ANGELES, MARITES FENOMENO. Cavite State University, Indang Cavite. April 2001. " Evaluation of Spoilage Patterns of Hot Smoked Tilapia (Oreochromis niloticus)". Adviser: Mr. Francisco M. Heralde HI. A study was conducted to evaluate the spoilage patterns of hot smoked tilapia. Specifically, it aimed to evaluate the sensory characteristics, the pattern of microbial growth, and the nutritional composition and peroxide value of hot smoked tilapia over a period. The previously standardized smoked products of Bernardo (2001) used in the study were: Treatment 1 (1 hr. salting, 2 hrs. smoking) and Treatment 2 (2 hrs. salting, 3 hrs. smoking). Samples were packed in polyethylene bags at ambient temperature. Data were analyzed using T-test and analysis of variance (ANOVA). Mean scores were compared using Duncan's Multiple Range Test (DMRT). Sensory evaluation showed that there was no significant differences between treatments on the of degree of disintegration, surface color, surface texture, and glossiness of hot smoked tilapia on all sampling days. All the sensory attributes were not obtained on the fourth day. Three days was found as the limit of shelf life for hot smoked tilapia because it was the borderline of acceptability for the different quality attributes. Sensory evaluation was not conducted beyond three days of storage because the smoked samples in both treatments were no longer edible to the panelists due to marked spoilage. Growth of bacteria and molds were found rapid at ambient temperature. Treatment 2 had lesser microbial growth than Treatment 1. Microbial load could not be counted beyond three days due to massive microbial population. Results of the nutritional composition analysis showed that there was a decrease in moisture, ash, fat, and protein contents through time. These changes conformed with the physical and sensory changes of the samples. Peroxide value showed gradual increase through time.
