Maintaining adequate moisture levels in the bleacher throughout the bleaching process affords better removal of soaps, phospholipids and chlorophyll due to bleaching clay's affinity for these compounds. More specifically, phospholipids and soaps are more readily removed from fats and oils when properly hydrated.

The results are shown in Fig. 3. An addition of 2% (w/w) of NH 4 NO 3 in potato waste was found to be the optimum concentration, as it significantly enhanced the phytase production (11.53 ± 1.11 U/g ds). The phytase production was decreased when NH 4 NO 3 concentration was greater than 2% w/w.
