PURPOSE: A producing method of duck bone broth for retort pouch products is provided to provide the duck bone broth with low calorie, and excellent sweetness, flavor, and overall palatability. CONSTITUTION: 100 parts by weight of duck bones are mixed with 0.1-3 parts by weight medical herbs and 100-500 parts by weight of water, and extracted at 100-150°C for 2-6 hours. The medical herbs include Angelica gigas, Cnidii Rhizoma, Paeoniae Radix, and milk vetch root in a weight ratio of 1:1:1:1. The obtained extract is cooled to 20-50°C, and fat is removed from the extract with a filter net. The extract without the fat is filled in a retort pouch, and is retort-sterilized at 110-130°C for 5- 60 minutes. The sweetness of the obtained duck bone broth is 1.5-4 brix. |
