“…These results reflected a significant increase in the extent of the crystalline cellulose due to a more ordered and compact crystal structure in MCC. Published CI values for MCC from different agricultural sources other than cotton were in the 60%-70% range [1,[3][4][5], which was in agreement with the CI value obtained in this work.…”

“…It has been known that MCC properties might vary according to the crystallinity, humidity content, surface area, porosity, and molecular weight of the cellulosic source [1]. A number of cellulosic sources have also been explored in the last twenty years such as bagasse [2,3], flax and hemp [4,5], soybean [6] and pineapple [7], among others. Pineapple (Ananas comosus) is a major export product in Costa Rica with an annual volume of 2.5 million metric tons according to statistics of the Food and Agricultural Organization (FAO).…”

Poly(lactic acid) (PLA) composite films reinforced with microcrystalline cellulose (MCC) extracted from pineapple leaf fibers (PALF) were prepared by a solution casting procedure. In an attempt to improve the interaction between PLA and cellulose, two approaches were adopted; first, poly(ethylene glycol) (PEG) was used as a surfactant, and second, the cellulosic fibers were pre-treated using tert-butanol (TBA). Lignocellulosic and cellulosic substrates were characterized using Fourier transform infrared (FTIR), wide-angle X-ray scattering (WAXS), and thermogravimetrical analysis (TGA). MCC from PALF showed good thermal stability, left few residues after decomposing, and exhibited high crystallinity index. Mechanical, thermal and thermomechanical properties of the PLA composites were also evaluated. Multiple PLA endotherms were observed in composites with TBA-treated MCC due to crystal nucleation effects. The ultimate tensile strain values for all composites were lower than that of the pristine PLA. However, 4 wt. % MCC content provided balanced engineering properties in terms of static and dynamic tensile properties.

“…On the basis of this finding, sample Raman crystallinities were corrected for hemicellulose contribution using the correlation developed. Hemicellulose content of the samples was taken from Table and from the literature. − Corrected values are listed in Table (column 8). These data are believed to be the most accurate measures of cellulose crystallinity using Raman spectroscopy because the originally estimated crystallinities are now corrected for both the syringyl lignin contribution, needed for hardwoods and most agricultural residues/fibers, and the effect of hemicellulose.…”

Of the recently developed univariate and multivariate near-IR FT-Raman methods for estimating cellulose crystallinity, the former method was applied to a variety of lignocelluloses: softwoods, hardwoods, wood pulps, and agricultural residues/fibers. The effect of autofluorescence on the crystallinity estimation was minimized by solvent extraction or chemical treatment or both. Additionally, when the roles of lignin and hemicellulose in the Raman crystallinity assessment were investigated, it was found that syringyl lignin containing lignocelluloses generated somewhat higher crystallinity, whereas the presence of hemicellulose reduced the crystallinity. Overall, when autofluorescence was minimized and corrections made for hemicellulose and syringyl lignin contributions, the univariate Raman method performed well and estimated cellulose crystallinity accurately. Moreover, when the Raman and Segal-WAXS methods were compared, we observed that in the absence of significant fluorescence, the Raman method was influenced mostly by hemicellulose and syringyl lignin, whereas the Segal-WAXS was affected by various types of lignin and hemicellulose. It was concluded that the near-IR FT-Raman method with corrections for influences of syringyl lignin and hemicellulose can be used to correctly estimate cellulose crystallinity.

“…MCC is obtained on an industrial scale through the hydrolysis of wood cellulose and of cotton cellulose using dilute mineral acids. The preparation of MCC from wheat and cereal straws (Alemdar & Sain, 2008;Jain, Dixit, & Varma, 1983), jute (Abdullah, 1991), soybean husk (Nelson, Edgardo, & Ana, 2000), flax fibres and flax straw (Bochek, Shevchuk, & Lavrentev, 2003), sugar cane bagasse (Bhattacharya, Grminario, & Winter, 2008), mulberry barks (Li et al, 2009) and peel of pear fruits (Habibi, Mahrouz, & Vignon, 2009) has been studied.…”
