Abstract

The encapsulation of Mango (Mangifera indica Linn.) cultivar Chok-Anan seed kernel, which were collected as waste from the fruit industry in Thailand, was investigated to compare the use of methyl gallate as a bioactive substance. Ethanolic extracts were obtained and characterized by total phenolic content and antioxidant activity, which was assessed with 2.2-diphenyl-2-picrylhydrazyl radical. Mango seed kernel (MSK) lyophilized extracts were encapsulated using the water-in-oil-in-water (W1/O/W2) emulsion system before spray drying. The electron microscopy (SEM) was determined after formulation of each type of complex, droplet sizing, solubility, the bioactive compounds microencapsulated yield (BMY) and scanning. The MSK extract showed significantly (P<0.05) higher antioxidant capacity than that of α-tocopherol. Overall, the average size in terms of d32 values of W/O/W emulsions was 2.20 +± 0.10 μ μm. The encapsulated samples showed higher solubility in oil than water compared to MSK extract and methyl gallate. The MSK extract and methyl gallate encapsulation yields reached values above 98% and 92%, respectively. In the SEM micrographs of encapsulated MSK, the extract appeared rather rounded compared to the others. The results imply that encapsulation is a promising technique to develop MSK extract solubility in oil.
