Abstract
PURPOSE: To prepare frozen white asparaguses without change in flavor, color, etc., by cooling heat-treated white asparaguses, and quickly freezing the heat- treated white asparaguses with an inert gaseous refrigerant.
CONSTITUTION: White asparaguses sorted and washed in the first step (A) are washed with water in a water tank 2 the second step (B), dipped in boiling water 3 for several minutes and heat-treated in the third step (C). The heat treatment prevents the change in flavor, color, etc. of the white asparaguses due to the inactivation of enzymes. In the fourth step (D), the heat-treated white asparaguses are quickly dipped in cooling water and cooled to a given temperature of 10°C or below. In the cooling treatment, the oxidation of nutriments, growth of germs, etc. by the contact with air are prevented to keep the high quality of the asparaguses, etc. In the fifth step (E), the white asparaguses free from the surface moisture after the cooling treatment are contained in freezing dishes 5, 5,... in a given amount and sent to a freezing apparatus 6. The white asparaguses 1, 1,... are quickly frozen at -50°C or below by a gaseous refrigerant.
