Abstract

The invention discloses a preparation method of a green cleaning agent for a kitchen. The preparation method comprises the following steps: degrading corn starch in water by using high-temperature alpha-amylase, then carrying out graft copolymerization reaction with polyoxyethylene ether methacrylate under the action of an initiating agent to prepare a green starch-based surface active agent, and then compounding with soluble chitosan, sodium tripolyphosphate and sodium carbonate to obtain the green cleaning agent for the kitchen. The green cleaning agent for the kitchen, which is obtained by adopting the method, can be used for cleaning tableware, fruits, vegetables and the like and has the characteristics of good washing detergence property, sterilization, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the technical field of green cleaning agents, and in particular relates to a preparation method of a kitchen green cleaning agent. Background technique [0002] Kitchen detergent is mainly used for washing tableware, vegetables, fruits, etc. It can quickly and efficiently remove grease, protein, starch and other dirt remaining on the surface of tableware, and can wash away pesticides, microorganisms, insect eggs, and other residues on the surface of vegetables and fruits. Dirt and dirt adhered to the soil have a proper bactericidal effect, and at the same time, they are less irritating to the skin and are safe and harmless to the human body. The main components currently used in kitchen cleaning agents are fatty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate, sugar-based fatty acid ester, etc., and their main raw materials come from petrochemicals. Therefore, the use of renewable natural resources such as starch...
