Abstract :

Fish and its products are the richest sources of vitamin D3. Concerning the lack of information on the concentration of vitamin D3 content of the commercial canned fish products in Iran and incomplete native food composition tables, present study aimed to investigate the frequency distribution of vitamin D3 in the different kinds of canned fish products offered in the Isfahan market. Commercial canned fish from 10 different common brands containing 5 certain types of fish are collected from the market. Samples undergone oil extraction and the extracted oil was diluted to 125 times in methanol and was used for vitamin D3 measurement by RP-HPLC. The limit of detection (LOD) and limit of quantification (LOQ) calculated as 0.05 and 0.04 ├?┬╝g/100 g, respectively. Repeatability and recovery were obtained as 0.18 and 109 respectively. Statistical analysis was performed using Mini Tab program Microsoft Excel. The highest and the lowest concentration of vitamin D3 were measured in canned tuna in vegetable oil (8.51├?┬▒3.55 ├?┬╝g/100 gr) and canned tuna in brine (0.047├?┬▒0.3 ├?┬╝g/100 gr), respectively. The results of this study showed that commercial canned fish, especially the ones which have oily medium are rich sources of vitamin D3. Due to the frequent vitamin D3 deficiency in Iran, declaration of the vitamin D3 content of these products in their attached food composition table can promote its community usage. Especially, for the individuals that suffer from vitamin D3 deficiency, canned fish can be introduced as affordable and suitable food source of this vitamin.
