The endosymbiotic jellyfish Cassiopea andromeda represents a yet untapped marine species that could be targeted as a new source for bioproducts, including food and feed. Also, the potential use of contained valuable ingredients, such as carotenoids and other antioxidants, under controlled aquaculture conditions might be a particularly promising pathway. However, this requires close knowledge about physiology and culture condit...

Caulerpa lentillifera, known as `sea grapes´ or `green caviar´, is increasingly in demand as a sea vegetable for human consumption. The seaweed is cultivated in ponds in the Khánh Hòa province in Van Phong Bay, Viet Nam, during the dry season (March-October). The harvested sea grape fronds are graded into different qualities based on their physical characteristics for retail on the local market or for export. Based on systemat...

Seaweeds are a major contributor to global marine aquaculture production, with the biomass being mainly used, among others, for human nutrition, pharmaceutics, and cosmetics. However, green seaweeds are severely underrepresented, compared to red and brown macroalgae. Caulerpa lentillifera (known as “sea grapes” or “green caviar”) is an edible, green seaweed with a distinctive texture and various nutritional benefits. In this r...

Introduction The up-side down jellyfish Cassiopea andromeda represents a yet untapped marine species that could be targeted as a new source for functional ingredients, such as natural pigments and antioxidants. Since C. andromeda hosts endosymbiotic dinoflagellates, this jellyfish contains peridinin pigments, which are linked with high antioxidant capacities and many other health-promoting properties. This study investigates t...

The interest in edible sea grapes ( Caulerpa lentillifera ) is increasing due to their potentially beneficial effect on human health. This macroalga, already used for direct and indirect human consumption, is grown in aquacultures in Vietnam and The Philippines. Here, the edible fronds of sea grapes were examined for their antioxidant activity (AOA) at light intensities from 140 to 300 µmol photons m −2 s −1 and compared to co...

The green macroalga Caulerpa lentillifera (sea grapes, green caviar) is a promising source for future nutrition due to its beneficial composition for human consumption. It is cultured in tidal ponds, mainly in Vietnam and the Philippines, and stored for shipment and retail in plastic containers, like polystyrene (PS) and polyethylene terephthalate (PET), exhibiting different properties. This study investigates the influence of...
