What Are Dried Tomatoes? A Basic Guide to Types, Flavor and Uses
Summary of this article
Dried tomatoes are a processed food made by drying ripe tomatoes, concentrated to about 10–15% of their fresh weight with concentrated glutamic acid. This article systematically explains, for beginners, the characteristics of the three types—salted, oil-packed, and unsalted/oil-free dried—as well as nutrition such as lycopene, the basics of rehydration, how to make an oil pack, storage methods, quality differences from low-temperature drying, and using high-sugar tomato varieties like Aiko and Frutica.
Dried tomatoes are a processed food made by drying fully ripe tomatoes to greatly reduce their moisture. As the water that makes up about 90% of a fresh tomato is removed, the umami becomes concentrated, making it an ingredient that adds deep richness and color to dishes in small amounts. In Italy they have long been used in pasta sauces and antipasti, and in Japan, farmers in regions such as Kyoto, Hokkaido and Okinawa have begun producing domestic dried tomatoes, drawing growing attention as a cooking ingredient. This article explains the basics of dried tomatoes for beginners, covering what types there are, how the flavor changes and how to use them for different purposes, and points you to dedicated articles for detailed usage, recipes, storage, choosing domestic products and sourcing for commercial use.

What are dried tomatoes? Characteristics and history
Dried tomatoes are called "Sun-Dried Tomato" in English and are a preserved food that has been made along the Italian and Mediterranean coasts for centuries. Alongside the traditional method of removing moisture by sun-drying, advances in processing such as low-temperature drying and freeze-drying now keep them in circulation worldwide year-round. Compared with fresh tomatoes, three characteristics stand out: the weight is concentrated to about 10–15%, umami components are concentrated, and they keep for a long time at room temperature.
| Comparison item | Fresh tomato | Dried tomato |
|---|---|---|
| Moisture | About 90% | About 10–15% |
| Umami | Contains glutamic acid but faint | Glutamic acid concentrated and rich |
| Storage period | About a week refrigerated | 6 months or more at room temperature |
| Flavor | Juicy and refreshing | Rich, with concentrated umami |
| How to use | Eating raw, salads | Stews, pasta, preserving in oil |
Types and processing styles of dried tomatoes
Dried tomatoes are divided into types along two axes: "variety" and "processing style." The differences by variety come from first-hand information gained at Agriture's production floor—practical, working-level knowledge not written in typical web articles.
Differences by variety
Having dried multiple varieties at Agriture, we've found that high-sugar cherry-tomato types (Aiko, Chika, etc.; Brix 7–10) bring sweetness to the fore and suit sweets and snacks, while tart large-fruit types (Momotaro, etc.; Brix 4–6) concentrate their umami and suit dashi and soup bases. The cooking-use San Marzano type has thick flesh and low moisture, making it ideal for authentic pasta sauces and pastes.
| Variety | Sugar content | Flavor after drying | Suitable use |
|---|---|---|---|
| Cherry-tomato type | Brix 7–10 | Strong sweetness | Snacks, nibbles, salads |
| Large-fruit type | Brix 4–6 | Balanced acidity and umami | Soup, dashi, simmered dishes |
| San Marzano type | Brix 4–5 | Meaty, concentrated umami | Pasta sauce, paste |
Characteristics by processing style
The three representative processing styles are "fully dried," "semi-dried," and "oil-packed." Fully dried keeps for 6 months or more at room temperature and is rehydrated before use in dishes. Semi-dried leaves some moisture for a juicy texture and requires refrigeration. Oil-packed is a ready-to-use type, suited to antipasti and bread toppings.
Flavor of dried tomatoes and where to use them
Because drying concentrates their umami, dried tomatoes add deep richness and color to dishes even in small amounts. Here is their character from four angles.
- Umami: Drying concentrates glutamate-based umami, so they can even stand in for dashi stock
- Glutamic acid: the same umami component as in kombu and cheese. The reason they work as a dashi or soup base
- Color: The color deepens with cooking, adding redness and gloss to dishes
- Texture: With the moisture gone, they become dense and release more flavor the more you chew
In yakuzen (Chinese medicinal cooking), fresh tomatoes are classified as having a cooling nature. Drying is said to make that nature somewhat milder, and they are used as an ingredient that is easy to include regardless of season.
