The invention discloses a preparation method of high-absorptivity silica as lutein carrier. The method includes adding sodium silicate into a synthesis kettle, introducing steam for heating while stirring, adding water, stirring for reaction to obtain a reaction substrate A, and adding sulfuric acid to the reaction substrate A to obtain reaction solution B; simultaneously adding sulfuric acid and sodium silicate into the reaction solution B, performing synthesis reaction for a given period of time, stopping feeding of sodium silicate, adding sulfuric acid only for post-acidification, and aging to obtain dilute slurry D; and filtering the dilute slurry D, washing, slurrying, drying and packaging to obtain silica microspheres as lutein carrier. The invention accurately controls each process so that the prepared high-absorptivity silica as lutein carrier has high adsorption and good dispersibility and flowability after adsorbing lutein.

This invention relates to the use of the combination of 25-hydroxyvitamin D3 (“25-OH D3”) and antioxidants/anti-inflammatories (ascorbic acid vitamin E and canthaxanthin) to make a premix or feed which can ameliorate various problems observed in poultry which have been subject to overfeeding. Feeds containing the 25-OH D3 and antioxidants/anti-inflammatories and premixes are also provided.

Disclosed is a pet chew product, comprising a tubular basic strip, wherein the tubular basic strip is internally provided with an axial channel with a polygonal cross section, and when the axial channel is squeezed, an upper wall of the axial channel protrudes downwards and is fitted with a corresponding engagement position on a lower wall thereof.

The invention pertains to a method for synthesizing a product of interest by culturing a microalgal cell obtained from a subterranean habitat for producing the product of interest. The microalgal cell obtained from a subterranean habitat can be cultured in the dark, in light, in low nutrition, or nutrient rich conditions for at least a portion of production cycle. A combination of these conditions can be used to specifically manipulate a microalgal cell culture to produce a product of interest. The product of interest can be a water-soluble carotenoid, for example, a water-soluble carotenoid produced by culturing an algae belonging to the genus Haematococcus or a capsular exopolysaccharide produced by culturing an algae belonging to the genus Parachlorella. Compositions containing the water-soluble carotenoid, for example, as sunscreen and compositions containing the exopolysaccharide, for example, as moisturizing cream are also described.
