Abstract
The present invention relates to technical field of agricultural product process, and in particular to a kind of processing method for preventing dried sweet potato from producing hickie, specific steps include（1）To be peeled after sweet potato washing, be put into digester boil it is ripe to 78 points；（2）Sweet potato after boiling is cut into sweet potato stripe, is placed in the soak containing sodium benzoate and edible glycerol and boils 3 5min；（3）By step（2）It is 26% 28% that obtained sweet potato stripe is dried to water content after being cooked with steam, obtains dried sweet potato；（4）It is put into after dried sweet potato is cooled down in the refrigerating chamber that temperature is 5 10 DEG C and freezes 40 60min；（5）Sweet potato stripe after freezing is vacuum-packed.The present invention carries out boiling dried sweet potato using sodium benzoate and edible glycerol as soak, is advantageous to the shelf-life of extension high moisture content dried sweet potato, makes that the sweet potato dryed product taste produced is more delicious, product is safer；Dried sweet potato is freezed before packing simultaneously, hickie is produced so as to avoid dried sweet potato from separating out sugar crystallization, reduces the possibility that dried sweet potato produces hickie.
Description
Technical field
The present invention relates to technical field of agricultural product process, and in particular to a kind of processing side for preventing dried sweet potato from producing hickie
Method.
Background technology
Sweet potato contains the bioflavonoid composition of uniqueness, and defecation can be promoted unobstructed, can effectively suppress breast cancer and colon cancer
Generation；The function of digestive organs can be improved, it is nourishing liver and kidney, it is possibility to have effect treatment hepatitis and jaundice.Dried sweet potato is sweet potato depth
One of series of products are processed, there is the advantages of sweet tea is soft tough fragrant, nutritious, and farthest remain original wind of sweet potato
Taste, it is loved by consumers, there is very big market development potential.But in sales process is stored, dried sweet potato surface can produce
The spot of raw white, influences product appearance quality, reduces the sales volume of dried sweet potato.Therefore, it is necessary to research and develop a kind of simple, quick
Method prevents or reduced the generation rate of dried sweet potato white patches on surface, and on the basis for ensureing safe mass, protects to greatest extent
Hold nutrition, the flavor and taste of product.
The content of the invention
In order to solve the above problems, the invention provides a kind of processing method for preventing dried sweet potato from producing hickie, specific skill
Art scheme is as follows：
A kind of processing method for preventing that dried sweet potato from producing hickie comprises the following steps：
（1）It will be peeled after sweet potato washing, be put into digester that to boil 7-8 point ripe；
（2）By step（1）Sweet potato after boiling is cut into sweet potato stripe, is placed in the soak containing sodium benzoate and edible glycerol and boils
3-5min；
（3）By step（2）It is 26%-28% that obtained sweet potato stripe is dried to water content after being cooked with steam, obtains dried sweet potato；
（4）It is put into after dried sweet potato is cooled down in the refrigerating chamber that temperature is 5-10 DEG C and freezes 40-60min；
（5）Sweet potato stripe after freezing is vacuum-packed.
Further, the step（2）In sweet potato stripe thickness be 1-2cm.
Further, the step（2）Soak in the concentration of sodium benzoate be 0.25%-0.3%, edible glycerol it is dense
Spend for 0.55%-0.7%.
Further, the step（2）The temperature of middle soak is 90-100 DEG C.
Further, the step（5）In dried sweet potato be put into microwave disinfection or ultraviolet before vacuum packaging irradiated
Sterilize 4-8min.
Further, the step（5）In vacuum-packed packaging bag be by ultraviolet-sterilization PET/PE compound plastic bags.
Beneficial effects of the present invention are：
The present invention carries out boiling dried sweet potato using sodium benzoate and edible glycerol as soak, and it is red to be advantageous to extension high moisture content
The potato dry shelf-life, make that the sweet potato dryed product taste produced is more delicious, product is safer；Dried sweet potato is entered before packing simultaneously
Row freezing, hickie is produced so as to avoid dried sweet potato from separating out sugar crystallization, reduces the possibility that dried sweet potato produces hickie.
Embodiment
In order to be better understood from the present invention, with reference to specific embodiment, the invention will be further described：
Embodiment 1：
