Yogurt Production
General Manufacturing Procedure
The following flow chart and discussion provide a general outline of the steps required for making yogurt.
Processing Steps in Yogurt Production:
1. Adjust Milk Composition & Blend Ingredients
Milk composition may be adjusted to achieve the desired fat and solids content. Often dry milk is added to increase the amount of whey protein to provide a desirable texture. Ingredients such as stabilizers are added at this time.
2. Pasteurize Milk
Yogurt is pasteurized before the starter cultures are added to ensure that the cultures remain active in the yogurt after fermentation to act as probiotics; if the yogurt is pasteurized after fermentation the cultures will be inactivated.
3. Homogenize
The blend is homogenized (2000 to 2500 psi) to mix all ingredients thoroughly and improve yogurt consistency.
4. Cool Milk
The milk is cooled to 108°F (42°C) to bring the yogurt to the ideal growth temperature for the starter culture.
5. Inoculate with Starter Cultures
The starter cultures are mixed into the cooled milk.
6. Hold
The milk is held at 108°F (42°C) until a pH 4.5 is reached. This allows the fermentation to progress to form a soft gel and the characteristic flavor of yogurt. This process can take several hours.
7. Cool
The yogurt is cooled to low temperature to stop the fermentation process.
8. Add Fruit & Flavors
For swiss style yogurt the fruit is blended with the fermented, cooled yogurt prior to packaging.
9. Package
The yogurt is pumped from the fermentation vat and packaged as desired.
