Influence of thistle grist on organoleptic, physico-chemical and microbiological parameters of kefir


Keywords: unctional products, kefir, thistle grist, technology

Abstract

Modern complex environmental conditions put forward the urgent need to improve the nutritional structure of the population at the expense of improving the quality, biological value and taste of the products. That is why the purpose of the work was to justify the use of thistle grist on kefir technology. In particular, the effect of thistle pellet on the organoleptic, physicochemical and microbiological parameters of kefir has been investigated. It was established that it had a homogeneous consistency with a broken clot and a color from white to cream with interspersed grist. Increasing the dose of thistle grist to 3% and 4% has led to a taste with sharply pronounced flavor of thistle and to a brown color with a pronounced thistle content. The kefir viscosity of 2.5 mg per kg changes over the seven days of storage, although it remains high enough for 8 days, namely 47 seconds. The growth of the viscosity of kefir with thistle grist is due to the hygroscopic properties of grist, resulting binds moisture free product. The analysis of microbiological parameters in the storage of kefir with thistle grist allows us to conclude about the satisfactory sanitary condition of the new product and its harmlessness for the consumer's health.
