Food and beverage consumption and health
Coffee is one of the most popular beverages consumed worldwide and the most important food commodity from an economic point of view. Coffee processing can be divided into two stages: primary processing, in which the coffee fruits are de-hulled and submitted to drying, the resulting product being the green coffee beans, the main product
of international coffee trade
; and secondary processing, which comprises the produ
ction
of roasted and soluble coffee. Large amounts of solid waste
s are generated during
primary and secondary processing. These include coffee husks and pulp
, parchment,
spent coffee ground
s
, silverskin and others. These solid residues
pose several problems in
terms of adequate disposal, given the high amounts generated, environmental concerns
and specific problems associated with each type of residue
, and therefore there has been
an increasing interest in the evaluation of their chemical
profiles in order to propose
alternative uses for them. The role of coffee consumption
in preventing several disea
ses
has been well established, in association with substances such as caffeine
, chlorogenic
acid
s and others, indicating that it could be viewed as a functional beverage. The solid
wastes generated
in coffee production also contain similar amounts of phenolic
compounds
and thus have also been recently considered as potential sources of
antioxidants
and other relevant bioactive chemica
ls
. In view of the aforementioned, the
objective of the present study is to present a review of the works of research that have
been developed in order to establish the functional potential of coffee, either raw or
roasted and its byprodu
cts, e.g., solid wastes generated during primary and secondary
processing.
