Description

【0001】
【発明の属する技術分野】本発明は、野菜及び果物などの青果物を洗浄する青果物用洗浄剤組成物、及びこの洗浄剤で洗浄した青果物に関するものである。
【0002】
【従来の技術】野菜、果物などの青果物は油や農薬、虫、土や砂、微生物などで汚染されていることが多く、安全衛生の面から食に供する前に、洗浄することが必要である。
【0003】
従来から、このような油、農薬、虫、土や砂、微生物などの異物を取り除くために、界面活性剤を主成分とした洗浄剤が主として使用されてきている。野菜及び果物などの青果物の洗浄剤としては、アルキルベンゼンスルホン酸塩、アルキルエーテル硫酸エステル塩などのアニオン性界面活性剤が主として使用されてきたが、これらの洗浄剤は洗浄力が優れているものの、すすぎが不十分な場合や青果物に吸着されて青果物中に残留した場合の毒性に懸念がもたれている。
【0004】
そこで、安全性を考慮して、食品用乳化剤として認可されている蔗糖脂肪酸エステルやポリグリセリン脂肪酸エステルなどの非イオン性界面活性剤を使用した洗浄剤が市販されている。しかしながら、これらの非イオン性界面活性剤を主成分とした洗浄剤は安全性の面では問題が無いものの、洗浄力が弱いという欠点を有しているために市場では殆ど受け入れられていないのが実状である。
【0005】
このため、洗浄力の改良を目的とした特許が出願されている。例えば特開昭50−39707では、蔗糖脂肪酸エステルとグリセリンモノ脂肪酸エステルを混合してなる洗浄剤組成物が提案されている。又特開平10−158690では、安全で洗浄効率が高く、かつ広い温度領域での保存安定性が良好な、カプリル酸モノグリセリド、蔗糖脂肪酸モノエステル、ビルダー、ハイドロトロープ及び糖類からなる洗浄剤組成物が提案されている。
【0006】
しかしながら、これらの配合においても現在のところ満足できる洗浄剤は得られていない。それゆえに、安全性や環境に対する配慮などの観点から、これらの洗浄剤の性能改良がより以上に期待されている。また野菜や果物などの青果物の洗浄剤による洗浄においては、表面を覆っている皮膜や油脂分が失われるため、本来持っている野菜や果物などの青果物の鮮度が失われていく欠点があり、この改良が更に求められている。
【0007】
【発明が解決しようとする課題】本発明は、洗浄効率が高く、かつ鮮度保持性及び安全性(抗菌効果)に優れた青果物用洗浄剤組成物及びこの洗浄剤で洗浄した安全な青果物の提供を目的とする。
【0008】
【課題を解決するための手段】本発明者らは、上記のように求められているような優れた安全性、洗浄効率及び鮮度保持性効果を有する洗浄剤組成物を開発すべく鋭意検討した結果、驚くべきことに(A)、(B)、(C)及び(D)成分を組み合わせることにより本発明を完成するに至った。
【0009】
本発明は、蔗糖脂肪酸エステル(A)及び/又はポリグリセリン脂肪酸エステル(B)10〜40重量%、トレハロース(C)2〜20重量%並びにポリリジン(D)0.05〜0.5重量%を主成分として含有することを特徴とする青果物用洗浄剤組成物、及びこの洗浄剤組成物で洗浄した青果物を提供する。
【0010】
本発明で用いられる蔗糖脂肪酸エステル(A)とは、蔗糖と脂肪酸とを反応させることにより得られるエステルで、脂肪酸としては炭素数12〜18のものが好適に用いられ、飽和脂肪酸でも不飽和脂肪酸でもかまわない。蔗糖に対する脂肪酸のエステル化度はモノエステルが好ましい。具体的な蔗糖脂肪酸エステルとしては、例えば、蔗糖ラウリン酸エステル、蔗糖ミリスチン酸エステル、蔗糖パルミチン酸エステル、蔗糖ステアリン酸エステル、蔗糖オレイン酸エステル、蔗糖リノール酸エステル等が挙げられ、好ましくは蔗糖ラウリン酸エステルである。
【0011】
本発明で用いられるポリグリセリン脂肪酸エステル(B)とは、ポリグリセリンと脂肪酸とを反応させることにより得られるエステルで、ポリグリセリンとしてはデカグリセリン、ヘキサグリセリン、テトラグリセリンなどが用いられ、脂肪酸としては炭素数12〜18のものが好適に用いられる。ポリグリセリンに対する脂肪酸のエステル化度はモノエステルが好ましい。具体的なポリグリセリン脂肪酸エステルとしては、例えばデカグリセリンオレイン酸エステル、デカグリセリンラウリン酸エステル、デカグリセリンステアリン酸エステル、ヘキサグリセリンラウリン酸エステル等が挙げられ、好ましくはデカグリセリンラウリン酸エステルである。
【0012】
本発明で用いられるトレハロース(C)とは、別名トレハ糖でグルコースが2分子よりなる二糖類の一つで、還元基どうしで結合したトレハロース型糖質であり、天然に存在するが、デンプンを原料として酵素を働かせての製造が可能な化合物である。「トレハオース」の商品名で市販されている。甘味料として用いられている非還元性糖質である。
【0013】
本発明で用いられるポリリジン(D)とは、L−リジンを構成単位とするポリアミノ酸であり、塩基性アミノ酸であるリジンの重合物である。ポリリジンの重合度は8以上が好ましい。具体的な例としてポリリジン(チッソ製)などに代表される市販のポリリジンが挙げられる。
【0014】
本発明に用いられる蔗塘脂肪酸エステル(A)及び/又はポリグリセリン脂肪酸エステル(B)の配合量は、10〜40重量%であり、好ましくは20〜30重量%である。10重量%未満では洗浄力が不十分で、40重量%を超えると組成物の粘度だ上がり過ぎて使い勝手が悪化するとともに組成物の安定性が悪化する。洗浄効果の面から(A)成分及び(B)成分を併用することが好ましく、(A)成分:(B)成分の使用比率は、1:1〜2:1が洗浄力及び使い勝手の観点から好ましい。
【0015】
本発明に用いられるトレハロース(C)の配合量は、2〜20重量%であり、好ましくは3〜10重量%である。2重量%未満では鮮度保持性が不十分で、20重量%を超えると、組成物の安定性が低下し、洗浄力も阻害される。
【0016】

【0017】
本発明の組成物には、使用の際の利便性から、水溶液又は水に可溶な有機溶剤の溶液の形態で使用することが好ましい。従って(A)、(B)、(C)及び(D)成分の合計が100重量%に満たない場合は、通常は水を加えて100重量%とする。かかる洗浄剤にあって洗浄力、安全性を損なわない限りで、香料、アルコール、着色料、プロピレングリコール等の粘度調節剤、水酸化ナトリウム等のPH調節剤、ビルダー、消泡剤等を添加することもできる。
【0018】
(A)〜(D)成分の添加順序は、特に限定されないが、先ず水に(C)成分と(D)成分とを溶かし、次いで(A)成分と(B)成分の界面活性剤を溶解するのが好ましい。混合する条件は、加熱して混合してもよいが、加熱に要するエネルギーの面からは、大気中、室温で行なうのが好ましい。混合には公知の混合機が用いられる。
【0019】

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition for fruits and vegetables, such as vegetables and fruits, and to fruits and vegetables washed with the detergent.
[0002]
2. Description of the Related Art Vegetables such as vegetables and fruits are often contaminated with oil, pesticides, insects, soil, sand, microorganisms, and the like. is there.
[0003]
Conventionally, in order to remove such foreign substances such as oils, pesticides, insects, soil, sand, and microorganisms, detergents containing a surfactant as a main component have been mainly used. As a detergent for fruits and vegetables such as vegetables and fruits, anionic surfactants such as alkyl benzene sulfonate and alkyl ether sulfate have been mainly used, but these detergents have excellent detergency, There is concern about the toxicity of insufficient rinsing or of adsorbed by fruits and vegetables and remaining in the fruits and vegetables.
[0004]
Therefore, in consideration of safety, detergents using nonionic surfactants such as sucrose fatty acid esters and polyglycerin fatty acid esters, which are approved as food emulsifiers, are commercially available. However, although these detergents containing a nonionic surfactant as a main component have no problem in terms of safety, they have a drawback that their detergency is weak, so they are hardly accepted in the market. It is a fact.
[0005]
For this reason, patents for the purpose of improving the detergency have been filed. For example, Japanese Patent Application Laid-Open No. 50-39707 proposes a detergent composition comprising a mixture of a sucrose fatty acid ester and a glycerin monofatty acid ester. JP-A-10-158690 discloses a cleaning composition comprising caprylic acid monoglyceride, sucrose fatty acid monoester, builder, hydrotrope and saccharide, which is safe, has high washing efficiency, and has good storage stability in a wide temperature range. Proposed.
[0006]
However, even with these formulations, satisfactory cleaning agents have not been obtained at present. Therefore, from the viewpoints of safety, environmental considerations, and the like, improvement in performance of these cleaning agents is more expected. In addition, the washing of vegetables and fruits with fruits and vegetables with a detergent has the disadvantage that the freshness of vegetables and fruits, such as vegetables and fruits, is lost because the film and oils and fats covering the surface are lost. There is a further need for this improvement.
[0007]
DISCLOSURE OF THE INVENTION The present invention provides a detergent composition for fruits and vegetables having high washing efficiency, excellent freshness retention and safety (antibacterial effect), and a safe fruit and vegetables washed with this detergent. With the goal.
[0008]
DISCLOSURE OF THE INVENTION The present inventors have intensively studied to develop a detergent composition having the excellent safety, washing efficiency and freshness maintaining effects as required above. As a result, surprisingly, the present invention has been completed by combining the components (A), (B), (C) and (D).
[0009]
The present invention relates to 10 to 40% by weight of sucrose fatty acid ester (A) and / or polyglycerin fatty acid ester (B), 2 to 20% by weight of trehalose (C) and 0.05 to 0.5% by weight of polylysine (D). A detergent composition for fruits and vegetables characterized by containing as a main component, and fruits and vegetables washed with the detergent composition are provided.
[0010]
The sucrose fatty acid ester (A) used in the present invention is an ester obtained by reacting sucrose with a fatty acid. As the fatty acid, one having 12 to 18 carbon atoms is suitably used. But it doesn't matter. The degree of esterification of the fatty acid to sucrose is preferably a monoester. Specific examples of sucrose fatty acid esters include, for example, sucrose laurate, sucrose myristate, sucrose palmitate, sucrose stearate, sucrose oleate, sucrose linoleate, and the like. It is an ester.
[0011]
The polyglycerin fatty acid ester (B) used in the present invention is an ester obtained by reacting polyglycerin and a fatty acid. As polyglycerin, decaglycerin, hexaglycerin, tetraglycerin and the like are used. Those having 12 to 18 carbon atoms are preferably used. The esterification degree of the fatty acid to polyglycerin is preferably a monoester. Specific examples of the polyglycerin fatty acid ester include decaglycerin oleate, decaglycerin laurate, decaglycerin stearate, hexaglycerin laurate, and the like, and preferably decaglycerin laurate.
[0012]
Trehalose (C) used in the present invention is a trehalose-type saccharide, which is also known as trehalose and is composed of two molecules of glucose, and is a trehalose-type saccharide linked by reducing groups. It is a compound that can be manufactured using enzymes as raw materials. It is marketed under the trade name “Trehaose”. It is a non-reducing saccharide used as a sweetener.
[0013]
The polylysine (D) used in the present invention is a polyamino acid having L-lysine as a constitutional unit, and is a polymer of lysine which is a basic amino acid. The polymerization degree of polylysine is preferably 8 or more. Specific examples include commercially available polylysine represented by polylysine (manufactured by Chisso).
[0014]
The amount of the sugar cane fatty acid ester (A) and / or polyglycerin fatty acid ester (B) used in the present invention is 10 to 40% by weight, preferably 20 to 30% by weight. If it is less than 10% by weight, the detergency is insufficient, and if it exceeds 40% by weight, the viscosity of the composition rises too much to deteriorate the usability and the stability of the composition. It is preferable to use the component (A) and the component (B) in combination from the viewpoint of the cleaning effect. preferable.
[0015]
The amount of trehalose (C) used in the present invention is 2 to 20% by weight, preferably 3 to 10% by weight. If it is less than 2% by weight, the freshness retention property is insufficient, and if it exceeds 20% by weight, the stability of the composition decreases and the detergency is impaired.
[0016]
The compounding amount of the polylysine used in the present invention is 0.05 to 0.5% by weight, preferably 0.1 to 0.2% by weight. If the content is less than 0.05% by weight, the disinfecting effect is insufficient, and if it exceeds 0.5% by weight, the disinfecting effect is not changed, the color is removed, and the washing effect is reduced.
[0017]
The composition of the present invention is preferably used in the form of an aqueous solution or a solution of a water-soluble organic solvent from the viewpoint of convenience in use. Therefore, when the sum of the components (A), (B), (C) and (D) is less than 100% by weight, water is usually added to make up 100% by weight. In such a detergent, a fragrance, an alcohol, a coloring agent, a viscosity regulator such as propylene glycol, a pH regulator such as sodium hydroxide, a builder, an antifoaming agent, etc. are added as long as the cleaning power and safety are not impaired. You can also.
