Isolation and characterization of cellulose nanofibers from cassava root bagasse and peelings

Abstract: This work aimed to obtain and characterize nanofibers from cassava bagasse and peelings, which are waste originating from cassava starch extraction. To isolate the nanofibers, a combination of pre-treatments (alkaline treatment, Q-chelating treatment, bleaching), acid hydrolysis, and a final ultrasonic disintegration step were used. Acidic hydrolysis was conducted at a constant temperature of 60°C; the acid concentration (30, 40, and 50%) and the treatment time (30, 60, and 90min) were varied. The nanofibers w… Show more

“…5) images confirmed the presence of CNFs in the six aqueous suspensions and indicated that the CNFs had a web-like network structure with long entangled cellulosic filaments. Leite et al (2017) noticed CNFs with similar characteristics when they isolated nanofibers from cassava root bagasse and peelings and characterized them by the AFM and TEM techniques. The CNFs obtained in this work had average diameter ranging from 2.89 to 4.65 nm (Table 1), showing that the chemical and mechanical treatments effectively isolated cellulose fibers at the nanoscale.…”

“…Agricultural waste has become an attractive nanofiber source: this waste consists mainly of plant fibers that are rich in cellulose, the main component of plant cell walls (Lavoine, Desloges, Dufresne, & Bras, 2012). Researchers have isolated cellulose nanofibers (CNFs) from the peels of fruits and vegetables such as cassava (Leite, Zanon, & Menegalli, 2017), tomato (Jiang & Hsieh, 2015), and potato (Chen, Lawton, Thompson, & Liu, 2012).…”

“…However, recent studies have shown that various plant-based waste materials such as peel, husk and The most commercially exploited sources of cellulose are wood pulp and cotton fibers [41]. However, recent studies have shown that various plant-based waste materials such as peel, husk and shell, and sugar cane bagasse present suitable sources of cellulose, which is important from both economic and ecological point of view [42][43][44].…”

“…Since the beginning of 1980s, as a new form of cellulose-based material, CNF, was first developed by researchers in the United States (Turbak, Snyder, & Sandberg, 1983), the enthusiasm for CNF has been increasing day by day. CNF is a kind of nanofibers composed of expanded and colloid cellulose microfibrils aggregates, which can be obtained from various plant cellulosic sources by mechanical, chemical or enzymatic methods (Leite, Zanon, & Menegalli, 2017;Nechyporchuk, Belgacem, & Bras, 2016;Tibolla, Pelissari, Rodrigues, & Menegalli, 2017).…”
