The value of bleached and unbleached petioles of celery for pickling in vinegar, tomato, and horseradish pickles was compared. The bleaching of petioles did not affect the results of phytometric measurements and only slightly affected the chemical composition of the petioles. The pickling brought about changes in the chemical composition of celery, no effect of the type of pickle and petiole on the level of the investigated factors in the final product being assessed. The pickle increased the content of dry matter, ash, and acids in the raw material, while vitamin C, chlorophylls, and nitrates were diluted. During the storage of preserves the level of nitrites increased. Pickled celery was characterized by high organoleptic quality. The preserves in vinegar and tomato pickles obtained a particularly high scoring.
