Embodiment 1

[0019] A kind of processing method of health preserved potato, concrete operation steps are:

[0020] (1) Selection of raw materials: choose potatoes with large tubers, thin skins, and less protein and fiber;

[0021] (2) Cleaning: Wash the sand and dust on the skin of the selected potatoes with clean water;

[0022] (3) Peeling: Put the potato tubers in a 100°C, 10% sodium hydroxide solution until the skin comes off when touched, then take it out and rinse with water immediately;

[0023] (4) Slicing: Cut the potatoes into thin slices with a thickness of 0.5cm with a slicer, and remove irregularly shaped potato chips and variegated potato chips;

[0024] (5) Color protection and hardening: After slicing, immediately put potato chips into a mixed solution containing 0.1% sodium bicarbonate, 0.2% malic acid and 0.5% calcium chloride for 30 minutes, and then soak them in 3% lime aqueous solution for 4 hours;
