Embodiment Construction

[0012] The present invention is realized like this, see figure 1 :

[0013] (1) Nanguo pears are harvested at the right time

[0014] Harvest from September 5th to 15th.

[0015] (2) Nanguo pears are pre-ripe before storage

[0016] Nanguo pears harvested at the right time should be pre-ripened at room temperature for 3-5 days.

[0017] (3) Preservative treatment before storage

[0018] It can be wrapped with fresh-keeping paper treated with antioxidants. The method is: soak the diluted preservative with paper to make fresh-keeping wrapping paper. Before storage, wrap the preripe fruit in paper, put it in a plastic box, and put it on the storage shelf for refrigeration.

[0019] It can also be impregnated with Nanguo pear anti-browning inhibitor. The method is: dilute the original solution with clear water, dip the fruit, drain the water and dry it, put it in a plastic box for pre-ripening, and place it on a storage shelf for refrigeration.

[0020] You can also apply 1-...

Abstract

The Nangu pear preserving and browning preventing technology includes timely picking, pre-maturing before storing, treating with preserving agent and management in the storing period. The timely picking is favorable to the mature of fruit and can prevent disease and browning of the stored fruit; the pre-maturing before storing results in good storing effect; the treating with preserving agent before storing can inhibit the browning in the late storing period; and the management in the storing period provides proper Nangu pear storing temperature, humidity and ventilation condition. The present invention can prevent browning of stored Nangu pear and raise the quality of stored Nangu pear effectively.

Description

technical field [0001] The invention relates to a fruit storage and preservation technology, in particular to a Nanguo pear storage and preservation anti-browning technology. Background technique [0002] Nanguo pear is a specialty fruit in Liaoning Province, originally produced in Shangduizhangshi Village, Dagushan Town, Qianshan District, Anshan City. The storage and preservation technology of Nanguo pear has been studied for many years by scientific and technical personnel and university experts, and remarkable results have been achieved. Through mechanical refrigeration, it can be stored and kept fresh for 4-6 months, which will increase farmers' income and increase agricultural efficiency and receive significant economic and social benefits. At present, the main problem in the long-term storage of Nanguo pear is that in the later stage of storage, as the fruit tissue ages, tissue browning occurs in different degrees in the peel and pulp, especially the browning of the ...
