Caracterização físico-química, nutricional e aceitabilidade de um pão enriquecido com farinha múltipla composta por ingredientes amazônicos.

Abstract

Brazil has made great strides in the field of food and nutrition security by adopting public policies to improve the social conditions and power of the most vulnerable social groups. However, rates of underweight and stunting in children under five, in the northern region are 3.3% and 14.7%, respectively. According to OMS, for both indices should be below 2.3%. In past decades, food science, was concerned with developing food for human survival, a goal that was replaced by the concept of producing it with quality and as vehicles for promoting wellness, while reducing the risk of diseases. Multiple flour is an alternative food supplement intended to combat child malnutrition. However, there are questions about its quality especially on hydrogen cyanide present in cassava leaves. Bread is a staple food consumed worldwide, and its composition is mainly of wheat flour, water, salt and yeast.The aim of this research was to develop an enriched bread with a flour composed of multiple regional ingredients - pupunha flour, amaranth powder and pumpkin seed caboclo powder. The microbiological, physicochemical and sensory properties of the final product were evaluated. Sensory acceptability test was applied, using a nine-point hedonic scale, with one hundred tasters who evaluated the sample bout color, flavor, texture and overall acceptability. The moisture content found in enriched bread was 35.5%, ash 1.6%, 3.0 fiber, 5.4% protein, 2.3% lipid and carbohydrate 52.2%. The microbiological characteristics were in accordance with the standards set out in legislation. There was a slight decrease in pH of enriched bread after three days and slight increase after seven days. The enriched bread formulation had good acceptability and purchase intent, obtaining scores between the terms "liked" and "liked it very much". The use of multiple flour made of Amazonian ingredients changed the chemical composition of the bread, especially increased levels of dietary fiber; having a concentration of 3% fiber, this value characterize the product is a fiber source.
