TỐI ƯU HÓA ĐIỀU KIỆN SẤY PHUN DỊCH TRÍCH LY NẤM VÂN CHI (Coriolopsis aspera) TẠI VIỆT NAM

Tóm tắt

The objectives of studying the effects of spray drying conditions such as inlet drying temperature,
carrier content, feed flow rate on powder recovery efficiency, moisture content, reduction of free
radical scavenging capacity, total flavonoid content, total polyphenol content, total triterpen content
(RSA, TFC, TPC, TTC) of spray drying powder. Performance results for optimized experiment design.
The one-factor experiment, the Box-Behnken mathematical model design was optimized in the spray
drying process of the Coriolopsis aspera. The optimal parameters of spray drying with ethanol extract
to extract TTC content are at least as follows: inlet drying temperature 1330C, carrier content 16% (w
/ w), feed flow 22.5ml / min then The prediction results of the target functions are 42,201% powder
recovery efficiency, 2.936% powder moisture and 9.224% RSA reduction, 2.358% TFC reduction,
4.12% TPC reduction, 0.989% TTC reduction. The control results were exactly the same as the
predicted results. That means the predicted values are consistent with the optimal values.
