PURPOSE: Provided are process methods of ice cream containing antibacterial undiluted solution extracted Pinaceae and Cryptomeriaceae and ice cream containing antibacterial undiluted solution including lactic acid bacteria, and each ice cream prepared hereby. Therefore, the prepared ice cream has a prevention effect on the growth of harmful enteric bacteria. CONSTITUTION: The process method of ice cream containing antibacterial undiluted solution extracted Pinaceae and Cryptomeriaceae comprises the steps of: drying antibacterial plants in the shade then drying them in the sun; adding to the dried plants a functional solution two times as mush as them and heating them; cooling and collecting the vapor generated by heating to obtain antibacterial undiluted solution; adding the antibacterial undiluted solution to ice cream then followed by heating , dissolving and mixing them; homogenizing the mixture under the pressure of 120kg/cm¬3; sterilizing the homogenized mixture at 90 deg.C for 20 seconds; aging the sterilized mixture at 5 deg.C; quick freezing the aged mixture at -45 to -60 deg.C; and filling the quick frozen mixture into a container, wherein in the case of ice cream containing antibacterial undiluted solution including lactic acid bacteria, Lactobacillus is further inoculated into the quick-frozen mixture before filling.
