Desenvolvimento tecnológico e avaliação de suplemento proteico multifuncional contendo extrato de Ascophyllum nodosum (L.) LE JOLIS

Abstract

This work was to develop and to evaluate the quality of a novel formulation of powder protein containing whey proteins, vitamins, minerals, antioxidants, soluble fiber and extract of Ascophyllum nodosum (L.) Le Jolis which is intended for supplying protein intake at the same time aiding weight loss. Physicochemical analyzes, microbiological tests and sensorial evaluation were performed. The formulatiaon resulted in a solid-looking product. The energetic value was about 140.0 kcal in 40 g portion with protein contents close to 70%. Carbohydrate level of 16.4% and lipids of 1.2% were observed. In general, the product presented all the requirements to fit it as a compensating food. Values in colony-forming unit lower than that recommended by the legislation for coliforms at 45° C, coagulase positive staphylococci and Bacillus cereus, and absence of Salmonella sp. were verified. This supplement had an adequate acceptability index – greater than 70% – when evaluated by the affective testing. Take all these into account, the multifunctional protein supplement containing A. nodosum extract was successfully developed and provided the required/proposed quality requirements.
