Embodiment 1

[0037] Step 1. Pretreatment: Select fresh and healthy fresh and healthy red dates that are free from pests, mildew and rot, after cleaning, wipe off the surface moisture, and cut into fresh jujube slices less than or equal to 1mm;

[0038] Step 2. Flavoring: Weigh red jujube slices, equivalent to 100g in dry weight, put them into an electric oven and bake at 100 degrees Celsius for 3 hours.

[0039] Step 3, dissolving aroma: adding the dried jujube slices in step 2 to the dehydrated ethanol solution at -15 degrees Celsius at a dry weight ratio of 1g:10mL, and stirring for 25min to extract and dissolve the aroma. The temperature of cold absolute ethanol is -20~-10 degrees Celsius;

[0040] Step 4. Extraction: Add 300ml of demineralized water and 50mL of absolute ethanol to the material liquid after extracting and dissolving fragrance in step 3. At this time, the mass concentration of ethanol in the extraction liquid is 80%, and the ratio of material to liquid is 1:15 , carry o...

Embodiment 2~37

[0044] Except that the baking temperature and time described in the step 2 flavoring are different from Example 1, all the other are the same as Example 1.

[0045] The baking temperature and time used in Examples 2-37 are shown in Table 1.

[0046] The baking temperature and time that table 1 embodiment 2~37 adopts respectively

Embodiment 38

[0049] Step 1. Pretreatment: Select fresh and healthy fresh and healthy red dates that are free from pests, mildew and rot, after cleaning, wipe off the surface moisture, and cut into fresh jujube slices less than or equal to 1mm;

[0050] Step 2, aromatization: Weigh the jujube slices, equivalent to 100g in dry weight, put them into an electric oven and bake at 100 degrees Celsius for 4 hours;

[0051] Step 3, dissolving fragrance: adding the dried jujube slices in step 2 to the dehydrated ethanol solution at -10 degrees Celsius according to the dry weight according to the solid-liquid ratio of 1g:12mL, and stirring for 20min to extract and dissolve the fragrance. The temperature of cold absolute ethanol is -20~-10 degrees Celsius;

[0052] Step 4. Extraction: Add 360ml of demineralized water and 240mL of absolute ethanol to the material liquid after extracting and dissolving fragrance in step 3. At this time, the mass concentration of ethanol in the extraction liquid is 90%,...

Abstract

The invention belongs to the field of processing of Chinese date powder and in particular relates to a processing process of instant red date powder. The processing process comprises the following steps: (1) pre-treating; (2) enhancing aroma; (3) dissolving the aroma; (4) extracting; (5) removing ethanol; (6) drying. The processing process specifically comprises the following steps: selecting good red dates and cleanly washing; wiping and slicing; carrying out dry heat treatment on the red date slices to enhance the aroma; adding into a cold absolute ethanol solution while the red date slices are hot and stirring to dissolve the aroma; supplementing softened water and absolute ethanol, and then reflowing and extracting for two times; combining filtrates; after removing ethanol from the filtrate, adding a drying auxiliary agent and performing spraying drying to obtain the instant red date powder. The processing process has a simple process; the prepared instant red date powder has a high powder collection rate, good solubility, rich aroma and high content of nutrients and active components; less auxiliary materials are added so that the pure aroma, taste and color and luster of the red dates are kept.

Description

technical field [0001] The invention belongs to the technical field of jujube deep processing, and in particular relates to a processing technology of instant jujube powder. Background technique [0002] The Chinese nation has a long tradition of diet therapy and health preservation. For thousands of years, our ancestors have accumulated a lot of experience in health care and health care in the practice of physical fitness, and formed a health care theory with Chinese characteristics. The discussion of the same origin of medicine and food in ancient times is actually the core point of view of food health care. Traditional Chinese medicine, as a traditional medicine and health culture, is still an important theoretical basis and effective material source for the development of functional foods in my country. It is also the basis for the development of functional foods in China. unique advantage [77] . [0003] With the rapid development of the economy and the continuous impr...
