Since 2012, Wing Pet Food established Witts Bio to focus on pet food nutrition and natural antioxidant sectors. After years of research on pet nutrition needs, Witts Bio successively launched premium pet food ingredients in various categories and fields since 2018.

Among them, hydrolyzed polypeptide powder products are processed with high-quality livestock and poultry raw material or marine fish in strict compliance with BRC (British Retail Consortium) system. Besides the functional values of polypeptides such as hypoallergenic and nutritious benefits, hydrolyzed polypeptide powder products also provide rich flavor, good & lasting palatability performance as well as significant advantages in freshness and oxidative stability.

With the rapid development of premium pet food and the gradual standardization of regulations and management, the use of natural antioxidants that are both safe and healthy in pet food is becoming more and more common. Witts Bio conducted many years of research in the field of natural antioxidants, and launched a series of natural antioxidant products in 2020.

Natural antioxidants mainly derived from plant extracts and microbial fermentation have prominent antioxidant and antiseptic functions as well as significant health and safety advantages. They can delay the oxidation of fats and oils, prevent off-flavors and nutrient loss, and effectively improve the shelf life of products. Because of their natural and safe characteristics, they have become the preferred choices of many premium pet food brands.
