What microbiological standards apply to dried Nettle leaf supplied for food production in the EU?

Dried Nettle leaf for food use must meet the process hygiene and food safety criteria set out in EU Reg. 2073/2005. At minimum, the batch CoA should report Total Aerobic Count, Enterobacteriaceae, *Salmonella* spp. (absent per analytical unit), *E. coli*, and *Listeria monocytogenes* (absent where relevant to the finished product). Additional targets such as *Bacillus cereus* may be required depending on your end application and customer codes of practice.

What Brix level should I specify for Nettle juice concentrate used in functional beverages?

For most functional beverage applications, Nettle juice concentrate at ≥ 40 °Brix (measured by refractometer at 20 °C) is the standard commercial starting point. Higher-Brix fractions up to approximately 60–65 °Brix are available for applications where water addition is tightly controlled. Always request pH, colour stability data, and the heat-treatment parameters applied during concentration, as these affect both shelf life and reformulation flexibility.

Does EU-Organic certification under Reg. 2018/848 require a transaction certificate for every Nettle shipment?

Yes. Under EU-Organic Reg. 2018/848, organic goods must be accompanied by a transaction certificate (TC) issued by the control body each time a certified product changes hands in the supply chain. As the food business operator making organic label claims, you need the TC at the time of purchase to maintain the integrity of your own organic certification audit trail. TANDOR provides TCs as part of the standard documentation package for organic Nettle lots.

What is the realistic minimum order quantity for a first trial of organic dried Nettle C&S from TANDOR?

Trial orders for dried Cut-and-Sifted Nettle typically start from 100 kg, which is sufficient to conduct intake testing, line trials, and a sensory evaluation before committing to a full campaign volume. Organic lots may carry a higher practical minimum depending on the certified batch size available from origin at the time of enquiry. Contact TANDOR with your specification and required delivery window to confirm availability and exact MOQ for your trial.

Organic Nettle Sourcing for Food & Beverage

Which Nettle Form Is Right for Your Application?

The correct physical form of Nettle determines your shelf life, blending behaviour, and regulatory paperwork before you write a single purchase order.

IQF (Individually Quick-Frozen) Nettle Leaf

IQF is the preferred form for ready-meal manufacturers, soup producers, and savory-filling lines that need intact leaf structure and minimal colour loss. Blanching prior to freezing inactivates stinging trichomes, making the material safe to handle on the line. Key specifications to verify on the Certificate of Analysis (CoA):

Moisture retained post-thaw: typically ≤ 92 % (product-specific; confirm with your formulation team)
Colour: vivid green — ASTA colour measurement or visual grading to agreed reference
Extraneous matter: ≤ 0.5 % by weight, per agreed food-grade specification
Microbiological limits: Total aerobic count, Enterobacteriaceae, *Salmonella* spp., *Listeria monocytogenes*, and *E. coli* tested per EU Reg. 2073/2005 food safety criteria; *Listeria* and *Salmonella* must be absent in the stated analytical unit

IQF Nettle is packed in polylined cartons (typically 10 kg) and requires cold-chain logistics throughout — factor this into your landed-cost calculation.

Dried Cut-and-Sifted (C&S) Nettle Leaf

Dried C&S is the workhorse format for herbal tea blenders, dry soup-mix producers, and functional food manufacturers. Critical specs:

Moisture content: ≤ 10 % (common food-grade benchmark; stricter limits available on request)
Particle size: 2–5 mm sieve fraction standard; finer mesh cuts available for encapsulation or seasoning blends
Ash content and acid-insoluble ash: indicators of soil contamination and processing hygiene — request these figures on every CoA
Foreign matter and stem content: define your tolerance in the purchase specification before order confirmation
Microbiological panel per EU Reg. 2073/2005 plus *Bacillus cereus* where relevant to your end application

Dried C&S ships ambient at significantly lower freight cost than IQF, with a typical shelf life of 24 months under correct storage (cool, dry, dark, sealed).

Nettle Juice Concentrate

Concentrate suits functional beverage producers, nutraceutical drink manufacturers, and clean-label shot brands. Brix is the defining commercial parameter:

Standard commercial concentrates run at ≥ 40 °Brix (refractometer, 20 °C); higher-Brix fractions (60–65 °Brix) are available but require careful viscosity management on your filling line
pH typically 4.5–5.5 (native); ensure compatibility with your target beverage matrix before committing to volume
Colour stability: chlorophyll degradation accelerates above 70 °C — specify heat-treatment parameters and storage temperature in your technical agreement
Microbiological standard: yeast & mould counts are the primary concern in high-Brix concentrates; confirm limits aligned with EU Reg. 2073/2005 process hygiene criteria
Heavy metal and pesticide residue screens are mandatory; results should appear on every batch CoA

Food-Grade Compliance: What Your CoA Must Cover

For any Nettle form entering a food or beverage supply chain, a batch-specific Certificate of Analysis should document:

Botanical identity confirmation (macroscopic/microscopic or HPTLC)
Pesticide residue screen against EU MRL limits set under Reg. (EC) 396/2005
Heavy metals: Lead, Cadmium, Arsenic, Mercury — against limits in Reg. (EC) 1881/2006 and its amendments
Mycotoxins: Aflatoxins (B1, B2, G1, G2) and Ochratoxin A, per Reg. 1881/2006
Microbiological criteria per EU Reg. 2073/2005
Allergen declaration: Nettle itself is not a listed EU allergen under Reg. (EU) 1169/2011, but cross-contamination panels (gluten, nuts, soy) matter if the processing facility handles multiple botanicals — request the site's allergen management policy
PAH and solvent residues where concentrate or extract forms are supplied

Organic Certification: What EU-Organic Actually Means for Buyers

Nettle certified under EU-Organic Reg. 2018/848 (which replaced Reg. 834/2007 from January 2022) carries an EU organic logo and a traceable certification body code on pack. For food producers making organic label claims, this is non-negotiable.

Practical implications for procurement:

The supplying farm or wildcraft operation must hold a valid certificate from an accredited control body (e.g. ECOCERT, Soil Association, LACON, or Romanian equivalents recognised under Reg. 2018/848)
Segregation and documentation of organic material throughout the processing chain must be verifiable — ask for the transaction certificates (TCs) at time of order, not at delivery
Annual re-certification means you should check certificate validity dates before each campaign, especially for seasonal crops

---

Origin, MOQ, and Processing Realities

Nettle for food use is commercially cultivated and wildcrafted across Romania, Poland, North Macedonia, Albania, and Bulgaria — all common EU or EU-adjacent supply origins. Origin matters because soil conditions, harvest season (spring leaf vs. mature summer), and post-harvest drying method (shade-dried vs. tunnel-dried) directly affect colour, chlorophyll content, and microbial load.

Typical MOQ guidance:

Dried C&S: from 100 kg per lot for trial orders; commercial campaigns commonly from 500 kg
IQF: pallet quantities (typically 300–500 kg minimum) due to cold-chain handling constraints
Concentrate: from 50 kg (drum) for trials; full campaigns typically from 200 kg

MOQs vary by origin, season, and whether organic or conventional material is required — confirm with TANDOR at enquiry stage.

Why Source Nettle Through TANDOR?

TANDOR is a Romania-based sourcing intermediary with direct relationships across multiple Nettle-producing origins in southeastern and central Europe. For food and beverage buyers, the practical advantages are:

Multi-origin access: if one origin fails a pesticide screen or has a short harvest, alternative supply can be activated without retendering
Batch-specific CoA supplied as standard: you receive analytical data before goods are released, not after they arrive at your goods-in dock
EU-Organic certified lines available: with transaction certificate support for your own organic certification audits
Specification alignment before order: TANDOR works from your finished-product spec backward to define the raw-material requirements — reducing rejection risk at intake
EU regulatory familiarity: supply documentation is structured for EU food business operators, covering traceability requirements under Reg. (EC) 178/2002
