Understanding pH dynamics in cheesemaking: insights across different cheese varieties.

Area of Science:

• Food Science
• Dairy Chemistry
• Microbiology

Background:

• pH is a critical factor in cheesemaking, influencing physicochemical and microbiological processes from curd formation to ripening.
• It affects enzyme activity, microbial growth, protein structure, and mineral solubility, impacting cheese texture, safety, and sensory attributes.
• Key functional properties like meltability, stretchability, and water holding capacity are governed by pH-dependent interactions.

Purpose of the Study:

• To review current research on how pH influences the structural and functional properties of various cheese types.
• To examine the relationship between pH-induced protein matrix changes and cheese functionality.
• To provide insights for tailoring cheese characteristics and developing predictive quality models.

Main Methods:

• Literature review of scientific research on pH in cheesemaking.
• Analysis of pH effects on protein structure, enzymatic activity, and microbial dynamics.
• Examination of pH-related functional properties in major cheese varieties.

Main Results:

• pH significantly affects protein matrix structure, influencing cheese texture and functional properties.
• Microbial growth and enzymatic activity are highly pH-dependent, impacting flavor development and safety.
• Specific pH ranges are critical for achieving desired characteristics in different cheese types like Cheddar, Mozzarella, and processed cheese.

Conclusions:

• pH is an essential control parameter in cheesemaking, directly impacting cheese quality and functionality.
• Understanding pH-structure-function relationships enables targeted cheese design and process optimization.
• Precise pH control can enhance consistency, product quality, and innovation in the dairy industry.
