Abstract:
In order to prolong the storage time of kiwifruit and ensure its freshness, it is necessary to analyze the quality changes of kiwifruit during storage. The quality changes of kiwifruit during storage are simulated and predicted in this work. A quality change analysis model based on infrared spectroscopy was constructed. According to the model, the quality change prediction data of kiwifruit were obtained. Tthe storage period prediction model of weight loss rate of kiwifruit was also established. According to the model, the weight loss rate and the best shelf life of kiwifruit during storage were obtained. Furthermore, the change rule of quality of kiwifruit during storage was finally obtained. The results showed that there was a small gap between the quality change value and the actual value of kiwifruit during storage by using the designed prediction model. Among them, the predicted correlation coefficient of kiwifruit sample hardness is 0.806, and the predicted root mean square error is 1.112. The predicted results met the validity criteria, which showed that the proposed model can achieve the validity of the quality change of kiwifruit during storage. The model has potential practical application.
