Some of the basis used to distinguish among varieties of tomatoes are the shape, bunches, the thickness of the meat, and water content. Based on the shape or appearance, tomatoes are classified as follows:

Must be Cleaned
Newly harvested fruits are usually separated by size and quality (grading). Determination of fruit quality based on health, toughness, cleanliness of the size, weight, color, shape, maturity, freedom from foreign substances and disease, as well as damage by insects and mechanical injuries. Category of quality that is commonly used is an extra class, class 1 and class 2.

Once sorted, tomatoes must be cleaned and washed to remove dirt on the fruit. Manure is usually a sprinkling of soil, dust and chemical substances (drugs and fertilizer spray). Apart from giving an impression of dirty, splashing soil can also carry diseases and some harmful microbes. Chemical substances that attach to the fruit, especially pesticides, if present in excessive amount can cause poisoning.

Storage of tomatoes must be done at temperatures not too high, usually carried out at room temperature. However, it would be much better if the tomatoes are stored at a lower temperature, namely in the refrigerator. High temperatures can damage the quality of stored tomatoes. Cold storage may slow the process of maturity, reduce susceptibility to microbial attack, reduce water losses, and maintain levels of vitamin C.[from]
