The search for new sources of functional molecules remains an
important goal in the food industry. To cope with the high cost of
animal proteins for a long time, researchers and industry have used
plant proteins such as soy or wheat. However, proteins extracted
from microalgae are a good alternative combining both a remarkable
nutritional value, a good availability, but also, as it was
demonstrated in this study, good functional properties. Therefore,
A. platensis protein isolates could in future be used as ingredients
for the formulation of food products in the form of emulsions,
foams or gels if their functional properties are characterized
according to various physicochemical conditions. In addition, the
ability of these proteins to form films could allow development
of edible coatings with new features.
