REFRIGERATED STORAGE (2 DEGREES-C) OF SOLE (SOLEA-SOLEA) FILLETS UNDER CO2-ENRICHED ATMOSPHERES

Microbial (total viable, Brochothrix thermosphacta, lactobacilli, and Enterobacteriaceae counts), biochemical [pH, total volatile nitrogen, nucleotide breakdown products, D(-) and L(+) lactic acid, and short-ch ain fatty acids], and sensory attributes (color and odor) of refrigera ted (2 degrees C) sole (Solea solea) fillets under CO2-enriched [CO2/a ir (20/80) (v/v) and CO2/air (40/60) (v/v)] atmospheres were determine d. Sensory results showed shelf life extension of 4 and 8 days for 20 and 40% CO2-enriched atmospheres, respectively. Microbial and biochemi cal results revealed that the 40%CO2-enriched atmosphere was the most effective package type for refrigerated sole.
