Abstract
Beta-glucan (β-glucan) is a macromolecule structure where glucose unit has bonded through β-glycosidic bond at 1 and 3 positions. It is well known as a natural immunomodulator without exhibiting any side effects via enhancing immunity. Mushroom contains a large amount of β-glucan and it has anticancerous and antioxidant efficacy. Structure and physical properties of β-glucan are highly influenced by the types of mushroom. In particular, Grifola frondosa has β-1, 3 and β-1, 6 bonds in their structure. It has been noted that β-glucan content also depends upon the size of mushroom particles. The exact content of β-glucan and their immunological activity by a particle size of G. frondosa have yet to be fully elucidated. Herein, β-glucan contents were analyzed according to the particle size of leaf mushroom followed by cell activation and immunoactivity analysis. The highest β-glucan content was observed at a particle size of 20-30 μm (27.65 ± 0.30 w/w). All samples showed ~ 103% cell activation compared to the control and greater cell activity was observed at higher concentration. The significant increase in cytokines secretion was observed in the presence of 20-30 μm particle size of G. frondosa compared to the control. This study suggested that 20-30 μm size is the suitable size of G. frondosa that can be used as a health supplement and food additive to act as an immune booster, hypotensive agent, and hypoglycemic agent.

( The role of glucan in stimulation of immune reactions has been studied for several decades... Short-term oral application of natural immunomodulating glucans from Maitake and Shiitake mushrooms strongly stimulated both the cellular and humoral branch of immune reactions. These activities were significantly higher than those of AHCC. )
