摘要
为开发品质较好的紫海胆(Anthocidaris crassispina)黄油微胶囊,以辛烯基琥珀酸酯化淀粉(HICAP100)和β-环糊精为壁材,通过喷雾干燥制备紫海胆黄油微胶囊,以乳化液稳定性及包埋率为指标,通过单因素试验,研究紫海胆黄油微胶囊的壁材比例、乳化液浓度及油脂添加量对微胶囊的影响。以单因素试验的结果为基础,采用正交实验得出紫海胆黄油微胶囊化的最优制备工艺,并检测其理化性质和卫生指标。结果显示,最优制备工艺为:壁材比例为4∶2(HI-CAP100∶β-环糊精),乳化液质量浓度为17%,油脂添加量为15%。经过分散机乳化30 min,利用料理机均质5 min,在进风温度180℃、出风温度80℃、进样速度500 mL/h下进行喷雾干燥时,得到的包埋率和乳化液稳定性分别为95.7%和96.8%,紫海胆黄油微胶囊的水分含量为2.82%,溶解度为71.94%,自流角为22.05°,菌落总数为480 CFU/g,大肠菌群数<30 MPN/100 g,霉菌和酵母<10 CFU/g,金黄色葡萄球菌、沙门氏菌、志贺氏菌皆未检出。紫海胆黄微胶囊的理化性质及安全卫生指标皆符合行业标准。
To develop a better quality microencapsulation of Anthocidaris crassispina gonad oil,Anthocidaris crassispina gonad oil was microencapsulated with the method of spray drying by using n-octenylsuccinate-derivatized starch（HI-CAP100） and β-cyclodextrin as the principal wall materials. Using emulsion stability and embedding rate as evaluation indexes,the effects of wall material ratio,the concentration of emulsion and the addition amount of oil on the microcapsules were studied through single factor experiments. Based on single factor experiments,orthogonal method was used to optimize the process conditions,and the physicochemical properties and hygiene indicators were detected. The results showed that, the optimum conditions of Anthocidaris crassispina gonad oil micro-encapsulation were：the ratio of HI-CAP100 and β-cyclodextrin was 4∶ 2,the concentration of emulsion 17%,and the addition amount of oil 15%;after being emulsified with IKA homogenizer for 30 min and homogenizing with a cooking machine for 5 min,the inlet air temperature of spray dryer 180 ℃, outlet air temperature 80 ℃, and the sampling rate of 500 mL / h, under which, 95. 7% of embedding rate and 96. 8% of emulsion stability were obtained. The moisture content in the Anthocidaris crassispina gonad oil microcapsule was 2. 82%, the solubility was 71. 94%, the angle of auto-flowing was 22. 05°,the total number of colonies was 480 CFU/ g,the number of coliforms was less than 30 MPN/ 100 g,mold and yeast were less than 10 CFU/ g,Salmonella,Shigella and Staphylococcus aureus were not detected.The physicochemical properties and safety and hygiene indicators of Anthocidaris crassispina gonad oil microcapsules are all in line with the industry standards.
