Sometimes even small process adjustments can have outsized impact. Something like production costs being cut by 8.8% with a simple temperature change.

Researchers at DTU National Food Institute proved this with yogurt production.

Yogurt production typically struggles with expensive starter cultures that cost about 11% of production, post-acidification sourness, and spoilage yeasts that reduce quality and increase waste.

The DTU team developed a two-step fermentation process that solves these issues through a temperature-controlled approach.

After the initial fermentation phase at 42°C, the temperature is raised to 51°C. Due to the high temperature, bacteria stop multiplying but continue producing lactic acid.

With fewer bacteria actively growing, post-acidification happens 5 to 10 times slower than usual, giving producers better control over acidity and product consistency.

It’s bacterial minimalism at its finest. 🙂

Lab trials showed that this approach:

Reduces starter culture use by 80%, cutting total production costs by 8.8%

Completely eliminates post-acidification

Kills 99.9% of spoilage yeasts and molds, extending shelf life significantly

Requires no new equipment or major process changes

Innovations like DTU’s method show how the dairy industry continues to grow through smarter production techniques.

If you’re interested in where dairy is heading next, my team recently analyzed trends with real consumer traction. We looked at segments like GLP-1 user demands, functional dairy, HMObiotics for infant gut health, and other trends experiencing real growth right now.

These are the trends that won’t “curdle” over time. 🙂
