Produção e avaliação microbiológica, fíco-química e toxicológica de farinha de pilosocereus chrysostele e sua utilização como aditivo na formulação de broa preta.

Abstract

The cacti are an important element of the landscape, with succulent stems, covered with spines of many shapes, sizes and dimensions, where it grows in rocky soils and, along with other cactus species, form the typical landscape of the semi-arid region of Brazil. The facheiro (Pilosocereus chrysostele) is a xerophytic cactus, rugged, sparsely branched, dark green color, armed with sharp thorns; with large isolated and tall flowers. he purpose of this study was to develop a study to obtain flour from the stems and bark facheiro in four different temperatures and determine the microbiological characteristics, physicochemical and toxicological in order to investigate the potential use in the food industry and check for the possibility of developing new products of baking, acceptable by consumers. Four formulations (5, 10, 15 and 20%), by varying the amount added to the basic formulation of the cookie, in order to support product development in the field of baking, the bread black production process. We used the acceptance test with hedonic scale of nine points, including questions about consumption and purchase. The results of the microbiological analyzes in the four flours met the standards required by law, with negative results for coliform 45 ° C, Staphylococcus aureus, Bacillus cereus, aerobic mesophilic bacteria, molds, yeasts and Salmonella sp. In physical-chemical results obtained from the pulp and peel facheiro showed lower values of moisture and high ash content, fiber and lipids and reasonable amounts of protein. No toxic effects were observed, indicating the safety of this product for supplementation in food. Facheiro flour as a replacement to traditional flour produced black bagel sensorial quality in the overall acceptability and purchase intent of tasters. Proving the efficiency in the production of flour, and sanitary hygienic quality of the same and can be used in many food formulations without compromising the quality of their products to consumers' health.
