Fermented Food Study and Taste Testing Video
By popular demand another video. Enclosed are part 1 and 2 video of fermented food taste testing followed by taste/odor study documents. Click on to start video and see documents. The documents will be a full amine, pH, TBA discussion on all the fermented foods brought in for tasting.
The study is a one point in time discussion and has no statistical significance. All markers reported have to do with industries attempt to describe the ferment and taste/odor experience. None of these markers are food safety discussion points. All these foods are not only food safe but are very likely as nutrient dense as any you will find on earth.
From my observation the flavor profile variations of our oils have been less pronounced the past two to three years compared to 3-6 years ago. I think the ferment starter we have developed overtime has assisted in the reduction of the products flavor profile. I guess similar to perfecting a cheese culture.
We did not include the wine/vinegar/balsamic vinegar in the video as we only had so much time. The report is included. Interesting, the oxidation marker for the balsamic vinegar is very high as a % of fat, 122-165 TBA. Dr. Jie shared with me that in China the very dark and thick vinegars are regularly consumed for health.
The rancid/toxic markers that are routinely checked for in the industry, as related to human health, are aldehydes and their conjugated hydroperoxydiene precursors. Our oils have been checked once and there are none, as expected. These products are a result of high heating of oils and our oils are not heated so these compounds are not a concern.
