Embodiment 1

[0019] A processing method of Jerusalem artichoke preserved fruit, the specific operation steps are:

[0020] (1) Raw material selection: choose Jerusalem artichoke with large tubers, thin skin, and less protein and fiber;

[0021] (2) Cleaning: wash the silt and dust on the skin of the selected Jerusalem artichoke with clean water;

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

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

[0024] (5) Color protection and hardening: After slicing, immediately put the Jerusalem artichoke slices into a mixed solution containing 0.1% sodium bicarbonate, 0.2% malic acid and 0.5% calcium chloride for 30 minutes, and then soak ...

Description

technical field [0001] The invention relates to a food processing method, in particular to a processing method of Jerusalem artichoke preserved fruit. Background technique [0002] Jerusalem artichoke, also known as Jerusalem artichoke, is a perennial herb of the genus Sunflower in the Compositae family. It blooms in autumn and has small yellow flowers shaped like chrysanthemums. It is usually propagated by tubers. Its underground tubers are rich in starch, inulin and other fructose polymers. They can be eaten, cooked, porridge, pickled vegetables, and dried in the sun. Dried Jerusalem artichoke can also be used as raw material for starch and alcohol production. Jerusalem artichoke has the effect of lowering blood sugar, which can promote the decomposition of sugar, convert excess sugar into heat, and improve the fat balance in the body. Jerusalem artichoke has a two-way regulating effect on blood sugar. The patient's blood sugar is elevated. Jerusalem artichoke is rich i...
