| description | The purpose of this study was to determine the chemical composition of six fresh coconut milk samples sold in Kuala
Lumpur and to compare the results of chemical composition with pure coconut milk as reference using Malaysia Food
Composition, USDA Fresh Coconut Milk Composition and USDA Canned Coconut Milk Composition. The possible source
of adulterants that might present in coconut milk was also studied. Two fresh coconut milk samples from Pasar Imbi and
Giant Cheras was anticipated to be adulterated with water and a source of carbohydrate in order to thicken the coconut milk.
The protein content of fresh coconut milk sample from Pasar Imbi and Giant Cheras was 79.05% and 80.95%, respectively,
lower compared to the reference, while the fat content was 53.38% and 60.96% lower compared to the value of the reference.
However, the carbohydrate was 16.37% and 5.75%, while the moisture content was 12.84% and 25.77% higher compared to
the value of the reference. From these two potentially adulterated coconut milk samples, only coconut milk from Pasar Imbi
shown carbohydrate (corn flour) and water peaks of Fourier transform infrared (FTIR) spectra. The spectra of fresh coconut
milk adulterated with different concentration of corn flour were scanned and interpreted. Partial Least Square (PLS) regression
was used to quantitatively determine the concentration of corn flour in the coconut milk. The linear equation of the validation
obtained was y = 0.9161x + 0.3334 with R2= 0.9982 and RMSEC= 0.688. This can be suggested that FTIR could be a
potential tool in determining the coconut milk adulteration with corn flour for future study. |
