determination of saome physical properties of strawberry fruit (selva cultivar)

in the present research, the physical, nutritional and chromatic properties of strawberry (fragaria xananassa), selva cultivar were studied. the values for mass, diameter, length, geometric meandiameter and sphericity of strawberry fruit at 91.07% moisture content (d.b.) were 11.885 g, 28.260mm 29.697 mm, 28.585 mm and 0.971 respectively. at the same moisture content, volume, truedensity, bulk density, porosity and hardness were 12.325 cm3, 1068.880 (kg/m3), 474.330 (kg/m3),51.11%, 8.606 cm2 and 3.632 n respectively. static coefficient of friction on the steel, galvanizediron, plywood and rubber surface measured as 0.415, 0.439, 0.473 and 0.575 respectively. analysisof variance showed that there was a significant difference between the surfaces of various materialsand only galvanized steel and iron surfaces were not significantly different. the color parametersl*, a*, b* and color intensity were 29.6, 29.7, 28.2 and 40.95, respectively. the values for ph, tss,total acidity, vitamin c, dry matter and ash were 3.6, 7%, 3.8%, 64.13 (mg/100g), 8.90(mg/100g)and 0.787(mg/100g), respectively.
