Embodiment 1

[0025] A fresh-keeping method for elm money, the steps are:

[0026] (1) Take fresh peach leaves and mash them into juice, then mix the peach leaf juice with purified water at a mass ratio of 1:85, boil and cool, and cool the temperature to below 25°C for later use;

[0027] (2) Wash fresh elm money, put it in water and heat it, and take it out immediately when the temperature reaches 90°C;

[0028] (3) Put the elm money fished out in step (2) into the peach leaf solution obtained in step (1) and soak for 2 minutes;

[0029] (4) Take out the elm money in step (3) and dry them;

[0030] (5) Sprinkle wheat starch equal in quality to the yuqian evenly on the yuqian, so that all sides of the yuqian are surrounded by starch;

[0031] (6) Store the Yuqian obtained in step (5) at 4°C.

[0032] The yuqian preserved for 25 days in this embodiment has little difference in taste when steamed and eaten with fresh yuqian, but if it is fried and eaten, the taste is not as good as that of...

Embodiment 2

[0034] With embodiment 1, difference is that wheat starch is changed into cornstarch. Step (6) is to store the Yuqian obtained in step (5) at 6°C. The Yuqian preserved for 15 days in this embodiment has the same mouthfeel when steamed and eaten as fresh Yuqian.

Embodiment 3

[0036] With embodiment 1, difference is that wheat starch is changed into cornstarch. Step (6) is to store the Yuqian obtained in step (5) at 2°C. The elm money preserved for 30 days in this embodiment is only compared with the fresh elm money when steamed and eaten, and there is little difference in taste.

Abstract

The invention discloses a fresh-keeping method for the fruit of elm, and belongs to the technical field of food processing. The method comprises the following steps: (1) grinding fresh peach leaves so as to obtain peach leaf juice, then mixing the peach leaf juice with purified water according to a mass ratio of 1:85, boiling the mixed solution, cooling the solution until the temperature of the solution is below 25 DEG C, setting aside for later use; (2) washing fresh fruits of elm, adding into water, heating the water, immediately fishing out the fruits of elm when the temperature of the water reaches 90 DEG C; (3) soaking the fruits of elm fished out in the step (2) into the peach leaf solution obtained in the step (1) for 2 minutes; (4) fishing out the fruits of elm in the step (3), drying; (5) spraying starch with the same weight as that of the fruits of elm on the fruits of elm so as to wrap each surface of the fruits of elm; (6) preserving the fruits of elm obtained in the step (5) at a temperature of 2 to 6 DEG C. The fresh-keeping method can preserve fruit of elm for 30 days, largely exceeds the prior art, and furthermore, the preserved fruit of elm has a similar taste as that of the fresh fruit of elm.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a fresh-keeping method for elm money.
