摘要:
光皮树是一种高产的木本油料树种,其树油的不饱和脂肪酸含量高,具有很高的应用价值。利用微胶囊技术制备微胶囊粉末光皮树油,研究了不同质量配比的硬脂酰乳酸钙和甜菜碱复配乳化剂对光皮树油微胶囊化效率和载油量的影响,确定了喷雾干燥技术制备微胶囊粉末光皮树油产品的工艺条件。结果表明:当硬脂酰乳酸钙/甜菜碱质量比为2/3时复配乳化剂乳化光皮树油形成的乳液不分层,具有较好的乳化稳定性,粒径大小为16.37 μm,且喷雾干燥制备的微胶囊粉末光皮树油产品颗粒均匀、细腻、干燥。经扫描电镜观察,以该乳化剂质量比例制备的微胶囊粉末光皮树油颗粒外形较圆整, 大小分布较均匀, 表面光滑,含水量为4.28%,对光皮树油具有较好的包埋效果,其包埋率及载油量分别为91.2%和28.0%,硬脂酰乳酸钙/甜菜碱(质量比为2/3)这一复配组合的乳化剂是制备高包埋率及高载油量微胶囊粉末光皮树油的理想乳化剂。制备的微胶囊可同时补能和补钙,对于提高微胶囊油脂粉品质具有极为重要的意义。
Abstract:
As Swida wilsoniana oil has a high content(about 72%)of unsaturated fatty acids(oleic acid, 29.83%; linoleic acid, 39.15%; linolenic acid, 2.59%), microcapsule powder of S.wilsoniana oil was prepared by microcapsule technology to prevent oxidation and extend shelf life in this study.The aim of this work was to produce microencapsulated S.wilsoniana oil using spray drying and to investigate the influences of different ratios of calcium stearoyl lactylate and betaine as compound emulsifier on the microencapsulation efficiency and oil loading of microencapsulated S.wilsoniana oil.The process conditions of spray drying technology to prepare microencapsulated S.wilsoniana oil with high-quality product were studied and determined.The results showed that a stable emulsion was obtained using the compound emulsifier of calcium stearoyl lactylate/ betaine at a ratio of 2/3(m/m)to emulsify S.wilsoniana oil, and the emulsion did not stratify with the particle size of 16.37 μm.The microcapsule powder prepared by spray drying using the compound emulsifier of calcium stearoyl lactylate/ betaine at a ratio of 2/3(m/m)was uniform, fine and dry.Moreover, the scanning electron microscopy images showed that the microencapsulated S.wilsoniana oil emulsified by calcium stearoyl lactylate/ betaine(2/3, m/m)had a nearly spherical shape, uniform size distribution and smooth surface smooth surfaces, and with the moisture content of 4.28%, which had a good encapsulation effect on S.wilsoniana oil.However, the microcapsule powder prepared by the calcium stearoyl lactylate only as emulsifier emulsify S.wilsoniana oil was agglomerated, which could be caused by the high surface oil content.By using the compound emulsifier of calcium stearoyl lactylate/betaine at a ratio of 2/3(m/m), the encapsulation efficiency reached 91.2%, oil loadings were achieved up to 28.0%.These results indicated that the combination of calcium stearoyl lactylate/betaine at a ratio of 2/3(m/m)was an ideal emulsifier for the preparation of high microencapsulation efficiency and payload for microcapsules of S.wilsoniana oil.The prepared microcapsules can offer supplement and calcium simultaneously, which is of great significance for improving the quality of microcapsule oil powder.
