Embodiment 1

[0032] The method for producing dietary fiber with tea millet as raw material comprises the following steps:

[0033] (1) Raw material pretreatment: After removing impurities from the tea, add distilled water 10 times its weight, soak for 2 hours, filter to obtain filtrate and filter residue, and set aside;

[0034] (2) Cooking: The filter residue obtained in step (1) is subjected to high-pressure ultrasonic treatment, cooled to room temperature, and set aside;

[0035] (3) Enzymatic removal of impurities: take the cooked filter residue, add the filtrate in step (1), adjust the pH to 6.5, add neutral protease and amylase for enzymatic removal of impurities, keep the temperature at 30°C, and enzymatically hydrolyze for 3 hours; then heat up Heat at 95°C and keep warm for 3 minutes to inactivate the enzyme; after cooling, filter and dry to obtain the filter-dried product for later use;

[0036] (4) Hydrolysis: Take the dried filter obtained in step (3), add distilled water 5 ti...

Embodiment 2

[0047]The method for producing dietary fiber with tea millet as raw material comprises the following steps:

[0048] (1) Raw material pretreatment: After removing impurities from the tea, add distilled water 20 times its weight, soak for 4 hours, filter to obtain filtrate and filter residue, and set aside;

[0049] (2) Cooking: The filter residue obtained in step (1) is subjected to high-pressure ultrasonic treatment, cooled to room temperature, and set aside;

[0050] (3) Enzymatic removal of impurities: take the cooked filter residue, add the filtrate in step (1), adjust the pH to 7.0, add neutral protease and amylase for enzymatic removal of impurities, keep the temperature at 40°C, and enzymatically hydrolyze for 2 hours; then heat up Heat at 100°C and keep warm for 2 minutes to inactivate the enzyme; after cooling, filter and dry to obtain the filter-dried product for later use;

[0051] (4) Hydrolysis: take the dried filter obtained in step (3), add 8 times its weight i...

Embodiment 3

[0062] The method for producing dietary fiber with tea millet as raw material comprises the following steps:

[0063] (1) Raw material pretreatment: After removing impurities from the tea, add distilled water 30 times its weight, soak for 5 hours, filter to obtain filtrate and filter residue, and set aside;

[0064] (2) Cooking: The filter residue obtained in step (1) is subjected to high-pressure ultrasonic treatment, cooled to room temperature, and set aside;

[0065] (3) Enzymatic removal of impurities: take the cooked filter residue, add the filtrate in step (1), adjust the pH to 7.5, add neutral protease and amylase for enzymatic removal of impurities, keep the temperature at 50°C, and enzymatically hydrolyze for 1 hour; then raise the temperature Heat at 100°C and keep warm for 2 minutes to inactivate the enzyme; after cooling, filter and dry to obtain the filter-dried product for later use;

[0066] (4) Hydrolysis: take the dried filter obtained in step (3), add 8 time...

Abstract

The invention discloses a method for producing dietary fiber by taking downy buds as raw materials. The method includes the following steps: (1) pretreating the raw material, (2) steaming, (3) removing impurities by enzymes, (4) hydrolyzing, (5) purifying, (6) soaking with a sodium hydroxide solution, and (7) vacuum drying to prepare the dietary fiber of downy buds. The production method has the advantages of low raw material cost, simple equipment and operation, can realize large-scale production, maximally improve the utilization value of the downy buds, change waste into treasure, can improve the added value of the downy buds, solve the problem of waste of the downy buds, and has important significance for comprehensive utilization and deep processing of the downy buds.

Description

technical field [0001] The invention relates to the technical field of tea hair processing, in particular to a method for producing dietary fiber by using tea hair as a raw material. Background technique [0002] Camellia genus Camellia ( Theaceae ) Camellia ( Camellia L. ), a perennial evergreen plant, originated in Southwest my country and has a cultivation history of more than 3,000 years. With the evolution of tea tree natural selection, the morphological characteristics of tea tree also change accordingly, and tea hair is the product of long-term evolution. Tea hair is the fine fluff on the tip of tea buds, also called tea hair, which is rich in nutrients such as theanine and tea polyphenols. This indicator is used as an important indicator of tea tenderness in many cases. Generally speaking, the tenderer the fresh leaves, the more tea leaves. There are many teas, especially green tea and black tea, such as Maojian. "Chinese Tea Dictionary" describes tea hair as: ...
