This study investigated the effects of composite spices (five-spice powder and thirteen-spice powder) marinating treatment on the quality and microbial properties of ground beef.The five-spice powder and thirteen-spice powder were added to the ground beef and marinated at 4 ℃. The changes of TVB-N value and the total number of colonies in ground beef during marinating were measured. Electronic nose was used to analyze the volatile flavor substances in ground beef. The bacterial flora structure in marinated ground beef was analyzed by 16S rRNA high-throughput sequencing technique. Results showed that the two spices could significantly inhibit the increase of TVB-N value and the total number of colonies in ground beef (P<0.05), improve the flavor of ground beef and change the microbial diversity and richness of ground beef. The two spices had obvious inhibitory effect on Pseudomonas.The above results confirmed that the two spices have significant improvement effect on the quality of marinated ground beef, and the improvement effect of thirteen-spice powder is superior to that of five-spice powder.
Key words: ground beef; spices; marinating; quality improvement
