Vitamin A, also known as retinol, is a fat-soluble vitamin that plays crucial role in various physiological functions In vivo. However, factors such as light, oxygen, and others may impact the stability of V. To enhance its stability. This study microencapsulated V, Gelatin, carboxymethyl cellulose, and salt were mixed in a ratio of 5:1:0.1 as the shell material. Additionally, 12% TG and 3.5% sucrose ester were added with core-shell ratio of 1:8. The experimental results indicated that V microcapsules exhibited an encapsulation efficiency of 81.12%, after 9 weeks of storage this rate decreased to 75.38%, and the encapsulated V oil did not exhibit extravasation. The addition of an appropriate amount of salt to the shell material enhanced the mechanical properties of the shell material, compared to the shell material without added salt, the leakage of V in the salt-added sample decreased by 5.8% for 30 min and 14.5% for 60 min. In vitro release experiments showed that after 3 h of incubation in simulated gastric fluid, the microcapsules had an 18.52% release rate. In simulated intestinal fluid, this increased to 66.58%, indicating strong enteric solubility.

维生素A,也称为视黄醇,是一种脂溶性维生素,在体内的各种生理功能中起着关键作用。然而,光、氧等因素可能会影响维生素A的稳定性。为提高其稳定性,本研究将维生素A微囊化,以明胶、羧甲基纤维素和盐按5:1:0.1的比例混合作为壳材。此外,添加12%的甘油和3.5%的蔗糖酯,核壳比为1:8。实验结果表明,维生素A微囊的包封率为81.12%,储存9周后该比率降至75.38%,且包封的维生素A油未出现渗漏。向壳材中添加适量的盐增强了壳材的机械性能,与未添加盐的壳材相比,添加盐的样品中维生素A在30分钟时的渗漏率降低了5.8%,60分钟时降低了14.5%。体外释放实验表明,在模拟胃液中孵育3小时后,微囊的释放率为18.52%。在模拟肠液中,这一比例增加到66.58%,表明具有较强的肠溶溶解性。
