Dried watermelon
Product overview of dried watermelon (Nagano-grown)
Nagano-grown watermelon nurtured by the temperature difference unique to high-altitude regions is lavishly sliced and slowly dried at low temperature. By carefully finishing this fruit with its high moisture content, it becomes a unique dried fruit that concentrates the watermelon’s inherent juicy sweetness and a faint green aroma.
Without using any sugar or additives, it seals in the natural sweetness and aroma as they are, making it ideal for confectionery and tea-making uses that seek the flavor of the ingredient itself. With its gentle flavor and visual impact, it is also popular as a gift or topping.
Three points of commitment for dried watermelon
01 Grown by partner farmers in Nagano Prefecture
Uses Nagano-grown watermelon in which sweetness is stored by the day-night temperature difference due to altitude. Sourced from partner farmers and processed all at once in the July–August peak season, it is crafted into a raw material with a sense of season.
02 The difficult drying of watermelon, with proprietary technology
Watermelon has an overwhelmingly high moisture content, making it a fruit that’s difficult to dry-process. At Agriture, with proprietary low-temperature, long-time drying know-how, we finish it into dried watermelon that retains the ingredient’s inherent sweetness and aroma.
03 Sugar-free and additive-free, for a natural finish
Without using any sugars, additives, or colorants, it retains the watermelon’s inherent pale red color and green aroma as they are. Because the market circulation volume is small, it also becomes a centerpiece material for product development where you want to achieve differentiation.

Characteristics of commercial dried watermelon
Uses watermelon sourced from partner farmers within Nagano Prefecture. The temperature difference due to altitude draws out the sweetness, letting a fresh, juicy flavor ride onto the raw material.
The slice shape including the red flesh and rind portion has big impact from the red-and-green contrast. It is a shape you can use as-is in products with strong visual appeal.
Dried watermelon, with little market circulation, has rarity itself as a differentiation element. It is also valued as a centerpiece material for summer-limited or summer-gift plans.
Fresh watermelon has low keeping quality and is a hard-to-handle ingredient for commercial uses, but drying processing enables 6 months of room-temperature storage. It can also be deployed in product plans for seasons other than summer.
Supportable from a minimum of 10 bags / 100 g units, flexibly accommodating prototyping by craft makers too. You can expand in stages from package testing.
Powder processing is also possible. It can be deployed as a material evoking a summery feel—for drink bases, sauces, and sweets ingredients.

Commitments to variety, grower, and growing region
Cultivar:Uses watermelon cultivated within Nagano Prefecture. Selecting varieties suited to the growing region’s climate, we source ones that combine sweetness and juiciness.
Producer:In cooperation with partner farmers within Nagano Prefecture. Having the fully ripe fruit delivered to the processing base right after harvest, we carry out drying processing while it is still highly fresh.
Production area:Nagano Prefecture. It is a growing region where, in an environment where the temperature difference unique to high-altitude regions easily draws out sweetness, the watermelon’s flavor can be adjusted from the raw-material level.
Cultivation method:Watermelon grown by partner farmers’ open-field and greenhouse cultivation is harvested to match the seasonal peak. In the July–August height of the season, it is sent to the processing line all at once.
Dried watermelon finished by low-temperature, long-time drying
Watermelon has a very high moisture content, making it a prime example of a fruit that’s difficult to dry-process. At Agriture, with proprietary low-temperature, long-time drying technology, we give it a distinctive finish that draws out the watermelon’s inherent pale red color, green aroma, and a sweetness that retains juiciness. It is characterized by a light, crisp texture and the watermelon-specific aroma that spreads afterward.
Watermelon has a higher moisture ratio than other fruits, and is a material with a low production yield for dried products. For that reason, its market circulation volume is small, making it suited to product plans with more originality than other dried fruits. During storage, sealing it away from humidity keeps the crisp texture for a long time.

Yakuzen-style effects (in the case of fresh watermelon)
What we introduce here is the yakuzen way of thinking regarding fresh watermelon before drying processing. It does not guarantee the effects of the dried product itself; please use it as reference information for understanding the properties as a raw material.
Watermelon is a fruit representative of summer, said to have the action of removing excess heat from the body and moistening a parched throat. Beyond eating it chilled as is, it is also used as a refreshing material on hot days by processing it into juice or smoothies.
In the yakuzen way of thinking, for a state where heat is trapped in the body from summer heat, it is considered good to incorporate ingredients that have a heat-cooling property. Watermelon is a representative of that, and is also cherished as an ingredient that gives moisture to the body.
Even when dried, dried watermelon is easy to make use of in product design with its ingredient-derived story, and it is a raw material that goes well with yakuzen and seasonal appeal.
