Scalding sausages: temperatures, times and troubleshooting

Sausages are scalded in 75–80 °C hot water; the water must never boil. The target is a core temperature of about 72 °C, while about 68 °C merely marks the beginning of protein coagulation. As a rule of thumb for the duration, allow approximately one minute per millimetre of calibre until the required core temperature is reached in the core of the batch.

We at Beelonia GmbH have been manufacturing kettles for controllable scalding and boiling processes in Beelen since 1880.

Scalding sausages at a glance: what you need to know

Scalded sausage requires controlled, non-boiling water, a suitable scalding time, and a verified core temperature. The general range is 75–80 °C for the water and about 72 °C in the core. The calibre rule of thumb only serves as a guide until a suitable measurement confirms the safe process target.

Process value	Proven guideline	Meaning
Water temperature	75–80 °C	General scalding range; never let the water boil
Target core temperature	About 72 °C	Shelf-life standard
Protein coagulation	Begins at about 68 °C	Not a substitute for the target of about 72 °C
Scalding duration	Approximately 1 minute per millimetre of calibre	Rule of thumb, core temperature remains decisive
After scalding	Quench in ice water	Prepare as a fixed process step

At what temperature are sausages scalded?

Sausages are scalded at a water temperature of 75–80 °C without the water boiling. The target is a core temperature of about 72 °C. For Wiener or Frankfurter sausages in a 22/24 sheep casing, the narrower water range of 75–78 °C should be used, provided the recipe and operational guidelines allow for it.

Application	Water temperature	Target in the core
Scalded sausage in general	75–80 °C	About 72 °C
Wiener/Frankfurter in 22/24 sheep casing	75–78 °C	About 72 °C

Increase the temperature slowly and steadily. Above 80 °C, casings can burst and fat can leak out. The water temperature display does not replace a process-suitable core temperature measurement.

How long are sausages scalded?

The scalding duration depends primarily on the calibre and does not end solely by the clock, but when the process target is reached. As a rule of thumb, allow approximately 1 minute per millimetre of calibre; a 32/34 casing therefore needs a good 30 minutes. Deviations are necessary if the sausage type, starting temperature, or batch require a longer controlled cooking time.

Sausage or calibre	Guideline time	Classification
Wiener/Frankfurter, 22/24 sheep casing	By rule of thumb about 22–24 minutes	Up to about 72 °C core temperature
Scalded sausage in 32/34 casing	A good 30 minutes	Proven example of the calibre rule
Krakauer, coarse scalded sausage, about 30–45 mm	About 30 minutes	Additionally check core temperature
Cervelat, Jagdwurst or Lyoner	20–90 minutes	Depending on the respective calibre

The clock only provides a planned value. Starting temperature, batch, and calibre can change the duration. The decisive factor remains a core temperature of about 72 °C with water within the proven range.

Which temperature table applies to scalded sausage?

A common temperature framework applies to scalded sausage, which is supplemented by proven special values according to type and calibre. The table uses 75–80 °C water and about 72 °C core temperature as a standard. Only Wiener or Frankfurter sausages in a 22/24 sheep casing get 75–78 °C, because a specific range exists for them.

Sausage type	Calibre	Water temperature	Core temperature	Guideline time
Wiener/Frankfurter	22/24 sheep casing	75–78 °C	About 72 °C	By rule of thumb about 22–24 minutes
Scalded sausage in general	32/34 casing	75–80 °C	About 72 °C	A good 30 minutes
Krakauer, coarse scalded sausage	About 30–45 mm	75–80 °C	About 72 °C	About 30 minutes
Cervelat	Depending on product	75–80 °C	About 72 °C	20–90 minutes depending on calibre
Jagdwurst	Depending on product	75–80 °C	About 72 °C	20–90 minutes depending on calibre
Lyoner	Depending on product	75–80 °C	About 72 °C	20–90 minutes depending on calibre

The guidelines replace neither recipe specifications nor the core measurement. For mixed batches, each relevant calibre group must be assessed separately.

Why is a core temperature of about 72 °C the target?

A core temperature of about 72 °C is the target because this value is set as the shelf-life standard for scalded sausage. About 68 °C merely marks the beginning of protein coagulation. The lower mark is therefore not sufficient as a completion criterion if the product is to be manufactured according to the proven standard.

Core value	Technical meaning	Consequence
About 68 °C	Beginning of protein coagulation	Do not end the process solely because of this
About 72 °C	Shelf-life standard	Use as target core temperature

Measure with a clean, suitable probe on a representative sausage. Different calibres need separate checks; the water temperature display does not replace the delayed reaction of the product core.

What mistakes happen during scalding?

The most common mistakes are caused by too much heat, poor reddening, incorrectly dosed or distributed nitrite curing salt, and a lack of quenching. Scalding water above 80 °C or smoking above 70 °C can cause casings to burst and fat to leak out. Every correction must isolate the cause and adjust the next process in a controlled manner.

Error pattern	Proven possible cause	Safe correction
Casing burst, fat leaked out	Scalding water above 80 °C or smoking above 70 °C	Limit temperatures and increase them slowly and steadily
Grey edge or grey core	Reddening too short or too cold; too little or old nitrite curing salt; salt unevenly distributed	Check reddening and salt distribution; only dose suitable nitrite curing salt correctly
Unclear degree of cooking	Only worked by time, core not checked	Measure about 72 °C core temperature in a process-suitable way
Forgot to quench	Process step not prepared	Provide clean ice water directly after scalding and quench sausages

For scalded sausage, the nitrite curing salt dosage is 18–22 g/kg. The sausage meat is kept below 12 °C with flake ice; salt and ice must be worked in evenly. Plastic or barrier casings are smoke-impermeable and only intended for scalded or cooked goods, whereas natural casings in the curing and smoking accessories as well as fibrous casings are water- and smoke-permeable.

What should be considered when scalding sausages commercially?

In the commercial sector, scalding sausages must be managed as a controlled process with suitable temperature measurement, documented target values, and hygienic probe handling. The relevant guidelines are 75–80 °C water and about 72 °C core temperature. Which records are required is determined by the respective HACCP plan together with the product, batch, and operational procedure.

The HACCP guide for smoking businesses categorises central control questions; in the boiling and scalding kettles category, suitable designs can be compared, while the electric boiling kettle 150–400 l with digital temperature control and core temperature probe supports the measurement process.

Series	Proven process equipment	Price
Electric square 150–400 l	Ready to plug in 400 V, digital temperature control, core temperature probe, no chimney connection required	from 8.954,75 € (as of 07/2026)
Gas square 150–400 l	Atmospheric burners for propane or natural gas, digital control, 130 mm exhaust nozzle	from 9.891,28 € (as of 07/2026)

No core temperature probe is included for the gas series; the core needs a separate, process-suitable measurement. Kettle control and core checking remain different tasks.

When is a pot enough for scalding sausages?

A pot is sufficient for single, manageable batches if the water and sausages have enough space and the temperature remains stably measurable. Even in a pot, 75–80 °C water and about 72 °C core temperature apply. A scalding kettle is a better fit as soon as regular quantities, reproducible processes, or operational documentation become unwieldy with a pot.

Solution	Proven features	Suitable if...
Large pot	Existing stove technology and separate measurement	a single batch remains controllable
Mini electric kettle 80–100 l	8 kW/400 V, thermostat; from 1.804,04 € (as of 07/2026)	a small home slaughtering or club festival is planned
Sheet steel kettle stove 100–250 l	Wood firing, fireclay, optional outlet; from 1.604,12 € (as of 07/2026)	classic home slaughtering with wood firing is suitable
Multi-fuel burner round 150–300 l	Wood firing, fireclay, V2A stainless steel (AISI 304), safety outlet, temperature display; from 4.812,36 € (as of 07/2026)	larger, regularly organised batches are coming up

A general quantity for switching to a kettle is not specified. Arguments against the pot include unstable temperature, dense packing, unsafe removal, or a lack of reproducibility. Wood and gas models have a 130 mm exhaust nozzle and require suitable installation.

What are frequently asked questions about scalding sausages?

Can sausages be removed at a core temperature of 68 °C?

Not according to the shelf-life standard applied here. About 68 °C merely marks the beginning of protein coagulation, while about 72 °C is considered the target core temperature. Continue the scalding process in a controlled manner without heating the water above 80 °C, and confirm the core value with a suitable measurement.

Can the scalding water boil briefly?

No. Scalding water should remain in the range of 75–80 °C and must never boil. If it exceeds 80 °C, casings can burst and fat can leak out. Reduce the energy supply, stabilise the temperature slowly and steadily, and continue to rely on the measured core temperature for product release.

Where is the core temperature measured?

Measure in the core of a representative sausage with a suitable, clean probe. With multiple calibres or significantly different batch areas, separate checks make sense. The specific measurement routine belongs in the operational process and hygiene plan; the water temperature display does not replace the product core.

Why are sausages quenched after scalding?

After scalding, the sausages should be quenched in ice water. Prepare sufficient clean ice water and hygienic containers for this so that the step can take place without delay. Quenching replaces neither reaching a core temperature of about 72 °C nor the subsequent hygienic handling and storage.

What nitrite curing salt dosage and sausage meat temperature apply?

For scalded sausage, 18–22 g of nitrite curing salt per kilogram is specified. The sausage meat should be kept below 12 °C using flake ice. Do not use old nitrite curing salt, distribute salt and ice evenly, and additionally adhere to the applicable recipe, labelling, and operational guidelines throughout the entire process.
