[0131] Hereinafter, although this invention is demonstrated more concretely, this invention is not limited to the following example.

[0132] Study on Extraction of Proteoglycan from Salmon Nasal Cartilage

[0133]

[0134] The following three samples ((1) to (3)) derived from salmon nasal cartilage were used for the extraction study of proteoglycan. It should be noted that, as salmon nasal cartilage, salmon nasal cartilage obtained by thawing the head of frozen salmon was used, and the nasal cartilage was taken out immediately, rinsed with running water for 6 hours to wash and degrease, and then, the flesh pieces, etc. were removed with tweezers. It is then obtained by hand washing.

[0135] (1) Frozen Salmon Nasal Cartilage Blocks

[0136] Preserve salmon nasal cartilage in a freezer and allow it to freeze to use as frozen salmon nasal cartilage blocks. It should be noted that although the size and weight of the frozen salmon nasal cartilage block are related to the size ...

Abstract

The objective of the present invention is to obtain a useful extract from aquatic animal tissues. The present invention provides a fish-cartilage water extract containing proteoglycans having molecular weights greater than or equal to 2,500,000. This extract has excellent anti-aging effects to the skin (particularly, anti-inflammatory effect, the effect of improving the barrier function of the skin, and the effect of improving the moisture retainability of the skin). Moreover, this fish-cartilage water extract achieves the aforementioned effects not only by application to the skin, but also through oral ingestion.

Description

technical field [0001] The present invention relates to aquatic animal cartilage extract. More specifically, the present invention relates to an extract of aquatic cartilage containing high molecular weight proteoglycan. Background technique [0002] Proteoglycan is a main biopolymer that forms a matrix in the extracellular matrix of connective tissue together with collagen and the like. In the past, proteoglycans were obtained by extracting and isolating substances contained in mammalian (especially bovine) cartilage. However, since the onset of bovine cerebral spongiform disease (BSE) has been reported, it is desirable to avoid proteoglycans from mammalian cartilage. Extraction requires a proteoglycan supply source to replace it. In addition, the previous proteoglycan extraction process is complicated and the yield is not high, so the production cost is very high, and the industrial application cannot be fully realized. Therefore, a more simple and high-yield production ...
