The phytochemical screening revealed the presence of alkaloids, saponins glycosides, flavonoids, steroid, anthraquinone and tannic acids
in both extracts investigated.
1] extract, respectively, expressed in tannic acid
equivalents (TAE) (Table 1).
The main parameters that influence the production of tannase are tannic acid
concentration, humidity, type of substrate used, temperature, pH, incubation time and addition of different sources of carbon and nitrogen (LEKHA; LONSANE, 1997).
Processing acorns does take a decent amount of time because you have to remove the tannic acid
, so do a bit of research about how to eat acorns before you dive in.
or Hydrolysable Tannins are naturally occurring complex phenol-rich polymers; prevalent in a wide variety of herbs plants and fruits.
, or tannin, is a phenolic antioxidant that binds to allergenic protein fragments, forming insoluble complexes that may keep the allergenic protein from being released in the stomach and gut.

The study provides insights into whether tannic acid
can be used during food processing to reduce the allergenicity of peanut-based foods and beverages.
In this study, we used lipid soluble antioxidants such as thymoquinone, epigallocatechin-3-gallate, and tannic acid
as experimental agents for the conventional treatment to observe morphological changes in the LNCaP cell line.
Considerable amounts of experimental data on the antioxidant activity of both tannic acid
and gallic acids with emphasis on structure-function antioxidant activity have been reported .
It has also been described that certain polyphenols, namely tannic acid
and coumarins (Perez-Vicente et al.
It's not often that chemists find a quick, simple and cheap method for making things with widely available ingredients, but researchers have done just that: They've created elegant little capsules and coatings in water simply by mixing iron and a compound from plants called tannic acid
