| Summary: | Encapsulation of sinigrin in liposomes with the proliposomal method was performed in order to evaluate the effect of this process on in vitro simulated digestion and antioxidant potential of sinigrin. The recovery of sinigrin after simulated gastric and duodenal digestion of its free and liposomal forms was determined with HPLC-UV using human digestive juices. The antioxidant potential of sinigrin and sinigrin-loaded liposomes was determined with the Rancimat test as their ability to prolong oxidative stability of edible oil. The efficiency of 62% was obtained by encapsulating sinigrin in liposomes. The values of mean diameter, polydispersity index and zeta potential showed satisfactory size uniformity and physical stability of the liposomes containing sinigrin. Liposomes were shown to inhibit the digestion of sinigrin in both human gastric and intestinal juices, clearly enabling its prolonged release. Moreover, sinigrin in the liposomal form significantly prolonged the induction time of edible oil oxidation compared to its free form. The results obtained are encouraging from the point of view of a possible incorporation of the sinigrin-loaded liposomes in real functional food systems or their use as nutraceuticals. |
