Product Highlights

CytoGuard® antioxidants from A&B Ingredients are natural tea-based antioxidants. They are formulated to be highly effective in reducing oxidation in animal and vegetable fats and oils, processed meats and seafood, processed foods and beverages, food colorants, cosmetics and nutraceutical products.  These powerful antioxidants are natural, clean label products that ensure the quality of our customers’  products throughout their shelf-life.

Our antioxidants are produced through an extraction process of the phenolic compounds that are naturally present in tea leaves.  No chemicals and/or solvents are used in the extraction process.  CytoGuard natural antioxidants have a clean flavor profile and at typical usage levels have a very little organoleptic impact on food products.

Our line of antioxidants provides a clean label solution that addresses the problems of oxidation in food manufacturing. For instance, rancidity in certain foods is the result of lipid material (fat) undergoing oxidation reactions that produce aldehydes, ketones, keta acids and other compounds that are responsible for odor and off-flavors. Not only does this cause flavor and quality loss, but it also affects the nutritional quality of your food product, not to mention health risks.  Our water-soluble antioxidants can help reduce oxidation at the lipid/water interface.  Our oil-soluble antioxidants can help oils last longer and help the foods fried in them stay fresher

CytoGuard antioxidants are available in both water-soluble and oil-soluble versions. Our customer service team can help you choose the right antioxidant for your application.

Among the benefits of CytoGuard natural antioxidants are:

  • All-natural
  • Non-GMO
  • Solvent-free extraction process
  • Clean label
  • Clean taste profile
  • High antioxidant activity
  • Oil and water-soluble
