In watermelon fruit, the dominant soluble sugars are fructose, sucrose, and glucose, and the dominant organic acids are malic acid, citric acid, and oxalic acid.
Which fruit is rich in citric acid?
Among fruits, citric acid is most concentrated in lemons and limes,1 comprising as much as 8% of the dry fruit weight. A major source of citric acid in vivo results from endogenous metabolism in the mitochondria via the production of ATP in the citric acid cycle.
Is watermelon citric fruit?
Fruits that are not from the citrus family include apples, pears, watermelon, raspberries, blackberries, blueberries, melons, bananas, kiwi and more.
Is watermelon a high acid fruit?
Melons – Watermelon, cantaloupe and honeydew are all low-acid fruits that are among the best foods for acid reflux.
Is there citric acid in melons?
Sweet melons have a low organic acid content. Citric acid is the major organic acid in the sweet melon cultivars studied, with levels of about only 0.2% fresh weight; malic acid levels are even lower (Leach et al., 1989; Lindner et al., 1963; Sweeney et al., 1970; Wang et al., 1996).
Is Apple a citric acid?
Fruit acidity in cultivated apples is majorly determined by malic acid, which accounts for up to 90% of total organic acids [6]. Citric acid also exists in mature apple fruits; however, it exhibits a very low to undetectable concentration in cultivated apple [14,15].
What foods have no citric acid?
Here is a list of foods without citric acid:
- Bananas. Bananas are at the top of the list of foods that do not contain citric acid.
- Watermelon.
- Amaranth.

Do bananas have citric acid?
On the opposite end of the citric acid spectrum are foods without citric acid. These fruits include: Bananas.
Which fruit is not a citrus fruit?
Although pineapples have quite a bit in common with citrus fruits (like taste, Vitamin C content and a love of warm weather), they are not actually related to one another.
Does Mango have citric acid?
The most important pigments of mango fruit include chlorophylls (a and b) and carotenoids. The most important organic acids include malic and citric acids, and they confer the fruit acidity.
What is the most acidic fruit?
These have low pH levels, which means they are acidic. The most acidic fruits are lemons, limes, plums, grapes, grapefruits and blueberries. Pineapples, oranges, peaches and tomatoes are also high in acid.
Does watermelon cause stomach acid?
Watermelon can be acid-producing. Consign it to a mixed fruit salad only. Eat smaller portions. Your stomach detects large amounts and pumps out more acid.
What are the benefits of watermelon?

Does cucumber have citric acid?
Cucumbers with an endocarp pH near 3.5 have been observed to have citric acid concentrations as high as 73 pmoles/g or 1.4% on a wet weight basis.
Which vegetables have citric acid?
What are some fruits and vegetables that contain citric acid? Citric acid occurs naturally in lemons, limes, pineapples, grapefruits, berries (not blueberries), tomatoes, broccoli, carrots, and some varieties of peppers.
What acids are in watermelon?
In watermelon fruit, the dominant soluble sugars are fructose, sucrose, and glucose, and the dominant organic acids are malic acid, citric acid, and oxalic acid.
Which acid is present in potato?
For example, malic and ascorbic acids, both of which are found in potatoes, co-chromatograph. To quantify each, ascorbic acid was determined immediately at 260 nm; malic acid cannot be detected at this wavelength.
Which acid is in tomato?
Hence, The acid present in tomatoes is Oxalic Acid .
Which acid is in banana?
The oxalic acid in bananas is present in some form other than calcium oxalate.
Do onions contain citric acid?
Glutamic acid was the most abundant organic acid (325 +/- 133 mg/100 g) followed by citric acid (48.5 +/- 24.1 mg/100 g) and malic acid (43.6 +/- 10.4 mg/100 g). There were significant differences between the onion cultivars in the mean concentrations of all of the analyzed parameters.
Do potatoes have citric acid?
– Potatoes contain citric, malic, quinic, succinic, fumaric, and soluble oxalic acid (in order of decreasing amounts). – In cucumbers malic acid notably exceeds citric acid. Both acids hardly change in concentration during ripening.
