Embodiment 1

[0017] 1. Prepare a post-harvest edible preservative for peach fruit, which is composed of rhamnolipid and limonene, and the concentration of the working solution used is 0.5% (v / v) of rhamnolipid and 100 mg / L of limonene;

[0018] 2. Use edible preservatives for peach preservation:

[0019] (1) When the peach fruit is harvested, pick it gently to avoid damage;

[0020] (2) Select the picked fruit, select the fruit with uniform size, no disease, no damage;

[0021] (3) The edible preservative is sprayed and sprayed on the peach fruit for 60 seconds;

[0022] (4) The treated fruit is dried and stored under a suitable temperature condition.

Embodiment 2

[0024] The peach fruit used in the experiment is a hard peach. The fruit material was collected in Linyi City, Shandong Province in October 2019. After harvest, the fruit with uniform size, no mechanical damage, and no pests and diseases was selected. After being treated with different preservatives, it was transported back to Zhejiang the next day The Fruit Tree Science Research Institute of the College of Agriculture and Biotechnology of the University carries out storage (10°C, RH 90-95%), and the composition and concentration of the antistaling agent formula are as follows:

[0025] Treatment A: directly put into storage after harvesting;

[0026] Treatment B: 0.5% modified pectin + 0.5% rhamnolipid, atomized and sprayed on the fruit surface, dried and stored in warehouse;

[0027] Treatment C: Natamycin 100mg / L + rhamnolipid 0.5%, atomized and sprayed on the fruit surface, dried and stored in warehouse;

[0028] Treatment D: Limonene 100mg / L + rhamnolipid 0.5%, atomized ...

Embodiment 3

[0039] As the storage time prolongs, the fruit will gradually rot. The rot rate is a direct reflection of the effect of fruit storage and preservation. The experimental results show that among the six treatments of A, B, C, D, E and F, edible preservative formulations B, C, D, and F can significantly reduce the rot rate of peach fruit compared with the fruit of the control group A ; On the 70th day of peach storage, seven groups of fruit rot rates were respectively 15%, 5%, 10%, 2.5%, 10%, 7.5% compared to A and edible preservatives, wherein, treatment group D (0.5 %rhamnolipid+100mg / L limonene) the lowest decay rate (see figure 1 ).

Abstract

The invention provides an edible fresh-keeping agent for honey peach fruits after harvest, and an application of the edible fresh-keeping agent. The edible fresh-keeping agent is composed of two components rhamnolipid and limonene. The selected fruits are treated by spraying the fresh-keeping agent before storage, and then are stored at an appropriate temperature. The edible fresh-keeping agent solves the problem of the rotting of the honey peach fruits during long-term storage, effectively reduces a fruit rotting rate, maintains the good quality and commerciality of the stored fruits, prolongs the fruit storage time, and can be applied in the fresh-keeping of hard honey peach fruits. The method of the invention has simple and convenient operation and relatively low equipment requirements,the quality loss of the stored fruits is low, the storage effect is good, and the formula components are food sources, so that the fruit safety and quality are ensured, and thereby the edible fresh-keeping agent can be operated on a large scale, and demonstrated and promoted and applied.

Description

technical field [0001] The invention belongs to a fruit storage and fresh-keeping method, and relates to an edible fresh-keeping agent for post-harvest peach fruits and an application thereof. Background technique [0002] Peach has a complete color, fragrance, shape and high nutritional value. It is one of the main fruits in my country. However, peach fruit is thin and sweet and juicy, so it is not resistant to storage and transportation. Honey peaches are susceptible to various diseases during post-harvest storage and transportation, and the fruit is extremely easy to rot. Postharvest preservative treatment is a commonly used preservation strategy in many fruits. However, since peach fruits are generally eaten with their skins, commonly used agricultural fungicides are seldom used in peach fruits. Therefore, looking for edible green and safe preservative ingredients is one of the important ways to improve the postharvest fresh-keeping effect of peach fruits. Contents ...
