The characterization and physicochemical properties of crude powder (D50 120.45 mm), fine powder (D50 65.86 mm), ultrafine powder I, ultrafine powder II, and ultrafine powder III were compared by colorimetric determination, particle size measurement, electron microscopy analysis and infrared spectroscopy. The powder processing characteristics, fluidity of the powder, and the changes of the content of polysaccharides and saponins were studied. With the decrease of powder particle size, the solubility, wettability and fluidity of the powder increased, and the swelling degree and water holding capacity decreased. The content of tea polysaccharides and saponins in the ultrafine powder was also significantly higher than that of powder. The length of ultrafine pulverization, the content of tea polysaccharide gradually increased, and the saponin content was different. The characteristics of different particle size the powders of M. peltatus were different. Ultrafine powder has higher dissolution rate, tea polysaccharide, saponin content, so it is more easily absorbed by the human body. With high bioavailability and easy processing, ultrafine powder of M. peltatus has a better development prospect.

Key words: Mallotus peltatus, superfine pulverization, physicochemical properties, tea polysaccharide content, saponin content
