Abstract

This experiment is aimed at prediction of shelf life of canned Palmyra palm Tender Fruit Endosperm (PTFE) which is an essential step in launch of a new product to the consumer market. To determine the suitability of canned PTFE to support long-term storage during off seasons, accelerated shelf life studies were performed on representative samples kept in three different simulated temperatures 35ºC, 45ºC and 55ºC. The change in physical properties assessments were employed to establish shelf life endpoints for canned PTFE. Development of off-colour and presence of haze was observed through change in OD value of syrup and taste change was observed through TSS and pH values in accelerated conditions. The canned PTFE had F value of 10.19 minutes to reach the commercial sterility. The canning technology is an adaptable one where there is no usage of any chemical preservative and in a convenient package form; additionally the use of sterilization temperature and pressure combination ext
