From application conditions to a purchasing specification
In an oat-based drink, the oat base provides body while the tea ingredient contributes tea flavor and color. Our ingredient selection focuses on tea extracts, fruit-derived powders and botanical sweeteners; the plant-milk base and its emulsifier–stabilizer system are separate formulation choices.
For a green tea oat latte, dissolve a soluble tea extract separately rather than treating it as leaf powder. Compare with a base-only control at the actual protein, salt and pH levels, then check sandy texture, sediment redispersibility and heat-induced flocculation after processing and storage. Goji juice powder follows a different route: a fruit-flavored drink mix, with carrier, reconstitution and color checks rather than a plant-milk base.
Green tea oat latte: ingredient roles and trial sequence →For a beverage containing oil-based flavor or color, quillaja offers a different botanical function from taste, sweetness or an active-ingredient claim: its saponins can provide emulsifying and foaming functions.[1] Start a sourcing discussion with the job the ingredient must do—disperse an oil phase, create foam, or both—not simply “quillaja powder.”
JECFA’s 2005 technical assessment describes Type 1 extracts at 10–30% saponins on a dried basis and Type 2 at 65–90% on a dried basis.[1] It describes Type 2 as further purified by chromatography or ultrafiltration to reduce non-saponin soluble solids such as polyphenols and tannins.[1] These are historical material descriptions, not the guaranteed assay of a current supplier’s finished preparation.
For an oil-flavor emulsion project, include a food-use Type 2 grade in the sample discussion where reduced non-saponin solids are relevant. Do not reject a Type 1 grade solely because its saponin percentage is lower: ask for application evidence from the proposed grade. Neither the type name nor the assay establishes a universal dose, clarity result or shelf life.
| Sourcing choice | What it changes | Practical selection decision |
|---|---|---|
| Type 1 versus Type 2 | Purification and saponin concentration, rather than the physical delivery form.[1] | Specify the intended emulsifying or foaming function, then compare named grades in the actual beverage. |
| Liquid versus spray-dried powder | The assessment describes concentrate sold as liquid or spray-dried powder.[1] | Consider liquid for a liquid-dosing workflow; consider powder for a dry premix workflow. Obtain preparation instructions rather than assuming either is immediately interchangeable. |
| Extract versus standardized preparation | Food-use extracts may be diluted with lactose, maltodextrin or maltitol; preservatives may also be present.[1] | Ask for the full composition and the assay of the product as supplied, not just a percentage quoted for the underlying extract. |
The same assessment describes possible egg-albumin processing aids and lactose carriers.[1] This does not establish that any particular current product contains egg or milk residues. It does mean that botanical origin alone is insufficient evidence for a vegan or allergen-related claim. Obtain a grade-specific ingredient declaration, processing-aid information and relevant allergen documentation before making that claim.
For liquids, request solids, saponin assay basis and preservative information. For powders, request carrier identity and level, moisture and saponin assay basis. Where a dry-basis assay is supplied, ask the supplier to state the corresponding as-supplied content before comparing doses or prices. Total solids should not be used as a substitute for measured saponins.
Send the oil or flavor identity, oil loading in the emulsion and final drink, beverage pH, carbonation, desired appearance, available homogenization process and destination market. Define an acceptable foam level as well as the appearance target. Agree which sample is being supplied: an emulsifier ingredient or a prepared flavor emulsion.
Quillaja-based beverage emulsifiers are a real commercial category: Ingredion describes its Q-NATURALE range for weighted and non-weighted beverages, including clear beverages.[2] That establishes an application route, not equivalent performance from every quillaja extract. Compare the proposed grade in the intended formula and process; do not transfer another manufacturer’s shelf-life, particle-size or certification claims.
Before purchasing, confirm the applicable food category, permitted function, use conditions and labeling requirements for the destination market. A historical technical assessment is not a current authorization for every beverage. Share the application brief for a project-specific sourcing review; grade availability, documentation and suitability require confirmation.
Start with the product format and problem; the ingredient specification can be undecided. These candidates connect our material selection to existing formulation trial concepts. Evaluate samples in your actual formula.
Green Tea Extract · Soluble tea extract
Tea flavour, astringency, haze and sediment decide beverage fit. Evaluate the selected sample in your water, acid and heat process; concentrated EGCG exposure requires a separate safety review.
Stevia Glycoside Extract · Reb D / Reb M glycoside options
Separate stevia bitter aftertaste from lingering sweetness: record the non-sweet note and how long sweetness persists rather than giving one aftertaste score. Compare the glycoside profile and carrier of candidate materials in the same acid, flavor and sweetness target, then repeat the sensory comparison after processing and storage.
Green Tea Extract · Soluble tea extract
Select a flavor-led soluble tea extract for the project’s chosen oat base. Compare tea character, catechin profile, caffeine and carrier composition; a catechin-enriched powder is not a like-for-like flavor substitute. Use the oat-latte trial to compare separate dissolution, sandy texture and heat-induced flocculation in the actual base.
Goji Berry Extract · Juice-derived powder
Goji juice powder provides fruit flavor and color; it is distinct from whole-fruit powder and polysaccharide-enriched fractions. Count the declared drying carrier in the solids balance. Test cool and warm water reconstitution at the intended serving dilution, checking lumps, sediment, color and packed storage.
This pathway covers ingredient and application needs. Finished-product development, testing and manufacturing executors and scope require separate agreement.
Need to develop a beverage concept? →Evaluate botanical ingredients in the actual beverage, not just in water. Clarity, taste and storage behavior depend on the complete formula and process.
Compare dissolution and dispersion at your target pH, water hardness and use level. Check the influence of carrier, filtration and mixing order before changing the ingredient.
Record bitterness as a taste separately from astringency, the drying or puckering mouthfeel. Compare green tea extract samples and use levels in the same water, acid and sweetener system so a base change is not mistaken for a material difference. Recheck both sensory attributes and color after heat treatment and during storage in the intended package.
