Natural surface active agent for cleaning fruits and vegetables and preparation method thereof

The invention relates to a natural surface active agent for cleaning fruits and vegetables, which is designed for overcoming the defects that the prior cleaning agent has non-thorough secondary cleaning, is harm to a human body after long terms of use, is not easily degraded, can cause secondary pollution, and the like. The natural surface active agent is prepared from the following components by weight percent: 10-40 percent of active matter extract of Chinese soaphberry with the concentration of 30-40 percent, 10-40 percent of alkyl poly-glycosides (APG) with the concentration of 47 percent, 10-30 percent of ginger extract with the concentration of 5 percent, 0.1-0.5 percent of EDTA, 0.3-1 percent of sodium chloride, citric acid and appropriate water. The method comprises the following steps: adding 20 percent of deionized water in a reaction vessel; heating to 35-40 DEG C, then sequentially adding APG, the active matter extract of Chinese soaphberry, the ginger extract and the EDTA, and fully mixing and stirring evenly during addition; adding appropriate citric acid; cooling to room temperature; adding appropriate sodium chloride, fully stirring for 0.5 hour and aging for 1.5 hours to obtain finished product; and bottling for leaving factory. The main components of the natural surface active agent are natural products and derivatives thereof, and the invention has the advantages of good cleaning effect, no residual, easy degradation, no stimulation to skin, no side effects, no secondary pollution to environment and environmental protection.
