AB  - The contents of total and available niacin, carotenoids, tocopherols, as well as soluble free, conjugated and insoluble bound phenolic compounds was determined in untreated, alkaline-cooked and sprouted kernels of white, sweet and yellow maize. Antioxidant capacity of untreated maize kernels and processed flours was evaluated, too. There was a considerable increase in soluble free and conjugated phenolic compounds contents of maize flour after alkaline cooking and sprouting. The content of total soluble free and conjugated phenolics in maize masa flour and sprouted flour was increased by 35% to 56% and by 46% to 92% as compared to the contents originally present in untreated kernels, respectively. Contrary, conditions of alkaline cooking had strong effect on the loss of bound phenolic compounds, as well as niacin, carotenoids and tocopherols in maize flour. Despite of this, our findings imply that both alkaline cooking and sprouting enhance the antioxidant capacity of maize kernels. According to our results, sprouting is a more effective method to release bound phenolics as well as to enhance the nutritional and functional value of the maize flour. Therefore, sprouted maize, as a rich source of bioavailable phytochemicals, can be used to develop functional maize-based foods.

AB  - The content of tocopherols, B vitamins, as well as free soluble, soluble conjugated and insoluble bound phenolic compounds was determined in untreated, steeped and sprouted wheat grains. Antioxidant capacity of whole wheat grains and their phenolic fractions was also evaluated. Sprouting significantly increased the levels of tocopherols, niacin, riboflavin, as well as free and bound phenolic compounds improving nutritional value and antioxidant capacity of wheat grains/flour. After sprouting for 5days, the content of total phenolics, flavonoids and ferulic acid calculated as the sum of its fractions was increased by 9.9, 30.7 and 21.6%, respectively. The content of -, +- and -tocopherols was increased for 3.59-fold, 2.33-fold and 2.61-fold respectively, while the content of niacin, as predominant B vitamin, was increased for 1.19-fold after sprouting. The total antioxidant capacity of untreated, steeped and sprouted whole wheat grains was 19.44, 20.37 and 22.70mmol Trolox Eq/kg, respectively. Sprouted wheat, as a rich source of bioavailable phytochemicals, should be used to improve the nutritional quality of food.

AB  - The nutritional composition, the phenolic profiles and antioxidant capacity of the floral pollen from maize genotypes were evaluated. In addition, the antioxidant capacity, browning and wavelength spectra of melanoidins were investigated in the pollen samples stored at 4 degrees C for 7 days, dried at 40 degrees C for 6 h and exposed to a temperature of 100 degrees C during 12 h. The results showed that different maize pollen samples had diverse nutritional composition, antioxidant capacity and phenolic compounds were a major contributor to their antioxidant activities. Sweet maize pollen with the highest content of total phenolics and flavonoids had the highest antioxidant capacity (104.38 mmol trolox eq/kg). Quercetin diglycoside was the most abundant flavonoid in all pollen samples. Floral maize pollen could be used as a functional food ingredients, and dietary supplement with therapeutic effects. However, pollen is very susceptible to processes of Maillard reaction and phenolics oxidation and these factors must be considered when considering its use.
