Oxidation and development of rancidity is a major challenge for food manufacturers, reducing shelf-life and altering the quality and nutritional value of their products. Consumers’ interest in natural antioxidants has increased dramatically over the past years and the general trend requires the substitution of synthetic molecules (e.g. erythrobates, BHA, TBHQ, BHT, propyl gallate, and Sodium nitrite) with natural compounds.
Guardox™ BL is a natural bamboo leaf extract rich in Flavonoids, and is used as a multi-functional antioxidant flavoring for preventing lipid antioxidation, decreasing the use level and residue of nitrate or nitrite colorants, antibacterial, color retention, odor-removing and taste-modifying in various foods.
