Abstract
The quality improvement of the boiled-dried anchovy treated with acidic electrolyzed water (AEW) was investigated. The L value was higher in the anchovy treated with AEW than in the control. Moreover, its ΔE value was 5.08 higher than that of the control. The lipophilic browning degree was also higher than the hydrophilic degree. The degrees of calcium absorption of the control and anchovy treated with AEW were 10.77% and 12.61%, respectively. During their storage in the different conditions (five weeks in 20°C, ten weeks in 4°C, and five months in –20°C), the lipophilic browning degree of the anchovy treated with AEW was significantly lower than that of the control at the 20°C storage. The volatile basic nitrogen (VBN) content gradually increased as the storage period increased. During the 20°C storage, the content of the anchovy treated with AEW was lower than that of the control. The lipid peroxide contents increased with the storage periods, regardless of the temperature, but the content of the anchovy treated with AEW was lower than that of the control. These results indicate that AEW treatment can improve the color quality of boiled-dried anchovy and reduce its VBN and lipid peroxide contents.
