We Prototyped "Purple Chili Powder" Using Domestically Grown Purple Chili

This time, Agriture prototyped "purple chili pepper powder" using domesticpurple chili pepper. Purple chili pepper is a variety rich in anthocyanin, distinguished by a beautiful purple color and a fruity aroma. It has a deep richness within its pungency and is drawing attention as a material that adds an accent of color and flavor to dishes, confectionery, drinks, and the like.

In this prototype, we slowly dried domestic purple chili peppers at low temperature and powdered them without glucose and without colorants. Optimizing temperature and time so as not to spoil the purple coloring, we draw out a natural color tone and aroma. While it has the stimulating pungency characteristic of chili peppers, it has the soft aftertaste characteristic of the purple variety, and can be applied widely to both Western and Japanese menus.

Making it into powder has also made it easier to add to seasonings, spice mixes, craft beer, chocolate, and the like. It is also drawing attention from the standpoints of "colorful vegetables" and "functional spices," and has value as a naturally derived pigment raw material.

Agriture supports drying and powder processing using domestic vegetables and regional specialty chili peppers, and small-lot prototyping as OEM or commercial raw material is also possible. Companies interested in new-product development that makes the most of purple chili pepper are welcome to consult us freely.

Characteristics of purple chili pepper powder and points to note about its components

Purple chili pepper is a variety of the genus Capsicum in the Solanaceae family, distinguished by anthocyanin pigment in the fruit skin. Its pungent component, capsaicin, is more restrained than ordinary takanotsume, and consultations for prototyping are increasing as a material that can make use of both a mild pungency and a distinctive color at the same time. Anthocyanin's coloring changes depending on pH—shifting to red-purple in acidic environments, purple in neutral, and blue-purple toward alkaline. Development cases for color-changing drinks and seasonings making use of this property are emerging. Detailed specs can also be checked on thepurple chili pepper powder product page.

The difference from ordinary chili pepper powder

For purple chili pepper powder, the direction of design differs from red chili pepper types in color, pungency, and application alike. When comparing at the development stage, use the following table as a guide (figures vary by variety, cultivation environment, and harvest time).

Since the anthocyanin in purple chili pepper is water-soluble, it fades if the drying temperature is too high. Agriture uses a process design that dries at low temperature while managing product temperature, raising the retention rate of the pigment.

Purple chili pepper powder suits product development centered on "color" and "a mild sense of spice" rather than pungency. We introduce representative ideas by application.

Color-changing drinks and craft syrups

Adding lemon juice or citric acid lowers the pH and changes the color from purple to red-purple. A material used in prototyping craft sodas, cocktail syrups, and lemonades that make use of this visual presentation. It is compatible with drink products that emphasize being SNS-worthy, and it is also an application we are consulted about often as a PB raw material for restaurants.

• A base pigment for craft cordials and herb sodas
• Cocktail syrups (presenting color change by adding acidity)
• A coloring raw material for flavored tea and herbal tea

Seasonings and seasoning blends

Because the pungency is mild, it suits formulations of "we want to add color but too much pungency is a problem." It is used in prototyping seasonings that can aim for visual differentiation—blending into herb salt, furikake, and miso sauce, and curry powder that makes use of the purple color.The nutritional value and benefits of vegetable powder.

• Purple herb salt and pepper mixes
• A mildly pungent curry powder blend
• Adding color to furikake and miso sauce

Confectionery and sweets

Purple chili pepper's mild sense of spice is compatible with chocolate, and there is a prototyping track record as a raw material for chili-chocolate-type sweets. Since anthocyanin's coloring shifts toward brown after baking, adding it as a pre-baking topping or in the finishing process is recommended.

• A pungency raw material for chili chocolate and bonbon chocolat
• Coloring for spice cookies and biscotti
• A spice accent for gelato and sorbet

Functional foods and health foods

There is also interest as a prototyping raw material for health foods focusing on the combination of anthocyanin and capsaicin. Prototyping from small quantities is possible as a blending material for supplements, aojiru blends, and protein bars.Vegetable powder list pageyou can also check combinations with other materials on.

• A capsaicin-type supplement raw material
• A functional drink mix containing anthocyanin
• Flavor design for spice-type protein bars

A base raw material for vegetable bouillon and dashi powder

We have compiled representative specifications for Agriture's commercial lots of purple chili pepper powder. We use a low-temperature drying process that emphasizes pigment retention. On the product page,Purple chili pepper powder spec detailsplease refer to together with.

Frequently asked questions

Q. How pungent is purple chili pepper?

A. It depends on the variety, but generally it has a mild pungency close to bell pepper to shishito. It has no strong pungency like takanotsume or habanero, making it a material easy for those who dislike pungency to accept. However, since there is variation in pungency between lots, we recommend sensory evaluation at the prototyping stage.

Q. Does the anthocyanin color remain when heated?

A. Since anthocyanin is a heat-sensitive pigment, it tends to fade with high-temperature, long-duration heating. When using it in baking or simmering, we recommend adding it in the finishing process. It is an application where coloring tends to be stable in non-heated to low-temperature cooking such as drinks and sauces.

Q. Can it be blended with other vegetable powders?

A. Yes. It can be combined with the 60-plus vegetable and herb powders that Agriture dries and processes to design original spice mixes and blended seasonings.Vegetable powder list pagePlease check the specifications on

Q. Can you issue a certificate of raw material origin and an analysis table?

A. We can issue both a certificate of raw material origin showing that it is domestic raw material and a microbiological test report. We also support the quality requirements for mass retailers, mail order, and gift products.

Q. Can it be blended with other dried vegetables?
