Do you use preservatives and other additives in the production of fats?

We use no chemicals when processing fat - we heat it with steam (wet rendering) and then centrifuge the mixture. We never use preservatives. Antioxidants are added only at the customer's request, and only for pet food products. The type and the dose are the customer's choice and follow their own formulation, typically in the range of hundreds of ppm. If a specific product is prescribed on your side, state it with the enquiry.
