Example Embodiment

[0013] Operation process: Late-ripening varieties of raspberries such as Qiufu, Heritage and Dingfeng should have no rainfall or irrigate 5 days before picking. Choose eight or nine mature fruits for picking to eliminate diseases, insects, damage, and rot. For inferior fruit, put the fruit into a plastic tray with a capacity of 2 Kg, and pre-cool it in a refrigerator at 0℃~3℃ for 18 hours to 24 hours within 12 hours after harvest; see figure 1 , And then put it into a plastic box-type air conditioning box (produced by the National Agricultural Products Preservation Engineering Technology Research Center) to keep fresh; each box can be loaded with three pallets2, and a bag of pierced raspberry preservative is placed on each side of the box 3. Then close the mouth of the box tightly and adjust the gas indicators in the box to make CO 2 The concentration reaches 4% to 7%. Put the plastic box-type air-conditioning box into a cold storage with a temperature of 0℃±0.5℃ for storage. T...

Abstract

The invention discloses a box-type air-regulating storage fresh-keeping method for a fresh-taken brambie berry, which is characterized by comprising the following steps of: harvesting fruits when the fruits are 80-90% ripe, selecting the fruits which have no mechanical injury, diseases and insect pests, rot and imperfect parts, loading the fruits in a plastic tray, pre-cooling the fruits for 18-24 hours at 0-3 DEG C within 12 hours after being harvested, and placing the plastic tray in a plastic box-type air-regulating case, placing holed brambie berry antistaling agent bags at two sides in the case, and then, tightly covering the opening of the case, and regulating the air in the plastic box-type air-regulating case through an air faucet to implement that the concentration of CO2 reaches 4%-7%; then, storing the plastic box-type air-regulating case at the temperature ranging from -0.5 DEG C to 0.5 DEG C, so that the storage period of the late-maturing brambie berry can be 40-45 days. The box-type air-regulating storage fresh-keeping method for the fresh-taken brambie berry has the positive effects that the brambie berry stored for 40-45 days is not rotted, so that market supply period of the fresh-taken brambie berry can be obviously prolonged, the fresh brambie berry is rich in special nutrition constituents, and the additional value of the fresh brambie berry can be increased by more than fivefold.

Description

technical field [0001] The invention belongs to the fresh-keeping technology of agricultural products, in particular to a plastic box-type controlled-atmosphere storage and fresh-keeping method for fresh raspberries. Background technique [0002] Raspberry, also known as tray and raspberry, is a plant of the genus Rubus in the Rosaceae family and belongs to the small berry category of shrubs. Because of its special nutritional and health functions, it is praised as the third-generation small berry at home and abroad. The cultivation of raspberry has a history of more than 300 years. Nowadays, more than 80 excellent varieties of raspberry have been bred in countries all over the world, among which there are more than 50 raspberry varieties in my country, which are widely distributed in the northeast, northwest, north and east of China. Southwest and other places. Raspberry has strong adaptability and is easy to manage. It can grow well on general soil, and is suitable for gr...
