Royal jelly,secreted by the sublingual and mandibular glands of nurse worker bees,is a kind of milky white or yellow emulsion.In the present trial,the antibacterial effect of royal jelly on meat was investigated,and the TVB-N value and the Colony Forming Units(CFU) in pork were determined.The result demonstrated that the TVB-N value and CFU in pork stored at 4℃ for 6 days were inhibited obviously with royal jelly at the concentration of 0.01 ～ 0.1 g/mL.The TVB-N value in pork was less than 15 mg/100 g,and the CFU were less than 1 × 104 CFU/g.During the low temperature storage,the Royal Jelly can effectively extend the shelf life of pork.
