What temperature kills probiotics in yogurt?
The bacteria used in making yogurt are thermophilic and this is their optimal temperature range; they are killed above 130°F and do not grow well below 98°F.
How long does unrefrigerated yogurt last?
The United States Food and Drug Administration inspects other foods. Yogurt can be stored in the refrigerator (40 ºF) one to two weeks or frozen (0 ºF) for one to two months. Soft cheeses such as cottage cheese, ricotta or Brie can be refrigerated one week but they don’t freeze well.
How hot is too hot for yoghurt?
The bacteria that ferment milk into yogurt are typically (there are exceptions) thermophilic bacteria, active at elevated temperatures. Therefore, to make nice thick yogurt you must incubate it, maintaining it in a temperature range between 110° and 115°F/43° and 46°C.
What temp kills yogurt starter?
The healthy bacteria in yogurt will die if exposed to temperatures above 130 F (54.4 C).

- Heat the milk to 180 F to denature the proteins.
- Cool to 110 F.
- Add the starter.

What temperature to set yogurt?
Keep the yogurt as close to 100°F (38°C) as possible and undisturbed, to bacterial growth. Some ovens have a “proof” setting that you can use. Other ideas include setting the yogurt on a heating mat (being sure to check the temperature) or placing the containers in a warm water bath.
What temperature is safe for yogurt?
Yogurt should be stored in the refrigerator at 40 °F or below. Additionally, it is important to not let yogurt sit around at room temperature for too long.
What’s the best temperature for yogurt to ferment?
The bacteria that ferment milk into yogurt are typically (there are exceptions) thermophilic bacteria, active at elevated temperatures. Therefore, to make nice thick yogurt you must incubate it, maintaining it in a temperature range between 110° and 115°F/43° and 46°C.
What temperature does yogurt bacteria die?
If bacteria were added to yogurt while it was still hot, they would die. This is because the probiotic bacteria in yogurt are killed at temperatures above 130 F (54.4 C). They are consequently added only after the yogurt has cooled, then are allowed to ferment the product for four to seven hours.
