Study on The Processing Technology of Substitute Tea of Granulating Radix Puerariae Whole Powder
摘要
Abstract
[Objective and Method]A kind of substitute tea of granulating Radix puerariae(RP)whole powder was obtained by squeez-ing puffing,wet granulation with RP as the main raw material.Taking radial puffing rate and isoflavone content as the investigation index,the influence of extrusion temperature,screw speed and material moisture content on extrusion expansion effect of RP was analyzed.The extrusion puffing process was optimized by L9(34)orthogonal optimization on the basis of single-factor test.Taking sensory evaluation as the investigation index,the whole powder of RP extruded was wet granulated.[Result]The optimal extrusion puffing process were extrusion temperature 155℃,screw speed 160 r/min,moisture content of material 16%.Moreover,the most suitable process for granulation were ratio of raw material to auxiliary material,2:1,ratio of auxiliary material(maltodextrin:konjac powder),3:1,particle size 4 mm,the dry-ing methods of first low and then high(drying at 60℃for 50min and then at 170℃for 4min)was applied to prepared a kind of RP powder tea with good quality.[Conclusion]This paper can provide scientific guidance for the industrialization of substitute tea of RP powder.关键词
