Patent number: 6693216Abstract: The present invention relates to calcium double salts having good preservative properties. Said salts can be used in foods, feeds, pet food, cosmetics and pharmaceuticals, food-contact items, silage, brewers' spent grains, pomace, food wastes, brewers' yeast, distillation residues and other wastes from the food industry or for leather treatment. These substances exhibit a considerably extended shelf life after addition of, or treatment with, one of the calcium double salts.Type: GrantFiled: October 9, 2001Date of Patent: February 17, 2004Assignee: Nutrinova Nutrition Specialties & Food Ingredients GmbHInventors: Nico N. Raczek, Christoph Mollenkopf
