Problems solved by technology

[0003] Bitter bamboo shoots are used as food. In order to make them taste better, the bitter substances in the bitter bamboo shoots are often removed by rinsing process during processing. However, although the traditional rinsing process can remove part of the bitter components in the bitter bamboo shoots, it will also cause Loss of nutrients such as dietary fiber

Embodiment 1

[0023] A preparation method of bitter bamboo shoot powder, the method comprising:

[0024] Take fresh bitter bamboo shoots, wash and peel them, cut into 3*3*3mm pieces of bitter bamboo shoots, and get pre-treated bitter bamboo shoots;

[0025] adding water and the first composition to the pretreated bitter bamboo shoots for rinsing and boiling;

[0026] Beat the boiled bitter bamboo shoots, add a compound enzyme for enzymolysis, the compound enzyme is a mixture of papain and fiber film at a weight ratio of 1:2, and the amount of compound enzyme added accounts for 0.1% of the weight of the bitter bamboo shoot pulp, and the enzymatic hydrolysis The time is 50-70min, the temperature is 55-65°C, the pH is 5-6, and the first sample is obtained;

[0027] vacuum freeze-drying the first sample to obtain a second sample;

[0028] Jet milling the second sample;

[0029] Wherein, the first composition is a mixture of citric acid and sodium D-isoascorbate at a weight ratio of 3:1, and ...

Embodiment 2

[0031] A preparation method of bitter bamboo shoot powder, the method comprising:

[0032] Fresh bitter bamboo shoots are selected, cleaned, peeled and then cut into 3*3*3mm pieces of bitter bamboo shoots to obtain pretreated bitter bamboo shoots;

[0033] Weigh 3 kg of drinking water and 1 kg of pretreated bitter bamboo shoots for mixing, then add 4 g of citric acid and 1 g of sodium D-isoascorbate, and boil for 2 hours;

[0034] After rinsing, the bitter bamboo shoots are drained of excess water, beaten, and then enzymatically hydrolyzed with papain and cellulase (papain: cellulase = 1:2). The amount of enzyme solution added is 0.1%, and the enzymolysis time is 45 min, the temperature is 55°C, and the pH is 5.5 to obtain the first sample;

[0035] The first sample is subjected to vacuum freeze-drying treatment, that is, the vacuum freeze dryer is run to pre-cool, and then the enzymatically hydrolyzed bitter bamboo shoot slurry is placed in a clean tray, and cold hydrazine i...

Embodiment 3

[0039] Fresh bitter bamboo shoots are selected, cleaned, peeled and then cut into 3*3*3mm pieces of bitter bamboo shoots to obtain pretreated bitter bamboo shoots;

[0040] Weigh 3 kg of drinking water and 1 kg of pretreated bitter bamboo shoots, mix them, then add 6 g of citric acid, 2 g of sodium D-isoascorbate, and boil for 2 hours;

[0041] After rinsing, the bitter bamboo shoots are drained of excess water, beaten, and then enzymatically hydrolyzed with papain and cellulase (papain: cellulase = 1:2). The amount of enzyme solution added is 0.1%, and the enzymatic hydrolysis time is 60 min, the temperature is 60 ℃, and the pH is 5.5, the first sample is obtained;

[0042] The first sample is subjected to vacuum freeze-drying treatment, that is, the vacuum freeze dryer is run to pre-cool, and then the bitter bamboo shoot slurry after enzymolysis is placed in a clean tray, and cold hydrazine is put into the sample to pre-freeze the sample. 1 h below the eutectic point, remov...

Abstract

The invention belongs to the field of bamboo shoot processing, and discloses a bitter bamboo shoot powder preparation method. The method comprises the steps: adding water and a first composition to pretreated bitter bamboo shoots, rinsing, and boiling; pulping the boiled bitter bamboo shoots, and adding a compound enzyme for enzymolysis to obtain a first sample; performing vacuum freeze drying onthe first sample to obtain a second sample; and carrying out jet milling on the second sample. The bitter bamboo shoot powder prepared by the method can effectively reduce the loss of nutrient substances in bitter bamboo shoots while removing bitter taste, and contains higher total dietary fibers.

Description

technical field [0001] The invention relates to the field of bamboo shoot product processing, in particular to a preparation method of bitter bamboo shoot powder. Background technique [0002] Bitter bamboo shoots are the tender seedlings of the grass plant bitter bamboo. It has the effects of clearing away heat and annoyance, diuresis and dehumidification. It is mainly used to treat diseases such as fever, polydipsia, dysuria, damp-heat jaundice, beriberi, etc. It has a long history of medicinal use. The Ming Dynasty "Compendium of Materia Medica" has Records: "Bitter bamboo shoots taste bitter, sweet and cold, and are mainly used to treat insomnia, remove face and yellow tongue, quench thirst and improve eyesight, relieve alcohol poisoning, remove heat, benefit energy, diuresis, lower qi and reduce phlegm, regulate wind-heat and beriberi, and cure After sweating, I have a cold and lose my voice." Bitter bamboo shoots are not only rich in amino acids and minerals, it is a ...
