Judul: Deteksi Chilling Injury pada Buah Mangga Gedong Gincu dengan Menggunakan Near Infrared Spectroscopy (NIRS)
Abstrak: Low temperature storage is a common method to extend postharvest life of fruits. However, for sensitive fruits such as mango low temperature storage may cause chilling injury. Chilling injury is one of serious problem for mango stored under low temperature. The symptoms of chilling injury during storage associated with the change in pH due to ion leakage. Chilling injury can be detected during storage destructively, but it will require time and a lot of samples. Alternatively, the detection can be performed non-destructively by using near infrared (NIRSpectroscopy). The purpose of this research is to build the NIR calibration models for predicting ion leakage relating to change in pH and the detection of chilling injury symptoms can be done through ion leakage existence. Reflectant NIR measurements conducted on mango fruit stored at a temperature of 8 °C and 13 °C. Determination of chilling injury symptoms was predicted based on change in pH and the rate of ion leakage forming. The analysis showed that NIR spectroscopy was able to predict the change in pH during storage of mango fruit at a temperature of 8 °C based on reflectance and PLS method. Moreover ion leakage could also be predicted properly through the pH of the NIR predictions. The developed method could detect the chilling injury on mangoes after three days storage at a temperature of 8 °C.

Abstrak: Low temperature storage is a common method to extend the self life and to maintain the quality of mango. However, low temperature storage may cause mango experience the chilling injury. Study on the chilling injury symptoms of mango stored under low temperature storage will be very important in order to understand better mathod to reduction of chilling injury. The objective of this study was to examine the chilling injury symptopms of mango fruits stored at 8, 13 °C and room temperature. Chilling injury symptoms was determined from the ion leagake which measured from the changes in the value of electric conductivity with time. The quality of mango during storage were evaluated from the changes in weight loss, respiration rate, colour, firmness, total soluble solid as well as organoleptic test. The result showed that mango fruits experienced chilling injury at days 4 at storage condition of 8°C. The chilling injury symptoms at days 4 was showed by the highest value of slope from graphic of total percentage of electric conductivity value with time. This phenomenon of chilling injury symptoms at 8°C was also indicated by quality parameter i.e respiration rate, weight loss, total soluble solid, change in colour, firmness and organoleptic test.
