Technology of fish semi-finished products using antimicrobial compositions with organic acids and salts

The actual problem of business is the low quality of fish raw materials due to the delay in deliveries from the manufacturer. The search for new technological solutions to extend the shelf life of fish raw materials due to the reduction of microbiological contamination is relevant. A technology is proposed for the production of natural fish semi-finished products using antimicrobial compositions based on organic acids and salts. Chilled carcasses, semi-finished products of trout (fillet with skin) and antimicrobial agents based on organic acids and salts (Dilactopolydon (DLP) and Dilactin Forte Plus (DFP) were used as objects of research. The choice of the most effective concentration of the DLP solution for processing trout carcasses was carried out using the mathematical method of a single-factor experiment and the Statgraphics Centurion computer program. Regression equations with high correlation coefficients are obtained. The most effective concentration of DLP during processing of trout carcasses before cutting into a piece of fillet with peel was set at 2% when the ratio of raw material to the additive solution was 1: 1 and aged for 20 minutes...
