Abstract: A method for producing astaxanthin incorporates a method for producing astaxanthin-rich algae cells and a method for extracting astaxanthin therefrom. An initial feedstock comprises healthy algae, water, and nutrients. During a growth phase, carbon dioxide and light from a light source are supplied to the feedstock, thereby amplifying the algae. At least a portion of the nutrients remaining after amplification of the algae are separated from the amplified algae. During a stress phase, carbon dioxide and light are supplied to the amplified algae, thereby promoting production of astaxanthin by the amplified algae. The amplified algae and a cover are placed within an interior of an attrition mill having interior surfaces and media which are substantially non-reactive to astaxanthin and milled to release the astaxanthin from the algae. The cover limits oxidation of the released astaxanthin.

Abstract: Essential oils are extracted from a biomass through milling in a solvent to form a solution of the essential oil in the solvent. The solvent is or is part of a cover than reduces oxidative and other degradation of the essential oil during milling and isolation. The solubilized essential oil may be allowed to adhere to the originating milled biomass to form a feed or nutritional supplement. The solvent may be evaporated from the solubilized essential oil to form an essential oil concentrate. This essential oil concentrate may be used directly, adhered to a different biomass than the originating biomass, or used in combination with pharmaceutical, nutritional, or feed preparations. The essential oil concentrate is preferably adhered to the different biomass through milling under a cover to reduce oxidative and other degradation. The essential oil may be astaxanthin, capsaicin compounds, or cannabinoids.
