通过水相滴定法制备蛇油纳米乳,研究了混合油相、表面活性剂、助表面活性剂对蛇油纳米乳制备的影响,并利用伪三元相图法确定最佳蛇油纳米乳配方.结果 表明:混合油相选择蛇油和肉豆蔻酸异丙酯(IPM),表面活性剂选择Span80和Tween80二者质量比27∶73,助表面活性剂选择PEG400;最佳蛇油纳米乳配方为蛇油1.6 g、IPM 2.4 g、Span801.08 g、Tween802.92 g、PEG4004.0 g、水8.0g.所制得的蛇油纳米乳为O/W型,平均粒径为63.01 nm,PDI为0.226,Zeta电位为-19 mV,液滴外观为圆形,粒径均匀且状态良好;离心后清澈透明,不分层;不耐高温,需要在25℃以下贮存;冷冻后,可以在室温下恢复到初始状态;氧化稳定性较蛇油提高.

从大豆油精炼生产工艺出发,考察γ-生育酚、磷、金属离子等影响大豆油回色的微量成分在精炼过程中的含量变化及其与辅料添加量、脱臭条件对储存期成品大豆油回色的影响.结果 表明:γ-生育酚在脱臭工段损失最大,建议脱臭温度在250℃以下,而辅料和汽提蒸汽压力的微调对其影响不大;水化磷脂基本在脱胶工段可以彻底脱除,酸炼脱胶主要脱除非水化磷脂,建议将磷含量控制的关键环节设置在脱胶工段,以降低脱色工段白土吸附除磷的压力和生产成本;金属离子基本可以在正常的脱酸、脱色工段利用皂脚和脱色剂吸附脱除;γ-生育酚损失率、脱臭油的磷

以油茶籽油为基料油,巴西棕榈蜡为凝胶剂制备巴西棕榈蜡-油茶籽油凝胶,探讨不同蜡添加量对其外观形态、持油率、硬度、晶型、热力学性质、氧化稳定性以及消化特性的影响.结果 表明:蜡添加量为5％时才能使油茶籽油凝胶化,凝胶的硬度、持油率以及结晶/熔融峰值温度总体随着蜡添加量的增加而增大;凝胶的网络结构能够抑制油茶籽油次级氧化产物生成,提高油茶籽油的氧化稳定性;蜡添加量越高的凝胶脂肪酸释放率越低.
