Irradiação em barras de cereais incorporadas com casca de abacaxi

Abstract

One of the major current concerns to the food industry is the management of residues generated in its production processes. Thus, several studies have been developed, seeking alternative uses for these residues, in order to minimize environmental impacts and add value to products previously discarded. Combining this idea with the increasingly search for healthy and practical products, by consumers, this study aimed the characterization of cereal bars irradiated with doses of 0 kGy, 1 kGy, and 2 kGy, incorporated with dried pineapple skin. The following analyses were carried out: moisture, proteins, lipids, ashes, carbohydrates, energetic value, antioxidant potential, phenolic content, organic acids, and fatty acids profile. The results observed for the centesimal composition did not vary as a function of the radiation doses used, reducing only the levels of antioxidants, phenolic compounds, and organic acids. The product showed potential for becoming an effective way of reusing a food industry residue and the irradiation interfered on the nutritional characteristics of the final product.
