Abstract
Pearl powder and coix seed were hydrolyzed with enzyme,filtrated and blended to produce pure taste health beverage.With the help of the orthogonal test,the best formula was that sugar was 5%,fruit juice was 20%,pearl:coix seed was 1:1.The properties of beverage were tested.The results showed that reducing sugar was 1.4 mg·mL-1,the soluble solid was 3.2%,pH is 5.48(15.5 ℃).The contents of metal elements of Zn,Mg,Fe,Mn,Na,Ca,K were 0.107 2,2.105,0.180 1,0.129 8,163.75,101.84,26.453 μg·mL-1,respectively.There were no metal elements such as Cd,Pb,Cr,Cu and Co.There were 16 kinds of amino acids in the beverage,Asp,Thr,Ser,Glu,Gly,Ala,Val,Met,Ile,Leu,Tyr,Phe,Lys,His,Arg and Pro.
