Jacobs <\/a>Kr\u00f6nung<\/a> Freeze Dried Instant Coffee <\/a><\/figcaption><\/figure>\n<\/div>\n\n\n

Just putting this out there: I have noticed that I have a predictable and severe allergic<\/strong> reaction on drinking Jacobs coffee. The coffee is just fine, but the headache is two hours later. I believe the reason is that the coffee contains traces of egg white<\/strong>. <\/p>\n\n\n\n

Someone back when (Pasteur?) thought it was a good idea to stimulate the immune system by giving intravenous jabs of all manner of disease. The theory<\/strong> is that your body recognises the disease and has an allergic reaction to it. For years. That’s vaccines. How do they get enough diseased muck to give everyone a bit? They grow the diseased muck on egg albumen. Inject the diseased muck into babies, and then next time diseased muck comes about, they will give a full allergic reaction to it: headache, temperature and vomiting. That’s the theory. How useful it is to have this form of reaction to a disease is debateable. The practice<\/strong> is that my body recognises the egg white that they didn’t clean out of the muck they injected, and has an allergic reaction to that instead. For years. So now I am a walking egg-white detector. The tiniest bit of it will do: I can detect it, and get a headache, and throw up. It’s the most pointless super-power in the world, and I’ve got it.<\/p>\n\n\n\n

I suspect that the reason for my allergic reaction to Jacobs coffee is that Jacobs coffee is freeze-dried in a system that is also used for manufacturing freeze-dried eggs: I suspect that a machine that was used for drying egg whites is also used for manufacturing the coffee. Perhaps the testing of the machine at the factory leaves traces of egg, or perhaps the machine is used for multiple purposes on a regular basis, without adequate cleaning to remove allergens. <\/p>\n\n\n

As an example of this dual-purpose system, you can buy the Industrial Egg White Spray Dryer Production Line Instant Coffee Powder Spray Dryer Machine Spray Dryer Egg Whites<\/a> machine for under 3k USD, and it will do freeze drying for both instant coffee and freeze-dried eggs. Having spent all of that money, it would be a shame to have to use it for only one purpose.<\/p>\n\n\n\n
