Hi Patricia,

I’m familiar with the HPP process but thank you for posting that information for others. I think that HPP is probably the most common method currently in use as a kill step, if a company is using a kill step.

I personally have had communication with three separate companies of freeze-dried products who reported that they heat the product after the freeze drying process. One company reported that they heated the product to 170 degrees and held it at that temperature for 1 hour.

I will not name the companies because their processes may or may not have changed since I talked to them, but at the time of conversation they reported that is what they did.

Microwaving was discussed in an industry forum, and it was disclosed who apparently was using this method as a kill step after the freeze-drying process. I’d consider the individual reporting on it fairly well known in the industry. They stated that they verified the claim.

I do agree kibble is a convenience food, just as are any of the commercially prepared diets, be they freeze dried, commercial raw, or canned.
