1629 results about "Astaxanthin" patented technology

Astaxanthin /æstəˈzænθɪn/ is a keto-carotenoid. It belongs to a larger class of chemical compounds known as terpenes (as a tetraterpenoid) built from five carbon precursors, isopentenyl diphosphate, and dimethylallyl diphosphate. Astaxanthin is classified as a xanthophyll (originally derived from a word meaning "yellow leaves" since yellow plant leaf pigments were the first recognized of the xanthophyll family of carotenoids), but currently employed to describe carotenoid compounds that have oxygen-containing components, hydroxyl (-OH) or ketone (C=O), such as zeaxanthin and canthaxanthin. Indeed, astaxanthin is a metabolite of zeaxanthin and/or canthaxanthin, containing both hydroxyl and ketone functional groups.

Schizochytrium limacinum and method or fermenting and producing DHA (Docosahexaenoic Acid) grease utilizing high density of schizochytrium limacinum

The invention belongs to the field of microbial fermentation engineering, and discloses schizochytrium limacinum (Aurantiochytrium sp.SD116). The schizochytrium limacinum is stored in China Microbial Culture Collection Administration Committee General Microbial Center with a number of CGMCC No: 6208), and a method for fermenting and producing DHA (Docosahexaenoic Acid) grease utilizing high density of the schizochytrium limacinum. According to the schizochytrium limacinum and the method disclosed by the invention, a bacterial strain fermenting condition is optimized based on element supply and a fermenting control angle, a carbohydrate supplementation operation is carried out, therefore, high-density fermentation is achieved, dry cell weight finally reaches 70.43g/L, grease content reaches 50.1g/L, DHA occupies more than 35% of total content of fatty acid; moreover, bioactive substances such as beta-carotene, astaxanthin and squalene are contained. The complete set of technology is convenient to operate; higher biomass liveweight and DHA content can be obtained; fermenting cost can be reduced; and the method is suitable for industrial fermenting production.

Functional compound feed special for greenhouse cultivation of litopenaeus vannamei

The invention discloses functional compound feed special for greenhouse cultivation of litopenaeus vannamei. The feed is prepared from import fishmeal, peanut meal, fermented peanut meal, bean pulp, fermented bean pulp, yeast extract, cuttlefish meal, shrimp shell meal, high protein flour, monocalcium phosphate, granulesten, fish oil, a vitaminized mineral mixture premix compound and a functional additive. The functional additive is prepared from vitamins C, bacillus subtilis, seaweed ultrafine smashing micro powder and natural astaxanthin according to proportion. The feed effectively solves the problems of stress, immunity reduction, variety quality losses and the like caused by greenhouse large-scale intensive cultivation of the litopenaeus vannamei and meanwhile has the advantages of being balanced in nutrition, low in cost, green, environmentally-friendly and the like. Main umami substances in muscles of the litopenaeus vannamei fed through the feed are obviously improved, the total amino acid, necessary total essential amino acid and the like are improved in a certain extent, indexes such as the muscle strength, the freshness and the taste are obviously improved, the shrimp body color is close to that of wild shrimps, the immunity of juvenile shrimps and adult shrimps is obviously improved, and the survival rate is high. The feed is suitable for being used in greenhouse high-density large-scale cultivation of the litopenaeus vannamei.

Preparation method of highly-stable and cold water-soluble natural astaxanthin microcapsule preparation

The invention relates to a preparation method of a highly-stable and cold water-soluble natural astaxanthin microcapsule preparation. The method concretely comprises the following steps: uniformly mixing astaxanthin oil, an oil-soluble antioxidant and a water-soluble emulsifier under a heating condition to prepare an oil phase; adding a wall material, a water-soluble antioxidant and a filler to purified water, stirring and dissolving above added materials, and adjusting the pH value of the obtained solution to prepare a water phase; and adding the oil phase to the water phase, uniformly stirring the water phase and the oil phase, grinding the obtained mixture through a sand mill, and carrying out one-step granulation on the obtained emulsion through a cold spraying-starch fluidized bed drying technology to obtain the microcapsule preparation with the particle size of 40-100 meshes. The content reservation rate of the microcapsule preparation disposed at 40DEG C under RH of 75% for 6 months is greater than 95%, and 0.1g of the microcapsule preparation is dissolved in 100ml of water to form a clear, transparent and floating oil-free solution, so the microcapsule preparation can be applied in beverages and other aqueous foods.

High-calcium compound shrimp cake and producing method thereof

The invention relates to a high-calcium compound shrimp cake and a producing method thereof. The high-calcium compound shrimp cake is prepared through carrying out low-temperature chopping and uniform stirring on an all-acete chinensis paste which is prepared through a high-precision waterproof pulverization technology and proportional minced fillet, chicken breast fillet, salt, vital gluten, diced fatty meat, potato starch, monosodium glutamate, disodium 5'-ribonucleotide, sugar, a water retention agent and a quality improver so as to obtain a cake core material, preparing the cake core material into a circular or elliptic shape through a forming machine, wrapping a layer of bread powder on the outside surface of the cake core, and after the shape of the obtained shrimp cake is finalized by quick-freezing, deep-frying the shrimp cake until the appearance of the shrimp cake is golden, so that the shrimp cake is obtained. The shrimp cake prepared by the producing method is golden in appearance, and fresh, tender and slightly crisp in taste, both has the delicate flavors of shrimps, and preserves various beneficial elements such as rich Ca, P, chitin and astaxanthin in shrimp shells, so that the shrimp cake accords with the demands of people on food nutrition, health, taste, and the like.
