Resumo Os métodos sensoriais descritivos permitem a detecção, descrição e quantificação dos atributos presentes em um alimento. Estes são utilizados pela indústria de alimentos no desenvolvimento novos produtos, controle qualidade, nas alterações ingredientes e/ou formulações na avaliação produtos durante estocagem. Porém, maioria das técnicas descritivas existentes necessita da utilização avaliadores treinados emprega uma escala não estruturada para avaliar os produtos. Isto torna as...

Five different concentrations of golden flaxseed flour (0%: F0 (control), 5%: F1, 10%: F2, 15%: F3, 20%: F4) were used as a functional ingredient to replace the fat in chicken burgers. The products analyzed for moisture, protein, carbohydrate, fat, ash, shear force, consumer acceptance, and their sensory technological characteristics. protein contents raw hamburgers did not differ significantly. An increase concentration caused decrease moisture content an ash content. addition positively...

Front-of-package (FOP) nutrition labelling schemes were developed to improve consumer's comprehension about the food nutrients associated with non-communicable diseases (NCDs). Several FOPs have already been developed, and Brazil is in process of evaluating a scheme introduce products. The aim this study was investigate impact TLS, proposed by industry, on product healthfulness perception. A 141 participants carried out. conjoint task designed considering three categories levels: types dairy...

ABSTRACT: Brazil nut is a typical oilseed from the Amazon region, of great economic and cultural importance. Due to its high nutritional value, it interesting be used as matrix for new products’ development. Thus, present study aimed develop characterize drink based on nuts fermented by Lactobacillus casei added with inulin. After formulated, was pasteurized, fermented, maturated, stored under refrigeration 28 days. Physical, chemical, microbiological, sensory analyzes were performed before...

A large body of evidence assessing the effectiveness front-of-package (FOP) nutrition labeling exists. Most experimental studies have been conducted with fictitious products. However, consumers’ perception depends on several products extrinsic factors such as brand. Understanding how strong brand associations influence FOP schemes may be crucial to informing policymaking. In this context, aim work was evaluate effect five different variants nutritional warnings labels (black magnifier, red...
