Abstract:

The water-retention hydrogel composites were synthesized by the free-radical polymerization depending on the order of addition filler of the protein hydrolysate. As the filler was used protein hydrolysate, ‘Biostim’, obtained by processing cattle hides. The influence of gelation time on the synthesis parameters of hydrogel compositions was investigated. It is found that the gelation time of the sample without filler is 2–2.5 times longer than filled of hydrogel compositions. The structural characteristics of polymer composition by TGA, DSC and atomic force microscopy were determined. FTIR spectra found decrease in the intensity of vibrations of (-COO-) groups, indicating about additional ionic interactions. Decrease the beginning evaporation temperature of polymer composites with increase concentration of protein filler, indicating the destruction of the ordered structure of the polymer material revealed by thermogravimetric analysis (TGA). The influence of various media, such as distilled water, saline solution, and buffer solutions at differents pH on the swelling behavior of hydrogels was also assessed. Maximum swelling capacity showed sample prepared with order of addition filler at the end of synthesis (Scheme I). The kinetics of the release protein hydrolysate from the polymer matrix was measurement by spectrophotometric method. The synthesized hydrogel composites with protein hydrolysate and improved physicochemical properties are of practical interest as water-retaining materials for increasing of crop the yield in agricultural.

Abstract:

This paper describes the problem of obtaining a hydrolysate from animal industry byproducts. A new innovative protein-containing product has been created to stimulate the growth and development of berry and fruit crops. The paper describes a technique for a plant treatment with a hydrolysate invented, its concentrations being determined. We have studied the chemical composition of fruit and berry raw materials in a native form after rapid freezing and refregiration. The possibility of creating a new confectionery product made from quick-frozen berries treated with a stimulator is predetermined.

Abstract:

In this article describes the current problems of aquaculture. As a new material for feeding fish pond serves biocomposite based on protein hydrolysates and natural polymers. Also disclosed is a method of forming the proposed mother. Studies have been conducted biocomposite molecular weight and amino acid composition of the initial protein products.
