was first treated using dilution and settlement and the unsettled layer of NRD was then processed using membrane filtration at a different range of molecular weight cut-offs (MWCO), namely micro-filtration (MWCO: 0.2 µm), ultra-filtration (MWCO: 10 kDa) and nano-filtration (MWCO: 500 Da...
After this process, fractions containing peptides with molecular weight between 10,000 Da and 3000 Da (retentate fraction) and fractions containing peptides below 3000 Da (permeate fraction) were then freeze-dried and stored at −20 ◦C until subjected to antioxidant capacity analysis. 3.5.2....
