| Outline of Final Research Achievements |
This study aimed to investigate control mechanisms of the composition of triacylglycerol (TAG) molecules and crystal properties of pork fat, and to modify physical traits of pork fat. When compared with other mammals’ adipose tissue, the gene expression patterns of isoenzymes involved in TAG synthesis were quite different only in pig fat, thus leading to unique fatty acid compositions of positions sn-1, 2 and 3 of TAGs seen in pork fat. We also established Raman-spectroscopic indices to evaluate crystal properties of pork fat, and applied to analyze crystal formation of pork fat during chilling of carcasses and microscopic distribution of crystal in porcine adipose tissues. Moreover, differed cooling speed provided different hardness values and appearances of pork fat.
