Potensi Limbah Sisik Ikan Sebagai Kitosan dalam Pembuatan Bioplastik

Abstract

<p><strong>Bioplastics are environmentally friendly plastics derived from natural materials. Bioplastics are easier to decompose when compared to commercial plastics. Bioplastics are generally made from starch contained in plants. But the use of starch as a base material has the disadvantage of producing bioplastics that are not waterproof. Therefore, it is necessary to add chitosan to improve bioplastic characteristics. Chitosan usually comes from the shell of crustacean animals, but it turns out that in fish scales waste, also contains chitosan. Fish scales are a by-product of the process of fish processing. Fish scales are only discarded and not utilized so that they become waste that can pollute the environment. Fish scales have a chitin content that can process into chitosan, which can be useful as an additional ingredient in the manufacture of bioplastics. This review aims to find out the potential of fish scales waste as chitosan in the manufacture of bioplastics. Based on the results of previous research, fish scales have a chitosan content that can use as an additional ingredient in the manufacture of bioplastics. Fish scale chitosan can form bioplastic film with characteristic brownish-yellow film. The addition of fish scale chitosan is also able to improve the water resistance of bioplastic film. Based on the results of the review can be concluded bring fish scales to have the potential as chitosan that can use in the manufacture of bioplastic.</strong></p><p><strong>Keywords –</strong> <em>Bioplastic, Chitosan, Fish Scales.</em></p><p> </p>

Exploring the Transformation of Food Waste into Bioplastic Materials: A Review

“…Chitosan (Fig. 12), a biopolymer derived from the deacetylation process of chitin, is typically extracted from crustacean shells, such as those of crabs and shrimps, as well as from the cuticles of insects, fungi, and even fish scales [23].…”

“…The hydrophobic, non-toxic, and biodegradable properties of chitosan contribute to the development of robust bioplastics with heightened water resistance. The inclusion of chitosan also augments the number of hydrogen bonds within the bioplastics, providing additional support to their structural integrity [23].…”
