设计说明书 金银花清咽果冻的研制.pdfVIP

咽喉是个易受细菌感染的器官，并常因感冒、劳累和上呼吸道感染而 发炎 症，所以开发具有清咽功效的保健食品具有重要意义。金银花是卫生部规定的药食 同源的植物，自古被誉为清热解毒的良药，故本实验选取了金银花为主要原料，并 提取其抗菌有效成分绿原酸作为清咽功效成分，制取金银花清咽果冻。 本论文采用乙醇回流提取法提取金银花中的绿原酸，通过正交试验确定了当料 液比为 1:20 ，乙醇浓度为70% ，提取温度为60 ℃，提取时间为60min 时绿原酸的得 率最高，为5.43mg/g ；并且确定了金银花清咽果冻的最佳配方为：复配胶添加量为 1% （卡拉胶和魔芋胶的比例为4:1），白砂糖添加量为 14% 、柠檬酸添加量为0.14 ％，绿原酸添加量为0.03% ，乳酸钙添加量为0.06% ，山梨酸钾添加量为0.05% 。最 后本论文通过抑菌试验和人群试验，评定了果冻具有清咽保健功能。清咽果冻，既 方便食用，又有清咽功能，可以有效的预防咽喉疾病，具有很好的市场前景。 ：金银花；绿原酸；清咽；正交实验；果冻 I The study of honeysuckle harynx j elly Abstract T Throat is a s ecial organ, which is infected by bacterium easily. And it is often easy to inflame because of catch cold, tired and u er res iratory tract infection. So it is im ortant to develo a functional food that has the function of clearing Harynx. Honeysuckle is a “drug homologous food” lant that was ruled by the de artment of health. It is also honoured as a kind of medicine that can clear heat and detoxicat. In this ex eriment, honeysuckle is selected as the main raw material to extract chlorogenic acid that is the functional com osition of clearing Harynx. Then a kind of j elly that can clear Harynx was re ared. In this a er, the chlorogenic acid of Honeysuckle was extracted by the method of alcohol backflow. The maximum extraction efficiency of chlorogenic acid was 5.43mg/g, which was determined by orthogonal ex eriment. And the o timal conditions were material liquid ratio of 1:20, the ethanol concentration of 70%, the extracting tem erature of 60℃ and the extracting time of 60 minutes. Then the o timal formula
