BACKGROUND Sugar beet molasses is a viscous by-product of the processing of sugar beets into sugar. The molasses is known to contain sucrose and raffinose, a typical trisaccharide, with a well-established structure. Although sugar beet molasses contains various other oligosaccharides as well, the structures of those oligosaccharides have not been examined in detail. The purpose of this study wa...

Honey and agave syrup are high quality natural products and consist of more than 80% sugars. They are used as sweeteners, and are ingredients of cosmetics or medical ointments. Furthermore, both have low water content, are often liquid at room temperature and resemble some known sugar-based deep eutectic solvents (DES). Since it has been shown that it is possible to synthesize sugar esters in t...

[reaction: see text] The reactions of propargylic alcohols, aliphatic primary amines, and CO2 were conducted in CuCl/[BMIm]BF4 system to produce the corresponding 5-methylene-1,3-oxazolidin-2-ones under relatively mild conditions. The products could be conveniently isolated by means of liquid-liquid extraction. The solvent ionic liquid as well as CuCl catalyst can be recovered and reused three ...

Aqueous solutions of ethoxylated alcohols which form lyotropic liquid crystals at high concentrations (40-80%) were selected as model lubricating substances. Microscopic studies under polarized light and viscosity measurements were carried out in order to confirm the presence of liquid crystalline structures in the case of alcohol solutions with ethoxylation degrees of 3, 5, 7 and 10. Microscop...

The bulk of the radiation-induced degradation products of 2'-deoxyguanosine in oxygen-free aqueous solution have been separated by high performance liquid chromatography and charac­ terized by various spectroscopic techniques including fast atom bombardment mass spectrometry, ‘H NM R and circular dichroism. The two main decom position products result from the opening of the imidazole ring and f...

The method for the production of confiture has been improved, which consists in preliminary infrared processing fruits and vegetables by drying at a temperature 45...50 °C, followed grinding them to 1.5...2.5 mm. Introduction inverted syrup (to prevent sugar crystallization during storage confitures), subsequent boiling dry matter content 60...76% makes it possible obtain confitures with high o...

Mixtures of carbohydrates are often reported in the literature as deep eutectic solvents yet, most cases, their solid–liquid phase diagrams poorly characterized and no evidence is available to validate this classification. In work, binary systems composed sugar alcohols mannitol or maltitol meso-erythritol, xylitol, sorbitol, were experimentally determined. The results obtained reveal that thes...

potency from either freezing or heating. Indeed, interruption of the cold chain invalidates many disease prevention programmes worldwide. At the same time, it is now well established that extraordinary stability can be conferred on very labile biomolecules by drying them in sugar glasses – trehalose being the canonical example. In our laboratories at Cambridge Biostability Limited (CBL), we hav...
