Abstract

The invention relates to the technical field of vegetable fresh-keeping processing methods, especially relates to a fresh-keeping processing method for green bamboo shoots. The method can enhance fresh-keeping effects effectively. The method comprises the following steps: washing: green bamboo shoots are washed in a washing device; beheading and grading: thick and old green bamboo shoots are beheaded in a manual way, the other parts are cut apart and grading of good green bamboo shoots and inferior green bamboo shoots is carried out; cooling: a basket is placed in a cooling tank, the cooling tank is communicated with an ice water storage tank, ice water is transported to the cooling tank from the ice water storage tank through a water pump and then flows into the ice water storage tank until the center temperature of the green bamboo shoots is lowered to 0 DEG C; packaging: the green bamboo shoots are placed in a foam box, and ice bags are placed in the foam box; cold store preservation: the box with the green bamboo shoots and the ice bags are placed in a cold store with a relative humidity of 80%-90% and a temperature of 0-5 DEG C for preservation.

Description

Dendrocalamopsis oldhami processing method for keeping fresh

Technical field

The present invention relates to the processing method technical field of fresh-keeping of vegetables, particularly relate to a kind of Dendrocalamopsis oldhami processing method for keeping fresh.

Background technology

As everyone knows, Dendrocalamopsis oldhami is tender and crisp, fresh and sweet tasty and refreshing because of tasty mouthfeel, and unique flavor, is the fine work in bamboo shoot; But due to term of Dendrocalamopsis oldhami during the broiling summer, so the antistaling storing of Dendrocalamopsis oldhami is very difficult, general Dendrocalamopsis oldhami is adopted latter two hours local flavors and will be started variation, and be accompanied by aging fast, fiber increases, so eat or process the fresh-keeping problem that Dendrocalamopsis oldhami all faces raw material raw, the product of conventionally eating raw is edible in 6 hours after gathering under 25~30 ℃ of conditions, and flavor variations is little.Under normal temperature, storage is within 1 day, being just decline greatly of marketing quality.For a long time because preservation and freshness difficulty is large, long-distance transport export trade is difficult, and its production development has been subject to very large impact, and existing preservation technique or be to use chemical method causes the fresh and sweet taste of Dendrocalamopsis oldhami to be affected; Be exactly by canning, pickle and drying supply phase and the expansion extent of supply of extending, but these methods have all reduced intrinsic local flavor and the nutritive value of bamboo shoot body to a certain extent, because of the just bad change of quality of first being processed raw material, finished product is also affected simultaneously.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of Dendrocalamopsis oldhami processing method for keeping fresh of effective enhancing fresh-keeping effect.

Dendrocalamopsis oldhami processing method for keeping fresh of the present invention, comprises the following steps:

1), clean, adopt cleaning device to clean the Dendrocalamopsis oldhami gathering;

2), the classification of choping off the head, after Dendrocalamopsis oldhami cleans, adopt manual type that thick old Dendrocalamopsis oldhami head is struck off, and all the other departments cut and carried out Dendrocalamopsis oldhami and time Dendrocalamopsis oldhami classification, after good Dendrocalamopsis oldhami and inferior Dendrocalamopsis oldhami are put into respectively to different basketrys;

3), cooling, the basketry that has been placed with Dendrocalamopsis oldhami and time Dendrocalamopsis oldhami is put into cooling tank, cooling tank communicates with frozen water storage pool and by water pump, frozen water is flowed in frozen water storage pool after frozen water storage pool is delivered to cooling tank again, form circulation, until Dendrocalamopsis oldhami central temperature drops to 0 ℃ to 5 ℃;

4), packing, the Dendrocalamopsis oldhami after cooling is put into the bubble chamber with polyethylene film lining bag, and in bubble chamber, puts into ice bag;

5), freezer preserves, and by putting into the bubble chamber of Dendrocalamopsis oldhami and ice bag to relative humidity, is that 80%-90%, temperature are that the freezer of 0-5 ℃ is preserved.

Dendrocalamopsis oldhami processing method for keeping fresh of the present invention, step 4) described in, the weight of ice bag is the 10%-20% of Dendrocalamopsis oldhami weight.

Dendrocalamopsis oldhami processing method for keeping fresh of the present invention, described cleaning device is radish automatic rinser.

Compared with prior art beneficial effect of the present invention is: setting steps cleans-chops off the head classification-cooling-packing-freezer and preserves several steps, like this, can carry out Dendrocalamopsis oldhami cooling by frozen water processes, only need about 30 minutes, in cooling processing procedure, effectively reduced the injury to Dendrocalamopsis oldhami, thereby better reached fresh-keeping effect, ultimate guarantee the quality of Dendrocalamopsis oldhami.

The specific embodiment

Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.

Dendrocalamopsis oldhami processing method for keeping fresh of the present invention, comprises the following steps:

1), clean, adopt cleaning device to clean the Dendrocalamopsis oldhami gathering;

2), the classification of choping off the head, after Dendrocalamopsis oldhami cleans, adopt manual type that thick old Dendrocalamopsis oldhami head is struck off, and all the other departments cut and carried out Dendrocalamopsis oldhami and time Dendrocalamopsis oldhami classification, after good Dendrocalamopsis oldhami and inferior Dendrocalamopsis oldhami are put into respectively to different basketrys;

3), cooling, the basketry that has been placed with Dendrocalamopsis oldhami and time Dendrocalamopsis oldhami is put into cooling tank, cooling tank communicates with frozen water storage pool and by water pump, frozen water is flowed in frozen water storage pool after frozen water storage pool is delivered to cooling tank again, form circulation, until Dendrocalamopsis oldhami central temperature drops to 0 ℃ to 5 ℃;
