Embodiment 1

[0046] Bracken includes the young leaves of fern (pteridium aquilium (L.) Kuhn Var latiusculum (Desv.)) in the family Pteridaceae, and the young leaves refer to: the young leaves of Bracken in April-May every year During the rolling period, pick the young leaves with petioles that grow 15-20 cm above the ground.

[0047] The preparation method of steam-exploded bracken tea comprises the following process steps:

[0048] A. Harvesting

[0049] From April to May every year, during the tender leaves of bracken, young leaves with petioles that grow 15-20 cm above the ground are picked.

[0050] B. Sorting

[0051] Remove the yellow leaves and impurities mixed in when the bracken is harvested.

[0052] C. to clean

[0053] Wash the sorted bracken with clean water.

[0054] D. Finished

[0055] Boil the cleaned bracken in water for 1-5 minutes, the boiling temperature is 80-100°C, and spread out in time to cool down after finishing.

[0056] E. dry

[0057] Under the condition...

Embodiment 2

[0069] In the drying step, the fern that has been killed can also be dried at a temperature lower than 100°C.

[0070] During the steam explosion, the bracken can be directly put into the steam explosion chamber without being cut into sections, and the steam explosion can be carried out under the pressure condition of 3.0MPa for 5 seconds.

[0071] Collect steam explosion materials and dry them at 50°C to obtain steam explosion dried materials.

[0072] The processing conditions of other operations are with embodiment 1.

Abstract

The invention relates to a steam exploded fiddlehead tea preparation method, which solves the problems of low dissolving-out speed and dissolving-out amount of flavones, and the reinforced fishy smell with the reduced water temperature. The invention comprises: harvesting fiddleheads, sorting, cleaning, deactivating enzymes and sun drying; steam exploded treating which includes: putting the sun dried fiddlehead into steam exploding chamber with amount no less than 1 / 4 of the steam exploding chamber each time, steam exploding under the pressure of 1.0-1.3MPa for 5-90 seconds to obtain steam exploded fiddlehead; drying the steam exploded fiddlehead, sieving to obtain the oversize and the undersize; the oversize is made into socking type steam exploded fiddlehead tea; ultra-fine grinding the undersize to powder of 200-2000mu which is instant type steam exploded fiddlehead tea. The fiddlehead tea prepared by the invention achieves a faster flavones dissolving-out speed, a higher flavones dissolving-out amount twice of that of the non-steam exploded fiddlehead tea; intensifies the coking fragrance of the fiddlehead tea, improves the fiddlehead tea flavor greatly, removes the prior fishy smell, and makes it more suitable for different people.

Description

technical field [0001] The invention relates to a preparation method of bracken tea. Background technique [0002] Bracken is collected from the young leaves of fern (pteridium aquilium (L.) Kuhn Varlatiusculum (Desv.)) in the family Pteridaceae. Edible wild vegetables. Widely promulgated all over the country, and also in other temperate regions of the world, growing margins and barren slopes, 200-1200m above sea level; rhizomes provide fern powder and nourish food; the whole plant is used as medicine, rheumatism, diuretic and antipyretic, and prolapse. Insect repellant, with high food value and medicinal value. [0003] As a wild vegetable, bracken has entered thousands of households and is on the table of common people. Now many large shopping malls and supermarkets sell bracken food. my country also has bracken food exports. However, the development of bracken is still low-level and low-level. The main processing methods are salting, drying, making soft cans, etc., an...
