Plums are not a protein powerhouse — fresh raw plums provide only about 0.7 g of protein per 100 g — but for anyone tracking macronutrients, planning fruit-based meals, or building a plant-forward menu, those grams still matter. Dried plums (prunes) contain more per 100 g, at roughly 2.2 g, which is why comparing the same weight of fresh, canned, and dried forms is useful.
This plum protein per 100g calculator lets you select a plum product, adjust the protein-per-100g value to match a package label, and enter a serving size in grams. It instantly returns total protein, per-100g protein, and a serving-size breakdown you can copy into a food diary or macro spreadsheet.
Use it for meal prep, calorie tracking, or simply to understand how different plum products compare. The tool is designed for home cooks, nutrition students, dietitians, and fitness enthusiasts alike.

How the Protein Calculation Works
Every plum product has its own protein density. The calculator starts from the standard nutrition definition — grams of protein per 100 grams of edible fruit — and applies a simple proportional conversion:
For example, if a plum product label lists 1.4 g of protein in a 200 g serving, that translates to 0.7 g per 100 g. Enter 0.70 in the custom field to match exactly what is on your package. The tool also shows the per-100g value separately so you can compare plums with other fruit entries in your food diary, databases, or recipes that use per-100g formatting.
Reference Data: Plum Protein Values
| Plum product | Protein per 100 g |
|---|---|
| Fresh raw plums | 0.70 g |
| Canned plums, heavy syrup pack | 0.42 g |
| Canned plums, juice pack | 0.51 g |
| Dried plums (prunes), uncooked | 2.18 g |
| Prunes, stewed, no added sugar | 0.93 g |
These values are averages from USDA FoodData Central. Actual products vary, so treat them as informative benchmarks rather than lab-tested results for your specific batch.
Worked Examples
Fresh plum snack. You eat 150 g of raw plums. Using 0.70 g protein per 100 g: (0.70 ÷ 100) × 150 = 1.05 g protein.
Prunes on oatmeal. A 40 g serving of uncooked dried plums at 2.18 g per 100 g provides (2.18 ÷ 100) × 40 = 0.87 g protein.
Estimate from whole plums. One medium plum weighs about 66 g, so two plums are roughly 132 g. Raw plum protein for that portion is (0.70 ÷ 100) × 132 = 0.92 g. Use the plum-count estimate button in the calculator for quick real-life portions instead of weighing every piece.
Factors That Affect Accuracy
Plum protein varies by variety, ripeness, and growing conditions. Some cultivars are juicier, and more water per 100 g dilutes the protein percentage. Canning with syrup adds sugar and water, which lowers the protein per 100 g. Drying removes water, which concentrates protein along with calories. Even within the same bag, individual prunes differ slightly. If your goal is precise tracking, weigh the edible flesh and use the protein value printed on the package or a trusted nutrition database.
Frequently Asked Questions
- Why does my tracking app show 0.6 g instead of 0.7 g? Nutrition databases round and source data differently, and plum varieties can differ. The commonly cited USDA value is 0.7 g per 100 g. You can use the custom input to match your app.
- Can I use this calculator for plum jam, sauce, or baby food? Yes, if you know the protein per 100 g for that product. Added sugar lowers the relative protein percentage, so do not use the raw plum preset. Find the value on the label and enter it manually.
- Should I weigh plums with or without the pit? Weigh the edible flesh only. Plum pits account for a few grams and can make your serving size slightly wrong.
- Are prunes better for protein? Per 100 g they are higher because water is removed, but they are also higher in calories and natural sugars. For most diets, fresh plums and prunes both work as fruit servings; count protein and calories together.
- Can I calculate protein for a whole bowl of fruit salad? Yes. Weigh the plum portion separately, calculate its protein, then repeat for each fruit in the bowl. Per-100g calculators keep every ingredient comparable.
Where This Calculator Fits In Daily Nutrition
Fruit protein is easy to overlook in plant-forward and mixed diets. This tool is helpful for meal prep, macro-friendly snack planning, and checking whether a recipe with plums or prunes meets your daily protein goals. For another stone-fruit protein lookup, see the nectarine protein per 100g calculator. If you want a broader macro tool for complete meals, the protein-fat calculator is a practical companion.
Whether you are a dietitian writing a nutrition plan, an athlete tracking intake, or a home cook curious about fruit nutrition, per-100g values keep the comparison fair. Serving sizes change, but the nutrient density stays stable — and that is exactly what this calculator isolates.
