Modified atmosphere packaging is widely used to prolong the shelf life of many oxygen‐sensitive items including food, pharmaceuticals, work of art and so on. For food packaging applications, we investigated the effectiveness of oxygen scavenging coatings and flexographic printing ink formulations made using water soluble and water insoluble ascorbate enzyme systems. The present study summarizes the effects of various parameters on the oxygen scavenging rates and other performance aspects of the formulations. It is shown that; the initial oxygen scavenging rate can be increased by increasing the surface area of Calcium Ascorbate crystals and addition of catalyst or edible oil; addition of a catalyst like TiO 2 or Alumina and an edible oil in Ascorbate and laccase‐based formulations induces a synergistic effect upon the rate of scavenging oxygen from the packages; an efficient oxygen scavenging coating formulation can be made using water soluble Calcium Ascorbate and insoluble Ascorbate Palmitate containing enzyme and substrate; designing an efficient oxygen scavenging formulation using water insoluble Ascorbate Palmitate can reduce or eliminate formation of effluent which has potential to change the aperral of food items inside the package; an adverse effect of some binders which cause a reduction in the oxygen scavenging rate can be eliminated by making blends of different binders.
