Researchers at Singapore’s Nanyang Technological University (NTU) have found a way to turn durian husks into biodegradable packaging materials.
Most fruits contain large amounts of pectin. Pectin is a natural part of the human diet. While pectin can be used to make jam hold its structure, or in some medical adhesives, Professor William Chen, director of NTU’s food science and technology program, has found a way to extract pectin from durian husks and turn it into biodegradable packaging materials.
To do so, the husks are cut, then ground and shredded to produce a cellulose powder. This is then used to create sheets of the biodegradable material. The material is shiny and slightly cloudy – and can be degraded within a month if it is put in the soil. If required, the material’s coloring can be changed by introducing color into the cellulose shreds.
According to lifestyle.inquirer.net Professor Chen and his team are in talks with several food and beverage companies to work on commercializing the material.
