Problems solved by technology

In the prior art, when chlorine dioxide is used to keep fruits and vegetables fresh, most of them use solutions to soak fruits and vegetables or add solid slow-release agents in the packaging. However, if liquid chlorine dioxide is used to soak fruits and vegetables, it will seriously affect the quality of fruits and vegetables. External quality, and it needs to be dried after soaking, which increases the process and is time-consuming and laborious; if a chlorine dioxide solid sustained-release agent is used, the release time of the solid sustained-release agent is often longer, and the distribution generally takes 1 to 2 hours. Complete within days, high cost and poor applicability

Embodiment 1

[0025] The present embodiment carries out delivery fresh-keeping to tomato, comprises the following steps:

[0026] (1) Put the tomatoes into the pre-cooling room for pre-cooling within 2 hours after picking, and the pre-cooling temperature is 2-5°C;

[0027] (2) Tomatoes are put into boxes or boxes when they leave the warehouse. The volume of the box or box is 33L. Polypropylene fiber material with polyethylene backing, under the packaged state, the side with polyethylene backing on the fresh-keeping pad is in contact with the tomato; the amount of liquid chlorine dioxide adsorbed in the fresh-keeping pad is m=0.301g / L×V box= 0.301×33=9.933g

[0028] In the formula: m is the mass of adsorbed liquid chlorine dioxide, g;

[0029] V box is the volume of the box or box, L;

[0030] (3) Cover the box or box cover well and deliver at room temperature.

Embodiment 2

[0045] In this embodiment, the fresh-keeping of vegetables is carried out, including the following steps:

[0046] (1) After the green vegetables are picked, put them into the pre-cooling room for pre-cooling within 2 hours, and the pre-cooling temperature is 2-5°C;

[0047] (2) Packing or packing the vegetables out of the warehouse. The volume of the packing box or packing box is 33L. Polypropylene fiber material with polyethylene backing, when the packaging is completed, the side of the fresh-keeping pad with the polyethylene backing is in contact with the vegetables; the amount of liquid chlorine dioxide adsorbed in the fresh-keeping pad is

[0048] V=0.0001×V box=0.0001×33×1000=3.3mL

[0049] In the formula: V is the volume of adsorbed liquid chlorine dioxide, mL;

[0050] V box is the volume of the packing box (box), mL;

[0051] (3) Cover the box or box cover well and deliver at room temperature.

Abstract

The invention relates to a fresh-keeping method for fruit and vegetable delivery. The invention uses dew condensation on vegetables and fruits combined with chlorine dioxide to keep vegetables and fruits fresh, and pre-cools the fruits and vegetables after picking, so that dew condensation will occur when the fruits and vegetables leave the warehouse and return to room temperature, and the dew will Evenly spread on the surface of fruits and vegetables; at the same time, the chlorine dioxide in the fresh-keeping pad gradually volatilizes at room temperature, and the vaporized chlorine dioxide quickly dissolves in the condensation on the surface of the fruits and vegetables, so that not only can the condensation be used to replenish water for the fruits and vegetables, but also prevent the fruits and vegetables from wilting, and the dew dissolved in chlorine dioxide can kill bacteria and other microorganisms on the surface of fruits and vegetables, and maintain the quality of fruits and vegetables; moreover, if the chlorine dioxide solution is directly sprayed on fruits and vegetables, it is not easy to spray evenly on the one hand, and on the other hand, the fruits and vegetables will not Condensation will occur after storage, and spraying chlorine dioxide solution at this time will cause the surface of vegetables and fruits to be too wet, which will affect the freshness quality of vegetables and fruits; and the dew condensation of the present invention is uniform and delicate, and can be evenly covered on the surface of vegetables and fruits after dissolving chlorine dioxide, which has a good freshness preservation effect. it is good.

Description

【Technical field】 [0001] The invention relates to a delivery and preservation method for fruits and vegetables, in particular to a delivery and preservation method for non-cold-sensitive fruits and vegetables. 【Background technique】 [0002] With the continuous improvement of social living standards, fruit and vegetable distribution has quietly entered thousands of households and has become a new way of life in the Internet + era. The situation is worrying, and there are often problems such as dehydration, wilting, rotting, and peculiar smell of fruits and vegetables. Due to limited social resources, it is often difficult to realize the whole process of cold chain distribution. Enterprises with conditions can pre-cool before distribution, which maintains the quality of distribution to a certain extent. However, dew condensation often promotes the growth of microorganisms and accelerates the recovery of fruits and vegetables after they are warmed up. corruption. [0003] St...
