Dissolution rate , periduium state, nutrient component and fatty acid composition of 5 species of natural pollen and 3 species of processed pollen were carried out for evaluation of quality. Natural pollens had average 11.5% of moistures, and had native peridium may be responsible for allergy. The average dissolution rate of natural pollens were low as 66.3%. One among 3 species of processed pollen was observed to have not peridium, resulted in higher dissolution rate. Major fatty acid of pollen was palmitic acid but content of oleic acid was lower than that of other plant seeds.
