4. Conclusions
Chicken skin has a higher fat content as compared to chicken meat.
The difference in fat composition between chicken skin and meat has
an effect on the buffering capacity of these components. However, in
addition to fat composition other components, such as proteins,may influence
the buffering capacity of chicken skin and meat. Extracted fat
alone and skin remnants alone were not able to contribute to a strong
buffering capacity but when the components occur together a strong
buffering capacity was observed. Salmonella cells attached better to
chicken meat, skin and their respective remnants than fat probably because
the surface of extracted fat is not as rough as these components.
Skin remnantswere better at protecting attached Salmonella fromacetic
acid than other components.We suggest the fat content present in the
skin may increase the vulnerability of attached cells to acetic acid
