title: [Evaluation of soy bean proteins obtained by pressure].
abstract: Besides the processes of extrusion and protein fiber spinning, analogous utilization research with a range of protein sources is continuing at an accelerated pace. However, the pressure forming process, an attractive process for producing protein foods, has not received the attention as it merits. The fabrication techniques contribute the advantages of nutritional value, economic and simplicity in manufacture; it can be extend to utilize in the development of useful textured vegetable protein foods. Here, we present a pressure forming process for producing protein foods with soybean grains. In this paper, we evaluated the composition, and the yield of the products obtained by this process; the trypsin inhibitor and enzymatic proteolyse of the products were also studied. The product obtained contents soluble and insoluble proteins of soybean, 45 p. 100 of protein (N x 6,25), 20-25 p. 100 of carbohydrates of which the fibers are included; moreover it contents 6-7 p. 100 of ash and 20-22 p. 100 of fat. It does not content any starch, the oligosaccharides and antinutritional factors were almost eliminated. This product presents in acceptable textural form resembling traditional animal protein foodstuffs; its fonctional and nutritional properties can meet different utilizations in foodstuffs such as dietetic products and protein complements.
