Technical Field

The invention relates to the technical field of coarse grain snacks, in particular to a snack mainly made of coarse grains and a processing method thereof.

Background

The coarse grain is relative to fine grains such as polished rice and flour which are usually eaten by people, and mainly comprises corn, purple rice, sorghum, oat, buckwheat, wheat bran and various dry beans such as soybean, green bean, red bean, mung bean and the like. The coarse food grains have various types and high nutritive value, and the nutrients contained in the coarse food grains are respectively long. The coarse grain has simple processing process, and retains many nutritional ingredients not contained in the fine grain. From the aspect of nutrient components, most of coarse grains have relatively low protein content, and starch, cellulose, mineral substances and B vitamins are rich. The nutrient components can be summarized as follows: 1. contains protein: the situation of protein contained in different coarse grains is different, and the oat is rich in protein; legumes are also rich in protein and are high quality protein, with the remainder of the coarse grain protein being less than oat and soy. 2. Contains fat: the fat content in the coarse food grain is not high, and the content of corn, purple sweet potato and the like is very low. 3. Contains carbohydrate: the content of carbohydrate in the coarse grain is not very high, and the carbohydrate content of buckwheat and oat is more than that of the rest coarse grain. The coarse food grain contains rich insoluble cellulose, and is favorable for ensuring the normal operation of the digestive system. 4. Contains vitamins, which are much higher than polished rice and polished flour: among various staple foods, the refined white rice has the lowest vitamin content and is inferior in quality. Because of its distinctive characteristics, the cereal has its vitamins and minerals concentrated mainly in the outer layers. The coarse food grain is rich in vitamins.

At present, with the continuous improvement of living standard of people, consumers want to contain more kinds of nutrient components in food while tasting delicious food, and pay more attention to the effects of preserving health and conditioning. Therefore, a new technical solution needs to be provided.
