Benefits of technology

The present invention relates to identifying certain sugars that can prevent the growth and acid production of a specific type of dental plaque bacteria, which causes tooth dental plaque. This discovery can be applied to create various oral hygiene products, foods, and medicines to help prevent dental plaque buildup.

Problems solved by technology

Due to these merits, xylitol is currently produced as gum, toothpastes, and the like and widely used, but it is disadvantageous in that the growth of Streptococcus mutans can be suppressed only in the case of including xylitol at a high concentration.
However, research results on natural sugars which have an anticariogenic effect as much as xylitol are insufficient.

Production of Agarooligosaccharides Through Phosphoric Acid Hydrolysis of Agarose

[0073]Agarose was dissolved in 2% phosphoric acid at a concentration of 30.7% (w / v) and a reaction was allowed to occur therebetween using a microwave digester at 110° C. for 10 minutes, and then the acid-hydrolyzed reaction product was neutralized using 5 M NaOH such that the reaction product had a pH of 5 to 6. The reaction product was lyophilized to obtain powder-type agarooligosaccharides.

Production of Neoagarobiose Using Aga16B and Aga50D

[0074]5% agarose was prepared using 200 mL of a 20 mM Tris-HCl buffer (pH 7.0) and dissolved in an autoclave at 121° C. for 10 minutes, and then 19.7 mg of Aga16B (see Korean Patent Application No. 2016-0006589) was added thereto in order to degrade the agarose, and a reaction was allowed to occur therein at 55° C. and 200 rpm for 12 hours, thereby obtaining neoagarotetraose and neoagarohexaose as reaction products. Each reaction product was allowed to react with...

Abstract

The present invention relates to a use of an agarobiose or agarooligosaccharides having anticariogenic activity. More specifically, a lower concentration of agarobiose or agarooligosaccharides than the concentration of xylitol suppresses the growth of Streptococcus mutans and suppresses acid production, and thus can be used for anti-cariogenic purposes.

Description

BACKGROUND1. Field of the Invention[0001]The present invention relates to a use of agarobiose or agarooligosaccharides having an anticariogenic activity.2. Discussion of Related Art[0002]Dental caries is one of the main causes of people visiting dentists and its incidence rate has increased due to the use of sugar as a sweetener in modern society. Streptococcus mutans is a major causative bacterium of dental caries (Loesche W J et al. (1975) Infect Immun. 11(6): 1252-60). Streptococcus mutans, which is a bacterium that resides in the human mouth, breaks sugar down, and secretes a glucosyltransferase (GTF) to form insoluble glucans on the tooth surface. Streptococcus mutans or various other bacteria are attached to the tooth surface to proliferate thereon. Bacteria on the tooth surface cause tooth decay as the enamel of the tooth surface is damaged by an organic acid such as lactic acid, which is a carbohydrate metabolite (Dashper S. G., et al. (1996) Microbiol. 142, 33-29). As repre...
