The present invention relates to a novel Schizochytrium sp. strain containing a high protein content, antioxidant pigments and omega-3 fatty acids, and a method for producing a biomass containing a high protein content, antioxidant pigments and omega-3 fatty acids by using the strain. The novel Schizochytrium sp. strain of the present invention simultaneously contains, in the cells thereof, a high content of protein ingredients including amino acids such as glutamic acid, arginine and aspartic acid, antioxidant pigments of beta-carotene and canthaxanthin, and omega-3 unsaturated fatty acid ingredients including eicosapentaenoic acid and docosahexaenoic acid, and thus the strain itself or the biomass and bio-oil produced by culturing and fermenting the strain can be effectively used as a feed composition or a food composition and the like.

Disclosed herein is a plant-based, blood-free diet formulation for hematophagous insects comprising effective amounts of a plant-based protein source and, in some aspects, a carbohydrate source, wherein the plant-based, blood-free diet formulation is suitable for egg production and colony maintenance of hematophagous insects. In some aspects, such hematophagous insects include, but are not limited to, mosquitoes. In some aspects, the plant-based protein source is derived from hemp seeds. In some aspects, the protein source comprises additional proteins in addition to hemp protein. In some aspects, one or more additional proteins in the formulation is derived from spirulina, soybeans, chia seeds, quinoa, oats, nutritional yeast, and / or green peas.

The cascaded extraction of fractional components of an algal biomass includes an initial disruption of an algal cell mass and the centrifugation of the disrupted algal cell mass into each of an oil fraction, an aqueous fraction and a solid fraction. Thereafter, the oil fraction may be purified into an algal oil, while the aqueous fraction may be micro-filtrated and dried into a protein, and the solid fraction may be enzymatically digested, macerated, precipitated and dried into a chitosan.

A photosynthetic microorganism-derived food ingredient composition is provided, wherein the composition has a protein content of at least 40%, wherein the composition has a protein solubility of at least 50%, further wherein the composition has a whiteness index of at least 50. Also provided are methods of adjusting the colour of photosynthetic microorganism biomass, and food ingredient compositions comprising a blend of a proteinaceous photosynthetic microorganism-derived fraction and one or more proteinaceous fractions of dairy, egg, fungi, animal or plant origin.

The present invention relates to a method for processing glycogen present in the biomass of unicellular red algae (URA), particularly those of the genus Galdieria, and to a product obtained in this manner.

The present invention relates to a food composition comprising (a) microalgal biomass material, said biomass material comprising at least 5 wt% of microalgal protein by weight of dry matter of the microalgal biomass, wherein the microalgal biomass material is in the form of non-lysed single cells and / or clusters of non-lysed single cells, with a particle size (D[4,3]) of 2 µm to 100µm, as measured upon redispersion in an aqueous medium at a concentration of 3 wt-% of microalgal biomass material by total weight of the aqueous medium and the microalgal biomass; and (b) a creamer system, comprising a lipid, a carbohydrate carrier; and optionally an emulsifier.

The present invention relates to a method for protein enrichment of a biomass of red unicellular algae such as Galdieria and to the biomass thus obtained.

The present invention relates to a method for preparing native proteins of microorganisms, comprising lysing the microorganisms, separating lipids from the supernatant, filtering the supernatant, and optionally isolating nucleic acids, disinfecting the supernatant, and / or drying the supernatant. The native proteins can be used to prepare protein preparations that are applied in the manufacture of foods or dietary supplements. The present invention also relates to food products or dietary supplements that contain the protein preparations.

The present invention relates to a method for preparing a microbial cell product, said method comprising: providing an aqueous suspension comprising microbial cells; subjecting said suspension to mechanical cell disintegration at a temperature in the range of 15-35° C., preferably at a pH value in the range of 9-11, to obtain an aqueous suspension comprising disintegrated microbial cells; separating the suspension to provide an extract enriched in small cell fragments, and an extract enriched in large cell fragments; and combining at least a portion of each extract, to provide said microbial cell product. The invention further relates to a microbial cell product obtained or obtainable with said method. The invention further relates to the use of said product in foodstuffs, for example as a substitute for egg-white; in animal foodstuffs; and / or in cosmetic formulations.

The invention pertains to non-dairy proteins and nutritional compositions comprising non-dairy protein suitable for infant nutrition and a method of preparing a nutritional composition for infants or young children comprising non-dairy protein.
