Embodiment 1

[0031] A processing method of macadamia nut leaf black tea, comprising the steps of:

[0032] (1) Picking fresh leaves: Pick young leaves of macadamia nuts and collect them; pick and cut young sugarcane leaves and cut them into 5-10cm sections for later use;

[0033] (2) Sun-drying and hot-drying treatment: spread the macadamia nut leaves in a dustpan, and start at 17:00 in the evening, place them outdoors for sun-drying, with a thickness of 2-3cm, dry for 30 minutes, and control the water content at 70-85%. spare.

[0034] The cut sugarcane tender leaves are rinsed in clean water for 2 to 5 minutes; then put into hot water (60°C) added with baking soda (0.1 to 0.5% of the weight of the hot water) for blanching for 6 to 5 minutes. After 8 minutes, pick it up and put it in clean water to cool for 8-10 minutes, then dry it until the water content is between 50-60%, and set it aside.

[0035] (3) Heavy withering: thinly spread the macadamia nut leaves and sugarcane leaves in st...

Embodiment 2

[0043] A processing method of macadamia nut leaf black tea, comprising the steps of:

[0044] (1) Picking of fresh leaves: Pick young leaves of macadamia nuts and collect them; pick and cut young leaves of sugarcane and cut them into 10-20cm sections for later use;

[0045] (2) Sun-drying and hot-drying treatment: Spread the macadamia leaves in a dustpan, and start at 16:00 in the evening, place them outdoors for sun-drying, with a thickness of 1-2cm, dry for 20 minutes, and control the water content at 70-85%. spare.

[0046] The cut sugarcane tender leaves are rinsed in clean water for 2 to 5 minutes to remove impurities such as dust and floating hair; then put into hot water (70 ℃) for 5 minutes, scoop it up and put it in clean water to cool for 5-6 minutes, then dry it until the water content is between 50-60%, and set it aside.

[0047] (3) Heavy withering: Spread the macadamia nut leaves and sugarcane leaves from step (2) on a dustpan for indoor withering. The thicknes...

Embodiment 3

[0055] A processing method of macadamia nut leaf black tea, comprising the steps of:

[0056] (1) Picking fresh leaves: Pick young leaves of macadamia nuts and collect them; pick and cut young sugarcane leaves and cut them into 10-15cm sections for later use;

[0057] (2) Sun-drying and hot-drying treatment: spread the macadamia leaves in a dustpan, and place them outdoors at 17:30 in the evening, with a thickness of 2-3cm, dry for 25 minutes, and control the water content at 70-85%, and set aside .

[0058] The cut sugarcane tender leaves are rinsed in clean water for 2 to 5 minutes to remove impurities such as dust and floating hair; then put into hot water (65 ℃) for 5-8 minutes, scoop it up and put it in clean water to cool for 6-8 minutes, then dry it until the water content is between 50-60%, and set it aside.

[0059] (3) Heavy withering: thinly spread the macadamia nut leaves and sugarcane leaves in step (2) on a dustpan for indoor withering. The thickness of the thi...

Abstract

The invention discloses a processing method for black tea from macadamia ternifolia leaves. The processing method comprises the following technological steps: fresh leaf picking, re-withering, kneading, unblocking, fermenting, drying, flavor improving and the like. According to the processing method, the natural macadamia ternifolia leaves and tender sugarcane leaves are used as raw materials, and are blended in proportion, the targeted processing techniques of sun-withering, kneading, fermenting and the like are adopted to fully blend effective constituents of the macadamia ternifolia leaves and the tender sugarcane leaves, the effective constituents are easy to leach, the taste is mellow, and the effects such as reducing blood pressure and reducing serum cholesterol are achieved.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a method for preparing black tea. Background technique [0002] Macadamia nuts (Latin name: Macadamia ternifolia F. Muell. ) Alias: Queensland Chestnut, Australian Walnut, Macadamia Nut, Queensland Nut. Macadamia is native to the subtropical rainforests of Queensland and New South Wales, Australia, and is an evergreen nut tree. The critical temperature for tree growth is 10°C to 15°C. Branches, leaves and roots grow in abundance at 20°C, 25°C and 15°C, respectively. The average temperature is 25°C, the maximum temperature does not exceed 38°C, and almost no frost in winter is an ideal temperature condition. [0003] Macadamia nuts have a fat content of 65%~83%, rich in a variety of unsaturated fatty acids and 8 essential amino acids, trace elements and vitamins, such as phosphorus, iron, vitamins B1 and B2. Macadamia nuts are crispy, smooth, tender and delicious, with...
