Abstract

The invention relates to a method for improving palatability of caragana feed. The method comprises the following steps of (1) pretreatment: crushing caragana plants, adding water, uniformly mixing, and preparing an extract; (2) pressurizing treatment: putting the extract in a pressurizing reaction kettle, carrying out pressurizing extraction by using CO2 (carbon dioxide) under the pressure of 1-100MPa for 15 to 30 minutes so as to obtain the pressurized extract; (3) filtrate filtering: filtering the pressurized extract in the step (2), and removing the filtrate to obtain caragana solid particles; and (4) drying: drying the caragana solid particles in step (3) to finally obtain the caragana feed with high palatability. The method has the advantages that the steps are completed at normal temperature and high pressure, the removal rate of tannin from the cargana plants is high by the pressurizing method and reaches more than 90%, the nutrient substances of the caragana plants are basically not consumed, the production technology is simple, the extraction time is short, the production efficiency is high, the energy consumption is reduced, and the practical value is high.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and relates to a method for removing tannins from fresh or naturally air-dried twigs, leaves and flowers of Caragana plants by adopting a pressurized process, in particular to a method for improving the palatability of Caragana feedstuffs. Background technique [0002] Caragana Fabr. is a deciduous shrub, a specialty of Eurasia, and a typical vegetation in the Eurasian steppe plant subregion. In my country, its cultivated species are generally called Caragana. There are more than 100 species distributed all over the world. my country has identified 66 species. Caragana has abundant resource advantages in the northwest of my country. Not only is the natural species distributed in a large area, but also the area of ​​artificially planted Caragana forest has grown rapidly in recent years. Caragana grows rapidly, is resistant to cold, drought, and barrenness, and has a strong and d...
