92 5 isovaleric acid 0 dimethyidisulfide 45 dimethyltrisulfide 24 triethylamine 77 indole and 60 skatole chitosan the deacetylated form of chitin was studied as a natural material to help abate odors chitosan version rns 022 from vanson films were prepared by dissolving the polymer in 2 acetic acid and casting a film using a doctor 39 s blade ten mg of chitosan acetate was able to absorb an average of 60 isovaleric acid 1 dimethyidisulfide 8 dimethyltrisulfide 44 triethylamine 90 indole and 67 skatole chitosan treated with 0 5 glucopon 220up alkyl polyglycoside from henkel corporation by weight was also fashioned into a film similar to the method described in comparative example 5 ten mg of that film was able to absorb an average of 97 of isovaleric acid 18 dimethyldisulfide 36 dimethyltrisulfide 34 triethylamine 84 indole and 58 skatole comparing example 5a to comparative example 5 demonstrates the ability of an alkyl polyglycoside to increase the ability of chitosan to absorb isovaleric acid by 61 dimethyldisulfide by 1800 and dimethyltrisulfide by 450 chitosan treated by adding 1 glucopon by weight was also fashioned into a film similar to the method described in comparative example 5 ten mg of that film was able to absorb an average of 99 of isovaleric acid 6 dimethyldisulfide 46 dimethyltrisulfide 54 triethylamine 92 indole and 74 skatole comparing example 6 to comparative example 5 demonstrates the ability of an alkyl polyglycoside to increase the ability.
