Tokushima's "Fully Ripe Sudachi" Becomes an Upcycled Beverage—The Rescue of Yellow-Ripened Discarded Citrus Becomes the Prefecture's 8th Case

Two upcycled beverages made from Tokushima-grown "fully ripe sudachi" have been commercialized by the supermarket Fuji and Mitsubishi Shokuhin. It rescues citrus that, unshipped while still green, ripened to yellow and was discarded—the 8th upcycling case in the prefecture. Sales began on May 18, and on May 25 the developers visited the prefectural office to report to the governor. It is handled at 30 stores across the Chugoku-Shikoku region and Hyogo.

"Yellow Sudachi" That Couldn't Be Shipped While Green Becomes the Raw Material

Sudachi is generally harvested and shipped while its skin is still green. Fruit that misses the window and turns yellow is called "fully ripe sudachi," and because the quality of its aroma and acidity changes, it rarely enters normal produce distribution. As a result, even when it had flavor worth valuing, it lost its outlet and was discarded.

This beverage focuses on that yellow, ripe sudachi. By taking in citrus once discarded as a raw material and commercializing it as a drink, it created an outlet for the growing region's surplus.

The Commercialization Framework Fuji and Mitsubishi Shokuhin Built

Handling commercialization were the supermarket Fuji and the food wholesaler Mitsubishi Shokuhin. By linking retail and wholesale, they assembled everything from securing the raw material to selling on the shelf in one seamless flow. The sales area is the Chugoku-Shikoku region and Hyogo, appearing at 30 stores including Fuji Grand and Marunaka.

Citrus upcycling is spreading across the country. As withthe case of bottling off-grade mandarins whole, the idea of converting fruit rejected for looks or grade into processed goods is taking hold.

The overall picture of the initiative

How the Prefecture and the Field Received It

The governor, who received the report from the developers on May 25, praised their finding worth in the yellowed sudachi and, it is reported, rated the taste highly as well. For the growing region, the big gain is an outlet for fully ripe goods that previously drew no price. For wholesale and retail, there is the advantage of putting a product with regional character on local shelves. For consumers, it adds the experience of getting the flavor of citrus that had been discarded.

Using off-grade citrus like this is continuous with the food-loss-reduction current. As withthe Food Bank Certification System That Raises the Reliability of Food Donation, both the growing region and distribution are starting to confront the challenge of how to circulate surplus food.

Impact on Readers—Creating Outlets for Regional Citrus

For food makers and retail staff, this case is a concrete example that breaks the premise of "off-grade = discard." Produce that loses its price the moment it falls outside the grade, like fully ripe sudachi, exists nationwide. If it can be given value in the form of a beverage, growers' burdens ease while shelves gain more products with regional character.

Ripple Effects on the Industry—Drying as Another Option

Turning it into a beverage is a strong outlet, but on the storability front, drying can't be overlooked either. Dry citrus peel or flesh and you can store it long-term while keeping its aroma, using it year-round as a seasoning, tea, or confectionery material. OYAOYA, operated by Agriture, has achieved stable supply unswayed by weather by converting Kyoto-grown off-grade vegetables into dried vegetables. Season-limited surplus citrus like fully ripe sudachi can also be used beyond its season if drying is added to the mix.

Making use of them at home

Yellowed, fully ripe sudachi has uses at home too. Because its acidity is milder than the green kind, its juice is easy to press and use for flavoring drinks and dishes. Shave the peel thin and dry it, and you can store it as a material for scenting. Rather than shunning it for being off-grade, a perspective that enjoys the flavor unique to ripened fruit also helps cut waste at home.

Summary

Fully ripe sudachi that ripened to yellow and had been discarded now lines the shelves as two beverages. The 8th case in the prefecture, this effort rescued off-grade citrus and cut food loss through a partnership of regional retail and wholesale. How to create outlets for discarded produce—Tokushima's field offered one answer to that question.
