To investigate the effect of gamma irradiation on the nutritional quality of maize and sorghum grains, packs were exposed to doses of 0 and 2 kGy in a 60 Co package irradiator. Irradiated and nonirradiated samples were stored at refrigeration temperatures. Proximate composition, minerals content, minerals bio-availability, tannins content, phytic acid content, protein fractions and in vitro pro...

Phytic acid, the main storage form of phosphorous in plants cannot be digested by monogastric animals and is excreted into environment. This compound also has antinutritional effect due to its negative charge which makes it able to chelate minerals and organic elements like calcium, iron, zinc and amino acids to provoke malnutrition. Alarming increase in eutrophication and cost of supplementati...

Camelina sativa is an oilseed crop becoming important in North America and Europe for biodiesel production. The use of Camelina flours in animal diet may be limited by antinutritive compounds. The content of glucosinolates, phytic acid, sinapine and condensed tannins was evaluated in twelve accessions of Camelina sativa. All compounds showed significant differences among genotypes. Only the con...

Phytic acid (PA) has been recognized as a potent antioxidant and inhibitor of iron-catalyzed hydroxyl radical formation under in vitro and in vivo conditions. Therefore, the aim of the present study was to investigate, with the use of HPLC/MS/MS, whether PA is capable of inhibiting linoleic acid autoxidation and Fe(II)/ascorbate-induced peroxidation, as well as Fe(II)/ascorbate-induced lipid pe...

Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
