“…The water solubility of films based on cassava starch and carnauba wax, developed by Chiumarelli and Hubinger (2012) ranged from 27.86 to 51.09 % which, according to the authors, were suitable for applications on fresh-cut fruits. This way, the films B2% and B5% with respect to solubility have favorable properties for possible applications with fresh-cut fruits.…”

Biodegradable and active packaging based on cassava starch incorporated bixin nanocapsules with different concentrations were developed. The physical, mechanical, barrier properties and antioxidant activity of the active packaging were studieds. The films incorporated with bixin nanocapsules were found to be homogeneous and thermally stable. Films with higher concentrations of bixin nanocapsules exhibited a significant decrease in tensile strength, water solubility and increase in elongation at break and water vapour permeability, well as, significant improvement in protection against UV and visible light. The films were used to pack sunflower oil under accelerated oxidation conditions (65 % RH/35°C). Sunflower oil packaged in films with bixin exhibited lower oxidation rates, thus maintaining its freshness according to Codex Alimentarius guidelines (\10 mEq kg -1 ). Films containing bixin nanocapsules are very promising materials for use as packaging with antioxidant properties for maintaining food safety and extending the shelf life.

“…The glycerol content of waste acted as a plasticizer and may have reduced the interactions between polymer chains, thereby increasing film flexibility [24] . Glycerol can be used in biodegradable films to increase their flexibility and elongation values, however reduce the values of tensile strength [25] . The studied films presented high percent elongation at break, providing films with higher flexibility and that take a longer time to break.…”

“…Table 2, the solubility in water for gelatin films was approximately 45%. The high glycerol content of nutraceutical capsule waste interacts with the film matrix by increasing the space between the chains, facilitating water migration into the film and, consequently, increasing solubility [25] . Nur Hanani et al [30] , found similar values of 40% for films prepared with fish gelatin.…”

“…Lipids used in coating formulation for preserving minimally processed products are stearic acid, palmitic acid and certain vegetable oils such as soybean and sunflower oil. Waxes such as carnauba, candelilla and bee are also used, showing better gas and moisture barrier properties than coatings containing only fatty acids 5 . In the studies of Chiumarelli and Hubinger 5 , when they used cassava starch and carnauba wax edible coatings to preserve fresh-cut apples verified that there was an improvement in their water vapor permeability, solubility, among other analyzes.…”

Effect of the Addition of Carnauba Wax on Physicochemical Properties of Chitosan Films

et al. 2017

Films and edible coatings of natural polymers have been proposed as an attractive alternative for conventional plastic packaging because of their excellent biodegradability and biocompatibility. However, natural polymers, like chitosan, are hydrophilic and present poor water barrier properties. The addition of wax or other hydrophobic substances decreases water permeability of natural polymers but can increases their opacity.The objective of this work was to produce biofilms based on chitosan and different concentrations of carnauba wax and analyze their optical and barrier properties. The films were obtained by dissolving chitosan in acetic acid. Carnauba wax was incorporated into filmforming solutions at0, 15, 30, 40 and 50% (w/w). The opacity increased with higher concentrations of wax, the film with 50% of wax showed the highest value with an increase of 10.5% compared to the control film. The water vapor permeability decreased from 2.73 g.mm/kPa.m 2 .h (0% of wax) to 0.77 g.mm/h.kPa.m 2 (40% of wax). The solubility decreased to about 60% over the control films, and the contact angle increased from 53º to 83º, in film with 0 and 50% of wax, respectively.
