Distribution, purification, and delivery of astaxanthin in food system-siftdesk

Abstract

A red-colored carotenoid pigment called astaxanthin possess high antioxidant capability, which is valued in biochemical research. Beside the pharmaceutical and cosmetic industries, it has a potential application in food, especially in foods that are beneficial to human health. Natural astaxanthin is abundantly distributed in food, especially in aquatic products, which is the secret of high-quality aquatic products. While the general extraction of natural astaxanthin has low purity and high cost, it is crucial to search a more economical, efficient and environmental-friendly purification method further. Meanwhile, due to the instability and low biological utilization of astaxanthin, the encapsulation of astaxanthin through delivery system plays a vital role in overcoming the challenges mentioned above and breaking the limitation of astaxanthin in food production and application.

Production and therapeutic use of astaxanthin in the nanotechnology era

“…Notably, AXT delivery systems, such as lipid-based nanocarriers, macro capsulation, nanoparticles, and cyclodextrin inclusion systems, improve AXT bioavailability and antioxidant effect [ 36 , 37 ] (Fig. 4 ).…”

“…Biocompatible and biodegradable nanocarriers must be selected, and preclinical studies must be conducted to evaluate potential toxicity. Finally, regulatory compliance with nanomaterial guidelines and consideration of patent protection for novel encapsulation methods are essential to address regulatory requirements and intellectual property issues (Table 4 ) [ 5 , 14 , 20 , 34 – 37 , 109 – 113 ].…”
