- Description
- Recently, edible films and coatings have received more attention instead of plastic packaging. Pectin prepared from gac pulp, a waste generated from gac oil production, was used to prepare edible films combined with seaweed hydrocolloids. This study aimed to investigate the impact of sodium alginate (SA), kappa-carrageenan (KC), and gac pulp pectin (GPP) on the physical, barrier, and mechanical properties of the resultant films. The optimum formula with the best characteristics was identified using Response Surface Methodology (RSM). Results revealed that most of the film properties were significantly influenced by seaweed hydrocolloids, while GPP significantly affected color properties. Besides, the interaction between GPP and seaweed hydrocolloids affected the water vapor permeability and mechanical properties. The optimum formula was SA of 1.28% w/v, KC of 0.58% w/v, and GPP of 0.25% w/v. The result suggests that this formula has the potential as an edible film for further applications in foods.
