Can fresh jujubes be preserved by freezing? Methods for preserving fresh jujubes

Fresh jujubes can be frozen. Frozen jujubes can be used to make fruit salad or to cook porridge; they are not only crisp in texture but also fresh and sweet, and even after the jujube season has passed you can still eat fresh jujubes to supplement vitamins.

How to freeze and preserve fresh jujubes

1. For fresh jujube preservation, you must first choose a good date for picking the fresh jujubes; pick them when the red fruit has reached more than 25% coloring, as red jujubes at this stage store best.

2. The picked fresh jujubes also need to be sorted; remove the bad jujubes with bruises on the surface or with black spots and insects, so that during storage moldy bad jujubes do not infect the other jujubes and affect storage.

3. Fresh jujube preservation generally uses cold storage; before refrigerating, first pre-cool the fresh jujubes to be stored at a temperature of 5-8°C for one or two days. Before pre-cooling, soak the fresh jujubes in a 2% calcium chloride solution for 30 minutes.

4. After pre-cooling, place the fresh jujubes in a cold storage room at a temperature of 0°C-1°C and a relative humidity of 90%-95% for storage.

How to choose fresh jujubes

1. Look at the peel. The peel of high-quality winter jujubes is purplish red or dark red, the grains are fairly uniform in size, there are few wrinkles, the skin is thin, and the flesh is thick and fine. If you see many wrinkles on the fresh jujubes, they may be not fresh or of poor quality, so do not buy those.

2. Look at the jujube stem end. If the stem end of the fresh jujube has a red or dark red ring, it shows that it received sufficient sunlight, so the quality is certainly better; and if the color at the stem end is natural with no obvious red-green boundary line, it shows that the fresh jujube ripened naturally and was not artificially ripened, so of course this kind can be bought.
