Nutritional evaluation of microalgae oils rich in omega-3 long chain polyunsaturated fatty acids as an alternative for fish oil.
Eline Ryckebosch,Charlotte Bruneel,Romina Termote-Verhalle,Koen Goiris,Koenraad Muylaert,Imogen Foubert +5 more
TL;DR: It was shown that microalgae oils from Isochrysis, Nannochloropsis, Phaeodactylum, Pavlova and Thalassiosira contain sufficient omega-3 LC-PUFA to serve as an alternative for fish oil, which was used as the 'golden standard'.

Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
TL;DR: In this paper, the use of Folin-Ciocalteu reagent rather than the FolinDenis reagent, gallic acid as a reference standard, and a more reproducible time-temperature color development period was investigated.
