On this research have observed liquid smoke’s ability to pursue microbe activity, antimicrobe and antioxidant compounds in betel oleoresin, give preservation effect by pursue microorganism’s growth on Chanos-chanos forsk. Fish Submerge process by liquid smoke with betel oleoresin submerge on pre-smoking, give optimum result value of TVB 8,62 mg N/100gr, reach on submerge by betel oleoresin 6% concentration, during 15 minutes, and submerge with liquid smoke 4% concentration during 10 minutes. Value of total microbe 6,06 x 10 3 CFU. Result above has contribution with censor examination of rather hard texture and much liked flavor
