摘要: 以红松籽仁为原料,以无水乙醇为提取溶剂,优化高速匀质-微波辅助提取红松籽油的工艺,考察了匀质速度、匀质时间、液料比、微波温度、微波功率及微波时间对红松籽油提取率的影响,最终确定了红松籽油最佳提取条件为:匀质速度12 000 r·min-1,匀质时间120 s,液料比20 mL·g-1,微波温度60℃,微波功率700 W,微波时间50 min。在上述条件下,红松籽油最优提取率可达60.3%。利用GC-MS对得到的红松籽油的脂肪酸成分进行了分析,其主要成分为棕榈酸、皮诺敛酸、亚油酸、反-13-十八碳烯酸、顺-13-十八碳烯酸、硬脂酸,不饱和脂肪酸含量高达85.55%,其中松籽油所含有的特异性不饱和脂肪酸-皮诺敛酸含量可达13.65%。此外,对该工艺提取得到的红松籽油的抗氧化活性及理化性质进行了评估,发现红松籽油清除DPPH自由基能力强,其IC50值为0.095 4 g·mL-1。此外,红松籽油过氧化值和酸值较低,碘值较高,表明红松籽油是一种品质优良的天然油脂。

Abstract: In this work, ultra turrax-microwave assisted extraction process was conducted to extract oil from Pinus koraiensis using ethanol as the extraction solvent. The effects of homogenization speed, homogenization time, liquid-solid ratio, microwave temperature, microwave power, and microwave time on the oil yield were investigated. The optimal conditions for the oil extraction from P.koraiensis seed were obtained as follows:homogeneous speed 12 000 r·min-1, homogeneous time 120 s, the ratio of liquid to material 20 mL·g-1, microwave temperature 60℃, microwave power 700 W and microwave time 50 min. Under the above conditions, the optimum oil yield was 60.3%. The fatty acid composition of P.koraiensis seed oil was analyzed by GC-MS, and the main components were identified as linoleic acid, stearic acid and palmitic acid. The contents of unsaturated fatty acid and specific pinolenic acid reached 85.55% and 13.65%, respectively. The antioxidant activity and physicochemical properties of P.koraiensis seed oil were also determined. The seed oil exhibited better DPPH radical scavenging activity with the IC50 value of 0.0954 g·mL-1. And the seed oil was a high quality natural oil with lower acid value, lower peroxide value and high iodine value.

Key words: Pinus koraiensis Sieb seed oil, ultra turrax-microwave assisted extraction, unsaturated fatty acid, quality evaluation
