摘 要：本文以花椒籽为原料，以此对花椒籽进行预处理、压榨、精炼，在课题组基础上，对样品酸价、过氧化值、磷含量、水及挥发性物质含量进行测定。通过单因素实验考查了精制温度、时间、压力、流量等因素对精制花椒籽仁油出油率的影响，实验结果表明：最佳精制温度为40℃，精制时间为6h，精制压力为25Mpa，精制流量为80Pv。在此条件下，压榨花椒籽仁毛油的精制出油率达到80.04%，经过碱炼精制的样品酸价为1.3(KOHmg/g)，过氧化值为0.12(g/100g)，磷含量为1.0(mg/100g)，含水量及挥发性物质为1.20(g/100g)，油脂色泽澄清透明，感官品质优良达到国家食用油标准。 关键词：花椒籽仁油 超临界CO2 精制 |

Abstract epper seeds as raw material, this preprocessing, press pepper seeds, refining,In the research group on the basis of, on the the sample acid value, peroxide value, phosphorus content, water and volatile substances content of were measured. By single factor experiments examined the refining temperature, time, pressure, flow and other factors on the refined pepper seed kernel oil oil yield,The experimental results show that: Best refining temperature to 40 ° C, the refined time 6h, refined pressure to 25MPa refined flow of 80Pv, Under this condition, press pepper seed crude oil refined oil yield of 80.04%, after alkali refining purified samples of acid value of 1.3 (KOH mg / g),The peroxide value is 0.12 (g/100g), phosphorus content of 1.0 (mg/100 g), water content and volatile matter 1.20 (g/100g), oil color, clear and transparent, the senses high quality meet the national edible oil standard.Keywords: epper seed kernel oil; Supercritical CO2; Refined |
