Application of Chrysomya megacephala larvae as oil insects

Abstract

The invention belongs to the fields of food or bioenergy and develops a new oil source, i.e. Chrysomya megacephala larvae as oil insects. Oil can be obtained by drying aged and mature Chrysomya megacephala larvae with hot blast or microwave and then carrying out a squeezing method (i.e. delivering the Chrysomya megacephala larvae into a screw-type press when the Chrysomya megacephala larvae is hot so as to squeeze oil out). The oil can be used as raw material oil for food, chemical industry and biodiesel. The oil content of the Chrysomya megacephala larvae is 20-21 percent, and the oil extracted from the Chrysomya megacephala larvae is proved to contain various unsaturated fatty acid needed by human bodies based on nutrition constituent analysis and is high-quality healthy oil; the Chrysomya megacephala larvae have short growth cycle which is only 4-5 days and can be cultivated under high density conditions with extremely small occupied area and yearly-rate oil production higher than 20t / acre per year in each acre of land; and the production can be carried out in an industrial factory building without occupying cultivated land area; and the oil contains no toxin and is safe and reliable with simple extraction process.

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
