| Title | Membrane purification of Palm Sap (Neera) |
| Knowhow is available for | A process for enhancement of shelf life of palm sap by using polymeric membranes to remove microbes and impurities |
| Summary | Polymeric membranes are used to purify/clarify palm sap (Neera).
-The resulting palm sap is visibly better, without turbidity, is free of bacteria and yeast (that cause fermentation)
-Can be achieved without loss of nutrients, and without any use of chemical additives/bio-preservatives.
-The purified palm sap has a shelf life of up to 6 months
