摘要: 以金定鸭和冬瓜为原料进行煲汤,通过控制水肉比、肉瓜比、小火慢炖时间来进行单因素实验,并以感官评分为依据,对冬瓜老鸭煲的生产工艺进行响应面优化。实验结果显示:随着水肉比的上升,感官评分先升高后降低,在水肉比为2.5∶1时达到最大值。随着肉瓜比的上升,感官评分先升高后降低,在肉瓜比为1.5∶1时达到最大值。随着小火慢炖时间的增加,感官评分先急速的上升,在2h时达到最高值,然后再缓慢降低。响应面优化得到了药膳型老鸭煲的最佳工艺参数为肉瓜比1.6∶1,水肉比2.4∶1,小火慢炖时间130min,此时预测感官评分为89.66,生产验证得到感官评分为89.45。验证实验显示,在该工艺条件下制作的冬瓜老鸭煲的色泽、香味、滋味都能达到较好值,可以作为工艺化生产的基本加工条件。Abstract: Jinding duck and wax gourd was selected as the experimental materials for making soup.The study took a single factor experiment by controlling the ratio of water to meat, meat to melon, and the time of small fire to simmer.The assessment of product quality was based on sensory score, and the follow- up study used response surface methodology to optimize melon duck pot production.The results showed that:with increasing the ratio of water to meat, the sensory score elevated first and then reduced, it reached its maximum when the ratio of water to meat was 2.5∶1.With the increasing of the ratio of meat to melon, the sensory score elevated first and then reduced, it reached its maximum when the ratio of meat to melon was 1.5∶1.With the increasing in the time of a small fire to simmer, the sensory score first rapidly rised, it was the highest value at 2h, then declined slowly.The medicated duck pot optimal parameters from the response surface optimization were 1.6 (the ratio of meat to melon) , 2.4 (the ratio of water to meat) , 130min (the time of small fire to simmer) .Under these conditions, the predicted sensory score was 89.66, and the actual sensory score was 89.45.The validation experiment showed that the color, aroma and flavor of melon duck pot under the optimal conditions could achieve high value.Thus, the test results can be used as the basic processing conditions of the industrial production.
