Özet

The purpose of this study was to determine the effect of AVG treatments on some physico-mechanical properties and color characteristics of apple. Three levels of AVG as AVG-0 (0 mg L-1, non-treatment), AVG-1 (100 mg L-1) and AVG-2 (300 mg were used. The geometric mean diameter, fruit mass, bulk density increased from 69:03 mm to 70.40mm, from 186.8 g to 191.0 g, and from 352.5 to 374.3 kg m(-3), whereas, the sphericity of apple decreased from 1.087 to 1.078 as AVG doses increased, respectively. The surface area, projected area and volume increased with AVG doses. L* value increased from 43.75 to 45.88, whereas, chroma decreased from 40.07 to 39.68 as AVG doses increased from 0 to 300 mg respectively. The static coefficients of friction on rubber and galvanized metal linearly increased from 0.272 to 0.337 and froth 0.268 to 0.290 with an increase in AVG doses. The fruit-removal-force and skin firmness of apple linearly increased from 13.85 to 24.07 N and from 106.14 to 109.22 N in magnitude with an increase in AVG doses.
