不同富硒方法对茶油品质特性及功能性成分的影响
Effects of different selenium-rich methods on quality characteristics and functional components of Camellia oleifera oil
摘要
Abstract
Based on the two methods of fertilizing selenium and biochemistry of selenium enriched selenium,selenium content,sensory quality,physicochemical index,fatty acid composition and functional components in Camellia oleifera oil were determinated to investigate quality characteristics and functional ingredients of the two methods.The results showed that selenium content in camellia oleifera was 0.11 mg/kg and 0.49 mg/kg,respectively.The two methods meet national standards,and biochemistry method was significant higher than fertilization.Camellia oleifera oil by the fertilizer method had better sensory quality.Acid value,peroxide value were reduced by the two method,but the iodine value,saponification value and fatty acid composition of tea oil had no significant difference.There was no significant difference in the content of stigmasterol,sitosterol and tea polyphenols of the two methods,and the alpha tocopherol and squalene content in the camellia oleifera oil of biochemistry method were decreased obviously.Above all,the two methods significantly improved the content of selenium in Camellia oleifera,which was up to the selenium-rich levels,and selenium-enriched fertilization method had a long selenium-rich period and the tea oil had better sensory quality.Biochemistry selenium-rich method can get the arms quickly and effectively,but which can damage some of the functional components of the Camellia oleifera.关键词
