Abstract
Abstract This work aimed to develop biodegradable films utilizing a new source of gelatin derived from the nutraceutical capsule manufacture waste of coconut with safflower oil, coconut oil and safflower oil. The mechanical, physicochemical, barrier, optical, biodegradation, thermal and morphological properties were evaluated. All films showed low water vapor permeability, intermediate water solubility and high elongation at break. In addition, the films exhibited excellent barrier ability to ultraviolet light. After 15 days of soil burial degradation, the films lost over 68% of initial weight. Scanning electron microscopy showed an appearance free of pores, cracks or bubbles. Furthermore the films showed similar characteristics independent of the waste utilized. The results demonstrated that all the biodegradable films prepared presented appropriate characteristics to be used as substitute to synthetic packaging.
Highlights
The development of biodegradable film is an nutraceutical capsules can be considered a new source of environmentally friendly technology that would permit a protein and has a high glycerol content naturally present in reduction in the impact and costs associated with polymers its composition
The results demonstrated that all the biodegradable films prepared presented appropriate characteristics to be used as substitute to synthetic packaging
Numerous substances related to the food production process are suitable for separation and reuse[3], such as chitosan and soy by-products from soy oil industry[4]
Summary
The development of biodegradable film is an nutraceutical capsules can be considered a new source of environmentally friendly technology that would permit a protein and has a high glycerol content naturally present in reduction in the impact and costs associated with polymers its composition. The glycerol provides better mechanical from non-renewable sources. Highest plasticizing effect on the mechanical properties, One of the alternatives for the biodegradable films production is the use of new materials. Polymers obtained from renewable resources or valorization of industrial wastes and by-products are considered a good alternative to reduce environmental impacts and costs[2]. The wastes may contain many substances of high value and if appropriate technology is employed, these materials can be converted into commercial products or raw materials for secondary processes. Numerous substances related to the food production process are suitable for separation and reuse[3], such as chitosan (derived from marine wastes) and soy by-products from soy oil industry[4]
