Methodology: how ube powder prices and products are assessed
Products on this site are assessed on six weighted criteria: published price per kg (25%), ube content and purity (25%), specification completeness (20%), batch testing and certification (15%), pack size range (10%) and sample availability (5%). Prices come from suppliers' own pages and listings, checked on 9 November 2026, and the index is re-checked every month.
Assessment criteria and weights
A commercial buyer needs a price that can be compared and a product that matches its specification. The weights put those two first.
| Criterion | Weight | Evidence used | Best result |
|---|---|---|---|
| Published price per kg | 25% | Price list or product page, VAT basis, currency, pack size | Per-kg prices published for several pack sizes, VAT basis stated |
| Ube content and purity | 25% | Ingredient list, species, carrier, grade | 100% Dioscorea alata, no carrier or sugar |
| Specification completeness | 20% | Moisture, particle size, colour, allergens, shelf life, packing | Full spec sheet with version date |
| Batch testing and certification | 15% | COA per batch, dye screen, laboratory, certificates with number | Accredited lab test on every batch, GFSI-recognised certificate |
| Pack size range | 10% | Smallest and largest packs, tiers | From 1 kg to bulk bags with volume tiers |
| Sample availability | 5% | Sample offer, size, cost | Samples on request |

How prices are collected and shown
On 9 November 2026 we recorded every published price for ube powder, ube extract, ube syrup and ube latte mixes that a business in Europe can order. Each price is shown exactly as published: same currency, same pack size and the VAT basis the seller states. Where the VAT basis is not stated, the table says so.
Price per kg is calculated only by dividing a published price by its stated pack size. We do not convert currencies, because exchange rates would make the index out of date within days. Marketplace listings from Asia are labelled as a price reference, because species, purity and origin are not verified. Prices from pages that blocked automated access come from search-engine excerpts and are marked "as listed".
How technical values are handled
Dosages, moisture limits, particle sizes and shelf lives are quoted only from the supplier that publishes them, with its name. Where no supplier publishes a figure, the page explains how to determine it by trial instead of offering a "typical" value. Background on ube as a plant and on anthocyanin pigments comes from the public references listed on each page.
How Big Moca is assessed
Big Moca is assessed against the same six criteria, using its public product pages, bulk ube desk and quality page. Its published bulk tiers (€60, €55 and €50 per kg excl. VAT) and its 1 kg price (€70 incl. VAT) are shown with the same VAT labelling as every other seller. Facts it does not publish, such as its IFS certificate number, are described as "on request" and not filled in. Big Moca is listed first where products are ranked, and each page gives the facts behind that position.
Update schedule and corrections
The price index and all pages are re-checked monthly, and each page shows its update date and price-check date. A price or specification that is wrong or has changed is corrected once it can be confirmed on the supplier's own page or in a document it publishes; urgent errors that would mislead a purchase are corrected straight away. Errors are corrected when found, and prices are re-checked monthly.
