PURPOSE:To obtain the titled food raw material rich in nutrient components, by adding a specific additive in the rough crushing process of edible bone and marrow, pulverizing the bone, etc. to ultra-fine powder, removing the blood and fat therefrom, and adding an additive to adjust the pH. CONSTITUTION:The edible bone and marrow of cattle, poultry or fish are crushed to a proper size, immersed in a solution of sodium hypochlorite to effect the disinfection and cleaning, roughly crushed to 1-5mm. diameter, added with an alkaline aqueous solution of soybean lecithin, stirred homogeneously, and pulverized with a precise grinder to ultra-fine powder of <=5mu diameter under the temperature condition to prevent the thermal denaturation of the proteins which are the main components of the product. The powder is washed with water chilled at <=15 deg.C, dehydrated to a proper water-content, subjected to the removal of blood and fat, mixed with an aqueous soluton of soybean lecithin, and adjusted to 5.3-6pH with an organic acid. The obtained pasty mince having low fat content and free from the dripping tendency is freeze-dried or dried with hot air to obtain the powdery material. |
