Taste the flavor of science with UPLB’s salted duck egg powder

Salted egg is a flavor that is easy to fall in love with. Despite the suggestion in its name, it lets the tongue experience more than a single note of saltiness and provides a buttery-rich-like satisfaction. 

It is not a surprise that many delicacies now come in salted egg flavors. Salted egg-flavored finger foods such as chips, popcorn, noodles, and fish skins have already become a trend. Meanwhile, fried dishes (i.e. pork, fish, chicken) can be enriched with a salted egg glaze’s salty and creamy goodness

With a promising market, the innovation of a salted duck egg powder from the University of the Philippines Los Baños (UPLB), supported by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD), can provide opportunities for agribusinesses to take advantage of the demand for salted egg flavoring. In the country, salted-egg products are usually made from duck eggs. According to UPLB experts, the salted duck egg powder has a better taste and texture and provides more nutritional value compared with similar chicken egg-based products.

How is salted duck egg powder made?

Salted duck egg powder can be produced by cabinet-drying or spray-drying, among other methods. To dry salted duck eggs in both processes, the eggs are scrambled before putting it inside the dryer.

In a cabinet-drying process, the salted duck egg is dried using heat and dry air inside an oven for some time depending on the amount. Once completely dry, the dried salted duck egg will be food-processed to become powder. Because cabinet dryers are relatively cheap, this technique is usually suggested to micro-, small, and medium enterprises.

In spray-drying, the eggs are sprayed inside a drying chamber.  Spraying can form droplets of eggs, which are subsequently dried and accummulated in a powder form.  Spray-dried salted duck egg powders are lighter in color and have finer particles than cabinet-dried powders. This method can be used for medium to large-scale production of salted duck egg powders.
