Abstract

OCR 09WP 23 / 06 / 2569 Nanoparticles encapsulate key substances from riceberry extract using nanotrans-ethosome technology. The manufacturing process for these particles involves a mixture of ingredients including riceberry extract, plant-based fats, and other fats. Animals; surfactants such as sorbitan esters and polysorbates. The developed transethosome nanoparticles exhibit good stability and homogeneous dispersion in water. No separation occurs when left at room temperature. The particles have good dispersion, are of similar size throughout the system, and... Furthermore, with particle sizes smaller than 200 nanometers, it was found that the developed technology can increase absorption. The active compounds from riceberry extract are absorbed more effectively in the digestive system than those prepared in solution form. The key compounds from the riceberry extract, encapsulated in trans-ethosome nanoparticles, have antioxidant properties.
