Food encapsulation plant

Abstract

This article shows an installation for encapsulating food products. Ensuring food security, the constant satisfaction of the population's needs for basic foodstuffs, is one of the main directions of ensuring the national security of any state. There is still an open question of obtaining high-quality capsules with properties and characteristics that dissolve in the desired environment, retain the therapeutic effect and at the same time meet the requirements of the consumer (ease of use, efficiency, reasonable cost). An installation for producing microcapsules was made of such parts: they are Mercury ATX Switching Power Supply-450W power supply; aquarium tube; glass washer pump; variable resistor with 10K switch; DC-dc DC voltage stabilizer, LM2596S module; gelatin, sodium alginate solution; electromagnetic mixer; plastic sprayer for spraying water (nozzle); calcium chloride solution. There are many technologies of the encapsulation process. Capsules can be obtained by drip, disk spraying methods. In this work, sodium alginate and gelatin were selected as the encapsulating material. A gelatin solution with the addition of sodium alginate was used as an aqueous solution of the gel-forming mixture. The best option is the composition of capsules containing 0.5% alginate and gelatin, the solution should be used at a temperature of 40° C. Capsules were obtained by the drip method. Capsules obtained from 0.5% sodium alginate were soft, with a smooth surface, with an average size of 2,0×10-3м.
