为探究疏水性壳聚糖衍生物的应用,丰富微胶囊壁材的选择,选取壳聚糖硬脂酸钠为壁材,鱼油为芯材,采用单凝聚法制备鱼油微胶囊,通过单因素实验和正交实验对制备条件进行了优化,同时采用红外光谱、X-射线衍射光谱、扫描电镜和热重分析仪对鱼油微胶囊的结构、形貌和热稳定性进行了表征.结果 表明:适宜的鱼油微胶囊制备条件为壁芯质量比1∶1、乳化剂吐温-20质量浓度14.40g/L(芯材质量1 g时,加入乳化剂溶液200 mL)、超声功率720 W,此条件下鱼油包埋率为(50.00 ±0.47)％;所制备的鱼油微胶囊粒径分布均匀,热稳定性较好,存放18个月后,热稳定性几乎无变化.疏水性壳聚糖硬脂酸钠壁材制备简便,通过单凝聚法成囊后,能有效保持微胶囊热稳定性.

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.
