Abstract

This study aimed to determine the best concentration levels of ozonation and storage time in maintaining the quality of tilapia fillet meat based on chemical characteristics, microbiology and organoleptic quality. This research was conducted in an experimental laboratory using a randomized factorial block design (RAKF) with 2 treatment factors for variations in ozone levels (A) used at 0 ppm; 0.5 ppm; 2.5 ppm and 4 ppm and storage time (B) 0 days, 14 days and 21 days were repeated 2 times. The parameters observed in this study included chemical analysis, namely TVB (mgN/100g) and TMA (mgN/100g) tests, microbiological characteristics, namely Total Plate Count (CFU/mL) levels. Sensory analysis includes appearance, smell and texture characteristics. The results showed that the treatment of ozone levels, storage time and interaction had a significant effect on the chemical and microbiological characteristics of tilapia fillets. The results of the hedonic quality test showed that the treatment of ozonation levels and storage time had a significant effect on appearance, texture and odor. Based on the results of chemical analysis which included TVB and TMA tests and also from the results of microbiological analysis, namely the TPC test, it can be concluded that at 21 days of storage, the ozonized level was 0 ppm; 0.5 ppm; 2.5 ppm; and 4 ppm tilapia fillets have decreased in quality but are still suitable for consumption because they have not passed the acceptance limit for consumption.
