Description:
The present project was aimed at determining the content, quality, and purity of β-carotene
extracted from Azolla filiculoides in the Anzali Wetland, comparing it with synthetic β-
carotene, and measuring its economic value. One treatment had β-carotene derived from
Azolla filiculoides in the Anzali Wetland through the alkaline hydrolysis method in the
summer of 2014. Treatments were kept at 4 °C for one year. Synthetic β-carotene was used as
the control. The quality of the treatments was assessed by applying some chemical tests,
including the measurement of the content and quality of β-carotene, colorimetry using the
Hunter-LAB method, determination of the purity and vitamin A employing high-performance
liquid chromatography (HPLC), estimation of the dwell-time duration at 5 °C, and
measurement of the solubility of β-carotene in water. The results of the tests regarding the
purity, concentration, colorimetry, vitamin compounds, dwell time, and solubility in the
experimental β-carotene, compared with those in the control, revealed no significant
difference (p〉0.05). Moreover, the factors showed no significant difference between the
control and experimental treatments during the dwell time (p〉0.05). The natural β-carotene
had a good quality during the storage period at 5 °C for one year. Since there was no
significant difference between the β-carotene derived from Azolla filiculoides and the
synthetic one in terms of the chemical tests, purity, and dwell time, and since the natural β-
carotene derived from Azolla filiculoides takes precedence over the synthetic one in terms of
the economic value, it is recommended that natural β-carotene extracted from Azolla
filiculoides be substituted for synthetic β-carotene in the food industry.
