Problems solved by technology

At present, there are limited good varieties of red-fleshed peaches used in cultivation and production. The accumulation of pigments in the pulp varies under different climatic conditions and cultivation methods, which is prone to the problem that the characteristics of red flesh are not prominent.
Especially in extreme cases, premature picking leads to the failure of high-level synthesis, transformation and accumulation of pigment substances, which will easily cause most of the red-flesh peaches to turn white, causing consumers to doubt the authenticity of the red-flesh peaches they buy. Doubts affect brand reputation

Embodiment 1

[0015] Red-fleshed peaches were planted in the experimental and demonstration production garden of Pinghu Town, Gutian County, Fujian Province. This variety blooms in the middle and late February locally, matures at the end of May and early June, and the flesh is bright red. In June 2020, select continuous sunny days, concentrate on picking seven-ripe peach fruits, and select non-harmful fruits, and randomly divide them into two groups (control group and experimental group) for comparative experiments.

[0016] Experimental group: Put the fruit into the holding box with the tip of the fruit facing down and the bottom of the fruit facing up, such as figure 1 Shown, air cooling cooling. Thereafter, the crate and the peach fruit were sent to the cold storage at 10°C for 16 hours, and the fruit was treated with vertical light using an agricultural tungsten halogen lamp (the light intensity at the bottom of the fruit was determined to be 5000 lux at this time). After 16 hours, th...

Embodiment 2

[0024] Red flesh peaches are grown in the peach production garden of Dahu Township, Minhou County, Fujian Province. This variety blooms locally in early March and matures in mid-June. In June 2020, select continuous sunny days to pick seven-ripe peach fruits intensively, and conduct treatment and investigation according to the same scheme as in Example 1. Relevant data also confirmed that the fruit red color of the treatment group was deeper and more obvious. The relevant data of color difference measurement are as follows in Table 2:

Abstract

The invention discloses a postharvest treatment method for improving conversion and accumulation of natural pigment substances of red-pulp peaches. The method comprises the following treatment steps of (1) picking 70% maturity healthy fruits according to the actual growth and development process of different varieties of red-pulp peach fruits while keeping away from rainy days or high-temperaturehumid weather after raining, (2) after picking, putting the fruits in an environment at a temperature of 6-10 DEG C with the fruit tips facing downwards and the fruit bottoms facing upwards for precooling treatment for 12-24 hours, and synchronously using a light source not less than 3000lux for illumination treatment in the precooling treatment process, and (3) boxing the treated fruits for transportation, and controlling the transportation period and the shelf life temperature of the fruits between 22 DEG C and 28 DEG C. After the method disclosed by the invention is used for treating the 70%-mature red-pulp peach fruits, the quality and flavor of the fruits are not influenced, the synthesis of related pigment precursor substances in pulp is accelerated, the conversion and accumulation levels are higher, the pulp red color is more obvious, the pulp red color fading problem is alleviated, the method is safe and reliable, and the required investment fund is less.

Description

technical field [0001] The invention belongs to the technical field of fruit tree production, and in particular relates to a method for enhancing the accumulation of red-flesh peach fruit pigment substances. Background technique [0002] Red flesh peach is a rare peach germplasm resource. In the long-term production practice, people discovered and preserved the red flesh peach resources with local characteristics, which became the beginning of modern red flesh peach breeding and production. In a broad sense, red-flesh peach varieties refer to peach varieties with obvious red flesh when the fruit is ripe. The degree of redness of the flesh is directly related to the accumulation of pigment substances in the flesh. At present, the number of good varieties of red-fleshed peaches used in cultivation and production is limited, and the accumulation of pulp pigments varies under different climatic conditions and cultivation methods, which is prone to the problem that the character...
