abstract
The invention relates to a production process of dry powder of nutritional active substances of edible engineering maggots, belonging to the technical field of protein extracted from natural resources for human consumption. At present, the development and utilization of fly maggot protein resources is limited to the formation of regenerated protein which can be used as feed for poultry animals, and no protein products for human consumption have been formed. According to the invention, edible engineering maggots are used as raw materials, and the nutritional active substance dry powder is prepared through production processes such as separation treatment, cleaning, filtering, pretreatment, refrigeration, grinding, centrifugation, pasteurization, homogenization treatment, re-centrifugation, spray drying treatment, dry powder collection, packaging, microwave sterilization and the like. The product can reach the specified nutritional index, hygienic index and sensory index, and contains a variety of trace elements. The invention designs a set of systematic industrial production technology for the production of dry powder of nutritional active substances of fly maggots, and provides a high-level and widely applied way for the development and utilization of fly maggot resources.
Sovereignty terms
The invention relates to a production process of nutritional active dry powder of edible engineering maggots, which takes edible engineering maggots as raw materials and is characterized by comprising the following steps: (1) separation treatment: preliminary separation in a light box: pouring the engineering maggots with feed cultivated for three days into the light box, and optically separating the engineering maggots from the feed; Mixing the photolysed engineering maggots with a salt solution with a specific gravity of 1.02, separating in a specific gravity separator, and collecting the engineering maggots; (2) cleaning, filtering, rinsing with small flow water, desalting and dewatering, filtering, (3) pretreatment and refrigeration, and soaking the filtered engineering maggots in a mixed protective solution of sodium sulfite and trace elements for 65,438+/-0 minutes. (4) grinding, that is, before grinding, the engineering maggots are washed again with clear water, and then mixed solution of trace element NaHSO3 is added, with the weight ratio of1:0.075; Evenly stirring, grinding in a colloid mill, (5) centrifuging, collecting ground maggot slurry, centrifuging in a high-speed large-capacity freezing centrifuge or an electric centrifuge, taking filtrate and discarding residues, (6) pasteurizing, (7) homogenizing, putting the pasteurized filtrate into a homogenizer for treatment, (8) centrifugally spray drying, and then freeze-drying or drying the homogenized active liquid.
