Embodiment 1
[0037] 1) Peel the potatoes, cut them into 5mm×5mm×5mm pieces, soak in 8 times the volume of 0.05M HCl solution, and shake at a constant speed of 100rpm for 6h;
[0038] 2) Rinse the acid-soaked potato pieces with tap water or pure water until neutral, soak in 8 times the volume of 0.025M NaOH solution, and shake at a constant speed of 100rpm for 12h;
[0039] 3) mash the potatoes soaked in acid and alkali, then add tap water or purified water to the mashed potatoes, and pass through a 150 μm sieve for 4 times to obtain coarse potato particles and coarse pulp;
[0040] 4) Knead the coarse particles in step 3) again to make mud, add tap water or pure water to pass through a 150 μm sieve for 4 times, collect the obtained coarse particles and coarse slurry respectively, mash the obtained coarse particles again to make mud, add tap water or Purified water was passed through a 150 μm sieve 4 times, repeated 3 times, and the obtained coarse slurry was collected.
[0041] 5) Pass th...
Embodiment 2
[0046] 1) Take mature and plump kidney beans, peel them, soak them in 12 times the volume of 0.1M HCl solution, and shake them at a constant speed of 150 rpm for 24 hours;
[0047] 2) Rinse the acid-soaked kidney beans with tap water or pure water until neutral, soak in 12 times the volume of 0.06M NaOH solution, and shake at a constant speed of 200 rpm for 24 hours;
[0048] 3) mash the kidney beans soaked in acid and alkali to make mud, then add tap water or purified water to the kidney bean puree, and pass through a 180 μm sieve for 5 times to obtain kidney bean coarse particles and coarse pulp;
[0049] 4) Knead the coarse particles in step 3) again to make mud, add tap water or purified water to pass through a 180 μm sieve for 5 times, collect the obtained coarse particles and coarse slurry respectively, mash the obtained coarse particles again to make mud, add tap water or Purified water passed through a 180 μm sieve 5 times, repeated 4 times, and the obtained coarse slu...
Embodiment 3
[0055] 1) Take mature and plump wrinkled peas, peel them, soak them in 10 times the volume of 0.08M HCl solution, and shake them at a constant speed of 150 rpm for 12 hours;
[0056] 2) Rinse the acid-soaked peas with tap water or pure water until neutral, soak in 10 times the volume of 0.04M NaOH solution, and shake at a constant speed of 150rpm for 24h;
[0057] 3) mash the peas soaked in acid and alkali to make a puree, then add tap water or purified water to the pea puree, and pass through a 125 μm sieve for three times to obtain pea coarse particles and coarse pulp;
[0058] 4) Knead the coarse particles in step 3) again to make mud, add tap water or purified water to pass through a 125 μm sieve for 3 times, collect the obtained coarse particles and coarse slurry respectively, mash the obtained coarse particles again to make mud, add tap water or Purified water was passed through a 150 μm sieve 4 times, repeated 3 times, and the obtained coarse slurry was collected.
