What is phenols in food?
Phenols in foods occur mainly as secondary metabolites of vegetables, often found in polymeric forms (polyphenols). Phenols from foods are mainly simple phenols (e.g., caffeic acid), flavonoids, the most varied and ubiquitous class (e.g., catechin, quercetin), stilbenes (resveratrol), lignans, and tannins.
What are phenols and example?
Phenols are widely used in household products and as intermediates for industrial synthesis. For example, phenol itself is used (in low concentrations) as a disinfectant in household cleaners and in mouthwash. Phenol may have been the first surgical antiseptic.
Are polyphenols nutraceuticals?
The present review discusses the action of grape polyphenols against diseases and the new polyphenol-rich products developed to be used as nutraceuticals. Grape polyphenols demonstrated effects such as maintenance of endothelial function, increase in antioxidant capacity and protection against LDL oxidation.
What is the meaning of phenolic?
noun. Definition of phenolic (Entry 2 of 2) 1 : a usually thermosetting resin or plastic made by condensation of a phenol with an aldehyde and used especially for molding and insulating and in coatings and adhesives.
What are the benefits of phenols?
Phenolic acids, readily absorbed through intestinal tract walls, are beneficial to human health due to their potential antioxidants and avert the damage of cells resulted from free-radical oxidation reactions. On regular eating, phenolic acids also promote the anti-inflammation capacity of human beings.
What are the different types of phenols?
Depending on the number of hydroxyl groups attached, phenols can be classified into three types.
…
Classification of Phenol
- Monohydric phenols: They contain one -OH group.
- Dihydric phenols: They contain two -OH groups. They may be ortho-, meta- or para- derivative.
- Trihydric phenols: They contain three -OH groups.
What is the other name of phenol?
carbolic acid
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula C6H5OH.
Where are polyphenols found?
Polyphenols occur naturally, can have antioxidant properties, and are more generally found in fruits, vegetables, cereals, dry legumes, chocolate, and some beverages, oils, and spices.

Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula C6H5OH.
What are the major functions of phenolics?
Phenolics play important roles in plant development, particularly in lignin and pigment biosynthesis. They also provide structural integrity and scaffolding support to plants.
What is phenol made from?
Phenol is derived from benzene and propylene. These raw materials are first used to produce cumene, which is then oxidised to become cumene hydroperoxide, before being split into phenol and its co-product, acetone. Phenol plays a major role in our everyday lives.
What is the uses of phenol?
Molecular biology finds the application of phenol in the extraction of nucleic acids from tissue samples for further investigations. Phenol is also used in the cosmetic industry in the manufacturing of sunscreens, skin lightening creams and hair colouring solutions.
What are phenolics good for?
Are there different types of polyphenols?
Polyphenols are classified on the basis of the number of phenol rings that they contain and of the structural elements that bind these rings to one another. They are broadly dived in four classes; Phenolic acids, flavonoids, stilbenes and lignans.
Where is phenol found?
The compounds are also components of many food stuff including fruits and vegetables. Phenol is found to be present naturally in coal tar and creosote. It is also produced during natural fires, and through benzene degradation in the atmosphere under the influence of ultraviolet light radiation [14].
What is the effect of phenol?
Exposure to phenol may cause irritation to the skin, eyes, nose, throat, and nervous system. Some symptoms of exposure to phenol are weight loss, weakness, exhaustion, muscle aches, and pain. Severe exposure can cause liver and/or kidney damage, skin burns, tremor, convulsions, and twitching.
What products use phenol?
Phenolics also can be used as an intermediate for industrial synthesis to make a variety of products, ranging from plastics, explosives, paints, fertilizers, textiles, aspirin and paper. Hydroquinone, a common phenol, is used as a reduction agent in photographic developing solutions.
What are the properties and uses of phenol?
Phenols are organic aromatic compounds containing -OH functional group directly attached with the aromatic ring with general formula C6H5OH. Phenol are widely used as antiseptic, disinfectant, anesthetic and household cleaning products. Phenol is also used as starting material or produce as an intermediate in industry.
Which foods contain phenols?
Phenols are found in some of the healthiest foods and supplements we consume. The foods highest in phenols are all berries, dark-skinned grapes, pomegranates and other fruits with dark red and purple pigments. In many cases it’s the phenols that make them healthy.
Where are phenols found?
Notable sources of natural phenols in human nutrition include berries, tea, beer, olive oil, chocolate or cocoa, coffee, pomegranates, popcorn, yerba maté, fruits and fruit based drinks (including cider, wine and vinegar) and vegetables.
Which products contain phenol?
Phenol is found in small quantities in cosmetics, paints, polishes, adhesives, lacquers, varnishes and solvents. It is allowed in consumer products up to 2.5% and soaps and shampoos up to 1% in the EU. It may also be found in smoked meat and fish products, and as a part of smoked flavourings.
What are some examples of phenolic?

What are the function of polyphenols?
Polyphenols, organic compounds found abundantly in plants, have become an emerging field of interest in nutrition in recent decades. A growing body of research indicates that polyphenol consumption may play a vital role in health through the regulation of metabolism, weight, chronic disease, and cell proliferation.
