Embodiment 1

[0028] Put 50 kilograms of fresh leaves of Dendrobium candidum on the stainless steel wire mesh three-dimensional spreading green frame, and spread it for 55 hours until the moisture content of the fresh leaves is 60%; the green leaves are fixed by a hot air cleaning machine, and the fixing temperature is 280 ° C. The moisture content of the green leaves is 50% after green killing; after the green green leaves are cooled, use a 40-type kneading machine to knead for 30 minutes; dry the processed kneaded leaves (hot air drying, drying, frying or rolling), After the drying is completed, the moisture content of the leaves of Dendrobium candidum is 6.5%; after the leaves of Dendrobium candidum are cooled, the leaves of Dendrobium candidum are crushed to obtain 8.5 kg of Dendrobium candidum leaves of 16-60 mesh; after extraction (50°C, 100min, leaf water ratio 1:20), 4.25 g (0.5 g / L) of cellulase and 25.5 g (3 g / L) of pectinase were added during the extraction process to obtain 145 k...

Embodiment 2

[0036] Spread 60 kg of fresh leaves of Dendrobium candidum on a stainless steel wire mesh three-dimensional spreading green frame, and spread it for 48 hours until the moisture content of the fresh leaves is 63%; the green leaves are fixed with a hot air cleaning machine, and the temperature of the greening treatment is 250°C. After finishing, the water content of the green leaves is 55%; after the green leaves are cooled, the 40-type kneading machine is used to knead and knead for 40 min; the processed kneaded leaves are rolled and dried, and the moisture content of the leaves of Dendrobium candidum is 7.5% after drying; After the leaves of Dendrobium officinale are cooled, crush the leaves of Dendrobium officinale to obtain 10.2 kg of Dendrobium officinale leaves of 16-60 mesh; after extraction (60°C, 90 min, leaf water ratio 1:50), add fiber during the extraction Sulfase 51 grams (5 g / L) and pectinase 1.2 grams (0.1 g / L) obtained 475 kg of dendrobium candidum leaf extract ju...

Embodiment 3

[0044] Put 50 kilograms of fresh leaves of Dendrobium candidum on a stainless steel wire mesh three-dimensional stand for 72 hours until the water content of the fresh leaves is 50%; the green leaves are fixed with a hot air cleaning machine at a temperature of 300°C. After finishing, the water content of the green leaves is 45%; after the green leaves are cooled, they are kneaded by a 40-type kneading machine for 20 min; After the leaves of Dendrobium officinale are cooled, crush the leaves of Dendrobium officinale to obtain 8.2 kg of Dendrobium officinale leaves of 16-60 mesh; after extraction (55°C, 120 min, leaf water ratio 1:30), add fiber Sulfase 16.4 grams (2 g / L) and pectinase 8.2 grams (1 g / L), obtained 215 kg of dendrobium candidum leaf extract juice.

[0045] Take 5 kg of mixed green tea (3 kg of green tea + 1 kg of oolong tea + 1 kg of white tea), extract at 55°C for 40 minutes according to the tea-water ratio of 1:50, and obtain 228 kg of green tea juice, after co...

Abstract

The invention discloses a processing method of a Dendrobium officinalis leaf tea beverage and belongs to the technical field of Dendrobium officinalis leaf tea beverage processing methods. The processing method includes following process steps: spreading Dendrobium officinalis leaves; dewatering spread leaves by using hot air; twisting dewatered leaves; drying twisted leaves; crushing and separately sieving Dendrobium officinalis leaves; extracting dried leaves of Dendrobium officinalis; extracting green tea; performing tannase treatment on tea juice; compounding and blending Dendrobium officinalis leaf extract and the tea juice; after-treating the composite tea juice. By using the processing method, the Dendrobium officinalis leaf tea beverage which is good in flavor and high in quality and has various healthcare effects can be obtained.

Description

technical field [0001] The invention belongs to the technical field of the processing method of the dendrobium candidum leaf tea beverage, and in particular relates to a processing method of the dendrobium candidium leaf tea beverage. Background technique [0002] Dendrobium officinale leaves are the dried leaves of Dendrobium officinale. Studies have shown that the active ingredients of Dendrobium officinale are mainly polysaccharides, which have the effects of enhancing immunity, anti-tumor, lowering blood fat, lowering blood sugar and anti-oxidation. Although the medicinal part of Dendrobium candidum is the plant stem, and the leaves are non-medicinal parts, there are literatures showing that the characteristic peaks of the HPLC fingerprints of Dendrobium candidum stems and leaves are basically the same, and the stems and leaves of Dendrobium candidum have the same Polysaccharide components, and the polysaccharide content of leaves is about one-third of that of stems. ...
