Soybean oil refining technology research:
Edible vegetable oil has been the indispensable a necessity in our diet.With the rapid economic development, the improving of people's living standard, the daily consumption of vegetable oils have also risen sharply.The quality of the vegetable oil quality also more and more get more attention.At the same time, it also carry out higher demands on our oil refining industry.This study on the basis of traditional soybean oil refining technology combined with previous studies, degumming and bleaching process of soybean oil refining technology was improved, the phospholipase Lecitase Ultra used in the soybean oil degumming;And to study the ultrasonic on phospholipase Lecitase Ultra removal soybean oil the influence of nonhydratable phospholipids;The silicone used in soybean oil decoloring, using silica gel and clay combination of decolorization of oil test, the influence factors in the process of silica gel used for oil decoloring into line.palm oil plant sterilizing station (http://www.palmmill.com/Products/proa/)main research is as follows: (1) through the single factor experiment research conducted by enzyme concentration, reaction time, reaction temperature, pH value and water content on the phospholipase Lecitase Ultra removal soybean oil effect of nonhydratable phospholipids.Selected on the basis of single factor, enzyme concentration, digestion temperature, digestion time, pH value, four factors as the independent variable, in response to the oil after degumming of phosphorus content value, according to the principle of central composite design, the phospholipase Lecitase Ultra removal soybean oil nonhydratable phospholipids response surface experiment was carried out, using the software Expert Design7.0 trials for data processing, phosphorus (P) content (X1), reaction time and enzyme concentration (X2) (X3), reaction temperature, pH value (X4) quadratic multinomial regression equation between the P = 316.08275 +...
