Abstract

The purpose of this research was to investigate post-harvest damage and performance of the current sweet tamarind wholesale package and present the developed packaging of minimum damage under simulated vibration. Methodology comprised (a) collection and analysis of current wholesale packages at random at retailer, (b) performance testing and evaluation of the current wholesale package compared with the developed wholesale package which consisted of the mixture between 5 mm. diameter foam ball and sweet tamarind at the varying Mixing ratio of the ball at 20%, 40%, 60% and 80% by container volume. The test was based on ASTM D999 method A2 standard and IST A Project 1A with vibration simulator and two cultivars of tamarind (Sithong and Sri-chompoo). The vibration was set at the frequency of 4 hz. and duration of I hour. The experiment was designed to be completely randomized design and analyzed by the use of Duncan's multiple range test with two Controlling factors (i.e. cultfvar and Mixing ratio). Results showed that post-harvest damage of sweet tamarind pod in the current wholesale packaging, which is corrugated paper box, was about 22.03% and 29.54% for Si-thong and Sri-chompoo respectively. The damage included crack, hair line crack, stem end crack, hole and mold. The current package damage after simulated vibration with Si-thong and Sri-chompoo was 1.9%, 7.8% respectively. The cultivar and the Mixing ratio significantly affected pod damage at the significant level of 5%.The damage (D) proportionally decreased with the Mixing ratio (r). The equation of relationship between pod damage and the Mixing ratio for Si-thong is D = -0.014r+1.823 (R2> 0.99) and for Sri-chompoo is D = - 0.089r+8.043 (R2> 0.97). The proper Mixing ratio of the ball was 20% corresponding to the lowest packaging cost of 1.05 (Si-thong) and 1.0 (Sri-chompoo) USD. per kilogram of tamarind respectively.
