Article Synopsis
- An experiment was designed to investigate how light intensity varies within citrus fruit, utilizing specialized equipment like a light box, spectrometer, and an optic fiber probe.
- Different light sources, including a 632 nm laser and a 50 W tungsten halogen lamp, were used to measure light changes at various positions in the fruit.
- Results showed that greater puncture depth led to increased light intensity and transmittance, with the citrus peel and stone significantly affecting light attenuation compared to the flesh, and the sample factor had minimal impact on the results.

The objective of the present research was to study the influence of four kinds of light intensity of near-infrared diffuse reflectance spectra on the determination of pear soluble solids content. Qualitative analysis of the four spectra showed that the differences between them were too slight to find. After further analysis by principal component regression (PCR), stepwise multiple linear regression (SMLR) and partial least squares regression (PLSR) as well as comparisons among them, the results of PCR model and SMLR models which had low correlation coefficients (r) were worse than those of PLSR model.
