Valorization of Seafood Waste for Food Packaging Development

Area of Science:

• Materials Science
• Food Science
• Environmental Science

Background:

• Petroleum-based plastics cause environmental pollution and health risks due to slow degradation.
• Renewable biopolymers from seafood waste (chitin, chitosan, gelatins, alginate) are sustainable alternatives for food packaging.
• Biopolymer films often exhibit inferior mechanical and barrier properties compared to synthetic polymers.

Purpose of the Study:

• To review biopolymers derived from seafood waste for food packaging applications.
• To discuss their chemical structure, extraction, and use as reinforcement or base materials.
• To guide research towards successful replacement and commercialization of traditional plastics.

Main Methods:

• Comprehensive literature review of seafood waste-derived biopolymers.
• Analysis of chemical structures, extraction techniques, and material characteristics.
• Examination of advancements in improving film properties and antimicrobial activities.

Main Results:

• Seafood waste biopolymers show potential for food packaging, offering biodegradability and non-toxicity.
• Recent advancements have improved thermal durability, mechanical strength, and barrier properties of these biopolymer films.
• Antimicrobial activities of these biopolymers are also noted, enhancing food preservation.

Conclusions:

• Biopolymers from seafood waste are promising for developing sustainable food packaging.
• Further research and development are needed to overcome current limitations and achieve commercial viability.
• These materials offer a viable path to replace conventional plastics, reducing environmental impact.
