Avaliação da influência das avarias da soja moída na solubilidade proteica do farelo de soja

Abstract

The weather conditions for the 2022 soybean crop caused damages in terms of productivity and grain quality. The production had been growing over the years and in this climatic scenario it had a significant drop, however without affecting the soybean meal market that continued to grow. For potassium hydroxide soluble protein, there was a decrease in the rates compared to previous years. This is the protein that is absorbed by the animal body after ingestion. The soluble protein may change due to the quality of the raw material and exposure to high temperatures during processing. Therefore, the present work evaluates, through graphic figures, the relationship between the content of damaged grains and soluble protein, applying data dispersion analysis through the statistical parameters standard deviation, variance and test of hypotheses, t test. With this, it was concluded that the data referring to the two analyzed periods have a significant difference between them, with large oscillations in the result during the analyzed time. The behavior of the soluble protein presented variation according to the content of damaged grains in ground soybeans, being more visible for levels greater than 6% damaged.
