Effects of Alkaline Electrolyzed Water Partial Substitution of Complex Phosphate on the Quality of Dosidious gigas
Objective:This study aimed to investigate the effect of partial substitution of complex phosphate by alkaline electrolyzed water on the quality of Dosidious gigas.Methods:The effects of soaking gain rate,freezing loss rate,thaw-ing loss rate,cooking loss rate,water holding capacity,pH value,hardness,color difference,tissue structure and sen-sory evaluation of Dosidious gigas were measured within 0,30,60,90 and 120 days.Results:The sensory scores of alkaline electrolyzed water and complex phosphate solution treatment(MIX)were better.The soaking weight gain rates in the MIX treatment group were(7.53±0.31)％,which increased by about 1.18％,2.90％and 3.97％compared with alka-line electrolyzed water treatment(AEW),complex phosphate treatment(CPH)and water treatment(WAT).In terms of total chromatic aberration,the AEW group outperformed the CPH group and the MIX group(P＜0.05).In terms of tissue structure,after freezing,the tissue texture of squid in AEW group and MIX group was clear,evenly arranged and com-pact,while the muscle fibers of WAT group and blank(NOT)group were obviously scattered,and the degree of dam-age was more serious.There was no significant difference between freezing loss and thaw loss(AEW,CPH,MIX),and the soaking weight gain rate of the MIX group[(7.53±0.31)％]was significantly higher than that of AEW[(6.35±0.24)％]alone and CPH[(4.63±0.30)％]alone,while the hardness was significantly reduced.The cooking loss rate of the AEW group and the MIX group was significantly lower than that of CPH alone.Conclusion:The use of AEW or MIX can be used to improve the quality of Dosidious gigas and provide feasible technical conditions for future storage and preservation methods of Dosidious gigas.
