Description
Technical field
The present invention relates to food technology field, specially a kind of preparation method of dried sweet potato.
Background technology
Sweet potato, also known as sweet potato, sweet potato, pachyrhizus, sweet potato etc., it is Convolvulaceae (Convolvulaceae) sweet potato genus 1 year or many
Year raw herbaceous plant, the torrid zone, subtropical zone and the temperate zone that main producing region is located on the south 40 ° of north latitude is southern.Sweet potato nutrient enrich, except containing
Outside the nutriments such as carbohydrate, fat and protein, also containing abundant iron, calcium, phosphorus, vitamin C, vitamin B1, Hu
Radish element, niacin, lysine, tryptophan and alanine etc..With the raising and the development of science and technology of living standards of the people,
The abundant nutritive value of sweet potato and good healthcare function are increasingly by the pro-gaze of domestic and international consumer, but making
Cheng Zhong, the sweet potato dryed product of large-scale commercial is still rare, it is common that family workshop type is produced, and production technology more falls behind,
Working condition causes anxiety, and clump count is generally exceeded in product, there is more serious edible safety risk.
The content of the invention
It is an object of the invention to provide a kind of preparation method of dried sweet potato, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of preparation method of dried sweet potato, including following step
Suddenly：
A kind of preparation method of dried sweet potato, comprises the following steps：
Step 1: boiling：The sweet potato cleaned up is divided into different specifications according to Individual Quality, specification identical is red
Potato loads same steamer, fastens cabinet door, opens steam valve, the central temperature of steamer is rapidly increased to 90-100 DEG C, boiling
90-120min；Steam pressure in steamer maintains 0.4-0.6MPa；
Step 2: cutting：Cut after pachyrhizus cooling completely after removing the peel, during cutting that its is small upside down, major part
Upward, it is longitudinally cutting；
Step 3: drying：Drying machine drying is 23-25% to moisture, obtains dried sweet potato；
Step 4: freezing：By the dried sweet potato after drying, it is put into icebox and freezes 20-40min；
Step 5: thawing：The dried sweet potato of freezing is carried out into half to thaw；
Step 6: baking：The dried sweet potato that half thaws is put into apparatus for baking, dried sweet potato surface temperature is rapidly reached 95-
110 DEG C, 170-300 DEG C of baking temperature is then heated to, baking time is 1-18min；
Step 7: packaging：First carried out by the sweet potato stripe of ultraviolet-sterilization with the PET knots packaging film by ultraviolet-sterilization single
Bar knot is packed, and then wall scroll knot packaging product is carried out according to the specification of 300-500 bars/bag using PET/PE compound plastic bags
Vacuum packaging, produces tea flavour sweet potato dryed product.
It is preferred that, the sweet potato cuts the sweet potato stripe to form that size is 2.0-3.0cm × 2.0-3.0cm × 4-8cm.
It is preferred that, during the radiation sterilizing processing, the dosage of irradiation is 6kGy-10kGy.
Compared with prior art, the beneficial effects of the invention are as follows：Potato dryed product color and luster is homogeneous, keeps dried sweet potato primary colors (bright
Yellow), keeping potato Flavor, while Disinfection Effect is good, the dried sweet potato clean hygiene produced.
Embodiment
