[Determination of formaldehyde content in artificial cellulose casings by the colorimetric method with acetylacetone].

Artificial cellulose casings destined for production of processed pork were studied for their ability of formaldehyde release by a colorimetric method with acetylacetone. The studied material comprised 24 samples of colourless imported cellulose casings. The migration of formaldehyde into distilled water under conditions laid down in the BGA regulations (Empfehlung XLIV) was not exceeding 0.5 mg/dm3.
