Why does the milk have to be boiled to make yogurt?

The biggest reason to heat milk to almost boiling before fermenting is that it improves the texture of the yogurt. During fermentation the bacteria consume lactose and produce lactic acid which causes the milk proteins to denature and coagulate trapping most of the fat.

How long should yogurt ferment?

If you want a less tangy or thick yogurt, ferment for around 8 hours. For a thick, tangy, and probiotic-rich yogurt, go closer to 24 hours. After 24 hours, you start to hit the law of diminishing returns—you begin to get bacterial die-off because the more aggressive bacteria start to beat out the other probiotics.

What happens if I cook yoghurt?

Most bacteria will die when heated past a certain temperature. Yogurt is made by heating, cooling and then fermenting milk using healthy streptococcus and lactobacillus bacteria. The final product can be consumed hot or cold. However, if heated past a certain point, the bacteria in yogurt will die.

Does yogurt curdle when heated?

Yogurt curdles when the protein strands congeal, or tighten up, when they are exposed to heat. … If you add a nonfat or low-fat yogurt to a simmering sauce, it will curdle more easily than the full-fat version because it does not have as much fat to protect the proteins from the heat of the sauce.
