Abstract |
Plastics have prohibited its use in certain applications because of environmental issues. Therefore, a more eco-friendly option is needed for food packaging and containers. This study uses the waste of orange peel to create a biopolymer that can be used for these purposes. Orange peel of 100 and 250 micrometers, starch, from two sources: corn and potato (7.5%), glycerol (6.0%) and water (71.5%) are the main materials used in these formulations. In addition, two technological procedures were evaluated: the cooling gel method (room temperatures, refrigeration (4 degrees C) freezing (-18 degrees C) and the way in which water was eliminated: solar, oven (120 degrees C) and dehydration (42 degrees C). In order to obtain the best results, 54 experiments were carried out in triplicate and the parameters were evaluated: flexibility, porosity, water absorption, fracture force and biodegradability. Best results were obtained when utilizing orange powder of 250 micrometers, the bioplastic showed a better texture than the one utilizing powder of 100 micrometers. Different ratios of corn and potato starch hardly reveal any differences in the final biopolymer properties, however, from an economical point of view; corn starch is the best option. The best cooling methods of the gel are both refrigeration and room temperature; whereas the latter implies less energetic consumption and therefore it is suggested. The biopolymer made with 100% corn starch and using solar drying showed to be the most flexible one, as well presented less porosity, which is translated into less water absorption; exhibiting a biodegradability of 63% in 21 days. In future studies. |
