Abstract:This study aims to explore the influence of cell wall disruption on nutrients and physicochemical properties of pine pollen.To be specific，the nutrients，water-holding capacity，oil-holding capacity，cation exchange capacity，cholesterol-adsorbing capacity，nitrite-scavenging capacity，and metal ion-adsorbing capacity of raw pine pollen and pine pollen with cell wall disrupted were measured and analyzed.The results showed that the content of crude fat and total soluble sugar content of pine pollen were significantly increased after cell wall disruption.In addition，the content of total flavonoids，total phenols，and total triterpenes was 18.6%，30.2%，and 29.6% higher than that in the pollen without cell wall disruption，respectively.Cell wall disruption enhanced the water-holding capacity，oil-holding capacity，cation exchange capacity，and nitrite-scavenging capacity of pine pollen，but had no significant influence on the cholesterol-adsorbing capacity of the pine pollen.The pine pollen with cell wall disrupted showed stronger adsorption of Cu2+but weaker adsorption Cd2+and Pb2+than the raw pine pollen.In summary，the levels of main nutrients and functional components of pine pollen were increased and most of the physicochemical properties were markedly improved after cell wall disruption.
