Problems solved by technology

[0004] To sum up, the existing lotus leaf tea products have the following technical problems: (1) The eating method is single, only soaking and drinking soaking water, and there are no other consumption methods, which will inevitably cause insufficient dissolution of active ingredients and cannot be effectively used. The lotus leaf dietary fiber is not available. It can be used, and it cannot be used for other purposes to expand the usage and application fields of lotus leaf tea
(2) The vast majority of lotus leaf teas sold on the market are directly dried with fresh lotus leaves (sun-dried or artificially dried by equipment), and the color, aroma, and shape are poor, and the edible quality is not good, which is also the cause One of the reasons for the low sales of products

preparation example Construction

[0019] A preparation method of lotus leaf tea superfine powder, comprising the steps of:

[0020] Step 1. Raw material picking: choose fresh lotus leaves with emerald green color, no defects, and no pollution. The lotus leaf maturity is 7-9 years old.

[0021] Step 2. Withering: The lotus leaves cut into appropriate sizes are placed on a well-ventilated withering bed for spreading and withering. After withering, the water content of the lotus leaves is 65-75%.

[0022] Step 3. Finishing: adopt steam finishing method and use tunnel steam finishing equipment. The thickness of the lotus leaves is 2-4cm, adjust the speed of the belt to control the greening time of the lotus leaves at 2-4min, and adjust the steam input to control the temperature in the tunnel between 85-95°C. It is better to keep the lotus leaves bright green after finishing. After finishing, let it cool down to room temperature immediately. Studies have proved that the color and flavor of the final product of l...

Embodiment 1

[0029] Embodiment 1, a kind of preparation method of lotus leaf tea superfine powder, comprises the steps:

[0030] Take 100kg of lotus leaves, step 1, raw material picking: choose fresh lotus leaves with emerald green color, no defects, and no pollution. The lotus leaf maturity is 7 years old.

[0031] Step 2. Withering: The lotus leaves cut into appropriate sizes are placed on a well-ventilated withering bed for spreading and withering. The thickness of the lotus leaves on the withering bed is 4 cm, and the withering time is 7 hours. The water content of lotus leaves after withering is 70%.

Abstract

The invention provides a preparation method for lotus leaf tea superfine powder. The preparation method comprises the following steps: 1, picking raw materials; 2, withering; 3, removing green; 4, rolling; 5, drying and removing aroma; 6, coarsely crushing and carrying out superfine crushing. The lotus leaf tea is obtained by carrying out superfine crushing; the lotus leaf tea has the effects that (1) the bioavailability of effective components of lotus leaves is improved and the loss rate of the effective components does not exceed 20%; the dissolution rate and the digestion rate of the effective components are respectively improved by 40% and more than 200%; (2) an ingestion manner of the lotus leaf tea is changed; after the lotus leaf tea superfine powder enters an oral cavity of a person, the coarse mouth feel can not be felt, thus the manner of drinking the lotus leaf tea is changed into the manner of directly ingesting the lotus leaf tea; (3) after the lotus leaf tea is produced by a traditional tea making technology, the superfine processing is carried out so that the lotus leaf tea superfine powder has the optimal color and luster, aroma and taste; (4) the utilization channel and field of lotus leaves are expanded and the lotus leaf tea superfine powder can be used as auxiliary materials of foods, medicines and daily cosmetics.
