Abstract:

In the dry substance of Parasarcophaga crassipalpis (PC) and Aldrichina grahami (AG), the protein contents were more than 60% in the maggots, and more than 70% in flies. The amount of essential amino acid [g·(100 g)^-1 protein] was between 46 and 59, higher than 35, the standard content of FAO/WHO. The ratios of the essential to total amino acid were higher than standard mode 40% of FAO/WHO. Among essential amino acids, all of the contents were higher than standard mode except Valine and Methionine plus Cysteine. The grease contents were around 20% in maggots, and less than 10% in flies. The ratios of unsaturated fatty acid to total fatty acid were more than 70% no matter in maggots or in flies. Essential fatty acid was Linoleic Acid, its contents were more than 40% in maggots and around 17% in flies. In PC and AG maggots, the contents of iron and zinc were opulent, the results of iron were 684 and 664 μg·g^-1 and the zinc were 170.5 and 158.0 μg·g^-1 respectively. The calcium contents were not more than perfect soybean, the amount were 0.46% and 0.48% respectively. The phosphorus contents were higher than normal milk powder, the amount were 0.57% and 0.54%. The ratios of calcium to phosphorus were 0.81 and 0.79 respectively, both higher than ideal value 0.5.
