Application of black soldier fly larvae as oil-crop insect

Abstract

The invention belongs to the fields of foods or bioenergy and develops a new oil source, i.e. black soldier fly larvae as an oil-crop insect. Oil can be obtained by using a compression method (larvae is fed into a screw-type press while hot to press oil out) after black soldier fly adult and larvae are dried by hot wind or microwave. The oil can be used as raw oil for eating, chemical industry and biodiesel. The oil content of the black soldier fly larvae is 30-35 percent, through analyzing the nutritious components of the oil, and oil extracted from the black soldier fly larvae contains various unsaturated fatty acids needed by human bodies, thereby being high-quality health oil. The black soldier fly larvae has short growth period which is only 20-30 days and very small floor area, can be cultured under the condition of high density, reaches the oil production per mu of 4t / mu.year, can be carried out in an industrial factory building without occupying land area, contains no toxin, is safe and reliable, and has 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
