The addition of lipid and antioxidant in spite of lowering the
solubility and stability levels of the films and coating solutions
showed distinct improvement in the surface morphology of the
films. However, ghost granules remained even after adequate
gelatinization. S/G/L/A coating delayed change of ripening parameters
and L, a, b colour values of tomatoes coated with the different
coating solutions, which can be directly attributed to the antioxidant
activity of the green tea extract. Lipid addition to the starch
film significantly controlled the ripening of tomatoes. S/G/L/A
coating had microbe-barrier property. The edible coating formulation
of S/G/L/A thus was found to form a rigid and continuous fruit
coating that was able to extend the ripening period of tomatoes on
storage at room temperature along with a good microbe-barrier
property.
