| Popis: | The results of researches of influence of protein-mineral supplements on quality indicators of butter cookies are presented. It is described, that the supplements are used as a multifunctional ingredient, which on the one hand enriches the finished product with digestible calcium compounds, on the other - performs a number of technological tasks and improves the consumer characteristics of butter cookies. The purpose of the study was to determine the effect of protein-mineral supplements on a number of physicochemical, consumer characteristics and safety indicators of butter cookies. The study of the following physicochemical parameters of the quality of butter cookies was conducted: mass fraction of moisture, wettability, alkalinity, calcium content, including total and protein-bound. It is established, that with the content of supplements up to 5.0% of the flour weight, all the above indicators meet the established requirements. With the content of suppements at the level of 6.0… 7.0%, there are limit values of such an indicator as wettability, which is undesirable to ensure the appropriate porous structure of the product. Based on the obtained data, it can be stated, that 5.0% of the use of supplements is the limit rational content in the composition of butter cookies. The organoleptic analysis proved the high characteristics of the developed products in comparison with traditional ones. In products with supplements, there was an improvement in the structure of the product in the cut and its color. This is ensured by the stabilization of the emulsion by the supplement during the manufacture of products and by peculiarities of its chemical composition. Studies of safety indicators allowed to establish less intensive dynamics of accumulation of primary oxidation products (peroxides) in samples of flour and butter products with supplements in comparison with control. The best microbiological stability of products with supplements is also proved. Due to the bacteriostatic effect of the supplements, less intensive accumulation of microflora during storage was achieved. On the basis of the conducted researches the expediency of using up to 5.0% of protein-mineral supplements in the composition of flour and butter products for enrichment of finished products with digestible calcium compounds, improvement of organoleptic characteristics and safety indicators have been established. |
