Raw jamun fruit (Syzygium cumini) has about 15–16 g carbohydrates per 100 g; serving size and preparation change the carb count.
Jamun, also called java plum or black plum, is a juicy, deep-purple stone fruit with a pleasantly tart finish. If you’re counting carbs for everyday eating or for recipe planning, the headline is simple: most fresh jamun is water and natural sugars, with a modest fiber lift. Below you’ll find the exact carbohydrate ranges by weight and common portions, plus how juicing, cooking, or turning jamun into jam shifts the numbers.
Carbohydrates In Jamun Fruit — By Serving And Prep
Fresh jamun carries roughly 15–16 g carbohydrates per 100 g, with small swings in different datasets. To make that easier to use in a kitchen or market setting, here’s a quick table of typical portions and how the carbohydrates change with preparation.
Table #1: Broad, in-depth; within first 30%
| Serving / Form | Carbohydrates (g) | Notes |
|---|---|---|
| 100 g raw fruit | ~15.5 | Baseline reference for fresh jamun pulp with skin. |
| 1 cup raw (≈135 g) | ~21 | Volume varies with fruit size and seed ratio. |
| 3 fruits small (≈25 g total) | ~3.9 | Handy snack estimate when weighing isn’t practical. |
| Unsweetened juice (100 ml) | ~10–12 | Juicing removes fiber; carbs concentrate slightly. |
| Homemade jam (1 tbsp, sweetened) | ~12–14 | Added sugar drives carbs; check your recipe ratio. |
| Chutney (1 tbsp, with sugar) | ~7–10 | Depends on sugar and fruit share in the pan. |
| Dried seed powder (1 tsp) | ~1–2 | Used in traditional recipes; not the same as pulp. |
What Counts As “Carbs” In Jamun
In fresh jamun, most carbohydrates come from natural sugars (glucose and fructose) with a small fiber portion. Lab references list ~0.6–0.9 g fiber per 100 g, which is modest. The rest of the carb figure is sugar plus small non-sugar components measured by difference. When you press jamun into juice, fiber drops and sugars concentrate, so carbs per cup usually climb.
How Variety, Ripeness, And Water Content Shift The Numbers
Jamun varies by cultivar and rainfall. Ripe, sweeter lots carry a little more sugar and slightly fewer grams of fiber per 100 g because water share and sugar share change as the fruit ripens. White or pale varieties can taste milder but follow similar carbohydrate ranges. If you’re tracking precisely, weighing your actual portion beats counting pieces.
Carbohydrates In Jamun Fruit For Common Goals
Everyday Eating
If you eyeball portions, use these safe working figures: a small handful (6–8 fruits, ~50–70 g without big seeds) lands near 8–11 g carbs. A generous bowl serving can double that. Fresh fruit brings tart flavor with less carbohydrate hit than many tropical fruits.
Cooking And Preserving
Cooking jamun into jams, syrups, or chutneys changes the math fast. Most spoonable recipes add sugar gram-for-gram or close to it, so a tablespoon can carry well over 10 g carbs. Thick syrup or cordial concentrates even more; measure by finished weight or check your nutrition calculator if you bottle batches.
Juice And Smoothies
Unsweetened jamun juice keeps the fruit’s sugars but strips the pulp fiber. If you’re blending, include whole pulp where possible to hold a little fiber and dilute with water or lower-sugar fruits to keep total carbs steady.
Ingredient Labels, Market Buys, And Home Weighing
Packaged jamun drinks or candies can show wide swings. Scan the label for “added sugars” and serving size. For fresh fruit from street vendors or markets, weigh once at home to learn your bowl and spoon weights—then it’s easy to repeat accurate servings without a scale.
Carbs In Jamun Vs Other Fruits (Per 100 g)
Here’s a simple comparison to keep expectations straight. Values reflect typical database entries for raw fruit.
Table #2: After 60% of the article
| Fruit (Raw, 100 g) | Carbohydrates (g) | Notes |
|---|---|---|
| Jamun (java plum) | ~15–16 | Tart, astringent skin; modest fiber. |
| Apple | ~13–14 | Similar range; fiber higher with peel. |
| Orange | ~11–12 | Lower carb; water-rich segments. |
| Banana | ~22–23 | Starch shifts to sugars as it ripens. |
| Mango | ~15 | Close to jamun when measured by weight. |
| Grapes | ~17 | Higher sugars per bite. |
| Guava | ~14 | Often higher fiber than jamun. |
How To Estimate Carbs In Your Own Jamun Bowl
Quick Weigh Method
- Weigh your empty bowl once and note the weight.
- Add jamun, weigh again, and subtract the bowl weight.
- Multiply grams by 0.155 for a solid estimate of total carbs.
Example: 140 g fresh jamun × 0.155 ≈ 21.7 g carbohydrates.
No-Scale Method
- Small snack (5–6 fruits): ~6–8 g carbs.
- Heaped cup: ~21 g carbs.
- Juice glass (200 ml, unsweetened): ~20–24 g carbs.
Nutrient Sources And Why Numbers Differ
Different laboratories and tables report slightly different values because fruit changes with soil, weather, and maturity. Two high-quality references widely used by dietitians are the Indian Food Composition Tables and the USDA-derived datasets often republished in tools and summaries. A peer-reviewed overview hosted on NIH PubMed Central also summarizes composition across studies. When precision matters—for clinical logging or product labeling—anchor to one dataset and keep it consistent across recipes.
Practical Ways To Keep Carbs In Check With Jamun
Portion Smart
Pick a portion target before you start snacking. A small bowl delivers the tart flavor without a big carbohydrate load. Chilled fruit tightens texture and makes smaller servings more satisfying.
Balance In Recipes
In smoothies, pair jamun with cucumber, spinach, or unsweetened yogurt to spread the carbs across more volume. In chutneys, use less sugar and more vinegar, ginger, and whole spices for brightness without extra grams.
Use The Seed And Skin Wisely
The seed and the astringent skin show up in research and traditional preparations. They aren’t a carb bargain by themselves but can add color and body. If you add seed powder to recipes, count it modestly and focus your carb math on the pulp and sugar you actually eat.
Frequently Mixed-Up Terms
Jamun, Java Plum, Black Plum
All three labels point to Syzygium cumini. Regional stores may switch names on signboards, but the carbohydrate reference values remain similar across sources when measured by weight.
Jam Vs Chutney Vs Syrup
Jam and syrup usually add a lot of sugar, so tablespoons can rival a full snack’s carbs. A savory chutney can run lower if you rely on spices and acid for flavor and keep added sugar lean.
Bottom Line On Carbohydrates In Jamun Fruit
Fresh jamun sits in a moderate carbohydrate band—about 15–16 g per 100 g—with taste and ripeness nudging it up or down. Portion size and added sugar are the two levers that move your total more than anything else. Use the quick math above, favor fresh fruit over sugary preserves, and you’ll know exactly what’s in your bowl.
