The sizes of the coconut proteins therefore may be smaller than,
the same or even larger than that of the UF membrane pores
(10 kDa and 20 kDa)
Moreover, there are some micro-nutrients
in the SCM such as vitamins, nitrogenous compounds, organic
acids and so forth. For instance, vitamin B12 (molecular size,
2.4 nm), phytohormones (molecular size, 0.05–0.4 lm) and other
low molecular weight biologically active compounds (e.g. pyridoxine
1 nm)
