Animal proteins are a valuable class of ingredients for animal nutritionists to use in feed formulas. Rendering is a process of both physical and chemical transformation using a variety of equipment and processes. The rendering process converts raw animal tissue into various protein, fat and mineral products – rich granular type meals and liquid fats with specific nutritional components. All of the rendering processes involve the application of heat, the extraction of moisture and the separation of fat. The temperature and length of time of the cooking process are critical and are the primary determinant of the quality of the finished product. The processes vary according to the raw material composition. These raw materials are collected and transported to a facility where it is ground into a consistent particle size and conveyed to a cooking vessel, either continuous-flow or batch configuration. Cooking is generally accomplished with steam at temperatures 115º to 145º C for 40 to 90 minutes depending upon the type of system and materials.
Unprocessed animal by-products and mortalities contain large numbers of microorganisms, including pathogenic bacteria and viruses. Unless properly processed in a timely manner, these materials provide an excellent environment for disease-causing organisms to grow and potentially threaten animal health, human health, and the environment.
Animal by-products are generally regarded as “high risk” and should be treated accordingly. Fats should be stabilized with an acceptable food- or feed-grade antioxidant added at levels recommended by our team of experts. Microbial recontamination is the single biggest risk factor and rendered meal should also be treated with an approved antimicrobial preservative for this use. Bitek has premium combination products available that will specifically protect all by-products meal against Salmonella and gram-negative pathogens including autoxidation.
Bitek was the first company to develop a combined liquid antioxidant, mould and Salmonella inhibitor. These products have a similar viscosity to water, enabling it to be added in a fine spray mist, ensuring maximum coverage and protection, particularly of the antioxidant components. Bitek's unique range of combination products offers the following benefits to the rendering industry:
Reduced pump maintenance and calibration.
Synergestic blend of antioxidants.
Active ingredients penetrate the entire meal to eliminate Salmonella and other gram negative pathogens within 48 hours.
Controlled release formulation ensures protection against recontamination during transport and storage.
Many years of experience, technical knowledge and a diverse product range consisting of combination products, liquids, powders and dusting powders allows Bitek to implement a comprehensive Rendering Safety Program for protection against Enterobacteriaceae including Salmonella, moulds and yeasts.
The Rendering Safety Program covers the following areas:
Identification and continuous monitoring of high risk areas within the rendering plants using SANAS accredited laboratories for substance analyses.
Treatment of finished product.
Plant disinfection including dusting with dusting equipment and flushing.
Formulations are operator friendly and non-corrosive to equipment.
