Abstract:

Grape skin was processed into ultrafine powder. The average particle size of grape skin ultrafine powder was determined as 7.8μm and the broken rate of cell wall was calculated as 100%. Several characteristic indexes of the grape skin ultrafine powder and common powders with different particle sizes were compared. The results showed that the smaller grape skin powder particle size, the higher the fluidity, the solubility, the distribution and dissolution of polyphenols. Therefore, the nutritional components in grape skin ultrafine powder can be better absorbed by human body.

Key words: grape skin, ultrafine powder, characteristics
