Where Roxburgh rose (cili fruit) powder earns its place in a formula
The three questions we ask before recommending a cili fruit grade. Most enquiries arrive with a finished product in mind, a sachet, a bottled drink, a gummy, and the right grade follows from the format. Before quoting we ask whether the label carries a vitamin C claim, which format the powder goes into, and whether a carrier is acceptable, because a vitamin C claim sits differently on a carrier-free powder than on a diluted one. We then suggest starting with the standard 80 mesh, carrier-free grade from a production lot, and moving to 100 mesh or a maltodextrin carrier only if the format needs it. If the buyer sends the label claim and the target market, we recommend the grade our other buyers in the same category use, usually within one email.
The Roxburgh rose (cili fruit) powder product page lists four application areas, and almost every enquiry we see lands in one of them. What changes between them is not the material but two specification choices, carrier and mesh, and the way a pilot should be run. This article covers each format and the questions to settle before a formula is locked. The buying mechanics behind these choices — what a quotation actually covers and how a first order is structured — are covered in our Roxburgh rose (cili fruit) sourcing guide.
Immunity-support blends
This is the material’s home: multi-ingredient powder and capsule formulas where the fruit’s native vitamin C supports the positioning. The standard grade is carrier-free, 100% cili fruit solids, which is what clean-label immunity positioning needs. A maltodextrin carrier is available on request, but it dilutes any native vitamin C content on the finished label, so the carrier decision belongs to the marketing claim as much as to the process. For capsules the standard 80 mesh is adequate; for stick packs and sachets, 100 mesh on request is usually the better conversation.
Roxburgh rose powder in functional beverages
The tangy, fruity character carries well in dilution, and the low-temperature spray-drying process is what keeps it there. Two practical notes from beverage work:
- Clarity. For a clear bottled drink, plan a filtration or clarification step, because a fruit powder will otherwise leave a fine sediment that reads as a defect on shelf.
- Trial strength. A sample spooned dry tells you nothing about how the flavour carries in the finished dilution. Trial at serving strength, not at powder strength.
For ready-to-drink formats the standard 80 mesh disperses adequately in a bottling line’s mixing step; the finer 100 mesh is usually reserved for dry sachet and stick-pack formats where a visible particle is a complaint.
Gummies and lozenges
A fine fruit powder at 80 mesh, or 100 mesh on request, blends into a pectin or gelatin matrix without grittiness at standard doses. Gummies are also the format where the carrier decision is most visible: carrier-free keeps the vitamin C claim honest on the label, while a carrier changes flow behaviour and cost per kilo. If the gummy states a vitamin C figure, run the trial on the carrier-free grade first.
Superfruit powder mixes
Sold on its own or in blends with other berry and fruit powders, where the light beige-to-cream colour and mild, tangy taste keep the mix usable. This is the format where mesh matters least and documentation matters most, because the mix is usually sold on the ingredient list and the COA rather than on any potency figure. Ask for the batch COA with the blend documentation, the same way you would for the single-ingredient product.
Running a pilot before committing
Samples are drawn from production lots rather than made separately, so the material you trial is the material that would ship. How much we can supply free of charge depends on the item’s value; anything beyond that is billed at cost plus courier and quoted up front. In practice the right first step is a 1 kg or 5 kg foil bag of the standard grade, trialed at serving strength in the finished format, with the specification sheet and a sample COA alongside. In-stock items are ready in about 2 days, so a pilot does not need to sit on the critical path of a formula launch.
Trial the standard 80 mesh, carrier-free grade first. Move to 100 mesh or a maltodextrin carrier only when the format shows you it needs one.
Frequently asked questions
What is Roxburgh rose powder used for?
The product page lists four application areas: immunity-support blends, functional beverages, gummies and lozenges, and superfruit powder mixes. Most formulas we see sit in the first two, usually as a vitamin C carrier in multi-ingredient immunity products.
Which mesh size should I choose for my format?
80 mesh is standard and disperses adequately for beverage mixing and capsules; 100 mesh on request is usually worth the conversation for sachets, stick packs and gummies, where fine dispersion avoids grittiness in the finished product.
How do I run a formula trial?
Ask for a 1 kg or 5 kg foil bag drawn from a production lot, so you test the material that would ship. Samples are always drawn from production lots; the free quantity depends on the item's value and anything beyond is billed at cost plus courier, quoted up front. MOQ is 1 kg.
