Application of housefly maggots as oil material insects

Abstract

The invention belongs to the food field or the field of bio-energy and develops a new oil material source-oil material insect housefly maggots. Grease can be obtained by carrying out hot air or microwave drying on aged housefly maggots and then using the press method (sending the housefly maggots into a screw press when the housefly maggots are still hot and pressing out the grease) for pressing. The grease can be used as a raw material oil for food, chemical industry and biodiesel. The oil content of the housefly maggots is 13-17%, and the grease extracted therefrom contains a variety of unsaturated fatty acids required by a human body through the analysis of nutritional ingredients, thereby being a high-quality healthy oil material; the growth cycle is short which is only 4-5 days, the occupied area is very small, the cultivation can be carried out under the high-density condition, the annual oil production per mu can achieve about 20t / mu year, and the cultivation can be carried out in an industrial plant without occupying the cultivated land area; and the grease is non-toxic, safe and reliable, and the extraction process is simple.

Description

technical field [0001] The invention belongs to the field of food or bio-energy, and in particular relates to a new oil source—oil insects. Background technique [0002] At present, the world's three major oil crops are rapeseed, soybean and peanut. These three types of crops are rich in oil content, especially rapeseed and peanut, the oil content reaches 40-50%. However, these three major oil crops have been difficult to meet the growing population's demand for oil, mainly because of their long growth cycle, such as spring dawn rape growth cycle 60-130 days, winter small rape 130-290 days, soybean 90 days -140 days; at the same time, these crops occupy a large area of ​​cultivated land, and the planting process is easily disturbed by weather and various pests and diseases. 34 kg / mu·year, peanut 80-90 kg / mu·year, in today's scarcity of arable land, this will undoubtedly increase the burden on land resources; in addition, because these oil crops themselves contain certain t...

However, these three major oil crops have been difficult to meet the growing population's demand for oil, mainly because of their long growth cycle, such as spring dawn rape growth cycle 60-130 days, winter small rape 130-290 days, soybean 90 days -140 days; at the same time, these crops occupy a large area of ​​cultivated land, and the planting process is easily disturbed by weather and various pests and diseases. 34 kg / mu·year, peanut 80-90 kg / mu·year, in today's scarcity of arable land, this will undoubtedly increase the burden on land resources; in addition, because these oil crops themselves contain certain toxins, such as rapeseed contains sulfur Glucosides (mustard toxins), soybeans contain antitrypsin and thrombin, peanuts are prone to moisture and mildew, and are prone to produce aflatoxins with strong carcinogenicity. When used as edible oils, they need to be treated in multiple stages, otherwise the safety will be compromised. It is not guaranteed, which also increases the requirements for processing technology to a certain extent, and the production cost is higher

[0003] Although all countries are currently devoting themselves to the development of new oil crops. For example, my country is studying the use of woody plants that can grow recyclably as oil crops. However, this also requires a large amount of land resources, and has low production efficiency, high cost, and difficulty in collection. The low quality of oil plants and the difficulty of removing phytotoxins all restrict the practical application of research results in this field
