摘要: 榛仁油中不饱和脂肪酸含量高达95.2%,极易氧化变质,且与食品原料不易混合均匀。本研究采用微胶囊化技术,将液态的榛仁油制成固体粉末油脂。试验结果表明,喷雾干燥工艺参数为:均质次数为3次、均质压力为40MPa、进料温度40~50℃、进风温度180℃、出风温度90℃,在此工艺条件下微胶囊化榛仁油的效率可达到87%以上。制取的粉末榛仁油微胶囊为乳白色粉末,水分含量2.53%,密度0.71g/cm3,溶解度97.1%,平均粒度16.7μm。

Abstract: The content of unsaturared fatty acid in hazelnut oil is approximately 95.2%. It is easy to be oxidated and be spoil. The microencapsulated technology was adopt to make the liquid hazelnut oil into solid powder in this study. The results indicated that the optimum parameters about microencapsulated hazelnut oil techniques were as that: the frequency of homogenizing was 3, homogenizing pressure was 40MPa, feed temperature was about 40℃ to 50℃, temperatures of inlet wind and outlet wind were 180℃ and 90℃, respectively. The microencapsulating efficiency of hazelnut oil was about 87% on the condition above. The preparation of hazelnut oil showed milkiness in colour, and the content of moisture, the density and solubility were about 2.53%, 0.71g/cm3 and 97.1%, respectively.
