Use of sinapic acid alkyl esters as antioxidants in microencapsulated flaxseed oilArslan, Derya (Avtor) Tontul, İsmail (Avtor) Polak, Tomaž (Avtor) Poklar Ulrih, Nataša (Avtor) sinapic acidalkyl estershexyl sinapatemicroencapsulated faxseed oilantioxidant efectEnzymatically synthesized hexyl (C6) and palmitoyl (C16) esters of sinapic acid were incorporated into microencapsulated faxseed oil as antioxidants. The antioxidant activity and lipid oxidation retarding efect of the sinapic acid esters were tested during storage using diferent methods. Sinapate-enriched microencapsulated faxseed oils were found to be more stable against oxidation during storage compared to microencapsulated and free oil. In addition, the results of antioxidant analyses and lipid oxidation measurements revealed the superiority of palmitoyl sinapate (longer alkyl side chain) over hexyl sinapate. The polarity of the analysis medium provides information on the antioxidant properties and stability of the added sinapic acid esters since sinapic acid alkyl esters gave diferent results when tested directly in the analysis medium. The results showed that lipophilic esters of sinapic acid, especially palmitoyl sinapate, can be successfully used as antioxidants to stabilize microencapsulated faxseed oil.20252026-04-10 16:26:29Članek v reviji181664UDK: 577.1:664.33:613.2ISSN pri članku: 1935-5130DOI: 10.1007/s11947-024-03469-yCOBISS_ID: 199087363sl
