Abstract:In order to improve the value of buffalo raw meat and develop diversified characteristic products，Yunnan buffalo was used as raw material to make sand tea roast water beef.The process optimization of baking temperature，baking time，sand tea sauce addition and sesame sauce addition was carried out，and the difference between the three analysis and evaluation methods was compared by using extreme difference analysis method，principal component analysis method and fuzzy mathematics method.The optimum production formula and technology of roast beef with sand tea were obtained by comprehensive evaluation.The results showed that the optimal processing parameters were obtained by range analysis，principal component analysis and fuzzy mathematics.The optimal processing parameters were170℃，25min，6%，2.5%；170℃，25min，5%，2.5%；150℃，25 min，6%，2%，respectively.The optimum formulation technology of sand tea roast water beef was as follows：baking temperature 170℃，baking time 25 min，sand tea sauce 6%，sesame sauce 2.5%.Three different analytical methods were used to analyze the rationality and shortcomings of sand tea roast beef in different treatment groups，and the rationality of the results could be improved by combining the three evaluation methods.
