Caracterización fisicoquímica de oleogeles de aceite de aguacate (Persea americana) y sacha inchi (Plukenetia volubilis)

Abstract

Debido a las consecuencias que presenta en la salud una dieta poco saludable y con gran contenido de grasas trans, se han desarrollado alternativas alimentarias para el cuidado de la salud, entre ellos, los alimentos naturales con el mínimo aporte de carbohidratos y de grasas saturadas. Por lo anterior, se propuso la formulación de oleogeles libre de grasas trans, a partir de emulsiones (w/o), usando aceite de aguacate y sacha inchi, estructurados con diferentes emulsificantes. Se consideró un diseño factorial 3x3, donde se varió el tipo de emulsificante: lecitina, monoesterato de glicerilo y la relación entre el aceite de aguacate y el aceite de sacha inchi para la fase oleosa del sistema oleoestructurado. Se obtuvo un producto con tintes verdosos y amarillos, cuya cromaticidad b* en sistema Cielab es afectado por el tipo de emulsificante, tomando tonalidades más amarillas, cuando se usa la mezcla lecitina–Monoesterato de glicerilo . Las formulaciones, con una relación de aceites 70/30 usando Lecitina, como emulsificante y la formulación con una relación de aceites 80/20 y usando Monoesterato de glicerilo, mostraron los mejores resultados en términos de fuerza firmeza, en contraste con las margarinas comerciales, cumpliendo con los requisitos fisicoquímicos, establecido en las normas vigentes para aceites y margarinas, como son: índice de pe- róxido (<10m-eq O2/kg de grasa), acidez (<0,8% de ácido oleico) y contenido de humedad (≥16% b.h).
