| titleOfInvention | Method for extracting chlorogenic acid from jerusalem artichoke leaves |
| abstract | The invention provides a method for extracting chlorogenic acid from jerusalem artichoke leaves, which is characterized by comprising the steps that a. drying the jerusalem artichoke leaves at 60 DEG C to 95 DEG C until the moisture content is less than 10%, coursing crushing and sieving by a 60 mesh to 100 mesh sieve to obtain jerusalem artichoke leaf powder; b. placing the jerusalem artichoke leaf powder and alcohol into a countercurrent leaching device according to the weight part ratio of the jerusalem artichoke leaf powder obtained in the step a to the alcohol with the weight concentration of 60% to 80% of 1 to (5-10), carrying out the countercurrent leaching for 30 to 90min under the conditions that the pH value is 3.5 to 4.5 and the leaching temperature is 45 to 60 DEG C to obtain the leaching liquor; desolventizing, drying and crushing the wet meal of the jerusalem artichoke leaves after leaching to obtain feed; and c. filtering the leaching liquor obtained in the step b, concentrating the filtrate to paste and spray drying to obtain the product. The obtained chlorogenic acid has less impurities, the obtained product is safe and reliable to eat, and the chlorogenic acid can be further applied as functional foods or additives. |
