Problems solved by technology

[0004] (1) The time of cooking and cold shock is too long, which will cause the jujube skin to break, shrink in different degrees, and have uneven fine lines
[0005] (2) The traditional hot smoking temperature is 120°C-150°C. The high temperature causes the nutrients in the jujube to decompose, and the finished jujube is not strong in aroma and smoke

Embodiment 1

[0065] A smoked jujube, comprising the following components:

[0066] Jujube after cold shock, compound smear microcapsules.

[0067] The preparation steps of jujube after the cold shock are as follows:

[0068] ⑴Raw material selection

[0069] Select fresh jujubes without insects, damage and cracks as raw materials;

[0070] ⑵Sterilization

[0071] Pick jujubes with uniform quality, clean and classify them, and wash them with high-pressure air tumble. The cleaning solution is an aqueous solution of chloric acid. Wash for 10-20min and set aside;

Abstract

The invention discloses fumigated jujubes. The fumigated jujubes comprise the following components: cold-shock jujubes and compound smearing microcapsules. The fumigated jujubes comprise the cold-shock jujubes and the compound smearing microcapsules. The cold-shock jujubes are subjected to pulse electric field boiling and ultrasonic cold shock during preparation, so that the jujube skin is purplein color, thin, shallow and uniform in wrinkles and complete in appearance, and the pulp is elastic. The compound smearing microcapsules not only strengthen the metal nutrient elements such as calcium, iron, zinc and selenium, but also strengthen non-metallic nutrient elements such as fat, dietary fibers, vitamins and amino acids, and simultaneously enhance the jujube flavor of the product. The fumigated jujubes are rich in nutrients, and the fumigated jujubes also enrich food variety, and greatly meet the requirements of consumers.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a smoked jujube and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living standards, people's requirements for food are getting higher and higher and more diverse, and the existing food types can no longer meet the needs of consumers. [0003] Smoked jujube is made from cooked and fresh red dates, which are boiled, kiln-smoked, and shaded. There are following problems when making smoked dates in the prior art: [0004] (1) The time of cooking and cold shock is too long, which will cause the jujube skin to break, shrink in different degrees, and have uneven fine lines. [0005] (2) The temperature of traditional hot smoking is 120°C-150°C. The high temperature causes the nutrients in the jujube to decompose, and the finished jujube is not strong in fragrance and smoke. [0006] Through searching, the following se...
