Quality assessment of Indonesia
specialty coffee bean using near infra red
Coffee is one of the most popular
beverages consumed worldwide. Primarily two species of coffee are
available commercially, Arabica and Robusta. Arabica coffee
generally has a higher price than Robusta coffee since its beans
have a more pronounced and finer flavor than Robusta beans. Due to
this price difference, there is a tendency of adulterating Arabica
with Robusta coffee bean. Therefore, as far as mislabeling or
eventual fraudulence are concerned, it is important to identify and
classification the bean variety. In today’s marketplace coffee
identification and classification is as crucial to cup quality as it
is to consumer requirement for origin and species specification. In
order to obtain top market prices, methods of efficient,
inexpensive, and highly accurate identification of coffee origins
and characteristics are needed. Near infrared (NIR) will fulfill
these requirements.
Indonesia as a coffee exporter country has several geographical
indication or specialty coffee. Some of them are famous in the world
such as Mandheling and Java Coffee, and Civet-Cat Coffee (Kopi
Luwak) the expensive one, maybe most expensive coffee in the world.
There are several other specialty coffee in Indonesia and through
this paper it will be assesment it’s origin and quality. There are
need to develop an instrument to prevent adulteration about coffee
origin and quality. There are several way to assignment coffee
quality, one of them is using Near Infrared Reflectance (NIR)
device. The experiments will conduct in several phase.
