ChutichudetPrasit 1201161Pitaya fruit is a popular fruit in Thailand due to its attractive reddish colour and highly delicate flavour. However, the shelf life of this fruit is rather short under ambient condition. The objective of this research was to extend the fresh quality of pitaya fruit by using a natural coating substance, chitosan. The effects of chitosan coating in extending the postharvest life of pitaya fruits relating to weight loss, stomatal conductance, stomatal size in terms of stomatal width and stomatal length, stomatal aperture, wilting percentage and shelf life were investigated. The experiment was arranged in a completely randomized design, composed of coating with chitosan at four levels (0, 1, 2 and 3%) and then stored under ambient temperature. Each treatment consisted of four replicates, ten fruits per replication. The results indicated that fruits treated with 3% of chitosan had the least attributes of stomatal conductance, stomata size in terms of stomatal width, stomatal length and stomatal aperture. In addition, treatment of 3% chitosan also showed the lowest wilting percentage and gave the maximal postharvest life of 8.17 days.]]>Ariffin, A.A., J. Bakar, C.P. Tan, R.A. Rahman, R. Karim and C.C.
