Abstract:
Starfruit, Carambola averrhoa var. B 10, were coated with different concentration
level of palm-based coating. Three different concentration level of palm-based
coating were classified based on the ratio of Palm wax to the ratio of 5000g of Palm
oil. This was done to obtain different concentration level of coatings which were
assumed as various thickness of coatings. Treatments includes Tl (500g of Palm
wax with 5000g of Palm oil) with ratio 1: 10, T2 (1500g of Palm wax with 5000g of
Palm oil) with ratio 3: 10, T3 (2500g of Palm wax with 5000g of Palm oil) with ratio
5: 10 and TO as the control. Each treatment had 3 replicates and each replicates had
54 samples of Starfruits. Samples were arranged in each personal boxes for each
replicates and were located at the laboratory with an ambient temperature. 3 main
parameters has been used throughout this experiment which are the weight loss, fruit
colour and Total Soluble Solid (TSS). At the end of this research, it was found that
level concentration of Palm-based coating treatments in 5: 10 ratio shows the best
result in parameters chosen which are weight loss and fruit colour, on the postharvest
shelf life of Starfruit (Averrhoa carambola) during 8 days of storage period at
ambient temperature. However, there were no significant difffrence (p < 0.05) on the
g
th
day of storage period based on the analysis done.
