The present invention discloses a native rapeseed protein isolate comprising 40 to 65% cruciferins and 35 to 60% napins and having a solubility of at least 88% when measured over a pH range from 3 to 10 at a temperature of 23±2° C.; wherein the native rapeseed protein isolate comprises from 5% to 65% on dry matter of 12S rapeseed protein where the presence of 12S is verified by Blue Native PAGE.

Described herein are controlled release pet food compositions comprising: a matrix comprising: a fiber component comprising a high solubility fiber source and low solubility fiber source, and a polyphenol source; wherein the matrix is adapted to deliver the polyphenol source to the lower gastrointestinal (GI) tract of a mammal after ingestion by the mammal. Methods of making and using these compositions are also described.

A composition contains quercetagetin and 6-hydroxykaempferol, and, optionally further includes patuletin. The composition has an excellent antioxidant effect, and can be used as an active additive in food, drugs, health care products, cosmetics, and feed. In addition, the composition can prompt animal growth, reduce ratio of feed to gain, and improve meat quality in the feed.

Provided are pet food grains for reducing regurgitation after a meal, containing: puffed grains having a moisture content of 3% to 12% by mass, in which a proportion of grains, each of which has a surface with an arithmetic average surface roughness Sa of 14 μm or greater which is measured using an L-filter having a nesting index of 0.25 mm, is 60% or greater, and a proportion of grains whose hardness immediately after being immersed in dilute hydrochloric acid (pH of 2.5) at 25° C. for 10 minutes is 2.5 kgw or less is 60% or greater.

A stable carotenoid microcapsule having high bioavailability and a preparation method therefor. The method includes the following steps: a) mixing carotenoid crystals with an organic solvent, and dissolving the mixture to obtain a carotenoid solution; b) introducing the carotenoid solution and a grease into a dispersion system to fully disperse carotenoid into the grease, and vaporizing the organic solvent to obtain a carotenoid-containing dispersion liquid; c) mixing the carotenoid-containing dispersion liquid and a protective colloid aqueous solution, and emulsifying the mixture to obtain an emulsion; and d) performing spray granulation and drying to obtain a carotenoid microcapsule.
