Fat content (% by weight) |
Drives creaminess, flavor carry, and “soft bite.” Too high can increase oiling-out if the matrix is weak or warm-filled. |
Common: 35–70% fat depending on carrier. Higher-fat powders are often more sensitive to heat and shear. |
Carrier type maltodextrin / gum acacia / starch blends |
Carrier controls flowability, dispersion, and fat encapsulation. It can also affect sweetness perception and label preferences. |
Maltodextrin = economical, good flow.
Gum acacia = strong encapsulation, “cleaner” mouthfeel in some systems.
Specify carrier % if important.
|
Moisture (% max) |
Moisture influences clumping, microbial risk, and bar texture drift (hardening/softening over time). |
Common: ≤ 3–5% depending on grade. Lower moisture helps storage stability. |
| Water activity (aw) |
Low aw supports shelf stability. In bars, aw migration drives chewiness changes and can destabilize inclusions. |
Often < 0.35–0.45 for powders, but confirm by supplier COA/typicals. |
Particle size mesh / micron |
Affects dispersion, grittiness, and how the powder binds with syrups/oils. Finer powders generally blend more smoothly. |
Specify “fine” for smooth bite; “standard” for general use. If you have a sieve spec, list it. |
Flowability bulk density / angle of repose |
Impacts hopper feeding, dosing accuracy, and dusting. Poor flow = inconsistent bar weights and mixing variability. |
Ask for bulk density range and whether product is agglomerated for better flow. |
Flavor profile natural / toasted / neutral |
Flavor intensity can shift with origin and drying process. Consistency is critical for branded bars. |
Request a retained sample reference and lot-to-lot control notes if you scale. |
| Micro & food safety |
Energy bars are often no-bake. Your powder must meet micro targets suitable for ready-to-eat applications. |
Ask for standard plate count, yeast/mold, pathogens (per your program), and facility certifications. |
| Allergen statement |
Critical for label and cross-contact risk. Coconut is treated as a tree nut allergen in some markets and labeling programs. |
Request official allergen statement, cross-contact controls, and whether the facility handles dairy/soy/nuts/sesame. |
| Certifications |
Supports customer requirements and claims (organic, kosher, non-GMO, etc.). |
Common requests: USDA Organic, kosher, non-GMO statement, vegan suitability. |
| Shelf-life & storage |
High-fat powders can oxidize if stored warm or exposed to air. Shelf-life impacts your inventory strategy. |
Ask for shelf-life, recommended storage temperature, and whether nitrogen flushing is used. |
