The invention discloses a preparation method of a pre-cooked Fotiaoqiang frozen bag. The preparation method includes the following steps: cooking bone soup by adopting a high-temperature high-pressureshort-
time processing mode, then adding a plurality of materials such as abalones, sea cucumbers, scallops, shark lips, fish maws,
shiitake mushrooms, tendons,
quail eggs, duck gizzards, etc., boiling the mixture with soft fire to obtain a Fotiaoqiao product, cooling the Fotiaoqiao product to
room temperature, adding
scallop skirt
hydrolysate, carrying out packaging by adopting a high temperatureresistant
steaming / boiling bag, then
quick freezing the bag at -35 to -45 DEG C for 50-60 minutes to obtain a pre-cooked Fotiaoqiao frozen bag, and putting the pre-cooked Fotiaoqiao frozen bag in a refrigerator (-18 DEG C) for
frozen storage. The pre-cooked Fotiaoqiang frozen bag is high in
nutrient value, simple and convenient in
processing technology and easy to realize industrial production; and a proper amount of the
scallop skirt
hydrolysate is added to inhibit the growth and recrystallization of
ice crystals, so that the method can maintain
water retention capacity,
solubility and otherfunctional characteristics of proteins better, and can prevent the product from darkening in the process of freezing storage and from affecting the eating quality.
