What is ROSLEV

Leaven’s rosemary extract-based antioxidants effectively extend shelf life across diverse applications, including pet food, meat, poultry, fats, oils, and snacks, by delaying oxidation. Our rosemary product provides a natural alternative to synthetic antioxidants such as Tertiary Butylhydroquinone (TBHQ), Butylated Hydroxyanisole (BHA), and Butylated Hydroxytoluene (BHT).
