Getting the dried whey protein concentrate and its effect on pan bread evaluation

Abstract EN

The aim of study is to obtain dried whey protein concentrate and to study the functional properties and physical, chemical properties.

It was incorporated into pan bread made using different levels of dried whey protein concentrate.

Pan bread samples were analyzed for sensory, physical and chemical attributes.

The results revealed that sweet cheese whey contain 93.14% water, 4.85% lactose, 0.7% soluble protein, 0.11% fat and 0.9% ash contents.

While, the produced dried whey protein concentrate contained 7.04% water 92.96% total solids, 10.47% lactose, 66.87% protein, 3.65% fat and 5.63% ash contents and contained higher levels of essential amino acids especially lysine, threonine and valine.

Functional properties of dried whey protein concentrate were 4.8% , 2.2% , 50% , 80% and 0.52 g/cm³ for water orption capacity, oil orption capacity, foam capacity, foam stability and bulk density, respectively.

Sensory, physical and chemical evaluation revealed that pan bread made using 20% dried whey protein concentrate had the best quality compared with control and other levels of dried whey protein concentrate.
