Happier customers

Maziak have supplied and installed an increasing number of Modified Atmosphere Packaging (MAP) systems, also known as ‘gas flushing’. This process has numerous benefits to those involved in the food packaging industry. The products are of a higher quality due to the preservation of flavour, aroma, texture and nutritional value, which can in turn lead to increased sales. Also, the shelf-life of products is extended, by weeks and even months, opening up new sales opportunities farther afield.

This is a simple process of flushing packaged foods with inert high purity nitrogen in order to reduce the oxygen level below 1%, which slows down aerobic decay and deterioration caused by oxidisation, and results in fresher food both in terms of taste and appearance. The use of nitrogen as a filler gas also provides a pressurised atmosphere that prevents packages from collapsing, and gives a smoother result than vacuum packaging.

Nitrogen flushing is not new to the food industry but the widespread use of mini storage tanks to supply the nitrogen has been inefficient and expensive.  This is due to the need for (and cost of) refills and the possibility of production downtime if the refills are late arriving. There are also safety risks associated with the need to manhandle and store the gas cylinders, plus UK suppliers of liquid nitrogen are extremely limited.

In many cases our installations have involved replacing other nitrogen sources with a generator such as NITROSourceTM from Parker.  Once installed, this is a cost effective alternative, with excellent pay back, delivering on-demand food grade nitrogen with purity of up to 99.999%.
