摘要： 以漆脂为芯材，采用不同种类的壁材进行复配，并通过喷雾干燥制备漆脂基脂肪粉，以乳化能力和包埋率为指标，通过单因素试验优化了漆脂基脂肪粉的制备工艺：壁材为麦芽糊精/大豆分离蛋白（4：1，质量比，下同），乳化剂为蔗糖脂肪酸酯/单硬脂酸甘油酯（8：2），乳化剂添加量为3.5%（以芯壁总质量计，下同），阿拉伯胶添加量为2.5%，壁芯质量比为2：1，乳液含总固形物30%，在此条件下制得的乳液的乳化能力为94.2%，漆脂脂肪粉的包埋率为83.46%。红外光谱分析表明漆脂脂肪粉的包埋结构初步形成；GC-MS检测发现乳化和喷雾干燥对漆脂主要脂肪酸组成基本没有影响，漆脂脂肪粉含有68.329%的棕榈酸、19.245%的油酸和8.673%的硬脂酸；扫描电镜和粒径分析显示漆脂脂肪粉呈球形，分布较为均匀，粒径主要分布在1~5 μm；加速氧化储藏试验表明经过微囊化包埋处理30天后，漆脂的过氧化值（67.8 mmol/kg）明显高于漆脂脂肪粉（27.2 mmol/kg），说明微胶囊包埋能够有效减缓漆脂的氧化酸败。

Abstract: Using lacquer wax as core material, different kinds of wall materials were used to prepare lacquer wax fatty powder by spray drying. The emulsifying ability and entrapping rate were taken as response values. The preparation conditions of lacquer wax fatty powder were optimized by single factor experiment.The results showed that the wall material was the blend of maltodextrin and soybean protein isolate(SPI)(mass ratio 4:1);the emulsifier was sucrose fatty acid ester and glyceryl monostearate(mass ratio 8:2), and the addition amount was 3.5%(based on the total mass of core wall); the amount of arabic gum was 2.5%, the ratio of wall to core was 2:1, the total solid content was 30%. Under these conditions the emulsifying ability of emulsion was 94.2% and the embedding rate was 83.46%. Fourier transform infrared spectroscopy (FT-IR) showed that the entrapped structure of lacquer wax fatty powder was initially formed. The results of GC-MS showed the emulsification and spray drying almost no influence to the composition of main fatty acids in lacquer wax fatty powder. The lacquer wax fatty powder contained 68.329% palmitic acid, 19.245% oleic acid and 8.673% stearic acid. Scanning electron microscopy (SEM) and particle size analyzer showed that the lacquer wax fatty powder was spherical, and its particle size was mainly distributed from 1 to 5 μm. The accelerated oxidation storage test showed that the peroxide value (67.8 mmol/kg) of lacquer wax was significantly higher than that of lacquer wax fatty powder(27.2 mmol/kg) after microencapsulation, indicating that microencapsulation could effectively reduce the oxidative rancidity of lacquer wax.
