4275 results about "Carotene" patented technology

The term carotene (also carotin, from the Latin carota, "carrot") is used for many related unsaturated hydrocarbon substances having the formula C₄₀Hₓ, which are synthesized by plants but in general cannot be made by animals (with the exception of some aphids and spider mites which acquired the synthesizing genes from fungi). Carotenes are photosynthetic pigments important for photosynthesis. Carotenes contain no oxygen atoms. They absorb ultraviolet, violet, and blue light and scatter orange or red light, and (in low concentrations) yellow light.

Process for extraction and purification of lutein, zeaxanthin and rare carotenoids from marigold flowers and plants

A process for simultaneously extracting, saponifying, and isolating lutein and zeaxanthin, and a mixture of several rare carotenoids in high purity from plants without the use of harmful organic solvents. Lutein crystals containing 5% zeaxanthin were obtained from the dried petals of Marigold flowers Tagete erecla while zeaxanthin was isolated and purified from the berries of Lycium Chinese Mill (LCM berries). Similarly, this process has been employed to isolate and purify a mixture of lutein, beta-carotene, neoxanthin, violaxanthin, and lutein epoxide from green plants, preferably, kale, collard green, and spinach. These plants, to a lesser extent, also serve as a source of several rare carotenoids such as alpha-cryptoxanthin (Marigolds) and beta-cryptoxanthin (LCM berries). The purified carotenoids isolated by this process are free from impurities and serve as a safe source of nutritional supplement for human consumption as well as providing a suitable and effective color additive for human foods.

Reduced Pigmentation Microalgae Strains and Products Therefrom

The invention provides unique and novel strains of microalgae that have been subjected to non-transgenic methods of mutation sufficient to reduce the coloration of biomass produced by the strains. Biomass produced from such strains can be used in the manufacture of baked goods, gluten free foods, beverages, high lipid algal flours, and other foods. Pigments such as carotenoids and chlorophyll can be undesirable for consumer acceptance when incorporated into foods such as mayonnaise, yogurt, and white sauces that are not traditionally associated with colors such as yellow, red, orange and green. Some pigments, such as chlorophyll, can also create undesirable taste profiles. Use of reduced pigment microalgal biomass expands the range of food products that can be manufactured with healthy lipid profiles. High protein containing biomass of the invention, also reduced in pigmentation, is also incorporated into products such as meat analogues, nutritional bars and meal replacement beverages. The reduced pigmentation microalgae also allow for incorporation of higher amounts of biomass into certain food products that could otherwise be achieved using highly pigmented microalgal biomass. Methods of generating novel reduced pigment microalgae are disclosed herein. The strains provided by the invention are also useful in the manufacture of healthy, neutral colored extracted triglyceride oils.

Edible solvent extraction of carotenoids from microorganisms

A process for extracting carotenoids from a carotenoid-containing starting material produced by microorganisms is described. Said starting material is admixed with edible solvent to effectuate the transfer of carotenoids. Separation of the carotenoid-enriched edible solvent is improved by the formation of a "cake", composed of said carotenoid-containing particulate solids, and, as required, a certain quantity of suitable filtration aid to modify the cake's consistency. Mechanical aids accelerate the separation of the carotenoid-enriched edible solvent. Said mixture may be hydrated to aid the removal of solids and gums from the carotenoid containing edible solvent. The carotenoid-enriched edible solvent is filtered though said cake to reduce the particulate load including any undesirable microbial load. A counter-current process increases the carotenoid concentration of the extract. The carotenoid-enriched edible solvent can be used as an ingredient in human and animal foodstuffs and dietary supplements for the possible prevention and treatment of illnesses and diseases.

Zeaxanthin formulations for human ingestion

Preparations are disclosed containing the 3R-3'R stereoisomer of zeaxanthin as a sole detectable isomer, packaged for oral ingestion by humans as a therapeutic drug or nutritional supplement. Zeaxanthin is a yellow carotenoid pigment found in the macula (in the center of the human retina), which helps protect retinal cells against phototoxic damage. The pure R-R stereoisomer can be prepared by fermenting cells, such as Flavobacterium multivorum (ATCC 55238), which do not create any detectable quantity of the undesired and potentially toxic S-S or S-R isomers, and which do not synthesize any other carotenoids. The R-R isomer can be concentrated, in large quantities and at low cost, into a viscous oily fluid containing about 5 to 20% zeaxanthin, by means of a simple solvent extraction process. This oily fluid can be mixed with a carrier such as vegetable oil and enclosed within a digestible capsule, comparable to a conventional capsule containing Vitamin E. Alternately, a zeaxanthin fluid can be added to various types of foods, such as margarine, dairy products, syrup, cookie dough, and certain types of meat preparations which are not subjected to harsh cooking. Additional purification steps can also be used to purify zeaxanthin to a granular or powdered state which contains nearly pure zeaxanthin. Such processing can be used to create formulations such as ingestible tablets, and particulate formulations that can be added to soups, salads, drinks, or other foods. Preferred stabilizers and anti-oxidants are also disclosed herein. When consumed by humans in any of these modes, the purified R-R stereoisomer of zeaxanthin can help treat and prevent macular degeneration, one of the leading causes of blindness and vision loss, especially among the elderly.
