| 摘要: |
| 研究了葡萄种子微波干燥对葡萄种子油物理化学性质的影响。结果表明，微波处理提高了葡萄种子油的产率，增加了油的粘度、共轭双烯值、过氧化值和皂化值，降低了叶绿素和类胡萝卜含量（K410和K670值）及对甲氧基苯胺值。醇洗葡萄种子去单宁处理降低了油色素值，提高了共因子双烯值、对甲氧基苯胺值、过氧化值和皂化值。 |

| Abstract: |
| The effect of microwave and air-drying of grapeseeds on the physic-chemical quality of their oils were investigated.Microwave treatment improved oil yield and increased viscosity,conjugated dienes,peroxide values and saponification value while reducing chlorophyll (K670) and carotenoid (K410) pigment contents and p-anisidine values.Removal of tannin by washing grapeseed with alcohol resulted in oil with low pigment content (K410 and K670 values),high peroxide value and diene,p-anisidine,and saponification values.The results demonstrate the impact of using microwave heating in producing oil from grapeseed. |
