When you are in the market to buy honey, what do you look for? With that question, I want you to ignore things like the size/volume of the container, the variety, the source country (origin), color, and the state of the honey itself. My question focuses on the way that the honey has been harvested and handled - from the time that it was removed from the bee hive until the time that is placed into a bottle for the customer. You may not even care, but the potential differences between the honey that is offered to the shopper may be surprising!
There are many words that are used to describe how honey is processed ……. Or not. It’s not unusual to find words like unpasteurized, pasteurized, strained, unfiltered, raw, and natural on the label. But understanding what these words actually mean is more confusing than one may think. When honey producers select a phrase or word to put on the label of their honey, it is an attempt to better inform the potential customer about what processes (if any) the honey has went through before it was bottled. Although, however well-intentioned this may be, there can still be confusion about the honey unless consumers understand the true meaning of all this terminology. So, welcome to Part 1 – “Let’s Talk About Honey”.
In this article, I will be focused on several terms related to the filtering/straining procedures that are potentially used during honey extraction processes. Those terms include screening and filtering. There is a big difference between the two!
After the honey is harvested from the frames of a beehive box, there will be some foreign matter that remains in the honey. The majority of this foreign matter is either bits of wax or small chunks of propolis. Since the end goal is to bottle pure honey without this foreign matter, either screening or filtering is recruited in the process to do the job. That is so important that I want to repeat that point once again – “ Screening and Filtering are two different animals altogether!” Both procedures use different equipment arrangements and the ending honey product is different as well.
First let’s address what filtering is, why it is done, and how it affects the honey product in the end. The honey filtering process involves pushing honey by pressure through filters that have nearly microscopic openings. Commercial honey producers will commonly use filters that have a size 50 micron opening or close to that. This is a significant point that will be brought up later on. Filtering is included as part of the process (commonly used by large honey packing companies) so that a minimum amount of foreign matter remains in the honey as it is bottled. It is a preferred process by the large honey packing companies as it may hinder some honey crystallization short term. Honey that is filtered will likely have nearly all of its naturally occurring pollen removed!! More on that later.
Next, lets take a look at straining or screening. Straining is a term that is more easily understood and used by the consumer, not the beekeeper. Beekeepers use the term screening in place of straining. Both are used to describe the same process. Since I am a beekeeper, I will use the term “screening” from here on. The screening process involves passing the extracted honey through circular bowl-shaped screens in order to separate out the wax and propolis pieces/chunks. Beekeepers rely on gravity to move the honey slowly through screens. Screens are readily available in 200 micron, 400 micron, and 600 micron opening sizes. The higher the micron opening size, the larger the opening. Screens are very efficient at removing the large pieces of foreign matter. Generally, most foreign matter visible to the naked eye will be removed and the honey will be nearly crystal clear. I utilize a double screen setup to separate the foreign matter from the honey that my bees produce. My screen opening sizes are 400 microns and 600 microns. After screening, my honey is ready to bottle for the customer.
Now, it’s time to revisit the use of filters, typically 50 microns in opening size. Again, filters are typically used by larger commercial honey bottling companies. Today, many folks seek out honey because it can be used homeopathically as an anti-allergen. Almost all honey that has not been filtered will have pollen present in it. Most grains of pollen range in size from 50 microns to 100 microns. So, it is easy to recognize that filtering removes virtually all of the pollen from honey. However, on the other hand, honey that has been screened will retain the pollen that occurs in it. It is worthy to note that the naked eye cannot see particles (objects) smaller than 60 to 70 microns in size. So, most likely, you will not be able to see the pollen grains that are present in honey. If you are seeking honey that has pollen in it, look for honey that has not been filtered. The honey label should read “unfiltered”.
