Procedure to Reduce Sulphite in Wine with Anion-exchange Resin
HORÁK, M., HÍC, P., TOMÁNKOVÁ, E., BALÍK, J.: Procedure to reduce sulphite in wine with anion-exchange resin. Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 8, pp. 79–86 The aim of this experiment was to eliminate SO2 ions present in wine using the anion-exchanger resins. To compare the eff ectiveness, 2 following strongly basic anion-exchange resin were used. When activated, the sod...
متن کاملModification of Spruce Sulphite Pulp by Cellulase Treatment
Enzymatic treatment of different sulphite pulps with cellulases has been studied in this work. Endoglucanases were shown to beneficially alter the properties of both paper-grade and dissolving-grade pulps. In the case of the paper-grade pulp, the treatment with endoglucanase resulted in a considerable reduction of the pulp refining time without decrease in strength properties. While for the dis...
متن کاملFurther studies on the reactions of disulphides with sodium sulphite.
although the prior formation of an unstable intermediate is not excluded. 4. The poor conversion ofesters ofD-galacturonic acid into compounds ofL-galactonic acid appears to be due mainly to the reversible inhibition of the enzyme during the course of the reaction, and to a lesser extent to the instability of the galactonic acid derivative formed. The substance responsible for the inhibition of...
متن کاملStudies on resin purification process optimization of Eucommia ulmoides Oliver and its antihypertensive effect mechanism.
BACKGROUND Through research it is found that the barks, stems, fruits and flowers of Eucommia ulmoides contain various compositions, such as lignin, cycloalkane and phenylpropanoids. The modern pharmacological research shows that Eucommia ulmoides has many functions, such as anti-aging, antitumor and bone cell proliferation. This paper studied the resin purification process optimization conditi...
متن کاملPulp Chamber Temperature Rise during Resin Composite Polymerization
Objectives: To compare the pulp chamber temperature during illumination of resin-based composites using different light-curing units, and to assess the effects of a glass-ionomer (GI) base on the increase of pulp chamber temperature during polymerization. Material and Method: Standard occlusal cavities were prepared and restored with the adhesive bonding agent Clearfil Liner Bond 2V and the com...
