叶黄素油悬液的制备工艺研究

Process research on the preparation of lutein oil suspension

对乳化法制备叶黄素油悬液的配方组成及制备工艺进行研究.选择乳化剂种类、乳化剂用量、乳化温度、乳化时间和乳化转速为参数,以叶黄素油悬浮液稳定系数R值为稳定性评价指标,优化叶黄素油悬液的制备工艺.结果表明:以卵磷脂和单硬脂酸甘油脂(质量比1∶1)复配作为乳化剂、乳化剂添加量4%(质量百分比)、乳化温度65℃、乳化转速16 000 r.min-1和乳化时间30 min时制备的产品稳定性最佳,静置6个月未发现析油分层的现象,并且色泽无明显变化.

The formulation and emulsification technology of lutein oil suspension were studied to in- crease the stability and bioavailability of lutein dispersions in oil. The optimum process conditions, in- cluding the concentration of emulsifier, emulsifying temperature, emulsifying time and velocity for lu- tein dispersions in oil were optimized by orthogonal design, taking the stability coefficient R value of the product as an indicator. Results showed that the optimal conditions were as follows： 4% （w/w） e- mulsifier （ combination of 2% （w/w） lecithin and 2% （w/w） glycerol monostearate）, emulsifying tem- perature at 65℃, emulsifying speed at 16000 r · min^-1 , emulsifying time for 30 min. There is no ob- vious oil separation on the top and no color change of the product after 6 months.
