Development of Antibacterial Nanocomposite: Whey Protein-Gelatin-Nanoclay Films with Orange Peel Extract and Tripolyphosphate as Potential Food Packaging

Table 1

Different concentrations of components for preparing films and their symbols.

Film symbol	Nanoclay (%w/w WPI)	OPE (%w/v)	TPP (%w/v)
WG	0	0	0
WGN5	5	0	0
WGN5-7	5	7	0
WGN5-14	5	14	0
WGN5-21	5	21	0
WGN5-21-TPP	5	21	0.75

a WG demonstrates the WPI-gelatin film sample containing 5 % (w/v) WPI and 2% (w/v) of gelatin.
b demonstrates WG films added by 5 (%w/w WPI) of nanoclay
c, d and e demonstrate WGN5 films added by 7, 14 and 21 (%w/v) of orange peel extract respectively.
f demonstrates WGN5-21 films added by 0.75 (%w/v) of Sodium triphosphate.
