Introduction

Microparticulated Whey Proteins include the processing, selling and usage of specific dairy ingredients that are obtained through transformation of whey proteins into micro particles via heat and mechanical force. The small particles are designed to mimic the smooth mouth feel of the fats making them natural fat substitutes while providing protein without additional fats in products such as yoghurt, beverages and ice cream. Microparticulated Whey Proteins (MWP) can be defined as highly processed, functional whey proteins which have been restructured via a concurrent thermal/mechanical process. The advantages of using microparticulated whey protein include enhanced digestion due to better particle uniformity and dispersibility. The high heat stability of microparticulated whey protein ensures that protein functionality remains intact even after the process of pasteurization or thermal processing without aggregation. Controlled particle size ensures good mouthfeel and allows smooth and creamy texture development in high protein ready-to-drink beverages and functional dairy beverages. Moreover, it is highly versatile from a functional perspective and allows increased protein content in low-calorie food and beverages, sports nutrition, and medical nutrition products.
