The invention relates to a pine nut oil rich in pinenic acid lutein ester and a preparation method thereof, belonging to the field of oil processing and food chemistry. First, lutein and solvent are added to the esterification kettle, heating, stirring to keep the temperature for 0.5 to 3 hours, cooling to less than 60 degrees C, and getting the mixture. Secondly, the ppine wool oil is added to the mixture, and the immobilized specific lipase is added at the same time, and the reaction should be kept at 30 to 60 C at normal pressure, and the heating is stopped to the normal temperature, and the reaction is finished. The reaction is finished. The reaction is finished and the reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished and the reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished and the reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished and the reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished. The reaction is finished, the reaction is finished. After the mixture was obtained, the mixture was washed, stratified and dried to remove the solvent after cooling, and then the lipase and the unreacted lutein were removed by freezing and filtering to get the pine oil rich in the lutein ester rich in Pico convergent lutein. The beneficial effects are: esterification deacidification reduces acid value of pine nut oil, reduces oil refining loss, forms pinocarfate lutein ester, gives lutein an effective component with pinocarboxate, low reaction temperature, no damage to high unsaturated fatty acid and lutein, simple operation and easy to industrial production.

一种富含皮诺敛酸叶黄素酯的松子油及其制备方法
本专利技术属于油脂加工与食品化学领域,涉及一种富含皮诺敛酸叶黄素酯的松子油及其制备方法,具体涉及松子油中的游离脂肪酸与叶黄素通过固定化酶催化酯化反应制备皮诺敛酸叶黄素酯功能油脂的方法。
技术介绍
皮诺敛酸(Pinolenicacid)为全顺式5,9,12十八碳三烯酸,它与地球上所有植物当中的不饱和脂肪酸不同,它只存在于松籽油中,不仅能够降低胆固醇(TC)、甘油三酯(TG),升高高密度脂蛋白(HDL),而且还能抑制、消除其他不饱和脂肪酸对机体的不利影响。同时,目前最新研究表明,它还具有抗炎、解热、镇痛,对抗各种真菌、病毒感染,促进中老年人排泄功能等作用。它被专家誉为洗血因子。成熟松子需多年生长,因此,松子脂肪中游离脂肪酸含量较高,一般松子脂肪中酸值为30-60KOHmg/g,松子油在精炼过程中,需要大量的NaOH来中和去除游离脂肪酸,且产生大量皂脚,使得产品得率偏低,造成了油脂浪费,限制了工业化生产。叶黄素酯2008年卫生部批准为新资源食品,叶黄素分子中存在共轭双键,共轭双键特别容易氧化,叶黄素的不稳定性限制了叶黄素的开 ...
