Embodiment 1
[0048] A preparation process for edible bean dregs paper, comprising the following steps:
[0049] Step 1: First, ultrafinely pulverize the bean dregs (ultrafine pulverizer) to 60 meshes. According to the mass ratio of bean dregs:water of 1:100, add water and mix evenly, and boil for 2 minutes to fully swell the bean dregs fibers to form the first Okara fiber solution;
[0050] Step 2, concentrating the fiber content of the first bean dregs to 5% by mass, heating to 30°C, and adding 0.1% lipase to hydrolyze for 2h at pH 6.5;
[0051] After washing, form the second bean dregs fiber solution with a mass percentage of 5%, heat it to 35°C, and add 0.5% protein to enzymatically hydrolyze it for 2 hours at pH 7.5, rinse it clean, and prepare the third bean dregs fiber solution with a mass percentage of 8%. Okara fiber solution;
[0052] Step 3, heating the 8% okara fiber solution in step 2 to 30°C, adding 0.6% sodium carboxymethyl cellulose, 0.3% modified starch and 0.3% by mass ...
Embodiment 2
[0058] A preparation process for edible bean dregs paper, comprising the following steps:
[0059] Step 1: First, ultrafinely pulverize the bean dregs (ultrafine pulverizer) to 100 meshes. According to the mass ratio of bean dregs:water of 2:100, add water and mix evenly, and boil for 3 minutes to fully swell the bean dregs fibers to form the first Okara fiber solution;
[0060] Step 2, concentrating the fiber content of the first bean dregs to 10% by mass, heating to 40°C, and adding 0.6% lipase to hydrolyze for 2.5h at a pH of 7.5;
[0061] After washing, a second bean dregs fiber solution with a mass percentage of 10% was formed, heated to 55°C, and at pH 8.0, 1.2% by mass of protein was added to enzymatically hydrolyze it for 2 hours, rinsed, and configured into a third bean dregs solution with a mass percentage of 12%. Okara fiber solution;
[0062] Step 3, heating the third okara fiber solution with 12% mass percentage in step 2 to 30°C, adding 1.1% sodium carboxymethy...
Embodiment 3
[0068] A preparation process for edible bean dregs paper, comprising the following steps:
[0069] Step 1: First, ultrafinely pulverize the bean dregs (ultrafine pulverizer) to 120 mesh. According to the mass ratio of bean dregs:water of 4:100, add water and mix evenly, and boil for 3 minutes to fully swell the bean dregs fibers to form the first bean dregs fiber solution;
[0070] Step 2, concentrating the fiber content of the first bean dregs to 20% by mass, heating to 45°C, and adding lipase hydrolysis of 1.0% by mass for 2h at a pH of 8.0;
[0071] After washing, the second bean dregs fiber solution with a mass percentage of 20% was formed, heated to 55°C, and at a pH of 8.5, 1.8% by mass of protein was added for enzymatic hydrolysis for 3.5 hours, rinsed, and prepared into a third solution with a mass percentage of 20%. Okara fiber solution;
[0072] Step 3, heating the third okara fiber solution of 20% by mass in step 2 to 25°C, adding 3.0% sodium carboxymethyl cellulo...
