title: Improved method for determination of light filth in chocolate products.
abstract: The recovery of rodent hairs from chocolate has been significantly improved by the introduction of an additional defatting step, substitution of 40% isopropanol for water, and substitution of mineral oil-heptane (85+15) for heptane in the trapping-off step. These changes have no adverse effect on insect fragment recovery. An average recovery of 95% was obtained for rodent hairs, coefficient of variation 7.9%. Insect fragment recoveries were 100%.
