Problems solved by technology

[0002] Peach is easy to soften and rot after picking, and it is not easy to preserve and store. Therefore, keeping fresh of peach fruit after harvest has become an urgent problem to be solved in its cultivation and consumption.
At present, refrigeration is the most effective fresh-keeping method for fruits, but peach fruits are sensitive to low temperature, and frozen peach fruits are prone to chilling damage, resulting in decreased disease resistance and storability, resulting in rot and quality deterioration, and reduced edible value even completely lost

Embodiment Construction

[0014] The technical scheme of the present invention is described in detail below in conjunction with specific implementation examples:

[0015] 1. Peach fruit: choose peach fruit with about 80% maturity, good development and no mechanical damage, and late-maturing varieties (maturing in August to September) are more suitable;

[0016] 2. Pre-cooling: After picking, put the fresh fruit in a plastic frame (the bottom and the inner wall of which are covered with kraft paper to prevent mechanical damage), and place it as soon as possible at 20-25°C and 85-90% humidity for pre-cooling for 6~ 8h;

[0017] 3. Ultraviolet irradiation: The selected fresh fruits are subjected to ultraviolet irradiation treatment at a temperature of 20-25°C, the ultraviolet wavelength is 254nm, and the irradiation dose is 1.5-2.5KJ / m 2 . The ultraviolet radiation dose is determined by controlling the irradiation time, and the target dose is a(KJ / m 2 ), the ultraviolet intensity of the fruit surface w...

Abstract

The invention relates to the technical field of agricultural product preservation, and aims to provide a method for refrigerating and preserving juicy peach fruits. The method comprises the following steps of: precooling the juicy peach fruits; radiating the fruits by using ultraviolet rays; cooling gradually; refrigerating the fruits; heating gradually; and delivering the fruits from a warehouse. The cold injury of the juicy peach fruits in refrigeration can be remarkably prevented by treatment of the ultraviolet radiation and gradient temperature change, the rot is reduced, and the refrigeration preservation period of the juicy peach can reach 60 days. The method is convenient and effective to operate, is convenient to popularize and use, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of agricultural products, and aims to provide a method for cold-keeping and fresh-keeping of peach fruits for preventing chilling damage. Background technique [0002] Honey peaches are easy to soften and rot after picking, and are not easy to preserve and store. Therefore, keeping fresh after picking peach fruits has become a problem to be solved urgently in its planting and consumption. At present, refrigeration is the most effective fresh-keeping method for fruits, but peach fruits are sensitive to low temperature, and frozen peach fruits are prone to chilling damage, resulting in decreased disease resistance and storability, resulting in rot and quality deterioration, and reduced edible value Or even lose it completely. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fresh-keeping method for refrigerated peach fruit by ove...
