A method for long-term storage of chlorophyll which is unstable in the surrounding environment, according to an embodiment of the disclosure, includes dissolving a chlorophyll in oil having an unsaturated lipid structure to allow the chlorophyll to be included in the oil. A stabilizer employing oils having long-chain unsaturated lipid structures is used to stabilize chlorophyll.

The present invention relates to the field of upgrading biomass, in particular algal biomass, and more specifically the present invention relates to a method for extracting water-soluble compounds from microalgae and/or cyanobacteria, as well as the product obtained by this method and the uses of same, in particular in the food industry or as food supplements.

Provided herein are compositions and processes for producing compositions from an algae that overproduces protoporphyrin IX (PPIX). Also provided are methods of growing PPIX overproducing algae, methods of isolating PPIX-containing portions from algae cultures and compositions and methods of making food products with PPIX produced by algae. Provided herein are strains and methods to select strains that overproduce PPIX. Also provided are compositions, including edible compositions that include PPIX produced from algae. Specifically, the algal strain over-producing PPIX is an engineered strain of The algal biomass may be used for preparing meat analogues wherein the PPIX compound imparts a meat-like colour and flavour.

Utilizing a sulfated polysaccharide to stabilize a foodstuff containing phycocyanin from Spirulina extract. Compositions and foodstuffs containing phycocyanin from Spirulina extract and a sulfated polysaccharide. The foodstuffs can be syrups, jams, jellies, beverages, confectionary, fruit preparations, condiments and sauces. In particular, the invention uses sulfated polysaccharides from macroalgae such as fucoidan.

A novel alga mutant having improved pigment productivity is provided. The mutant can be used to produce carotenoid-based pigments, particularly, xanthophyll by using a small amount of energy, and thus can effectively produce pigment on an industrial level. In addition, the mutant can be used as a source for foods, health functional foods, and medications which contain a pigment. Further, when account is taken of the physiological characteristics of the euryhaline microalgae Dunaliella and the geological characteristics of Korean, the three sides of which are in contact with the sea, sea-water can be used as a culture medium, with the expectation of reducing the cost and leading to the development of related industries.
