Description

本発明は、脂肪酸組成中の飽和脂肪酸が1重量%以上15重量%以下および36℃付近における電気伝導度が35分後に0.05mS/m以上1.0mS/m以下であることを特徴とする油相が5重量%以上35重量%以下である油中水型乳化組成物に関する。本発明は、風味発現性が良好であり、微生物育成が抑制され、また、その製造方法が簡便な油中水型乳化組成物を提供することができる。 The present invention is characterized in that the saturated fatty acid in the fatty acid composition is 1% by weight or more and 15% by weight or less, and the electrical conductivity at around 36 ° C. is 0.05 mS / m or more and 1.0 mS / m or less after 35 minutes. The present invention relates to a water-in-oil emulsified composition having an oil phase of 5% by weight or more and 35% by weight or less. INDUSTRIAL APPLICABILITY The present invention can provide a water-in-oil emulsified composition having good flavor expression, suppressing microbial growth, and having a simple production method.

従来、低脂肪スプレッドを製造するために多種の方法が取られてきた。例えば、酸化デンプン、ヒドロキシプロピルデンプンのいずれか1種以上およびゼラチンを用いる方法(特許文献1)95乃至86重量%の水性相と少なくとも5のN20値を有する5乃至14重量%の連続脂肪相とを含む方法(特許文献2)、30重量%より少ない脂肪含量を有し、タン白又はハイドロコロイド又はこれらの混合物を含有する水性相を含む連続脂肪相から成る食用可塑性分散体であって、水性相を構成する組成物は35℃の温度および1000秒-1の剪断速度で400cps(400mPa・s)より少ない粘度を有し、そしてアミノ酸残基含量は水性相の重量基準で計算して200ppmより少なくする方法(特許文献3)、10〜35重量%の連続脂肪相および90〜65重量%の分散水性相を含む、35重量%より少ない脂肪を含有するスプレッドであって、水性相を構成する組成物は17090秒-1の剪断速度および5℃の温度で少なくとも20mPa・sの粘度を有する方法(特許文献4)、解乳化特性の異なる2種類以上の乳化組成物を調製し、これらを混合する方法(特許文献5)が開示されている。 Traditionally, various methods have been used to produce low-fat spreads. For example, a method using any one or more of oxidized starch and hydroxypropyl starch and gelatin (Patent Document 1) 95 to 86% by weight aqueous phase and 5 to 14% by weight continuous fatty phase having an N 20 value of at least 5. (Patent Document 2), an edible plastic dispersion comprising a continuous fat phase having a fat content of less than 30% by weight and containing an aqueous phase containing protein or hydrocolloid or a mixture thereof, which is aqueous. The compositions constituting the phase have a viscosity less than 400 cps (400 mPa · s) at a temperature of 35 ° C. and a shear rate of 1000 seconds-1 and the amino acid residue content is less than 200 ppm calculated on the weight basis of the aqueous phase. A method of reducing (Patent Document 3), a spread containing less than 35% by weight of fat, comprising 10 to 35% by weight of continuous fat phase and 90 to 65% by weight of dispersed aqueous phase, constituting the aqueous phase. The composition has a shear rate of 17090 seconds-1 and a viscosity of at least 20 mPa · s at a temperature of 5 ° C. (Patent Document 4), two or more emulsifying compositions having different demulsification characteristics are prepared and mixed. (Patent Document 5) is disclosed.

しかしながら、従来の方法では、得られた低脂肪スプレッドの風味発現性と微生物育成の抑制を両立することは難しく、また、その製造方法も必ずしも簡便なものではなかった。
特許文献1では、酸化デンプン、ヒドロキシプロピルデンプンのいずれか1種以上およびゼラチンを用いて低脂肪スプレッドを調製し、風味発現性および微生物育成を評価しているが、油中水型乳化組成物の水相に着目したものであり、油相についての技術の開示はない。さらに油相含量、飽和脂肪酸量を物性値の電気伝導度と関連付けられたことは今までなく、油相含量、飽和脂肪酸量、および電気伝導度値を特定の範囲にすることにより、風味発現性と微生物育成の抑制の両立が成されることは知られていなかった。電気伝導度はスプレッド(油中水型乳化組成物)の解乳化(乳化状態が壊れる状態)の程度の指標となり、特許文献2〜5では、電気伝導度を微生物育成の抑制や風味発現性の指標として用いている。特許文献2〜4では、微生物育成の抑制や転相抑制の指標として10℃や15℃でスプレッドそのものの電気伝導度を測定しており、その値は低ければ低いほど望ましいものであった。また、風味発現性についての開示はない。特許文献5は、口中温度を模した測定により風味発現性の指標としてスプレッドを水中に添加した電気伝導度を測定しており、その値は高いほど望ましいものであった。また、微生物育成の抑制についての開示はない。
However, with the conventional method, it is difficult to achieve both the flavor expression of the obtained low-fat spread and the suppression of microbial growth, and the production method thereof is not always simple.
In Patent Document 1, a low-fat spread is prepared using one or more of oxidized starch and hydroxypropyl starch and gelatin, and flavor expression and microbial growth are evaluated. However, a water-in-oil emulsified composition is used. It focuses on the aqueous phase and does not disclose the technology for the oil phase. Furthermore, the oil phase content and the amount of saturated fatty acids have never been associated with the electrical conductivity of physical properties, and by setting the oil phase content, the amount of saturated fatty acids, and the electrical conductivity values within a specific range, flavor expression is exhibited. It was not known that both the suppression of microbial growth and the suppression of microbial growth were achieved. The electric conductivity is an index of the degree of emulsification (state in which the emulsified state is broken) of the spread (water-in-oil emulsified composition). It is used as an index. In Patent Documents 2 to 4, the electrical conductivity of the spread itself is measured at 10 ° C. or 15 ° C. as an index for suppressing microbial growth and phase inversion, and the lower the value, the more desirable it is. In addition, there is no disclosure regarding flavor expression. Patent Document 5 measures the electrical conductivity in which a spread is added to water as an index of flavor expression by measuring the temperature in the mouth, and the higher the value, the more desirable it is. In addition, there is no disclosure regarding the suppression of microbial growth.

油脂原料は、大豆油、ナタネ油、大豆硬化油(融点41℃)を組み合わせて表1に示す油相量、飽和脂肪酸量、トランス脂肪酸量に調整し、これに油系原料(乳化剤およびβ‐カロチン)を添加し、60℃に保持しながら撹拌し、乳化剤およびβ‐カロチンを溶解させて油相を調製した。次いで、60〜80℃の温水に水系原料を添加、混合して溶解して水相とした。油相に水相を撹拌しながら添加して乳化し、さらに香料を加えて混合した。得られた乳化物を90℃まで昇温させ殺菌した後40℃まで冷却し、コンビネーターを急冷可塑化機として用い、冷却勾配および回転数を調整して表1に示す電気伝導度に調整し、15℃に冷却、練圧することによりスプレッド5種(実施例品1〜3、比較例品1、2)を得た。 The oil-based raw materials (emulsifier and β-) are prepared by combining soybean oil, rapeseed oil, and hydrogenated soybean oil (melting point 41 ° C.) to adjust the oil phase amount, saturated fatty acid amount, and trans fatty acid amount shown in Table 1. (Carotene) was added, and the mixture was stirred while maintaining at 60 ° C. to dissolve the emulsifier and β-carotene to prepare an oil phase. Next, an aqueous raw material was added to warm water at 60 to 80 ° C., mixed and dissolved to prepare an aqueous phase. The aqueous phase was added to the oil phase with stirring to emulsify, and a fragrance was further added and mixed. The obtained emulsion was heated to 90 ° C., sterilized, cooled to 40 ° C., and a combinator was used as a quenching plasticizer to adjust the cooling gradient and rotation speed to the electrical conductivity shown in Table 1. , Cooled to 15 ° C. and kneaded to obtain 5 types of spreads (Examples 1 to 3 and Comparative Examples 1 and 2).

得られたスプレッドを容器に充填して5℃に保存した後、風味発現性および微生物育成について評価した。風味発現性については、官能評価の訓練を積んだ専門パネル10名によって5点法で実施した。微生物育成は、表面にカビ培養液を散布したスプレッドを25℃30日間保存し、表面(8.5×11cm)のカビ数を計測することにより実施した。結果は、次の評価基準に基づいて評価した。さらに、総合評価として上記指標を総合的に判断した結果を5点法で実施した。 The obtained spread was filled in a container and stored at 5 ° C., and then the flavor expression and microbial growth were evaluated. Flavor expression was carried out by a 5-point method by 10 specialized panels trained in sensory evaluation. Microorganism growth was carried out by storing a spread sprayed with a mold culture solution on the surface at 25 ° C. for 30 days and measuring the number of molds on the surface (8.5 × 11 cm). The results were evaluated based on the following evaluation criteria. Furthermore, as a comprehensive evaluation, the result of comprehensively judging the above indicators was carried out by the 5-point method.

結果を表2に示した。表2から明らかなように、実施例品1〜3は、風味発現性が良好で、微生物育成が抑制されていた。一方、実施例品より油相の含有量が低い比較例品1のスプレッドは転相してしまい、含有量が高い比較例品2はオイルオフを生じてしまい、風味発現性に劣っていた。 The results are shown in Table 2. As is clear from Table 2, Examples 1 to 3 had good flavor expression and suppressed microbial growth. On the other hand, the spread of Comparative Example Product 1 having a lower oil phase content than that of the Example product was phase-inverted, and Comparative Example Product 2 having a higher oil phase caused oil off and was inferior in flavor development.
