Abstract:

To investigate the differences in intrinsic characteristics and the patterns of quality change under room-temperature and low-temperature storage among three tomato cultivars (‘Chuanguofan No.1’, ‘Hemei 809’, and ‘Hongshuo Haomai’) from Miyi County, Panzhihua, 90%-mature fruits of the three cultivars were used as experimental materials. A total of 12 indicators covering physical quality, nutritional quality, and oxidative stability were determined. The study was conducted by integrating principal component analysis, cluster analysis, and correlation analysis, and kinetic models for quality change during storage were established for the three tomato cultivars. The results showed that during storage, quality deterioration phenomena (including decreased fruit firmness, rising weight loss rate, malondialdehyde accumulation, and nutrient loss) were more pronounced in the 25℃ room-temperature group than in the 10℃ low-temperature group. Meanwhile, low-temperature treatment at 10℃ significantly elevated lycopene content and weakened the correlations among various quality indicators (P<0.05). Principal component analysis and cluster analysis results indicated that ‘Chuanguofan No.1’ achieved the highest comprehensive quality score. Based on tomato firmness, kinetic models of quality change were constructed by coupling the first-order kinetic equation with the Arrhenius equation. This study obtained quality change data of the three tomato cultivars under room temperature and low temperature conditions. Storage at 10℃ can effectively delay the fruit deterioration process of all three cultivars. For freshly harvested tomatoes, the comprehensive ranking in terms of physical quality, nutritional quality, and oxidative stability is as follows: ‘Chuanguofan No.1’> ‘Hemei 809’> ‘Hongshuo Haomai’. The established kinetic models enable rapid prediction of the shelf life of these three tomato cultivars, providing a reference for quality assessment of tomatoes stored at different temperatures.
