Physical Properties of Carboxymethyl Cellulose Reinforced-Sucrose Plasticised Thermoplastic Mango Starch Biofilms
AI summary Read the abstract
This study developed biodegradable biofilms made from mango starch reinforced with carboxymethyl cellulose and sucrose as a plasticizer. Researchers characterized the physical properties of these sustainable packaging materials as alternatives to conventional plastic food packaging.
Attempt to save the planet from numerous environmental challenges has been an on-going activity for many decades, through the use of sustainable materials and processes. These have necessitated researches in materials science driven by sustainable chemical approach to derive sustainable materials that do not depend on fossil resources for industrial feedstock, and these materials do not have a negative outcome on the environment. This study investigated the physical and intermolecular interaction of Mango starch derived bioplastic plasticised with sucrose, and reinforced with carboxymethyl cellulose (CMC). Water uptake (WU) were observed to decrease significantly as the molar concentration of HCl or sucrose increases independently, and increase in WU was observation when CMC was increased (p ≤ 0.05). Increasing the molar concentration of HCl or the percentage amount of sucrose as plasticiser has no effect on the oil-uptake (OU), while increasing the percentage of CMC resulted to a decrease, which shows no effect as the CMC amount increases (p > 0.05). Vapour absorption index (VAI) showed a similar trend to WU but significantly, higher outcomes were observed (p ≤ 0.05). The FTIR results also indicate that a physical interaction has occurred between the blends increase in sucrose showed a change in the FTIR peaks especially in the broader peaks observed in the O-H regions of 3500-3200 cm-1 compared to unplasticized native mango starch.

Influence of the microstructure in the biodegradability process of eco‐friendly materials based on polylactic acid and mango seed for food packaging to minimize microplastic generation
AI summary Read the abstract
Researchers developed biocomposite food packaging materials by loading mango seed components (kernel and integument) into a polylactic acid (PLA) matrix via casting, characterizing the resulting materials for mechanical, thermal, and biodegradation properties. They found that the mango-PLA composites showed improved performance characteristics and biodegradability potential compared to pure PLA, with implications for reducing microplastic generation from food packaging disposal.
