Tara gum can be a substitute for synthetic plastics: Study
Amidst the quest to find sustainable alternatives to plastics, a team of researchers from Chung-Ang University in South Korea has come up with a discovery. It was found that tara gum, a natural, water-soluble substance, is a sustainable and biodegradable substitute for synthetic plastic in applications like packaging, edible films, and coatings. The study emphasized tara gum's ability to lessen the environmental effect.
Understanding tara gum
According to the team, tara gum, derived from the seeds of the tara tree (Caesalpinia spinosa) contains polysaccharides (complex carbohydrates), including the widely used "galactomannan," which is employed in coatings, edible films, and used as a stabilizer and thickener. The study states that the biocompatibility, biodegradability, and safety of tara gum can make it valuable in industries like food and drug delivery.
About the study
The team presents a systematic and detailed overview of various advancements in tara gum research. They describe methods for the extraction, isolation, and characterization of tara gum polysaccharides. Additionally, they examined the toxicology and rheological (deformation) behavior of tara gum, along with its behavior in the presence of other polysaccharides. The study was published in the journal Carbohydrate Polymers.
How tara gum helps in the food and drug industry
The paper also delves into the applications of tara gum in the food industry. These include the use in biopolymer packaging, monitoring seafood and milk spoilage, acting as a gelation agent, providing short-term protection of food from oxidation, and safeguarding fatty foods. In the pharmaceutical industry, tara gum can be used in antibacterial hydrogel development, iron delivery in people and controlled release of drugs.
First study on its applications in food/drug industry: Research lead
"Various researchers have explored the wide range of applications for its various modified forms. However, this is the first review article on recent advancements in tara gum and its modified materials, and their potential role in food and drug delivery," says research team lead Professor Sangkil Lee from Chung-Ang University. As per the team, the study could lead to further research on tara gum.
