Preparation method and application of astaxanthin H1-, or H2- or J-aggregate water dispersion system are provided. The three kind of color-different astaxanthin multimer nano-dispersion systems utilize a special molecular structure of natural biomacromolecule chitosan and fish sperm DNA as well as physical interaction between macromolecules to induce formation and stability of astaxanthin multimers under solvent and salt ion-effects. Low-toxicity ethanol is selected as a good solvent for astaxanthin. The organic solvent can be completely removed in the later stage of the preparation process, and can be further enriched and recycled, which is beneficial to clean production and low cost. By adjusting process parameters, the H1-, or H2- or J-type astaxanthin aggregate water dispersion system can be obtained, so as to control a coloration range of astaxanthin water-based products to be yellow, orange and pink. Furthermore, during concentration, dehydration and reconstitution, astaxanthin aggregation patterns and coloring effects are maintained.

The present invention relates to a method including heat treatment of a composition including chitin and water-soluble vitamins and/or derivatives thereof. The invention also relates to a granule which can be obtained by the method according to the invention, a granule comprising chitin and water-soluble vitamins and/or derivatives thereof, and the use of said granules in human food or animal feed, more particularly in fish feed. Finally, the invention relates to the use of chitin to protect water-soluble vitamins during heat treatment.

The present application discloses a composition of a butyrate or a derivative thereof and benzoic acid, preparation method and use as a feedstuff additive thereof, wherein the composition comprises 5 wt % to 50 wt % of the butyrate or the derivative of butyric acid, and 50 wt % to 95 wt % of the benzoic acid or benzoate. The benzoate and butyrate dissociate into acidic molecules when they enter into animals' bodies. The butyric acid stimulates parietal cells to grown and the parietal cells produce hydrochloric acid, which thereby reduces the pH value in the stomach. Benzoic acid can inhibit facultative anaerobes such as Lactobacillus and butyric acid-producing anaerobic bacteria in the stomach, rendering the two floras become predominant microflora, and therefore produce more endogenous organic acids such as lactic acid and butyric acid. These acids are beneficial to gastrointestinal health and animal growth. As a result, a synergy effect of the two components in the composition is achieved.

Subject of the invention is a composition for oral administration comprising a beverage and beads distributed in the beverage, wherein the beads have an average diameter between 2 to 10 mm, comprise more than 50% (w/w) dietary fibres, and wherein the amount of beads in the composition is between 1 and 20 wt. %. The invention also relates to devices and uses of the composition for reducing the weight of an individual and/or preventing weight gain.
