Data supporting the production of dietary fibers from sugarcane bagasse and sugarcane tops using microwave - assisted alkaline treatments

Abstract

The treatment of agroindustrial residues is an alternative to waste management and obtain products with added value. In this article, we describe the confocal microscopy images, the microbiological data, policosanol content and color measurement linked to the paper “production of dietary fibers from sugarcane bagasse and sugarcane tops using microwave - assisted alkaline treatments”. The data contain photographs after elaboration of noodles-type pasta and chapatti-type fermented bread; the confocal laser scanning micrographs, before and after including sugarcane bagasse and sugarcane tops fibers in foods. Microbiological analyses of total coliforms, molds and yeasts, and aerobic mesophiles were also presented according to Mexican Standard NOM- 247-SSA1-2008 which confirmed that the food is safe for human consumption. The data provided in this article have not been previously published and are available to enable critical or extended analyses.

Effects of mixed enzymolysis alone or combined with acetylation or carboxymethylation on the role of jujube kernel fibre as a biosorbent for wastewater treatment

“…Cellulase, hemicellulase, and laccase can cause a degradation of cellulose, hemicellulose, and lignin, 33 resulting in a decreased insoluble bre content and increased soluble bre content. Furthermore, the soluble bre contents of JKF, JKF-EC, and JKF-EA (13.64-18.32 g 100 g −1 ) were much higher than those of rice bran bre (3.03 g 100 g −1 ), 7 coconut mesocarp bre (4.01 g 100 g −1 ), 27 soybean hulls bre (1.76 g 100 g −1 ), 9 and sugarcane bagasse bre (3.12 g 100 g −1 ), 6 highlighting their relatively high hydration properties.…”

“…30 An obvious red-shi occurred for the peak located at the wavenumber of around 3300 cm −1 in the spectra of JKF-E, JKF-EA, and JKF-EH, suggesting that mixed enzymolysis, and mixed enzymolysis assisted with acetylation or carboxymethylation changed the hydrogen bonds of JKF. 35 Moreover, the peaks at wavenumbers of 1760 and 1046, 1500 cm −1 (indicative of the asymmetric bend of acetyl groups, C-O-C, and -C]O, respectively) in the spectrum of JKF separately appeared at 1762, 1037, and 1508 cm −1 in the spectrum of JKE-SGEA, 6 demonstrating that acyl ester groups had been introduced into the JKF molecules aer acetylation. Additionally, a new peak appeared compared with the spectrum of JKF, with the spectrum of JKF-EC showing this new peak at around 964 cm −1 , which was attributed to the introduction of the carboxymethyl group aer carboxymethylation.…”

“…Among these, the use of natural biopolymers, especially bre, starch, and chitosan, as adsorbents to treat wastewater is popular for their high availability, low cost, and renewability. 4,6 Compared to active carbon and starch, adsorbents derived from plant bres have remarkable advantages, including availability, low cost, reasonable strength and stiffness, and low density. 5 In recent decades, the adsorption properties of heavy metals, phytonutrients, oil and other toxic substances in wastewater on various agro-based waste bres, such as rice bran, coconut shell, millet bran, and sugarcane bagasse, have been studied.…”

“…5 In recent decades, the adsorption properties of heavy metals, phytonutrients, oil and other toxic substances in wastewater on various agro-based waste bres, such as rice bran, coconut shell, millet bran, and sugarcane bagasse, have been studied. [6][7][8] Although insoluble bre also plays a role in the wastewater treatment ability of bre adsorbents, a large number of studies have shown that the wastewater treatment ability of bre is mainly dependent on surface microstructure, soluble bre content, hydrophobicity and hydrophilicity. 1,5 However, many natural bre adsorbents show relatively poor adsorption capacities for toxic and harmful substances in wastewater due to their low hydration properties, small specic surface area, and few functional groups.…”

“…4 Thus, various physical, biological, and chemical modications have been explored to improve the adsorption capacity of bres. 6,9 Among these methods, enzyme hydrolysis is a biological modication for increasing the hydration and adsorption properties of bres, with the advantages of environmental friendliness, low-energy consumption, selectivity, and mild operation. [10][11][12] Cellulase and lignin enzyme hydrolysis can cause a rupture of the glycoside bonds of bres, exposing more hydrophilic groups and increasing the contact area of bres with adsorbed substances.…”
