Abstract

Pickled asparagus (Asparagus officinalis) shoots are characterized with unique flavor and therefore are popular and willingly eaten among consumers. During nine-month refrigerated storage of pickled asparagus the significant increase of the total content of polyphenols and flavonoids as well as increase in antioxidant activity measured against DPPH and ABTS radicals were observed. Extraction with 80% ethanol resulted in above two-fold higher yield of antioxidative substances when compared with the water extraction.
