Effect of alginate concentration on the physicochemical characteristics and entrapment efficiency of bioactive compounds in microencapsulated bekasam extract

Abstract

Bekasam extract functions as an effective agent for reducing cholesterol and hypertension levels. One of the practical methods to utilize this extract is through microencapsulation. During the manufacturing of consumables, microcapsules can be incorporated into foods and beverages as functional additives. Therefore, this study aimed to investigate microencapsulation methods of bekasam extract, specifically by using ionic gelation with sodium alginate as a coating at varying concentrations of 0.50%, 0.75%, 1.00%, and 1.25%. The results showed that the diameter of the microcapsules produced ranged from 3.71-3.92 mm, and the yield was 21.83-40.47%. The microcapsules contained 6.3-10.08% peptides and 37.89-46.39 ppm of Lovastatin with an entrapment efficiency of 17.31-27.69% and 59.08-72.76%, respectively. The microcapsules made with alginate (1.25%) had higher levels of Lovastatin and peptides.
