Problems solved by technology

And adopt above fresh-keeping method, although there is certain fresh-keeping effect, there are some problems in different degrees: the loss of nutrients is more, easy to lose water, appearance changes, mouthfeel is relatively poor, in addition, eat fresh jujube raw, although can be more fresh. Keep more vitamin C and vitamin P in fresh dates, so as to improve the function of capillary walls and help eliminate bleeding spots or ecchymosis on the skin; bad people especially not suitable
[0004] For cooked dried dates, fresh dates are called dried dates after dehydration and drying. Compared with fresh dates, dried dates have a longer shelf life. The nutritional value of jujube is low, and its water content is also low, compared with fresh jujube, the taste is not good

Embodiment 1

[0047] A processing technology of quick-frozen fresh jujube includes the following steps:

[0048] 1. Raw material grading: transport the raw jujube into the grading room, turn on the switches of the winnowing machine and the grading machine, and manually load the materials to the winnowing machine. The fruit is used to remove impurities such as weeds and leaves. After the selection, the fruit automatically enters the grading stage, and the fruit is graded through the first to fifth graders, and a receiving hopper is placed at the outlet of each level;

[0049] 2. Raw material cleaning: turn on the switches of the air flotation cleaning machine, brush cleaning machine and air flotation cleaning machine, and open the water inlet valves of the three cleaning machines at the same time, and manually feed the materials to the hopper of the elevator, and transport the fruits to the elevator through the elevator The first washing machine cleans, and then the fruit passes through the water...

Description

Technical field [0001] The invention belongs to the field of food processing, and specifically relates to a processing technology of quick-frozen fresh dates. Background technique [0002] Chiping round bell jujube originated in the Xiaozhuang area of ​​Chiping County, Shandong Province. It has a long historical record. It is a traditional local product of Chiping and a geographical indication product of Chiping. At present, the processing of Yuanling jujube mainly includes the production of fresh-keeping dates, black dates, dried dates, date drinks, candied dates, etc. [0003] The preservation and storage of jujube has always been a difficult technical problem. At present, the commonly used methods of jujube preservation include the following: normal temperature wet sand storage, spontaneous modified atmosphere storage, frozen storage preservation, low-temperature storage, and small-package airtight storage. Although the above preservation methods have a certain preservation ef...
