Membrane Purification of Palm Sap (NEERA)

Palm sap is a nutritious drink, but it cannot be stored for long duration (once it is extracted from the palm tree) even under refrigeration.

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). This can be achieved without loss of nutrients, and without any use of chemical additives/ biopreservatives. The purified palm sap has a shelf life of up to 6 months.
