Plum storage and transportation are prone to mechanical damage, brown heart disease at low temperatures, and rot and deterioration at high temperatures. It is very important during the harvesting and storage of plums, to reduce the loss in sales and to extend the market supply period.
Shandong Aoweite Biotechnology Co., Ltd. is a producer and exporter of preservatives. Manager Li, the sales manager of the company, accepted an interview with FreshPlaza to talk about the Logfresh preservative developed by the company for plums after harvest.
According to Manager Li, most of the plums are harvested in the high-temperature season when the fruits breathe vigorously, the nutrients are consumed rapidly, and they are perishable. "It must be cooled to below 4-5℃ within 24 hours after the plum is harvested, so as to effectively prevent the occurrence of brown and soft rot. At the same time, plums are a respiratory climacteric fruit, which has extremely high respiratory efficiency after harvesting and a fast ripening speed, and cannot rely solely on cooling and preservation."
In order to solve this problem, Shandong Aoweite developed Logfresh postharvest preservatives. "The product can effectively reduce the respiration of plums in a short time, which not only has a fast effect but also ensures that the important index of preservation can be achieved on the basis of long-term storage, that is, maintaining the original color, aroma and nutrients." Li said.
"The binding process between the active ingredient and ethylene receptor is irreversible. As long as the plum is treated for more than 12 hours, shortly after harvest, the long-term preservation effect can be achieved, and the preservation period can be extended by 1.5-3 times."

"Through one experiment, we found that the fruits of the plums that have not been preserved are completely mature, and the pulp tissue has been seriously rotted, and some have already become moldy. However, after fresh-keeping treatment, the pulp tissue of plums is still very tight, and the hardness and taste are excellent," Li said.
"For the preservation of plums, in addition to the Logfresh preservation card and the preservation slow-release sachet, we also have a very mature fruit preservation fumigation technology, which can realize the whole storage preservation of fruits in the cold storage or freezer. Its operation process is simple, and the preservation ingredients penetrate into every corner of the space, and the effect is more remarkable."
Shandong Aoweite Biotechnology Co., Ltd. was established in 1996, and has been engaged in the research and development of fruit preservation products for nearly 30 years. The products are sold to Argentina, Mexico, New Zealand, Ecuador, Kenya, Pakistan, India, Turkey, Serbia and other countries.
