Problems solved by technology

The entire drying process requires continuous intermittent turning of the material, which can easily lead to broken and broken bean curds; at the same time, because the drying time and degree are restricted by weather factors, if the bean curds are not fully dried in rainy and humid weather, it may be As a result, the product is not resistant to boiling, it is easy to paste the soup, and even moldy and deteriorated, which seriously affects the eating quality of the bean curd

Abstract

The invention discloses a frozen buckwheat bean curd skin and a production method thereof. The frozen buckwheat bean curd skin consists of the following raw materials in parts by weight: 30 to 50 parts of rice flour, 25 to 45 parts of wheat flour, 15 to 20 parts of buckwheat flour, 2.5 to 10 parts of bean flour, 0.05 to 0.5 part of edible gum and 90 to 220 parts of water. The frozen buckwheat bean curd skin obtained by the method has long shelf life, is not pasted after being rehydrated, is delicate in mouthfeel, smooth and soft, and has the specific fresh scent of buckwheat and a certain health-care function. Compared with the traditional process, the production process disclosed by the invention has the advantages that the quality of product produced through the method is greatly improved and the industrialized degree is greatly improved.

Description

technical field [0001] The invention belongs to the field of frozen food processing, and relates to a frozen buckwheat bean curd and a production method thereof. Background technique [0002] Buckwheat is an important food crop and medicinal plant resource, which can be divided into sweet buckwheat and tartary buckwheat. It is estimated that the total output of sweet buckwheat in the world is 5-6 million tons, and the total output of China is about 750,000 tons, ranking second in the world after Russia. Tartary buckwheat is unique to China, with a total output of about 300,000 tons. Although buckwheat is a minor crop in China's food crops, it has unique nutritional components. The essential amino acid pattern can complement the main grains to increase the biological value. It also contains bioactive components such as flavonoids and rutin that other grains do not have, and has extremely high medicinal properties. use and health value. Practice has proved that long-term co...
