通过依据国家相关标准测定不同贮藏温度下栝楼籽的酸价、脂肪酶活动度、过氧化值、TBA值及VE的保留率以研究贮藏温度对栝楼籽油脂酸败的影响.结果表明:温度是影响栝楼籽油脂酸败的重要因素.在0℃和5℃的低温条件下,能明显抑制栝楼籽的脂肪酶活动度,降低酸价,延缓过氧化值和TBA值的升高,减少VE的消耗,有效延缓栝楼籽的油脂酸败.
通過依據國傢相關標準測定不同貯藏溫度下栝樓籽的痠價、脂肪酶活動度、過氧化值、TBA值及VE的保留率以研究貯藏溫度對栝樓籽油脂痠敗的影響.結果錶明:溫度是影響栝樓籽油脂痠敗的重要因素.在0℃和5℃的低溫條件下,能明顯抑製栝樓籽的脂肪酶活動度,降低痠價,延緩過氧化值和TBA值的升高,減少VE的消耗,有效延緩栝樓籽的油脂痠敗.

To examine the effect of storage temperature on the rancidity of raw Trichosanthes kirilowii oil,the oil stored at different temperatures (0,5,15,25℃) was analyzed for acid value,lipase activity,peroxide value,TBA value and VE retention rate according to relevant national standards for edible oils at intervals of 1 month,Results showed that the stability of Trichosanthes kirilow oil was affected notably by environmental temperature and higher storage temperatures resulted in the fast quality change.However,storage temperatures of 0℃ and 5℃ significantly inhibited lipase activity,delayed the elevation of acid value,peroxide value and TBA value,and reduced the loss of vitamin E,thereby obviously delaying the rancidification of raw Trichosanthes kirilowii oil.
