Study on Conjugated Linoleic Acids Preparation by Microwave Irradiation

Abstract

Abstract: The conjugated linoleic acid (CLA) preparation from linoleic acid of corn germ oil was investigated in glycerin solvent system under microwave irradiation. The molecular structures of end products were determined by UV and FT-IR spectrum. The results showed that they contained cis- and trans- double bonds. Compared with conventional heating with oil bath,microwave irradiation was an effective way to prepare CLA. Through the analysis of impact factors and results of orthogonal test,the optimal preparation conditions of CLA were gotten,CLA yield above 95%.

Key words: , microwave irradiation； conjugated linoleic acid； isomerization； preparation condition；
