It is used as a health food that can be acquired.
　青汁は、野菜不足を補う目的で利用されるほか、便秘解消、生活習慣病の解消、美肌・美容、ダイエット、がん予防、皮膚疾患の予防や解消、アンチエイジング、血液さらさら化、アレルギー予防・免疫力の向上などの作用効果を期待した利用も広がっており、昨今の健康志向の高まりとともに需要が伸びている。 Aojiru is used for the purpose of supplementing the lack of vegetables, constipation relief, elimination of lifestyle-related diseases, beautiful skin and beauty, diet, cancer prevention, prevention and elimination of skin diseases, anti-aging, blood smoothing, allergy prevention.・It is also being used in hopes of improving immunity and other effects, and demand is growing along with the recent rise in health consciousness.
　一方で、青汁の原料には特有の臭みがあるため、継続的に摂取することをしばしば困難にする。このため、青汁の臭みを抑制するために、組成上の工夫や製法上の工夫がなされている。例えば、組成上の工夫として、特許文献１に、ケール青汁に大豆加工品を添加することが記載されており、特許文献２に、ケール粉末にココアパウダーを所定量配合することが記載されている。また、製法上の工夫として、特許文献３に、ケール成分を含有する飲料の製造方法においてケール成分含有液に酢酸菌を接触させることが記載されており、特許文献４に、容器詰青汁飲料を製造する方法において、青汁に金属イオンを添加し、青汁のｐＨを調整し、青汁を直接殺菌することが記載されている。 On the other hand, the ingredients of green juice have a unique smell, which often makes it difficult to consume continuously. For this reason, in order to suppress the odor of green juice, efforts have been made to improve its composition and manufacturing method. For example, Patent Document 1 describes adding a processed soybean product to kale green juice as a compositional device, and Patent Document 2 describes adding a predetermined amount of cocoa powder to kale powder. there is In addition, as a device for the production method, Patent Document 3 describes contacting acetic acid bacteria with a kale component-containing liquid in a method for producing a beverage containing a kale component, and Patent Document 4 describes a packaged green juice beverage. In the method for producing, it is described that metal ions are added to the green juice, the pH of the green juice is adjusted, and the green juice is directly sterilized.

The obtained granular powder was stored in a glass bottle at 50° C. for 2 days, and then 3 g of the granular powder (corresponding to 1 g of component (A)) was dispersed in 100 mL at room temperature to prepare a sample solution. The odor of the sample solution was sensory evaluated by 6 trained panelists. Specifically, the degree of unpleasant grassy odor peculiar to (A) component was evaluated by 10-step VAS evaluation (10 points: strong unpleasant smell, 1 point: no unpleasant smell), and 6 people The panelists' ratings were averaged to give an average score. When the average score of the sample solution prepared from the powdered beverage of Comparative Example 1 is set to 100, the relative value of the average score of the sample solution prepared from the powdered beverage of each Comparative Example and each Example is rounded off to the first decimal place. It was calculated as an evaluation value of "odor". It can be evaluated that the smaller the calculated "odor" evaluation value, the higher the odor suppressing effect. Table 1 shows the results obtained.
