Embodiment 1

[0010] Sorting the fresh dates to remove immature and damaged dates, cleaning the sorted dates, draining the water after cleaning, then putting the dates in the oven, setting the temperature of the oven to 85°C, taking it out after 15 minutes, cooling down or No need to cool down. Finally, seal them in a plastic bag and store them in a cold storage with a temperature of -2°C. After 12 months of storage, the weight loss rate is less than 1%, and the fruit rot rate is less than 3%.

Embodiment 2

[0012] Sorting the fresh dates to remove immature and damaged dates, cleaning the sorted dates, draining the water after cleaning, then putting the dates in the oven, setting the oven temperature to 95°C, taking it out after 25 minutes, and cooling It can be cooled down, and finally sealed with a plastic bag and put into a cold storage. The temperature of the cold storage is set at -5°C and stored for 12 months. The weight loss rate is less than 1%, and the fruit rot rate is less than 1%.

Embodiment 3

[0014] Sorting fresh jujubes to remove immature or damaged jujubes, cleaning the sorted jujubes, putting the jujubes in a boiling water pot for 5 minutes after cleaning, then taking the jujubes out, ventilating and draining the water for 10 minutes at 5°C, and finally packing The plastic bag is sealed into the cold storage, and the temperature of the cold storage is set to -2°C. After 12 months, the weight loss rate of jujube is less than 2%, and the fruit rot rate is less than 3%.

Abstract

The storing process of date as date juice material includes sorting and cleaning, high temperature sterilizing, packing and freezing, and features that cleaned date is sterilized at 85-100 deg.c for 10-25 min, sealed in plastic bag and maintained in cold storage warehouse at the temperature of -2 to -5 deg.c. The said technological scheme makes it possible for to prolong the date preserving period to over 12 months with less nutrients loss and the preserved date may be used in producing date juice beverage with the taste and nutrients similar to that of fresh date.

Description

technical field [0001] The invention relates to a storage method of jujube fruit, in particular to a storage method of jujube fruit used as a raw material of jujube juice. Background technique [0002] As a kind of fruit, jujube has a sweet taste and crisp meat, rich in nutrients such as multivitamins and trace elements needed by the human body, and has both edible and medicinal effects. In order to meet the needs of consumers, the technology of deep processing jujube into jujube juice drinks and other products has been continuously developed. Jujube juice processing requires a lot of fresh raw materials to ensure its continuous production, but jujube fruit has a strong seasonality and is not suitable for off-season planting, so how to preserve the fruit in the high-yield season until the next year's high-yield season is relatively difficult question. Existing technology has many fresh-keeping technologies for fruit or jujube fresh fruit. The comm...
