The Extraction of β-Carotene from Microalgae for Testing Their Health Benefits

Abstract: β-carotene, a member of the carotenoid family, is a provitamin A, and can be converted into vitamin A (retinol), which plays essential roles in the regulation of physiological functions in animal bodies. Microalgae synthesize a variety of carotenoids including β-carotene and are a rich source of natural β-carotene. This has attracted the attention of researchers in academia and the biotech industry. Methods to enrich or purify β-carotene from microalgae have been investigated, and experiments to understand the… Show more

“…However, in recent years, the search for more sustainable foods has focused the attention on the use of alternative sources to obtain bioactive compounds. Among these natural alternatives, the use of microalgae seems to be a suitable source from which to obtain these bioactive compounds due to the fast growth, high yield, and short cultivation time of microalgae [ 20 ] ( Figure 1 ). In addition, residues from the agrifood industry are promising sources of these compounds with biological activity.…”

“…Β-carotene is particularly abundant in Dunaliella salina which is considered to be the largest producer of this carotenoid (up to 13% of its biomass), but it is produced also in Chlorella sorokiniana , Nannochloropsis gaditana , among others [ 126 ]. Lutein is a xanthophyll member of the carotenoid family and occurs in both animal as well as plant products like in egg yolk, spinach, corn, and kale [ 131 ].…”

“…[1] Moreover, these organisms present some advantages compared with higher plants, such as DOI: 10.1002/mnfr.202200492 faster growth, higher yield, and shorter cultivation time, which make them an interesting source of bioactive compounds such as astaxanthin, fucoxanthin, 𝛽-carotene, omega-3 fatty acids, and polyphenols. [2][3][4][5][6] Among them, Dunaliella salina is one of the best sources of natural 𝛽-carotene, up to 14% of its total dry weight, [7] presenting the 50% of total 𝛽-carotene as a 9-cis isomer. Previous studies have reported that the administration of this 𝛽-carotene isomer presented a higher tissue accumulation, antioxidant, and biological effects than (all-E)-𝛽-carotene.…”
