中文摘要:
      为了探明立地对油茶籽出油率及油茶籽油品质的影响,以9个立地的低温压榨油茶籽油为样品,测定油茶籽出油率及油茶籽油的理化性质、感官品质、脂肪酸组成、功能性成分含量及氧化诱导时间,分析坡向、坡位因子对油茶籽出油率及油茶籽油品质的影响。结果表明:立地对油茶籽出油率及油茶籽油的过氧化值、碘值、皂化值、感官品质、功能性成分含量及氧化诱导时间均具有明显影响,对油茶籽油的酸价、脂肪酸组成无明显影响。说明立地是影响油茶籽出油率及油茶籽油品质的重要因素。
英文摘要:
      In order to ascertain the effects of site on the oil yield of oil-tea camellia seed and the quality of oil-tea camellia seed oil, nine sites’ low-temperature pressed oil-tea camellia seed oils were used as samples to determine the oil yield of oil-tea camellia seed and the physicochemical properties, sensory quality, fatty acid composition, functional ingredient content and oxidation induction time of oil-tea camellia seed oil. Then the effects of slope orientation and slope position on the oil yield of oil-tea camellia seed and quality of oil-tea camellia seed oil were analyzed. The results showed that site had significant effects on the oil yield of oil-tea camellia seed, and the peroxide value, iodine value, saponification value, sensory quality, content of functional components and oxidation induction time of oil-tea camellia seed oil, while it had no significant effect on the acid value and fatty acid composition of oil-tea camellia seed oil,which indicated that site was an important factor affecting the oil yield of oil-tea camellia seed and the quality of oil-tea camellia seed oil.
