“…It has been reported that during germination, de novo synthesis and activation of endogenous phytases with concomitant decrease in phytate content occurs in cereals and legumes (Agte, Joshi, Paknikar, & Chiplonkar, 1998;Liu, Amjad, Tzeng, & Rob, 1998). In the case of faba bean, phytate content was affected by germination; however, the tannin, which is a known inhibitor of mineral availability, was significantly decreased as a result of processing (Luo et al, 2010a).…”

“…Nos vegetais, o fósforo faz parte de uma molécula bastante complexa denominada hexafosfato de inositol ou fitato e pode compor até 81,00% do conteúdo de fosfato presente nos vegetais (Riche & Brown, 1996). De acordo com Kornegay (1999), o fitato está presente nas plantas de modo geral e contêm alta quantidade de fósforo (28,20%); apresenta ainda grande capacidade de quelação com outros minerais, o que lhe confere a denominação de antinutriente (Liu, 1998).…”

“…A enzima fitase está amplamente distribuída e pode ser encontrada nas plantas, em tecido animal e microrganismos; nas plantas ocorre em cereais, legumes e vários tipos de sementes, o que pode melhorar a disponibilidade de seus Tabela 3 -Disponibilidade aparente do fósforo (P) de alimentos de origem vegetal suplementados ou não com fitase para tilápias-donilo (% MS) (Sunflower meal) 26,42 ± 3,37 b 33,93 ± 1,51 a 33,41 ± 3,32 a nutrientes, principalmente minerais, em razão da presença natural desta enzima (Liu, 1998). De acordo com Kornegay (1999), o grão de trigo se destaca pelos elevados níveis da enzima fitase (até 2.957 uf/kg), enquanto o farelo de trigo apresenta aproximadamente 1.193 uf/kg, valores superiores aos descritos por esse autor para outros vegetais como o milho (15 uf/kg) e o sorgo (24 uf/kg).…”

“…Phytase (myo-inositol hexaphosphate phosphohydrolase) (PhyA) catalyzes the hydrolysis of phytic acid (myo-inositol hexaphosphate or phytate) into phosphorous compounds, which is an essential nutrient for animals [1] according to the reaction shown below. phytic acid + H 2 O phytase −→ inositol + PO 4 −3 Phytic acid is the main storage form of phosphate in grain seeds, pollen, vegetables, and oilseeds [2,3], but it is also considered an antinutrient due to its chelation ability, binding dietary minerals such as magnesium, zinc, and calcium [2].…”
