example 1

[0016] Example 1: After harvesting sweet persimmons, pick 8 mature sweet persimmons without injury or disease, soak them in 3% saline solution for 10 minutes, remove them, and place the drained persimmons in a sealed container. Fumigate with 1 μL / L of 1-methylcyclopropene and 5g / L of s-butylamine, after 24 hours, inject 35% pure carbon dioxide gas, seal for 12 hours, take it out and put it into a 0.02mm thick PE fresh-keeping bag with the function of regulating air and moisture permeability Then tie the mouth of the bag tightly, put it in a box, and put it in 15°C to keep fresh for 40 days, and the hardness can be kept at 8KG / CM 2 .

example 2

[0017] Example 2: After the sweet persimmons are harvested, pick 8 mature sweet persimmons without injury or disease, soak them in 0.5% saline solution for 20 minutes, remove them, and place the drained persimmons in a sealed container Fumigate with 2μL / L 1-methylcyclopropene and 8g / L s-butylamine, after 12 hours, inject 60% carbon dioxide gas, seal for 3 hours, take it out and put it into a 0.06mm thick PE fresh-keeping bag with the function of regulating air and moisture permeability , and then tie the mouth of the bag tightly, pack it into a box, and put it in 15°C to keep fresh for 30 days, and the hardness can be kept at 8KG / CM 2 .

example 3

[0018] Example 3: After the sweet persimmons are harvested, pick 8 mature sweet persimmons without injury or disease, soak them in 5% saline solution for 30 minutes, remove them, and put the dried persimmons in a sealed container for storage. Fumigate with 1.5μL / L 1-methylcyclopropene and 10g / L sec-butylamine, after 18 hours, inject 50% pure carbon dioxide gas, seal for 8 hours, take it out and put it into 0.08mm thick PE with the function of regulating air and moisture permeability to keep fresh Put it in the bag, then tie the mouth of the bag tightly, put it in a box, put it in 15℃, it can keep fresh for 50 days, and the hardness can be kept at 8KG / CM 2 .

[0019] Example 4: After harvesting sweet persimmons, pick 8 mature sweet persimmons without injury or disease, soak them in 4% saline solution for 30 minutes, remove them, and place the drained persimmons in a sealed container. Fumigate with 1.8μL / L 1-methylcyclopropene and 10g / L sec-butylamine, after 18 hours, inject 45...

Abstract

The invention relates to a normal-temperature refreshing method of Baoshan persimmon, which comprises the following steps: after harvest of the persimmon, selecting the persimmon which is almost ripe and has no damage or diseases, spreading preservative consisting of table salt, 1-MCP, sec-butylamine and carbon dioxide on the selected persimmon; bagging in a polyethylene film refreshing bag; and then sealing and preserving at normal temperature. The normal-temperature refreshing method is simple, economical and practical and is easy to mass promotion. The persimmon preserved by the method can be kept at normal temperature for 30-50 days. The method has good preservation effect on the persimmon and can keep the fresh appearance and good taste of the preserved persimmon also can keep the hardness and quality of the preserved persimmon; and the persimmon preserved by the method meets the indexes of product standard and has longer shelf life, good market prospects and high economic and social benefits.

technical field [0001] The invention belongs to a fresh-keeping method for fruits, in particular to a fresh-keeping method for Baoshan sweet persimmons at normal temperature. Background technique [0002] Said Baoshan sweet persimmon in the present invention is a treasure among the persimmons that my country introduces from Japan. Its fruit is large (average single fruit weight 220 grams), good shape, bright color, thin skin, sweet taste, crisp and refreshing, high nutritional and health value. Persimmon is very rich in nutrients. Compared with apples, except that the content of zinc and copper in apples is higher than that of persimmons, other ingredients are dominated by persimmons. As a foreign saying goes, "An apple a day keeps the doctor away." However, when it comes to preventing heart vascular sclerosis, persimmon is far more effective than apples, and it can be called the king of fruits that are good for heart health. So "an apple a day is not as good as a persimmo...
