The coating composition is chosen as a function of the desired application, and this composition is very important to determine the functional properties of the film in the product to be coated. On the other hand, the use of edible coatings is a promising technology to preserve the quality of whole or fresh-cut minimally processed fruits or vegetables. Edible films and coatings are traditionally used to improve the appearance and the preservation of food products. In addition, edible films, when used as protective coatings, can control mass transfer of substances (i.e., water vapor, oxygen, carbon dioxide, lipid, flavor, and/or aroma) with a resulting increase in quality and shelf life of food products. ![]() This approach may offer opportunities that would benefit both consumers and manufacturers by providing environmentally friendly packaging and less waste from the packaging industry. The presence of Tween-80 resulted in better dispersion of lipid particles in film-forming solutions and lower water solubility, lightness, film opacity, and water vapor permeability, whereas the total color differences (∆E) were significantly larger and the improvement in mechanical properties was also achieved.ĭevelopment of edible films for application as packaging materials is a subject of great interest due to the partial replacement of synthetic polymers. Films containing candelilla wax exhibited more regular lipid reorganization, which resulted in better water vapor barrier efficacy and mechanical resistance in comparison to control films. A different internal arrangement was observed as a function of the film composition with both layered and incorporated film structure. Scanning electron microscopy showed heterogeneous structure of emulsion films with regular distribution of lipid particles. The results showed that the incorporation of waxes increased film opacity, total color differences (∆E), and mechanical resistance and reduced film lightness, water vapor permeability (WVP), and elongation at break. Glycerol and Tween-80 were used as the plasticizer and the emulsifier, respectively. Tracks visits of LinkedIn useres on the website.The aim of this study was to evaluate the effects of candelilla (CAN) or carnauba wax (CAR) incorporation on functional properties of edible sodium caseinate (CAS) films.

In addition, the wax gives the food a beautiful sheen - as is the case with Smarties, for example.Ĭarnauba wax is used in the food industry primarily as a separating and coating agent in the following products:Ĭarnauba is indigestible, but since it is only used in very small quantities, it does not pose a problem for the organism and is considered to be well tolerated.Ĭontains campaign related information for the user. ![]() In this process, sweets in particular are coated with a solid layer to protect the coated food from external influences such as moisture, heat or oxygen. Such a coating by carnauba can also be helpful in coating. In addition, the wax has the advantage as a coating agent that gummy animals or chewing gum do not stick together.Ĭarnauba wax can also be used as a protective coating for citrus fruits to preserve them and make them last longer. On the packaging of the corresponding foodstuffs, the wax is usually labelled with the abbreviation E903.Ĭarnauba wax is a popular alternative to beeswax, so that it is used in gummy bears, for example, to make them palatable for vegans. The purely plant-based carnauba wax is harmless to the organism and the environment, which is why it is a component of numerous foods.
