★Does Casein Phosphopeptides help with calcium absorption?
Casein Phosphopeptides (CPP) are phosphorylated peptides derived from casein and have the ability to bind calcium. Research has investigated their potential role in maintaining calcium in a soluble form and supporting calcium availability in the intestinal environment. However, results vary depending on the CPP preparation, calcium source, dosage, and food matrix, so CPP should not be described as universally increasing calcium absorption.
★How do Casein Phosphopeptides bind calcium?
CPP contains phosphorylated serine residues and other negatively charged groups that can interact with calcium ions. These interactions can form soluble calcium-peptide complexes and are one of the main mechanisms studied for CPP's mineral-binding properties.
★What is the difference between Casein Phosphopeptides and CPP-Ca?
Casein Phosphopeptides are the peptide ingredient itself, while CPP-Ca generally refers to a calcium-peptide complex formed by combining or chelating CPP with calcium. CPP-Ca can therefore have different calcium content and physicochemical properties from uncomplexed CPP.
★What is the recommended dosage for Casein Phosphopeptides in food and dietary supplements?
Recommended inclusion levels depend on the final application. For functional beverages, infant formulas, and solid supplements, active CPP content typically ranges from 0.1% to 1.0% by weight (or 50 mg to 500 mg per serving), often formulated in a targeted 1:10 to 1:20 ratio with calcium.
★Is Casein Phosphopeptides water-soluble and heat-stable during processing?
Casein Phosphopeptides exhibit excellent water solubility and high thermal stability across a wide pH range. Unlike intact casein, CPP remains fully dissolved without coagulating during standard pasteurization, UHT (Ultra-High Temperature) treatment, or spray drying, making it ideal for liquid dairy, functional beverages, and oral liquids.
