Abstract: Changes and change regularity of some minerals in green pepper, green cauliflower, spinach and celery in quick freezing and freezing storage were assayed by using atomic absorption spectroscopy (AAS). The results showed that hot water pre-treatment could induce the loss of Fe, Ca and Zn seriously whereas loss of Fe was higher than Ca and Zn .There were no prominent changes for all of them during freezing storage. It suggested that quick freezing method would be a good way to store vegetables.

Key words: quick freezing vegetabies, minerals, atomic absorption spectroscopy (AAS)
