Abstract
Abstract. The level of fruit maturity for determining harvest time is an important factor that affects fruit qualities during ripening of ‘Cavendish’ banana. The quality resulting from that process can affect the level of consumer acceptance. During growth, fruit undergoes metabolism which produces energy and emit some kinds of infrared radiation. The thermal image processing technique was tried to detect fruit temperature at various levels of maturity of the fruits. Five bunches of ‘Cavendish’ bananas, with 8 hands each, from the top to the eighth hand were used for the experiment. Four fingers of each hand were analyzed for their thermal images, physical quality, chemical quality, and SEM. Each bunch was used as replications in the analysis. The standard method of determining the level of fruit ripeness was carried out to find the correlation with the thermal image. The results showed that the thermal image could distinguish the level of maturity and ripening, both the level of maturity between each hand on bunches of 'Cavendish' bananas and bananas in the ripe and mature phases. Thermal image results had a close correlation with physical (weight, diameter, fruit firmness) and chemical qualities (glucose, sucrose, starch) but had no correlation with fruit surface conditions (scanning electron microscope), ºBrix and free acid contents based on regression value. The hand at the top of the bunch had a higher temperature, which was 28.91℃ compared to the hand at the bottom, which was 28.71℃. Cavendish bananas on day 7 (ripe) had a higher temperature of 29.17℃ compared to bananas on day 1 (unripe) which was 28.92 ℃.
