Effect of Mung Bean Protein Coating Incorporated with Cinnamon Bark Essential Oil on Kraft Paper.

In this study, two types of coatings were prepared, 3% w/v of mung bean protein and mung bean protein incorporated with 3% v/v of cinnamon bark essential oil. Incorporating cinnamon bark essential oil with mung bean protein for the coat on kraft paper does not significantly affect the basis weight and thickness. The surface characteristics of both coated kraft paper are no different, which were studied by using SEM. The result from infrared transformed spectroscopy (FT-IR) found that both coatings affect the cellulose bonds in the kraft paper, and cinnamon bark essential oil slightly affects protein bonds. Analysis of volatile compounds from kraft paper was coated with mung bean protein incorporated with cinnamon bark essential oil made by GCMS found 78.60% cinnamaldehyde compound of all volatile compounds. All results confirm that mung bean protein with cinnamon bark essential oil can coat on kraft paper. Permeability, mechanical properties, and consumer acceptance can be further studied for the development of the packaging.
