Efeito da desodorização nas características sensoriais de extratos hidrossolúveis de soja obtidos por diferentes processos tecnológicos

Abstract

The products obtained from the soybean have shown multiple technological and nutritious advantages but, in spite of that, they haven't been easily accepted by Brazilian consumers mainly because of their unpleasant sensory characteristics of odor and flavor. Deodorization can be a good and effective method in the attempt to remove the volatile compounds that produce these characteristics. Hydro soluble soybean extracts, commonly known as soybean milk, have been obtained from three different processes and, later on, submitted to deodorization process from steaming, at atmospheric pressure. The products, both in the natural and deodorized states, have been evaluated by Quantitative Descriptive Analysis. The results have shown that the deodorization process has been effective, reducing both the raw soybean odor and the aftertaste as well, improving the typical flavor in the processes of getting the milk from "mechanical cow" or maceration. © 2006 SBCTA.
