- Aseptic vs Retort processing method makes all the difference in the quality of the RTD product
RTD shakes are typically made using one of two processing methods – retort processing or aseptic processing. The processing method makes all the difference in the quality of the RTD and the ultimately, the results you can expect from using it. Retort Processing… Most RTD’s on the market today are packaged in metal cans – just like soda pop. Canned RTD’s are made using the retort processing method – a food processing method that’s over a century old. Retort processing is a method whereby the canned RTD’s are sterilized by superheating them for 45 minutes at temperatures of up to 300 degrees Fahrenheit. This effectively sterilizes the cans and eliminates any bacteria and contamination. While heating the RTD’s for a long period of time effectively sterilizes both the metal can and the RTD liquid inside, this excessive heat exposure (overcooking) – also does something else: it denatures the proteins in the RTD. You see, proteins are made of amino acids that link together and form chains called peptides. When proteins are exposed to extreme heat for long periods of time, proteins become cross-linked – the structure breaks down and becomes denatured - and the protein is rendered, biologically speaking, inferior. Not surprisingly, testing shows that up to 90% of proteins in your typical canned RTD may become denatured because of retort processing. Additionally, the liquid in canned shakes are exposed to metal inside of the can. And, when heated, it is possible that metal residues may leech from the can and into the RTD liquid – giving it a “metallic” taste. So, by drinking a canned RTD, you’re not just drinking biologically inferior denatured protein, but you may also be getting a metallic taste. Aseptic Processing… By contrast, aseptic processing is a relatively new and innovative food processing method that uses the latest in food processing technology. Aseptic processing differs from retort processing in that it incorporates a container made from multilayered packaging materials instead of a metallic can, and involves minimal processing and flash heat exposure. Aseptic processing ensures that your RTD doesn’t taste metallic – because the liquid never comes into contact with a metal container. Also, aseptic RTD’s don’t need to be refrigerated – the multilayer packaging locks in the proteins, vitamins and minerals and locks out light, moisture and air. Aseptic RTD’s keep a constant air-tight internal environment that allows your RTD to keep for months without needing to be refrigerated – and this is accomplished without the need for harmful preservatives. ASEPTIC PROCESSING PRESERVES UP TO 90% OF THE PROTEINS AND VITAMINS. YOU GET A POWERFUL AND POTENT RTD THAT DELIVERS RESULTS!  In fact, aseptic processing is so advanced that the prestigious Institute of Food Technologists (IFT) called aseptic processing “the most significant food science innovation of the last 50 years...ahead of even the microwave!” and went on to conclude that “Compared with traditional canning techniques, the aseptic process allows a substantial reduction in the time and temperature necessary for sterilization. That, in turn, increases nutrient retention and flavor for ensuring safety.” Conclusion: Aseptic vs Retort processing effects the quality of your RTD. As you can see, Aseptic processing is clearly superior to the outdated Retort method. For best results, choose a high quality aseptic-processed RTD shake
