  • Sweetener for desserts and confectionery
  • Cosmetic ingredient in fermentation-positioned skincare lines
  • Hair conditioners and scalp tonics
  • Functional food bars and smoothies

Ingredient profile

Amazake is produced by fermenting cooked rice with koji (Aspergillus oryzae-inoculated rice) for 8 to 12 hours. The enzymatic action of koji breaks down rice starches into glucose, producing natural sweetness without added sugar, and amino acids from rice protein.

Cosmetic amazake extract is produced by water or hydro-alcoholic extraction of amazake, standardized for cosmetic use. The resulting ingredient concentrates the fermentation-derived amino acids and saccharides.

Place in the Koji family. Amazake is a koji-derived liquid preparation. The four-tier structure of Japanese koji ingredients runs: Tane-Koji (種麹, the spore starter culture, typically a Sourcing-only category) → Aspergillus Oryzae Ferment / Koji (the cultivated mold itself) → koji-derived liquids such as Amazake (this entry, the sweet non-alcoholic koji beverage) and Shio Koji (the salt-koji marinade) → major commercial fermented products downstream (miso, soy sauce, sake, mirin, rice vinegar).

OEM applications

As food, amazake is a year-round beverage in contemporary Japan but retains strong winter and seasonal-festival associations. Sakura-season and winter product releases frequently feature amazake.

In cosmetics, amazake extract appears in essences, toners, and sheet masks in fermentation-positioned product lines.

FAQ for OEM buyers

Q. What is amazake?

Amazake (甘酒) is a traditional Japanese sweet, low- or non-alcoholic beverage made by fermenting steamed rice with rice koji (Aspergillus oryzae cultivated on rice) for approximately 8–12 hours at around 55–60 °C. Koji-derived amylases hydrolyze rice starch into glucose, giving natural sweetness without added sugar. A separate variant (sake-kasu amazake) is reconstituted from sake lees and contains low alcohol (typically up to a few percent); the koji-only variant is non-alcoholic and is the traditional 'children's safe' product.

Q. Is amazake genuinely 'nomu tenteki' (drinkable IV drip)?

The 'drinkable IV drip' nickname is a marketing phrase in Japan referring to amazake's natural composition: glucose, B-group vitamins (B1, B2, B6, niacin), free amino acids, and oligosaccharides. The phrase is not a registered health claim and has no regulatory basis — Japanese consumer-affairs guidance requires functional claims to be substantiated under Tokuho or FFC. Amazake's nutrient density is real, but 'IV drip' is metaphor, not approved medical positioning.

Q. Are there FFC-notified amazake products in Japan?

Yes. The Hakkaisan Brewery 'Kōji dake de tsukutta Amasake' product is the first koji-only amazake notified under Japan's Foods with Function Claims (FFC) system, carrying claims based on Aspergillus oryzae HJ1-derived components and koji-derived glucosylceramide (claims relate to skin moisture support per the registered notification). Several other FFC-notified amazake products from major Japanese sake breweries follow, with varying claim wording.

Q. Is amazake suitable for children and pregnant consumers?

Koji-only (non-alcoholic) amazake — typically labelled '麹甘酒' or 'ノンアルコール甘酒' — contains no added alcohol and is widely consumed by children and pregnant women in Japan. Sake-kasu (sake-lees) amazake contains residual alcohol from the sake lees (often around 1–2%) and is not appropriate for these consumers. Always read the label: under Japan's Liquor Tax Act, beverages containing ≥1% ABV are classified as alcoholic.
