When do Lingwu long jujubes ripen and hit the market? Their shelf life can be increased 10-fold
The fruit ripening period of Lingwu long jujubes is in late September. The market launch time is also at this time; whenever they ripen, they hit the market.
Yesterday, reporters learned from the Science and Technology Department of the Autonomous Region that the department, together with the Forestry Department, organized experts in forestry, fruits and vegetables, and food to conduct an on-site acceptance inspection of the room-temperature preservation research portion of "Key Technology Development and Research on Storage, Transportation and Preservation of Lingwu Long Jujubes," the region's first project tendered nationwide. The results showed that the shelf life of Lingwu long jujubes has increased 10-fold compared with before, achieving 30 days of room-temperature storage.
It is reported that Lingwu long jujubes have long entered high-end markets such as the southeast coast and Hong Kong, China, but because Lingwu long jujubes are prone to water loss, alcoholic fermentation, shriveling, flesh softening, browning and rotting after picking, their shelf life at room temperature is only 3 to 5 days, greatly hindering the market shelf life of Lingwu long jujubes. Last year, Lingwu long jujube preservation technology was listed as a major science and technology research project of the autonomous region and was openly tendered nationwide. The winning bidders - the College of Food Engineering of Tianjin University of Science and Technology, the Research Institute of Forest Resource Varieties of the Chinese Academy of Forestry, and the Institute of Agricultural Product Storage and Processing of the Gansu Academy of Agricultural Sciences - were organized to carry out technical research in 3 areas: disinfection and sterilization, application of special preservation film, and preservation coating agents and coatings.
After nearly two years of research, 3 sets of supporting room-temperature preservation technologies were developed. Lingwu long jujubes achieved 30 days of room-temperature storage, with a good-fruit rate of 91.8%, meeting commercial standards. The Science and Technology Department will organize domestic authoritative experts next year to systematically and comprehensively evaluate the 3 preservation technologies and determine the preservation technology and supporting processes to be mainly promoted in the industry.
