摘要
This study investigates the effects of different cold storage times (30 days—CS-30d, 40 days—CS-40d, and 50 days—CS-50d) on quality of “Cuiguan” pear fruits during shelf life. The data showed that, compared with 0 days of cold storage, the weight loss and rot rate of the fruit on the shelf increased, the hardness and nutritional quality of the fruit decreased rapidly, and the deterioration rate of the fruit was aggravated. By comparing the quality changes of three storage periods fruits during the shelf life at room temperature, it was found that the longer the refrigeration time was, the faster the quality of “Cuiguan” pear fruit declined in the later shelf life, and the easier the fruit deteriorated. Principal component analysis showed that the quality of Cuiguan pear fruits of CS-50d deteriorated fastest during shelf life at room temperature, followed by fruits stored for CS-40d and CS-30d. This provides a theoretical basis for selecting the cold storage time of “Cuiguan” pear. Practical applications At present, the effect of the refrigeration time of Cuiguan pear on the shelf at room temperature has not been reported. By comparing the changes of fruit quality during shelf life after different cold storage time (30, 40, and 50 days), the optimum cold storage time for Cuiguan pear was 30 days. It prolong the fruit duration and ensured that the fruit quality maintained a high level during shelf life at room temperature.
