Abstract Thirteen trade samples of ice cream were collected from the local market to study their chemical composition and to compare that with experimental samples. Results obtained revealed that : 1) Total solids of the mix :- This varied between 19.464 to 39.286 % 2) fat :- Its percentage varried greatly from 1.5-9.2% .the low figure was commonely in samples collected from the vendors. 3) solids not fat :- It varied between 0.567 to 11.902 % 4) Ash :- The ash of some samples was 0.202% while in some others it was 1.191 % . But the experimental samples were from 0.991 to 1.114% . 5) Acidity varied from 0.01 to 0.45 % and consequently PH changed from 7.4 to 4.55. 6) Density :- The density of market ice cream varied from 0.697 to 0.892 G/cm3 . Whereas the density of the mix varied from 1.018 to 1.123 G/cm3. |
