The present volume, Volume 2 in this planned series on coffee,
deals with processing and follows on naturally from the first
volume on the chemistry of coffee, which described its numerous
constituents in the green (raw) and various product forms. We have
already remarked that coffee has great compositional complex ity,
and this complexity of understanding extends when we come to that
is, the many processes involved in the roasting consider its
processing; of green coffee and its subsequent conversion into a
consumable brew, especially through extraction and drying into an
instant coffee. The simple brewing of roasted and ground coffee
with water in the home also possesses considerable mystique and
needs know-how for optimal results. The choice of green coffees
from an almost bewildering array of different types available,
through species/variety differences and different methods of
processing from the coffee cherry to the green coffee bean, needs
understanding and guidance. Furthermore, various forms of
pre-treatment of green coffee before roasting are available. Some
of these are little known, but others such as decaffeination, for
those who desire roasted or instant coffee with little or no
caffeine, are now becoming well established. Finally, both the
processing of coffee cherries to coffee beans, leaving a range of
different waste products (pulp, hulls, husk, parchment, etc.), and
of roasted coffee after industrial aqueous extraction, leaving
spent coffee grounds, provide waste products that have found
considerable commercial value in different ways."
