Superfoods Quality Control & Assurance 3

Question 1

A superfood company discovers its chlorella tablets have elevated lead levels from a single harvest. Which corrective action best demonstrates a robust QC system?

Accepted Answer

Quarantine the batch, trace the contamination source, and retest before release

Answer

Quarantine and root-cause analysis followed by retesting is the proper CAPA (Corrective and Preventive Action) response in food quality systems.

Question 2

What is the primary purpose of an incoming raw material inspection (IQC) in a superfood manufacturing facility?

Accepted Answer

To verify supplier materials meet specifications before production begins

Answer

Incoming Quality Control (IQC) prevents non-conforming raw materials from entering the production line, stopping contamination and quality issues at the earliest point.

Question 3

Freeze-dried acai powder is found to have poor solubility in water compared to specifications. Which quality parameter most likely failed?

Accepted Answer

Particle size distribution

Answer

Particle size directly controls solubility and dispersibility of powders; oversized or clumped particles dissolve poorly and indicate a milling or drying process deviation.

Question 4

Under FDA regulations, superfood dietary supplements must be manufactured under which mandatory set of standards?

Accepted Answer

Current Good Manufacturing Practices (cGMPs) — 21 CFR Part 111

Answer

21 CFR Part 111 establishes cGMP requirements specifically for dietary supplements, covering facility, personnel, equipment, and production controls.

Question 5

A lot of maca root powder fails a yeast and mold count test (result: 10,000 CFU/g; limit: 1,000 CFU/g). What is the next appropriate step?

Accepted Answer
