【摘要】 以珍珠和薏米为主要原料,经过酶解、过滤、调配等工艺制得品味纯正的珍珠薏米饮料。通过正交试验,确定饮料的最佳配比,并对饮料的可溶性固形物、酸度、还原糖、金属元素、氨基酸含量等指标进行测定。结果为,饮料的最佳调配组合为:蔗糖5%,果汁20%,珍珠、薏米的比例为1:1。还原糖含量:1.4mg/mL;可溶性固形物:3.2%;pH值:5.47(15.5℃)。Zn、Mg、Fe、Mn、Na、Ca、K等7种金属元素的含量分别为0.1072μg/mL、2.1050μg/mL、0.1801μg/mL、0.1298μg/mL、163.7500μg/mL、101.8400μg/mL、26.4530μg/mL。Cd、Pb、Cr、Cu、Co等均未测出。且含有Asp、Thr、Ser、Glu、Gly、Ala、Val、Met、Ile、Leu、Tyr、Phe、Lys、His、Arg和Pro等16种氨基酸,氨基酸总含量为6.45μg/100mL。本实验制得了兼有珍珠和薏米的营养价值和保健功能的新型饮料,为珍珠和薏米的深加工开辟了一条新的途径。更多还原

【Abstract】 In this paper,pearl powder and coix seed were hydrolyzed with enzyme,filtrated and blended to produce pure taste health beverage.With the help of the orthogonal experiment,the optimal formula was assured that sugar was 5%,fruit juice was 20%,pear1:coix seed was 1:1.The properties of beverage were tested.The results showed that reducing sugar was 1.4mg/mL,the soluble solid was 3.2%,pH was 5.47 (15.5℃).The contents of metal elements of Zn,Mg,Fe,Mn,Na,Ca,K were 0.1072μg/ mL,2.1050μg/ mL,0.1801μg/ mL,0.1298μg/ mL,163.750 0μg/mL,101.8400μg/ mL,26.4530μg/ mL,respectively. There were no metal elements such as Cd,Pb,Cr,Cu and Co.The amino acids were also tested,the results showed that there were 16 kinds of amino acids,for example,Asp,Thr,Ser,Glu,Gly,Ala,Val,Met,He, Leu,Tyr,Phe,Lys,His,Arg and Pro.The total content of amino acids was 6.45μg/100mL.This new health beverage has the nutritive values and health care functions of both pearl and coix seed,which provides a new way of deep process of pearl and coix seed.更多还原
