高温高压法提取牛骨素工艺研究

Study on Extraction Technology of Bovine Ossein by High Temperature and High Pressure

试验以鲜牛骨为原料,对高温高压提取牛骨素的工艺条件进行了研究。通过考察提取温度、提取时间、料液比、粒度大小四个主要因素,设计单因素和正交试验,得出高温高压法提取牛骨素的优化工艺条件,结果表明:提取温度140℃,提取时间140min,料液比(质量)1∶4,粒度大小约2cm,牛骨素出品率能够达到最好的水平。

In this paper,the bovine bone is chosen as raw material,the optimal technological condition for extracting the flavor materials from bovine bone by high-temperature and high-pressure technology is studied.The main parameters,such as the extraction temperature,extraction time,material-fluid ratio and particle size are studied by single factor experiment and orthogonal experiment.The optimum conditions of extraction are as follows：the extraction temperature is 140℃,extraction time is 140 min,material-fluid ratio is 1∶4,and the particle size is about 2cm.
