Potato starch the extrusive modified bulking - up TU U 00383403.001 - 98

Extrusive starch is one of the most multifunction raw products due to its property to form gels and thickeners. Depending on properties, extrusive starch is used for giving to products of the corresponding texture, look (state), humidity, consistence, and also stability in storage time. Potato, wheat, rice and corn extrusive starches of production of JSC Kiev Krakhmalopererabatyvayushchy Combine use: for bodying of kissels, fruit porridges; in confectionery - cookies, cakes, rahat lakoum; as additive in pasta (in the ratio 1: 3 to macaroni flour); meat and fish semi - finished products. Tapioca extrusive starch forms more viscous and transparent pastes, in comparison with corn and wheat starches. Therefore it is widely used for production of ketchups, and also sauces and low - in - fat mayonnaise. With the technical purpose corn and potato extrusive starch is applied in the paper industry, textile and pharmaceutical industry, and also at production of construction mixes.

Extrusion is characterized by simultaneous impact on the processed material of moisture, heat, mechanical tension of different look. The raw materials loaded into extruder represent the disperse weight in which there is certain amount of freely connected moisture. In process of advance on the working camera of the car and as a result of allocation of thermal energy of internal friction, intensive external power supply, various in size and the direction of mechanical tension, material is condensed - pressed - plasticized, there is the first phase transition of solid body to the present freely connected moisture in solution liquid in liquid. As a result of high pressure and temperature moisture is in solution in superheated state (pressure in extruder can reach 25 MPas, the water boiling point already at 10,0 MPas exceeds 300 °C, temperature of ekstrudiruyemy material is in limits of 120 - 170 °C), molecules of superheated water, possessing large supply of kinetic energy, are capable to diffuse more effectively in native structure of material, than it occurs in the conditions of normal pressure even a lot of water. There is formation of difficult conglomerates of molecules of water and biopolymers in which bonds are thermodynamic unstable. The plasticized material is squeezed out from the car via the drosseliruyushchy device. Sharp pressure difference is resulted by flash, "explosion - like" evaporation of moisture including the structure of material diffusing inside. The native structure of material collapses. There is the second phase transition of solution liquid in liquid in gas solution in solid body, the product acquires foamy structure. Process provides ready - made products of certain form, structure and physical and chemical properties. Extrusion is highly effective, wasteless, short - term technology process, and the extruder is considered by many researchers as the universal biochemical reactor. Essential ingredients of the raw materials used in the extrusive technology "EXPERT of GROUPS, LTD. " is high - molecular polymers - the starches having reactive groups in the structure. Uniqueness of extrusive method, the used "EXPERT of GROUPS, LTD. ", consists in opportunity not only to use wide range of types, traditional for our country, and properties of starch - containing raw material, but also to receive products of various structure and form (products, ready - to - serve, products of baby medical and preventive foods, semi - finished products, treated starches and t). The extrusive processing of starch and starch - containing raw material used by us allows to receive food, completely ready - to - serve (snack products, krispies, flakes, etc. ), instant products (semi - finished products of chips, puddings, drinks and kissels, soups not demanding cookings).
