Abstract
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:=(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**(3)*(1−3))}/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).
