The present invention describes about the method of making a food washing/cleaning formulation for fresh/cut vegetables, fruits, meat, poultry and seafood commodities before their consumption by mankind. This patent addresses the problem and attempt to provide the solution by providing a process for making a food wash formulation at a very low cost suitable and affordable by the people of low income countries thereby the product can be used by anyone on daily basis to safe guard their health against disease causing microbial pathogens and hazardous agro chemicals and other forms of toxins. The active ingredients are chosen in a way that they effectively cleans & lowers the heavily contaminated microbial load as well as to remove the residual chemicals associated with the plant and animal products used as food for their consumption. The active ingredients includes the powered form of food grade bentonite which has been conjugated with either of histidine or Chitosan with the property of adsorbing any positively charged agro chemicals, mycotoxins, dusts and the edible form of sodium per carbonate which effectively kills the microbes and decontaminate the animal and plant derived food product surfaces upon treatment for minimum of 20 minutes duration. The resulting wash with precipitated waste could be used in the garden plants since Bentonite, hydrogen peroxide and traces of pesticides are helpful in boosting the plant growth, soil fertility and considered as completely safe for man and his environment.
