However, a reality many businesses face is:
- The actual vitamin content does not match the declaration on the packaging
- This affects not only brand reputation but can also lead to:
- Product recalls
- Failing export standards
- Loss of customer trust
- So is vitamin testing in food really necessary? And what is the optimal solution today?
⚠️ Why must businesses test vitamins?
1. Vitamins are easily lost during production
- Vitamins, especially water-soluble ones like Vitamin C and the B group, are easily degraded by: high temperature, light, oxy
👉 This means the vitamin content in the final product can drop significantly compared with the original raw material
2. Declaration deviations – a huge legal risk
- By regulation, the business must ensure: the vitamin content matches the label declaration
- Otherwise:
- Fines are possible
- The shipment may be re-tested
- Exports can be rejected (especially in the EU and US markets)
3. Product quality control (QC)
In the QC system, vitamin analysis in food helps:
- Control incoming raw materials
- Ensure production quality
- Check finished products before leaving the factory
4. Optimizing production costs
- It sounds counterintuitive, but not testing vitamins = easy over-fortification.
- This leads to: higher ingredient costs and lower profit.
🧪 Current vitamin testing methods
There are 3 common methods today:
1. HPLC (liquid chromatography)
* Advantages
- High accuracy
- Detailed quantitative analysis
* Disadvantages
- High investment cost
- Needs specialized technicians
- Long analysis time
2. Microbiological assay
* Advantages
Applicable to some B-group vitamins
* Disadvantages
- Long duration (24–72 hours)
- Prone to error if handling is not standard
3. Vitamin rapid test (test kit)
This is the trend increasingly chosen by businesses.
* Outstanding advantages
- Fast (a few hours)
- Easy to use
- No complex equipment needed
- Cheaper than HPLC
👉 Especially suitable for:
- Internal QC
- Rapid testing before sending to a lab

- Rapid testing of incoming raw materials
- Testing during production
- Checking before sending samples to HPLC
- Verifying anomalous results
Common mistakes when testing vitamins
To ensure accurate results, avoid:
- Not homogenizing the sample
- Storing the sample incorrectly
- Not calibrating the equipment
- Handling that does not follow the procedure
👉 This is why standardized test kit solutions like R-Biopharm's should be chosen
