Two Step Conversion of Ferulic Acid to Vinyl Phenol
Journal Title: Archives of Organic and Inorganic Chemical Sciences - Year 2018, Vol 2, Issue 1
Abstract
The cereal industries produce several million tons of cereal brans every year which are good source of ferulic acid. There was no such chemical route to convert ferulic to vinyl phenol directly. Therefore, an alternative approach two step conversion of ferulic acid to vinyl phenol was developed for better and costly flavour by using chemical route to make it cost effective. Cereal brans are good source of ferulic acid. An approximate global production of 150 million tons of cereal brans have been reported in 2004. These by-products are extensively used as animal feed, but active research is being carried out in this field to produce higher value added products from these. Many literature review assesses the various biotransformations of ferulic acid and the role of microorganisms and plant cells in bringing about these transformations but no one have focussed to convert Ferulic acid to vinyl phenol chemically in two step system. Ferulic acid is also a precursor for 4-vinyl guaiacol (3- methoxy 4-hydroxystyrene), the transformation being catalyzed by the enzyme ferulic acid decarboxylase. 4-vinyl guaicol or vinyl phenol is nearly 25-30 times more costly than ferulic acid which makes the conversion, a highly value added process. 4-vinyl guaiacol and other vinyl phenols may be produced from free phenolic acids and contribute to either the desirable aroma of important food products. 4-vinyl phenol has clove or spice like and phenolic flavour characteristics and is an appreciable flavour constituent in certain beers and soy sauce. There were few studies on chemical route to convert ferulic to vinyl phenol majorly were reported by biological routes. Therefore, a fast and cost effective approach oftwo step conversion of ferulic acid to vinyl phenol was developed for valuable flavour by using cost effective chemical route.
