In order to realize above-mentioned purpose, the preparation method of product instant solid fresh soya-bean milk of the present invention is as follows:
At first utilize routine techniques to prepare soya-bean milk, be about to soybean soaking to weight be about original weight 2-2.5 doubly after, add water filtration while grinding with stone mill and become pure fresh soya-bean milk, pour into to boil in the pot and got final product preferred 4 minutes in 3-5 minute;
The soya-bean milk of cooling is packed in the container, put into the freezer quick-frozen and become solid, and the temperature of each entity is lower than-18 ℃; Preferably-20 ℃.Carry out the vacuum dehydration drying then, vacuum in its vacuum storehouse is lower than 100pa, dry process is carried out as follows: heating is 10 hours the heating in vacuum temperature was risen to 85 degrees centigrade in 0.5 hour after, heating is 2 hours after again temperature being reduced to 75 degrees centigrade in 1 hour, again temperature was reduced to 60 degrees centigrade of heating 2 hours in 1 hour, again temperature is reduced to 50 degrees centigrade of heating 1 hour in 0.5 hour, again temperature was reduced to 40 degrees centigrade in 0.5 hour.
Then that drying is good solid fresh soya-bean milk is packed; Preferred damp-prrof packing;
The preparation method of above-mentioned instant solid fresh soya-bean milk, the vacuum when wherein vacuum dehydration is dry is lower than 100Pa; Preferred vacuum is 60Pa;
Above-mentioned cryodesiccated solid fresh soya-bean milk water content is for being not more than 3% (percentage by weight); Preferred 3%;
The preparation method of above-mentioned instant solid fresh soya-bean milk, wherein said solid fresh soya-bean milk carries out in the packaging step, uses In Aluminium Foil Packing;
The preparation method of above-mentioned instant solid fresh soya-bean milk wherein is refrigerated to subzero 18 degrees centigrade of soya-bean milk central temperature; Preferred subzero 20 degrees centigrade.
Product of the present invention is compared with product in the prior art has following distinguishing feature: adopt Lyophilisation technique for making, product has the characteristics of nutrition free of losses, instant and long shelf-life.
The beneficial effect of product of the present invention is as follows:
After product of the present invention dashes with boiling water, can keep the local flavor of traditional fresh soya-bean milk to greatest extent, and not loss of nutrition, mouthfeel is better.Make product of the present invention both nice, can save time again, filled up the blank in market.
