摘要
花生中脂肪含量较高,受储存条件影响宜发生化学反应,导致脂肪酸值升高,对影响花生脂肪酸值测定的因素进行研究。结果表明,浸出溶剂采用石油醚(沸程60~90℃),粉碎粒度0.15 mm,提取温度25℃,提取时间15 min,所测脂肪酸值结果较为可靠。
Peanuts are high in fat. Peanuts is affected by the storage condition,which lead to higher levels of fatty acids. In this paper,the factors affecting the value of peanut fatty acid are studied. Experiments show that,the results of the measured fatty acid are more reliable,when leaching solvent using petroleum ether（boiling range 60~90 ℃）,granularity of 0.15 mm,extraction temperature 25 ℃,extracting time 15 min.
