Water blanching is performed in hot water at temperatures
ranging typically from 70C to 100C. However, lowtemperature
long-time (LTLT) blanching and combinations
of LTLT with high-temperature short-time (HTST)
blanching have also been studied.[3–5] Water blanching
usually results in a more uniform treatment, allowing
processing at lower temperatures. There are water
blanchers that use a screw or a chain conveyor to transport
the product inside the tank, where hot water is added.
