Embodiment 1
[0032] 1. Selection of raw materials: Sweet potatoes are required to be harvested before the frost period. Choose fresh potatoes with smooth and tender skin, no wormholes, no disease spots, no tatters, no peculiar smell, and 100-500 grams in size as raw materials;
[0033]2. Storage and saccharification treatment: put fresh potato pieces into ventilated plastic baskets, stack them on top of each other in a cool and ventilated place indoors, store at a room temperature of 12°C, and store for saccharification for 15 days.
[0034] 3. Cleaning: Wash the soil on the surface of fresh potatoes with clean water, and a fruit and vegetable cleaning machine can be used.
[0035] 4. Peeling: manual or mechanical peeling.
[0036] 5. Cut into strips: Cut the cleaned sweet potatoes into long strips of about 2.5cm×2.5cm×5cm by hand or mechanically.
[0037] 6. Blanching: Blanch in hot water at 80°C for about 30 seconds to inhibit the enzyme activity of sweet potatoes, and drain after blanc...

[0049] Process flow see attached figure 1 , see embodiment 1 for the detailed process. Fresh potatoes→storage at 15°C and saccharification for 10 days→cleaning→peeling→cutting into strips→blanching in hot water at 85°C for 20s→draining→adding honey with 1% of the dry mass of sweet potatoes→steaming for 30 minutes at a time→microwave vacuum drying at 60°C once ( Simultaneously sterilized) to a moisture content of 35% → add camellia oil of about 0.3% of the dry mass of sweet potatoes → steam for a second time for 30 minutes → secondary microwave vacuum drying at 50°C (simultaneously sterilized) to a moisture content of 18% → store in a cold storage at 4°C Moisturize for 5 days until the moisture content is 24% → Microwave sterilization at 30°C for 3 minutes → Vacuum small packaging.
[0050] The resulting dried sweet potato product is brownish-red, shiny, has the proper potato flavor of this variety, and has a pleasant sweetness. After inspection, the total number of bacteria i...
