Egg Yolk Powder

Procurement Specification Snapshot

Use this summary for initial product screening. Final composition, analytical limits, and lot-specific results should be confirmed against the approved specification and certificate of analysis (COA).

Choosing the Right Egg Yolk Powder

Select the grade according to process conditions and the flavor profile required in the finished product.

Standard Egg Yolk Powder

Best for broad functional use where natural yolk emulsification, golden color, richness, and binding are required. Typical applications include sauces, condiments, mayonnaise, bakery, pasta, custards, frozen desserts, and lecithin extraction. Shelf life: 18 months. Packaging: 20 kg / 25 kg.

Salted Heat-Stable Egg Yolk Powder

Choose this grade for mayonnaise and salad dressings that require better tolerance to higher processing temperatures. It has a savory profile and excellent heat stability. Shelf life: 24 months. Packaging: 20 kg.

Salted Egg Yolk Powder

Choose this flavor-forward grade when a rich savory salted-yolk taste is the main requirement rather than neutral functionality. Typical uses include baked desserts, snack seasoning, foodservice flavoring, buns, cookies, prawns, chicken, and fried rice. Shelf life: 12 months. Packaging: 2 kg / 5 kg / 20 kg.

How to Reconstitute Egg Yolk Powder

Egg yolk powder is a spray-dried ingredient that rehydrates easily into liquid egg yolk for use in bakery, sauces, mayonnaise, pasta, custards, and infant nutrition. Proper reconstitution preserves the natural emulsifying, coloring, and binding properties of fresh yolk.

Standard Reconstitution Ratio (1 : 1.17 by weight)

Directions：

1. Measure cool or lukewarm water (below 40°C). Avoid hot water, as excessive heat may denature the lipoproteins and weaken emulsifying performance.

2. Sprinkle the powder gradually into the water while stirring continuously to ensure an even dispersion and prevent lumping.

3. Rest the mixture for 20–30 minutes to allow the fat and protein components to fully rehydrate.

4. Blend or whisk briefly before use. For emulsion-based applications such as mayonnaise or hollandaise, a high-shear mixer produces the smoothest, most stable texture.

Functional Properties of Spray-Dried Egg Yolk Powder

Egg yolk powder is not simply “dehydrated egg” — it is a multifunctional ingredient whose performance in finished products derives from three preserved native properties of fresh yolk:

1. Emulsification (lecithin and lipoprotein content)

Egg yolk contains 9–10% lecithin and a high concentration of lipoproteins (LDL/HDL) that stabilize oil-in-water emulsions. In mayonnaise, salad dressing, hollandaise, and Caesar dressing applications, reconstituted yolk powder delivers the same emulsion stability as fresh yolk when properly rehydrated below 40 °C. This is why rehydration temperature control matters: heat-denatured lipoproteins lose emulsifying performance and produce broken, oil-separating finished products.

2. Color contribution

Natural carotenoids (lutein, zeaxanthin) deliver the golden-yellow color signature essential to fresh pasta, custards, sponge cakes, lemon curd, and ice cream — without synthetic colorants. Color intensity is consistent batch-to-batch through controlled feed-stock management.

3. Richness, mouthfeel, and binding

The 60%+ lipid content of yolk delivers fat-based mouthfeel, flavor carrier function, and protein-based binding in baked goods, sauces, and frozen desserts. In ice cream and gelato, yolk powder contributes the silky, slow-melting texture of premium custard-base (gelato all’uovo) products.
