Fresh coconut sap (neera), if kept at room temperature for a couple of hours, undergoes fermentation. Fresh sap is golden in colour, with pH > 7 and has no foul odour. The traditional way of tapping, i.e. collecting the sap in a mud pot kept at the top of the palm under atmospheric temperature for 8-12 h, ferments the sap before collection itself. The colour turns whitish, pH drops to below 6 and odour of toddy (fermented smell) slowly develops. Hence the only way to avoid fermentation of sap is either keeping collection boxes at low temperature or to collect the sap every hour and store chilled. Central Plantation Crops Research Institute has developed 'coco-sap chiller' with ice cubes inside, which maintains the temperature at 2-3°C for 10-12 h, and also keeps the sap fresh and unfermented. The sap collected is sweet, non-alcoholic and also free from contaminants like ants, other insects, pollen, dust, etc. The fresh, hygienic and unfermented sap is called Kalparasa. It can be sold as a ready-to-serve health drink under refrigerated condition or can be processed into value-added natural products like sugar, jaggery, honey, syrup, etc. without the addition of chemicals.

Abstract


Fresh coconut sap (neera), if kept at room temperature for a couple of hours, undergoes fermentation. Fresh sap is golden in colour, with pH > 7 and has no foul odour. The traditional way of tapping, i.e. collecting the sap in a mud pot kept at the top of the palm under atmospheric temperature for 8-12 h, ferments the sap before collection itself. The colour turns whitish, pH drops to below 6 and odour of toddy (fermented smell) slowly develops. Hence the only way to avoid fermentation of sap is either keeping collection boxes at low temperature or to collect the sap every hour and store chilled. Central Plantation Crops Research Institute has developed 'coco-sap chiller' with ice cubes inside, which maintains the temperature at 2-3°C for 10-12 h, and also keeps the sap fresh and unfermented. The sap collected is sweet, non-alcoholic and also free from contaminants like ants, other insects, pollen, dust, etc. The fresh, hygienic and unfermented sap is called Kalparasa. It can be sold as a ready-to-serve health drink under refrigerated condition or can be processed into value-added natural products like sugar, jaggery, honey, syrup, etc. without the addition of chemicals.
