There is a shade that stops you in your tracks the moment you open the pouch: a deep, almost unreal purple, somewhere between lilac and amethyst. The natural purple colour of ube is probably what makes most food lovers fall for it before the very first mouthful. But where does this spectacular mauve come from? Is it really natural, or should you suspect a hidden dye? At Ubedia we work exclusively with the Kinampay variety, the premium purple yam grown in the Visayas, in the Philippines, known precisely for the intensity of its purple colour. In this guide we explain the science behind the pigment, why the hue can vary from one batch to another, how not to confuse ube's purple with that of taro or sweet potato, and above all how to preserve this purple colour when you cook. You will never look at your mauve latte in quite the same way again.
Where does ube's purple colour come from?
Ube's purple colour owes nothing to chance or to chemistry: it comes from plant pigments called anthocyanins. These are the same compounds that give their hue to blueberries, red cabbage or black grapes. In the purple yam Dioscorea alata, these anthocyanins are particularly concentrated, which explains that dense, luminous mauve, far deeper than that of many other tubers.
The final shade also depends on acidity: in a slightly acidic environment the purple leans towards pink-magenta, while in a neutral one it shifts to blue-violet. That is why the same pouch of powder can give a distinctly mauve latte in a plant-based milk and a bluer cake batter. There is nothing abnormal about it: it is the signature of a colour that is 100% plant-based and alive.
A 100% natural purple colour, with no dye
This is the point that reassures our customers most: the purple colour of Ubedia ube powder contains no dye, no additive, no added colouring agent. What you see is nothing but Kinampay yam, dried and then milled into a fine powder. Our powder is 100% purple yam, a single ingredient, our sourcing is direct from growers in the Visayas, and every batch is traced from the plot to the pouch, through to packing in France, in Aix-en-Provence.
Be wary of powders with a fluorescent, uniform, artificially bright purple: a shade that is too perfect often conceals a dye. Ube's true natural purple is rich, nuanced, and may shift slightly with the harvest. That irregularity is a mark of authenticity, not a flaw.
Why the shade varies from batch to batch
A natural product is never perfectly identical from one season to the next, and that is a good thing. Several factors influence the intensity of ube's purple colour:
- The maturity of the tuber at harvest: a fully ripe yam concentrates more anthocyanins.
- The terroir of the Visayas and the conditions of the growing season.
- The drying: gentle, well-controlled dehydration preserves the pigments better than aggressive drying.
- The pH of your recipe, which tips the shade towards pink or blue.
In other words, if your new pouch looks a little lighter or a little deeper, that is simply nature expressing itself. The quality, for its part, stays constant.
Ube, taro, sweet potato: don't mix up the purples
Many people think they have tasted ube when in fact it was taro or purple sweet potato. These three ingredients display different mauves, and their colour has neither the same origin nor the same intensity.
| Ingredient | Natural colour | Origin of the pigment |
|---|---|---|
| Ube (Kinampay) | Deep purple, intense mauve | Very concentrated anthocyanins |
| Taro | Off-white to pale mauve, veined | Very little purple pigment |
| Purple sweet potato | Darker purple, leaning towards plum | Anthocyanins, a darker shade |
Taro, often sold as "purple", is in fact almost white: the mauve colour of taro desserts frequently comes from a dye. To go further, discover our detailed comparisons Ube vs Taro and Ube vs purple sweet potato, which will spare you plenty of confusion both in the shop and in the kitchen.
How to preserve the purple colour when cooking
Anthocyanins are sensitive to excessive heat and to light. To keep a beautiful purple colour in your preparations, a few habits are enough:
- Stir the powder in towards the end of cooking where possible, rather than boiling it for a long time.
- A touch of acidity (lemon, yoghurt) revives and stabilises the mauve, especially in creams and icings.
- Keep your powder away from light, in an airtight container, to protect the pigments.
- Avoid very long cooking at high temperature, which dulls the shade.
With these simple steps, your latte, your ice cream or your cake will keep that appetising purple that is the whole charm of ube.
