Abstract: The present invention provides nutritional supplements comprising alginate, in combination with pectin, which will form hydrogels in the stomach when exposed to the low pH of the gastric juice. The formation of a hydrogel will lead to delayed release of sugars and other active ingredients in the stomach. The nutritional supplements can comprise high concentrations of sugars and complex carbohydrates without causing unwanted gastrointestinal symptoms.

Abstract: An ingestible particle comprising sodium bicarbonate, wherein the particle has size in the range of more than 1.0 mm but not more than 5.0 mm, with a thickness in at least one dimension of more than 1.0 mm but not more than 2.0 mm; and wherein the particle contains more than 50% (w/w) of the sodium bicarbonate. The ingestible particles are comprised in a nutritional supplement composition which is a suspension comprising the ingestible particles dispersed in an aqueous liquid, preferably a viscous aqueous medium.

Abstract: The present invention provides nutritional supplements consisting of an alginate hydrogel with sub-saturating amounts of calcium ions and comprising an aqueous solution comprising active ingredients, selected from sugars, complex carbohydrates, electrolytes, caffeine, and amino acids. The nutritional supplements allow for intake of carbohydrates without causing oral pH lowering and risk of dental caries, and without causing gastrointestinal discomfort while maintaining a high rate of intestinal uptake and oxidation of carbohydrates.

Abstract: An apparatus for extracting dissolved substances from water by means of a solvent comprises an extraction vessel, a mixing container, open at the top, in the lower portion the extraction vessel, and stirring means in said mixing container. The extraction vessel contains a desired quantity of solvent. The water is added in a continuous flow and is mixed with the solvent. The lighter solvent phase rises to the top of the apparatus, while the heavier water phase is continuously withdrawn through an annular space between the mixing container and the wall of the extraction vessel.
