CHLOROPHYLL CONTENT AND ANTIOXIDANT ACTIVITY OF SUNFLOWER OIL WITH AROMATIC RAW MATERIALS

Svitlana USATIUK, Liubov PELEKHOVA

Abstract

The article presents the results of the study on chlorophyll content and antioxidant activity (AOA) of sunflower oil with aromatic raw materials. Dried parsley and basil were used as aromatic raw materials. Sunflower oil with aromatic raw materials was obtained by extraction. Dried basil and parsley were in the amount of 2 to 10 %. The chlorophyll content was quantified by the photometric method.   Determination   of   the   AOA   was   carried   out   by   the   Flourescence   Recovery   after Photobleaching  (FRAP)  method.  The  results  show  the dependence  of  chlorophyll  content  on  the amount  of  raw  materials  taken  for  extraction.  The  smallest  content  of  chlorophyll  (26.5  mg/L)  was found in oil with 2 % of dried basil addition. The highest content of chlorophyll (185.4 mg/L) has been found  in  oil  with  10  %  of  dried  parsley  addition.  All  samples  of  the  investigated  oils  have  high antioxidant activity. It increases with the addition of aromatic raw materials from 2 to 10 % by 1.57 times for oils with basil and by 1.48 times for oil with parsley.
