“…The freeze-dried biomass of E. huxleyi (EHUX) and C. pseudoroscoffensis (CP) used in the production of starch-based films was characterised by elemental analysis and protein estimation (Supplementary Table S1). The protein content (16.1 ± 0.1% for EHUX and 11.2 ± 0.1% for CP) was similar to those previously obtained from other batches produced under the same conditions [22,23], suggesting a consistent composition between different cultures. The microalgae under study were also observed by scanning electron microscopy (SEM).…”

“…A previous study with cultured E. huxleyi biomass revealed 50.8% ash, 20.3% lipids, 15.3% proteins, and 3.7% sugars [22]. Using the same methodologies for characterisation of other coccolithophore species, Chrysotila pseudoroscoffensis (originally named as Pleurochrysis pseudoroscoffensis) showed 45.5% ash, 11.6% proteins, 11.0% carbohydrates, and 6.4% lipids [23].…”

“…The strain of E. huxleyi (AC453) was obtained from Roscoff Culture Collection (RCC1250), while the strain of C. pseudoroscoffensis (ES-PL0118-01) was provided by Instituto de Ciencias Marinas de Andalucía (ICMAN). Both microalgae were cultured under conditions previously described [22,23], as presented below. For both cultures, growth was monitored every day by optical density (750 nm) and microscopic observations.…”

“…Coccolithophore microalgae (classified in phylum Haptophyta and class Coccolithophyceae) have in their composition both bioactive compounds (such as lipids [22,23] and pigments [24]) and CaCO 3 plates that can be explored to produce sustainable active packaging. As a characteristic of this class, the CaCO 3 plates, known as coccoliths, form an external covering of the cell surface, a coccosphere.…”

Coccolithophore microalgae, such as Emiliania huxleyi (EHUX) and Chrysotila pseudoroscoffensis (CP), are composed of calcium carbonate (CaCO3) and contain bioactive compounds that can be explored to produce sustainable food packaging. In this study, for the first time, these microalgae were incorporated as fillers in starch-based films, envisioning the development of biodegradable and bioactive materials for food packaging applications. The films were obtained by solvent casting using different proportions of the filler (2.5, 5, 10, and 20%, w/w). For comparison, commercial CaCO3, used as filler in the plastic industry, was also tested. The incorporation of CaCO3 and microalgae (EHUX or CP) made the films significantly less rigid, decreasing Young’s modulus up to 4.7-fold. Moreover, the incorporation of microalgae hydrophobic compounds as lipids turned the surface hydrophobic (water contact angles > 90°). Contrary to what was observed with commercial CaCO3, the films prepared with microalgae exhibited antioxidant activity, increasing from 0.9% (control) up to 60.4% (EHUX 20%) of ABTS radical inhibition. Overall, the introduction of microalgae biomass improved hydrophobicity and antioxidant capacity of starch-based films. These findings should be considered for further research using coccolithophores to produce active and sustainable food packaging material.

“…Therefore, microalgae are becoming increasingly popular as a source of high-value compounds with interesting bioactivity and chemical diversity. That said, the knowledge and understanding around their PLs' characteristics remains largely limited [164]. Algae contain lipids such as n-3 PUFAs with antioxidant potential [161,165], which are sometimes attributed to the presence of glycolipids that are also known to exhibit antitumor and anti-inflammatory properties [166,167].…”

Cardiovascular diseases (CVD) remain the leading cause of death across the globe, hence, establishing strategies to counteract CVD are imperative to reduce mortality and the burden on health systems. Dietary modification is an effective primary prevention strategy against CVD. Research regarding dietary supplementation has become increasingly popular. This review focuses on the current in vivo, in vitro, and epidemiological studies associated with that of omega-3 polyunsaturated fatty acids (n-3 PUFAs) and polar lipids (PLs) and how they play a role against CVD. Furthermore, this review focuses on the results of several major clinical trials examining n-3 PUFAs regarding both primary and secondary prevention of CVD. Notably, we place a lens on the REDUCE-IT and STRENGTH trials. Finally, supplementation of PLs has recently been suggested as a potential alternative avenue for the reduction of CVD incidence versus neutral forms of n-3 PUFAs. However, the clinical evidence for this argument is currently rather limited. Therefore, we draw on the current literature to suggest future clinical trials for PL supplementation. We conclude that despite conflicting evidence, future human trials must be completed to confirm whether PL supplementation may be more effective than n-3 PUFA supplementation to reduce cardiovascular risk.
