Abstract
Active packaging promotes shelf life extension and quality control of a food
product. Unfortunately, compared to regular plastics, starch-based products exhibit
some disadvantages mainly due to the highly hydrophilic nature of starch. Usually,
strong hydrogen bonds hold the starch chain together, causing starch granules not to
dissolve in cold water. This hydrophilic nature of starch causes low water stability and
high sensitivity to moisture, which limits the development of starch-based materials.
The properties of films produced from starch showed rigidity and reduced flexibility
of the films. Thus, an addition of antioxidant to the packaging starch-based can
improve the overall protection toward the products. Starch packaging provides
moderate barrier to the oxidation, solubility, and water vapor permeability. The
addition of antioxidant is needed to enhance the quality of the packaging. High number
of additives can be added to the matrix, to improve the characteristics of the produced
films. The final film obtained will be improved in the mechanical properties, and
deterrent features.
