Empleo de fitasas como ingrediente funcional en alimentos Application of phytases as functional ingredient in foods

Abstract

Algunos métodos empleados durante el procesado industrial de cereales y leguminosas producen una reducción en la concentración de ácido fítico presente, sin embargo, ésta reducción o inactivación es sólo parcial. Con la finalidad de mejorar la hidrólisis del ácido fítico, se ha comprobado que la adición de fitasas exógenas (myo-inositol hexafosfato fosfohidrolasas) procedente de diferentes orígenes puede tener una importante eficacia en alimentación animal. Diversos estudios sobre el empleo de fitasas exógenas en alimentación humana han demostrado un gran potencial para su empleo en mejora de la disponibilidad mineral, pudiendo esta capacidad ser utilizada para reducir el elevado riesgo que presentan ciertos grupos de la población expuestos a padecer déficits minerales como los vegetarianos, los niños alimentados con fórmulas infantiles elaboradas con soja o los habitantes de países en vías de desarrollo en los que alimentos ricos en ácido fítico como los cereales y las leguminosas son la base de su nutrición. No obstante, en los últimos años han surgido evidencias que demuestran que el ácido fítico ejerce una importante acción beneficiosa sobre el organismo.Various food processing and preparation methods result in a reduction in the phytate content of cereals and legumes. However, in general during these processes, phytate is not fully hydrolysed. To alleviate the aforementioned problems in the production of animal feeds, exogenous phytases (myo-inositol hexaphosphate phosphohydrolases) have been widely used. There is great potential, therefore, to use this class of enzymes in the processing and manufacturing of food for human consumption given the capacity to improve mineral bioavailability. This is seen as a way to reduce the risk of mineral deficiency in vulnerable groups including; child-bearing women; strict vegetarians; babies consuming soy-based infant formulas; and the inhabitants of developing countries. There is, however, growing evidence to demonstrate the beneficial role played by phytic acid in all human organisms.
