PROBLEM TO BE SOLVED: To obtain conveniently and economically the subject beverage, which contains various nutrients of pine-needles as they were, without many stages for extracting and diluting pine-needle extract, by mixing pine needles with licorice, honey and water, and extracting the pine-needle extract in a specific extractor. SOLUTION: This method for producing a pine-needle extract beverage comprises mixing 85.3-89.3wt.% of water with a mixture of 5-7wt.% of pine needles and natural neutral materials such as 0.5-0.6wt.% of licorice and 4.4-6wt.% of honey, etc., charging the mixture into an extractor, then gradual heating up to 100-120 deg.C, air-cooling down to 80-90 deg.C, and subsequently reheating up to 100-120 deg.C the mixture, maintaining preferably the mixture in this temperature range for 5hr, filtering the thus obtained extract. In addition to licorice and honey, it is preferable to add, as natural neutral materials, one or more of 0.2-0.3wt.% of litchi, 0.5-0.6wt.% of dry black soybean, 0.1-0.2wt.% of dry cinnamon. Furthermore, a preferable extractor has three-shell structure constituted of an outside shell for heat insulation, intermediate shell for steam heating, and inside shell for charging the materials. |
