The present invention relates to a method for extracting an oil rich in polyunsaturated fatty acids (PUFA), in particular an oil of microorganisms rich in docosahexaenoic acid (DHA, C22:6n3), in particular oils comprising more than 60% of PUFA relative to the total mass of fat.

A type I collagen or elastin production promoter containing a mycosporine-like amino acid or a salt thereof as an active ingredient; and a method for promoting type I collagen or elastin production, the method including administering an effective amount of a mycosporine-like amino acid or a salt thereof.

An object of the present invention is to preserve the total content of chlorophyll in an extract while increasing the extraction yield of a Spirulina extract. Another object of the present invention is to provide a pharmaceutical composition and health functional food for prevention or treatment of degenerative cranial nerve diseases containing a Spirulina extract as an active ingredient, and to provide a method for treating degenerative cranial nerve diseases using a Spirulina extract. The present invention provides a method for producing a Spirulina extract including the steps of (a) preparing a Spirulina powder; (b) adding 50% to 80% of ethanol to the Spirulina powder and performing an ultrasonic pretreatment at 15° C. to 35° C.; (c) extracting a Spirulina extract at 50° C. to 80° C.; (d) vacuum-concentrating the Spirulina extract; and (e) freeze-drying the vacuum-concentrated Spirulina extract.

The present invention is related to extracts rich in polar lipids obtained or obtainable from macroalgae, microalgae, photosynthetic bacteria and/or photosynthetic organ(s) and/or tissue(s) of a plant and combinations thereof as well as their uses as emulsifiers.

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.

Disclosed herein are pigment compositions for meat substitutes and meat substitutes including such pigment compositions. The pigment compositions include Phycoerythrin. In an aspect, the pigment compositions include red algae or a red algae extract. In an aspect, the pigment compositions provide a pink and/or red color to raw meat substitutes that transitions to a brown color or to colorless after cooking.
