Publication number: 20210192369Abstract: A method for predicting the quality and shelf life of fruits or vegetables includes: recording ambient temperatures of the fruits or vegetables continuously using a temperature recorder from the beginning of plucking the fruits or vegetables and throughout entire supply chain including harvesting, grading, storage, transport and shelf period, determining an effective accumulated temperature value of the fruits during the entire supply chain, and predicting marketable fruit rate and nutritional quality of the fruits based on the effective accumulated temperature value. The marketable fruit rate, firmness and vitamin C content negatively correlate with the accumulated temperature value, and thus it is possible to predict the marketable fruit rate and storage quality of fruits based on the effective accumulated temperature values of the fruits or vegetables during the post-harvest storage and shelf period.Type: ApplicationFiled: November 25, 2019Publication date: June 24, 2021Applicant: South China Botanical Garden, Chinese Academy of SciencesInventors: Hongxia QU, Yijie ZHOU, Zhongsuzhi CHEN, Meiying HE, Hong ZHU, Ze YUN, Ying WANG, Yueming JIANG
