Abstract

The invention relates to the technical field of fruit and vegetable storage and fresh keeping, particularly to a bacterial inhibition and fresh keeping method for blackberry fruits. The method mainly comprises steps of blackberry fruit harvesting and treating, pre-cooling treatment, AITC fumigation treatment and sub-packaging, and low temperature storage, wherein the treatment concentration of an AITC essential oil during the AITC fumigation treatment achieves 5-15 mul / L. According to the present invention, the safe and natural plant-derived active substances are selected to carry out the fumigation treatment on the fruits so as to achieve the microorganism growth inhibition effect during the storage process, well maintain the blackberry fruit firmness, reduce the fruit decay rate, well maintain the fruit quality and prolong the storage period.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable storage and fresh-keeping, in particular to a method for antibacterial and fresh-keeping of blackberry fruit. Background technique [0002] Blackberry (Rubus spp.) is the aggregated berry of the vine blackberry of the genus Rubus L. in the family Rosaceae. It is native to North America. In 1986, it was first introduced from the United States by the Institute of Botany, Chinese Academy of Sciences and successfully promoted and cultivated. After more than 20 years of development, my country has become the main area for growing blackberries in Asia, and the total output in 2006 exceeded 10,000 tons. By 2009, blackberries had been successfully promoted and planted in the hilly area of ​​Lishui County, Nanjing, Jiangsu, with an area of ​​nearly 2,000 hectares, and the annual output of fresh fruit exceeded 10,000 tons, making it the largest blackberry planting base in China. In addition to ...
