Abstract:
... Maize zein was hydrolyzed for 0.5-5 h by alcalase or papain. Protein solubility increased (P < 0.05) with the degree of hydrolysis (DH) and was higher for alcalase-hydrolyzed zein than for papain-hydrolyzed zein. The zein hydrolysates with both enzymes consisted mostly of small peptides or amino acids nondetectable by 15% acrylamide gel electrophoresis. Alcalase-hydrolyzed zein exhibited a stronge ...

Abstract:
... Plants have developed sophisticated mechanisms for acquiring iron from the soil. In the graminaceous species, a chelation strategy is in charge, in order to take up ferric iron from the rhizosphere. The ferric iron chelation-strategy components may also be present in the aerial plant parts. The aim of this work was to search for possible roles of those components in maize leaves. To this end, the ...

Abstract:
... Phytate is the dominant storage form of phosphorus (P) in mature cereal and oil grains. Phosphorus bound in phytate is nutritionally unavailable to monogastric animals and thus contributes to water pollution because it is excreted in the waste. Also, phytate can chelate certain minerals and exacerbate human mineral deficiencies. Our primary objective was to develop a rapid and inexpensive method o ...
