Abstract
The invention relates to a preparation method for an instant lotus seed and tremella soup block. The preparation method comprises the following steps: putting tremella into water and boiling with big fire for 10-15 minutes; directly adding washed dried lotus seeds and boiling with the big fire for 5-10 minutes; boiling with gentle fire for 10-20 minutes; adding 0.1-0.3% of lotus seed starch while a mixture is hot; adding white granulated sugar or rock candy, and agitating and dissolving; mixing to be uniform; instantly freezing the lotus seed and tremella soup at temperature ranging from -30 DEG C to -40 DEG C until the central temperature ranging from -20 DEG C to -25 DEG C is reached; freezing for 4-6 hours; freezing and drying by using a program temperature raising method, wherein drying and sublimation parameters are as follows: the cabin pressure is 130-140Pa, and the temperatures and the time are -10 DEG C (2 hours), -5 DEG C (5 hours) and 0 DEG C (2 hours): drying and decomposing, wherein the cabin pressure is 50-70Pa, the temperatures are 10 DEG C, 20 DEG C, 30 DEG C and 40 DEG C and the time is 2 hours; sealing, sterilizing and packaging by inflating nitrogen. The preparation method is small in energy consumption, low in cost and long in guarantee period; the previous flavor and nutrition of foods are kept and the instant lotus seed and tremella soup block can be eaten after being blended with cold boiled water.
