STUDY OF THE BLOWING PROPERTIES OF SOLUTIONS OBTAINED FROM PINE NUT SHELL BY AN ALTERNATIVE EXTRACTION METHOD

Abstract

The article discusses the possibility of obtaining a tanning extract from pine nut shells using water-alkaline extraction in the presence of acetone. The technological properties of the spiked extract were evaluated by the method of trial tanning of fur sheepskin. The prospect of using this extract in the leather and fur industry has been established, however, the processing technology using this extract requires additional refinement in terms of quality indicators.
