<p>Disclosed is a novel active oxygen annihilating agent in the form of a syrup or powder suitable as an additive to health foods to reduce noxious influences of active oxygen against human body. The active oxygen annihilating agent is prepared from locust bean pods having heretofore little utilizability but to be discarded as an agricultural waste material. Thus, crushed particulates of locust bean pods are subjected to an extraction treatment with water or ethyl alcohol and the extract solution is concentrated by evaporating at least a part of the solvent to give a syrup which can be freeze-dried or spray-dried into a powder. The syrup can be processed, for example, into a delicious jam for spreading over bread.</p> |
