Nutmeg Whole, Powder, and Tea Cut: Bakery and Beverage Spec

Buyer’s snapshot

Myristica fragrans is the only tree that yields two separate spices: nutmeg, the hard seed kernel, and mace, the lacy crimson aril that wraps it. They share one ISO standard but carry different oil and flavour.
Volatile oil is the flavour a nutmeg buyer is paying for. Peer-reviewed analysis of trade samples against ISO 6577:2002 found volatile oil ranging from 4.6 to 12 ml/100g, averaging near 7.7 ml/100g in quality lots. Format decides how much of that oil survives to the point of use.
Whole (with or without shell), powder, and tea-bag cut are three specifications of the same kernel, not three products. Surface area is the single axis that trades aroma retention against extraction speed and dust.
Silk Foods Ceylon (SFC) supplies whole nutmeg, nutmeg powder, nutmeg tea cut, and mace from a Matale facility under BRCGS and FSSC 22000 V6, with saturated-steam microbial treatment and a 50 kg first-order MOQ per format.
For bakery and beverage formulators choosing a nutmeg format, this post is the spec. For buyers who only need “nutmeg, cheapest landed,” it will read as over-engineered.

Most buyers order “nutmeg” and let the supplier pick the cut. That is where the aroma quietly leaks away before the spice ever reaches a batter or a brew. A whole seed, a fine powder, and a tea-bag cut are the same Myristica fragrans, but they hold volatile oil, brew, dust, and store differently enough that the wrong format costs a formulator either flavour or yield. ISO 6577:2002 fixes the species and the cleanliness floor. The format decides almost everything after that. This piece is for the bakery, beverage, and tea buyers who want the cut written on the spec sheet, not left to the packer. It sits alongside the broader B2B sourcing guide to Ceylon spices, and the format discipline mirrors the one set out for Ceylon cloves and dried ginger.

The three nutmeg formats, and the one decision behind them

Nutmeg ships in three trade formats: whole seed (with shell or without shell), ground powder, and tea-bag cut. They differ on one axis, which is surface area. More cutting means faster aroma release and faster aroma loss. Whole holds the most volatile oil and the longest shelf life; powder releases fastest and oxidises soonest. Tea cut sits in between, sized to brew clean in a bag.

Whole nutmeg is the dried seed kernel itself, an oval ovoid stone roughly 2 to 3 cm long with a grooved surface. With-shell nutmeg keeps the brittle outer testa on for the longest protection in transit; without-shell (the shelled kernel) is ready to grind. The buyer grates or mills it at the point of use, which is why whole is the format extractors and grind-in-house brands prefer. Powder is milled nutmeg, specified by mesh, and it disperses instantly into a dough, a custard base, or a spice premix. Tea-bag cut is a small irregular granule, coarse enough to drop the fines that cloud a cup, fine enough to give up its oil fast in hot water. Each format answers one question: how fast does the buyer want the nutmeg to release its oil, and how long does it need to sit on a shelf first.

What is the difference between nutmeg and mace?

Nutmeg and mace come from the same fruit of Myristica fragrans, but they are two distinct spices. Nutmeg is the hard inner seed kernel; mace is the lacy crimson-to-amber aril that wraps the seed, peeled off and dried separately. Both fall under ISO 6577:2002, the trade specification for nutmeg (whole or broken) and mace (whole or in pieces). Mace runs a more delicate, slightly more bitter and aromatic profile, and it commands a higher price per kilo because there is far less of it per fruit.

For a formulator, the practical split is this. Nutmeg powder is the workhorse for baked goods, custards, sauces, and spiced beverages. Mace is the finer note, used where a cleaner, brighter aroma and a paler colour matter, in light-coloured sauces, premium bakery, and some beverage and savoury blends. Sri Lanka is a recognised origin for both, serving roughly 5% of global nutmeg demand and around 7% of global mace demand (Sri Lanka Export Development Board, Ceylon Nutmeg and Mace, 2024). A buyer sourcing one can usually source the other from the same lot of fruit, under the same certification stack, which is part of why single-origin Ceylon supply simplifies a multi-SKU spice programme.

Matching the nutmeg format to the end product

For bakery, powder wins on dispersion. For tea and ready-to-drink beverages, tea-bag cut wins on brew clarity and clean extraction. For extractors, spice millers, and brands that grind to order, whole seed wins on oil retention and shelf life. The table below maps each format to its application and its main trade-off.

Format	Typical form	Best-fit applications	Main trade-off
Whole, with shell	Intact seed, outer testa on	Long storage, extractors, brands grinding in-house, retail whole-spice packs	Longest shelf life and highest oil retention, but the buyer must shell and grind it
Whole, without shell	Shelled kernel, ready to grind	Spice millers, in-house grinding, grater-pack retail	High oil retention with less prep, but shorter protection than with-shell
Powder (ground)	Milled, specify mesh (e.g. 30 to 60 mesh)	Bakery, custards, sauces, spice and beverage premixes, capsule fill	Fastest dispersion, but the fastest volatile-oil loss and the most dust
Tea-bag cut	Small granule, roughly 1 to 3 mm	Functional and spiced tea bags, RTD infusions, mulled and chai blends	Fast clean extraction with low fines, but less shelf-stable than whole

Buyers running this table usually split into two camps: spice and beverage brands specifying bulk nutmeg against their own blend or co-packer, and brands that want a finished pack under their own label. Silk Route Ventures (SRV) supplies both, and the format spec is identical whether the order is a bulk raw-material purchase or a private-label retail SKU. The same one-axis discipline, surface area traded against retention, runs across the spice rack, from cardamom grade tiers to black pepper origin selection.

What does volatile oil content tell a nutmeg buyer?

Volatile oil is the steam-distillable aromatic fraction, and it is the flavour the buyer is paying for. Peer-reviewed analysis of nutmeg trade samples assessed against ISO 6577:2002 found volatile oil ranging from 4.6 to 12 ml/100g, averaging close to 7.7 ml/100g in the quality lots (Food Control, distinguishing quality from low-grade nutmeg, 2019). The same study used analytical fingerprinting because nutmeg is one of the more adulterated spices in trade, often cut with spent, low-oil material. A volatile-oil figure on the COA is the buyer’s first defence.

Two compounds inside that oil matter to a formulator. The aroma is carried by terpenes that make up roughly 90% of the oil. The signature warm note, and the toxicology, sit with myristicin, which runs about 5 to 12% of nutmeg oil. Myristicin is why nutmeg works at a pinch and turns unpleasant in quantity, so beverage formulators dose to flavour, not to extract. The US FDA lists nutmeg oil as generally recognised as safe for use as a flavouring at the low levels customary in food (US FDA, 21 CFR 182.20). For a beverage or tea brand, the takeaway is simple: specify the volatile-oil floor for flavour strength, and keep the use level in the flavouring range rather than the functional-dose range.

Specifying nutmeg on an RFQ

A defensible nutmeg RFQ names six things: the botanical species, the volatile-oil floor, the moisture and ash ceilings, the format with its cut size or mesh, the microbial-reduction method, and the pesticide and ethylene-oxide position for the destination market. Leaving any of these to the packer is how a buyer ends up with a low-oil lot or a border rejection.

Name the species so the lot is not Papua-type material sold as true nutmeg. Put the volatile-oil number on the COA rather than accepting a generic “aromatic” descriptor, because the oil is the flavour being purchased, and because low-oil adulteration is a documented problem in this spice. State the moisture ceiling and the ash ceiling, since ISO 6577:2002 references a 3.0% total-ash maximum and high ash is a sand-and-grit signal. State the format and its mesh or cut size. Then settle the microbial method, which carries more weight than buyers expect: ethylene oxide is a non-approved substance in the EU, held to a 0.1 mg/kg sum limit, and ground spices draw extra border testing for exactly this residue. Saturated-steam treatment sidesteps the ethylene-oxide question entirely. Finish with a heavy-metals panel and a pesticide screen aligned to the destination, and a COA on every batch.

In Q1 2026, the SRV procurement desk saw the same correction twice in a month. Each was a US beverage brand that had ordered “nutmeg powder” for a chai and mulled-cider line, then found the aroma fading inside the warehousing window and the fines bridging in the sachet filler. The fix was not a better powder. It was the right format, a tea-bag cut for the brewed line and whole seed milled closer to use for the premix. That lesson costs nothing if it is on the spec sheet before the first order, and a re-blend if it is not.

Buyer’s checklist: specifying a nutmeg format

Botanical species (Myristica fragrans) confirmed in writing, Papua-type excluded
Format named: whole with shell, whole without shell, powder, or tea-bag cut
Cut size in mm for tea cut, or mesh for powder
Volatile-oil floor on the COA (specify the ml/100g minimum for the grade)
Moisture ceiling and total-ash ceiling (ISO 6577:2002 references 3.0% ash maximum)
Microbial-reduction method stated (steam preferred over ethylene oxide)
Pesticide and ethylene-oxide panel aligned to the destination market
Sample dispatched against the spec before any PO

Where does Ceylon nutmeg fit for a sourcing buyer?

Sri Lanka is a quality-niche nutmeg origin rather than a volume giant. Nutmeg is grown mainly in the Matale, Kandy, and Kegalle districts across roughly 2,788 hectares, with about 80% of the planting in the Kandy district on small and mid-scale holdings, and the crop carries the Ceylon Nutmeg geographical indication (Sri Lanka Export Development Board, 2024). The country serves around 5% of global nutmeg demand and 7% of global mace demand. On the buyer side, demand is steady: the global nutmeg market sat somewhere between USD 1.4 and 2.7 billion in 2024 to 2025, depending on which research firm’s methodology you accept, growing at roughly 5% a year (Mordor Intelligence and SkyQuest, 2025). For a sourcing buyer, the draw of a Ceylon origin is a single source that supplies nutmeg in every format, plus mace, under one certification stack.

Silk Route Ventures supplies bulk nutmeg and mace, and Silk Foods Ceylon mills and cuts nutmeg to format at the Matale facility, roughly 1 km from Nalanda Gedige in the geographic centre of Sri Lanka. Whole, powder, and tea-bag cut come off the same spice and herb line at 100 to 200 kg per hour, under BRCGS and FSSC 22000 V6, with saturated-steam microbial reduction that keeps ethylene oxide out of the EU residue conversation. First-order MOQ is 50 kg per format. Buyers new to the origin can run the facility through a standard Sri Lankan supplier evaluation checklist before the first PO. Samples ship by international courier in 3 to 5 business days; production lead time is 2 to 3 weeks from PO to dispatch, with sea freight at 4 to 5 weeks to the US and 3 to 4 weeks to the EU and Australia. Where a buyer simply wants the lowest landed price with no format discipline, a high-volume lot from Indonesia or Grenada is the more honest answer. SRV’s case is format precision plus certification, not the cheapest shelf price.

FAQ

Is mace the same as nutmeg?

No. Both come from the fruit of Myristica fragrans, but nutmeg is the hard inner seed kernel and mace is the lacy crimson aril that wraps the seed, dried separately. Mace is more delicate and aromatic, paler in use, and costs more per kilo because there is far less of it per fruit. Both fall under ISO 6577:2002.

What nutmeg format is best for beverages and tea?

Tea-bag cut is best for brewed beverages and tea bags: a small granule, roughly 1 to 3 mm, that extracts fast and clean with low fines, so it does not cloud the cup or bridge in sachet-filling machines. For premixes and RTD bases, powder disperses faster but loses aroma sooner, so order it closer to production.

How much myristicin is in nutmeg, and is it safe in beverages?

Myristicin runs about 5 to 12% of nutmeg’s volatile oil. At culinary and flavouring levels it is safe; the US FDA lists nutmeg oil as generally recognised as safe for flavouring use (21 CFR 182.20). The discipline for beverage formulators is to dose nutmeg to flavour, not to a functional extract level, and to specify the volatile-oil floor for consistent strength.

What volatile-oil content should I specify for bulk nutmeg?

Quality nutmeg carries volatile oil in the 4.6 to 12 ml/100g range, averaging near 7.7 ml/100g in good lots assessed against ISO 6577:2002. Tea and bakery buyers often specify a floor of 6.5 ml/100g and above. Ask for the volatile-oil figure on every batch COA, since low-oil adulteration is a documented issue in the nutmeg trade.

Does Silk Route Ventures supply private-label or bulk nutmeg with BRCGS and FSSC?

Yes. Silk Foods Ceylon mills and cuts nutmeg to whole, powder, or tea-bag cut, and supplies mace, at its Matale facility under BRCGS and FSSC 22000 V6, with saturated-steam microbial treatment and a 50 kg first-order MOQ per format.
