The tomato is the fruit of a kind of food that has a high freshness when consumed. Tomatoes with vitamin C (Ascorbic acid) which has a sour taste so fresh taste when consumed. Then Are Tomatoes Acidic?
Tomatoes have a different acidity at each phase of the growth of fruit ranging from young fruits until completely cooked. Tomatoes are more acidic than young tomatoes are ripe with a pH content approach the 4.9. Tomatoes that have been packaged in tins will experience higher keasaaman because the process of canning will add a preservative substances tend to increase the acidity.
pH is the degree of acidity or basicity is used to express the level of acidity or basicity of a solution by. It is defined as the kologaritma activity of hydrogen ions (H +) are dissolved. Hydrogen ion activity coefficient cannot be measured experimentally, so that its value is based on theoretical calculations. The pH scale is not an absolute scale. He is both relative to a set of standard solutions whose pH is determined on the basis of an international agreement. Scale of 0 to 14 pH. The nature of the acid has a pH between 0 to 7 and alkaline properties have values pH 7 to 14. For example, orange juice and water battery has between 0 to 7 pH, while sea water and liquid bleach has the properties of the base (which is also called as alkaline) pH value of 7-14. Pure water is neutral or has a pH value of 7.
According to the Center for Food Safety and Applied Nutrition at the U.S. Food and Drug Administration, fresh tomatoes fall into the 4.3-4.9 range when it comes to acidity. For canned tomatoes and tomato paste, the pH range is 3.5-4.7. For tomato juice, the range is 4.1-4.6. Vegetables like celery, broccoli, carrots, romaine lettuce, and spinach typically have a higher (less acidic) pH range of 5-7, and fruits like apples, oranges, grapes, grapefruit, and blueberries typically have a range that include this 4-5 level but also dips down lower into the pH 3-4 range.

That's some information that I get from some site that describes keasamaan tomatoes and also the benefit that we can get from the fruit of the tomato. Indeed all types of fruit and vegetables have acidity and alkaline that is different in accordance with the character of land where he grows and also the type of fruit and vegetable.
