Problems solved by technology

[0003] In addition, for family bathrooms, due to the tight sealing and poor air flow, most bathroom sewer pipes do not have sealing devices, even if there is a sealing effect, it is not very ideal, resulting in odors in the bathroom. These odor components are mainly hydrogen sulfide, ammonia, and sulfur dioxide. etc. These gases not only affect human health, but also affect human living environment and quality of life
Most of the deodorants currently in use are plant extraction or chemical synthesis. The plant extraction process is complicated, the production cost is high, and the people are not easy to accept; whether chemical synthesis is harmful to the human body, whether there is secondary pollution, or whether it has corrosion is unknown.

Abstract

The invention discloses a preparation method of a nanometer starch deodorant, comprising the following steps: (1) adding an appropriate amount of starch into a buffer solution, heating in a boiling water bath, and gelatinizing sufficiently to obtain a starch solution; (2) enzymatically hydrolyzing the gelatinized starch solution for a certain time, and then heating to terminate the enzyme activityto obtain product A; 3) centrifuge product A, crystallizing, filter and vacuum drying to obtain nanometer starch particles; and 4) ultrasonic washing the obtained nanometer starch particles to prepare the nanometer starch deodorant. The nano-starch deodorant prepared by the preparation method has the advantages of wide source of raw materials, easy obtaining, low cost, good effect, and can effectively remove peculiar smell, thus being environment-friendly and free from any side effects; and the preparation method of the nanometer starch deodorant has the advantages of mild condition, simple procedure, low cost and environmental protection.

Description

technical field [0001] The invention relates to a preparation method of a deodorant, in particular to a preparation method of a nano starch deodorant. Background technique [0002] The so-called nano-starch deodorant is an environmentally friendly product, which has excellent enzyme-producing properties, can effectively capture and degrade odor-causing substances, and convert them into benign cellular components and odorless carbon dioxide and water. Nano starch deodorant is widely used in organic waste treatment, for example: it can be used in sewage treatment, which can effectively degrade the peculiar smell produced by sewage; in landfill, it can effectively degrade the peculiar smell produced by garbage; pet deodorization: it can effectively decompose pet odor It can quickly remove the peculiar smell of smoke and leather in a certain space; it can effectively control the peculiar smell in the room (home, hotel, club, etc.), and provide long-term odor control by removing ...
