Standardization of Process Variables for the Development of Osmo-dehydrated Coconut Haustorium.

Background: Coconut (Cocos nucifera L.) is considered a highly valuable and beneficial perennial crop in our country. The basal portion of the coconut embryo enlarges during germination and forms a spongy structure, haustorium, which is an excellent source of essential nutrients. Since consumer preference is shifting towards healthy food and processed coconut products have immense scope in this sector, the study was conducted to standardize the process variables for osmo-dehydration of coconut haustorium and to evaluate the nutritional qualities of the osmo-dehydrated product. Methods: The present study involved the development of osmo-dehydrated coconut haustorium by standardizing the process variables, viz., osmotic solution concentration and immersion time. Mass transfer, physical, biochemical and sensory parameters were analysed to evaluate the nutritional qualities and consumer acceptance. Result: The results on biochemical properties revealed that an increase in concentration and time of immersion increased TSS, total sugar, reducing sugar, ash and mineral content. The process variables were standardized for the development of osmo-dehydrated coconut haustorium with optimum mass transfer characters, better nutritional qualities and consumer acceptance, which has application in the food industry.
