From: Preparation and performance of insect virus microcapsules
The morphology of microcapsules at different pH values with the gelatin/CMC ratio of 9:1. a pH= 4.54, b pH= 4.71, c pH= 4.76. When the ratio of gelatin/CMC was 9:1, the pH range for the formation of spherical microcapsules was 4.54 to 4.71, and its particle size decreased while lowering the pH value
