METHOD FOR PRODUCING LONG-TERM STORAGE PLANT FILLER Russian patent published in 1999 - IPC

FIELD: food-processing industry, in particular, manufacture of products containing long-term storage filler. SUBSTANCE: method involves washing processing equipment with hot water and washing agents; sterilizing cooker and feeding pipelines at temperature of 90-150 C for 5-40 min with overheated water or steam under pressure equal to 5-40 of gage atmosphere pressure; blowing with sterile gaseous agent, such as air and/or nitrogen, and/or carbon dioxide, and/or mixture of these gases and simultaneously cooling processing equipment to 60-85 C; introducing prepared fruit or plant raw material, sugar, water, thickening agent and other components into cooker; pressurizing cooker; vacuumizing mixture to pressure equal to 0.2-0.8 of absolute atmosphere; providing thermal treatment for 30-60 min; upon termination of thermal treatment process, equalizing pressure in cooker to atmospheric pressure by supplying sterile air at pressure not exceeding 1.5 of gage atmosphere pressure; introducing aromatizers and dying agents; repeatedly pressurizing cooker and heating to 85-115 C without deaeration; holding mixture while continuing to mix it for 3-30 min and immediately cooling it to 35-40 C by supplying sterile air into cooker; discharging ready product under aseptic conditions into sterile package filled with sterile gaseous agent. Method allows aseptic filler for yoghurt and other food products to be obtained without usage of preservatives for single stage. EFFECT: increased efficiency, improved quality of filler and wider range of products obtained by using this filler. 25 cl, 2 dwg, 3 ex
