摘要

摘要: 以低粘度辛烯基琥珀酸淀粉酯为壁材,采用喷雾干燥法和冷冻干燥法制备紫苏油微胶囊。通过对固形物含量、芯壁比、均质时间、均质速度及乳化温度的研究,确定了最佳的制备工艺条件为:固形物含量30%,芯壁比1∶4(m/m),在50℃的乳化温度下以16000r/min的速度均质2min。比较研究了两种包埋方法对微胶囊化产品的包埋率、贮藏稳定性、感官及表面形态的影响。喷雾干燥法制备的紫苏油微胶囊化效率(MEE)可达98.86%,而冷冻干燥可达76.24%。喷雾干燥粉呈较规则的球形,流动性好,质地细腻,易溶解;表面光滑,结构致密,减少了与外界环境接触的机会,减慢了氧化速度,能有效延长贮藏期。冷冻干燥粉则疏松多孔,呈现不规则的块状,流动性差,水分含量高。结果表明,喷雾干燥法制备的紫苏油微胶囊的性能优于冷冻干燥法制备的微胶囊产品,且辛烯基琥珀酸淀粉酯通过喷雾干燥包埋紫苏油对延长贮藏期是可行的。

Abstract: The microcapsule of perilla oil was prepared by spray-drying and freeze-drying technology by using the starch octenylsuccinate as the wall material. The best technological conditions were achieved by carrying out the research on solid content, the mass ratio of core material and wall material, homogenization time, homogenization rate and emulsification temperature. The optimization preparation conditions were as follows: solid content 30 %, the mass ratio of core material and wall material 1 ∶ 4, homogenization time 2min, homogenization rate 16000r/min and emulsification temperature 50℃. The effects of microencapsulation methods on encapsulation efficiency, storage stability, sensory evaluation, and the configuration of surface were studied comparatively. The microcapsules encapsulation efficiency (MEE) of perilla oil could reach at 98.86% by spray-drying preparation and reach at 76.24% by freeze-drying preparation. Spray-dried microcapsules appeared regular spherical, good fluidity, fine texture, easy to dissolve. Smooth surface and dense structure so as to reduce the chance of contact with the outside world, slow down the oxidation rate, prolong storage period. However, freeze-dried microcapsules were porous, showing irregular lumps, poor mobility and high moisture content. It was concluded that the properties of powdered oil produced by spray-drying preceded those produced by freeze-drying, and the starch octenylsuccinate was suitable for preparation of spray-drying microencapsulated perilla oil with respect to long-term storage.
