Fresh Rohdea fruits contain proteases with high hydrolytic activity towards casein, and proteases are currently one of the three major enzyme preparations used in industry, one of the most used enzymes in industrial species, accounting for about 60% of the total enzyme, and under the same conditions, the protease activity of fresh Rohdea fruits is more than 10 times the activity of papain enzymes, which has high exploitation and utilization value.
For the separation of S. rosenbergii using ultrafiltration membrane, a suitable ultrafiltration membrane with a suitable molecular mass cut-off must be available to achieve the desired separation.The test results showed that the high rejection of ultrafiltration membranes with relative molecular mass cutoffs of 10000 and 25000 resulted in the low yield of Rhubarb;Ultrafiltration membranes with a relative molecular mass cut-off of 80000 pass through high and low contents;Ultrafiltration membranes with a relative molecular mass cutoff of 40000 achieved the requirements in both content and yield, playing a good separation effect.So the ultrafiltration membrane with the relative molecular mass cutoff of 40000 was chosen to perform the separation.
Most of UF membranes are used in the fields of separation, concentration, bacteria removal and heat removal of materials.
