Problems solved by technology

[0003] Fruit and vegetable lozenges are a new form of ready-to-eat food. At present, a variety of preparation methods of wolfberry lozenges have been disclosed in the prior art. However, the patent for preparing double-layer tablets by combining wolfberry with other foods is limited to the application number CN201410159905 and two patents of CN201410114102, these two patents have adopted red wolfberry and black fruit wolfberry compatibility, through the process preparation method of fresh fruit juice, fresh juice sterilization, dry milling, tabletting, although the taste of this kind of product is relatively Good, but the fresh juice and dried product of wolfberry are used in the preparation of the product, the nutritional content is far from that of fresh fruit, and a large amount of insoluble components in fresh fruit remain in the skin dregs

Embodiment 1

[0031] (1) Preparation of freeze-dried wolfberry granules: remove immature fruit, silt, and stone impurities in the fresh fruit of wolfberry, wash it with 0.5% sodium carbonate aqueous solution for 5 minutes, drain and let it stand for 3 hours, and then spray it with pure water. Rinse and rinse, freeze fresh goji berries to -20°C, then dry at 45°C under 0.08MPa vacuum until the moisture content is lower than 6%, and then freeze-dried goji berries are obtained. Crush the freeze-dried goji berries to 80 meshes, and sieve the goji berries Seeds, dry granulation, sieve to get 1mm particle size.

[0032] (2) Preparation of wolfberry sprouts granules: take fresh wolfberry sprouts and wash them by bubbling for 10 minutes, then spray and rinse them with pure water, centrifuge at 1000r / min for 60s to remove surface moisture, freeze the obtained wolfberry sprouts to -20°C, and Under 0.08MPa vacuum, dry at 40°C until the moisture content is lower than 6%, to obtain freeze-dried wolfberry...

Abstract

The invention relates to a freeze-drying Chinese wolfberry and Chinese wolfberry sprout double-layer tablet and a preparation method thereof. The freeze-drying Chinese wolfberry and Chinese wolfberry sprout double-layer tablet is characterized by consisting of a Chinese wolfberry layer and a Chinese wolfberry sprout layer in a weight ratio of 3:7 to 7:3, wherein the Chinese wolfberry layer is seed-removed freeze-drying Chinese wolfberry powder, and the Chinese wolfberry sprout layer is freeze-drying Chinese wolfberry sprout powder and binder. The freeze-drying Chinese wolfberry and Chinese wolfberry sprout double-layer tablet has the following beneficial effects: 1, the prepared double-layer tablet adopts the Chinese wolfberry and the Chinese wolfberry sprout as raw materials, thereby containing all nutrition ingredients besides the root, and being richer in taste; 2, by adopting an advanced vacuum freeze drying technology, the nutrition loss in the processing is avoided, and the original flavor and characters of the Chinese wolfberry and the Chinese wolfberry sprouts can be maintained; 3, the prepared Chinese wolfberry layer is total Chinese wolfberry powder, no auxiliary material is added, the Chinese wolfberry sprout layer is only provided with the binder, so that the safety in eating is guaranteed; 4, the method is simple in process, and a finished product is convenient to eat, store and transport.

Description

technical field [0001] The invention relates to a double-layer tablet of freeze-dried wolfberry and wolfberry sprouts and a preparation method thereof. Background technique [0002] Lycium barbarum is a traditional precious Chinese medicinal material and an important economic crop with a long history in China. As a nourishing product with the same source of food and medicine, it has various physiological activities and health care functions. Experimental analysis shows that wolfberry contains many nutritional and functional ingredients, such as wolfberry polysaccharides, carotenoids, betaine, vitamins, trace elements and so on. Medical research has shown that wolfberry has a very significant immune regulation effect on non-specific immunity and specific immunity. protrude. Lycium barbarum sprouts, that is, the young shoots and leaves of wolfberry. The content of trace elements in wolfberry buds is higher than that of ordinary vegetables. In addition, it also contains wolf...
