This article mainly analyzes the influence of two different processing techniques on the quality of fly maggot powder by studying the comparison of the processing technology of hot air drying and positive air freeze drying and combining its determination of nutrients. The maggot powder yield is 5% higher, the sensory score is 10 points higher, the protein content is higher than the hot air drying method 7% -10%, and the moisture content is lower, according to the experimental results prove vacuum freezing The sensory evaluation, nutritional composition and protein quality of drying process are higher than those of hot air drying process. In terms of nutrient composition determination, six groups of fly maggot powders established in the previous three layers of chicken manure, meat chicken manure, and egg meat mixed chicken manure were measured and analyzed respectively. The nutrition of protein and fat in A1, B1, and C1 was dried by hot air The value is lower than that of the maggot powder samples A2, B2 and C2 obtained by vacuum freeze-drying. The maggot powder obtained from the three kinds of chicken manure is comprehensively compared, and it is obvious that the nutrient content of fat, protein, and chitin compounds obtained by broiler feeding and processing is higher than that of the other two. The content of He and ash is lower than that of the other two groups. In the determination of amino acids, the essential amino acids accounted for the content of amino acids in 6 groups of determination samples

In this paper, mainly by studying the comparison of hot air drying and positive air freeze-drying processing process and combined with the determination of its nutritional content, the effect of two different processing processes on the quality of fly powder, vacuum freeze-drying method compared to the hot air drying method in the rate of fly powder is 5% higher, high in the sensory score of 10 points, the content of protein is higher than hot air drying method 7%-10%, and the content of water is lower, according to the experimental vacuum drying results, the results of the analysis of the results of the analysis of the Protein quality is higher than hot air drying. In terms of nutrient determination, the first three types of egg and chicken manure, meat with chicken manure, egg meat mixed chicken manure set up 6 groups of fly powder were measured and analyzed, hot air drying A1, B1, C1 in protein, fat nutritional value is lower than vacuum freeze drying samples A2, B2, C2. The comprehensive comparison of fly powder obtained by the three kinds of chicken manure clearly shows that the nutrient content of the chicken as the bait is raised and processed to obtain the spout powder fat, protein, chitin compound situ mixtures are higher than the other two, while the content on water and ash is lower than the other two groups. In the determination of amino acids, 6 groups of essential amino acids accounted for amino acid content in samples

In this paper, by comparing the processing technology of hot air drying and air freezing drying, and combining with the determination of its nutritional components, the influence of two different processing technologies on the quality of fly maggot powder is analyzed. Compared with hot air drying, vacuum freeze drying method has a higher yield of 5% in fly maggot powder, a higher sensory score of 10 points, and a higher protein content of 7% in hot air drying method- According to the experimental results, the sensory evaluation, nutritional composition and protein quality of vacuum freeze-drying were higher than that of hot air drying. In the aspect of nutritional composition determination, the six groups of maggot powder established by three kinds of egg chicken manure, meat chicken manure and egg meat mixed chicken manure were determined and analyzed. The nutritional value of hot air drying A1, B1 and C1 in protein and fat was lower than that of vacuum freeze drying A2, B2 and C2. The results showed that the contents of fat, protein and chitin were higher than those of the other two, while the contents of water and ash were lower than those of the other two groups. In the determination of amino acids, the proportion of essential amino acids to amino acids in six groups of samples was determined<br>
