It’s often the case that common products contain chemical preservatives to extend their shelf life. Examples of chemical antioxidants that stop spoilage include BHA, BHT and ethoxiquin. These are relatively inexpensive and are commonly used to preserve fats. Various studies reveal that when these chemicals are used in abundance they can be harmful to human and animal health. For the purposes of preserving dry food, Yarrah only uses tocopherol, or vitamin E. Our wet food in cans and alu dishes is packaged in airtight containers and sterilized during production. Thus rendering further preservation measures unnecessary. Furthermore, no chemical preservatives are permitted in the raw materials supplied to us. Our products are fully free of chemical additives. Pretty healthy, then!
