Claims21
An absorbent article for absorption of body fluids, comprising an absorbent member that comprises at least one non-crosslinked plant protein based absorbent material comprising plant protein, wherein said plant protein is aggregated and acylated, and
- wherein said at least one non-crosslinked plant protein based absorbent material is obtainable by a method comprising steps of
- i. providing a mixture or suspension comprising a liquid and a plant protein, wherein said plant protein is sufficiently aggregated so as to be insoluble in the liquid,
- ii. acylating said plant protein by adding an acylating agent thereto, and
- iii. obtaining said at least one non-crosslinked plant protein based absorbent material.
An absorbent article for absorption of body fluids, comprising an absorbent member, wherein the absorbent member comprises at least one non-crosslinked plant protein based absorbent material comprising plant protein, wherein the plant protein is aggregated and acylated, and wherein the at least one non-crosslinked plant protein based absorbent material has a free swelling capacity (FSC) of at least 3 g of 0.9 wt. % NaCl solution per gram absorbent material at 10 seconds.
