摘要
通过低温液压压榨技术研究火麻仁油脂的提取工艺。首先对火麻仁原料进行筛选,然后通过单因素实验研究压榨的时间、温度、压力以及投料量对火麻仁出油率的影响,采用正交实验对液压压榨火麻仁油的工艺进行优化,并对火麻仁油进行质量评价。结果表明,广西巴马产的去壳火麻仁原料含油率高达56.53%,且以液压压榨出油率最高,其压榨油脂品质最佳。液压法压榨火麻仁油的最佳工艺为:投料量500 g,压榨压力50 MPa,压榨温度70℃,在此最佳条件下火麻仁油的出油率为44.01%。经检测,所得的火麻仁油含有大量的不饱和脂肪酸,感官指标和理化指标均符合食用植物油标准。
This paper studied the extraction technology of hemp seed oil using low temperature hydraulic pressing method. Firstly, to screen the raw materials of hemp seed, and then the effect of time, temperature, pressure and material mass on the oil yield of hemp seed was studied through a single-factor experiment. The optimal technological parameters of cold pressed hemp seed oil were investigated by orthogonal experiments, and the quality of the hemp seed oil was evaluated. The results showed that the oil content of the shelled Bama hemp seed produced in Guangxi was as high as 56.53%, and the hydraulic press had the highest oil yield, and the quality of the pressed oil was the best. The optimal process for hydraulic pressing of hemp seed oil is as follows： material mass of 500 g, pressure of 50 MPa, temperature of 70℃. Under optimal conditions, the oil yield of hemp seed oil was 44.01%. Meanwhile, hemp seed oil was rich in unsaturated fatty acids, its sensory analysis and physicochemical properties were attained the edible vegetable oil standard.
