Comparison of physicochemical properties of several tomato varieties


Abstract
For the elucidation of some information on processing properties of tomato, physicochemical characteristics of fruits were analysed for two group of cultivation pattern, non-proped cultivation (5 varieties) and groped cultivation (4 varieties). Weight, length, width, thickness and specific gravity were greater in the groped cultivation group than in the non-groped. Among the groped varieties, Master 2 showed the greatest values and 76Mo11-3-1-2-2 the smallest. Among the non-groped, weight, length, width and specific gravity were greatest in Jinhong and thickness was greatest in Good Hope and smallest in 79078¡¿ARC. Hardness showed significant difference only among the non-groped resulting in the lowest value in 79078¡¿ARC. Fruit sphericity was greater in the non-groped among which Good Hope was the greatest. In fruit color the non-groped showed greater trend in dominant wavelength, especially in Good Hope. No significant difference between group was found in lightness and % chroma. Sugar content showed higher trend in the non-groped and highest in Master 2. Acidity was significantly higher in the non-groped and highest in Good Hope. There was no difference in pH. Vitamin C was difference between group but higher trend in 79078¡¿ARC. Viscosity was no difference between group but higher trend in 79078¡¿CL1561F6 of the non-groped and 76Mo11-3-1-2-2-of the groped.
