- Vacuum pasteurization — Correct Answer
- Uperization
- Stassanization
- HTST pasteurization
Explanation:
Correct Answer: Vacuum pasteurization
Vacuum pasteurization (Vacreation) is the process of pasteurizing milk under reduced pressure using direct steam, carried out by a Vacreator instrument.
Pasteurization Methods — Quick Reference
| Method | Temperature-Time |
|---|---|
| LTLT (Batch/Holding) | 63°C / 30 minutes |
| HTST (Flash) | 72°C / 15 seconds |
| Stassanization | 74°C / 7 seconds |
| UHT | 130–135°C / fraction of a second |
| Uperization | 150°C / fraction of a second |
| Vacuum (Vacreation) | Direct steam under reduced pressure |
Special Use of Vacreation
Vacreator is used to remove feed and other volatile flavours from cream and to pasteurize it for butter making.
