FAQ
Why use freeze-dried onion in energy bars?
Freeze-dried onion enables savory bars with punchy aroma and a light, crisp texture while adding minimal moisture.
It’s common in savory meal bars, protein bars, and “everything” style snack bars, but requires humidity control to prevent softening.
What format of freeze-dried onion is best for bars?
Most bar manufacturers choose minced/small dice for even distribution and fewer cutting defects, and use powder for binder flavoring.
Flakes can look premium but often create fines and uneven bites in dense bars.
When should freeze-dried onion be added in bar production?
Add it late in mixing at low speed to reduce breakage. If your binder is warm, keep temperature controlled and minimize dwell time before forming.
How do I prevent freeze-dried onion from turning soft in bars?
Control binder moisture/temperature, reduce humidity exposure during staging, and use high-barrier packaging.
Moisture migration from syrups or nut butters is the most common cause of softening.
What specs should I request on a COA for freeze-dried onion?
Request moisture and water activity, cut size distribution and fines %, sensory notes, microbiological results, ingredient statement, country of origin,
and certifications (organic, kosher, non-GMO) as needed. For bars, fines control and moisture/aw are especially important.
Is freeze-dried onion the same as dehydrated onion?
Not exactly. Freeze-dried onion is typically lighter with faster aroma release and a crisp texture. Dehydrated onion is denser and may have a more cooked profile.
The best choice depends on your target sensory and processing conditions.
