Processing method for food cockroach

Abstract

The invention provides a processing method for a food cockroach, belonging to the technical field of cockroach processing. The processing method comprises the following steps: collecting artificially bred cockroach imagoes; soaking the collected cockroach imagoes in a treatment fluid for 12 to 16 h; taking the soaked cockroach imagoes out from the treatment fluid and rinsing the cockroach imagoes with clear water; taking the rinsed cockroach imagoes out from clear water and carrying out draining; placing the drained cockroach imagoes in an environment with a temperature of -40 DEG C and maintaining the cockroach imagoes at the temperature for 3 h; slowly heating the cockroach imagoes to -2 DEG C for lyophilization, wherein slow heating lasts for 5 h; then heating the cockroach imagoes to 25 DEG C and maintaining the cockroach imagoes at the temperature for 3 h; and taking the cockroach imagoes out and crushing the cockroach imagoes to 90 meshes so as to obtain food cockroach powder. The processing method for the food cockroach can remove poisonous and harmful substances in the cockroach without destroying nutritional components therein; the prepared food cockroach powder can be directly mixed with other feeds for feeding of other animals or directly fed as foodstuff; and compared with cockroach powder processed by using traditional methods, the food cockroach powder prepared in the invention has the advantages of no loss of nutritional components and a higher nutritive value.

Description

Technical field: [0001] The invention relates to the technical field of cockroach processing, in particular to a method for treating food cockroaches. Background technique: [0002] Most people hate cockroaches, and some people spend a lot of time and effort trying to get rid of them. But few people know that cockroaches can be a fortune. [0003] Roasted cockroaches can be used as a medicine for promoting muscle growth and hemostasis, and promoting wound healing, which is found in ancient prescriptions. Because cockroaches can be used as medicinal materials, protein resources, and feed for livestock and poultry and aquaculture, it has good economic value, so a large number of cockroaches are cultivated artificially. However, in the prior art, cockroaches are used as raw materials for feed, and the dried cockroaches are directly ground into powder, which is directly mixed and used in feed. Although cockroaches also have high nutritional value and medicinal value, they also...

Problems solved by technology

However, in the prior art, cockroaches are used as raw materials for feed, and the dried cockroaches are directly ground into powder, which is directly mixed and used in feed. Although cockroaches also have high nutritional value and medicinal value, they also have There are also some harmful substances, which also carry a large number of bacteria and viruses, so they should not be used directly as food.

At present, cockroach powder is dried and ground into powder, which can achieve the purpose of sterilization during the drying process, but the harmful substances in the cockroach body have not been disposed of

Moreover, drying at high temperature will also lead to the loss of nutritional value of cockroach powder.
