【摘要】 利用油脂氧化稳定性测定仪,对复合天然抗氧化剂延长储备花生油储存期的效果进行了研究。花生油氧化稳定性测定条件为:进气流量5.5psi,样品质量5.00g,加热温度130℃。选择迷迭香提取物为主抗氧化剂,复合抗氧化剂配方为0.03%迷迭香提取物+0.01%抗坏血酸+0.005%柠檬酸+0.005%TBHQ。此配方抗氧化效果接近于TBHQ。更多还原

【Abstract】 The effects of natural antioxidant compound on prolonging the shelf life of reserve peanut oil was studied by oxidative stability instrument.The operational parameters of the instrument were:air flow rate5.5psi,sample weight 5.0g,temperature 130℃.And the results showed that rosemary extracts were the most suitable natural antioxidant which could be used as the main antioxidant.The optimum formula of the antioxidant compound was as follows:rosemary extracts 0.03%,ascorbic acid 0.01%,citric acid 0.005%,TBHQ 0.005%.The antioxidant capacity of this compound was as same as TBHQ.更多还原
