Problems solved by technology

[0003] In the new era, with the continuous development of the market economy, the supply and demand of agricultural products have undergone tremendous changes, and the guiding role and binding force of market demand on agricultural development have continued to increase. As a result, the prices of primary agricultural products produced by many farmers are relatively low, and it is difficult to sell them. The increase in income and production is slow, and a large area of ​​agricultural products is unsalable.

Abstract

The invention discloses a high value-added whole-grain food deep processing technology, and relates to the technical field of food processing. In the processing process, the method comprises the following steps of: preparing fermentation mother liquor: mixing dried amaranth stems with water according to a mass ratio of 1: 3-1: 10, soaking for 12-36 hours, and filtering to obtain a filtrate; mixingthe cereal food and the filtrate according to a mass ratio of 1: 1-1: 5, performing sealed fermentation for 24-48h, and performing filtration to obtain the fermentation mother liquor; pickling: mixing the cereal food with the fermentation mother liquor according to a mass ratio of 1: 3-1: 10, standing for 24-36 hours, and performing suction filtration to obtain pickled cereals; freezing and squeezing: freezing the pickled cereals, and performing heat-preservation squeezing for 10-80min under the condition that the pressure is 3-15MPa, so as to obtain squeezed pickled cereals; and performing vacuum frying: adding the squeezed and pickled cereals into a vacuum frying machine, and performing vacuum frying at the temperature of 75-120 DEG C after the vacuum degree reaches 0.1 MPa or below, soas to obtain the high value-added whole-grain food.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a high value-added whole grain food deep processing technology. Background technique [0002] Deep processing of agricultural products refers to the process of deep processing various animal and plant products and related materials produced in agriculture to meet the needs of the market and consumers. The deep processing of agricultural products includes not only the processing of various industries and materials of agriculture, forestry, animal husbandry, and aquatic products, but also the processing and effective utilization of wild animal and plant resources. The various products obtained from the deep processing of agricultural products have a vital impact on our daily production and life, and are widely used in various fields such as industry, pharmaceuticals, animal feed, renewable energy, production and life. In the process of deep processing of agricultural produ...
