碳离子束辐照对紫苏油品质和理化性质的影响
利用兰州重离子研究装置(HIRFL)提供的^12C6+针离子束辐照紫苏干种子,吸收剂量分别为40Gy、80Gy和120Gy,剂量率约4Gy/min,探讨重离子束辐照对紫苏M1代紫苏油品质和理化性质的影响。结果表明:随着碳离子束吸收剂量的升高,和正常对照组相比,紫苏油粗蛋白含量降低,总糖含量升高;紫苏油中碘值降低,皂化值升高,但过氧化值、酸值和色泽变化不大;紫苏油脂肪酸组成中油酸含量逐渐升高,亚麻酸、月桂酸、棕榈酸和硬脂酸含量都逐渐降低,但亚油酸含量变化不大。提示:碳离子束辐照后,M1代紫苏的紫苏油主要理化指标变化不大,但不饱和程度有所升高,有利于紫苏油品质的改善。...

| Bibliography: | Perilla-oil, Carbon ion beams, Quality, Irradiation The dry seeds ofperillafrutescens(L.) were irradiated with ^12C6+ ion beams with a dose of 0, 40, 80, and 120 Gy, respectively, at a dose rate of 4 Gy/min generated from the Heavy Ion Research Facility in Lanzhou (HIRFL). The results showed that M1 generation quality characteristics of perilla seeds had some changes after irradiation with ^12C6+ ion beams, such as crude protein yields decreasing while total sugar content increased. The iodine value decreased while the saponification value increased, but the acid value, peroxide value and colour of perilla-oil had little change. Furthermore, these findings suggested that carbon ion beam irradiation increased the contents of oleic acid, and decreased the contents of palmitic acid, lauric acid, stearic acid and linolenic acid, but hardly affected the contents of linoleic acid. All these data suggest that ^12C6+ ion beam irradiation could increase the "degrees of unsaturation" of perilla-oil to improve its qualit  |
