Development of technology for obtaining encapsulated probiotics

Abstract

   One of the priority areas of the modern food industry is the development of functional food products that have a regulatory effect on physiological functions, biochemical reactions and psychosocial behavior of a person through the normalization of his microecological status. Scientists assign a special role in functional nutrition to fermented milk products with probiotics, which have a more pronounced functional effect on the human body, due to the complex action of probiotics. However today traditional production technologies face some problems, in particular, the problem of preserving and delivering viable probiotic cells to the gastrointestinal tract in order to display therapeutic properties. In this regard, the use of methods for encapsulating probiotics to obtain capsules and their application in the technology of fermented milk products for functional purposes is relevant. This article discusses the technology for obtaining encapsulated probiotics. To obtain encapsulated probiotics, several types of biopolymers were used: amidated pectin, sodium alginate, and gelatin. To substantiate the selected encapsulating materials, experimental studies were carried out to determine the possibility of capsule formation of amidated pectin, sodium alginate and gelatin at a concentration of 1 %, 2 %, 3 %, as well as the ratio of gelatin and sodium alginate 1/1 %, 2/1 %, 3/1 %, 4/1 %.
