The present invention relates to a composition for improving bone health, including a functional fermented material using oysters, and the composition includes a fermented extract extracted from a fermented material of oysters and seaweed, which is obtained by fermenting oysters and seaweed, and the fermented extract may promote bone formation by suppressing the activity of osteoclasts and promoting the activity of osteoblasts.

According to the present invention, it is possible to provide a composition for improving bone health, containing large amounts of taurine and vitamins and containing natural gamma-aminobutyric acid (GABA) and seaweed oligosaccharides from seaweeds using oysters.

Further, it is possible to provide a composition for improving bone health, including a functional fermented material using oysters which is excellent in effects of preventing and suppressing the occurrence of osteoporosis.

The present invention discloses a method for the preparation of skipjack tuna extract having hypouricemic effect and the use thereof, which is simple in processing operations, low in production cost, and is free from pollution. The prepared skipjack tuna extract has a potent hypouricemic effect, and has a significant therapeutic effect on hyperuricemia, with no toxic and side effects. The method in an example of the present invention comprises: pretreating skipjack tuna to obtain a skipjack tuna slurry; enzymolysing the skipjack tuna slurry to obtain a crude enzymolysis liquid; removing fishy smell and bitter taste, removing impurities by activated charcoal, and filtering to obtain a refinded enzymolysis liquid; concentrating under vacuum and spray-drying to obtain the skipjack tuna extract. The present invention further discloses use of the skipjack tuna extract in health care products or food products.

An object of the present invention is to remove or reduce iodine contained in a marine natural product extract, while maintaining the original flavor, taste, appearance, etc. of the marine natural product extract before processing. A first anion exchange membrane (5) and a second anion exchange membrane (6) are sequentially arranged from the anode (3) side. Between the anion exchange membranes (5, 6), an extract receiving compartment (9) is formed and fed with a marine natural product extract (21). An iodine recovery compartment (8) is formed on the anode side of the first anion exchange membrane (5). A replenisher receiving compartment (10) is formed on the cathode side of the second anion exchange membrane (6) and fed with a replenisher containing chlorine ions (24). During electrodialysis, the iodine ions contained in the marine natural product extract (21) pass through the first anion exchange membrane (5) and migrate into the iodine recovery compartment (8), while the chlorine ions contained in the replenisher (24) pass through the second anion exchange membrane (6) and replenish the extract receiving compartment (9).

Provided herein is a method of reducing postprandial concentrations of glucose in a subject's blood comprising administering to the subject, prior to or during a meal, an effective amount of a combination of a marine peptide and a fish nucleotide, sufficient to reduce the glucose concentration in the subject's blood. Further provided herein is a method of reducing postprandial concentration of ghrelin in a subject's blood, comprising administering to the subject, prior to or during a meal, an effective amount of a combination of a marine peptide and a fish nucleotide sufficient to increase the blood component wherein the combination is administered to the subject.

A product for cooking a food in oil and/or fat is provided. An adjusted pH protein suspension is produced in an aqueous or dry form and includes myofibrillar proteins and sarcoplasmic proteins substantially free of myofibrils and sarcomeres. The amount of oil and/or fat absorbed by the food during cooking is substantially reduced while the food retains its color and taste.

Disclosed are a fish protein oligopeptide with low allergenicity and slight fishiness, and industrial preparation method and application thereof. The method comprises the following steps: 1) washing fresh fish flesh and/or fish wastes, crushing, and adding water to obtain a mixture; 2) performing thermal denaturation on the mixture to obtain a denaturized protein solution; 3) centrifuging the denaturized protein solution to obtain a precipitate, and adding water into the precipitate and grinding, to obtain a slurry; 4) adjusting the slurry to pH 6-9, and sequentially adding a neutral protease, a papain and an alkaline protease to conduct enzymolysis, and after enzyme inactivation, to obtain an enzymatic hydrolysate; 5) centrifuging the enzymatic hydrolysate, and performing membrane filtration on centrifuged supernatant, to obtain the fish protein oligopeptide with low allergenicity and slight fishiness. The method completely eliminates the allergenicity and fishiness of fish proteins, and prevents release of bitter components.
