    摘要: A method for producing a granulated riboflavin product comprises making a specific mixture of riboflavin, binder and water, followed by homogenizing the mixture and thereafter spray-drying the homogenized mixture so that granules are produced. The mixture has a relatively high vitamin and binder content but is reduced to a relatively low viscosity (via homogenization) so that spray drying can be performed.

    摘要: The present invention is a method of producing dry, alkali metal or ammonium carboxylic acid salt particles. In accordance with the invention, a molten carboxylic acid is mixed with a solution of an alkali metal-containing or ammonium-containing alkaline compound and the carboxylic acid and alkaline compound are reacted to form the carboxylic acid salt. Water is then removed from the carboxylic acid salt to produce dry, carboxylic acid salt particles. The feed ratio of the molten carboxylic acid and the alkaline compound is controlled to neutralize the carboxylic acid in the process.
