Edible mushrooms are alternatives for the recycling of these residues and the substrate generated at the end of the bioprocess can be used in the elaboration of food products, since its nutritional characteristics, combined with the richness of available nutrients, favors the utilization of these by-products. In addition, the environmental impacts caused by irregular waste disposal are minimized. The objective of this research was to develop and characterize three shakes, formulated with bioproducts resulting from the processing of pineapple peel as an alternative food, source of fiber. The bioproducts were characterized for antioxidant activity, total phenol content, in vitro protein digestibility, bioassay of toxicity against Artemia salina, qualitative hemolytic activity and cytotoxic activity against human MCR5 fibroblasts. Shakes were made using formulations composed of powdered bioproducts in the proportions of 0 and 100%, replacing oat flour to obtain four formulations, including the standard one. The shakes produced were submitted to determination of centesimal composition, mineral content, determination of pH and total titratable acidity, and determination of the microbiological quality. The bioproducts presented antioxidant activity and reduced content of total phenols and high protein digestibility. All toxicological tests have shown that these products are safe for human consumption. When oatmeal was replaced by bioproducts there was an increase in minerals and fibers contente and the reduction of total calories. In addition, there was increase of potassium, calcium, sodium, copper and manganese. The pH of the shake products presented lower value than the standard sample, higher total titratable acidity and microbiological quality within the sanitary and hygienic specifications. A ind??stria de alimentos produz uma s??rie de res??duos de alto valor econ??mico que, se submetidos ?? tecnologias adequadas, podem ser convertidos em produtos comerciais ou mat??rias-primas para processos secund??rios. Para a reciclagem destes res??duos, os cogumelos comest??veis s??o alternativas para produ????o de biomassa, sendo que o substrato gerado ao final do bioprocesso pode ser utilizado na elabora????o de produtos aliment??cios, pois suas caracter??sticas nutricionais aliadas ?? riqueza de nutrientes dispon??veis favorece o aproveitamento desses subprodutos. Al??m disso, os impactos ambientais causados pelo descarte irregular de res??duos s??o minimizados. Esta pesquisa teve como objetivo desenvolver e caracterizar tr??s produtos aliment??cios do tipo shake formulados com bioprodutos resultantes do processamento da casca de abacaxi como uma alternativa alimentar fonte de fibras. Os bioprodutos foram caracterizados quanto ?? atividade antioxidante, teor de fen??is totais, digestibilidade in vitro das prote??nas, bioensaio de toxicidade frente ?? Artemia salina, atividade hemol??tica qualitativa e atividade citot??xica contra fibroblastos humanos MCR5. Os shakes foram elaborados utilizando formula????es compostas pelos bioprodutos em p??, nas propor????es de 0 e 100%, em substitui????o ?? farinha de aveia para obten????o de quatro formula????es, incluindo a padr??o. Os shakes produzidos foram submetidos ?? determina????o de composi????o centesimal, teor de minerais, determina????o de pH e acidez titul??vel total, e determina????o da qualidade microbiol??gica. Os bioprodutos apresentaram atividade antioxidante e reduzido teor de fen??is totais e elevada digestibilidade de prote??nas. Todos os ensaios toxicol??gicos revelaram que se tratam de produtos seguros para o consumo humano. Quando substitu??da a farinha de aveia pelos bioprodutos houve aumento de minerais, fibras, pot??ssio, c??lcio, s??dio, cobre e mangan??s, al??m da redu????o das calorias totais.. O pH dos produtos do tipo shake apresentaram menor valor que a amostra padr??o, maior acidez titul??vel total e qualidade microbiol??gica dentro das especifica????es higi??nico-sanit??rias em vigor.
