<p>FIELD: food industry. ^ SUBSTANCE: invention relates to food industry. According to the proposed method the products are preliminarily heated in dry atmosphere till a temperature is lower than the temperature of saturated vapour at the selected value of water vapour treatment pressure. Treatment with water vapour is performed in humid air tight atmosphere under a pressure within the range of 0.15 - 4.0 bars and at a temperature within the range of 55C -144C during 1-30 minutes. Condensate from the product surface is removed by way of subsequent vacuum drying under a pressure within the range of 0.15 - 0.01 bars during 2-20 minutes. The food products are represented by oil seeds, almond nuts, hazelnuts, pecan nuts, walnuts, peanuts, offal, grits, coffee, cocoa. ^ EFFECT: proposed invention allows to develop a method wherein water absorption and quality changes of the food products are minimised while heat treatment conditions are optimised. ^ 4 cl, 2 dwg, 1 tbl</p> |
