Problems solved by technology

These three types of methods all have their advantages and disadvantages. Although the first type of sand-buried fresh-keeping method is an effective and non-toxic and safe fresh-keeping method, it is difficult to realize on a large scale in industry at present; The most widely used method on a large scale, but the chestnuts that have deteriorated inside cannot be removed before the chestnuts are stored, which takes up unnecessary storage space. Once insects and mildew rot, it will also affect other chestnuts, and the fruit will be damaged during storage. The ratio is relatively high; the fresh-keeping method of the third type of chemical agent treatment cannot be said to be a very safe method of fresh-keeping chestnuts

Embodiment Construction

[0014] Use manual or mechanical means to evenly destroy the shell structure of the chestnut, so that the structure of the chestnut shell is destroyed without harming the chestnut kernel inside, and then quickly quenched with cold water, so that the damage on the chestnut shell is affected by stress such as temperature difference The bottom is opened, and the chestnut shell and chestnut underwear around the opening are separated from the chestnut kernel, so that the color protection liquid can be in contact with the chestnut kernel. Chestnuts can also be shelled into chestnut kernels by mechanical means.

[0015] Soak for 20 minutes in the color-protecting solution at 90 DEG C. The proportioning of the color-protecting solution is: water 96.5% (weight %), food-grade disodium EDTA 0.3%, food-grade citric acid 0.2%, and salt 3%. The chestnut or chestnut kernels are conveyed by crawlers through a long stainless steel pool filled with color protection solution, and the conveying sp...

Abstract

A high-safety antistaling storage method for chesnut includes such steps as scratching to make a seam on its shell, controlling surface temp, heating for a certain time to crack it, removing poor ones, ultraviolet sterilizing, rinsing, loading in bag, filling inertial gas, and storing at -3-5 deg.C.

Description

technical field [0001] The invention belongs to the technical field of agricultural product storage in food engineering, and in particular relates to a method for storing Chinese chestnuts, in particular to a method for safely storing and keeping fresh Chinese chestnuts. Background technique [0002] The storage and preservation of chestnut is also one of the key technologies restricting the large-scale development of chestnut resources. The chestnut farmers in the vast chestnut-producing areas are often confused by the increase in chestnut production. A large number of chestnuts with increased production must be sold within a short period of time. Worms or mildew and discoloration caused heavy losses, so when the production increased, they bargained with each other to sell chestnut raw materials, which led to a confusing situation of increasing production but not increasing income. The fundamental reason is that the industrialization of chestnut prese...
