Currently there are two main methods being used to pasteurize the almonds. One
uses steam to sanitize the nuts, while the other uses the chemical propylene oxide,
aka PPO, which is considered a possible carcinogen. Most conventional almond

be discarded as a method. Consumer awareness is constantly rising – public
criticism of the PPO process is just a matter of time.
Today there are several manufacturers of nut pasteurization systems using steam.
One of them is Log5, a spinoff of the post-harvest technology group Royal Duyvis
Wiener. 2017 Log5 received the Industry Excellence Award in the category
‘Processing Innovation’ at Gulfood Manufacturing. The Clipper talked to Tom
Velthuis, International Sales Manager at ANUGA FoodTec about their innovative
