Eucalyptus sp. is the most important planted crop for production of chemical pulp. This pulp mostly bleached with chlorine dioxide, which produces hypochlorous acid in situ when reacting lignin. However, applying hypochlorus directly not practiced, even though it contributes significantly to bleaching reactions. Therefore, this article presents as main oxygen delignified kraft The results showe...
Comparative study on organosolv pulping method have been done by using various mixtures of water and organic solvents as delignifying agents including ethylene glycol-water mixtures, ethanol-water mixtures and acetic acid-water mixtures to extract cellulose from agricultural crop biomass (Oil palm empty-fruit bunches-OPFB). The yield of organosolv pulping with ethylene glycol-water mixture, eth...
Antioxidant capacities and polyphenolic contents of two mango cultivars from northern Chile, one of them endemic of an oasis in the Atacama Desert, were compared for the first time. Twenty one phenolic compounds were detected in peel and pulp of mango fruits varieties Pica and Tommy Atkins by HPLC-PDA-MS and tentatively characterized. Eighteen compounds were present in Pica pulp (ppu), 13 in Pi...
Betalains have high nutritional value and bioactivities. Red pulp pitaya (Hylocereus polyrhizus) is the only fruit containing abundant betalains for consumer. However, no information is available about genes involved in betalain biosynthesis in H. polyrhizus. Herein, two cDNA libraries of pitaya pulps with two different coloration stages (white and red pulp stages) of Guanhuahong (H. polyrhizus...
Pectinase (Pectin methyl esterase) produced by Aspergillus niger in solid state fermentation of apple pomace using the optimized conditions was partially purified by (NH4)2SO4 fractionation (20-80% concentration). The purified enzyme was found to be stable up to 60 days. It remained heat stable up to 50oC but completely inactivated at 90oC. The partially purified enzyme showed highest activity ...
