息香酸、ソルビン酸、プロピオン酸、サリチル酸などの
多数の合成品が知られているが。Many synthetic products such as benzoic acid, sorbic acid, propionic acid, and salicylic acid are known as antibacterial agents, preservatives, and disinfectants for foods and cosmetics.
これらの合成品は人工品であるため安全性に問題を生じ

ている（特開昭５９−４６２２３号。To improve this point, antibacterial and bactericidal agents containing chitosan, which is obtained by deacetylating the chitin contained in the shells of crustaceans such as shrimp and crabs, as an active ingredient have recently been proposed (especially Kaisho 59-46223.
特開昭６２−８３８７７号）。JP-A No. 62-83877).

本発明は上記従来技術の事情に鑑みてなされたものであ
って、その目的とするところは低濃度で抗菌性を示し、
しかも細菌のみならず酵母に対しても著しい生育及び増
殖抑制効果を発揮する酵母あるいは細菌の生育および増
殖抑制剤を提供することにある。However, such antibacterial agents and bactericidal agents that have chitosan as their main ingredient have insufficient antibacterial effects and must be used in large quantities in order to exhibit their antibacterial effects, and they also have a negative effect on the growth and proliferation of yeast. The present invention was made in view of the above-mentioned circumstances of the prior art, and its purpose is to exhibit antibacterial properties at low concentrations,
Moreover, it is an object of the present invention to provide a yeast or bacterial growth and proliferation inhibitor that exhibits a remarkable growth and proliferation inhibiting effect not only on bacteria but also on yeast.
本発明者等らはキトサンを主体とする酵母あるいは細菌

乗効果を奏することを見い出し、本発明を完成するに至
った。As a result of intensive research into yeast or bacterial growth and proliferation inhibitors mainly composed of chitosan, the present inventors discovered that a combination of chitosan and ascorbic acid produces an excellent synergistic effect, thereby completing the present invention. reached.
即ち、本発明の酵母あるいは細菌の生育及び増殖抑制剤
はキトサンとアスコルビン酸を有効成分としたことを特
徴とする。That is, the yeast or bacterial growth and proliferation inhibitor of the present invention is characterized by containing chitosan and ascorbic acid as active ingredients.
本発明で用いるキトサンは、従来公知のものが適用でき

の水酸化ナトリウム水溶液に浸漬し、５０〜１３０℃で
反応させた後、アルカリを除去し、次いで水洗乾燥して
得られたフレーク状、又はさらに粉砕工程を経た粉末状
のキトサンがある。As the chitosan used in the present invention, conventionally known chitosan can be used, such as chitosan obtained by deacetylating commercially available chitin or naturally occurring chitin by a conventional method. An example of the latter is, for example, chitin obtained by demineralizing and deproteinizing crab shells at a concentration of 40 to 50%.
There are chitosan in the form of flakes obtained by immersing the chitosan in an aqueous solution of sodium hydroxide, reacting at 50 to 130°C, removing the alkali, washing with water and drying, or in the form of a powder which is further subjected to a pulverization process.
キトサンは、脱アセチル化率が７０％未満のものでは溶
解性に乏しいことから少なくとも脱アセチル化率が７０
％以上であることが望ましい。Chitosan has poor solubility when the deacetylation rate is less than 70%, so chitosan must have a deacetylation rate of at least 70%.
% or more is desirable.
また、本発明においてはキトサンの分子量が小さいと細
菌、および酵母に対する生育、増殖の抑制効果が小さく

（Ｂ型粘度計による粘度）が５０ｃｐ。Furthermore, in the present invention, if the molecular weight of chitosan is small, the effect of inhibiting the growth and proliferation of bacteria and yeast will be reduced, so the viscosity (viscosity by B-type viscometer) of a 1% aqueous solution of chitosan at 25° C. is 50 cp.
好ましくは１００ｃｐ以上のものが用いられる。Preferably, one having a value of 100 cp or more is used.
アスコルビン酸は、Ｌ−アスコルビン酸及びイソアスコ
ルビン酸が好適に使用される。このアスコルビン酸の使
用形態は、特別に制約されないが、粉末状、あるいは水

ビン酸の混合比率は重量比で１：０．９〜３．０、好ま
しくは１：１．Ｏ−２，０である。As the ascorbic acid, L-ascorbic acid and isoascorbic acid are preferably used. The form in which this ascorbic acid is used is not particularly limited, but it is desirable to use it as a powder or an aqueous solution. The mixing ratio of chitosan and ascorbic acid is 1:0.9 to 3.0 by weight, preferably 1:1. It is O-2.0.

、医薬、化粧料等の巾広い分野に好適に利用される。Since the yeast or bacterial growth and proliferation inhibitor of the present invention contains chitosan and ascorbic acid as active ingredients, its antibacterial activity is lower in concentration than chitosan alone or chitosan in combination with an acid such as acetic acid or lactic acid. Furthermore, it exerts a remarkable growth and proliferation inhibitory effect not only on bacteria but also on yeast. Therefore, the yeast or bacterial growth and proliferation inhibitor of the present invention is, for example, an antibacterial agent for marine products such as shrimp, sea bream, and fish fillets, a preservative for processed products such as shumai and kamaboko, and a disinfectant for vegetables and fruits. meat,
It is suitably used in a wide range of fields including food, medicine, cosmetics, sterilization of food processing equipment for seafood, disinfectants, anti-dandruff agents such as shampoos and conditioners, and therapeutic agents for candidiasis.

The yeast shown in No. 1 was planted and cultured at 25° C. for 48 hours, and the formation of turbidity was observed. Those with turbidity were rated as (+), and those with no turbidity were rated as (−).
