Ube powder for ice cream production

Ube ice cream is one of the classic uses of the purple yam: in the Philippines ube flavours ice cream, flavoured milk and halo-halo, the iced dessert that often contains ube halaya. For a producer, ube adds a violet colour and a mild, sweet, earthy flavour without needing an added colouring when the powder is 100% ube.

Powder works in both dairy and plant-based bases. Big Moca's 100% ube powder is vegan, non-GMO and free of the 14 EU allergens, so it adds nothing to the allergen statement of a dairy-free line.

The choice is between a powder dosed in percent and a liquid dosed in grams per kg. Both are used; they behave very differently in cost, label and composition.

A liquid extract at 0.5–2 g per kg looks cheap per batch, but Royal Brand's ingredients and ube content are not stated on the EU-English page; its Polish page lists sugar, 15% ube extract and invert sugar. With an extract it is hard to tell how much of the colour and flavour comes from ube. With 100% powder, every gram on the label is ube.

No published standard exists for ube powder in ice cream, so dosage comes from a trial. Big Moca gives about 10% of dry weight as a general guide for its powder; it is a starting point, not an ice cream recipe.

Run the trial on your own base:

1. Make three to five batches of the same base with different ube dosages around the guide.
2. Process them exactly as in production, through pasteurising, ageing and freezing.
3. Taste and judge colour at serving temperature, not in the warm mix.
4. Store samples in the display cabinet or freezer you will sell from, and check colour again after a week.

Record the dosage per kg of total mix so cost and label calculations stay simple.

Anthocyanins, the pigments behind ube's colour, change with pH and degrade under light, oxygen and heat. In ice cream the main risks come after production.

• Fruit ripples and sauces. Acidic components push nearby ube towards red. Test combinations side by side.
• Display lighting. Light keeps acting on the pigment in an open cabinet. Compare a lit sample with one stored in the dark.
• Rework and heat abuse. Repeated temperature cycles expose the mix to more heat and oxygen.

A dye-free starting point makes these tests meaningful. Big Moca's batches are tested by Eurofins for synthetic dyes (not detected, below 2 mg/kg per dye), so the colour you see is the ube's own.

Because dosage varies by recipe, calculate cost per 1% of ube powder in the mix: 1% of 1 kg is 10 g. Multiply by your trial dosage.

Ube powder price	Cost per 1% in 1 kg of mix	At 3%	At 5%
€50/kg (100 kg, excl. VAT)	€0.50	€1.50	€2.50
€55/kg (60 kg, excl. VAT)	€0.55	€1.65	€2.75
€60/kg (20 kg bag, excl. VAT)	€0.60	€1.80	€3.00
€70/kg (1 kg pouch, incl. VAT)	€0.70	€2.10	€3.50

The 3% and 5% columns are arithmetic examples, not recommended dosages. Big Moca sells the 20 kg bag through its ube powder wholesale page, and 1 kg pouches for development batches. Every price tier is in the price index.

Before scaling up, ask for the spec sheet and a COA for the batch you will use. For ice cream, check moisture (Big Moca: below 5.0%), particle size (at least 95% through 80 mesh), a microbiological profile and the allergen statement. Ask whether the powder is 100% Dioscorea alata, because purple sweet potato and coloured powders are also sold as "ube". The fields to look for are explained in ube powder specifications.
