Description
Technical field
The invention belongs to food processing fields, and in particular to a kind of puffing with superheated steam prepares high adsorption cornstarch
Method.
Background technology
The defects of native starch is low, poor, mechanical resistant is poor by film property because of solubility significantly limits answering in the industry
With, therefore its certain performance is promoted often through starch conversion, expand its application range.High adsorption starch be it is a kind of have than
Surface area is big, absorption property is good, particle surface has a kind of modified starch products of partial pore.For unstable, oxidizable
Active material, using high adsorption starch adsorption can protect its functionality, avoid occur oxidation, decompose, can also cover up
Smell, color and taste can also be applied to biological medicine, chemical field not only in food processing field extensive application, tool
There is good development prospect.
The method for preparing high adsorption starch at present mainly has Physical, chemical method and bioanalysis.Chemical method generally uses
Acid（Such as hydrochloric acid etc.）Stoichiometric number ten hours at a certain temperature, low since there are reaction rates, time-consuming, reaction process is multiple
Miscellaneous, the problems such as randomness is strong, and product structure obtained is fragile, stability is not strong, it is difficult to applications well in the industrial production.Biology
Method mainly uses the enzyme preparations such as alpha-amylase, isoamylase, Pullulanase, carbohydrase to produce high adsorption starch, need to usually adopt
With higher product absorption is improved with enzyme amount, extension reaction time or Aided Physical method such as mechanical treatment, heat treatment etc.
Performance and yield, technique is more complex, and production cost is higher.Physical generally has spray drying process, mechanical impact etc., usually only exists
Starch surface forms corrosion or pit, product absorption property obtained are limited.Therefore, Physical is generally more difficult to industrial applications,
It is intended only as preparing the householder method of high adsorption starch.Puffing with superheated steam method is a kind of to be evenly distributed on inside particle
Superheated steam is that medium carries out instantaneous pressure release to reach the puffing new technique means of material.In the rank of superheated steam heated material
Section can make material steep temperature rise, fractions change since the heat-flash of steam acts on；When moment pressure release, inside material
Superheated liquid flash evaporation, the steam being evenly distributed on inside material discharge rapidly, it will generate powerful shock wave so that object
Material generation is puffing, and material structure is destroyed, and loose porous structure is formed.
Common corn starch source is wide, cheap；Cornstarch crystalline texture is A types, and better heat stability is processing
The quality material of high adsorption starch.The present invention provides new method for extraordinary starch exploitation, has extensive theoretical direction and reality
Trample meaning.
