The scavenger can be used for preparing a cleaning agent for fruit and vegetable, health food and additive of pickled vegetable or pickled food. The scavenger can not be damaged and failed due to the influence of high temperature, and has good scavenging effect under the condition that the pH is 2.0-10.0. The scavenger is a pure natural extracting solution without any toxic and side effects, wherein the scavenging effect of 5.5g of Chinese onion or an equal amount of extract is equivalent to that of 100mg of vitamin C. The preparation method has simple operation and low production cost. The cleaning agent for fruit and vegetable, health food or food additive prepared from the scavenger have no toxic or side effect on the human body, and can realize an effect of scavenging the nitrite quickly (in 3 minutes).

Description

technical field [0001] The invention relates to the field of food, in particular to a nitrite scavenger and its preparation method and application.
