The purpose of the present invention is to provide a konjak gel with a shrimp-like texture, a shrimp-like food using the konjak gel, and a dried, shrimp-like food that has a shrimp-like texture and can be easily reconstituted using, for instance, hot water. This solution involves a porous structure-containing konjak gel including the following features (A) to (G): (A) a glucomannan content of 3.5 to 12 wt %; (B) a moisture content of 70 to 90 wt %; (C) a gel long side of 7 to 20 mm; (D) a gel thickness of 0.5 to 1.5 mm; (E) a porosity of 9 to 17% as measured for pores of 100 μm.sup.2 or larger in a gel cross section; (F) a largest pore porosity of 3 to 6% in the gel cross section; and (G) the gel having undergone freeze denaturation. The problem is also solved by a method for producing a shrimp-like food containing the konjac gel and a substrate made of glucomannan, or a shrimp-like, vacuum-freeze-dried food containing the konjac gel and a substrate containing a pulverized konjak gel material or a substrate containing a puffing agent.

The purpose of the present invention is to provide a container-packed composition in which a heat deterioration smell, such as a retort smell based on contained ingredients such as soy sauce, meat, and soybean protein, is reduced; a processed food using the composition and a method of producing the processed food; and a composition in which a smell specific to meat is suppressed, and a flavor of the meat is improved so as to impart umami of meat, regardless of the type of meat. The purpose is achieved by: a container-packed composition containing at least one ingredient selected from the group consisting of a seasoning component, vegetables, meat, and seafood and having a phenethyl acetate content of 1.0 ppb or more and less than 1,000 ppb; and a container-packed composition containing animal meat and having a phenethyl acetate content of 1 ppb or more and less than 1,500 ppb.

This application belongs to the field of biotechnology and discloses a method for producing a clam active peptide. The method for producing a clam active peptide comprises cleaning fresh clam meat with water, adding water and homogenizing with a colloid mill to prepare a clam meat slurry; adding water and complex protease for enzymolysis of the clam meat slurry, and heating to inactivate enzyme after the enzymolysis; centrifuging to collect an enzymatic hydrolyzate, capturing the enzymatic hydrolyzate having a molecular weight of lower than 2 KDa through microfiltration-ultrafiltration-nanofiltration membrane filtration, and drying to obtain the clam active peptide. The present disclosure produces a clam active peptide having pure color, outstanding taste, and blood pressure lowering function which is easily absorbed by human body using fresh clam meat as raw material, adopting a complex enzyme-membrane coupling technology through processing techniques such as enzymolysis, membrane separation purification and drying.

The invention concerns novel compositions, comprising at least 2 different sources of ω-3 fatty acids, including wherein hoki roe at 5% (w/w) in powder or oil form and green-lipped mussel in powder or oil form. The compositions are particularly useful as/in supplements and/or animal or human food stuffs. The invention may further relate to the maintenance or treatment of human and veterinary conditions, such as use in the improvement of inflammation or joint related disorders that maybe associated with inflammation.

A method for extracting high-quality krill oil from krill includes the following steps: S1. performing extraction on krill with an organic solvent, and collecting an extracting solution; S2. adding alkaline water to the extracting solution to enable a free fatty acid to form a fatty acid salt to be separated from an oil phase, and performing oil-water phase separation and collecting the oil phase; and S3. purifying the oil phase to obtain the high-quality krill oil. In the present application, the preparation process for krill oil is optimized, organic solvent extraction and alkali refining are ingeniously combined, and process parameters are adjusted and optimized, thereby reducing the acid value of krill oil, and also ensuring the content of active ingredients such as phospholipid and astaxanthin in krill oil to the greatest extent, and improving the quality of krill oil.

A labelling system includes a dispensing apparatus to present respective cut and opened sleeves of shrink-wrap label stock material for insertion of claws of crustaceans, and a heating apparatus to apply heat to the sleeves to shrink the sleeves around the claws. A related method includes inserting a claw of a crustacean into a sleeve of shrink-wrap label stock material, and applying heat to the sleeve to shrink the sleeve around the claw. Another method involves providing a dispensing apparatus to present respective cut and opened sleeves of shrink-wrap label stock material to receive claws of crustaceans, and providing a heating apparatus to apply heat to the sleeves to shrink the sleeves around the claws. A seafood product may include a crustacean having a claw, the claw carrying a shrink-wrap label.
