An algal biomass and supernatant derived from at least one species of algae exhibits the ability to maintain general health in humans and non-human animals and promote a healthy immune system in them. Food, feed and nutritional supplements comprising an algal biomass or supernatant derived from at least one species of algae are described. Methods of maintaining general health or promoting a healthy immune system in humans and non-human animals comprises administering to the animal in need thereof an algal biomass or supernatant derived from at least one species of algae, or an extract, derivative or homeopathic compound derived from the algae species, biomass or supernatant, or a composition thereof.

A process for providing phycocyanin from a blue-green algae biomass comprising the steps of forming a slurry of blue-green algae by mechanically mixing the blue-green algae in water to break up filaments of the biomass and incubating the macerated slurry in a container with at least a 1% flocculating agent for a period of time sufficient to separate a blue extract from the slurry. The blue extract is separated and filtered through a filter to obtain a blue filtrate and the blue filtrate is mixed in a container with an ammonium sulfate precipitate for a suitable period of time to obtain supernatant protein separation. The supernatant is syphoned from the container and the settled participate is centrifuged at a rpm ranging from about 3500 rpm to about 4500 rpm for a sufficient time to produce phycocyanin precipitate. The phycocyanin precipitate is spray dried to form a phycocyanin powder which is collected and purified with a citrate and water mixture to obtain a supernatant and phycocyanin residue with the phycocyanin residue being redissolved in water and sprayed to dry into a phycocyanin powder.

A rice milk according to an embodiment of the present invention includes a mixture of rice protein powder and rice enzyme digestion extract concentrate in purified water. The rice milk using rice protein is suitable for allergy-sensitive elderly and infants to drink and also provides functionality to stressed adults because it has milk properties, high nutritional value and good digestion by mixing rice enzyme decomposition extract obtained by digesting rice starch and rice protein with subsidiary ingredients. In addition a method for preparing a rice milk using rice protein according to an embodiment of the present invention includes a first enzymatic digestion step, a second enzymatic digestion step, a filtration step, a rice protein powdering step, and a rice enzyme extract saccharification solution concentration step.
