Abstract:
The whole process of "zero metal addition" was realized by using fresh eggs as raw materials to prepare egg and egg, and using different stages to change the concentration of alkali in the mixture. On the basis of analysis in the process of curing material liquid alkali concentration, rheology, color, quality and structure characteristics of goose eggs as time changes, such as optimizing the goose egg processing technology, to achieve the goose egg color of light transparent appearance sensory effects. The results showed that the different curing material liquid alkali concentration changes significantly, the higher the material liquid alkali concentration, the greater the relative egg white alkali concentration, the first phase of material liquid alkali concentration was 3%, 4%, 5%, the results showed that the color of the eggs was the fastest. Egg color changes, quality and structure characteristics and material liquid alkali concentration was significant, whiteness value after the replacement of material liquid alkali concentration, 4% and 1% for 30 d peak. The alkali concentration had a great effect on the hardness of eggs, and there was no significant difference between cohesion and viscosity. Conclusion:The best process of adding the eggs to the preserved eggs was as follows:the eggs were preserved in NaOH solution with concentration of 4% for 14 days, and the NaOH solution with 1% concentration of 1% was picked again for 25 days.
