The growing attention to 'baking soda and citric acid water' and the challenge of palatability
'Baking soda and citric acid water' has been spreading through SNS and word-of-mouth along with rising health and beauty awareness.
In a market survey conducted by our company, respondents interested in baking soda and citric acid water cited their drinking purposes as 'Energy charge' (38.8%), 'Beauty' (37.5%), 'Dietary management' (37.2%), and 'Health maintenance' (29.9%).
On the other hand, there were many comments such as 'It has a strong salty and acidic taste, making it hard to drink' and 'Taste is an issue for continuing it daily.'
Therefore, our company pursued a design that is easier to drink, easier to continue, and easier for nutritional supplementation, while utilizing the refreshing sensation caused by the reaction of baking soda and citric acid.
Harmonizing special baking soda, special citric acid, and special Aojiru with a 'unique technology golden ratio'
'Uwasa no Juso Citric Acid Aojiru® PREMIUM' solves conventional issues by harmonizing the natural effervescence created by combining weakly alkaline 'special baking soda' and acidic 'special citric acid' with 'special Aojiru' in a golden ratio using proprietary technology.
The refreshing sensation of natural carbonated effervescence
By combining food-grade special baking soda and special citric acid, which are safe in terms of quality, a pleasant effervescent sensation spreads the moment you drink it, creating a refreshing time.
Achieving 'ease of drinking' for daily continuation
The salty and acidic taste unique to baking soda and citric acid water, as well as the astringency of green juice, are suppressed by an original formulation. Analysis by a specialized institution (AISSY Inc.) has also proven its high preference with a refreshing aftertaste.
Nutritional design derived from green juice
Using 'barley grass' and 'Suiou' (sweet potato leaves) from Aso, Kumamoto Prefecture as main ingredients, it is further formulated with support ingredients such as NMN and fermented black ginger. It achieves nutritional fortification that goes beyond a mere beverage.
Formulated with 'Special Aojiru' refined through approximately 30 years of research
The blended green juice is a special design that meets everything required of green juice: quality, ease of drinking, and health power.
Uses pesticide-free barley grass, achieving a smooth mouthfeel with a patented manufacturing method
The green juice formulated in this product is a special green juice developed based on health drink research conducted over approximately 30 years. The main ingredients are pesticide-free barley grass from Aso, Kumamoto Prefecture, and the sweet potato leaf brand 'Suiou'.
In addition, the patented 'ultra-fine grinding method' (Patent No. 7290261) achieves a smooth mouthfeel with reduced powderiness.
Formulated with 5 support ingredients alongside barley grass equivalent to approx. 28g of raw vegetables*1
Each serving uses barley grass equivalent to approx. 28g of raw vegetables*1, designed to easily provide vitamins, minerals, and dietary fiber.
Furthermore, 5 support ingredients are formulated as a design to support daily health habits.
NMN
Fermented black ginger (Patent No. 5997822)

*1 Raw vegetables: From the Standard Tables of Food Composition in Japan 2020. Calculated as the weight of the edible portion. Calculated from an example of analysis values.
*2 Analysis results from Japan Food Research Laboratories
*3 Refers to the amount of barley grass used. Calculated assuming the amount of barley grass per serving is 40g for general green juice and 28g for this special green juice.
Overwhelming deliciousness that makes you want to drink it every day
The most emphasized aspect in development was 'flavor balance'.
It suppresses the salty and acidic tastes often felt in conventional baking soda and citric acid water, and also reduces the grassy smell and astringency unique to green juice. It achieves a fruity and fresh taste.
Even in taste evaluations by specialized institutions, it has received praise from perspectives such as 'high aroma', 'fruity', 'easy to drink', 'refreshing feeling', and 'mildness'*3.
Not something you 'force yourself to drink' for health, but 'a cup you want to drink every day'.
You can enjoy the natural effervescence of carbonation and an amazingly light aftertaste.
Over 90% of baking soda and citric acid water drinkers answered 'Delicious'
*Monitor survey conducted by Vitabrid Japan. Proportion of those who regularly drink baking soda and citric acid water who answered 'Delicious' (N=)
