Where can I get gallic acid?
Gallic acid is found in the leaves of bearberry, in pomegranate root bark, gallnuts, witch hazel, sumac, tea leaves, oak bark, and many other plants, both in its free state and as part of the tannin molecule.
Is gallic acid harmful to humans?
In an acute oral toxicity study, at 5000 mg/kg p.o. signs of lethal toxicity were not observed. And in a subacute toxicity study, 1000 mg/kg p.o. was found to be non-toxic, indicating the safety of gallic acid.
Is gallic acid good for you?
Results: Several beneficial effects are reported for gallic acid, including antioxidant, anti-inflammatory, and antineoplastic properties. This compound has been reported to have therapeutic activities in gastrointestinal, neuropsychological, metabolic, and cardiovascular disorders.
What is high in gallic acid?
Food sources of gallic acid strawberry. grape. banana. blueberry.
What products contain gallic acid?
In nature, gallic acid and its derivatives are present in nearly every part of the plant, such as bark, wood, leaf, fruit, root and seed. They are present in different concentrations in common foodstuffs such as blueberry, blackberry, strawberry, plums, grapes, mango, cashew nut, hazelnut, walnut, tea, wine and so on.
What does gallic acid do for skin?
Gallic acid: Promotes even skin tone by reducing the visibility of sunspots. Reduces colour pigmentation such as dark undereye circles. Helps to minimise inflamed skin and redness.
What food contains gallic acid?
What is the pH value of gallic acid?
Results. We found that gallic acid produces two different radicals as a function of pH. In the pH range between 7-10, the spectrum of the gallate free radical is a doublet of triplets (aH = 1.00 G, aH = 0.23 G, aH = 0.28 G).
Is gallic acid an antioxidant?
Among various polyphenols, gallic acid (3,4,5-trihydroxybenzoic acid), a naturally occurring low molecular weight triphenolic compound, has emerged as a strong antioxidant and an efficient apoptosis inducing agent.
Do polyphenols help you lose weight?
Some research suggests that polyphenol-rich foods may aid weight loss. A 2011 study found that a diet rich in polyphenols may interact with bacteria in the intestines to support weight loss, especially when combined with a diet low in probiotics.
Why is propionic acid added to gallic acid esters?
Because of the presence of the three hydroxyls, gallic acid esters make very effective antioxidants. Free gallic acid would presumably make an effective antioxidant but its solubility in lipids is low. Thus, it is esterified with propionic acid to increase lipid solubility.
What are the applications of gallic acid?
Gallic acid and its derivatives have a large number of applications in various fields of science. In nature, these compounds are widely distributed in plants and fruits, and thus they are being used as food stuffs, preservatives, etc. directly or indirectly by human community.
Why is gallic acid added to polyunsaturated oils?
It is often added to polyunsaturated oils used for deep fat frying. PG is the n -propyl ester of gallic acid. Because of the presence of the three hydroxyls, gallic acid esters make very effective antioxidants. Free gallic acid would presumably make an effective antioxidant but its solubility in lipids is low.
