Research advancement and commercialization of microalgae edible oil: a review

Abstract

The global food crisis has led to a great deal of attention being given to microalgal oil as a sustainable natural food source. This article provides an overview of the progress and future directions in promoting the commercialization of microalgal edible oils, including microalgal triglyceride accumulation, suitable edible oil culture strategies for high nutritional value, metabolic engineering, production, and downstream technologies. The integration of the production process, biosafety, and the economic sustainability of microalgal oil production are analyzed for their critical roles in the commercialization of microalgal edible oil to provide a theoretical and scientific basis for the comprehensive development and utilization of microalgal edible oil.

Natural Bioactive Compounds from Macroalgae and Microalgae for the Treatment of Alzheimer’s Disease: A Review

“…Other than environmental impact, regular consumption of fatty fish and fish oil supplements may cause health complications in consumers as some fish species may be contaminated by environmental toxicants including methylmercury, organochlorine pesticides, and polychlorinated biphenyls [ 170 , 171 ]. Moreover, some people may find fish and supplements derived from marine creatures to be unappealing to the taste; they are also not an option for vegetarians and vegans [ 172 ]. In view of this, microalgal oils have been extensively explored in the scientific and industrial domains as a sustainable fish oil substitute with a high concentration of omega-3 fatty acids and excellent productivity [ 169 ].…”

Role of encapsulation on the bioavailability of omega‐3 fatty acids

“…It aligns well with the increasing trend toward eco‐friendly dietary choices (Blanco‐Llamero et al., 2022). Furthermore, controlled cultivation minimizes contamination risks associated with other sources, making it a purer and more reliable source of omega‐3 PUFA (Ryckebosch et al., 2014; Sprague et al., 2017; Xue et al., 2021).…”

“…Plant FAs have been used in many fields, including the food, chemical, and energy industries [ 3 , 4 ]. FAs also constitute an important energy source for humans, and edible FAs are mainly derived from plants [ 5 ]. The main difference between edible and industrial oils is in their composition; if the palmitic acid and stearic acid content of plant oil is too high, then it will be considered unsuitable as edible oil.…”
