Development of technology for producing wheat bread enriched with soy ingredient

Nutritional supplements produced from soy and being rich in protein, fat and many other valuable substances have become a promising source of fortification of bakery products. This study aimed to develop a technology for producing wheat bread enriched with a protein-vitamin-mineral ingredient (PVMI) obtained from germinated soybeans. When kneading the dough, PVMI was added together with wheat flour and other dry components. Mathematical modeling of the wheat bread sensory evaluation showed the optimal content of PVMI in the recipe was 20% of the weight of wheat flour. As a result of the correlation-regression analysis, the most rational production characteristics for obtaining bread enriched with BVMI have been established. The amount of protein in the bread sample increased by 71.9%, dietary fiber - by 40.9%, vitamin E - by 34.7%, vitamin B1 - by 190%, vitamin B2 - by 80%, choline - by 186%. The fat quantity was 4.1 times more. At the same time, the total carbohydrate content decreased by 18.1% compared to the control sample. The improved chemical composition makes it possible to classify wheat bread with PVMI as an enriched food product.

Automated summary

This study developed a technology to enrich wheat bread with a protein-vitamin-mineral ingredient (PVMI) obtained from germinated soybeans. The optimal content of PVMI in the recipe was determined through sensory evaluation. The bread enriched with PVMI showed significantly increased protein, dietary fiber, and vitamins, while the total carbohydrate content decreased.
