The normally dried red dates are bright and natural in color, while the red dates soaked in saccharin sodium are dim or even over-dividend, and have no luster. In addition, the surface of soaked jujube is very soft, without the compactness of dried fruit, and it is not durable. After a few days, it will wrinkle and even separate the pulp.

Third, the normal growth of jujube pulp has high sugar content, the peel is not sweet, and even bitter. Jujube soaked in sugar is sweet outside and bitter inside.

Therefore, to sum up, we can identify whether jujube has been soaked in sugar water by observing the color and taste of jujube.

Storage method of jujube:

Northern storage method

In mass storage, sacks are used for palletizing storage. When palletizing, there should be ventilation gaps between bags and stacks to facilitate ventilation. The wall is a little damp. Don't pile it too close to the wall.

Southern storage method

The southern region is hot and humid, and should be refrigerated in summer and mildew season. Jujube is packed in gunny bags and stored in a warehouse at 5℃. Before leaving the cold storage, it should be moved to a slightly higher temperature for transition and gradually moved out of the warehouse. In order to prevent water vapor from condensing into water droplets on jujube fruit, do not repackage it immediately, but spread it out to dry, and then change bags and package it for shipment after the condensed water droplets disappear.

A small amount of red dates can be stored with rice husk ash. Dry rice husk, with a thickness of about 1 cm, with a layer of red dates, covered with rice husk ash and covered with red dates. This storage method can prevent moisture, sterilize and dry jujube particles, and the effect is good.
