PENGARUH PENAMBAHAN EKSTRAK DAUN BAMBU (ANTIOXIDANT OF BAMBOO LEAVES) TERHADAP FILM KEMASAN AKTIF BERBAHAN KITOSAN
The current function of packaging, apart from protecting food products, is also required to have the ability to maintain quality and extend the shelf life of packaged food .One of the environmentally friendly plastic raw material alternatives that has been extensively researched is chitosan. Plastic packaging film can also be made by adding active substances that have specific functions, such as antimicrobial and antioxidant properties. This study aims to obtain active packaging in the form of plastic packaging film from chitosan with additional ingredients in the form of bamboo leaf extract and to determine the effect of the concentration of bamboo leaf extract and chitosan on the physical and chemical characteristics of the resulting film packaging. This study was conducted with variations in chitosan concentration of 2%, 3%, and 4% and Antioxidant of Bamboo Leaves (AOB) 0.4%; 0.5%; and 0.6% using the casting method, which involves dissolving the materials, then heating and drying them using molds. The tests conducted included water resistance, tensile strength and elongation, FTIR, biodegradation, antioxidant, and antimicrobial tests. The results show that an increase in AOB concentration can increase tensile strength and compact the film structure from 4.04 MPa to 5.06 MPa, as well as increase the rate of biodegradation and have a positive effect on antioxidant activity with a value of 17223.23 mg/kg. The best results in the experiments conducted were achieved with a 2% chitosan and 0.4% AOB variation, as it produced the most compact film structure, making it mechanically strong, having good biodegradability and flexibility, as well as sufficient antioxidant activity.
