Bottle 5 with sucrose assay control material for assay control purposes (measurement of the assay control material is not necessary for calculating the results.) Expiry date: see pack label 6. Bottle 6 with D-glucose assay control solution for assay control purposes (measurement of the assay control solution is not necessary for calculating the results.) The assay control solution does not contain sucrose and D-fructose because of their insufficient stability in aqueous solutions. Use the assay control solution undiluted.

Physicochemical Analysis of Carbonated Fruit Drink and Cola Beverage Prepared from Fructose Syrup 55 and Sucrose
In this study, carbonated fruit drink and cola beverage were prepared by sucrose and fructose syrup 55. The physicochemical properties of these samples were measured and compared. Three treatments for both types of drinks were considered: 100 % sucrose; 100 % fructose syrup 55; 50 % sucrose and 50 % fructose syrup 55. Changes in the sugar profile of both types of drinks and turbidity of carbona...
متن کاملEffect of Methyl Jasmonate and Sucrose on Endogenous Non-structural Carbohydrates in Petals and Leaves of Cut ‘First Red’ Roses (Rosa hybrida L.)
Effects of exogenously applied methyl jasmonate (MeJA) and sucrose on vase life and non-structural carbohydrate concentration in petals and leaves of cut ‘First Red’ roses were investigated. Roses were placed in sealed plastic containers and received MeJA vapour treatment (0.1 μL MeJA L-1) for 24 h at 20°C. Flowers were then placed in individual bottles containing 0 or 2% (v/v) sucrose solution...
متن کاملSucrose utilization by Zymomonas mobilis: formation of a levan.
1. Molar growth-yield coefficients of Zymomonas mobilis for glucose, fructose, glucose plus fructose, and sucrose are reported. Yield coefficients for sucrose are appreciably lower than those for the equivalent concentrations of glucose plus fructose. 2. Only 2.6% of [U-(14)C]glucose supplied in the growth medium is incorporated into cell substance by Z. mobilis utilizing glucose as the energy ...
متن کاملMelting behaviour of D-sucrose, D-glucose and D-fructose.
The melting behaviour of d-sucrose, d-glucose and d-fructose was studied. The melting peaks were determined with DSC and the start of decomposition was studied with TG at different rates of heating. In addition, melting points were determined with a melting point apparatus. The samples were identified as d-sucrose, alpha-d-glucopyranose and beta-d-fructopyranose by powder diffraction measuremen...
متن کاملCarbohydrates from Detarium microcarpum bark extract.
The bark extract of the medicinal plant Detarium microcarpum was analysed for its carbohydrate content by GLC-CIMS. Preparative HPLC of the benzoylated carbohydrate fraction led to the isolation of L-quino-1,5-lactone, D-(-)-bornesitol, D-pinitol, myo-inositol, sucrose, D-glucose, and D-fructose benzoates, which were characterised by NMR spectroscopy experiments.
متن کاملWetting effect on optical sum frequency generation (SFG) spectra of d-glucose, d-fructose, and sucrose.
We report a sum frequency generation (SFG) spectroscopy study of d-glucose, d-fructose and sucrose in the CH stretching vibration regime. Wetting effect on the SFG spectra was investigated. The SFG spectrum of d-glucose changed from that of α-d-glucose into those of α-d-glucose monohydrate by wetting. The SFG spectra showed evidence of a small change of β-d-fructopyranose into other anomers by ...
