What does 100 g of freeze-dried lotus root put on your nutrition label?
About 22 g of dietary fibre and 2,550 mg of potassium per 100 g, with 0.5 g of fat and no added sugar. That is enough for “high fibre” and “high in potassium” in the EU and for “excellent source of fiber” on a 30 g US snack serving, from a one-line ingredient list that reads “lotus root”. The two numbers that need care are calories, which the US and the EU calculate differently, and sugars, which move with the root.
Freeze-dried lotus root is the peeled, sliced rhizome of Nelumbo nucifera, blanched and freeze-dried to 3–5% moisture and water activity below 0.30; it keeps the ivory colour and 7–9-hole wheel pattern of fresh lotus root, is crisp from the bag and rehydrates in hot water. Removing the water concentrates everything the fresh root carries about 4.6 times, which is why a modest vegetable becomes a strong fibre story once it is dried. This guide sets out the panel, the claims it carries in each market, and the lines your label artwork should take from a lot panel rather than from a table.
What is in 100 g, and in a 30 g serving?
The table gives typical values for 100% freeze-dried lotus root with nothing added, per 100 g and per 30 g, the US reference serving for chips and similar snacks. The EU column follows the EU declaration format.
| Nutrient | Per 100 g | Per 30 g serving | % DV per 30 g (US) | EU declaration per 100 g |
|---|---|---|---|---|
| Energy | 340–390 kcal (US basis) | 100–120 kcal | 1,360 kJ / 325 kcal | |
| Total fat | 0.5 g | 0.2 g | 0% | Fat 0.5 g |
| Saturated fat | 0.1 g | <0.1 g | 0% | of which saturates 0.1 g |
| Sodium | 185 mg | 55 mg | 2% | Salt 0.46 g |
| Potassium | 2,550 mg | 765 mg | 16% | 2,550 mg (128% NRV, declared with a claim) |
| Total carbohydrate | 79 g | 24 g | 9% | Carbohydrate 57 g |
| Dietary fibre | 22 g | 6.6 g | 24% | Fibre 22 g |
| Total sugars | 6–10 g (0 g added) | 2–3 g | of which sugars 6–10 g | |
| Protein | 12 g | 3.6 g | Protein 12 g |
Typical values calculated from reference dry-matter data for 100% freeze-dried lotus root; natural variation by season and root maturity applies. Lot nutrition panel available for label artwork.
Two lines change between the US and EU columns, and both catch label designers out. The EU declares carbohydrate without fibre, so 79 g of total carbohydrate on a US panel becomes 57 g on an EU panel. And the EU declares salt, not sodium: 185 mg of sodium is 0.46 g of salt. With no salt added at any step, every milligram of it is the root’s own.
The values are built from USDA FoodData Central data for raw lotus root, converted to a dry-matter basis at 4% moisture. That makes them reliable for formulation and for choosing claims. For the printed panel, use a lot panel from your own commercial lot, which FruitBuys arranges at an ISO/IEC 17025 accredited laboratory in the format your market needs.
Why is the sugar figure a range?
Because lotus root varies more in sugar than in anything else on the panel. The USDA sample of raw lotus root reports about 0.5 g of sugars per 100 g fresh weight. A 2024 study of six Asian lotus root cultivars (Dong et al., Foods, 13:2297) measured soluble sugars of 1.29–2.50% of fresh weight. Dried to 4% moisture, that spread becomes roughly 6–10 g per 100 g, all of it naturally occurring.
What moves it is the root itself: the cultivar and how mature the root is when it is lifted. For your label, that has one practical consequence. Sugars is the line most likely to differ between a reference table and your lot, so take it from the lot panel, and keep “no added sugar” as the front-of-pack message rather than a sugar number.
Why do US and EU calories differ for the same slice?
Because the two systems count fibre differently. In the EU, energy is calculated with fixed factors set in the labelling rules, and fibre counts at 2 kcal per gram, with carbohydrate declared without fibre. In the US, the label can be built on several accepted calculation methods, and depending on the method, more of the fibre is counted as carbohydrate at 4 kcal per gram.
Lotus root is 22% fibre, so the method matters more than it does for most foods: the same 100 g reads about 325 kcal on an EU panel and 340–390 kcal on a US panel. Neither figure is wrong. Use the EU figure on EU packs, the US figure on US packs, and do not copy a calorie line from one market’s artwork to the other’s.
Which claims can freeze-dried lotus root carry?
Fibre and potassium carry the front of the pack in both markets. The table checks each common claim against the plain, unseasoned root.
| Claim | EU (per 100 g) | US (per 30 g serving) | Use it? |
|---|---|---|---|
| High fibre / excellent source of fiber | ✔ 22 g, threshold 6 g | ✔ 24% DV, threshold 20% | Lead claim |
| High in potassium / good source of potassium | ✔ 128% NRV, threshold 30% | ✔ “Good source” at 16% DV; “high” needs 20% | Yes, with market wording |
| Low fat | ✔ 0.5 g, threshold 3 g | ✔ 0.2 g per serving | Yes |
| No added sugars | ✔ none added; add “contains naturally occurring sugars” | ✔ 0 g added sugars | Yes |
| Source of protein | ✔ about 15% of energy from protein, threshold 12% | Not used | EU only; confirm on the lot panel |
| Low sodium | ✘ 185 mg against 120 mg | Not recommended | Use “no added salt” instead |
| Sodium-free | ✘ | ✘ | No |
| Vitamin C | Not claimed | Not claimed | Only from a lot panel |
“No added salt” is the one sodium message that works in both markets and survives a retailer review, so it is the line FruitBuys recommends. Fresh lotus root is known for its vitamin C, but blanching and drying change it, and no reference table predicts what is left in a given lot. If vitamin C matters to your pack, it comes from a lot panel or not at all.
A seasoned or salt-blanched chip is a different panel. A light salt blanch lifts sodium to about 185–250 mg per 100 g, and a seasoning adds its own; recalculate the claims for that recipe before artwork is final.
Is freeze-dried lotus root low-carb or keto?
No, and it does not need to be. Per 100 g it carries 79 g of total carbohydrate and 22 g of fibre, so about 57 g of net carbohydrate; a 30 g serving carries about 17 g. That rules out a keto claim for a bag of plain lotus chips.
The story that works is fibre. If your product is a low-carb bowl or a keto-friendly mix, lotus root still has a place as an inclusion: 5 g of dice on top of a bowl adds about 3 g of net carbohydrate, and brings the wheel, the colour and a “with lotus root” line to the front of the pack. Dose it as a garnish, and build the carbohydrate story on the base.
What do the newer US label rules mean for a lotus root product?
They work in its favour. FDA’s updated definition of “healthy”, with a compliance date of February 25, 2028, ties the claim to food-group content plus limits on added sugars, sodium and saturated fat. A single-ingredient vegetable with no added sugar, 0.1 g of saturated fat and no added salt sits comfortably inside those limits; the figure to work out for your pack is the vegetable equivalent per serving.
FDA has also proposed a front-of-package nutrition box that rates saturated fat, sodium and added sugars as low, medium or high. The rule is still a proposal; as drafted, larger companies would have three years after a final rule to comply. On the figures above, a plain lotus root chip would read low on all three, which is a useful thing to know when you are choosing a hero ingredient for a range that will be on shelf for years.
Is lotus root good for you?
As food, it is a strong everyday vegetable. Fresh for fresh, raw lotus root carries roughly twice the fibre of raw potato per 100 g (about 4.9 g against 2 g in USDA data) and more potassium, with almost no fat. Freeze-drying keeps that profile and concentrates it into a crisp, shelf-stable piece with nothing added: no oil, no sugar, no salt.
For a pack, that translates into a short list of honest messages: one ingredient, high in fibre, a source of potassium, low in fat, no added sugar or salt. That is enough to sell on. Health claims beyond those nutrition facts are not supported by a nutrition table, so they stay off the pack. Lotus seeds are a different part of the plant with a different panel; their figures are in lotus seed nutrition facts.
Request a sample and a lot panel for your label
Order a sample in the format your product uses and ask for the nutrition panel on your commercial lot. The panel comes from an ISO/IEC 17025 accredited laboratory in the format your market requires, so your artwork, your claims and your lot line up before the first pouch is printed. Formats and private-label packing are covered in which freeze-dried lotus root format fits your line, how the freeze-dried slice compares with fried and frozen lotus root in dried vs freeze-dried vs frozen lotus root, and the full specification on the freeze-dried lotus root product page.
FAQ
How much fiber is in freeze-dried lotus root?
About 22 g per 100 g, or 6.6 g in a 30 g serving. That meets the EU “high fibre” level and 24% of the US Daily Value per serving.
How many calories are in 100 g of freeze-dried lotus root?
About 325 kcal (1,360 kJ) on an EU panel and 340–390 kcal on a US panel. The difference comes from how each system counts the energy in fibre.
How much sugar does freeze-dried lotus root contain?
6–10 g per 100 g, all naturally occurring, with 0 g added. The figure moves with cultivar and root maturity, so take it from the lot panel for your label.
Is lotus root keto-friendly?
Not as a snack on its own: about 57 g of net carbohydrate per 100 g. As a small inclusion, 5 g adds about 3 g of net carbohydrate.
Is dried lotus root high in sodium?
No. With no salt added it carries about 185 mg per 100 g, the root’s own sodium, or 0.46 g of salt on an EU panel. “No added salt” is the claim to use.
Does freeze-dried lotus root contain vitamin C?
Fresh lotus root does, but blanching and drying change it, so no figure is published. A lot panel can measure it if your pack needs it.
Is lotus root nutrition the same as lotus seed nutrition?
No. The root is high in fibre and low in fat; lotus seeds are a different part of the plant with more protein and a different panel.
