Interaction between gliadins and anthocyan derivatives.

The interaction of gliadins with some anthocyanins (e.g. myrtillin, malvin, keracyanin, callistephin) and anthocyanidins (e.

A novel chitosan derivative to immobilize alpha-L-rhamnopyranosidase from Aspergillus niger for application in beverage technologies.

alpha-L-rhamnopyranosidase (Rha, EC 3.2.1.

Foliar application of selenite and selenate to potato (Solanum tuberosum): effect of a ligand agent on selenium content of tubers.

The effect of a foliar spray of selenium on potatoes was investigated for 2 years. Amounts of 0, 50, and 150 g of Se ha(-)(1) were applied both as sodium selenate and as sodium selenite in water, either pure or with the addition of 0.15% of soluble leonardite as a source of humic acids (pH 7).

Fining treatments of white wines by means of polymeric adjuvants for their stabilization against browning.

Browning and maderization represent important problems for white wine stability. Essentially, this is due to polyphenol oxidation in the wine. The problem has been remedied by adsorption of polyphenol compounds with polymeric adjuvants (chitosans, scleroprotein, and polylactic acid) not used traditionally in wine-making.

A simple method for purifying glycosidases: alpha-l-rhamnopyranosidase from Aspergillus niger to increase the aroma of Moscato wine.
