Abstract

The invention discloses a wheat bran oil production technology using subcritical butane extraction, and belongs to the field of food engineering. Wheat bran undergoes subcritical butane extraction multiple times, and the obtained extract liquid undergoes reduced pressure distillation to remove an extractant to obtain the wheat bran oil containing methyl palmitate, methyl linoleate and methyl oleate. The wheat bran is cyclically extracted by adopting a subcritical butane technology, and technologic optimization researches of factors affecting the yield of the wheat bran oil are carried out by adopting Box-Benhnken center combination response surface test design in order to obtain optimum technologic parameters; and a gas chromatograph-mass spectrometer (GC-MS) is used to analyze the fatty acid components of the wheat bran oil obtained through the subcritical extraction in order to provide reference for the development and the utilization of wheat bran resources. The wheat bran oil production technology is simple, allows the extraction rate to reach up to 86.92%, is suitable for industrial application, and provides a new way for the further utilization of the wheat bran.

Description

technical field [0001] The invention relates to the field of food engineering, in particular to a production process for subcritical butane extraction of wheat bran oil. Background technique [0002] Wheat bran is the residual part after extracting wheat flour and germ in the milling process, which accounts for 14% to 19% of the wheat mass. Bran contains rich amylase, protein, phytic acid and other active compounds, and has very prominent If the bran can be fully utilized for deep processing and comprehensive utilization, it will have high economic and social benefits. [0003] In recent years, studies on wheat bran extract at home and abroad have shown that wheat bran extract can effectively control blood sugar and reduce the risk of cardiovascular disease in diabetic patients; regulate the effectiveness and retention of minerals; activate the body to use selenium as The main oxidative stress protection mechanism; various physiological functions such as anti-tumor and immu...
