Red jujube medlar health-care powder and production method thereof

Abstract

The invention discloses red jujube medlar health-care powder and a production method thereof, and belongs to the field of food processing. The red jujube medlar health-care powder is prepared from the following raw materials by weight percent: 40% to 70% of red jujube powder, 10% to 30% of medlar powder, 10% to 20% of cooked soybean meal, 5% to 12% of maltodextrin, 0.5% to 1.0% of a nutrition enhancer. 1.0% to 2.0% of an anti-blocking agent and 0.5% to 1.0% of glycerin monostearate, wherein all the raw materials are put into a three-dimensional mixer according to a certain feeding sequence and are mixed so as to obtain the red jujube medlar health-care powder. The red jujube medlar health-care powder is pure and natural as well as fine and smooth in taste, good in health-care effect and less in nutrient substance loss and waste because maintaining the original pure fragrance of red jujubes and medlar. The defects that the red jujubes and the medlar are difficult to pulverize, easy to stick and not enough in fineness are solved by utilizing the instantaneous liquid nitrogen freezing combined with a low-temperature airflow superfine smashing technology. The operation working procedure for producing the red jujube medlar health-care powder is convenient, so that the processing time is saved; the energy conservation and the consumption reduction are realized. As a result, the red jujube medlar health-care powder is suitable for mass production for a long time.

Description

Technical field [0001] The invention belongs to the field of food processing, and particularly relates to a red jujube and wolfberry health-care powder and a production method thereof. Background technique [0002] Red dates have been listed as one of the "five fruits" (peach, plum, plum, apricot, and jujube) since ancient times, with a long history. Jujube contains a high content of vitamins. A clinical study abroad shows that patients who continue to eat jujube can recover more than three times faster than taking vitamin medicine alone. Therefore, jujube has the reputation of "natural vitamin pill". At the same time, red dates also have the following effects: 1. Improve human immunity, inhibit cancer cells, promote the production of white blood cells, reduce serum cholesterol, increase serum protein, and protect the liver; 2. Prevent the formation of gallstones: Vitamin C in fresh dates will improve The excess cholesterol in the body is converted into bile acid, which reduces...

AI Technical Summary

Problems solved by technology

[0005] At present, there are many single or compound jujube and wolfberry nutrition and health care powders prepared with red dates and wolfberry as the main raw materials, or with the addition of other auxiliary materials. The two traditional powder making methods have different and obvious defects: wet powder making: beating raw materials, homogenizing, adding a large amount of desiccant to prepare, homogenizing, spray drying, sieving, crushing The existing defects are as follows: 1. There are many processes and more impurities and harmful substances are brought in; 2. There are many equipments in the milling process, which consumes a lot of energy; 3. Add more drying aids, The produced jujube or wolfberry powder is not pure powder, and loses the original fragrance and pure fragrance of red dates and wolfberry; 4. Due to the high sugar content of red dates and wolfberry, it is difficult to control the temperature during the wet milling process, resulting in serious slurry Wall sticking phenomenon; 5. After milling, since the fineness does not meet the requirements, it is necessary to carry out secondary crushing after sieving. During the crushing process, large particles of powder are prone to stickiness; dry powder milling: red dates and wolfberry are dried at high temperature Simple crushing after drying, although the energy consumption is less and the impurities and harmful substances brought in are less, but there are also certain defects, such as: 1. The sugar content of red dates and wolfberry is very high. A large amount of heat generated by friction makes the material sticky and difficult to make powder; 2. During the dry powder process, the heat-sensitive substances in red dates and wolfberry are destroyed due to high-temperature drying of materials, and even harmful substances are produced; 3. During the dry powder making process, due to the stickiness of the material, the fineness of the powder produced is difficult to meet the use requirements.
