Liquid rennet
A liquid milk-coagulating enzyme preparation whose source, activity and formulation vary, used to form curd for cheesemaking.
Traditional method
Tulum peyniri
Tulum peyniri is a Turkish cheese traditionally packed into animal-skin bags to mature. This sheep-milk method adds a thermophilic yogurt culture before renneting, draining and dry salting.

Tulum peyniri takes its name from the skin bag in which the cheese matures. It belongs to a varied Turkish tradition: milk, curd treatment, salting, packaging and ripening differ between regions. Skin bags have increasingly given way to drums and tins where their preparation is difficult. The yogurt-cultured method here uses goatskin for a cold maturation.

Fresh cheeses can carry Salmonella, pathogenic E. coli, Listeria monocytogenes, or Staphylococcus aureus; handling after heating can reintroduce contamination.
Hazard sourceAnimal-skin packaging must be free of zoonotic infection and must not contaminate the cheese with heavy metals or foreign matter.
Hazard sourceUse pasteurized milk for home cheesemaking, sanitize contact surfaces and equipment, wash hands and handle and cool curds hygienically.
Control sourceUse a clean, dry skin free of zoonotic infection and contaminants.
Control sourceRaw milk can carry pathogens; use pasteurized milk for home cheesemaking. Wash hands, sanitize equipment and contact surfaces, and prevent contamination during curd handling and cooling.
Skin bags can introduce contamination. Use skins free of zoonotic infection, clean and dry, and prepared so that heavy metals and foreign matter cannot contaminate the cheese.
Thermophilic yogurt culture — Starter added at the reported 1% rate; source does not identify species or strains.
Anaerobic maturation in a goatskin bag at 6–8°C for 90–120 days; humidity is not stated.
