Embodiment 1

[0045] A processing method of nutritious jujube preserves, comprising the following steps:

[0046] (1) Pretreatment: select mature, fresh red dates without mildew, wash, dry, take 20 parts by weight of dried red dates and add 80 parts by weight, and the temperature is 85 ℃ water and scald for 15 seconds;

[0047] (2) Color protection: put the red dates in step (1) into 100 parts by weight of the color-protecting fresh-keeping solution and immerse them for 30 minutes. The dipping temperature is 45° C., remove the red dates, and dry the red dates at 40° C. for 30 minutes;

[0048] (3) sugar infiltration: the red dates of step (2) are added in 150 parts by weight of sugar infiltration liquid, and microwave infiltration in sugar is carried out. The method of microwave infiltration in sugar is: microwave heating with a frequency of 2450MHz and a power of 500W for 5 times, each microwave The heating time is 40s, stop heating for 5 minutes, and then carry out the next microwave heat...

Embodiment 2

[0053] It is basically the same as Example 1, the only difference being that the step (3) sugar infusion described in the present embodiment 2 is: the red dates in step (2) are added in 150 parts by weight of the sugar infusion solution, and microwave infusion of sugar is carried out. The method is: use a microwave with a frequency of 2450MHz and a power of 300W to heat 5 times, each time the microwave heating time is 40s, stop heating for 5min, and then perform the next microwave heating, cool to 30°C after microwave sugar infiltration, and keep warm at 30°C for 2 Hour.

Embodiment 3

[0055] It is basically the same as Example 1, the only difference being that the step (3) sugar infusion described in the present embodiment 3 is as follows: the red dates in step (2) are added in 150 parts by weight of the sugar infusion solution, and microwave infusion of sugar is carried out. The method is: use a microwave with a frequency of 2450MHz and a power of 800W to heat 5 times, each microwave heating time is 40s, stop heating for 5min, and then carry out the next microwave heating, cool to 30°C after microwave sugar infiltration, and keep warm at 30°C for 2 Hour.
