Abstract: A food composition containing viable algae. The food composition includes primarily entrapped living algae cells capable of photosynthetic multiplication which increases the nutritional content of the food composition. Further disclosed is a food composition including primarily fibrous structures containing living algae cells capable of photosynthetic multiplication within the fibrous structures. Further disclosed are methods for producing the compositions, the methods including the steps of: (a) suspending live algae cells in a suitable medium; (b) placing the suspended live algae cells into a setting bath; and (c) incubating to form entrapped living algae cells. In some cases the method further includes the step of bubbling a gas through the setting bath.
