BACKGROUND Phytic acid and phytates can interact with biomolecules, such as proteins and carbohydrates, and are anti-nutritional factors found in food and feed. Therefore, it is necessary to remove these compounds in food and feed processing. Phytase can hydrolyze phytic acid and phytates to release a series of lower phosphate esters of myoinositol and orthophosphate. Thus, the purification and...

In this study, we evaluated vitamin D and mineral (iron, zinc, magnesium) transfer to the bolus aqueous phase during digestion of meals with/without pulses. We performed in vitro digestions using test made either i) beef and/or semolina chickpeas, or ii) potatoes supplemented not with fibers, phytates, tannins saponins. Chickpea presence led a decrease bioaccessibility (?56%, p ? 0.05) solubili...

Phytases are a group of enzymes capable of releasing phosphates from phytates, one of the major forms of phosphorus (P) in animal feeds of plant origin. These enzymes have been widely used in animal feed to improve phosphorus nutrition and to reduce phosphorus pollution in animal waste. This review covers the basic nomenclature and crystal structures of phytases and emphasizes both the protein ...

Phytate is the major storage form of phosphorus in seeds and so is a common dietary constituent. Excessive ingestion of undegraded phytates can cause mineral deficiencies in humans. In addition, phytic acid is antineoplastic in animal models of both colon and breast carcinoma. There have been no previous studies quantifying phytase activity in the human small intestine although it is present in...

This study characterized the most cultivated and consumed yam (Dioscorea) cultivars within the Ghanaian yam germplasm based on their chemical composition and anti-nutritional factors. Matured yam cultivars grown under the same climatic and edaphic factors were harvested from the Roots and Tuber Conservatory Division of the Council for Scientific and Industrial Research-Plant Genetic Resources R...

health and wellbeing.1 Consequences of severe zinc deficiency have been documented in several populations worldwide.2 The most widely used approach for the assessment of zinc status, particularly in a large population study, is the determination of circulating concentration of either serum or plasma zinc.3 Mild to moderate zinc deficiency is common in several developing countries, as the common...

ABSTRACT Cowpea is a socioeconomically important legume in the Northeast region of Brazil, and most grown consumed type bean, representing main source low-cost vegetable protein for rural urban populations this region. The objective work was to characterize proximate composition, minerals, tannins, phytic acid, cooking quality whole grains cowpea from commercial cultivars BRS Aracê, Inhuma, Xiq...

Consumption of dry beans is limited by long cooking times thus high fuel requirement. The bioavailability of nutrients in beans is also limited due to presence of antinutrients such as phytates and tannins. Little research has been done on combined processing methods for production of nutritious fast cooking bean flour and the effect of combined treatments on nutritional quality of beans has no...
