| Abstract:
Recent research has concentrated on developing nondestructive measurement methods for detecting the internal quality of fruits. Most of these studies using Near Infrared Reflectance Spectroscopy (NIRS) were conducted on fruits that have a more or less flat surface on which the sensor was positioned, such as apples, oranges, peaches, tomatoes, grapes, mangos, kiwifruit, bananas, and melons. The objective of this research was to investigate the NIR capability in order to predict internal quality of fruit with a jagged (uneven) surface, such as the bitter gourd (Momordica charantia L.) cv. Murubushi. An NIR wavelength range of 600-1100 nm, was used to detect soluble solid content, moisture content, and the chlorophyll a and b contents. The results showed that NIR Spectroscopy has the potential to predict the internal qualities of a fruit with jagged surface. | |
