Kale powder
Domestic kale powder is a commercial powder raw material made by low-temperature drying kale—a superfood rich in vitamin K, vitamin C, beta-carotene, and dietary fiber—and processing it through grinding in-house within Kyoto Prefecture. Without glucose, coloring, or antioxidants, it concentrates kale's inherent nutritional value and deep green into a powder. It's a raw material frequently consulted about for food development that wants to appeal to both nutritional value and color at once—green drinks, green smoothies, health foods, green powder blends. We also handle prototyping from 1kg of fresh leaf.For consultations on dried vegetable and powder OEM herePlease let us know your intended use and desired specifications from

Three points of care in Agriture's kale powder
01 Low-temperature drying concentrates nutritional value and green into a powder
Because the vitamin C and beta-carotene in kale are heat-sensitive, high-temperature drying causes large nutritional losses. Agriture uses hot-air drying that keeps product temperature in a low-temperature range, with a process design that retains a nutritional profile close to fresh leaf and a deep green even after grinding.Vegetable & herb powder listYou can also consult us about blending with other materials from

Characteristics of commercial kale powder
Concentrating a superfood's nutritional value
Kale is rich in vitamin K, vitamin C, beta-carotene, calcium, and dietary fiber. Thanks to the concentration effect of powdering, it's a raw material that lets you take in nutrients efficiently in small amounts.
A deep green color
Low-temperature drying and short-time grinding suppress chlorophyll fading, maintaining kale's distinctive deep green even after powdering. It visually conveys the "healthy look" of green drinks and smoothies.
Green-drink-grade quality control
We perform hygiene management at a grade usable as a raw material for health foods and green drinks. We also handle issuing specification sheets and microbial test reports, meeting the quality requirements of health-food manufacturers.
Zero additives, no coloring
Glucose, dextrin, antioxidants, and coloring are all unused. A spec that pairs well with PB development of green drinks promoting "100% domestic kale."
Flexible for blend design too
We also handle pre-blending with young barley grass, moringa, ashitaba, dried fruit powder, and the like. We can also discuss raw material design for superfood mixes and green powder blends.

Commitments to variety, grower, and growing region
The raw material used in Agriture's kale powder is domestic kale sourced directly from partner farms in Japan. Because bitterness intensity and nutritional profile differ by cultivar, cultivar selection to match the use is the key to quality.
BRAND
Variety: Kale (Brassica of the Brassicaceae family). A superfood rich in vitamin K, vitamin C, beta-carotene, calcium, and dietary fiber. Flavor varies by cultivar—curly kale (stronger bitterness) or Tuscan kale (milder), for example.
PRODUCER
Producer: Partnering with domestic kale-growing farmers, we source from producers who can ensure green-drink-grade quality.
REGION
Growing region: We procure raw material from producing regions with climate conditions suited to kale cultivation, centered on Japan's warm areas.
CULTIVATION
Cultivation method: With managed cultivation that limits pesticide use, we've built a record-keeping system that can also meet the raw material origin certification health-food manufacturers require.
Low-temperature drying technology and quality control
Kale's nutritional value and pigment components are heat-sensitive, and high-temperature drying advances both vitamin C loss and chlorophyll browning at once. Agriture uses hot-air drying that keeps product temperature in a low-temperature range, designed to let out only moisture while retaining both nutritional value and green. Grinding is done immediately after drying to minimize oxidation.
Manufacturing is done at our own processing plant in Kyoto Prefecture, with integrated management from raw-material acceptance inspection to shipment. It is filled after passing through a foreign-matter removal process, and for OEM projects we issue necessary documents such as specification sheets, raw-material origin certificates, and microbiological test reports, upon consultation for each project.
TIPS | Kale powder know-how
Kale's bitterness varies greatly with cultivar and maturity. When prioritizing ease of drinking as a green drink, select a mild cultivar; when foregrounding health benefits, choose a cultivar that includes the bitter components. Agriture can prepare multiple samples with differing bitterness at the prototyping stage.

Points on commercial use and storage
Kale powder needs no rehydration—use it as is, dissolved in water, milk, or a smoothie. When drinking it as a green drink, shaking it in a shaker or blending it makes the mouthfeel smooth. When kneading it into dough, dry-blend it with the flour ingredients in advance before adding water for even mixing.
For storage, airtight storage away from light, heat, and humidity is best. Chlorophyll fades easily under light in particular, so we recommend storing it in light-blocking packaging. After opening, use it up promptly, or reduce air contact with nitrogen flushing or a zip bag to keep color and nutritional value longer.
