Problems solved by technology

[0004] For a long time, the post-harvest treatment of peaches in my country has been very weak. At present, the equipment for grading, packaging, and storage of fruits after picking in my country is seriously insufficient, and the storage and transportation technology is backward.
The storage capacity of peach fruit is also weak, and the storage method is backward, and there is no complete cold chain circulation system. Many fruit farmers do not even have the concept of post-harvest treatment; the processing enterprises are small in scale, with backward equipment, obvious seasonality, and lack of unified regulations
Due to the lack of related fresh-keeping technology, in order to prolong the storage period, reduce or eliminate the occurrence of storage diseases, and reduce the storage loss rate, it is of great practical significance to develop efficient storage and fresh-keeping methods for peaches after harvest.

Embodiment 1

[0016] A method for storing and preserving peaches, the method comprising the following steps:

[0017] (1) After the peaches are picked, select peaches with no mechanical damage, no rot, no mildew, and the same maturity, and spray 1L of thiophanate-methyl medicine on the surface of the peaches for treatment at a rate of evenly spraying 1L of thiophanate-methyl per 100 kg of peaches. The concentration of the bacteriocin is 500mg / L;

[0018] (2) After soaking, place it in a ventilated place to dry the surface moisture of the fruit; after drying the fruit, put it into a plastic bag, open the mouth and pre-cool the fruit to 25°C, then tie the mouth of the bag tightly and place it flat on the plastic bag In the fruit baskets, one layer is placed in each basket;

[0019] (3) Store the fruit baskets containing the fruits in a cold storage at 25°C. Since peaches are packed in plastic bags after picking, it is necessary to control the fresh-keeping bags without condensation and keep...

Embodiment 2

[0022] A method for storing and preserving peaches, the method comprising the following steps:

[0023] (1) After the peaches are picked, select peaches with no mechanical damage, no rot, no mildew, and the same maturity, and spray 1.1L of thiophanate-methyl drug evenly on the surface of the peaches at a rate of 100 kg per 100 kg of peaches. The concentration of thiophanate drug is 800mg / L;

[0024] (2) After soaking, place it in a ventilated place to dry the surface moisture of the fruit; after drying the fruit, put it in a plastic bag, open the mouth and pre-cool the fruit to 20°C, then tie the mouth of the bag tightly and place it flat on the plastic bag In the fruit baskets, one layer is placed in each basket;

[0025] (3) Store the fruit baskets containing the fruits in a cold storage at 20°C. Since peaches are packed in plastic bags after picking, it is necessary to control the fresh-keeping bags without condensation and keep the humidity at 85%.

Embodiment 3

[0028] A method for storing and preserving peaches, the method comprising the following steps:

[0029] (1) After the peaches are picked, select peaches with no mechanical damage, no rot, no mildew, and the same maturity, and spray 1.2L of thiophanate-methyl agent evenly on the surface of the peaches according to the ratio of 100 kg of peaches. The concentration of thiophanate is 1000mg / L;

[0030] (2) After soaking, place it in a ventilated place to dry the surface moisture of the fruit; after drying the fruit, put it in a plastic bag, open the mouth and pre-cool the fruit to 15°C, then tie the mouth of the bag tightly and place it flat on the plastic bag In the fruit baskets, one layer is placed in each basket;

[0031] (3) Store the fruit baskets containing the fruits in a cold storage at 15°C. Since peaches are packed in plastic bags after picking, it is necessary to control the fresh-keeping bags without condensation and keep the humidity at 85%.

Abstract

The invention provides a peach storage and freshness preservation method. After peaches are picked, 1 to 1.2 L of a thiophanate-methyl medicinal agent are sprayed to the surface of every 100 kg of peaches for peach surface treatment, and the concentration of the thiophanate-methyl medicinal agent is 500 to 1000 mg / L. The peach storage and freshness preservation method is simple, and the thiophanate-methyl medicinal agent is used for treatment of the peaches to maintain the stable content of soluble solids in the peaches and inhibit the reproduction of mold on the surface of the peaches so as to obviously reduce the incidence rate of rotting of the peaches, the problem of rotting of the peaches during storage is solved, proper temperature and humidity in a refrigeration house can be ensured, the storage time of the peaches can be significantly increased, and color and texture may not be destroyed.

Description

technical field [0001] The invention relates to a fresh-keeping technology for fruits, in particular to a storage and fresh-keeping method for peaches. Background technique [0002] China's peach cultivation area and output both rank first in the world. According to the 2014 China Agricultural Yearbook statistics, in 2013 my country's peach planting area was 765,900 hectares, with a total output of 11.9241 million tons, accounting for 61.59% of the total output of the world's major peach-producing countries. In general, peach consumption is still dominated by fresh food, mainly in the domestic market. The proportion of peach processing is less than 10% of the total output. Because of its strong seasonality, the ripening period coincides with the high temperature season, peaches are prone to rot and deterioration after harvesting, and various microorganisms are easy to breed during postharvest transportation and storage, often causing serious economic losses. According to ...
