従来の風味改善方法は、青臭みだけでなく、大豆由来の良好な風味も抑制してしまう場合があった。また、製造工程中に加熱処理が含まれる場合、依然として、製造した大豆飲食物にざらつき感が残り、風味が低下してしまう場合があった。   Conventional flavor improving methods sometimes suppress not only the blue odor but also the good flavor derived from soybeans. In addition, when heat treatment is included in the production process, the produced soybean food or drink still has a rough feeling, and the flavor may be lowered.

そこで、本発明は、大豆由来の良好な風味を保持しつつ、大豆の青臭みを抑制し、風味を改善する手段を提供すること、及び、加熱処理などにより生じる大豆飲食物のざらつき感を抑制すること、を主な目的とする。   Therefore, the present invention provides a means for suppressing the blue odor of soybean and improving the flavor while maintaining a good flavor derived from soybean, and suppresses the rough feeling of soybean food and drink caused by heat treatment, etc. The main purpose is to do.

本発明者らは、分岐構造を有する3〜4糖類を含有する糖組成物を大豆飲食物に用いることにより、大豆の青臭みを抑制することを新規に見出した。また、それらの糖組成物には、加熱処理によって生じる大豆飲食物のざらつき感(口当たりの悪さ)の発生を抑制することを新規に見出した。   The present inventors have newly found out that the blue odor of soybean is suppressed by using a sugar composition containing a 3-4 saccharide having a branched structure in soybean food and drink. Moreover, it discovered newly that those sugar compositions suppress generation | occurrence | production of the rough feeling (bad taste) of the soybean food and drink which arises by heat processing.

そこで、本発明では、それらの糖組成物を有効成分とする、大豆飲食物の風味改善剤を提供する。   Therefore, in the present invention, there is provided a flavor improving agent for soybean foods and drinks containing these sugar compositions as active ingredients.

Moreover, generation | occurrence | production of the rough feeling of soybean food and drink can be suppressed even when heat processing are given during a manufacturing process. That is, the sugar composition according to the present invention can be used for the purpose of improving the flavor of soybean food and drink.

加えて、この糖組成物を用いることには、以下のような利点がある。   In addition, the use of this sugar composition has the following advantages.

これらの糖組成物は、低甘味であるため、大豆飲食物全体の風味に対してあまり影響を与えない。また、これらの糖組成物は、甘味質に優れており、砂糖など他の甘味成分との相性も良好である。従って、大豆由来の良好な風味(青臭みなど以外の風味)を保持できる。   Since these sugar compositions have a low sweetness, they do not significantly affect the flavor of the whole soybean food and drink. In addition, these sugar compositions are excellent in sweetness and have good compatibility with other sweet ingredients such as sugar. Therefore, a good flavor derived from soybeans (flavor other than blue odor) can be maintained.

この糖組成物を飲食物に加えても、健康上、特に影響はなく、緩下作用(下痢)などもほとんどない。従って、この組成物は、従来の方法などと比較して、安全性が高い。   Even if this sugar composition is added to foods and drinks, there is no particular effect on health and there is almost no laxative action (diarrhea). Therefore, this composition is safer than conventional methods.

大豆飲食物の製造工程においてこれらの糖組成物を加えることにより、比較的簡易に、風味を改善できるため、特別な設備改良や工程改良を行う必要がない。また、この組成物は、比較的安価に入手できる。従って、この組成物を用いることにより、大豆飲食物の製造コストを抑制できる。   By adding these sugar compositions in the production process of soybean foods and beverages, the flavor can be improved relatively easily, so there is no need for special equipment improvements or process improvements. Moreover, this composition can be obtained comparatively cheaply. Therefore, the production cost of soybean food and drink can be suppressed by using this composition.

本発明に係る糖組成物を用いることにより、大豆飲食物の風味を改善できる。即ち、大豆由来の良好な風味を保持しつつ、大豆の青臭みを抑制でき、また、製造工程中に加熱処理が施される場合でも、大豆飲食物のざらつき感の発生を抑制できる。   By using the sugar composition according to the present invention, the flavor of soy food and drink can be improved. That is, while maintaining a good flavor derived from soybeans, it is possible to suppress the blue odor of soybeans, and even when heat treatment is performed during the production process, it is possible to suppress the occurrence of a rough feeling in soybean foods and drinks.

The outline of the experimental procedure is as follows.
(1) First, a prototype of prepared soy milk was produced in the same procedure as in Example 2. As the sugar composition, a sugar composition containing 50% of 3-4 saccharides having a branched structure (hereinafter referred to as “sugar composition prototype”) was used (the same thing is used in the following examples). Using).
(2) Next, pretreatment by a solid phase micro (hereinafter referred to as SPME: Solid Phase Micro Extraction) method was performed. The SPME method was performed according to the method described in the method of Suratman et al. (Non-patent Document 3). First, 10 ml of prepared soymilk was placed in a 20 ml vial (supplico), and 20 ppm of nocyclohexanone (internal standard substance) was added. Next, the vial was sealed with a septum cap (manufactured by SUPELCO, Teflon sealed, “Teflon” is a registered trademark), and preheated at 60 ° C. for 30 minutes. Next, SPME fiber was put into the head space portion of the vial for 30 minutes to extract volatile components. As the SPME fiber, a Carboxen / PDMS (polydimethylcycloxan) fiber (SUPELCO) having a thickness of 75 μm was used.
(3) Next, analysis was performed using a gas chromatograph mass spectrometer. SPME fiber (containing the extracted component) was put into the sample inlet of the analyzer, and the components contained in the prepared soymilk were quantified based on the peak area and peak height of the internal standard substance. As the gas chromatograph mass spectrometer, GCMS-GP5050A (manufactured by Shimadzu Corporation) was used. As the capillary column, TC-FFAP (manufactured by GL Science Co., Ltd.) was used. Helium gas was used as the carrier gas, and the flow rate was set to 1 ml / min. The temperature of the sample inlet was set to 250 ° C., and the column temperature was raised to 200 ° C. at 5 ° C./min after 2 minutes at 40 ° C. and maintained at 200 ° C. for 4 minutes. The extraction component was introduced into the capillary column by a spiritless method. Mass spectrometry was performed in the range of 30 to 400 m / z.

結果を図1に示す。図1に示す通り、豆乳に糖組成物試作品を添加して調製した場合、無添加の場合や砂糖を添加して調製した場合と比較して、脂質カルボニル化合物(1−ペンタナール、1−ヘキサナール、2−ヘプテナールなど)が顕著に減少した。
これらの化合物は、大豆由来の青臭さの原因物質であることが明らかになっている(非特許文献4参照)。
従って、本実験結果は、分岐構造を有する3〜4糖類を含有する糖組成物には、大豆由来の青臭さを抑制する作用があることを強く示唆する。
The results are shown in FIG. As shown in FIG. 1, the lipid carbonyl compounds (1-pentanal, 1-hexanal) are prepared by adding a sugar composition prototype to soy milk, as compared with the case where no sugar is added or when sugar is added. , 2-heptenal, etc.) decreased significantly.
These compounds have been found to be causative substances of soybean-derived blue odor (see Non-Patent Document 4).
Therefore, this experimental result strongly suggests that the sugar composition containing 3-4 saccharides having a branched structure has an action of suppressing the blue odor derived from soybeans.

実施例4では、豆乳飲料の試作品を作製し、試飲した。   In Example 4, a prototype of a soy milk drink was prepared and sampled.

まず、500mlの水に、乳酸カルシウム35g、グルコン酸カルシウム10g、塩化カルシウム15gを溶解させた。次に、市販の有機豆乳1.5kgに、この溶液を、撹拌しながら少しずつ加えた後、糖組成物試作品75gを加えた。次に、この有機豆乳のタンパク質濃度が4重量%になるように水分調整した後、ホモジナイザーで均質化した。次に、均質化した有機豆乳を、121℃、5分間オートクレーブで処理した後、流水で冷却し、冷蔵庫で一昼夜保管した。なお、対照では、糖組成物試作品の代わりに砂糖を用いた。   First, 35 g of calcium lactate, 10 g of calcium gluconate, and 15 g of calcium chloride were dissolved in 500 ml of water. Next, after adding this solution little by little to 1.5 kg of commercially available organic soymilk, 75 g of a sugar composition prototype was added. Next, the water content was adjusted so that the protein concentration of the organic soymilk would be 4% by weight, and then homogenized with a homogenizer. Next, the homogenized organic soymilk was treated with an autoclave at 121 ° C. for 5 minutes, cooled with running water, and stored in a refrigerator all day and night. In the control, sugar was used instead of the sugar composition prototype.

上記手順で作製した豆乳飲料の試作品を試飲したところ、対照の豆乳飲料と比較して、青臭さが少なく、舌触りも滑らかで、ざらざら感も少なかった。   When the prototype of the soy milk beverage produced by the above procedure was sampled, it had less blue odor, smooth texture and less rough feeling than the control soy milk beverage.

実施例5では、豆乳プリンを作製し、試食した。   In Example 5, soymilk pudding was prepared and sampled.

まず、牛乳700gと豆乳650gを入れた容器に、全卵750gを混ぜながら徐々に加え、均一化させた。次に、糖組成物試作品300g、砂糖300gを加え、再度、均一化させた。次に、均一化した調製物を、メッシュで3回裏ごしした後、カップに120gずつ充填した。次に、このカップを蒸し器に入れ、7分間、加熱処理した後、室温まで冷却させ、冷蔵庫で一昼夜保管した。なお、対照では、糖組成物試作品の代わりに砂糖を用いた。   First, 750 g of whole eggs were gradually added to a container containing 700 g of milk and 650 g of soy milk while being homogenized. Next, 300 g of a sugar composition prototype and 300 g of sugar were added and homogenized again. Next, the homogenized preparation was lined with a mesh three times, and then 120 g was filled into the cup. Next, this cup was put into a steamer, heated for 7 minutes, cooled to room temperature, and stored in a refrigerator all day and night. In the control, sugar was used instead of the sugar composition prototype.

上記手順で作製した豆乳プリンの試作品を試食したところ、対照の豆乳プリンと比較して、青臭さが少なく、舌触りも滑らかで、ざらざら感も少なかった。   When the prototype of the soy milk pudding produced by the above procedure was sampled, it had less blue odor, smooth texture and less rough feeling than the control soy milk pudding.

本発明に係る糖組成物を用いることにより、大豆飲食物の風味を改善できる。即ち、本発明に係る糖組成物は、風味改善剤として、適用可能である。本発明に係る風味改善剤は、大豆由来の良好な風味を損なわずに、青臭みなどの風味を抑制できるという利点がある。また、加熱処理(加熱殺菌)工程で生じるざらつき感も抑制できるため、例えば、豆腐、豆乳、調製豆乳、豆乳飲料などにも適用可能である。   By using the sugar composition according to the present invention, the flavor of soy food and drink can be improved. That is, the sugar composition according to the present invention is applicable as a flavor improving agent. The flavor improving agent according to the present invention has an advantage that flavor such as blue odor can be suppressed without impairing the good soybean-derived flavor. Moreover, since the rough feeling which arises in a heat processing (heat sterilization) process can also be suppressed, it is applicable also to tofu, soy milk, prepared soy milk, a soy milk drink, etc., for example.
