DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antibacterial agent and a deodorant, and more specifically, to deodorization and deodorization of malodorous components which may be present in a living environment such as food and drink, cosmetics and daily necessities, and microorganisms. The present invention relates to an antibacterial agent and a deodorant containing, as an active ingredient, an extract of a Rosaceae plant, which suppresses the propagation of microorganisms and prevents microbial contamination.

[0002]

2. Description of the Related Art In recent years,
Prevent the generation of unpleasant odors and prevent microbial contamination and proliferation of foods and drinks that are eaten by humans, cosmetics and other things that are directly attached to the skin, and everyday goods that can be present in the living environment. The desire to do so has increased, and in fact, these harmful substances have caused damage to daily life.

[0003] In this case, as means for preventing the generation of unpleasant odors such as malodorous components and for eliminating the generated unpleasant odors, a method of masking unpleasant odors with an aromatic substance, neutralizing a substance causing the unpleasant odors, Various methods have been proposed, such as a method of deodorizing by oxidative decomposition and other chemical reactions, and a method of immobilizing by adsorbing on an adsorbent such as activated carbon.

Means for preventing the growth and contamination of microorganisms include methods of killing the microorganisms by physical treatment such as heat treatment, methods of using disinfectants such as alcohols and chlorine agents, benzoic acid and sorbin. A method of suppressing the growth of microorganisms using an antibacterial agent such as an acid has been attempted.

[0005] However, when antibacterial agents and deodorants using these synthetic compounds are used in foods and drinks and cosmetics, there is a problem in terms of safety. In addition, there is a problem in that adding an amount that provides a sufficient effect increases the influence on the flavor and the feeling upon use. Furthermore, when used for daily necessities, etc., there is a problem of environmental pollution.

[0006] Therefore, to prevent bad breath, to improve the flavor of food and drink,
For the purpose of preventing bad smell of pet animal manure, food, feed,
Research is being pursued on highly safe plant extracts from deodorants that can be added to feeds and oral preparations. For example, a deodorant containing a green tea extract (Japanese Patent Publication No. 58-18098), an oolong tea extract, a radish extract, a persimmon tannin, a soybean / cereal extract, a spice extract, or the like as an active ingredient has been proposed.

On the other hand, various studies have been made on the use of highly safe natural plant extracts for antibacterial agents. For example, natural tree extract (JP-A-9-154929), wasabi extract, mustard extract (JP-A-2000-5)
No. 1339), extracts of the leaves of the genus Sasa genus Bamboo (JP-A-9-48925), wormwood extract, green tea extract (JP-A-11-228325), and extracts of cedar and the like (JP-A-10-305088). Publication).
