Abstract
Official abstract text for this publication.
A nutrient composition contains a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1. The cellulose acetate may have a compositional distribution index (CDI) of 2.0 or less, where the CDI is specified by the formula: CDI =(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) where the measured value of half height width of chemical composition represents the half height width of chemical composition determined by HPLC analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate (sample); and [Math. 1] the theoretical value of half height width of chemical composition =2.35482√{square root over (3* DPw *( DS/ 3)*(1− DS/ 3))}/ DPw where DS is the total degree of acetyl substitution; and DPw is a weight-average degree of polymerization determined by a GPC-light scattering method using a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate (sample).

The invention claimed is: 1. A nutrient composition comprising a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1, wherein the cellulose acetate comprises a cellulose acetate material prepared under effective hydrolysis and precipitation conditions to obtain a compositional distribution index (CDI) of 2.0 or less, where the compositional distribution index is specified by the formula: CDI =(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) wherein: the measured value of half height width of chemical composition is a half height width of chemical composition determined by high-performance liquid chromatographic (HPLC) analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material; and the theoretical value of half height width of chemical composition is specified by a formula Math.1: [Math.1] Theoretical value of half height width of chemical composition =2.35482√{square root over (3* DPw *( DS/ 3)*(1− DS/ 3))}/ DPw wherein: DS is the total degree of acetyl substitution; and DPw is a weight-average degree of polymerization determined by a gel permeation chromatography (GPC)-light scattering method using a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material. 2. A livestock feed comprising a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1, wherein the cellulose acetate comprises a cellulose acetate material prepared under effective hydrolysis and precipitation conditions to obtain a compositional distribution index (CDI) of 2.0 or less, where the compositional distribution index is specified by the formula: CDI =(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) wherein: the measured value of half height width of chemical composition is a half height width of chemical composition determined by HPLC analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material; and the theoretical value of half height width of chemical composition is specified by a formula Math.1: [Math.1] Theoretical value of half height width of chemical composition =2.35482√{square root over (3* DPw *( DS/ 3)*(1− DS/ 3))}/ DPw wherein: DS is the total degree of acetyl substitution; and DPw is a weight-average degree of polymerization determined by a GPC-light scattering method using a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material. 3. A lipid metabolism-improving agent comprising a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1, wherein the cellulose acetate comprises a cellulose acetate material prepared under effective hydrolysis and precipitation conditions to obtain a compositional distribution index (CDI) of 2.0 or less, where the compositional distribution index is specified by the formula: CDI =(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) wherein: the measured value of half height width of chemical composition is a half height width of chemical composition determined by HPLC analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material; and the theoretical value of half height width of chemical composition is specified by a formula Math.1: [Math.1] Theoretical value of half height width of chemical composition =2.35482√{square root over (3* DPw *( DS/ 3)*(1− DS/ 3))}/ DPw wherein: DS is the total degree of acetyl substitution; and DPw is a weight-average degree of polymerization determined by a GPC-light scattering method using a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material. 4. The lipid metabolism-improving agent according to claim 3 , wherein the agent is for livestock. 5. An improving agent for inflammatory bowel diseases or immune disorder, the agent comprising a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1, wherein the cellulose acetate comprises a cellulose acetate material prepared under effective hydrolysis and precipitation conditions to obtain a compositional distribution index (CDI) of 2.0 or less, where the compositional distribution index is specified by the formula: CDI =(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) wherein: the measured value of half height width of chemical composition is a half height width of chemical composition determined by HPLC analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material; and the theoretical value of half height width of chemical composition is specified by a formula Math.1: [Math. 1] Theoretical value of half height width of chemical composition =2.35482√{square root over (3* DPw *( DS/ 3)*(1− DS/ 3))}/ DPw wherein: DS is the total degree of acetyl substitution; and DPw is a weight-average degree of polymerization determined by a GPC-light scattering method using a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate material. 6. The improving agent according to claim 5 for inflammatory bowel diseases or immune disorder, wherein the agent is for livestock.
