Natural Acids of Fruits and Vegetables: Food items like fruits and vegetables contain acid components. According to the concentration of acidity in the foods, the taste and flavor of the foods increase and decrease. Normally, foods that contain high acidic value can act as a source of health depravity and beneficial for the right usage. But the wrong usage of such foods can cause massive health issues too. So, it is relevant to have an eye on the various foods that have the highest concentration of acidity and the lowest concentration of acidity. Normally the vegetables don’t hold the highest acidity rate as compared to the fruits. Let’s explore more about the list names of acids present in fruits and vegetables!

Types of Acids
Here is the names of acids present in fruits as well as the names of acids present in vegetables.
Ascorbic Acid
Ascorbic acid is always known as vitamin C. As individual bodies cannot make their vitamin C. The Food and Nutrition Board suggests that you eat between 75 and 120 milligrams per day into food or supplements. Vitamin C is connected with the prevention of a diversity of diseases, including, age-related macular degeneration, cancer, cataracts and the common cold.
Malic Acid
Malic acid is a compound found in certain fruits and wines. It is sometimes used as medicine. Malic acid is used most regularly for dry mouth.
Tartaric Acid
Tartaric Acid is a white crystalline dicarboxylic acid observed in many plants, especially tamarinds and grapes. Tartaric acid is used to produce carbon dioxide with sodium bicarbonate following oral administration.

Oxalic acid
Oxalic acid is an organic compound found in many plants. These add leafy greens, vegetables, fruits, cocoa, nuts and seeds. In plants, it’s normally connected to minerals.
Citric Acid
Citric acid is naturally existing in a variety of various fruits and vegetables. Foods high in citric acid include berries like raspberries and strawberries and citrus fruits like lemons and limes. Citric acid is most powerful in lemons and limes, and their juice contains 1.44 and 1.38 grams of citric acid per ounce, respectively. Citric Acid weightage in different fruits and vegetables are given below :
- Lemons – 4.08.0
- Grapefruit – 1.22.1
- Tangerines – 0.91.2
- Oranges – 0.61.0

pH Value and Measurements
The ph value is the estimated value for the calculation of the concentration of the acidity in food content. The value from 0 to 14. The scale represents 0 for the highest acidity rate and 0 for the alkaline rate. The in-between 7 stands for the neutral rate. Commonly there are acids like
- Lactic acid
- Acetic acid
- Formic acid
- Citric acid
- Oxalic acid
- Malic acid
- Tartaric acid
