Abstract

The present invention was made in view of an object to produce a novel proteoglycan-containing material, and find a novel use and/or a superior effect of the proteoglycan-containing material. The present invention provides a proteoglycan-containing material obtained from fish cartilage, wherein the proteoglycan-containing material comprises an acidic saccharide component having a molecular weight of not less than 2000 kDa. The proteoglycan-containing material provides advantageous effects for skin-moisturizing and skin anti-aging, including a superior skin fibroblast proliferation effect, an effect of enhancing and improving the skin barrier function, an effect of enhancing and improving the skin's capability to produce collagen, a dermis-thickening inhibition effect, and the like.

Claims

exact text as granted — not AI-modified
1 . A proteoglycan-containing material comprising proteoglycan and acidic saccharide as acidic saccharide components obtained from fish cartilage, wherein the proteoglycan-containing material comprises an acidic saccharide component having a molecular weight of not less than 2000 kDa. 
     
     
         2 . The proteoglycan-containing material according to  claim 1 , wherein the proteoglycan-containing material comprises an acidic saccharide component having a molecular weight of not less than 5000 kDa. 
     
     
         3 . The proteoglycan-containing material according to  claim 1 , wherein 50 mass % or more of acidic saccharide components have a molecular weight of not less than 2000 kDa. 
     
     
         4 . The proteoglycan-containing material according to  claim 1 , wherein 20 mass % or more of acidic saccharide components have a molecular weight of not less than 10000 kDa. 
     
     
         5 . The proteoglycan-containing material according to  claim 1 , wherein 20 mass % or more of acidic saccharide components is proteoglycan. 
     
     
         6 . A food or beverage composition comprising the proteoglycan-containing material according to  claim 1 . 
     
     
         7 . An oral composition comprising the proteoglycan-containing material according to  claim 1 . 
     
     
         8 . A cosmetic composition comprising the proteoglycan-containing material according to  claim 1 .
