Tomato which acid

Ascorbic acid, also called vitamin C, is the next most prevalent organic acid in fresh tomatoes, comprising about 0. In more practical terms, a medium-size fresh tomato contains about 10 milligrams of ascorbic acid, according to the U.

Department of Agriculture. The recommended daily requirement of ascorbic acid for adults ranges between 75 and milligrams depending on gender and pregnancy, so tomatoes are a relatively good source, but not as rich as other citrus fruit such as lemons, grapefruits or oranges. Ascorbic acid boosts immune system function and is needed to make collagen -- the elastic-like fibers in skin and other connective tissues. Like most other organic acids, ascorbic acid also displays antimicrobial properties.

Sirah Dubois is currently a PhD student in food science after having completed her master's degree in nutrition at the University of Alberta. She has worked in private practice as a dietitian in Edmonton, Canada and her nutrition-related articles have appeared in The Edmonton Journal newspaper. The most alkaline tomatoes are those that have been strained or vine-ripened.

Dietary alterations can help you reduce acid, especially if you are experiencing negative symptoms such as stomach cramps or acid reflux.

Tomatoes are high in acid, so avoid them if these symptoms arise. If symptoms continue despite dietary alteration, contact your health care professional. Citric acid is the most commonly found natural acid in tomatoes.

Citric acid is often used in food flavoring and as a preservative due to its ability to kill bacteria. It is particularly used in soft fruit drinks to provide that sharp flavor.

In addition to this, it is integral to the citric acid cycle in the body. This process pathway provides nearly two thirds of all energy in the human body, so it's an important acid to keep the body topped up on.

Citric acid can be a highly beneficial to your overall health as well. A December literature review published in the Korean Journal of Urology found that an increased intake of citric acid was linked to a reduced chance of developing kidney stones. This occurs because citric acid binds to urinary calcium, reducing the supersaturation of urine that can lead to kidney stones. Citric acid also binds to calcium oxalite crystals, preventing the excessive growth of crystals that would otherwise result in stones.

Along with a reduced chance of kidney stones, increased consumption of citric acid has been linked to a reduced risk of gout. According to the Mayo Clinic , gout occurs when uric acid is not dissolved in the blood properly, so it builds up and eventually forms painful crystals that cause inflammation in joints and may eventually result in a gout attack. An older study published in the journal Endocrine Research in tested a total of 70 subjects and found that increased citric acid intake also increased the acidity of urine and the excretion of uric acid, meaning that uric acid was less likely to build up and form crystals that could lead to gout.

Because tomatoes are high in citric acid, adding them to your diet may provide similar benefits. Ascorbic acid, more commonly known as vitamin C, is found in significant quantities in tomatoes. It's a highly beneficial vitamin for the body due to its role in cell maintenance and repair. According to MedlinePlus , vitamin C is necessary for:. The human body is not able to create and store vitamin C independently, so it's highly important that you get as much as you can through dietary means.

Sources of ascorbic acid go beyond tomatoes alone; it is actually quite common. Now you don't need to go and binge on any of these items just because the body doesn't produce ascorbic acid independently, but adding them and keeping them in your diet will certainly help keep levels high and boost your overall health.

As much as The most common sugars found in tomatoes are glucose and fructose , both of which play a key role in the production and release of energy in the body. The difference in the pH is because of the process that the tomatoes undergo to get delivered as these final products.

Canned products are typically more acidic in nature because there is a preservative added, also acidic in nature because of which the overall pH drops. In the case of tomato puree, these preservatives are present in more quantity moreover the tomatoes are itself more acidic for this particular end-use, hence the pH is even lowered. Though the pH of tomatoes is not that extreme and falls in the typical range of all the foods that we can consume, the acidity of tomatoes cannot be considered a problem for human health.

However, excess of tomatoes can lead to excess production of gastric acid leading to acidity and heartburns. This idea is a contradiction to the eastern medicinal philosophy where tomatoes are considered to be alkalizing food when digested as it will help lower the acidity of the blood and thus create an acid-alkaline balance in the body. There can be two possibilities of altering the acidity as we can choose the tomatoes more acidic as we do it in the canning process to increase the shelf life of the product by the addition of preservatives.

Therefore, in this section, we will focus on reducing the acidity of tomatoes which can be required for certain applications. In order to reduce the acidity, we have to essentially neutralize the acid by reacting it with an alkali. Therefore, a weak acid to be reacted with weak edible alkali and baking soda is the best choice for this. Cooking tomatoes with baking soda can help reduce the acidity which in turn will reduce the sour taste of tomatoes.

The quantity of baking soda to be used for this purpose depends upon the number of tomatoes undergoing this process and the acidity of these tomatoes.

The pH range of tomatoes is between 4. The tomato products are acidic in nature because of the presence of citric and malic acid, however, there are ways to alter the acidity and taste of tomatoes as well. The tremendous health benefits of tomatoes have to lead to great studies in the field of biochemistry and medication.
