Embodiment 1
[0048] 1. Prepare bamboo shoot powder
[0049] 1) Take the bamboo shoots and wash them, remove the damaged, uneven, and uneven parts, chop them with a shredder, and place them in a homogenizer for 30 minutes to obtain a fiber homogenate of the bamboo shoots. The rotating speed of the pulp machine is 4500 rpm, and the moisture content of the bamboo shoots is 85.7%;
[0050] 2) Put the bamboo shoot fiber homogenate in a vacuum drying oven (Beijing Grawell Technology Co., Ltd., model DZF6090) to dry, control the drying temperature to 70°C, and dry it until the moisture content is 5% before pulverizing to obtain 40 mesh bamboo shoot powder.
[0051] 2. Enzymatic hydrolysis and wall breaking treatment
[0052] 1) Adding water to the bamboo shoot powder and stirring evenly to obtain a mixed liquid of bamboo shoot powder, the ratio by weight of the bamboo shoot powder to water is 4:1;
[0053] 2) adding a monosodium citrate solution with a concentration of 10% by mass to adjust th...

[0073] 1. Prepare bamboo shoot powder
[0074] 1) Take the bamboo shoots and wash them, remove the damaged, uneven, and uneven parts, chop them with a shredder, and place them in a homogenizer for 60 minutes to obtain a fiber homogenate of the bamboo shoots. The rotating speed of the pulp machine is 3000 rpm, and the moisture content of the bamboo shoots is 83.5%;
[0075] 2) The bamboo shoot fiber homogenate is placed in a vacuum drying oven for drying, the drying temperature is controlled at 80° C., and it is dried until the moisture content is 6%, and then pulverized to obtain 60-mesh bamboo shoot powder.
[0076] 2. Enzymatic hydrolysis and wall breaking treatment
[0077] 1) Adding water to the bamboo shoot powder and stirring evenly to obtain a mixed liquid of bamboo shoot powder, the ratio by weight of the bamboo shoot powder to water is 4:1;
[0078] 2) adding a lactic acid solution with a mass percent concentration of 15% to adjust the pH of the bamboo shoot powder ...
Embodiment 3
[0093] 1. Prepare bamboo shoot powder
[0094] 1) Take the bamboo shoots and wash them, remove the damaged, uneven, and uneven parts, chop them with a shredder, and place them in a homogenizer for 20 minutes to obtain a fiber homogenate of the bamboo shoots. The rotating speed of the pulp machine is 5000 rpm, and the moisture content of the bamboo shoots is 85.0%;
[0095] 2) The bamboo shoot fiber homogenate is placed in a vacuum drying oven for drying, the drying temperature is controlled at 80° C., dried to a moisture content of 5%, and then pulverized to obtain 50 mesh of bamboo shoot powder.
[0096] 2. Enzymatic hydrolysis and wall breaking treatment
[0097] 1) Adding water to the bamboo shoot powder and stirring evenly to obtain a mixed liquid of bamboo shoot powder, the ratio by weight of the bamboo shoot powder to water is 4:1;
[0098] 2) adding a malic acid solution with a concentration of 20% by mass to adjust the pH of the bamboo shoot powder mixture to 6.5;
