微波预处理火麻籽对其毛油δ~9-四氢大麻酚含量及品质的影响

Effect of microwave pretreatment of hemp seed on tetrahydrocannabinol content and quality of hemp seed oil

在火麻籽油的提取过程中,火麻籽中的毒性成分δ~9-四氢大麻酚易随油脂溶出,降低火麻籽油的品质。采用滚筒式微波翻炒设备对火麻籽进行热处理,旨在降低火麻籽油中的δ~9-四氢大麻酚含量,并对微波处理前后的火麻籽饼残油率及火麻籽毛油品质进行了分析。结果表明:在微波功率1 000 W、微波时间15 min的条件下,火麻籽毛油中的δ~9-四氢大麻酚含量由122.63 mg/kg降至57.33 mg/kg,氧化诱导时间由2.28 h升至3.02 h,生育酚含量由708.38 mg/kg升至716.88mg/kg,火麻籽饼残油率由14.36%降至9.98%。火麻籽毛油的酸值和过氧化值略有增加,脂肪酸组成及含量无显著变化。

Tetrahydrocannabinol is a kind of psycho active compound in hemp seed and it is easily dissolved in hemp seed oil during extraction so that the oil quality reduced. In order to reduce tetrahydrocannabinol content,hemp seeds were pretreated using tumble microwave equipment. The residual oil rates of hemp seed cake and the qualities of crude hemp seed oil before and after microwave pretreatment were analyzed. The results showed that under the conditions of microwave time 15 min and microwave power 1 000 W,the tetrahydrocannabinol content in crude hemp seed oil decreased from 122. 63 mg/kg to 57. 33 mg/kg,oxidation induction time increased from 2. 28 h to 3. 02 h,tocopherol content increased from 708. 38 mg/kg to 716. 88 mg/kg,and residual oil rate of hemp seed cake decreased from 14. 36% to 9. 98%,respectively. The acid value and peroxide value of crude hemp seed oil increased slightly and the fatty acid composition and content had no significant change.
