The invention discloses a surfactant for cleaning
fruits and vegetables and a preparation method of the surfactant, and relates to the technical field of fruit and vegetable cleaning agents. Raw materials of the
cleaning agent comprise the following components: 10-15 parts of a modified surfactant, 2-3 parts of an
enzyme preparation, 1-2 parts of a cosolvent, 0.2-2 parts of a
viscosity modifier, 0.1-0.5 part of a bactericidal
preservative, 0.1-2.5 parts of a light stabilizer, 0.1-1.3 parts of an
antioxidant, 0.3 part of an emulsifier, 0.05-0.2 part of a bacteriostatic substance, 0.1-0.8 part of
sodium citrate, 5-7 parts of diatomite
powder, 2-8 parts of a
polyethylene glycol dispersant and 80-90 parts of deionized water. The preparation method comprises the following steps: firstly, adding a modified surfactant into deionized water, then sequentially adding an
enzyme preparation, a cosolvent, a bactericidal
preservative, a light stabilizer, an
antioxidant, an emulsifier, a bacteriostatic substance, diatomite
powder and a
polyethylene glycol dispersant into a reaction kettle, and continuously stirring and mixing to form a solution A; the fruit and vegetable cleaning surfactant prepared by the preparation steps has excellent detergency and a low-temperature residual
pesticide removal effect while having relatively good use safety.
