Thivya P, Gururaj PN, Reddy NBP, Rajam R. Recent advances in protein-polysaccharide based biocomposites and their potential applications in food packaging: A review. Int J Biol Macromol 2024; 268:131757. [PMID: 38657934 DOI: 10.1016/j.ijbiomac.2024.131757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 04/09/2024] [Accepted: 04/20/2024] [Indexed: 04/26/2024]
Abstract
This review addresses the current trend of replacing petroleum-based polymers in food packaging with bio-based alternatives, specifically focusing on proteins and polysaccharides. While these biopolymers exhibit excellent film-forming properties and are abundant in nature, their individual use in packaging lacks ideal plastic-like characteristics, especially in terms of mechanical and barrier properties. A recent solution involves the formulation of biocomposites through the reinforcement of one biopolymer with another (e.g., protein with a polysaccharide), significantly enhancing the physical, mechanical, and barrier properties of packaging materials. The review concentrates on the integration of proteins and polysaccharides in biocomposite materials, emphasizing their potential applications in active and intelligent food packaging systems. It covers sources, manufacturing methods, interaction mechanisms, recent developments, perspectives, and opportunities. The exploration extends to practical implementations of these biocomposites in enhancing food quality, safety, and shelf life-a green technological approach contributing to the reduction of food waste and loss.

J Control Release 2022; 350:748-760. [PMID: 36030990 DOI: 10.1016/j.jconrel.2022.08.039] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 08/20/2022] [Accepted: 08/21/2022] [Indexed: 11/28/2022]
Abstract
In the past decades, polyurethane has emerged as a new material that has been widely developed and applied in coated controlled release fertilizers (CRFs). Particularly in recent years, the excessive consumption of petroleum resources and increasing demand for sustainable development have resulted in considerable interest in bio-based polyurethane coated controlled-release fertilizers. This review article focuses on the application and progress of environmentally friendly bio-based materials in the polyurethane-coated CRF industry. We also explore prospects for the green and sustainable development of coated CRFs. Using animal and plant oils, starch, lignin, and cellulose as raw materials, polyols can be produced by physical, chemical, and biological means to replace petroleum-based materials and polyurethane film coating for CRFs can be prepared. Various modifications can also improve the hydrophobicity and degradability of polyurethane film. A growing body of research on bio-based polyurethane has revealed its great potential in the production and application of coated CRFs. The purpose of this review is to highlight the practicality of bio-based materials in the application of polyurethane-coated CRFs and to clarify their current limitations.
