Proteolytic enzymes for improving the properties of meat products from non-traditional raw materials

In this scientific article the influence of enzymatic treatment on the quality of meat products from nontraditional raw materials (camelina, horse meat, mutton, beef) was studied. Bromelain (0.5-0.2%), papain (0.1-0.3%) and ficin (0.1-0.5%) as well as their combination were used as enzymes. To improve functional and technological characteristics, a multicomponent brine containing plant components (sea buckthorn powder, pumpkin powder and goji berry extract, rosemary extract), plant enzymes, phosphates and protein hydrolysates were used. The results showed that the use of enzymes contributed to the softening of the meat structure, improving the juiciness and tenderness of the product. The most pronounced effect was observed in samples treated with papain, while ficin had the greatest effect on mutton and beef. The study of pH dynamics showed that without enzyme treatment, pH increased to 6.67 after 5 days, indicating initial signs of spoilage. At the same time, the combined application of enzymes kept the pH at a stable level (6.20), which helped to extend the shelf life of the product. Thus, the use of proteolytic enzymes in combination with multicomponent brine improves the texture, organoleptic characteristics and functional and technological properties of meat products, which can be recommended for industrial production.
