Purple Yam Powder

Purple Yam Powder — Natural Ube Ingredient for Food & Nutraceutical Applications

Purple yam powder is made from dried purple yams. It is possible to treat the tubers with low-temperature spray drying or freeze drying to keep their original nutritional value, bright violet color, and nutty-vanilla taste. The particles stay between 60 and 120 mesh, and the moisture level stays below 6%.

This way, you can be sure that each batch will have the same color and taste.To make supplements and foods, it gives them a uniform source of anthocyanins and resistant starch that they can store.

Product Overview

You can only get fresh yam at certain times of the year, and the color isn't always even. It comes in a standard, shelf-stable form that can be used in commercial cooking. Purple Yam Powder, on the other hand, is not. Natural anthocyanin gives the fruit a safe color that can be used instead of dyes made in a lab. The starch part gives baked goods and drinks structure.

Key characteristics include:

• Natural clean-label colorant — an alternative to synthetic Red No. 40 and Blue No. 1
• Consistent organoleptic profile — standardized flavor and color intensity across batches
• pH-sensitive pigment — shifts toward blue in alkaline environments; manageable with acid balance
• Moisture-controlled stability — below 6% moisture supports hygroscopic stability during storage

Application Areas

Bakery & Confectionery

The natural starch in the flour helps the dough get thick and gives the bread its shape. Usually, 3–5% of the whole dose is used for color and 10–15% is used for full taste.

Beverages & Bubble Tea

High pressure or warm water makes spray-dried grade easy to spread out. Purple Yam Powder adds color and texture to RTD drinks, milkshakes, and smoothies.

Nutraceuticals & Supplements

Potassium, iron, resistant starch, and fiber are all in it. Anthocyanins keep their shape when pills are made regularly.

Desserts & Plant-Based Foods

It can be used to add natural color to ice cream, puddings, and veggie foods that don't need any extra chemicals.

Frequently Asked Questions

Q:What changes the color of my batter from yellow to green or blue?

A:It is normal for anthocyanins to show what the pH level is. Acidic things, like baking soda, make things change color. You can use baking powder or lemon juice or cream of tartar to keep the purple color.

Q2: What dose should I use for production?

A:For color comparison, 4% by flour weight is often used as a starting point. Color sharpness can be dulled by fat, so changes may need to be made. 10 to 15 percent is a common range for flavoring.

Q:How do i stop it from cuffing up while storing it?

A:Dry things out in bags sealed with aluminum foil and keep them somewhere below 25°C and 60% RH. Most of the time, soft clumps that are easy to break apart are fine. Hard clumps are a sign of moisture intrusion and should be tested for right away.

Q4: Does cold water break it down?

A:For full dispersion, standard spray-dried powder needs to be mixed with warm water or high shear. For uses that need to dissolve in cold water, a pre-gelatinized choice may be available. Please Contact Us to talk about your recipe needs.

Q5: What makes it different from Taro Powder?

A:Purple Yam (Ube), which comes from Dioscorea alata, has a darker violet color and a taste that is similar to vanilla and nuts. Taro (Colocasia) has a lighter color and a mild, starchy flavor. The two need to be processed in different ways and cannot be used in place of each other in creation.
