Abstract: The experiment was conducted to study the effect of different storage temperature and time on freshness,composition,egg quality and albumen transparency of pigeon eggs,in order to discuss optimal storage condition of pigeon eggs,and explore the change rule of pigeon albumen transparency under different storage conditions,finally provide the theoretical basis for reasonable storage and sale of pigeon egg.1-2 year old White King pigeons with male-female pairs were chosen as the experimental object,3 (low temperature,middle temperature,high temperature)×4 (1w,2w,3w,4w) was designed.90 pigeon eggs were randomly collected each week,and were placed under three different temperatures for 1,2,3 and 4 weeks respectively,30 eggs each group.The freshness,composition,egg quality and albumen transparency of pigeon eggs were determined.The results showed that there was no scattered yolk or mildew after storing for 4w under low temperature,but the pigeon eggs could only be stored for 1w without deterioration under middle and high temperature.As time went on and the temperature went up,the egg weight loss rate showed a significant upward trend (P<0.05).The storage time had a significant effect on the eggshell rate,the albumen rate and the yolk rate (P<0.05),but the storage temperature had no effect on the three abrove indexes (P>0.05).The storage time and temperature had significant effects on the albumen height and yolk color (P<0.05).The albumen height showed the downward trend,and the yolk color darkened as time went on and the temperature went up.There were significant effects of the storage time and temperature on L*,a* and b* values of cooked pigeon albumen (P<0.05).The percentage of transparent pigeon eggs was the highest under middle temperature.In conclusion,pigeon eggs should be stored and sold under refrigeration,and pigeon eggs could be stored for more than 4 w in cold storage condition.The albumen transparency of pigeon eggs could be improved under middle temperature (about 20℃).

Key words: storage condition; pigeon egg; freshness; composition; egg quality; albumen transparency
