Packaging is part the end of a production process food or other products. Packaging useful to increase the consumer revenue, also reduce degrees damage during the transport of products. Packaging is also one of a way to protect or adding power savings food products and non-food. Packaging is not only aimed to preserve, but also be a means of supporting in transportation, distribution, and forms an important part of an effort to overcome competition product marketing. Packaging industry mostly dominated by plastic materials and it has resulted in an increase of plastic waste which directly destroying the environment. Such materials cannot be degrading easily, expensive for the recycling and causes contamination to food stuffs. One of the alternative …show more content…

The solution was mechanically stirred at 800 rpm for 1 h for complete dissolution. Glycerol 3% (w/w) was added in pectin solution and stirring was continued for 5 minutes. Finally, the suspension was poured onto a series of petri dishes and dried in a tray dryer at 40°C for 24hr. The composite films were prepared by mixing pomelo peel pectin solution (5g/100ml) and chicken feather protein solution (5g/100ml) in different proportions as shown in Table 1. All dispersions were prepared under constant magnetic stirring at room temperature for 1 h. These film forming dispersions was poured into petri dishesand dried in a tray dryer at 40°C for 24h. Finally, the films were removed from the casting surface and stored for analyses. The schematic diagram for composite film development is shown in Fig. …show more content…

The five different films produced varied in their color mostly due to the different proportions of pomelo peel pectin and chicken feather protein. Pomelo peel pectin left slightly amber color in the films. Hunter color data revealed that film (F5) had the highest L* value (51.39) and lowest for the F1 film (43.37). It has been seen that, as the proportion of PPP increases in CFP, the lightness of films were increased remarkably (Table 2).It means the concentration of pectin in the final films was responsible for the difference in the colour of the films. Similarly, redness (a* value) value were increased from 0.05 for F1 to 0.22 for F5 with increase in pectin content and yellowness (b* value) value of films were decreased with addition of pectin.

3.2.5. Transparency of film F2 was better at wavelengths between 250 to 850 nm than other composite film (Table 2). However, it has been seen that as the pectin content increased the transparency also increased. It may be due to the presence of complex polymer matrix of composite film. Transparency most of the time depends on the polymer structure and their bonding in composite film. Transparency properties are correlates with the light transmittance properties of the film (Mardare, Tasca, Delibas, & Rusu,
