Verificação da representatividade de amostragem da lecitina de soja por meio de análises físico-químicas

Abstract

The industry of soybean crushing which uses physical degumming process has the soybean gum which is used to produce soy lecithin. The obtaining process of soy lecithin is carried out by batch, and the union of approximately 10 batches will form the final lot. During the batch process, the food industries end up performing the monitoring of quality parameters, being they specifically raw color, moisture and viscosity, which are important parameters in the representativeness of the quality on the final lot. When the batch process is completed, the lecithin obtained goes to the final viscosity tank, where it will circulate under continuous heating and stirring, being this necessary for the homogenization between the batches. The final viscosity tank is completed on its volumetric capacity and a new sample is collected and is physico-chemically analyzed. The same analyses of each batch are also made and others analyses are necessary for the lot release, targeting the final product to specific tanks depending on the results obtained. The following graduation work is aimed at monitoring the sampling of each batch and the sampling of the final tank in order to verify if the parameters obtained during the batch match the same parameters found in the final tank through physicochemical analysis.
