Int J Chem Eng Appl. However, Hollman and Katan observed that quercetin glycosides from onions were absorbed far well than the pure aglycone. High dietary intake of fruits, vegetables and cereals is related to a decreased rate in chronic diseases. However, they affirm that fnolicos identify the cause s of this variability of the metabolic fate of coffee metabolites remains very difficult. For example, extrusion cooking causes decomposition of heat-labile phenolic compounds 3.

In this study, the mechanism in which ferulic acid is absorbed will be explained as a model of dompuestos phenolic acids. Bioavailability of dietary phenolic compounds: Molecules as proteins, lipids or DNA, are known to function as a target for these free radicals, which may lead to a deteriorative process called oxidation 2, Several epidemiological studies relate a decreased rate of chronic diseases in population with high intake of fruits, vegetables and cereals. Previous studies of quillay honey conducted by our investigation group showed the presence of fenoliocs such as chlorogenic acid, caffeic acid, syringic acid, p-coumaric acid, gallic acid, quercetin, rutin and naringenin Montenegro et al.

Current knowledge of food sources, intake, bioavailability and biological effects. The lowest and highest polyphenol contents are shown in bold. Mechanism of Absorption of Phenolic Acids Nowadays, the precise mechanism of absorption of fennolicos compounds is being studied. Hence, there is an increasing need in knowing the possible contribution on health of these compounds.

Phenolics dietary intake it is affected by the food availability, every country and seasons offer a different wide range of possibilities; besides, the quantity and frequency of exposure to particular compounds is determinant.

Finally, it is recommended as highly renolicos that each factor that affects polyphenols bioavailability must be considered to be properly used in the pharmacological industry.

ffnolicos Mass spectra in the structure analysis of flavonoids. So it is concluded that the phenolic composition depends greatly on the type and variety of cereal. Reactive species of oxygen ROS are relevant mediators and influential factors in the development of colorectal cancer A convenient and safe O-methylation of flavonoids with dimethyl carbonate DMC.

The content of total phenolic compounds and flavonoids were determined by the Folin-Ciocalteau and aluminum chloride colorimetric methods Quettier et al. Authors fenolicox that there is no conflict of interest when drawing the manuscript.

Figure 2 shows the comparison of flavonoid content of honey samples and their separated phenolic extracts. Major phenolics in apple and their contribution to compuuestos total antioxidant capacity. In nutrition science, bioavailability is defined as the fraction of an ingested nutrient or compound that reaches the systemic circulation and the specific sites where it can exert its biological action.

The low absorbance of the reaction mixture showed high antioxidant activity. Compr Rev Food Sci F.
