Challenges when developing high-protein yogurt

Formulators frequently struggle with producing higher protein yogurts without a gritty or grainy mouthfeel and chalkiness. Our IdaPlus 1085 milk protein solves this dilemma with reduced calcium phosphate content, which opens up the structure of casein micelles, allowing for quicker dispersion and hydration. The dispersion of the proteins significantly reduces any graininess or chalkiness typically…

MPC that works best in yogurt applications

Our new IdaPlus 1085 is a functional protein that works extremely well in Greek-style and traditional yogurt applications where stronger gel set and less syneresis is desired. Due to proprietary processing, IdaPlus 1085 provides more serum phase casein than a standard MPC. The serum phase casein interacts with whey proteins better than casein micelles, which…

Type of MPC that works best in drinking yogurt

Our new IdaPlus 1085 is a functional protein that works extremely well in drinking yogurt applications. In drinking yogurts, even at higher protein levels, it delivers lower viscosity than standard MPCs and maintains it over the shelf life of the product. A reduction of calcium phosphate in IdaPlus 1085 decreases the number of casein interactions…

How does heat stability compare in MPC/MPI vs WPC/WPI?

WPC is much less heat stable than MPC. When WPC is heated under ultra-high temperatures or retort conditions, the native whey unfolds and aggregates, causing gelling. Whey proteins also denature and lose solubility when exposed to ultra-high temperatures. As a result, WPCs cannot be used in large amounts in applications where a high heat step…

MPC/MPI and WPC/WPI flavor differences

MPCs/MPIs have a clean, light, milky flavor compared to WPCs/WPIs. As WPC/WPIs are a byproduct of cheese production, they can have various off-flavors due to processing such as sourness, bitterness, and broth-like. These off-flavors result from high usage levels of sodium, potassium, and chlorine. Whey proteins may also bind volatile flavor compounds during processing. In…

MPC and WPC vs. Ready-to-Drink applications

For purposes of this discussion, ready-to-drink (RTD) beverages will refer to that group of protein-fortified beverages that are shelf stable, i.e., do not require refrigeration for storage and transportation. RTD beverages all have one thing in common no matter how they have been processed. Microbiological assays on RTD beverages yield values of zero or none…

How does MPC eliminate acid whey waste?

High-protein or Greek-style yogurt made with MPC eliminates acid whey waste by straining skim milk solids before making yogurt and eliminating the need for a second straining step that generates acid whey after the yogurt is manufactured. When used at the optimal levels, the water binding properties and flavor attributes of MPC result in creamy,…

What is Acid Whey?

Acid whey is a byproduct of making acid types of dairy products including high-protein or Greek-style yogurts made with a centrifuge method. In order to concentrate the yogurt, the whey is “strained” off. While acid whey can be used in limited quantities in many applications including animal feed and fertilizer, the quantity produced by many…

Yogurt Flavor: WPC vs. MPC

We can definitely say that MPC will contribute to a more realistic milky and yogurt flavor than will WPC. Whey proteins are not primary to yogurt…in authentic, old fashioned 3.2% protein yogurt without stabilizers, the whey proteins are present only at a level of 0.58% while casein is present in the yogurt at a level…

What ratio of MPC and WPC is best for Greek-style yogurt?

It depends entirely on the desired yogurt protein content. We would recommend: 6.4% Protein Greek-style yogurt: 3.2% protein from the yogurt milk, 3.2% protein from MPC or an MPC/WPC blend. 100% MPC or a 90% MPC/10% WPC blend. 7.0% Protein Greek-style yogurt: 3.2% protein from the yogurt milk, 3.0% milk protein from MPC, and 0.8%…
