starch sugar,potato and other agricultural products as raw materials,The most important thing is the use of biotechnology corn through the hydrolysis into production.In recent years,the technology used for glycated starch sugar production,which instead of the traditional acid method to produce sugar,to spread dipl-enzymic method and high and low pressure spray liquefaction technology.But steam pressure in domestic is low and unstable,Liquefaction process need to consume a large amount of steam.The rise of extrusion technology,provid industry of amylaceum saccharum whith a new direction of development,Extrusion technology as a short-term high-temperature materials processing methods have a wide range of applications in many fields.Yang Ming-duo,who in the expansion of cereal in the study on the extrusion of this study,and discussed the expansion of cereal mechanism,yielded extrusion technology applied to come to the food,brewing yellow wine,vinegar,liquor,starch sugar industry and theoretical basis,Practice has proved that the use and expansion technology is really a saving energy,preservation,improve the utilization of raw materials,digestibility,increase production efficiency of a new type of processing technology,has broad development prospects.Semi-dry that is Omit the traditional soaking corn,pasting,liquefied,glycosylated,and so a lot of water production process,directly from embryos used for extrusion peeled corn flour processing,the pasting, liquefied,saccharification processing were completed one step.In this study,from embryos,peeling corn flour as raw material,through orthogonal squeeze preliminary test,carry out the determination of the materials from the water,fat,protein,reducing sugar and starch content,yield the method drawn from the material DE value can be achieved in the middle inverted sugar standard conclusion.Through single factor extrusion and expansion of the comparative test,yield Obtained by squeezing approach from embryos,peeling corn flour from the DE material to achieve full value of Gongzhuling Huanglong Food Co.,liquefied feed the DE value standards.In addition,this method saved equipment investment,water and energy consumption.The results of this study are as follows:1.squeezing orthogonal preliminary test results:Moisture content of 5.5 to 8.7,0.24 to 0.50 fat content, protein content 5.1~6.5%and starch content of 5.4 to 23.5,DE value of 3.1 to 14.2.1 sample of DE value of 14.2 to Huanglong company of liquefied DE value of the 14 standards.2.squeezing single-factor test results:In circumstances of moisture content 40%,50%,extrusion temperature 150℃,160℃,and liquefied volume of 0.4%,0.6%and 1.0%,1.2%of Glucoamylase,1 sample moisture content for:8.0%,DE value of 40.2;sample moisture content for:9.0%,DE value of 39.5.3.expanded single-factor test results:In circumstance of moisture content of 15%,20%,25%,30%, extrusion temperature 130℃,and liquefied volume of 0.4%,0.6%,0.8%,1.0%,glucoamylase of 0.6%,0.8%,1.0%,1.2%,1~# Expanded materials for water content:3.8%,DE value of 25.4;2# Expanded materials for water content:4.9%,DE value of 25.9,3~# Expanded materials for water content:6.7%,DE value of 27.6, 4~# Expanded materials for water content:8.3%,DE value of 29.7.4.by contrast single-factor test results come after the extrusion materials DE value far higher than the expansion of the materials after DE value,and the expand effect does not meet the standard DE value.5.After energy expenditure calculation,draw on the research save water 1.9×10~6 tons and power-saving 1.0×10~9 kilowatt hours each year than Dacheng company.And reduce environmental pollution.Save the jet liquefaction equipment investment,economic efficiency is very impressive.
