Abstract and keywords

Abstract:
The research results on the improvement of the tanning extract technology from low-quality raw materials with receiving the product with a high yield (up to 59%) and quality (good quality - 67%) are presented in the article. It is achieved by the use of the water-alkaline extractant and the combined method ofthe obtained extract refining (neutralization, sulphitation,ultrafiltration).
