Abstract Many oil-encapsulation techniques, in which particles are used to improve the stability of polyunsaturated fatty acids (PUFAs) against oxidation and the handling of oils, have been reported. We developed techniques for encapsulating oil within powders with a liquid–liquid interfacial crystallization by using nozzleless electrostatic atomization. This process was used to prepare fine spherical encapsulated soybean oil particles with a microscale single process. An inexpensive soybean oil containing PUFAs was chosen as the oil phase. W/O emulsion systems were synthesized via the electrostatic atomization process. After the W/O emulsions were prepared, glycine and taurine well provided in supplements were used as the wall material for encapsulation. The soybean oil content of the encapsulated particles and their stability at high temperatures were evaluated. The oxidative stability of the soybean oil during high-temperature storage was improved for the encapsulation.

无喷嘴静电雾化在固体物质包封豆油中的应用

摘要 已经报道了许多油包封技术，其中使用颗粒来提高多不饱和脂肪酸 (PUFA) 对氧化和油处理的稳定性。我们开发了通过使用无喷嘴静电雾化将油包裹在具有液-液界面结晶的粉末中的技术。该工艺用于通过微型单一工艺制备精细球形包封大豆油颗粒。选择含有 PUFA 的廉价大豆油作为油相。W/O 乳液体系是通过静电雾化过程合成的。制备 W/O 乳剂后，补充剂中提供的甘氨酸和牛磺酸被用作包封的壁材料。评估了包封颗粒的大豆油含量及其在高温下的稳定性。大豆油在高温储存过程中的氧化稳定性通过包封得到改善。
