HI Lisa, I am a big fan of your blog and of your Glycerites book. I learned about you through my Formula Botanica training. So far I am successfully selling a number of products I've formulated, but they are all anhydrous. I would LOVE to learn more about formulating preservative-free water-based products. What is the best way to do that? Do you have a book about it? Or articles? I'd love to learn how you've made the pineapple glycerite self-preserving. Wowza. Thank you so much.
Hey there Unknown — thanks for your kind words! If you look in the glycerites book, there are calculation charts for making preservative free glycerites with all kinds of raw materials - also fresh foods :) As for leaning more about Hurdle Technology, there are a few more articles about it on this blog with links to more information that could be a starting point. :)
