Introduction to Plum Concentrate
Plum concentrate is a powerful ingredient made by cooking down plum juice to remove most of its water content, resulting in a thick, potent syrup. This process intensifies the fruit's natural sweetness, tartness, and vibrant color, making it a valuable addition to both commercial food production and home cooking. While regular plum concentrate is made from fresh plums, some types, like Ume plum extract, are specifically made from certain plum varieties and prized for unique flavor profiles. The resulting concentrate is a convenient, shelf-stable product that can be rehydrated or used directly to impart a deep, fruity essence.
Culinary Uses: Enhancing Flavor and Texture
Plum concentrate's versatility in the kitchen is one of its biggest assets. It can be a simple one-to-one substitute for pomegranate molasses, a flavor booster, or a natural sweetener in various dishes.
Sauces and Marinades
- Marinades: In meat and poultry marinades, plum concentrate adds a tangy sweetness that tenderizes and imparts a beautiful color. Korean plum extract (Maesil) is particularly popular for this purpose, as it is known to soften meat and eliminate gamey odors.
- Barbecue and Braising Sauces: Its complex flavor can deepen and round out the acidity in tomato-based sauces or complement the richness of braising liquids. Some recipes use it to create a healthier, no-added-sugar BBQ sauce.
- Asian Cuisine: In Southeast Asian sauces like sambal or satay, it provides a balanced sweet and sour base. It can be used in teriyaki-style sauces to add a fruity twist.
Baking and Desserts
- Natural Sweetener: Plum concentrate can replace refined sugar in recipes, especially for fruit fillings, glazes, and frostings. Its natural sweetness and fiber content can also help retain moisture in baked goods.
- Moisture and Color: In cakes, muffins, and quick breads, adding a small amount of concentrate can subtly enhance caramelization and maintain moisture. It can also add a rich, natural color to fillings or confectionery.
- Jams and Jellies: It is a key ingredient in fruit snacks, jams, and jellies, offering a cost-effective and flavorful way to produce consistent, high-quality products.
Beverages and Cocktails
- Reconstituted Juice: For manufacturers, the concentrate is a cost-effective way to produce plum juice. For home use, you can mix it with water to create a simple, refreshing beverage.
- Smoothies and Wellness Drinks: Plum concentrate adds a burst of fruit flavor and nutrients to smoothies and other functional beverages. Korean plum tea (Maesil Cha) is a popular preparation, made by simply diluting the extract with water.
- Cocktails and Mocktails: Bartenders can use plum concentrate to add a unique, fruity element to cocktails and non-alcoholic drinks.
Health and Nutritional Applications
Beyond its culinary uses, plum concentrate offers several health-related benefits, often found in nutritional supplements and wellness products.
Digestive Health
- Laxative Effect: While prunes are more famously known for their laxative properties due to high sorbitol content, fresh plum concentrate also contains compounds that aid digestion. It can help regulate bowel movements and improve overall gut health.
- Antioxidant Source: Plums are rich in antioxidants, including polyphenols and vitamin C. These compounds help neutralize free radicals, reduce oxidative stress, and support the immune system.
Other Health Benefits
- Alkalizing Properties: Ume plum extract, in particular, is considered an alkaline food in Japan, helping to balance the body's pH levels.
- Liver Support: Some studies suggest that the picric acid in Ume plum products can aid liver function.
- Blood Circulation: The compound mumefural found in ume extract is believed to improve blood flow.
Industrial Applications: Food Manufacturing
For food and beverage manufacturers, plum concentrate is a workhorse ingredient used for several functional purposes.
As a Browning Agent
- Fresh plum concentrate can assist with browning in baked goods, giving them a more appealing, caramelized look without the need for artificial coloring.
For Moisture Binding
- In meat and bakery applications, plum concentrate can bind moisture, helping products stay fresh and juicy for longer. This is especially useful in gluten-free products, which can sometimes be dry.
As a Natural Preservative
- Certain plum concentrates can help suppress lipid oxidation, which causes rancidity in whole-grain baked goods, extending their shelf life.
Plum Concentrate vs. Prune Concentrate
While both come from the same fruit, their uses and properties differ slightly due to the manufacturing process. Prune concentrate is made from dried plums, while plum concentrate uses fresh fruit.
| Feature | Plum Concentrate (Fresh) | Prune Concentrate (Dried) |
|---|---|---|
| Starting Fruit | Fresh plums | Dried plums (prunes) |
| Flavor Profile | Often described as tart cherry-like or intensely sweet depending on the plum variety. | Rich, earthy, and deep, with a robust sweetness. |
| Laxative Effect | Mild effect due to sugar alcohols like sorbitol and phenolic compounds. | Stronger effect due to higher sorbitol concentration from the drying process. |
| Nutritional Content | High in vitamin C and plant antioxidants. | Higher in fiber, magnesium, B vitamins, and potassium. |
| Best for | Enhancing fresh fruit flavor, adding vibrant color, and light sweetness. | Deepening flavor, acting as a natural humectant in baked goods, and digestive support. |

How to Make a Simple Plum Concentrate at Home
If you're inspired to create your own plum concentrate, here is a basic recipe:
- Ingredients: 2.2 lbs green or ripe plums, 2.2 lbs white rock sugar, shochu (or vodka) for sterilization.
- Preparation: Thoroughly wash and dry plums, removing stems. Sterilize a large glass jar by washing it, rinsing with boiling water, and wiping with shochu.
- Layering: Alternate layers of plums and rock sugar in the jar, making sure the final layer of sugar completely covers the plums.
- Fermentation: Seal the jar and store it in a cool, dark place. Gently tilt or shake the jar twice daily to coat the plums with syrup and prevent mold. This process can take several weeks until the plums are shriveled and the sugar is dissolved.
- Finishing: Once the syrup is ready, strain out the plums. For a shelf-stable concentrate, you can gently simmer the liquid for 15 minutes to reduce foam, then transfer to sterilized jars and seal for storage.
Conclusion
The uses of plum concentrate span far beyond a simple juice additive. Its intense flavor and nutritional profile make it a valuable tool in culinary arts, from perfecting sauces and marinades to enriching baked goods and beverages. On the health front, it offers digestive support and a potent dose of antioxidants, while in manufacturing, it serves as a natural coloring, flavoring, and moisture-retaining agent. By understanding the specific type of concentrate—whether from fresh plums, prunes, or a variety like Ume—one can better harness its unique properties. Ultimately, this concentrated fruit offers a flavorful and functional solution for a wide range of applications.
How to make plum concentrate - A delicious condiment from Japanese plum (Ume) extract
For a specific type of concentrate, known as Ume plum extract (or bainiku ekisu), the process involves a more intense reduction. One kilo of fresh Ume plums can be reduced to just 20 grams of a thick, dark paste. This highly potent concentrate is often used in smaller quantities for medicinal purposes or to add a powerful flavor to dishes.
What is the difference between plum juice and plum concentrate?
The primary difference lies in the water content. Plum concentrate has had most of its water evaporated, making it a smaller, more potent product that is easier and more cost-effective to transport. Plum juice, by contrast, is the single-strength juice, which is simply pressed from the fruit. Manufacturers often reconstitute concentrate by adding water back in to make juice.
How can I use plum concentrate as a substitute for pomegranate molasses?
Because of its similar tangy-sweet flavor profile and viscous texture, plum concentrate is an excellent one-to-one substitute for pomegranate molasses in recipes for marinades, salad dressings, and sauces. The slight difference in fruit flavor can add an interesting new dimension to your dish.
Can plum concentrate be used for weight loss?
While not a magic bullet, both plums and prunes are low in kilojoules and can be part of a weight management plan. Prunes have higher fiber and sorbitol content, which can aid in promoting satiety and regulating digestion. Using plum concentrate as a natural sweetener in place of refined sugar can help reduce calorie intake.
What is plum concentrate used for?
Plum concentrate is used in a wide variety of food applications, including sauces, marinades, beverages (juices, teas, cocktails), baked goods (cakes, muffins), and desserts (jams, jellies). It is also used in the health industry in supplements and wellness drinks and in food manufacturing as a natural flavor, color, and moisture-retaining agent.
Why is plum concentrate used in the tobacco industry?
Some tobacco manufacturers have reportedly used prune juice concentrate to add flavor to tobacco. While prune juice concentrate is safe for food products, its use in tobacco does not imply safety when inhaled. Research has not yet identified all the compounds produced when burning these additives.
Is there a difference between regular plum concentrate and Ume plum concentrate?
Yes, regular plum concentrate is typically made from a variety of fresh plums, while Ume plum concentrate is specifically made from the Ume plum (Prunus mume). Ume plum concentrate, known as bainiku ekisu, is a highly potent, traditional Japanese product that offers unique health benefits like improved blood flow and fatigue recovery, but lacks the high salt content of its pickled counterpart, umeboshi.
