Embodiment 1
[0072] The implementation steps of this embodiment are as follows:
[0073] A. Raw material pretreatment
[0074] Taking no slicing as a control, fresh yams are taken for cleaning to remove surface mud and sand, and then the cleaned yams are cut into 1.5cm yam slices to obtain yam slices;
[0075] B. Color protection
[0076] The sliced yam in step A is placed in the color protection solution, the mass ratio of the color protection solution to the yam tablets is 3:1, and the color protection solution contains citric acid with a mass concentration of 0.3%, 0.2% D-iso Sodium ascorbate and 0.3% NaCl are soaked at room temperature for 35 minutes, and then the color-protecting solution on the surface is washed off to obtain fresh yam after color protection;
[0077] C. Refining
[0078] Add 2% D-sodium erythorbate based on the weight of fresh yam to the fresh yam obtained in step C after color protection, and then grind it into a slurry using a refining equipment until the slu...
Embodiment 2
[0087] The implementation steps of this embodiment are as follows:
[0088] A. Raw material pretreatment
[0089] Get fresh yam to clean, remove the surface mud and sand, then cut the cleaned yam into 2.0cm yam slices to obtain yam slices;
[0090] B. Color protection
[0091] Taking no place in the color-protecting solution as a control, place the sliced yam in step A in the color-protecting solution, the mass ratio of the color-protecting solution to the yam tablets is 2.5:1, and the color-protecting solution contains 0.3% of Soak citric acid, 0.2% sodium D-isoascorbate and 0.3% NaCl at room temperature for 35 minutes, then rinse off the color-protecting solution on the surface to obtain fresh yam after color protection;
[0092] C. Refining
[0093] Add 2% D-sodium erythorbate based on the weight of fresh yam to the fresh yam obtained in step C after color protection, and then grind it into a slurry using a refining equipment until the slurry can pass through a 65-mesh...
Embodiment 3
[0102] The implementation steps of this embodiment are as follows:
[0103] A. Raw material pretreatment
[0104] Get fresh yam to clean, remove the surface mud and sand, then cut the cleaned yam into 2.0cm yam slices to obtain yam slices;
[0105] B. Color protection
[0106] The sliced yam in step A is placed in the color protection solution, the mass ratio of the color protection solution to the yam tablets is 3:1, and the color protection solution contains citric acid with a mass concentration of 0.3%, 0.2% D-iso Sodium ascorbate and 0.3% NaCl are soaked at room temperature for 35 minutes, and then the color-protecting solution on the surface is washed off to obtain fresh yam after color protection;
[0107] C. Refining
[0108] Taking no addition of D-sodium erythorbate as a control, add 2% D-sodium erythorbate in terms of fresh yam weight to the fresh yam obtained in step C after color protection, and then use a refining equipment to grind it into a slurry until Th...
