Efectos del método y duración del almacenamiento, sobre la calidad del huevo del caracol gigante africano (a. Marginata)

摘要

Seventy five giant African land snails were used to investigate the effect of method and length of storage on snail egg quality. Snail eggs were stored either in fridge (cold), in a container on a shelf (ambient) or in earthen pot (earthen) for 1, 2 3 and 4 weeks. Parameters measured were: external (egg length, egg weight, egg circum-ference, egg shape index, percentage egg weight loss, percentage egg volume loss) and internal (albumen weight, albumen height and egg pH). Storage method had no effect on external egg parameters measured but affected internal parameters (p<0.001). Length of storage had significant effect (p<0.01) on albumen height, and weight and volume percentage losses (internal parameters). Egg weight loss was highest in earthen pot and lowest in both cold and ambient for the first two weeks of storage, thereafter, it increases with length of storage. Egg volume loss was also found to be highest in earthen pot and lowest in cold storage. It can be concluded that room and cold storage can be used for snail egg (Archachatina marginata) between 1-2 weeks of storage for better egg quality.
