Here is my memo for today, on Flavor care. (Updating an old Article!)

Knowing what to do for flavor care is simple. Every concentrated flavor is a mixture of raw materials, and every flavor blend can act differently. For example flavors that have a vanilla characteristic are going to have slightly different storage capabilities than fruit flavors. Here’s the reason : vanilla and caramel flavors are mostly made of large molecules like vanillin, ethyl vanillin , etc.; we call them compounds in a finished flavoring. 

You need to keep the following info as a reminder

Whenever you open a bottle, it’s the lightest and smallest molecules that escape and reach your nose quickly. Over time when you open a bottle over and over again more and more proportion of these lighter molecules leave the bottle and eventually the character of the flavor will be changed. This doesn’t mean the flavors spoiled, it’s just different. So this is one piece of advice, if you are going to store a flavor for a long period of time, transfer the flavor to smaller bottles that will you will not have to open over and over again.

Actions for flavorings, causes

When a flavor is warm, like if it’s a hot day, when you open the bottle even more of the volatile molecules will escape, much more will escape than if the flavor was cool. This is true for all liquids, when liquids are heated the molecules are much more easily converted to their gaseous state. This is also the reason why you should not be “top off” on creating your juices, as they depend on the gases to help steep into your base mix.

Help and storage

HDPE plastic, is very resistant to interaction with the flavors.
However, even with HDPE plastic, I really wouldn’t recommend storing them for longer than a month or so.. It’s much better to store things long-term in glass, or PET bottles, and it is not a good idea at all to store the flavors with the plastic eyedropper caps on the bottles. The rubber that’s used with the eyedropper’s is extremely soft and interacts with the flavoring. Some Flavors can appear to eat into, and other flavors will demolish rubber dropper tops, depending on the compounds inside them.

Shelf Life

Shelf life is very important to keep in mind. For Flavorah, the shelf life is between 6 months and 3 years, depending on how your flavors are stored. You will need to keep an eye on them for possible spoilage. Not to scare anyone, but common reactions with lights, heat and coolness causes flavors to react, or age. The other interesting bit is the cinnamon types, and you will want to keep an eye out on them. If your bottles are starting to “suck in” or become distressed, toss them out.

The rest you will want to hold up to a light and check for any types of “floaters” or crystals. If so, you want to shake the flavors back together. It is a sign they have been sitting too long and have not been in use. Always shake them too when mixing. It is important to take care of your flavors so they will last you more than their deemed shelf life.
