Abstract
Multilayer microcapsules are micro-sized capsules composed of several layers. Multilayer microcascules can be made from Soy Protein Isolate (SPI) nanofibrils using the Layer by Layer (LbL) method. The thickness of the microcapsule layer is one of the physical characteristics that need to be studied for the application of multilayer microcapsules in the fields of health, food, industry and agriculture. The thickness of the microcapsule layer can be determined based on the diameter of the microcapsule layer. This study examines the thickness of each layer of multilayer microcapsule made from SPI nanofibrils. The diameter of the microcapsules can be measured using a zetasizer. The measurement results of the microcapsule layer diameter showed that the diameter of the second, fifth, and seventh layers were 9,703 nm, 12,450 nm, and 12,890 nm, respectively. The equation of the microcapsule layer diameter to the number of microcapsule layers was y = 658.73x + 8,603.9 with the value of R2 = 0.92. The average thickness of the microcapsule layer is 604.45 nm.
