This text studies antiseptic effect of refined antibacterial peptides of bullfrog skin application in meat products of low temperature,and compares the antibacterial peptides with Potassiumsorbate Nisin and related compound antiseptic on antiseptic effect.It shows that antibacterial activity of the antibacterial peptides increases with the quantity of the antibacterial peptides,and the antibacterial peptides have obvious antibacterial activity to meat products of low temperature,but antibacterial activity of the antibacterial peptides is lower than Potassiumsorbate.
