Abstract
The paper presents the results of the study of the influence of additives based on polysaccharide hydrocolloids on the degree of carotenoid loss and the organoleptic properties of molded minced meat products after steaming and deep-frying. Additives based on the following hydrocolloids have been used: sodium alginate, carrageenan, a mixture of guar and xanthan gum. It has been shown that with the addition of each of these hydrocolloids, there is a significant reduction in the degree of carotenoid loss and the total mass of the product. A positive effect of hydrocolloids on the organoleptic characteristics of finished molded products, in particular the “cut appearance”, has also been noted. When frying in oil, the smallest losses of total weight (14.0%) and carotenoids (49.1%) from the initial content have been observed when sodium alginate has been used. For the case of steaming semi-finished products, the smallest losses of total mass (9.8%), oil phase (34.2%) and carotenoids (42.0%) from the initial content are observed when using sodium alginate. The obtained data on changes in the degree of carotenoid loss correlated with changes in the type of semi-finished products in the cut. In general, a statistically significant decrease in carotenoid losses, regardless of the type of heat treatment used, has been observed in the series: no additives → gum → carrageenan → sodium alginate. Smaller losses corresponded to hydrocolloids with the highest melting point of the gels they formed. The article makes an assumption about the primary influence of mass transfer processes during heat treatment on the degree of preservation of carotenoids in the composition of molded fish products.
