Processamento de biscoito a partir de ingredientes funcionais: fibra de albedo de maracujá e xilitol

Abstract

Biscuit is one of the most commercialized in Brazil, its ingredients are high in hydrogenated fat, low fiber content and high calorie. These ingredients contribute to increased cholesterol, triglycerides and obesity. Consumers are children and teenagers, who enjoy the sweet taste, sensory aspect and practicality. Incorporation of functional ingredients in food products has grown in recent decades. The albedo of yellow passion fruit (Passiflora edulis f. flavicarpa) is an agroindustrial residue utilized as dietary fiber. Xylitol is a sweetener whose metabolism occurs via the pentose phosphate independent of insulin, low calorie and inhibits the incidence of caries. The objective was to develop functional biscuit with nutritional properties, fiber-enriched albedo of passion fruit, sweetened with xylitol and evaluation of the physical, physicochemical and sensory. The cookies were prepared by adding fiber to the concentration of 3, 6, 9 and 12%, 10% of xylitol and control with the traditional formulation. The data were analyzed for texture, water activity, soluble solids, pH, pectin, nutritional value and sensory analysis. The results confirm the changes in levels of lipids, carbohydrates, protein, fiber and calories compared to control cookies. The cookie was preferred with 3% fiber, and also the most accepted among the tasters, 71.43% said they liked a lot. In proportion with 12% fiber negatively influenced the texture and acceptability. We conclude that the biscuit enriched with fiber at a rate of 3% is more suitable for development of alternative foods.
