Oxidation is a primary cause of food spoilage causing rancidity, discoloration, off-flavors, changes in texture and more generally leads to decreased nutritional value. With Handary rosemary extracts, you can prevent a number of these degradation processes naturally. Guardox™ RA Rosmarinic acid is the most potent water soluble antioxidant compound from rosemary. With the unique deodorizing technology of Rosmarinic acid, Guardox™ RA is minimized the odor and bittiness at recommended usage level, making it suitable for delaying lipid oxidation or rancidity in a wide range of aqueous foods. |
