Abstract: The current positive value of kiwifruit is on the market. Then, what problems should be paid attention to during the storage and preservation of kiwifruit? In order to reduce the loss of farmers, the reporter randomly visited Liu Xinghua, a professor at the School of Food and Engineering at Northwest Agriculture and Forestry University. Professor Liu analyzed the kiwifruit's storable varieties, harvesting, and storage methods. Selection of storable varieties At present, China's cultivated and wild kiwifruit lines mainly include Chinese kiwifruit, delicious kiwifruit, soft-jujube kiwifruit, and gezhi kiwifruit. The timely harvest of fruit of Chinese kiwifruit was 140 to 150 days, and that of delicious kiwifruit was 170 to 180 days. The current positive value of kiwifruit is on the market. Then, what problems should be paid attention to during the storage and preservation of kiwifruit? In order to reduce the loss of farmers, the reporter randomly visited Liu Xinghua, a professor at the School of Food and Engineering at Northwest Agriculture and Forestry University. Professor Liu analyzed the kiwifruit's storable varieties, harvesting, and storage methods. Selection of storable varieties At present, China's cultivated and wild kiwifruit lines mainly include Chinese kiwifruit, delicious kiwifruit, soft-jujube kiwifruit, and gezhi kiwifruit. The Qinmei and Haiwate in the Chinese kiwifruit line are two varieties that are currently cultivated in China and are of high quality and resistant to storage. The timely harvest of fruit of Chinese kiwifruit was 140 to 150 days, and that of delicious kiwifruit was 170 to 180 days. Fruit harvested at a proper time results in a big fruit, good taste and resistance to storage. At present, the most commonly used method for judging the maturity of kiwifruit is to determine the soluble solids content in the fruit. When the soluble solid content of Qinmei kiwifruit is 6.5% to 7%, it is suitable for picking. Kiwifruit is generally marketed from August to November. There are also differences in the maturity and time between early, middle and late-maturing varieties. The harvest period in Shaanxi Guanzhong region is suitable from late September to early October. Storage conditions 1. Temperature The storage temperature of kiwifruit is around 0°C. Chinese kiwifruit gradually softens after being stored at room temperature for 10 days, and then decays. At 0°C, it can generally be stored for about 100 days. 2. The suitable relative humidity for storage of kiwifruit is between 90% and 95%. The fruits stored under this humidity had a full appearance and the color and flavor were normal. When the relative humidity is 80% to 85%, the skin of the fruit apparently shrinks. Although it is edible, the commodity value is reduced. Under the relative humidity of 70% to 75%, the fruit rapidly dehydrated and shrunk, and the fruit could not be softened after ripening. After about 1 month of storage, it completely lost its edible and commercial value. Storage methods and management According to the needs and storage conditions, kiwifruit can take a variety of storage methods. Trench, kiln storage, etc. can be stored at room temperature for 20 to 30 days, and stored at 0°C to 2°C for approximately 2 months under refrigerated conditions. The storage time of the above methods is relatively short. For the kiwifruit that is planned to be stored for a long time, the effect of limited-air storage and controlled atmosphere storage is widely used in the cold storage during production. The storage period of the Qinmei kiwifruit generally reaches 4 to 6 months. When cold storage, the temperature should be controlled at about 0°C and the relative humidity should be 90%-95%. When using air-conditioned or limited-air storage, in addition to strict control of low-temperature and high-humidity conditions, a more suitable gas combination in the control environment is 2% to 3% oxygen and 3% to 5% carbon dioxide. In addition, kiwifruit is very sensitive to ethylene, and it must not be mixed with apples, which produce large amounts of ethylene. Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
