Abstract: The invention relates to the production of an optically detectable marking on a substrate. In the method, a substrate is taken, a printing ink containing a starch derivative in a solution form is printed on at least a selected first area and at least a selected second area is left unprinted, the printing ink is allowed to dry, in such a way that the starch derivative form a thermoplastic film in the said first area on the surface of the substrate, and an optically detectable marking is hot-pressed into the film. The invention also relates to a corresponding product. With the aid of the invention hot-pressable diffractive embossing is created at low temperatures, for example, on paper or board.

Abstract: The invention relates to a process for the crystallization of substances having a narrow metastable supersaturation zone. In the process the saturation of a solution is gradually increased and the solution is seeded for the crystallization. The seeding is performed at a seeding point which is selected in response to a signal received from said process indicating imminent or initial spontaneous nucleation. The process provides a good crystal yield and a crystalline product having a uniform crystal structure and a narrow crystal size distribution.

Abstract: The invention relates to a method of purifying phytosterol concentrates by contacting the phytosterol concentrate with a pressurized fluid. The invention also relates to the obtained purified phytosterol concentrate, foodstuff and animal feed premixes containing the same as well as to foodstuffs and animal feeds containing phytosterol concentrate.

Abstract: The present invention relates to a method for the production of a free flowing, compressible granulate which contains from 94% to 98% by weight of xylitol, another physiologically acceptable polyol such as mannitol, maltitol or isomalt and less than 1% by weight of water.
