Abstract:

Persimmon fruit is susceptible to injury; this fruit is under different loads from harvest to delivery to the customer. Bruise occurs due to injury during the various stages of handling, transport and packaging. In this study, some effective factors on level of bruise persimmon such as fall height and type of impact surface were studied. Also some physical and storage properties of this product before and after impact testing at room temperature were investigated. The effect of these factors on bruise persimmons were analyzed by using factorial experiment in a completely randomized design with three levels of fall height of 15, 30, 45 cm, three levels of hitting such as wood, plastic, steel with same thickness of 6 mm and a total of 27 treatments with three replications. Analysis of variance showed that the effect of fall height and impact surface material on the bruise level was significant at the 5% level (p<5%). After 6 days storage of persimmons at room temperature the length from 74.44 to71.16 mm, width from72.82 to 69.14 mm, thickness from 48.87 to 45.09 mm, weight from 175.98 to 165.23 g, the arithmetic mean diameter from 65.38 to 61.80 mm, the geometric mean diameter from 64.20 to 60.51 mm, coefficient of sphericity from 0.86 to .085, surface area from 129.47 to 115.27 cm2, volume from 139.35 to 116.72 cm3 and density from 1.26 to 1.41 (g /cm3) changed.
