Abstract:

The freeze-dried cooked beef slices were dipped in water to observe the rehydration characteristics, such as shape, color and microstructure. The results showed that the shape, color and microstructure of products are not significantly affected by freeze-drying. GC-MS analysis indicated that the sorts and contents of flavor compounds do not significantly changed. The sensory analysis revealed that the rehydrated products has very similar flavor to the fresh ones.

Key words: cooked beef slice, freeze-drying, rehydration quality
