METHOD FOR MANUFACTURING SNACKS FROM PLANT RAW MATERIAL Russian patent published in 2022 - IPC A23L19/00 A23L19/18 

FIELD: food industry.

SUBSTANCE: invention relates to the food industry, in particular to a method for the production of snacks from vegetable raw materials. The method is characterized by the fact that preliminary preparation of vegetable raw materials is carried out, the prepared raw materials are placed in maltitol syrup with a solids content of 35-40% and kept for 4-6 hours at room temperature. Then the raw material is frozen in a chamber with an air temperature of -35°C to -40°C for 20-40 minutes until the temperature inside the product reaches -12°C to -15°C. After freezing, the raw material is placed in a vacuum dryer and treated in oil for 10-15 minutes at a pressure of 0.095-0.098 MPa and a temperature of 60°C-100°C. At the same time, ultrasound is applied with a frequency of 20-30 kHz and a specific power of 400-1000 W until the humidity in the product reaches 4-8%. Further, excess oil is removed by centrifugation or blowing and draining.

EFFECT: invention makes it possible to obtain a product with a long shelf life while maintaining organoleptic properties.
