Preparation method for coarse cereal-fruit-nut-vegetable food

Abstract

The invention discloses a preparation method for a coarse cereal-fruit-nut-vegetable food, which comprises the following steps: (1) whole grains are sequentially extruded by double screws and baked, so that a crisp whole grain material is obtained; (2) sugar and water are boiled into syrup; (3) after being uniformly mixed, the syrup and the crisp whole grain material are baked and cooled, so that an aromatic and crisp whole grain material is obtained; (4) the aromatic and crisp whole grain material, dehydrated fruit granules, roasted nut granules and vacuum-fried vegetable granules and / or pressure difference-puffed vegetable granules are mixed, and thereby the nutritional food mixed with coarse cereals, fruits, nuts and vegetables is obtained. The nutrition of the prepared food is balanced and scientifically formulated, the coarse cereal-fruit-nut-vegetable food can provide nutrient substances which are needed by the human body daily, moreover, the taste of the food is aromatic and crisp, the original tastes of the grains are kept, and in combination with the fruits, the nuts and the vegetables, the taste of the product has the original taste of the grains, the aroma of the fruits, the after-taste of the nuts and the faint scent of the vegetables.

Description

technical field

[0001] The invention relates to a preparation method of miscellaneous grains, in particular to a preparation method of miscellaneous grains, fruits, nuts and vegetables, and belongs to the technical field of food processing. Background technique

[0002] Miscellaneous grains usually refer to grain and bean crops other than the five major crops of rice, wheat, corn, soybean and potato. Mainly include: sorghum, millet, buckwheat (sweet buckwheat, tartary buckwheat), oats (naked oats), barley, millet, millet, barley, grain amaranth and kidney beans (kidney beans), mung beans, adzuki beans (red bean, red bean), Broad beans, peas, cowpeas, lentils (lentils), black beans, etc.

[0003] Grains are rich in nutrients. For example, oats are rich in protein; millet is rich in tryptophan and carotene; beans are rich in high-quality protein; sorghum is rich in fatty acids and rich in iron; potatoes contain carotene and vitamin C. In addition, coarse grains also have th...
