The Difference

Beta glucan is a polysaccharide compound, generally not soluble inwater and resistant to acid. Beta glucan is used as an immunomodulator (enhancing the immune system) in mammals is usually a beta-glucan soluble in water, easily absorbed and has a low molecular weight. Several example of beta-glucan such as cellulose (β-1 ,4-glucan), lentinan (β-1 0.6-glucan) and (β-1 ,3-glucan), pleuran (β-1, 6 and β-1 ,3-glucan) are isolated from species of fungi Basidiomycota include mushrooms (Pleurotus ostreatus) and shiitake (Lentinus edodes).The purpose of thisresearch activity is to obtain beta-glucan compound that can be dissolved in water and in alkali derived from fungi Basidiomycota, i.e, Oyster mushrooms (Pleurotus ostreatus) and shiitake (Lentinus edodes). The result of beta-glucan compared to characterize the resulting beta glucan that is molecular structure . The difference of beta glucan extraction is based on the differences in solubility of beta-glucan. Beta glucan could be water soluble and insoluble water.

Continuous Preparation

The continuous production of water-soluble low-molecular-weight chitosan (WSLMWC) was successfully achieved with an innovative continuous production system which consisted of ozone generating subsystem, degradation subsystem, and fractionation subsystem. The continuous production of the WSLMWC was performed through three uninterrupted steps: the first, the continuous preparation of the ozone from compressed oxygen, the second, the continuous degradation of chitosan by ozone treatment, and the last, the continuous fractionation of the WSLMWC from the degraded chitosan solution (DCS) by ultrafiltration (UF) membrane. The DCS as the most suitable feed supplied to UF membrane was ascertained. Three different WSLMWC products as useful materials in biomedicine and food were obtained, namely LMWC-3KDa, LMWC-5KDa, and LMWC-10KDa.
