When foreigners make bread, they should crush breadworms and add them to the bread. One is to increase the nutrition, and the other is to increase the fragrance. People like to eat it, so it is called a bread bug. So it's also called a bread bug. With high nutritional value, it is called "the king of animal protein feed". Its protein content is 47%, fat content is 23%, carbohydrate content is 23%, and its nutritional components are comprehensive, ranking first among all kinds of animals and plants. It is rich in 19 amino acids and other indispensable nutrients for fish, especially vitamins B2, E, riboflavin and unsaturated fat. It is one of the ideal bait for raising ornamental fish. Bread deep-processed products are widely used. Breadform is a kind of high-quality protein feed instead of fish meal, and its nutritional components are equivalent to those of imported high-quality fish meal, but its production cost is much lower than that of fish meal. Nereis is a kind of high-quality edible oil, and it is also an additive oil for health products, cosmetics and transformer oil. Foods, beverages and condiments developed from fresh bread worms or defatted proteins are constantly emerging, such as bread worm compound supplements. Some large enterprises are optimistic about insect protein food and actively participate in the development. China Agricultural University's scientific research achievements on the comprehensive development and utilization of breadworm resources have come out, and samples of canned breadworm pupae have been made quickly, so as to investigate the market and orders. The bread worm slough is a high-quality raw material for producing chitin, and its calcium content is much lower than that of shrimp and crab shells, which greatly reduces the processing difficulty. Chitin has broad application prospects in functional food, medical supplies, health care products and environmental protection materials, textiles, degradable film production and other fields. Thorax dung is a good organic fertilizer and can also be used as coarse feed for livestock and poultry. Bread-like feces are extremely dry, contain almost no water and have no odor. It is the only kind of dung like fine sand in the world, so it is also called sand dung (also called dung sand), which is very convenient to transport. According to laboratory analysis, 25% nitrogen can be used as feed for pigs and fish. , phosphorus 1.04%, potassium 1.4%, and contains seven trace elements of zinc, boron, manganese, magnesium and copper. Can be directly used as fertilizer. After application, it can not only increase soil fertility, increase crop yield and improve the quality of agricultural products, but also reduce agricultural production costs, improve soil structure, improve agricultural ecological environment and promote the sustainable development of planting industry. At present, the supply of real high-efficiency bio-organic fertilizer products in the market is not large, which is unstable and can not meet the needs of high-efficiency agricultural production. Therefore, the high-efficiency bio-organic fertilizer produced with insect manure as the main raw material has a good market prospect. In addition, insect feces contain high crude protein.
