    The amount is not really terrifically important. Even minuscule amounts can trigger a reaction in sensitive individuals.

    Thank you for all the comments. Last season we used unsalted butter. We are just hobby producers selling to friends, family and to individuals on our website etc but after last season I started thinking about those things with the possible dairy alergies etc so now I'm trying to figure out what to use for this season.

    Dr Perkins what are you using for a defoamer since you don't think dairy products are a good choice? What do you recommend to use?

    We use organic canola oil.....it seems to work better in the liquid form than the spray does. We purchase it from our local natural foods store.

    By me bringing it up was not meant to slam those that use it (including me. But I approach it and use it as a "necessary evil". I do not buy all of these allergic reactions that people seem to have. There is something else involved causing some of these so called allergic reactions other than what we are told in my opinion. Lawyers are one of them!

    Why did we not hear of these mass allergies 30 years ago? Some of it is 80% of the food in a supermarket would not have been on the shelf 80 years ago. I belive all of the processing of food making it junk has alot to do with this matter.

    I have always heard and read that canola (rapeseed) is bad, bad, bad for the body. I have read about people using organic sunflower and safflower oil for organic.

    Cream does have about half the protein content compared to milk. The milk allergen sensitivity threshold starts at about 600 ppb, so your margin of safety is not all that tremendously huge. Your calculations are for the entire season and are valid for your entire crop.....but what about the end of the season syrup when you're using much more defoamer than at the beginning? Do you use twice the normal amount, 3X, 4X, 5X.....at that point you are creeping into the zone of sensitivity for some people.

    Let's say instead that you use cream (or milk, or butter) in making maple cream, or candy. At that point, there is almost no dilution factor and you're going to be well over the threshold of some highly sensitive individuals.

    It is safer for most people to simply use approved products. You're fine (apparently) assuming the risks, but it clearly is not the best approach for most producers.

    A relatively small percentage of the population have true allergies. A good deal more claim to, or believe they are allergic to certain things. Perhaps they got sick once after eating something, and now think they are allergic. Same goes with people with service dogs, or those who park in handicap spaces because their legs hurt (but probably best not to start that conversation). In any case, TRUE allergies are life-threatening and not something that is merely there to annoy the rest of us. Why are there more reports.....better communication. You hear about stuff that happens on the other side of the world 2 hrs ago these days. Secondarily, medicine manages to keep people with various medical issues alive. Centuries ago if you had diabetes....you died. You had bad eyes, you fell off a cliff (or couldn't hunt effectively). Nowadays, medicine, glasses, less hazardous lives....people live, reproduce, and pass on those genes.

    I am by no means an expert on defoamers. I do know that there are two ways to extract oil from a plant. One is by expeller extraction(squeezing oil out of plant). The other is by chemical extraction which produces hexane. The canola oil we use is expeller extacted, which does not involve use of chemicals. We started using this type of defoamer because it was recommended by organic certifier.
