摘要
对国产芝麻样品和进口芝麻样品及其相应压榨芝麻油的组分和品质进行对比分析。结果表明:进口芝麻较国产芝麻的子粒稍大且略显饱满;国产芝麻和进口芝麻的粗脂肪含量略有差异,国产芝麻的粗蛋白含量高,草酸和灰分含量低;国产芝麻较进口芝麻压榨芝麻油的色泽无明显差别,但磷脂含量、酸价、皂化值、过氧化值较低;国产芝麻油的抗氧化成分含量和氧化稳定性均好于进口芝麻油;国产芝麻油和进口芝麻油的脂肪酸组成基本一致,均在芝麻油国标范围内;进口芝麻压榨芝麻油的香味稍逊色于国产芝麻油。
The composition and quality of domestic and imported sesames and their oil processing properties were compared.The results showed that the kernels of imported sesames were larger and more plump than the domestic varieties.The fat content of domestic and imported sesames had no significant difference,but the protein content of domestic sesames was higher than the imported ones.The imported sesames were rich in ash and oxalic acid.The phospholipid,acid value,saponification value,peroxide value of domestic sesames was lower than imported sesames.Antioxidant components content and oxidative stability of domestic sesame oils were higher than imported kind.Fatty acids composition of sesame oil from different cultivated areas had no significant difference.The favor of domestic sesame oil was better than the imported variety.
