Problems solved by technology

In recent years, as people gradually pay more and more attention to the health care of the body, the demand for wild food has increased year by year. During the period, it is easy to cause rot and become inedible; at present, the storage methods used by merchants are: first, vacuum packaging after drying; second, freezing after drying. The above two methods are simple and practical, but the The storage period is generally about 2-3 months at most, and the color and quality of itself cannot be guaranteed for a long time, and the mouthfeel of itself is poor after the storage period, and the nutritional value is also greatly reduced. Therefore, there is an urgent need for a A relatively complete processing method that can prolong the storage period

Embodiment 1

[0033] Example 1. Picking the green leaves around mid-March of each year, remove the rotten leaves, rinse them and place them in a light-transmitting glass shed, keep both sides ventilated, keep the temperature in the shed at 25°C, and leave it for 30 hours to make the product natural Air-dry, and then set aside; then take a certain amount of dandelion into the container, add water at a temperature of 85 ℃, the quality of the added water is 50 times the weight of the dandelion, soak for 60 minutes, then filter to obtain filtrate I, standby; then take a certain amount Put a quantity of green tea leaves into the container, add water at 85℃, soak for 60 minutes, then filter, wash the residue 3 times, combine and shake the filtrate, the main component of this filtrate is tea polyphenols, dilute the filtrate with distilled water A tea polyphenol solution with a tea polyphenol content of 200 mg / L is prepared to prepare filtrate II for use; the filtrate I and filtrate II are mixed acco...

Embodiment 2

[0035] Example 2: Picking the green plants in mid-March of each year, removing the decaying leaves, washing them, and placing them in a 35°C room for 20 hours. Keep the room ventilated to allow the product to air dry naturally for later use; then take a certain amount of dandelion and put it in Into the container, add water at a temperature of 100℃, the quality of the added water is 20 times the mass of dandelion, soak for 30 minutes, and then filter to obtain filtrate I for use; then take a certain amount of green tea leaves into the container, and add the temperature to 100 Soak in water at ℃ for 60 minutes, then filter and wash the residue twice. Combine the filtrate and shake well. The main component of the filtrate is tea polyphenols. Dilute the above filtrate with distilled water to a tea polyphenol content of 40mg / L. Mix the filtrate I and the filtrate II according to the mass ratio of 1:3, and let them stand for 2 minutes to prepare the auxiliary preservation liquid A, w...

Embodiment 3

[0037] Example 3: Picking the saplings around mid-March of each year, removing the decaying leaves, washing them and placing them in a room at 30°C for 25 hours, keeping the room ventilated, allowing the product to air dry naturally, for later use; then take a certain amount of dandelion and put it in Into the container, add water with a temperature of 90℃, the quality of the added water is 40 times the mass of dandelion, soak for 50 minutes, and then filter to obtain filtrate I for use; then take a certain amount of green tea leaves into the container, add the temperature to 90 Soak in water at ℃ for 40 minutes, then filter and wash the residue twice. Combine the filtrate and shake well. The main component of the filtrate is tea polyphenols. Dilute the filtrate with distilled water to a tea polyphenol content of 100mg / L. Mix the filtrate I and the filtrate II according to the mass ratio of 1:3, and let stand for 1.5 minutes to prepare auxiliary preservation liquid A, which is u...

Abstract

A processing method capable of prolonging the storage period of capillary wormwood and retaining its nutritional value. The processing steps are as follows: pick fresh capillary capillary, wash, air-dry, and then prepare auxiliary preservation solution A and auxiliary preservation solution containing dandelion soaking liquid and tea polyphenol liquid B. The air-dried capillary wormwood undergoes the following processing steps in sequence: soak in auxiliary preservative solution A, take out and air-dry, soak in auxiliary preservative solution B, take out and dry; put the dried product into a vacuum fresh-keeping box , Put the fresh-keeping box into the cold room for storage, and the treatment of capillary chennai is completed. In the present invention, through the processing steps of two slow air drying and one fast drying, and soaking in the auxiliary fresh-keeping liquid during the air drying process, the processed product can achieve a storage period of about 12-15 months without reducing the The nutritional value of the product.

Description
