Description

Method for producing a plant extract with enhanced flavonoid content and an odor removal composition containing the same The present application relates to a method for preparing a plant extract with enhanced flavonoid content and an odor removal composition comprising the same. Malodors are caused by sulfur-based compounds such as hydrogen sulfide, methyl sulfide, and methyl mercaptan, or nitrogen-based compounds such as ammonia and trimethylamine. Methods for removing malodors include using porous materials such as activated carbon, zeolite, and silica gel to adsorb odor components, chemically reacting odor components with deodorizing agents to deodorize them, or using aromatic substances such as fragrances to block odors. However, when chemically synthesized ingredients are used for odor removal, harmful substances can be absorbed through the respiratory system or come into contact with the skin, causing irritation. Consequently, methods to eliminate odors using naturally derived ingredients that are harmless to the human body are currently being researched. The structural or functional descriptions of the embodiments disclosed in this specification are merely illustrative for the purpose of explaining embodiments according to the technical concept of this application. Furthermore, embodiments according to the technical concept of this application may be implemented in various forms other than those disclosed in this specification. Additionally, the technical concept of this application is not to be interpreted as being limited to the embodiments described in this specification. Among the physical properties mentioned in this specification, if the measurement temperature affects the property, the property is the one measured at room temperature and pressure unless otherwise specifically stipulated. Unless otherwise specifically defined among the physical properties mentioned in this specification, said physical properties may basically follow the SI unit system. For example, weight may be expressed in kg units, and length may be expressed in m units. The term "room temperature" as used in this specification refers to a natural temperature that is not heated or cooled, and may mean, for example, any temperature within the range of 10°C to 30°C, for example, about 15°C or higher, about 18°C or higher, about 20°C or higher, about 23°C or higher, about 27°C or lower, or 25°C. Unless specifically defined in this specification, the unit of temperature is Celsius (°C). The term "relatively high temperature relative to room temperature" as used in this specification refers to a temperature higher than room temperature, and may mean, for example, any temperature within the range of 30°C to 50°C, for example, about 35°C or higher, about 40°C or higher, or about 45°C or lower. Among the physical properties mentioned in this specification, if the measured pressure affects the physical property, unless otherwise specifically defined, the physical property is the property measured at atmospheric pressure. The term atmospheric pressure used in this specification refers to natural pressure that is not pressurized or depressurized, and typically refers to atmospheric pressure within the range of about 700 mmHg to 800 mmHg. As used in this specification, the terms a to b refer to a range between a and b, including a and b. For example, including a to b parts by weight is equivalent to including within the range of a to b parts by weight. In this specification, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but the components are not limited by the terms. The terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the rights of this application, the first component may be named the second component, and similarly, the second component may be named the first component. The term "and/or" includes a combination of a plurality of related items or any one of a plurality of related items. The terms used herein are for describing embodiments and are not intended to limit or/or restrict the present application. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as "comprising" or "having" are intended to indicate the presence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Hereinafter, exemplary embodiments according to the present application will be described in detail. According to an embodiment of the present application, a method for preparing a plant extract with enhanced flavonoid content is provided. The method may include the step of first extracting a plant by steam distillati
