Abstract

India is the largest producer of coconut. The neera is a very susceptible product tapped from the spadix of coconut. Shelf life of the neera is very low because of bacteria and yeast fermentation. Novel processing method are emerging techniques to increase the shelf life of the product. Is study is focusing of the optimizing the ohmic processing by using response surface methodology. Process temperature (60 to 90 °C), process time (60 to 300 s) and process voltage (10 to 40 V) for ohmic heating of neera. The pH and overall acceptability were fixed as a response. The desirable pH and overall acceptability were attained in voltage 23 V, time 196 s and temperature 62o C of ohmic processing.

Keywords

Novel processing of neera. Coconut sap, shelf life extension

Conclusion

According to obtained results from the surface response method, values of Lack of fit were not significant for any factor of pH and overall acceptability. Value of R2 was greater than 0.73. The voltage 23V, time 196s and temperature 62oC was gave maximum overall acceptability and neutral pH during ohmic processing.
