Decompression oil-frying method for food products

摘要

A quick decompression oil-frying method for producing food products. The method comprises uniformly heating a food material to a suitable temperature in an atmosphere of a pressure which ranges between normal pressure and a raised pressure, rapidly decompressing the atmosphere to such a low pressure that the water contained in the food material is evaporated at a temperature below the temperature of the food material and at such a rate as to permit the expansion of the food material, drying the food material in an oil of a temperature substantially equal to the temperature of the food material and restoring the normal pressure.
