Abstract:
Coffee is a common drink for almost all the people in the world and it is same to
Malaysian. Malaysian mostly drinks the instant standard coffee which is easy to
obtain from the market and shop. This is a study that focuses on the Malaysian
commercialized brands instant coffee and study the effect of the coffee the human
health. The study has shown that the commercialized brand of Malaysian instant
coffee affects the cardiovascular system primarily through the active ingredient
caffeine in the coffee powder of the instant coffee. The urine sample of the participant
that consumed the coffee was tested by the Fourier Transform Infrared Spectrometer
(FT-IR) to identify the chemical group inside the urine after consumed coffee. The
study of the Ultra-Violet/Visible spectrometer (UV-VIS) was done the urine sample of
participant after consumed the coffee. The results of the FT-IR shown that the urine
sample of the participant after drinking coffee is a healthy urine or normal urine and
that is no coffee chemical group can be found by using the FT-IR. As for the UV-VIS
result, the spectrum of the urine is different from each other and it is due to the
variables of the urine sample of each of the participant after the consumption of the
coffee. This study proved that the different of the urine sample of different human
showing the different of the adsorption of the UV-VIS. In conclusion, the Malaysian
commercialized brand instant coffee shows the short terms effect on the
cardiovascular system on the health of the Malaysian and the effect is varied due to
the individual who consume the coffee. More implementation of the research design is
needed so that the future research of the commercialized brand of coffee can be
carried out successfully and the results that obtained can be differentiated.
