2. Mitigación de la formación de acrilamida en papas fritas tipo chips mediante la adición de antioxidantes fenólicos de Inca muña (Clinopodium bolivianum)
The aim of this study was to evaluate the influence of Inca muña phenolic antioxidants in the reduction of acrylamide (AA) in potato chips. The potatoes were cut into 2 mm thick slices, the addition of antioxidants was evaluated by immersion at atmospheric pressure and by vacuum impregnation (VI) at 80 kPa for 10 min. In both cases, two antioxidant concentr

9. Inhibitory Effects of Some Flavonoids on Thioredoxin Reductase Purified from Chicken Liver
ABSTRACT Thioredoxin reductases (TrxRs) are selenocysteine-containing flavoenzymes that reduce Trxin NADPH-dependent manner. In the view of the direct vital role of TrxR in a wide range of biochemical and physiological processes, methods to inhibit this enzyme are clinically important. TrxR has recently emerged as a new candidate in anticancer drug investiga
