre si. Um dos espessantes comerciais atingiu a consistência “rala”. Os resultados de leites e sucos foram semelhantes quando classificados por consistência. Na aceitabilidade dos atributos odor e sabor para água, o espessante comercial, a fécula de batata, o polvilho doce e a farinha de arroz não apresentaram diferença significativa entre si. No leite, para os atributos odor e sabor as amostras não tiveram diferença significativa entre si e para sucos, o espessante comercial, a fécula de batata e o polvilho doce não apresentaram diferença significativa. A viscosidade de um dos espessantes comerciais não estava adequada para o consumo por pacientes com disfagia, obtendo consistência “rala”. O espessante comercial E.C1F e o amido de milho (AM) apresentaram consistência “mel”, sendo apropriado para o consumo em líquidos. As amostras com leites foram as que apresentaram maiores viscosidades, a maioria obteve consistência “pudim”. A aceitabilidade da E.C1F e da fécula de batata (FB) em leite foram as que mais se destacaram promissoras.
