Freshness is a concern when
it comes to any consumable, but the pursuit, in particular, to keep
coffee in a state of near timeless suspension is much sought after. This
desire has perhaps drawn closer with the use of the FLAVIA office
vending machine 'Freshpack' designed by MARS Drinks, also used with
their tea products.
The process starts with its
storage before being packed. The coffee is kept in a nitrogen rich
environment, which helps to keep oxygen away that would otherwise
increase the rate of oxidation, leading the coffee to become stale and
lose its flavour.
The coffee is then put into
the freshpacks themselves. Each pack is composed of three layers:
laminate, aluminium and polyester. This combination helps to keep the
coffee safe from oxygen, light and moisture, and with the packs also
being nitrogen flushed, this combination really helps to clamp down on
the unwanted effects of oxidation.
The final push for
freshness occurs when the drink itself is made. Instead of a common
brewing chamber inside the machine that each pack empties into, the pack
itself functions as the brewing chamber. This prevents leftover
residues from previous drinks from affecting each coffee. The drink then
empties straight from the pack into a cup, likewise preventing
contamination from previous drinks.
