Turkish yoğurt is milk heated hard, cooled and seeded with yogurt from the previous day or a pure culture, then held at 42–45 °C until it sets. Turkey's food codex defines yoğurt by its two starter bacteria, Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus.

At a glance
Turkish yoğurt is milk heated hard, cooled and seeded with yogurt from the previous day or a pure culture, then held at 42–45 °C until it sets. Turkey's food codex defines yoğurt by its two starter bacteria, Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. Made in 5 steps over 2.5 h – 3.5 h. The longest step, hold warm and let it set, takes 2–3 h (FAO 1990) and runs at 42–45 °C (FAO 1990). Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus do most of the fermenting.
Turkish yoğurt is set from heated milk seeded with the previous day's yogurt or a pure culture (FAO's Near East yoghurt entry, which lists Turkey). Turkish law reserves the name for milk soured by both S. thermophilus and L. bulgaricus, and süzme yoğurt must reach 8 % protein.
Süzme yoğurtStrained yogurt; the codex sets at least 8 % protein, reached by standardising the milk or by removing whey.
Yogurt with a named cream-forming stepThe codex requires production steps such as homogenisation or cream-forming (kaymak) to be named together with the product name.
Safety
The milk is heated before souring, and the finished yogurt is kept below 6 °C, as the codex requires.
FAO's survey says the yoghurt of the Near East originated from central Asian and Mediterranean countries, mainly Turkey, Lebanon, Bulgaria and Romania. The Turkish food codex communiqué 2022/44, published on 30 November 2022, replaced the 2009 fermented milk communiqué.
