Example Embodiment
[0027] Example 1: This embodiment adopts a mechanical extrusion production method.
[0028] Raw material formula (weight percentage): Eucommia leaf extract 1.5%, sweet potato starch 97.3, salt 1%, food additive 0.2%, food additive is zinc sulfate (0.004%) and a mixture of sodium polyacrylate and sodium alginate (0.196%) . The weight ratio of sodium polyacrylate and sodium alginate is 1:1 to 1.5.
[0029] The specific production method is:
[0030] (1) Kneading: Weigh the sweet potato starch, eucommia leaf extract, salt, zinc sulfate, sodium polyacrylate and acetate starch in proportion, add warm water and stir. The temperature of the warm water during mixing is 40℃, and the water content of the suspension slurry (liquid) is controlled within the range of 48-50%;
[0031] (2) Extrusion curing: The mixed starch suspension slurry is directly extruded by a screw extruder to complete curing. The starch suspension slurry should be filtered before entering the extruder. The diameter of th...
Example Embodiment
[0045] Example 2: This embodiment is a manual production method:
[0046] Raw material formula (weight percentage): Eucommia ulmoides ulmoides leaf extract 1.5%, sweet potato starch 97.2%, salt 1%, food additives 0.3%, food additives are zinc sulfate (0.004%) and a mixture of sodium polyacrylate and sodium alginate (0.296%). The weight ratio of sodium polyacrylate and sodium alginate is 1:1 to 1.5.
[0047] The specific production method is:
[0048] (1) Beating Gorgon: Put 0.57kg of sweet potato starch into the jar, add 1kg of 98℃ hot water to preheat, stir it evenly, it feels smooth and soft, it is uniform and transparent, and the paste is made into a paste;
[0049] (2) Heqian: Add about 9.3kg of sweet potato starch, 150g eucommia leaf extract, 100g salt, 0.4g zinc sulfate, 14.6g sodium polyacrylate and 15g sodium alginate to the gorgon paste, then add 7.5kg at 50°C In the 500r / min mixer, stir well for 15 minutes to obtain a uniform and fine dough, which is not sticky. Use a th...
