Abstract:
... Moderate electric field (MEF) was evaluated as a pre‐treatment (0–180 V) to carotenoid extraction at four different temperatures (30, 40, 50 and 60 °C) followed by a extraction step using ethanol/water as solvent (75% of ethanol, v/v). During the extraction step, samples were collected at 1, 5, 30, 40 and 50 min. Results showed that MEF allowed higher carotenoid concentration at the beginning of t ...

Abstract:
... Within the past several decades, resource trade‐offs have emerged as the commonly accepted explanation for how carotenoid‐based coloration links to individual performance. However, the literature on carotenoid signalling is inconsistent in how carotenoid resource trade‐offs are defined, assessed and interpreted. We provide a clear statement of the resource trade‐off hypothesis for explaining the h ...
