Overview: why it matters to choose the right vitamin analysis method?

In the food, dairy, functional food, and animal feed industries, vitamin analysis plays an extremely important role in:

- Ensuring the declared content is correct

- Controlling product quality

- Meeting export standards

However, many businesses struggle to choose the right method among 👉 HPLC – microbiological test – test kit

So which is the optimal method? This article will help you understand clearly.

1. HPLC (high-performance liquid chromatography)

- HPLC (High Performance Liquid Chromatography) is a modern analytical method for separating and quantifying compounds, including

* Advantages

- Very high accuracy

- Detailed quantitative analysis of each vitamin type

- Widely recognized in testing

* Disadvantages

- High equipment investment cost

- Requires specialized technicians

- Relatively long analysis time

- Complex sample preparation process

When should HPLC be used?

- Official testing

- Product declaration

- Export (EU, USA)

- Advanced analysis

2. Microbiological method (microbiological test)

- This method uses microorganisms to determine vitamin content (especially B-group vitamins).

* Advantages

- Suitable for some vitamins such as B12 and B1

- Cheaper than HPLC

* Disadvantages

- Long analysis time (24–72 hours)

- Accuracy depends heavily on handling

- Hard to control errors

When should it be used?

- Traditional laboratories

- B-group vitamin analysis

- When HPLC is not available

3. Vitamin rapid test (test kit)

- This method uses rapid test kits to determine vitamin content in a short time.

- R-Biopharm products are among the popular solutions today.

* Outstanding advantages

- Fast (a few hours)

- Easy to use

- No complex equipment needed

- Suited to internal QC

- Cheaper than HPLC

* Disadvantages

- Does not completely replace HPLC for official declarations

- Some analytes have limits

When should a test kit be used?

- Rapid testing of incoming raw materials

- Testing during production

- Screening before sending samples to HPLC

- Routine checks

When should you choose a test kit over HPLC?

This is a question many businesses care about. You should choose a vitamin test kit when:

✔️ You need fast results

You cannot wait 1–3 days like HPLC

✔️ You want internal control (QC)

- Test immediately at the factory

- Detect deviations early

✔️ You want to optimize costs

- No large machinery investment needed

- Lower sample shipping costs

✔️ You test large volumes

Checking many samples each day

The optimal combined solution

- In practice, businesses should apply: test kit + HPLC

Specifically:

- Test kit → rapid testing, screening

- HPLC → official confirmation

👉 This is a way to:

- Increase QC efficiency

- Reduce costs

- Optimize time

Mistakes when choosing a vitamin analysis method

- Using only HPLC → costly, slow

- Using only test kits → missing official confirmation

- Not testing periodically

- 👉 The right solution is flexible combination

Conclusion

Today there are 3 main methods for vitamin analysis:

- HPLC → high accuracy, for declarations

- Microbiological test → traditional, slow

- Test kit → fast, economical, suited to QC

👉 Among them, R-Biopharm's vitamin test kits are becoming the trend thanks to their convenience and effectiveness.
