PHYSICAL PROPERTIES AND CORRELATION BETWEEN NIRS SPECTRUM OF 'KHAO DAWK MALI 105' PADDY RICE
Thailand is one of the main rice exporters in the world.
The Thai rice cultivar
known Khao Dawk Mali 105, also known internationally as Jasmine rice.
The
quality of Jasmine rice is important and must be determined prior to distribution or
export.
The non-destructive methods that assure accurate results are the alternative
to time consuming conventional methods.
One alternative method, and the most
widely used, is near infrared spectroscopy (NIRS). This study focused on the use of
paddy rice spectrum to develop models for prediction of physical properties of
brown rice.
Entire paddy rice samples were scanned with a near infrared
spectrophotometer.
Reflectance spectra from 1400-2400 nm were recorded, the
spectra were then subjected to spectral analysis and model developed by using JMP
software version 10. A partial least squares (PLS) model was developed and
provided R2 values ranging from 0.39 to 0.79. The preceding analysis suggested that
it was possible to develop simple models by PLS from the NIRS spectra for
predicting physical properties of brown rice excepted for head rice yield of brown
rice (HRYB). It was obvious that whiteness of brown rice (WB), translucency of
brown rice (TB) and hardness of brown rice (HB) could be predicted and were
found adequate for rough screening aiming at the approximate predictions.
