Researchers from the Indian Institute of Technology, Kharagpur, explored the use of cellulose nanocrystals extracted from discarded cucumber peels to create biodegradable food-wrapping films. These films are biocompatible, lightweight, and can withstand high temperatures. The study revealed that cucumber peels have higher cellulose content than other fruit peels, making them ideal for producing nanofillers. The nanocrystals also have potential applications in drug delivery systems, sutures, and optically transparent films.
The process used in this project involves extracting cellulose from dried and powdered cucumber peels. The cellulose is then converted into cellulose nanocrystals using specific chemicals. These nanocrystals are characterized by a high surface-to-volume ratio, making them ideal for various applications. The resulting nanocrystals are used to create biodegradable food-wrapping films and other products.
