Embodiment 1

[0024] A method for postharvest preservation, storage and transportation of peach, comprising the following steps:

[0025] (1) Harvesting and pretreatment: In rainless weather, select 8-9 ripe peaches, pick them before 9 am or after 5 pm, keep the stalks, and place them on wooden or plastic cushioning materials. In the turnover box; after picking, remove diseased and insect fruit, softened fruit, deformed fruit, mechanically damaged fruit and defective fruit in a cool and ventilated place, and remove impurities at the same time; then ultrasonically clean the peaches, at room temperature for 10 minutes, frequency 20KHZ, dry after washing;

[0026] (2) Pre-cooling treatment: The peach is cold-treated within 2 hours after harvesting and pre-treatment. If the fruit temperature is greater than 35°C at this time, the peach is pre-cooled at 20°C for 2 hours, and then the temperature is raised to Refrigerate at 5-7°C for 12-18 hours; if the fruit temperature is less than or equal to...

Embodiment 2

[0035] A method for postharvest preservation, storage and transportation of peach, comprising the following steps:

[0036] (1) Harvesting and pretreatment: In rainless weather, select 8-9 ripe peaches, pick them before 9 am or after 5 pm, keep the stalks, and place them on wooden or plastic cushioning materials. In the turnover box; after picking, remove diseased and insect fruit, softened fruit, deformed fruit, mechanically damaged fruit and defective fruit in a cool and ventilated place, and remove impurities at the same time; then ultrasonically clean the peach, at room temperature for 13 minutes, frequency 22KHZ, dry after washing;

[0037] (2) Pre-cooling treatment: The peach is cold-treated within 2 hours after harvesting and pre-treatment. If the fruit temperature is greater than 35°C at this time, the peach is pre-cooled at 20°C for 2 hours, and then the temperature is raised to Refrigerate at 5-7°C for 12-18 hours; if the fruit temperature is less than or equal to 3...

Embodiment 3

[0046] A method for postharvest preservation, storage and transportation of peach, comprising the following steps:

[0047] (1) Harvesting and pretreatment: In rainless weather, select 8-9 ripe peaches, pick them before 9 am or after 5 pm, keep the stalks, and place them on wooden or plastic cushioning materials. In the turnover box; after picking, remove diseased and insect fruit, softened fruit, deformed fruit, mechanically damaged fruit and defective fruit in a cool and ventilated place, and remove impurities at the same time; then ultrasonically clean the peach, at room temperature for 15 minutes, frequency 25KHZ, dry after washing;

[0048] (2) Pre-cooling treatment: The peach is cold-treated within 2 hours after harvesting and pre-treatment. If the fruit temperature is greater than 35°C at this time, the peach is pre-cooled at 20°C for 2 hours, and then the temperature is raised to Refrigerate at 5-7°C for 12-18 hours; if the fruit temperature is less than or equal to 3...

Abstract

The invention discloses a postharvest fresh-keeping storage and transportation method for peach, belonging to the technical field of edible fruit and vegetable fresh-keeping, storage and transportation. The invention includes the links of harvesting and pretreatment, precooling treatment, spraying of antistaling agent, storage and transportation and the like. In the harvesting stage, ultrasonic technology is used for rapid sterilization; in the preservative spraying stage, double-layer spraying is adopted, and natural antiseptic materials-garlic, cloves and galangal are used to prepare preservatives, which serve as the first protective barrier for peaches. Effectively resist and inhibit the attachment of microorganisms; use natamycin-chitosan composite preservative to spray on the surface of peach again, as an inner layer of preservative, which can delay the aging of peaches and maintain good quality while inhibiting bacteria and preservatives. . The overall process of the invention is simple and easy to operate, and the peach treated according to the process method of the invention can maintain the original quality and flavor of the peach, greatly expand its transportation and sales range, widen the market, and improve economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping, storage and transportation of edible fruits and vegetables, and particularly relates to a method for fresh-keeping, storage and transportation of peach after harvest. Background technique [0002] Mengyin County, Shandong Province, in the central and southern part of Shandong Province, has a temperate monsoon climate with mild climate, four distinct seasons, sufficient sunlight, large temperature difference between day and night, and a long frost-free period, which is especially conducive to the formation of good peach quality, so it is rich in peach. Peach is a deciduous fruit tree belonging to the Rosaceae family, and commonly includes honey peach, nectarine, oil pan peach, pan peach, yellow peach, etc. Peach is the first of the five fruits (peach, plum, apricot, pear, and jujube), known as "longevity peach" and "xiantao". It is juicy, sweet and fragrant. It is not only a good product for...
