FOOD
– & HOW TO STOP THE ROT
£100M’s wasted through incorrect packaging
Probably the biggest cause
of spoiled food, which costs the UK in excess of £100M every year,
is water vapour. Sometimes there is too much of it, sometimes not enough.
It is even the root cause of freezer burn. Yet controlling it is not particularly
difficult. Properly designed packaging, using materials with a suitable
permeability can substantially extend product life, prevent products from
drying-out or over-hydrating, and reduce waste.
Unfortunately, water vapour
does not act like liquid water - and materials that are a barrier to one
can allow the other to flow freely through – which is why so many
people use the wrong packaging materials. And that’s where Versaperm
comes in. Versaperm, a world leader in water vapour permeability measurement,
has introduced a quick and simple way to test most types of packaging,
films, coatings and containers. It’s available either by purchasing
the meter or via the company’s lab service.
Their WVTR (Water Vapour Transmission)
meter can cope with several samples at a time - often giving a reading
in as little as 30 minutes – whereas the conventional gravimetric
measurement technique takes several days and is significantly less accurate.
The meter is easy to use and
gives a series of digital readouts that can be recorded or simply read
off the LCD screen. It needs no re-calibration and requires, at most,
minimal training - yet it can give results that are accurate to a few
parts per million (with some samples a few parts per hundred million).
Sensitivities are in the range 0.05 – 3200g/m2/day.
Water vapour is omnipresent,
degrades products, causes sogginess, boosts biodegradation and reduces
shelf-life. In other cases, its loss dries products out, causing viscosity,
flavour and aesthetic problems. It can even move through a product, for
example pastry gaining moisture from the baked contents. The Versaperm
system can test the permeability of a huge range of products and packages
– from plastic and paper to pastry and from sugar coatings to foil
and pizzas.
