Packaging The next step to be considered is the composition of atmosphere inside the bottles. My packaging system will incorporate a Modified Atmosphere Packaging(MAP), that would be suitable for a long term storage without addition of preservatives. In some packaging systems, no head space is left during packaging so as to eliminate oxygen from the system to inhibit growth of organisms. But absence of oxygen will lead to anaerobic microbial growth, which will cause off odours & flavours. This can be pathogenic and even fatal in case of clostridium botulinum which produces botulinum toxin in absence of oxygen. A modified atmosphere suggesting elevated levels of carbon dioxide and lowered oxygen levels (most commonly both oxygen & carbon dioxide at 5% )
