Abstract
Official abstract text for this publication.
A food discoloration inhibitor contains, as an effective ingredient, a low molecular weight lignin having a molecular weight peak in a molecular weight range of 4,000 to 9,500 and/or a high molecular weight lignin having a molecular weight peak in a molecular weight range of 10,000 to 40,000, wherein the molecular weight peak is measured at a wavelength of 254 nm by GPC molecular weight analysis using an UV detector.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of inhibiting food discoloration, comprising bringing in contact with a food a food discoloration inhibitor, comprising, as an effective ingredient, a low molecular weight lignin having a molecular weight peak in a molecular weight range of 4,000 to 9,500 and/or a high molecular weight lignin having a molecular weight peak in a molecular weight range of 10,000 to 40,000, wherein said molecular weight peak is measured at a wavelength of 254 nm by GPC molecular weight analysis using an UV detector. 2. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 1 , comprising, as an effective ingredient, a composition containing said low molecular weight lignin and/or said high molecular weight lignin, wherein the lignin(s) content, as a polyphenol amount, calculated using Folin-Chiocalteu method, is 0.05 wt % or more in terms of catechin. 3. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 2 , comprising, as an effective ingredient, said composition further containing a coumaric acid and/or a ferulic acid. 4. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 2 , wherein said composition is a bagasse alkaline hot-water extract. 5. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 1 , wherein the food is a fresh food. 6. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 5 , wherein said fresh food is an aquatic organism. 7. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 6 , wherein said aquatic organism is a crustacean. 8. A method of inhibiting food discoloration, comprising bringing in contact with a food the food discoloration inhibitor according to claim 7 , wherein said crustacean is a prawn.
