  The importance of antioxidants and place in today’s scientific and technological studies

  Zehiroglu, Cuma; Ozturk Sarikaya, Sevim Beyza

  Antioxidants have become scientifically interesting compounds due to their many benefits such as anti-aging and anti-inflammatory. Today, it is still used in many areas. In food technology, antioxidants are added to many foodstuffs in order to enrich the foods and eliminate the problems. Therefore, studies to determine the antioxidant activities of natural foods and their components are also continuing rapidly. Antioxidants have also been replaced in the encapsulation studies used for the preservation and stabilization of food components. Of course, preservation of foods is as important as their production. The latest packaging techniques for food preservation are edible films and coatings. The protective function of edible films and coatings can be improved by the addition of antioxidants. Unlike these, studies on plants and animals have been investigated in vivo in terms of how the antioxidant activity changes as a result of metabolic activities. The role of antioxidant enzymes in these studies is quite large. Many results have been found for the elimination of diseases by either in vivo or in vitro studies regarding antioxidants. Thus, the importance of antioxidants increased with the use in pharmacology, cosmetics and medicine. In this study, we tried to bring a current perspective to antioxidants played an active role in many fields by combining the technological applications and scientific studies of antioxidants. In order to further customize the issue, we have done this especially for the food and health field and we have tried to emphasize the importance of antioxidants in this way.

  A procedure for separation and enrichment of Cd(II) and Ni(II) ions based upon carrier element-free coprecipitation by using an organic coprecipitant, 2-{4-[2-(1H-Indol-3-yl)ethyl]-3-(4-methylbenzyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl}-N-(3-fluoro-phenylmethyliden) acetohydrazide, prior to their flame atomic absorption spectrometric detections has been developed. The effects of varied experimental conditions on the performance of the developed method such as pH, sample volume, amount of coprecipitating agent, etc. were evaluated in detail on the recovery of analyte ions, and the influences of some anions and cations were investigated. The limits of detection for Cd(II) and Ni(II) ions based on three times the standard deviation of the blanks (N: 10) were obtained as 0.70 g L-1 and 1.21 g L-1, respectively. The accuracy of the method was tested by analyzing a certified reference material and by spike tests. The method was applied to determine the levels of cadmium and nickel in stream and sea water, rice, red lentil, and wheat samples.
