Additive-free design with vegetable powder | How to choose natural colorants for use as coloring food

Using vegetable powder as a natural coloring lets you put color and flavor into a product with just the ingredient name, without adding food dye or food colorant. The crimson of beet,kabochathe yellow ofSpinach,, the green ofBeet powder, the magenta of purple sweet potato, and more, being able to write "

" or "kabocha powder" in the product's ingredient column is the greatest strength. Uses widen across sweets, confectionery, drinks, noodles, and prepared foods, and adoption is advancing at food makers and D2C brands that want to make additive-free-positioned products.

Agriture processes nearly 100 dried vegetables and vegetable powders by 45°C low-temperature drying, supplying ingredients for confectionery, baking, drink, and noodle OEM. This article compiles how to choose vegetable-powder colorings, the properties and discoloration measures by pigment component, additive-free labeling rules, and blend examples for sweets and confectionery.

The benefits of using vegetable powder as a coloring

For convenience this article calls it "natural coloring," but under the labeling system, vegetable powder is treated as a "coloring food," not a "colorant additive." The options for coloring food fall into three broad categories: ①synthetic colorants, ②naturally derived colorant additives (food dye, food colorant), and ③coloring foods (vegetable powder); which you choose changes the labeling, cost, and positioning.

Additive-free, premium, D2C, commercial OEM

Because vegetable powder is classified as a "coloring food" rather than a colorant additive, it can be listed in the ingredient column by the ingredient name, such as "beet powder." It's positioned to be readily chosen for products that pair it with clean-label and additive-free positioning.

When to choose vegetable powder

• As a coloring food, vegetable powder splits from synthetic colorants and food dye on three points: labeling, positioning, and supply stability. The representative adoption scenes are as follows.
• Working into sweet or baked-goods dough where you want to avoid synthetic colorants
• Wanting to put color and a nutrition angle on a drink or smoothie at once
• Needing a coloring raw material with a stable commercial supply, rather than a food-dye set

Wanting to keep the ingredient label simple to pitch children's products, gifts, and health foods

Vegetable powders by color and their ingredient traitsTomatoThe basics are to work back from the color you want and choose the ingredient. Even the same red finishes as a different thing between beet's magenta-leaning and

's vermilion-leaning, so decide together with the product image.

Combines functional positioning and color

Which color you aim for decides the ingredient and pigment component, and that becomes the starting point for the "discoloration measures" covered in the next section. Reading the table as beet, purple sweet potato, and spinach being color-mobile, and kabocha, carrot, and Kyo-kurenai carrot being relatively stable, makes the blend design easier to organize.

Pigment components and ingredient science (raw-material-level properties)

• Pigments fall broadly into four systems, and their properties at the raw-material stage are the foundation of blend design.
• Betalain (beet): water-soluble. Makes a deep crimson-to-magenta color
• Carotenoid (kabocha, carrot, tomato): between oil-soluble and water-soluble. Lycopene = red-type, β-carotene = orange-type, lutein = yellow-type
• Chlorophyll (spinach): a green pigment with a porphyrin ring. Colors by binding with metal ions

Anthocyanin (purple sweet potato, purple cabbage): a flavonoid-type whose structure changes with pH

• The ingredient traits of Echie Farm's beetGrower
• Recommended ingredient: Echie Farm in Kyotango (environmentally conscious farming using homemade compost)
• Features: betalain. A crimson containing polyphenols
• Cooking suitability: the soaking liquid comes out red too = the color itself can be used in the dish

: soups, marinades, stews, mousse, sauces

Tips for keeping color with natural coloring

The biggest weakness of vegetable-powder coloring is "the color moves easily." Because the color changes with heat, light, pH, and oxygen, you need a design that protects the color at three points: when it's blended, packaging, and storage.

A design that balances best-before date and color retention

Pigment weaknesses often stack up (baking + light / pH + oxygen, etc.), so the shortcut at the prototype stage is to check one factor at a time by varying the conditions.

Agriture's 45°C low-temperature drying

• For vegetable powder used as coloring, the temperature of the drying step changes the vividness of the finished color. Agriture adopts a design based on 45°C low-temperature drying, a processing condition that makes it easier to curb the volatilization and breakdown of pigment components.Standard temperature
• Source: around 45°C (lower than the 70-100°C range of hot-air drying)
• : introduced in Takii Seed Phytorich coverage episode 13 (published October 2025)Where it works
• : the difference shows most with heat-sensitive pigments like chlorophyll, betalain, and anthocyaninAdopting genres

: there are adoption cases in premium confectionery, gifts, and D2C products

• How to decide the blend timing
• OK to work in before baking: kabocha, carrot, tomato (carotenoid types)
• Recommended to top after baking: beet, spinach, purple sweet potato
• Frozen sweets, drinks, creams: with no heat step, every ingredient colors vividly

pH staging in drinks: use citric acid to turn purple cabbage red, baking soda to turn it blue

Rules for labeling additive-free and no-added-colorant"Additive-free" and "no added colorant" run afoul of the Act against Unjustifiable Premiums and Misleading Representations and the Food Labeling Act if you word them wrong. When positioning a product colored with vegetable powder, you need to make the labeling consistent with the actual formulation. For primary sources on the system, you can check the latest color-labeling rules in published materials from the、Consumer Affairs Agency, Food Labeling Divisionand the Ministry of Health, Labour and Welfare, Food Additives

Labeling basics

The labeling of a product using a coloring food is decided by two things: how it's written in the ingredient column and the consistency of the claim wording.

• Ingredient column: list by the ingredient name, such as "beet powder" or "kabocha powder" (don't put it in the colorant slot)
• "No synthetic colorants": can be labeled on the premise of using no synthetic colorants at all
• "No added colorant": only when using none of any colorant additives, including food dye and food colorant
• "Additive-free": specify the target (e.g. "No added colorant, preservative, or flavoring")

Pitfalls to watch for

• Writing "no added colorant" while using food dye or synthetic colorant in part is a violation
• Using "natural" requires a clear definition and grounds (the guidelines call for caution)
• Using the Organic JAS mark presumes obtaining certification (95% or more of the blend being organic raw materials)
• Always do a final check of the actual formulation and the claim wording as a set

Blend amounts and processes by product category

The suited ingredient, blend amount, and process change by product category. We've compiled blend guides for using it as coloring in representative categories.

Blend guides by category

If you want "to add color from a small amount," frozen sweets and cream are the starting point; if you want "to add flavor too without affecting the texture," baked goods, pasta, and bread are. The flour-percentage figures are based on the powder weight (flour, almond flour, etc.) and set as starting values for initial prototyping. Adjustment is needed depending on whether it's baked and on the moisture content.

Patterns prone to failure in baking

• Baking soda in purple-sweet-potato-powder cookies → turns green. Use in a neutral-to-acidic recipe
• Boiling spinach-powder pasta a long time → color drops out. Design for a short boil time
• Beet-powder macarons baked above 180°C → the pink dulls. Keep it to around 150°C
• Displaying a drink in a PET bottle at the storefront → fades with light. Aluminum cans or light-blocking bottles recommended

Understanding the color-fading mechanism from structure

Understanding the reason for fading by pigment at the molecular-structure level makes the blend timing, packaging, and storage rules in product design "a design with reasons" rather than "a hunch." The following is organized based on general food-chemistry knowledge.

How the four systems' fading reactions work

• Betalain (beet): a nitrogen-containing water-soluble pigment. The molecule cleaves easily with heat and fades. Relatively stable in the acidic range; tends to shift in tone under alkali
• Carotenoid (kabocha, carrot, tomato): a fat-soluble conjugated-double-bond pigment. Relatively strong against heat, but isomerizes and oxidatively fades with light and oxygen
• Chlorophyll (spinach, broccoli): the magnesium at the center of the porphyrin ring detaches with acid, changing to pheophytin (the tone darkens). Fades with heat and acid
• Anthocyanin (purple sweet potato, purple cabbage): the structure changes with pH. The tone shifts to red-type in acid, purple-type at neutral, and yellow-type at strong alkali

Where structural understanding pays off in product design

• To keep green in a chlorophyll product → avoid blending strong acid, and design the pH toward neutral
• Color retention in a carotenoid product → light-blocking packaging and an oxygen barrier work well
• Anthocyanin products → adjust to the target color tone with pH design using citric acid and baking soda
• Betalain products → lower the baking temperature, or switch to adding it after baking

Cautions on "additive-free" labeling

When labeling "additive-free" or "no added colorant" on a product using vegetable powder, there are points to watch under the food-labeling system, the Act against Unjustifiable Premiums and Misleading Representations, and Consumer Affairs Agency guidelines. Since the systems and guidelines are amended and updated, checking the latest information before sale is necessary.

Representative patterns that get caught in labeling

• The target of "additive-free" is ambiguous: writing only "additive-free" leaves it unclear what is additive-free, and easily misleads the reader
• Writing additive-free while some additives are included: labeling without ensuring the consistency of the whole formulation carries a risk of violating the Act against Unjustifiable Premiums and Misleading Representations
• Casual use of "natural": under the "Guidelines on Non-Use Labeling of Food Additives" and the like, expressions that mislead call for cautious handling
• A gap between emphasized claims and reality: when a package's emphasized claim diverges from the actual formulation, it can become a target of misleading representation

The basics of safe labeling design

• List the ingredient name accurately in the ingredient column and match the actual formulation to the labeling wording
• When using "additive-free," specify the target (e.g. no synthetic colorant or synthetic preservative)
• Check that claims you want to emphasize are consistent with Consumer Affairs Agency and related guidelines
• Use the consultation desks of local governments and industry bodies to check the label wording before sale

Common failures in vegetable-powder-coloring OEM

We've organized, by stage, the failures that commonly occur in OEM development adopting vegetable powder as coloring. Anticipating them before prototyping reduces the places you stumble.

Five failure patterns

• ① Overexpecting the substitution rate for synthetic colorants: synthetic colorants color vividly in a minute amount, so demanding the same coloring from vegetable powder raises the blend amount and changes the texture and flavor
• ② Deciding on the post-baking color change in one prototype: judging on freshly baked alone without accounting for color change during storage, so fading complaints occur after mass production
• ③ Underestimating the ingredient flavor: even in a blend meant only for color, the vegetable-derived flavor affects the whole product and drifts from the original concept
• ④ Unit mistakes in the blend amount: the definition of "flour" in "% of the flour" differs between makers, so the intended blend amount doesn't get across
• ⑤ Putting off packaging selection: choosing clear packaging without considering light and oxygen resistance, so it fades during storefront display

Prototype design that avoids failure

• At prototyping, vary the blend amount across three levels (0.5x / 1x / 2x) and compare
• Record the color right after production, after one week, and after one month, and use it as the basis for the mass-production storage design
• State the unit definition of the blend amount in the specification (e.g. "% of the flour = % of the total of wheat flour + almond flour")
• Evaluate the packaging's light and oxygen transmission, and if using clear packaging, check whether it has light-blocking UV treatment

Agriture's handled ingredients and processing background

From its base in Kyoto and Kyotango, Agriture keeps a lineup of nearly 100 items of dried vegetables and vegetable powders, with plenty of ingredients chosen for coloring use too. Built on upcycling off-spec vegetables and color retention through 45°C low-temperature drying, it supports the product development of food makers and D2C brands. Consultation is possible from a minimum lot of 100g, and it can respond in stages from small-lot prototyping to mass production.

Agriture ingredients chosen for coloring

• Taniyoshi Farm's dashi dried tomato (Momotaro, Kyotango): lycopene, vermilion
• Takii Seed Phytorich, Kyo-kurenai carrot: lycopene + β-carotene
• Takii Seed Phytorich, Bentenmaru spinach: chlorophyll, deep green
• Dried Kujo green onion (Kyoto): the leaf green survives well, for green coloring in Chinese soups and ramen
• Powders of purple sweet potato, purple cabbage, kabocha, and broccoli

Beet is covered in the ingredient-traits section above, so it's omitted from this list. Since commercial powder-coloring supply is handled on a consultation basis, the basic flow is to tell us the use and then proceed with an individual quote.

Processing background and sourcing setup

• Upcycling of off-spec vegetables: drying and powdering vegetables that don't reach the market because their shape is off-spec. Color and flavor are on par with standard produce, so it can combine with food-loss-reduction positioning
• Contract-farmer partnerships: contracts with specific Kyotango farmers (Echie Farm, Taniyoshi Farm, etc.) allow ingredient sourcing with a fixed variety and origin
• The partnership with Takii Seed Phytorich: has a processing track record of drying and powdering-for-drinks vegetable varieties containing functional components (7 items including Kyo-kurenai carrot, Bentenmaru spinach, and Healthier okra) (coloring use is a separate consultation)
• low-temperature drying at 45°C: the processing conditions introduced in Phytorich coverage episode 13 (published October 2025). A design that curbs the volatilization and breakdown of heat-sensitive pigments

* The ingredients and processing background in this article are organized as "a raw-material lineup that may be applicable to coloring uses." Individual coloring-use OEM proceeds from prototyping according to the product concept.

Information that helps at an OEM consultation
