A fructose-rich solution is prepared from a solid composition including fructose and glucose, in a process including i) admixing the solid composition including fructose and glucose with a selective solvent that consist for at least 80% wt of methanol to obtain a slurry of glucose-rich solids in a methanolic fructose-rich solution; and ii) separating the methanolic fructose-rich solution from the glucose-rich solids.

Systems comprising a first polynucleotide comprising a regulatory element operatively linked to an open reading frame encoding an invertase enzyme and a second polynucleotide comprising a repressible regulatory element operatively linked to an open reading frame encoding a glucose oxidase enzyme wherein the repressible element inhibits transcription in response to hydrogen peroxide are provided. Cells and compositions comprising a system of the invention, as well as methods using the system of the invention, are also provided, as is artificial honey.

The present invention relates to the production method and to compositions relating to a high-energy supplement/foodstuff based on inverted brown sugars originating primarily from sugar cane, providing advantages in response to exercise and superior sensory qualities in the opinion of athletes. The energy supplement/foodstuff, in liquid, gel or paste form, to which the present invention relates, has ideal nutritional compositions for combining this source of carbohydrates thrown sugars with equimolar proportions of glucose and fructose and a low concentration of sucrose) with other sources of carbohydrates, ergogenic products, vitamins, aromas, essential minerals, amino acids, proteins and other products of interest, with the aim of increasing physical performance for athletes or consumers in general.
