The present disclosure relates to novel sialidase enzymes having a preference for cleaving N-glycolylneuraminic acid (Neu5Gc) from glycoconjugates over cleaving N-acetyineuraminic acid (Neu5Ac). The present disclosure further provides the polypeptide of such novel sialidase and its catalytic pockets; the recombinant host cells expressing the same, as well as the enzymatic, pharmaceutical, and consumable compositions comprising such novel sialidases. Probiotic compositions comprising a bacterium that expresses the sialidase having a preference for Neu5Gc over Neu5Ac, and methods for removing Neu5Gc from consumable products are also provided. Also disclosed are methods for treating or preventing various diseases, disorders, and inflammatory conditions in a subject using the novel sialidases.

A method of cleaning mother's milk, involving ex vivo contacting mother's milk having an initial concentration of an antidepressant therein with a solid substrate (preferably a porous substrate) adapted to remove the antidepressant from the milk to produce a cleansed milk product having a reduced concentration of the antidepressant.

The present invention relates to a structure composed of -cyclodextrin, a linker and a supporter, and a preparation method thereof. The cellulose-adipate--cyclodextrin structure of the present invention is effective in removing cholesterol from foods, and the use of the cellulose-adipate--cyclodextrin structure may reduce the onset of adult and chronic diseases due to excessive intake of cholesterol, thereby contributing to maintenance, recovery and promotion of health.

The invention relates to a process for dephosphorylation of skim milk, ultra-filtered milk (UF milk) or micellar casein isolate (MCI) comprising (i) acidification of a skim milk, UF milk or MCI preferably not lower than pH 6.0, preferably between 6.0 and 6.7, (ii) cooling the acidified skim milk, UF milk or MCI to the temperature between 0 C. and 15 C., (iii) adding gluconate and/or maleate to the cooled skim milk, UF milk or MCI and, (iv) washing the skim milk, UF milk or MCI, to remove phosphorus, thus dephosphorylating the skim milk, UF milk or MCI, preferably to an extent that the total phosphorous content of the skim milk, UF milk or MCI is reduced with at least 20%, preferably 20-40%, more preferably 30-40% compared to the material provided to step (i). The invention also relates to dephosphorylated MPC, MPI or MCI obtainable by the process of the invention, and to a liquid heat-sterilized enteral nutritional composition comprising 2.0-3.0 kcal/ml wherein 16-35 en % is provided by protein, the combination of caloric content and relative protein caloric content selected such that there is 10-18 g/100 ml protein, preferably 12-18 g/100 ml protein in the composition, wherein the protein comprises micellar casein (MC), whey protein (WP) and optionally caseinate (CAS), wherein there is at least 70 wt % MC and less than 15 wt % WP, based on total protein content, and wherein the composition has a total amount of phosphorous less than 192 mg/100 ml and/or 30-80 mg/100 kcal, preferably at least 30-80 mg/100 kcal, most preferably less than 192 mg/100 ml and 30-80 mg/100 kcal.
