Abstract: In this study, minced beef bone(the mass ratio of bone to meat is 3∶7)was used as raw material. Traditional, spicy and fermented beef flavor were prepared by hot-pressing extraction and enzymatic hydrolysis followed by Maillard reaction with adding potassium sorbate in beef flavor as control group. The pH value, water activity and brightness of beef flavor were measured during storage at 4 ℃ and 20 ℃. The results showed that the pH values of BF with spices were different from those of other groups, and the changes of brightness and water activity were the same among the six groups. The shelf life of the beef flavor can reach 2.5 months and 40 d at 4 ℃ and 20 ℃, respectively. After modification, the product was stratified obviously.
