Method for producing insect proteins and grease by efficient conversion of crop straws through multi-stage cooperation of insects

Abstract

The invention discloses a method for producing insect proteins and grease by efficient conversion of crop straws through multi-stage cooperation of insects. The method involves a tenebrio molitor conversion system and a Wuhan hermertia illucens (L.) conversion system. In the processes of the two conversion systems, insect biomasses can be obtained, and the insect grease can be extracted from the insect biomasses and used for producing biodiesel oil; the obtained insect proteins can be used as protein feed additives. The problem of pollution to the environment due to waste crop straws is solved, and the urgent need of the livestock and aquaculture industries for feed proteins is met; furthermore, food safety can also be guaranteed, the dependency on fossil energy is relieved, and wastes are turned into treasures to obtain considerable economical benefits. According to the method, the conventional physical and chemical pretreatment processes are effectively avoided; the method is absolutely environment-friendly, cost-saving and high in additional value; by the combination with a natural insect biodegrading system, efficient use is realized; straw biomasses are directly converted into biological energy, and animal feed protein raw materials are produced at the same time.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for producing insect protein and oil by utilizing insect multi-stage combined high-efficiency transformation of crop straws. Background technique [0002] As a big agricultural country, China has a long history of crop cultivation. According to statistics, China's total crop straw output in 2011 was close to 700 million tons, of which corn straw was 220 million tons, accounting for about 20%-30% of the world's total crop straw output. However, most of the crop straws are burned on the spot or directly returned to the fields, which are not fully utilized, which not only pollutes the environment, but also causes a lot of waste of lignocellulose resources. If this waste resource can be used correctly, it can not only reduce environmental pollution and bring considerable economic benefits, but also alleviate the energy crisis caused by the shortage of renewable ener...
