浙贝母花-宁海白枇杷花保健饮料的研制及其止咳作用

Production of healthy beverage of Fritillaria thunbergii flower and Ninghaibai loquat flower and evaluation of its cough relieving effect

以浙贝母花和宁海白枇杷花为原料,研制保健饮料并评价其止咳功能。通过正交设计,确定浙贝母花最佳提取工艺为加12倍量水,提取时间2 h,提取3次;宁海白枇杷花最佳提取工艺为加9倍量水,提取时间1.5 h,提取1次。通过正交设计和感官品质评价,确定保健饮料的最佳配方为:浙贝母花提取液160 g/L,宁海白枇杷花提取物40 g/L,木糖醇40 g/L、柠檬酸0.5 g/L、蜂蜜35 g/L和果胶3 g/L。经测定,饮料中总生物碱含量为0.12 mg/m L,总黄酮含量为0.40 mg/m L,各项指标均符合相关规定。采用小鼠氨水引咳实验和豚鼠枸橼酸引咳实验对产品的止咳功能进行评价,表明其有显著的止咳作用(p<0.05)。该饮料保健性能突出、风味独特、质量符合相关标准,可用于咳嗽类疾病的辅助治疗。

Fritillaria thunbergii flower and Ninghaibai Loquat flower as raw materials,a kind of health beverage was developed and its cough function was also evaluated. By orthogonal experiment design,the optimal extraction process of Fritillaria thunbergii flower and Ninghaibai Loquat flower were determined.The optimum process were to add water 12 times,extract 2 h,extract 3 times; and to add 9 times water,extract 1.5 h,extract 1 time,respectively. Through orthogonal design and sensory quality evaluation,the results indicated that optimal technical conditions were： the Fritillaria thunbergii flower extract 160 g/L,the Ninghaibai Loquat flower extract 40 g/L,xylitol 40 g/L,citric acid 0.5 g/L,honey 35 g/L and pectin 3 g/L. Total alkaloid content in the beverage was as follows： 0.12 mg/m L,meanwhile total flavonoids content was 0.4 mg/m L. All indicators were in accordance with relevant regulations.The cough relieving effect were studied by ammonia water causing cough in mice and citric acid causing cough in guinea pigs.The results showed that there was a significant cough effect（ p 0.05）.The beverage had healthy function,unique flavor,and met the related standards,which could be used for the adjuvant treatment of cough diseases.
