The β-glucan has been useful used in medicine, pharmacy, cosmetic and food industries as bioactive polymer. Unfortunately, high molecular weight, high viscosity and low solubility limit its applications. The β-glucan of high molecular weight was depolymerized using high pressure homogenizer (Nano Disperser, ILSHIN AUTOCLAVE) of micro orifice module type. 5 % (w/v) β-Glucan solution was prepared with 1 % (w/v) sodium hydroxide solution. The β-glucan solutions were treated through a high pressure homogenizer at 500, 1000 and 1500 bar for 1 to 5 cycles. The pressure and the number of pass increases make viscosity and molecular weight decrease without any additive such as strong acid/alkali solution. Therefore, high pressure homogenizer process could be used in commercial processes as an effective method to resolve the physical problems involved in the use of β-glucan with high viscosity and low solubility. The depolymerized β-glucan was characterized by viscometer, GPC, FT-IR, UV-Vis and XRD. |
