Embodiment 1

[0019] A processing method for crisp sweet potato chips, the specific operation steps are:

[0020] (1) Peeling: select ripe and fresh sweet potatoes without mechanical damage, and peel them for later use;

[0021] (2) Slicing: put the raw material in a slicer and cut into thin slices of 5-8mm;

[0022] (3) De-starch: Put the cut sweet potato slices into 60°C water for de-starch treatment;

[0023] (4) Sugar stain: use 35% sucrose, 10% fructose, 5% seabuckthorn juice and 3% maltose to prepare a sugar solution with a concentration of 56%, pour sweet potato slices into the sugar solution and soak for 26-28 hours;

[0024] (5) Freezing: Take the sweet potato slices out of the sugar solution, drain them, and place them in the freezer for freezing;

[0025] (6) Vacuum frying: Use a closed vacuum frying kettle to draw out the air in the kettle until it is close to a vacuum state, heat the oil in it to boiling, and then put the frying cage with sweet potato chips into the vacuum fr...

Abstract

The invention discloses a processing method for crisp sweet potato chips and belongs to the field of food processing. The processing method is characterized in that the processing technological process of raw material selecting, sorting, peeling, cutting, starch removing, sugar steeping, freezing, vacuum frying, centrifugal oil removing, cooling, weighing and packaging is adopted. The processing method has the advantages that the crisp sweet potato chips are golden in color, crisp in texture, not soft, fragrant, crisp and tender in taste, have the special fragrance and sweetness of sweet potatoes and the faint scent of roses and are crisp and delicious; the crisp sweet potato chips are beneficial to improving the immunity of the human body and maintaining and conditioning functions of the human body, further have the effects of preventing osteoporosis, resisting senescence and preventing atherosclerosis, and is rare food which is low in calorie, sugar and fat.

Description

technical field [0001] The invention relates to a food processing method, in particular to a processing method of crispy sweet potato chips. Background technique [0002] Sweet potato, a herbaceous vine, is an annual or perennial vine herb, also known as sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, and has different names due to different regions. Its vines are slender, its stems crawl on the ground, and its roots produce lactic acid through anaerobic respiration; its skin is whitish or red, and its flesh is mostly yellowish white, but also purple. In addition to eating, it can also be used as a raw material for sugar and wine making. [0003] The role of sweet potato: 1. Enhance immune function: sweet potato contains a lot of mucus protein, which can prevent the atrophy of liver and kidney connective tissue, improve the body's immunity, and prevent collagen diseases; the minerals contained in sweet potato play a role in m...
