THE RIGHT MODIFIED ATMOSPHERE FOR EVERY PRODUCT PROTECTIVE GASES › OXYGEN (O2) essentially causes food to spoil due to oxidation and forms the ideal preconditions for aerobic microorganisms to grow. As a result, oxygen is frequently excluded from modified atmosphere packaging. In some cases – typically red meat – processing is deliberately carried out with high oxygen concentrations, in order to prevent the red colour from becoming ‚pale‘ and inhibit the growth of anaerobic organisms. › CARBON DIOXIDE (CO2) is colourless, odourless and tasteless. It has an oxidation-in-hibiting and...

› FISH AND SEAFOOD PRODUCTS Product Raw low-fat fish Raw high-fat fish Shellfish and crustaceans Cooked/Smoked fish Examples of gas mixture compositions in % Product Hard cheese Soft cheese Sliced cheese Cream cheese Yoghurt Milk powder Examples of gas mixture compositions in % Fish and seafood are some of the most sensitive foods. They are at risk of rapidly declining in quality and spoiling even shortly after the catch. The reason for this lies in the neutral pH value as an ideal precondition for microorganisms as well as special enzymes that negatively affect taste and odour. Fish, which...

› FRUIT AND VEGETABLES Product Fresh fruit and vegetables Cooked vegetables Examples of gas mixture compositions in % › BREAD AND CAKE Product Crispy breads Cakes, biscuits Examples of gas mixture compositions in % With bread, cake and biscuits, the shelf life is primarily affected by potential mould formation. A high standard of hygiene during production and packaging can significantly minimise this risk. Packaging involving a modified atmosphere with CO2 and without oxygen extensively prevents the products from becoming mouldy and extends the shelf life. To prevent the packaging from...

› PASTA AND READY-MADE MEALS Product Ready-made meal Pasta/Pizza Sandwiches Product Snacks/Crisps/Peanuts Examples of gas mixture compositions in % Examples of gas mixture compositions in % The nature and composition of fresh pasta and, in particular, readymade meals are very different. Above all, multi-component products such as ready-made pizzas or sandwiches contain many different foods with differing shelf lives and spoilage properties. In the majority of cases, modified atmospheres can significantly extend the shelf life without using oxygen. Mixtures of CO2 and nitrogen are used here....

PRODUCT OVERVIEW › GAS MIXERS AND METERERS GAS MIXERS AND METERERS In the packaging process the air inside the package is replaced by a gas or a gas mixture. Today, in most of the cases gas mixers are used to create these gas mixtures. MAP gas mixers by WITT provide controlled gas quality and safety in your packaging process – for germfree and preserving food. But above all they offer high flexibility to the user. At the push of a button different mixtures can be produced in shortest time on one packaging line, depending of the requirements of the product. WITT offers gas mixing and...

APPLICATION Gas mixing systems for 2 or 3 defined gases, designed for a variety of applications, particularly for all areas with constant or varying mixed gas flow demands. APPLICATION Electronic flow control system for modified atmosphere packaging (MAP) to suit flow pack machines in the food industry and for room atmospheres e.g. for the storage of fruit and vegetables. Total control of the O2 residual in the pack. FEATURES ➜ YOUR BENEFITS • Infinitely variable mixture settings ➜ Always the correct gas mixture • Proportional mixing valve for two gases with %-scale Individual mixing valves...

PRODUCT OVERVIEWx › GAS ANALYSERS GAS ANALYSERS Gas analysers are essential for quality control in the MAP process. The monitoring can be done as permanent analysis directly during the packaging process or after the packaging process as sample test. For the permanent analysis a gas analyser module is integrated into the gas mixing system. The gas analyser monitors the correct composition of the gas mixture. The sample testing is part of the quality control of almost every company who is working with modified atmospheres. Via a needle a sample is taken from the package. High quality WITT gas...
