Embodiment 1

[0023] Embodiment 1: a kind of processing method of reshaping little purple sweet potato, comprises the steps:

[0024] a. Clean the raw purple sweet potato, then peel and remove impurities, and then cut into purple sweet potato pieces; Can be cut into strips of 3cm×5cm;

[0025] b. Carry out 4-6 hour hardening color protection treatment to purple sweet potato block with hardening color protection liquid, described hardening color protection liquid is mixed with the ratio of 1:0.005-0.02:0-0.02 by water, calcium chloride and sodium sulfite. In the present embodiment, described hardening color-protecting liquid is to be mixed with water, calcium chloride and sodium sulfite with the ratio of 1: 0.02: 0.005; Use sodium sulfite to make the color of purple sweet potato block brighter and brighter;

[0026] c. Rinse the treated purple sweet potato pieces with clean water to remove the hardened color protection solution on the surface, change the clean water once an hour, and rinse ...

Embodiment 2

[0038] Embodiment 2: according to the processing method of reshaping small purple sweet potatoes described in embodiment 1, the hardening color protection solution described in step b is formed by mixing water and calcium chloride in a ratio of 1:0.02;

[0039] Let's take the processing of 100KG raw purple potato as an example:

[0040]Select 100KG purple potatoes that are free from insects, pollution, and pesticides, wash off the soil on the surface of the purple potatoes with water, peel and remove impurities from the purple potatoes, and cut the purple potatoes into 3.5cm×3.5cm blocks; Put the purple sweet potato pieces into 75kg hardening color protection solution, the hardening color protection solution is mixed with water and calcium chloride at a ratio of 1:0.02, and the hardening color protection solution lasts for 4-6 hours. After hardening and color protection, the purple potato pieces are rinsed to remove the hardening color protection solution, and the water is cha...
