In this work, we propose technology for processing protein-containing products - beans into protein components for nutrition, also the use of waste after protein in the energy industry. The technology includes several stages: extraction, separation of fractions, precipitation, concentration. The optimal conditions for each stage of the technological process were selected (the ratio of the sample to the extracting substance, pH, water module, volume of precipitant, the volume of washing fractions, drying conditions...

At the present stage of development of the biotechnological industry, the most promising objects are enzymes of the oxidoreductase class, which are capable of catalyzing redox processes. One of the most studied enzymes of this class is horseradish root peroxidase. Its immobilization on various carriers allows the biocatalyst to be reused in various technological processes. In recent years, magnetic nanoparticles have been increasingly used as effective carriers of enzymes.In this work, we study the oxidation of 2,...

This paper presents the results of a study of the hydrolysis of microcrystalline cellulose in a subcritical water medium. The influence of temperature, time, cellulose/water ratio, cellulose particle size, and other parameters on the hydrolysis process was studied. The influence on the process of pretreatment of aqueous dispersions of cellulose with ultrasound was studied. It was shown that the optimal processing time is 30 min (~ 150 kJ). Over a given period of time, destruction and partial hydrolysis of the amor...

In this study, a procedure was developed for the synthesis of WO3-containing catalysts based on zeolites of the ZSM-5 type. Zeolites with different Si/Al ratios and different numbers of acid sites were used: ZSM-5-CVM, ZSM-5-CVN and ZSM-5-Acros. The synthesized catalysts were characterized and tested in the reaction of the conversion of fructose and glucose to 5-hydroxymethylfurfural and levulinic acid. It was shown that the introduction of tungsten (VI) oxide into the composition of ZSM-5 leads to a noticeable in...
