The result showed that the optimal extraction technology conditions of aloe gel juice were : blanching treatment of 90℃/5min, color retention treatment of 0.05% sodium erythorbate+0.1%CA, enzymolysis of 0.05% Pectase under 45℃ for 1h.
ResultsThe optimum extraction process of the total saponins of Gymnema sylvestre has been established as follows:the concentration of ethanol 70%,ratio of material to liquid 1:6,extraction time 3h,2 times.
The results showed that the optimal extracting technology was different among the skins of selected fish. Under the optimal extraction conditions, the extraction ratios of collagens from these skins were 36.57%, 30.58%, 35.14% and 45.17% respectively, while the corresponding yields were 8.93%, 8.52%, 9.03% and 6.50% respectively.
