Cayenne pepper (Capsicum annuum L.) is an important horticultural commodity with increasing consumption, but it is highly susceptible to post-harvest damage. Controlled Atmosphere Storage (CAS) technology has the potential to extend shelf life, but accurate and nondestructive quality measurement is crucial. This study aims to measure the physical quality and internal damage levels of chili peppers post-storage using X-ray computed tomography (CT). Chili pepper samples with and without stems were stored under three different atmospheric conditions: 0% O2; 2±1% O2; and 7±2% O2 (combined with 10% CO2, temperature 10°C, and relative humidity 90%), and compared with fresh samples as controls. Quality parameters measured included volume, surface area, solid volume, density, and greyscale. CT-based measurement results showed high accuracy for total volume and surface area parameters, making them a viable alternative for measuring these parameters. Respiratory activity was monitored in all treatments, with the highest CO2 production and O2 consumption observed in the 7±2% O2 treatment. The 7±2% O2 treatment demonstrated the best ability to maintain physical quality, characterized by the lowest quality changes compared to other treatments, both in treatments with stems (solid volume difference 5.29±3.48; greyscale difference 1.36±1.17; total volume difference 6.59±3.93; density difference 18.80±7.65; surface area difference 2.78±1.84; weight loss 2. 56±0.59) and without stems (solid volume difference 5.08±4.06; greyscale difference 0.49±0.56; total volume difference 5.62±4.32; density difference 15.72±3.24; surface area difference 4.84±3.13; weight loss 1.91±0.48). This study demonstrates the potential of X-ray CT as an effective nondestructive tool for evaluating the internal quality of post-harvest chili peppers.
