Whey butter: a promising perspective for the dairy industry

Manteiga de soro de queijo: uma perspectiva promissora para as indústrias lácteas

Abstract

Cheese whey is the main by-product obtained in the production of cheese. Despite its high nutritional value, approximately half of the whey volume generated is still disposed incorrectly, which causes damage to the ecosystem due to the high cheese whey pollutant load. Therefore, it is important to use this by-product and its components in an increasing number of applications, especially as food ingredient. This review aimed to show the technology of production of butter from whey cream, as well as showing the physico-chemical, sensory, and nutritional characteristics of the product. There were no significant variations in the physico-chemical composition of milk cream butter and whey cream butter in the literature available. As the technology to produce whey butter is quite simple, this by-product has potential to be exploited by the dairy industry. Additionally, further studies on production process, characterization, and sensory analysis are required to enable its large-scale production.

HIGHLIGHTS

Butter obtained from cheese whey had a good nutritional composition

Whey cream butter is characterized by high concentration of unsaturated fatty acids

Shelf-life of whey cream butter is reduced due to oxidation of unsaturated fatty acids
