Physical, chemical and sensory evaluation of sardines (Sardina pilchardus (Walbaum, 1792)) stored at no-frost conditions
Abstract
In this study, sensory, chemical, and physical analyses were carried out on sardines (Sardina pilchardus) as fresh and cleaned, during 140 days of storage at no-frost conditions. pH as physical criteria which determine quality of frozen fish meat, thiobarbyturic acid (TBA) mg malonaldehyde/ kg sample, total volatile base nitrogen mg N/100 gr sample and formaldehyde (FA) as criteria which determine enzymatic, biochemical and microbiology deterioration of fish and also sensory criteria as color, odour, taste, consumption value and texture firm were considered. During storage, the means of pH, TBA, TVB-N, free FA(ex) and free and bound FA(dest) values were 6.41-6.53, 0.50-4.76 mg malonaldehyde/kg sample, 16.8-21.0 mg N/100 gr sample, 1.74-2.39 mg FA(ex)/kg and 0.66- 1.55 mg FA(dest)/kg, respectively. At the end of this study, the critical value of chemical and physical quality criteria were not reached. However, the values of results obtained in sensory analyses were rapidly improved than value of physical and chemical analyses in the evaluation of quality.
