Annotation: This article discusses the idea of developing a functional product that exhibits biologically active, bifidogenic properties and a strong antioxidant effect. The authors propose the formulation of sea buckthorn marmalade with the addition of immobilized probiotics. The jelly-fruit marmalade formulation is used as a control sample; apple puree is replaced with sea buckthorn concentrate, sugar and molasses with fructose. In experimental samples, various methods of introducing probiotics are used and their viability in the finished product is further evaluated. According to the organoleptic characteristics, the samples have a pleasant taste, smell, original color, gelatinous consistency. The best viability was shown by microorgan isms immobilized by incorporation into the gel.

Annotation: Modern measuring instruments – a technical device, the purpose of which is to measure the unit of physical quantity. But do not confuse measuring instruments with indicators, the main purpose of indicators is to detect the presence of the measured physical quantity. Measuring instruments are an integral part of human life.

Annotation: The article is devoted to the task of automating the assessment of the electrical safety level of electrical installations based on the determination of the electrical resistivity of soil layers ρ in specific climatic conditions. The soil ρ value depends on many factors, which can vary significantly during the year. Therefore, the decision was made using modeling based on one of the areas of artificial intelligence: fuzzy logic.

Annotation: The article discusses the biotechnological aspects of the use of medusomycete as a producer of chemicals in cosmetology. Organoleptic and chemical studies of a tea drink using various growth substrates were performed.
