Autofluorescence quantifies collagen in sausage batters with a large variation in myoglobin content.

In order to clarify the potential of the method of autofluorescence for determining the collagen content in meat batter, an experimental design was used where the emission originating from collagen was unrelated to the effect of myoglobin absorbance on the emission spectra. Muscles like beef Masseter, beef Latissimus dorsi and pork Glutens medius assured a large variation in myoglobin content, and made absorbance from myoglobin account for 65-84% of the variation in the emission spectra at wavelengths normally thought interesting for collagen quantification. Collagen (range 1.
