Abstract

The tannins are polyphenolic components that are available at leaf, fruit, body and rind of the plants. They also find many applications in different fields in the industry depending on their chemical structures and the plant properties that they are obtained. There are many tannins used in the leather production as a tanning material. These tannins used in plant tanning or combined tanning procedures both minimize environmental effects of tanning procedure and allowfor eco-leather production. In this paper, tannin analysis was conducted on the plant extract in the powder form that was obtained from the rinds of pomegranate (Punica granatum) fruit brought up in Turkey and its usability as a tanning material in the leather sector was investigated. With this aim, pickled native sheep skins were used and the tanning processes were conducted in accordance with apparel leather production. The relevant physical tests and chemical analyses were carried out and compared to standard values. The research results revealed out that pomegranate rind extracts including averagely 37.2% tannin content are usable as tanning material, but it is required to modify and enhance its properties as vegetable tanning.
