The composition and amount of phenolic compounds in cereals has been many times investigated. , 2003). , 2003). , 2003). Phenolic compounds and their influence on the sensory characteristics of rye were studied in detail. Water-soluble and water-insoluble phenol fractions were separated and analysed by HPLC (phenolic acids and alkylresorcinols) while lignans were separated and quantitated by GC-MS. 17. , 2008). The impact of high pressure on the interaction of aroma compounds with various maize starches has also been investigated.
