Abstract Soy protein isolate is a worthy substitute for meat protein. However, its low level of digestibility limits its spread to new market niches. This problem can be solved by enzymatic hydrolysis of soy protein to peptides. Several research teams have already been solving this problem, but their results were obtained under laboratory conditions and do not provide information about the reproducibility of the results on an industrial scale. In this paper, we have compared the results of laboratory and semi-industrial experiments of enzymatic hydrolysis of protein. Also the kinetics of the reaction under different conditions is shown, and the final product is characterized. The obtained results of semi-industrial experiments can form the basis of industrial regulations for the production of soy protein hydrolysate as an easily digestible form of dietary protein for athletes and patients with digestive disorders.

Composite materials based on proteins and carbohydrates normally offer improved water solubility, biodegradability, and biocompatibility, which make them attractive for a wide range of applications. Soy protein isolate (SPI) has shown superabsorbent properties that are useful in fields such as agriculture. Alginate salts (ALG) are linear anionic polysaccharides obtained at a low cost from brown algae, displaying a good enough biocompatibility to be considered for medical applications. As alginates are quite hydrophilic, the exchange of ions from guluronic acid present in its molecular structure with divalent cations, particularly Ca2+, may induce its gelation, which would inhibit its solubilization in water. Both biopolymers SPI and ALG were used to produce composites through injection moulding using glycerol (Gly) as a plasticizer. Different biopolymer/plasticizer ratios were employed, and the SPI/ALG ratio within the biopolymer fraction was also varied. Furthermore, composites were immersed in different CaCl2 solutions to inhibit the amount of soluble matter loss and to enhance the mechanical properties of the resulting porous matrices. The main goal of the present work was the development and characterization of green porous matrices with inhibited solubility thanks to the gelation of alginate.
