摘要:

为充分利用生姜资源,以榨汁后姜渣为原料,采用正交试验方法确定超临界二氧化碳(SCF-CO2)萃取姜渣中姜渣油树脂的最佳工艺条件。结果表明:最佳工艺条件为粉碎粒度50 目、萃取压力25MPa、萃取温度45℃、萃取时间90min。姜渣油树脂在动物油中的抗氧化作用和对1,1- 二苯基-2- 苦基肼(DPPH)自由基的清除作用结果表明,SCF-CO2 萃取的姜渣油树脂具有良好的抗氧化作用。

Abstract:

In order to make full use of the ginger residues after making ginger juice, oleoresin was extracted from ginger residues by using supercritical fluid CO2 (SF-CO2) technology. The optimal extraction processing was explored by orthogonal experiments to be particle size for ginger residues of 50 mesh, extraction pressure of 25 MPa, extraction temperature of 45 ℃ and extraction time of 90 min. Meanwhile, an obvious effect of oleoresin from ginger residues on the peroxidation of lard oil and scavenging activity of DPPH free radicals was observed. Therefore, the oleoresin from ginger residues has strong antioxidant activity.

Key words: residue, SF-CO2, oleoresin, antioxidant activity, natural antioxidant
