“…Furthermore, it is also estimated that by 2025, the microalgae product’s market will become a large-scale business [ 107 ]. For the main microalgae-derived pigments, a worldwide commercial production of around 10,000 tons/year for Spirulina , 4000 tons/year for Chlorella , 1000 tons/year for Dunaliella , and 200 tons/year for Haematococcus is estimated [ 108 ]. Face to these results, it is possible to foresee, in the next years, an increase use of algae pigments in different industrial fields.…”

Microalgae productive chains are gaining importance as sustainable alternatives to obtain natural pigments. This work presents a review on the most promising pigments and microalgal sources by gathering trends from a 10-year bibliometric survey, a patents search, and an industrial and market analysis built from available market reports, projects and companies’ webpages. The performed analysis pointed out chlorophylls, phycocyanin, astaxanthin, and β-carotene as the most relevant pigments, and Chlorella vulgaris, Spirulina platensis, Haematococcus pluvialis, and Dunaliella salina, respectively, as the most studied sources. Haematococcus is referred in the highest number of patents, corroborating a high technological interest in this microalga. The biorefinery concept, investment in projects and companies related to microalgae cultivation and/or pigment extraction is increasingly growing, particularly, for phycocyanin from Spirulina platensis. These pieces of evidence are a step forward to consolidate the microalgal pigments market, which is expected to grow in the coming years, increasing the prospects of replacing synthetic pigments by natural counterparts.

“…The microalgal lipids can be divided into two major groups: (i) the neutral lipids (non-polar lipids) such as sterol, triacylglycerol (TAG), and free fatty acids are storage lipids and used as a stock of energy, and (ii) the polar lipids are structural lipid usually found in cell membranes. Short-chain saturated fatty acids (mainly neutral lipids) are valorized in the biofuel industry while, thanks to their health benefits, long-chain polyunsaturated fatty acids (esterified with glycerol in microalgae and generating TAG or polar lipids) are used in the nutraceutical industry or in active drug processing [ 164 , 165 ].…”

N-3 polyunsaturated fatty acids (n-3 PUFAs), and especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential compounds for human health. They have been proven to act positively on a panel of diseases and have interesting anti-oxidative, anti-inflammatory or anti-cancer properties. For these reasons, they are receiving more and more attention in recent years, especially future food or feed development. EPA and DHA come mainly from marine sources like fish or seaweed. Unfortunately, due to global warming, these compounds are becoming scarce for humans because of overfishing and stock reduction. Although increasing in recent years, aquaculture appears insufficient to meet the increasing requirements of these healthy molecules for humans. One alternative resides in the cultivation of microalgae, the initial producers of EPA and DHA. They are also rich in biochemicals with interesting properties. After defining macro and microalgae, this review synthesizes the current knowledge on n-3 PUFAs regarding health benefits and the challenges surrounding their supply within the environmental context. Microalgae n-3 PUFA production is examined and its synthesis pathways are discussed. Finally, the use of EPA and DHA in food and feed is investigated. This work aims to define better the issues surrounding n-3 PUFA production and supply and the potential of microalgae as a sustainable source of compounds to enhance the food and feed of the future.

Microalgae have garnered significant interest among researchers and industries as a potential source of valuable products that can find applications in the food, feed, biofuels, cosmetics, pharmaceuticals, and nutraceuticals industries. Microalgae can remediate various waste streams. This review discusses the current trends in the valorization of algal biomass and proposes integrated biorefinery approaches to produce high‐value products by sustainable routes. In such processes, the waste streams can be used as a source of nutrients for the production of microalgal biomass, rich in high‐quality lipids, digestible proteins and bioactive compounds. The integrated approaches presented in this study offer cost‐effective and environment‐friendly processing techniques while expanding the bioproducts portfolio in the food and therapeutics sector. The simultaneous or sequential extraction of valuable compounds from microalgae makes the biorefinery proposition appealing for waste minimization, revenue diversification, and complete feedstock utilization. The systematic exploration of microalgae on a large scale is required to evaluate its future as a favorable resource for biorefinery products. This would also necessitate detailed techno‐economic, environmental, and lifecycle assessment for the biorefinery processes. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
