Abstract: A human use dietary product composition to reduce fat body mass without substantially reducing lean body mass, in obese or overweight patients includes a protein component and an amino acid additional component, the additional component containing a determined amount of lysine and/or tryptophan such that on the whole lysine and tryptophan in the composition have a weight ratio set between 2.5 and 4. To cope with typical protein-based diets drawbacks, the composition further includes an amino acid additional component with an amino acid selected from the group including lysine and/or tryptophan, in an amount such that on the whole the lysine and tryptophan in the composition have a weight ratio set between 2.5 and 4. The composition further contains a component that may be a polysaccharide or an enzyme, or a combination thereof. The enzyme may be ?-Galactosidase, Lactase, an enzyme having a flatulence reducing action, or a combination thereof.

Abstract: A method of determining the solid/liquid phase of an aqueous solution, characterized in that it comprises the following steps: a) subjecting said aqueous solution to a beam of photons; b) recording the Raman spectrum of the photons scattered by said solution in the wave number range between 2500 cm?1 to 4000 cm?1; and c) processing said recording in order to deduce therefrom the solid/liquid phase of said aqueous solution.

Abstract: A method of determining the concentration of a salt that may be present in a substance containing at least some water, comprising the following steps: a) recording the Raman spectrum of photons scattered by the substance in the wave number range 2500 cm?1 to 4000 cm?1; b) determining, for a given temperature of the substance, two points of said spectrum corresponding to two specific wave numbers; c) calculating the ratio of two magnitudes representative of said points to obtain a measurement ratio; and d) comparing said measurement ratio to a reference chart representative of the concentration of the salt for various temperatures as a function of the concentration of said salt. The method advantageously requires no taking of samples and may be contactless.
