Spice Production Process: Bulk Spice to Labeled Jar

The spice blend production process: receiving bulk spices, weighing the blend, mixing, sifting, filling by weight, sealing and coding, and a run sheet.

A small spice blend business runs in eight steps: receive and check the bulk spices, store them dry and sealed, weigh the blend by the recipe, mix it evenly, sift out lumps and foreign matter, fill each jar by weight, seal and label, and code each jar with a lot. Two steps make or break a blend. Receiving is where quality starts: each bulk spice arrives with its supplier's lot, and buyers often ask for a certificate of analysis showing it was treated or tested for pathogens, since spices are often eaten without cooking. And mixing: a blend that isn't mixed long enough puts all the salt in the first jars and all the cumin in the last. Filling by weight, checked on a scale, keeps every jar at its label weight. Allergens come from the recipe: sesame is one, and so are wheat or milk in some seasonings. In the example below, a Santa Fe spice maker runs 400 jars of taco seasoning.

The short version

  • Eight steps: receive, store, weigh, mix, sift, fill by weight, seal and label, code.
  • Receive each bulk spice with its lot; buyers often want a certificate of analysis for pathogen treatment or testing.
  • Store dry, sealed and off the floor.
  • Weigh by recipe; mix long enough that every jar gets the same blend.
  • Sift out lumps and foreign matter before filling.
  • Fill by weight to the label; code every jar.
  • TaroStack records each blend as a batch with its spice lots, and where the jars went. More below.

The eight steps

Step What happens What to record
1. Receive Bulk spices checked, lot recorded, certificate filed Supplier, lot, certificate
2. Store Sealed bins, off the floor, away from moisture
3. Weigh Each spice weighed by the recipe Weights, ingredient lots
4. Mix Blended to the recipe's time Mix time
5. Sift Through a screen for lumps and foreign matter Anything caught
6. Fill Each jar filled to weight Check weights
7. Seal and label Shaker cap, lid, label Labels used
8. Code Lot and best-by on each jar Lot, best-by, jars

What goes on the label is in spice labeling requirements, and the jar costs in how to open a spice shop.

An example: 400 jars of taco seasoning

Cerrillos Road Spice Co., a made-up spice blend maker in Santa Fe, New Mexico, packs taco seasoning in 70 g jars for gift shops and a grocery chain's local shelf. One run:

Step What happened
Receive Chili pepper lot CP-0920 and cumin lot CU-0915, each with a steam-treatment certificate
Weigh 28.6 kg of blend: chili pepper, salt, cumin, garlic powder, paprika, onion powder, oregano
Mix 15 minutes in a ribbon blender
Sift One small stone caught on the screen, noted against the cumin lot
Fill 400 jars at 70 g, every twentieth weighed: 70 to 72 g
Code Lot TS-1018, best by Oct 2028

The 28.6 kg covered 400 jars of 70 g, 28 kg, plus what the blender and filler hold back. The stone went into the notes and a message to the cumin supplier, with the lot number. The jars' labels read "Chili pepper, salt, spices, garlic powder, paprika, onion powder", as worked out in the labeling article. What the shop orders and when is in order accuracy formula.

Get the run sheet

Download the spice production run sheet. Two sheets: a blank run sheet to print for each batch, with the eight steps, the check at each and its target, and spaces for the actual reading, the time and initials; and the same run filled in from the example. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.

Where this stops working

One run fits on a sheet. Four blends that share chili and cumin, from several supplier lots, mean a question about one cumin lot runs through every blend that used it.

How TaroStack does it

TaroStack records each blend as a batch with its spice lots, and where the jars went.

Receiving with lots. Each bulk spice is received with its supplier's lot, and fields of your own on the lot can hold its certificate number.

Batches from the recipe. A run of taco seasoning takes chili, cumin, salt and jars off stock by the recipe, recording the lots it used.

Where it went. Each shop's order records the lots it got, so one recall report runs from the cumin lot to every shop.

The job Binder In TaroStack
A spice lot's certificate A folder A field on the lot
Which cumin went into a run Written, maybe Lots on the batch
Which shops got a lot Invoices One recall report
What a jar costs A guess True cost from the recipe and batch

Questions people also ask

How are spice blends made commercially?

Bulk spices are received and checked, weighed by the recipe, mixed in a blender, sifted, filled into jars by weight, sealed, labeled and coded.

Do spices need to be treated for bacteria?

Spices are often eaten without cooking, so buyers commonly ask for a supplier's certificate showing the spice was treated or tested; ask your suppliers and your buyers what they need.

How long should a spice blend be mixed?

Long enough that every jar gets the same blend; the time depends on the blender and the batch, so test it and write it on the recipe.

How do I fill spice jars accurately?

Fill by weight and check jars on a scale through the run, so each one meets its label weight.
