Development of the Green Tea and Soybean Cookies
Abstract:This paper mainly focus on the influence of the sensory,malleability,hardness,flexibility which affect by type and ratio of raw materials. Through experiments, the recipe for this type of cookies has finally been established. The results show that in the baking process of the green bean and soybean cookies, it produces the best outcomes when water and salt-free butter are added, and when the ratio between powdered sugar and white sugar is 2:1. This is the recipe that are best recognized (baking percentage %). Recipe: low gluten flour 100, butter 55, sugar 33, egg 18, green tea powder 1.2, soybean powder 3.5 .The required baking temperatures for the upper and down heating are 180 and 130 degree respectively; the baking period is 18 minutes. The cookies are light green color;crispy and loose;green tea and soybean flavor blend with milk flavor.And the decorative pattern is beautiful.The extension rate is 4.1, hardness is 1821.1g.

1.1 绿茶及其在饼干中的应用
绿茶是我国最早成产的茶类,遍及全国茶区,具有“绿叶清汤”、“香高醇”的品质特征,绿茶中含有茶多酚、咖啡碱、有机酸、芳香物质、多种文生素、蛋白质、游离氨基酸、多糖、矿物质、单宁等物质,其中茶多酚为绿茶中的主要成分,占干物质的20-30%[1]。现代研究表明,绿茶具有抗氧化,抗辐射,消炎抑菌,抗龋护齿,降低血脂、血糖、血压,防癌抗癌,强心利尿,消除疲劳,增进食欲等功能。 绿茶豆趣曲奇饼干的研制+文献综述:http://www.youerw.com/shiping/lunwen_11949.html
