摘要
用超高压处理毛梾籽,使用气质联用的方法检测了不同压力对毛梾籽油成分的影响。不同压力检测出来的脂肪酸有棕榈油酸、棕榈酸、亚油酸、油酸、反异油酸、木质素酸、三十烷酸、硬脂酸。棕榈油酸在400 MPa时达到最低值,相对含量为4.948%,棕榈酸在150 MPa时达到最高值,相对含量为48.49%,油酸300 MPa时达到最高值,相对含量为31.55%。反异油酸常压时相对含量最高,为19.43%。亚油酸常压时相对含量最低,为11.6%,在200 MPa时达到最高值,20.94%。
In this paper, cornus wateri seeds were pressed with ultra-high pressure.The effects of different pressure on the composition of cornus wateri seeds oil were detected by GC-MS. In different pressure, detected palm oleic acid, palmitic acid, linoleic acid, oleic acid, trans-vaccenic acid, lignin acid, 30 alkanes acid, stearic acid. Palm oleic acid relative content reached the lowest with 4.948% in 400 MPa. Palmitic acid reached the highest value at 150 MPa, with a relative content of 48.49%. Oleic acid relative content reached the highest with 31.55% in 300 MPa. The relative contents of trans-vaccenic acid as high as 19.43% in the atmospheric pressure. The linoleic acid relative content is 11.6%, it is the lowest under atmospheric pressure, it peaked in 200 MPa with 20.94%.
