摘要
本研究通过对叶黄素加工过程中阶段产物的典型多环芳烃和塑化剂含量跟踪检测,明确了叶黄素提取过程中典型多环芳烃苯并(α)芘(benzopyrene,BaP)、苯并[b]荧蒽(Benzo[b]fluorathene,B[b]F)、苯并[a]蒽(Benz(a)anthracene,BaA)、屈(Chrysene,CHR)以及塑化剂邻苯二甲酸二丁酯(dibutyl phthalate,DBP)与邻苯二甲酸二(2-乙基己基)酯(di-2-ethylhexyl phthalate,DEHP)的迁移量和迁移规律,以期对其在叶黄素提取过程中的风险防范与控制提供参考。结果表明:以万寿菊鲜花生产叶黄素浸膏过程中,万寿菊鲜花经发酵除水制成菊花颗粒,在此阶段万寿菊鲜花中典型多环芳烃和塑化剂全部迁移至菊花颗粒;菊花颗粒经溶剂提取生产叶黄素浸膏过程中四种多环芳烃的平均迁移率为40%,塑化剂DBP和DEHP的平均迁移率分别为44.78%和40.49%,从菊花颗粒迁移至叶黄素浸膏的典型多环芳烃和塑化剂总量少于渣子,但浸膏中典型多环芳烃和塑化剂的单位含量较高。以叶黄素浸膏生产晶体过程中,塑化剂和多环芳烃向晶体的迁移率都很低,其中大量塑化剂在皂化反应中被破坏,剩余则主要迁移至低含量叶黄素。其中,塑化剂DBP和DEHP向晶体的迁移率分别是0.32%和1.57%,DBP与DEHP向低含量叶黄素的迁移率分别是6.09%和30.31%,而皂化反应中被皂化掉的DBP在90%以上,皂化掉的DEHP约70%;而从浸膏到晶体的生产过程中,多环芳烃向晶体的总迁移率为0.27%,其中多环芳烃各个单一成分向晶体的迁移率均低于0.5%,多环芳烃各单一成分及总量向低含量叶黄素迁移率均在120%左右。
Polycyclic aromatic hydrocarbons and plasticizer were detected during Lutein manufactural processing.Migration of compounds including Benzo(alpha)pyrene benzopyrene(BaP),Benzo[b]fluoranthene(B[b]F),Benzo[a]anthracene(BaA),Chrysene(CRH)and plasticizer phthalic acid dibutyl(di-butyl phthalate(DBP),and di-2-ethylhexyl phthalate(DEHP)were studied in order to provide a reference for risk prevention and control during lutein manufacturing.The results showed:lutein was extracted from marigold flowers,and flowers need to be fermented to form chrysanthemum particles.During this stage,polycyclic aromatic hydrocarbons and plasticizer all transferred to chrysanthemum particles.In the stage of chrysanthemum particles extraction by solvent,the four polycyclic aromatic hydrocarbons mentioned above were migrated at the average rate was about 40%;plasticizer DBP and DEHP migration rate was 44.78%and 40.49%respectively.The total amount of polycyclic aromatic hydrocarbons and plasticizers migrated from chrysanthemum particles to lutein extracts was less than that of in the dregs,but unit content was higher.During stage of lutein crystallization from lutein extract,the mobility rate of plasticizers is very low,majority plasticizers are destroyed in saponification reaction,little remained in the low content lutein material.The migration rates of plasticizer DBP and DEHP in crystal lutein were 0.32%and 1.57%respectively.The migration rates of DBP and DEHP to low content lutein were 6.09%and 30.31%,respectively.In saponification reaction,more than 90%of DBP was saponified,and 70%of DEHP was saponified.During the stage of crystalization,the total migration rate of PAHs to crystal is 0.27%,and each PAHs migration rate to crystal is less than 0.5%,and migration rate of total and single PAHs to lutein is about 120%.
