| 摘要: |
| 研究了菊花、百合花、玫瑰花、金银花、挂花、红花、苹果花、木槿花、啤酒花的成分。结果表明，各种干花原料的蛋白质含量较高，均在100 mg/g以上，啤酒花的蛋白质含量达217 mg/g，除金银花不含色氨酸外，其余几种花均含18种氨基酸，包括人体所必须的8种氨基酸，木槿花中谷氨酸含量最高，达36.34 mg/g。矿物质营养丰富，在苹果花、红花中铁的含量分别达1.32，2.4 mg/g。玫瑰花汁提取工艺为：第1次用15倍的水在45 ℃提取2 h，第2次用10倍的水在70 ℃提取1.5 h，第3次用10倍的水在95 ℃提取1 h，合并提取液，硅藻土过滤提取液后可溶性总糖损失率高达72.7％，总酸几乎没有损失，单宁和粗蛋白均有一定损失。玫瑰花饮料的配方为：花汁120 mg/g，蔗糖80 mg/g，柠檬酸2.2 mg/g，柠檬酸三钠0.4 mg/g，磷酸三钠0.7 mg/g，乙基麦芽酚20 μg/g，玫瑰香精1 mg/g，其他辅料和口味改良剂适量。 |

| Abstract: |
| Composition analysis of Safflower,Honeysuckle,Rose,Chrysanthemum,Sweet-scented osmanthus,Rose of Sharon,Apple flower,Lily were conducted.It shows that protein content of several dry flowers is more than 100 mg/g,protein content of Hops is 217 mg/g.Several dry flowers have 18 kinds of amino acid and essential amino acid,but Honeysuckle has not.Trp,Glu of Rose of Sharon is 36.34 mg/g.Several dry flowers have rich mineral composotion.Iron of Safflower is 2.4 mg/g.Iron of Apple flowers is 1.32 mg/g.The Extract technolgical parametes of rose flower juice were studied.Firstly,15 times water and 0.2 μg/g of pectolase were add to flowers,at 45 ℃,taking time for 2 h.Second,10 times water 95 ℃,taking time for 1 h.Then,diatomaceous earth was useed to filter rose floer juice together with three times estract juice.Soluble toatal sugar lost 72.7%,total acid did not change,tannin and protein lost.The optimal ingredients for rose beverage are 120 mg/g of rose flower juice,80 mg/g of sugar,2.2 mg/g of Lemon acid,0.7 mg/g of Sodium phosphate tribasic,0.4 mg/g of Sodium lemon acid,1 mg/g of Rose flauouring,20 μg/g of Ethyl maltol,with proper proportion of others to improve its taste. |
