摘　　要：将车间精炼的合格一级大豆油,泵进灌装车间油罐或户外油罐群,在1~2 d后出现返色返酸现象。为更好地控制大豆油的返色返酸,从原料品质、储存条件、制油过程、精炼过程分析大豆油返色返酸原因,从设备配置、调整工艺操作参数等方面提出控制措施。为了达到企业包装油内控标准酸值(KOH)≤0.08 mg/g和色泽≤Y10/R1.3,精炼车间控制出油色泽≤Y7/R0.7、酸值(KOH)≤0.05 mg/g,基本能满足市场消费者的需求。The qualified first grade refined soybean oil coming from refinery plant is translated into the finished oil tanks in the filling plant or the tank farm, and the color and acid reversion will be shown in the oils during storage for 1-2 d. To better control the color and acid reversion of soybean oil, the reasons for the color and acid reversion of soybean oil from the quality of raw materials, storage conditions, oil production process, and refining process were analyzed, and provided control measures in terms of equipment configuration and adjustment of process operation parameters.In order to achieve the enterprise internal packaging oil control standards with the acid value less than or equal to 0.08 mgKOH/g and the color less than or equal to Y10/R1.3, the oil from refinery plant should be controlled in the color less than or equal to Y7/R0.7 and acid value less than or equal to 0.05 mgKOH/g to basically meet the requirement of consumer.
