Embodiment 1

[0038] The present embodiment provides a kind of Amethyst jujube processing technology, and described processing method comprises:

[0039] (1) Precooking: sorting fresh red dates, precooking them in water at 90°C for 2 minutes to obtain seven-ripe precooking dates, said fresh red dates being those planted within 2 kilometers from the banks of the Yellow River;

[0040] (2) Cooling: cooling the precooked jujube obtained in step (1) in clear water at 30°C for 2 minutes, taking it out and cooling to room temperature to obtain the cooled jujube;

[0041] (3) Drying: the cooled jujube obtained in step (2) was dried at 50°C for 24 hours to obtain the dried jujube with a water content of 40%. The product is not subject to high pressure; at the same time, heating is used to dry it in batches to ensure that the product structure is not damaged and the original flavor is not damaged;

[0042] (4) Drying: the dried jujube obtained in step (3), after cooling for 48 hours, obtains the dr...

Embodiment 2

[0045] The present embodiment provides a kind of Amethyst jujube processing technology, and described processing method comprises:

[0046] (1) Precooking: sorting the fresh red dates, precooking them in 100°C water for 10 minutes to obtain seven-ripe precooked dates, the fresh red dates being those planted within 2 kilometers from the banks of the Yellow River;

[0047] (2) Cooling: cooling the precooked jujube obtained in step (1) in clear water at 50°C for 10 minutes, taking it out and cooling to room temperature to obtain the cooled jujube;

[0048] (3) Drying: the cooled jujube obtained in step (2) was dried at 80°C for 30 hours to obtain the dried jujube with a water content of 40%. The product is not subject to high pressure; at the same time, heating is used to dry it in batches to ensure that the product structure is not damaged and the original flavor is not damaged;

[0049] (4) drying: the dried jujube obtained in step (3) is cooled and sunned for 96 hours to obta...

Embodiment 3

[0052] The present embodiment provides a kind of Amethyst jujube processing technology, and described processing method comprises:

[0053] (1) Precooking: sorting fresh red dates, precooking them in 95°C water for 3 minutes to obtain precooked dates, said fresh red dates being those planted within 2 kilometers from the banks of the Yellow River;

[0054] (2) Cooling: cooling the precooked jujube obtained in step (1) in clear water at 35°C for 38 minutes, taking it out and cooling to room temperature to obtain the cooled jujube;

[0055] (3) Drying: the cooling jujube obtained in step (2) was dried at 65° C. for 24 hours to obtain the dried jujube with a water content of 40%. The product is not subject to high pressure; at the same time, heating is used to dry it in batches to ensure that the product structure is not damaged and the original flavor is not damaged;

[0056] (4) Drying: the dried jujube obtained in step (3), after cooling for 60 hours, obtains the dried jujube;...

Abstract

The invention relates to an amethystine jujube processing technology. The amethystine jujube processing technology takes red jujubes in the yellow river beach as a raw material and comprises five steps of precooking, cooling, drying, airing and secondary drying. Compared with the prior art, the amethystine jujube processing technology has the following beneficial effects: (1) the amethystine jujube processing technology is simple, convenient to operate and low in process cost, the taste of a product is greatly improved by precooking treatment and secondary drying technologies, and the amethystine jujube product is stable in texture and suitable for industrial production; (2) third-party detection shows that the heavy metal content, the pesticide residue, the food additive content and the bacterial content of the amethystine jujube product obtained with the amethystine jujube processing technology meet the requirements of NY / T1041-2018 Green Food Dried Fruit.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a processing technology of jujube products, in particular to a processing technology of amethyst jujube. Background technique [0002] Jujube is a nutritious food, especially the jujube located on the Yellow River beach. It has thin skin, large fruit, high sugar content, and soft and glutinous taste. It has the effects of nourishing yin and yang, nourishing blood, and has high medicinal value. [0003] Due to the thin skin of the jujube on the Yellow River Beach, it has poor storage and transportation capacity, so it can be made into jujube products. On the one hand, it can retain the nutrition of the jujube to the greatest extent, and at the same time, it has greatly promoted the local economic development. [0004] Most of the present jujube products are candied dates, which have a good taste and taste and are favored by consumers. The existing preparation process of can...
