Antioxidants alcoholic beverages

Furthermore, polyphenolics present in wine, of which flavonoids are important components, have been suggested to be responsible of the so called French paradox, that is, the unexpectedly low rate of mortality from coronary heart disease in French population despite an unfavourable exposure to known cardiovascular risk factors such as high saturated fat consumption [19-21]. Epidemiological studies in USA [22] and Denmark [23] reported that moderate red wine drinkers had a lower risk of coronary artery disease than participants with no alcoholic beverage preference. However, controversial results about the antioxidant capacity of human serum after red wine consumption have been reported [24-27]. It is therefore uncertain whether wine constituents other than alcohol add to the cardioprotective effects of red wine. 

FIGURE 14.1 Antioxidative properties of selected alcoholic beverages (based on Bartosz et al., Biochem. Mol. Biol. Int., 46, 519, 1998). The high antioxidative activity of beers may, to a considerable extent, result from the addition of antioxidants, vitamin C in particular. 

The opposite must be said in the case of alcoholic beverages. Experimental results did not indicate that they might play a role in the potentiation of cancer risk. This notion was somehow supported by the epidemiological studies carried out in France, which lead to the discovery of the so-called French paradox. Contrary to the common belief among this country s population, despite high alcohol intake, the frequency of heart failures and possibly also tumor incidence is lower than that in other states. Currently, it is postulated that antioxidant substances present in colored alcoholic beverages and particularly abundant in red wine (Figure 14.1) offer such protection.

Within a palette of the samples for organic and biological analysis, both CMCPEs and CP-biosensor have been employed for determination of a wide variety of compounds in (i) soft drinks (ii) alcoholic beverages (beers, ciders, and wines) (iii) vegetable oils (iv) food dyes, coloring additives, and antioxidants (v) industrial detergents and plastics and (vi) human tissues and fluids (kidney and liver cuts, spinal fluid, whole blood, serum, urine, and saliva). Among less frequently analyzed (vii) environmental samples, the dominant specimens were, for example, natural and industrial waters (see [4, 5, 33] and table surveys therein).

MTCC has been isolated and identified from Allium macrostemon 71). Also, MTCC has been reported to be contained in various types of foods, such as alcoholic beverages, fermented products, flour, milk, fruit products and chocolate (72,73,74). MTCdiC has been also reported from seasoning sauces, soy sauces, yeast extracts, wine, vinegar, beer and fruit syrup (75). There are several reports on the biological activity of tetrahydro-P-carbolines. It was demonstrated that these compounds have strong antioxidant activity in several... 

Regarding antioxidants, the parameter total dietary antioxidant capacity (TDAC) can be taken to reflect antioxidant intake it is defined as the antioxidant capacity of all plant foods and beverages (alcoholic and nonalcoholic) consumed daily in a diet and may represent the amount of antioxidant units (Trolox equivalents) present daily in the human gut (Saura-Calixto and Goni 2006).

So what causes this unique effect of red wine Part of the story is the high trace element content in comparison with beer or spirits, but this is not all. White wine and red wine are very similar as far as the main components are concerned. Red wine, however, contains about 20 times more of polyphenol derivatives than white wine. Alcohohc beverages are pro-oxidants, which means that they increase the intensity of oxidation processes. Alcohol itself is responsible for this effect. Red wine, however, is an antioxidant (—>3.31) thanks to its polyphenol content. Antioxidants were very intensely researched in the 1980s and 1990s, which also contributed to the increasing interest in red wine. The presence of polyphenols is required for this effect, but this is still not the whole story.
