METHOD FOR PRODUCTION OF FRIED ACORNS Russian patent published in 2012 - IPC A23F5/44 A23L3/16 

FIELD: food industry.

SUBSTANCE: invention relates to vegetable dehydration and food-concentrates industry and may be used for production of coffee beverages with acorns addition. The method envisages raw material inspection, sorting, washing, peeling, cutting, frying with superheated steam under atmospheric pressure. Frying with superheated steam is performed in four stages: at the first stage acorns cut into cubes with linear size up to 3-5 mm are heated up to 345 K, treated with superheated steam with a temperature equal to 423 K at a rate of 1.85 m/s during 8 minutes; at the second stage treatment is performed with superheated steam with a temperature equal to 433 K at a rate of 1.3 m/s during 8 minutes; acorns cubes heated till the temperature is equal to 355 K; at the third stage treatment is performed with superheated steam with a temperature equal to 443 K at a rate of 0.8 m/s during 2 minutes, acorns cubes heated till the temperature is equal to 358 K; at the four stage treatment is performed with superheated steam with a temperature equal to 453 K at a rate of 0.35 m/s during 6 minutes; acorns cubes heated till the temperature is equal to 378 K; then acorn cubes fried till final moisture content equal to 3% are milled for further usage.

EFFECT: invention allows to produce fried acorns with high content of valuable thermolabile substances, intensify the process of production and enhance its heat effectiveness.
