Description

Freezing buckwheat skin of beancurd and production method thereof
Technical field
The invention belongs to frozen food manufacture field, relate to a kind of freezing buckwheat skin of beancurd and production method thereof.
Background technology
Buckwheat is important cereal crops and resources of medicinal plant, is divided into two kinds of sweet buckwheat and bitter buckwheats.According to estimates, the current world sweet buckwheat total output 500~6,000,000 t, Chinese total output approximately 750,000 t, after ranking Russia, occupy the 2nd, the world.And bitter buckwheat is peculiar by China, total output approximately 300,000 t.Though buckwheat belongs to little ancestor crop in Grain in China crop, but nutritional labeling is unique, essential amino acid pattern can improve biological value with Major Cereal is complementary, and contains the bioactive ingredients such as flavones that other cereal do not possess and rutin, has high medicine and health care and is worth.Facts have proved: long-term edible buckwheat, can significantly improve body immunity, the modern diseases such as control and assisting in treating hypertension, coronary heart disease, apoplexy are had to outstanding effect.
In China's buckwheat producing region, always there is the tradition of making buckwheat foods, and of all shapes and colors, local flavor is different.More representationally comprise that noodle prepared from buckwheat, pancake, He Le, bowl stick together, fiber crops food, skin of beancurd etc.Wherein, buckwheat skin of beancurd is Jingzhou Prefecture's traditional-handwork special product, rises in Wang Jiaqiao town, Songzi City (the raw ramie region of rivers and lakes), liked by the local common people.The raw material of making buckwheat skin of beancurd mainly contains buckwheat, rice, potato, mung bean.Traditional method is to be polished into starchiness after buckwheat, rice are soaked with boiling water, adds in proportion potato, green starch, after stirring, paste is spread out to cutification in heat pot, takes the dish out of the pot after cooling and is cut into silk, and airing is air-dry.At present, existing semi-automatic production line has partly substituted traditional-handwork manufacture craft, but substantially make flow process, has no innovation.Generally speaking, in order to extend the shelf-life of skin of beancurd, still follow traditional drying mode, adopt outdoor airing mode to carry out air-dry.Whole dry run need to constantly be carried out batch (-type) to material and stirred, and very easily causes skin of beancurd break bar, fragmentation; Meanwhile, because drying time and degree are restricted by weather conditions, if meet with overcast and rainy wet weather, skin of beancurd airing is insufficient, likely cause product not resistant to cook, very easily stick with paste soup, even moldy metamorphism, has a strong impact on skin of beancurd edible quality.
Summary of the invention
