Milk protein concentrates: opportunities and challenges

Area of Science:

• Food Science
• Dairy Science
• Protein Chemistry

Background:

• Milk protein concentrates (MPCs) have limited applications due to poor solubility compared to casein and whey proteins.
• Solubility is a critical functional property of MPCs, influencing their use in food products.
• Ambiguity in the definition and manufacturing of MPCs exists in scientific literature.

Purpose of the Study:

• To clarify the definition and manufacturing of MPCs.
• To review the mechanisms and factors influencing MPC insolubility.
• To explore novel strategies for enhancing MPC heat stability and solubility.

Main Methods:

• Literature review on MPC properties and manufacturing.
• Analysis of factors affecting protein solubility and heat stability.
• Examination of recent advancements in improving MPC functionality.

Main Results:

• Insolubility of MPCs is influenced by processing and protein content.
• Several strategies are emerging to enhance MPC heat stability and solubility.
• Improved solubility can unlock new applications for MPCs as food ingredients.

Conclusions:

• Addressing MPC solubility challenges is crucial for expanding their use in the food industry.
• Understanding the factors affecting solubility aids in developing improved processing techniques.
• Novel strategies show promise for utilizing MPCs as versatile food ingredients.
