Embodiment 1

[0047] A compound storage and fresh-keeping method for juicy peaches is carried out in the following steps:

[0048] (1) Raw material preparation: Harvest the peaches that have reached the appropriate harvesting period in time, and transport them to the laboratory within 6 hours, and select the peaches that are eight mature, uniform in size, free from mechanical damage, and free from diseases and insect pests, and set aside.

[0049] (2) Pre-cooling: Place the peach raw materials in step (1) in a pre-cooling room at 0°C for pre-cooling. After 24 hours of pre-cooling, the temperature of the peach pulp reaches 3°C.

[0050] (3) N 2 Pretreatment: put the peaches in step (2) into a glass jar, place it in a cold storage at 0°C and a relative humidity of 85-95%, and fill it with N 2 4 h (to ensure that the tank is always 100% nitrogen).

[0051] (4) Seal the peaches in step (3) with a polyethylene film bag with a thickness of 0.01 mm. Each bag contains 4 peaches, and put them in ...

Embodiment 2

[0054] A compound storage and fresh-keeping method for juicy peaches is carried out in the following steps:

[0055] (1) raw material preparation: same as embodiment 1;

[0056] (2) Pre-cooling: Place the peach raw materials in step (1) in a 2°C pre-cooling room for pre-cooling. After 12 hours of pre-cooling, the temperature of the peach pulp reaches 8°C.

[0057] (3) N 2 Pretreatment: Put the peaches in step (2) into a glass jar, place it in a cold storage at 3°C ​​and a relative humidity of 85-95%, and fill it with N 2 12 h (to ensure that the tank is always 100% nitrogen).

[0058] (4) Seal the peaches in step (3) with a polyethylene film bag with a thickness of 0.04 mm, and pack 8 peaches in each bag, and place them in a cold storage at 3°C ​​with a relative humidity of 85-95%, and the storage period is 34 d.

[0059] (5) Take the peaches in step (4) out of the polyethylene film bag and place them at 27 °C for 4 days.

Embodiment 3

[0061] A compound storage and fresh-keeping method for juicy peaches is carried out in the following steps:

[0062] (1) raw material preparation: same as embodiment 1;

[0063] (2) Pre-cooling: Place the peach raw material in step (1) in a 2°C pre-cooling room for pre-cooling. After 24 hours of pre-cooling, the temperature of the peach pulp reaches 5°C.

[0064] (3) N 2 Pretreatment: put the peaches in step (2) into a glass jar, place it in a cold storage at 0°C and a relative humidity of 85-95%, and fill it with N 2 6 h (to ensure that the tank is always 100% nitrogen).

[0065] (4) Seal the peaches in step (3) with a polyethylene film bag with a thickness of 0.02 mm, and pack 5 peaches in each bag, and place them in a cold storage at 0°C and a relative humidity of 85-95%. The storage period is 30 days. d.

[0066] (5) Take the peaches in step (4) out of the polyethylene film bag and place them at 25 °C for 4 days.

Abstract

The invention belongs to the technical field of storage and preservation of agricultural products, and in particularly relates to a composite storage and preservation method for juicy peaches. The composite storage and preservation method comprises the following steps: collecting juicy peaches at harvest time in time, placing the juicy peaches in a precooling room for precooling at the temperature of 3-8 DEG C, and then transferring in a glass pot, placing the glass pot with the juicy peaches in a refrigeratory with temperature of 0-4 DEG C and relative humidity of 85-95%, introducing N2 for 4-12h, sealing and packaging by using a polythene film bag, placing in the refrigeratory with the temperature of 0-4 DEG C and relative humidity of 85-95% till the storage period is ended, taking out of the juicy peaches out of the polythene film bag, and storing at the temperature of 22-27 DEG C for 4 days. With the adoption of the composite storage and preservation method, the defects of not obvious storage effect and potential safety hazards in the prior art are overcome, the postharvest aging process and the degrading of quality of the juicy peaches are delayed, the low-temperature shelf-life of the juicy peaches is prolonged, and the normal-temperature shelf-life of the juicy peaches is prolonged.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a compound storage and preservation method of juicy peaches. Background technique [0002] Juicy peach is a good product among fresh peaches. It is sweet and tender, juicy and less dregs, nutritious and beautiful, and the food quality is excellent. It is very popular in the market. However, the water content of peaches is high, reaching more than 90%, and the peel is thin, so it is very vulnerable to mechanical damage after harvesting. In addition, when harvesting is in the high temperature season, the fruit will ripen and age quickly. Studies have shown that the shelf life of juicy peaches at room temperature is only 3-5 days. The quality deterioration caused by ripening and senescence is a bottleneck problem in the development of the peach industry. At present, one kind of storage and preservation method is mostly used in ...
