Description

A kind of processing method of dried sweet potato

Technical field

the present invention relates to the production method of food, especially a kind of processing method of dried sweet potato.

Background technology

area, Feng County, Jiangsu is the flat-bottomed land of washing away, depositing and form after changing its course in ancient the Yellow River, soil layer is all that thousands of kilometer washes away the alluvials such as mud fine sand stone of getting off and forms from ancient the upper reaches of the Yellow River, the husky earth layer of soil property, gas permeability is good especially, be rich in various mineral trace elements and various organic and inorganic nutrients fertilizer that plant growth needs in soil layer, so soil is very fertile.In addition, the Feng County local climate is warm, makes a clear distinction between the four seasons, and sunshine, abundance was applicable to the growth of growth, the especially Ipomoea batatas of crops very much.

ipomoea batatas contains abundant starch, dietary fiber, carrotene, vitamin A, Cobastab, vitamin C, vitamin E and potassium, iron, copper, selenium, calcium etc. more than 10 plants trace element, nutritive value is very high, by nutritionists, is called the most balanced health food of nutrition.Ipomoea batatas can keep blood vessel elasticity, and control the elderly habitual constipation is had to remarkable result.The eating method of Ipomoea batatas is a lot, can eat something rare, cooks congee, fry, and also can make dried sweet potato.But traditional dried sweet potato taste is single, and fresh Ipomoea batatas can be subject to accumulating, keeping, temporal restriction when selling, if the time passes Ipomoea batatas of a specified duration, will rot to go mouldy, and the peasant will be subject to serious economic loss.Therefore, the shelf-life that how to extend Ipomoea batatas becomes the key that improves the peasant economy income.

Summary of the invention

for the taste and its economy of raising, edibility that improves Ipomoea batatas, the invention provides a kind of processing method of dried sweet potato, the method simple possible, safety and sanitation, the dried sweet potato processed is of high nutritive value, instant, not only played important popularizing action to the Feng County Ipomoea batatas, but also improved agriculture benefit and the economic benefit in area, Feng County.

the technical solution adopted for the present invention to solve the technical problems is: the processing method of dried sweet potato is,

(1) selected high-quality Ipomoea batatas is removed the peel with skiving machine, and then cut into slices with slicer, sweet potato slices thickness is 2mm～4mm;

(2) sweet potato slices is put into to the blanching of boiling water pot 1 minute～10 minutes, and then it is cooling to put into cold water;

(3) cooled sweet potato slices is put into to cider immersion, seasoning, at room temperature soak 0.4 hour～0.6 hour, the fragrant and sweet flavor of apple is infiltrated in Ipomoea batatas to regulate the taste of Ipomoea batatas, and the high-quality red fuji apple that cider is chosen the large Shahe Area plantation in Feng County squeezes;

(4) sweet potato slices individual layer balance, stay the gap of 1cm between sweet potato slices, balance is placed on the baking rack that can hold 5 layers of balance, layer with layer the balance spacing be 10cm, then baking rack push in tunnel oven take the temperature of 50 ℃～70 ℃ cure 5 minutes～10 minutes to contained humidity in sweet potato slices be 40%～60%;

(5) dried sweet potato of oven dry is taken out from baking oven, pack with the packing machine inflated with nitrogen, then put into warehouse for sale.

the invention has the beneficial effects as follows, the processing method simple possible of this dried sweet potato, safety and sanitation, the dried sweet potato processed is of high nutritive value, instant, can improve the taste of Ipomoea batatas, not only the Feng County Ipomoea batatas played to important popularizing action, but also improve agriculture benefit and the economic benefit in area, Feng County.
