Abstract:
This study was carried out to evaluate the lipid oxidation and sensory attributes of anchovy marinated with 10% NaCl+4% alcohol vinegar+0.2% citric acid solution and 0.1% different essential oils. Group A Control: only sunflower seed oil, Group B: sunflower seed oil+0.1% rosemary oil, Group C: sunflower seed oil+0.1% coriander oil, Group D: sunflower seed oil+0.1% laurel oil and Group E: sunflower seed oil+0.1% garlic oil. During storage, lipid oxidation as indicated by the 2-thiobarbituric acid reactive substances (TBARs) values of the control group were significantly higher than the other groups containing essential oils. The results showed that the essential oils have retarding effect on lipids oxidation. This effect was the highest in laurel oil during initial 3 months; and it was similar to laurel oil and rosemary oil in the fourth month; in all the essential oil added groups in 6 month. L*(brightness) values were similar for all groups in first fourth months but, at the last 2 months, group using laurel oil was found better. Yellowness (b*) was similar in all groups during the intial 3 months whereas, after that lower values in the groups that used laurel and rosemary oils were detected. The study concluded that marination with 0.1% laurel oil of anchovy can retard lipid oxidation and improve the sensory attributes of the product during refrigerated storage.

Relative Reactivity of Carboxylic Acid Derivatives
A key factor in assessing the reactivity of the acid derivatives is the basicity of the substituent or the leaving group. The lower the basicity of the leaving group, the higher the reactivity of the derivative. The basicity of the leaving group follows this order:
Halide ions < Acyloxy ions < Alkoxy ions < Amine ions
