Vegetable oil is an essential ingredient in food processing, but it also poses potential safety risks if quality is not strictly controlled.
Vegetable oil testing helps businesses accurately evaluate physicochemical, safety, and microbiological parameters, thereby meeting legal requirements and protecting consumer health.
The article below will help you clearly understand the nature, procedure, and benefits of vegetable oil testing before bringing products to market.
What is Vegetable Oil Testing?
Vegetable oil testing is the process of analyzing oil samples in a laboratory to determine physicochemical, microbiological, and safety parameters in accordance with Vietnamese legal regulations. The testing results help evaluate whether the oil meets market standards and is safe for consumer health.
This activity is typically performed by accredited testing units, such as VNTEST, for the following purposes:
- Product declaration
- Internal quality control
- Import and export
- Inspection and post-market surveillance
Legal Basis for Vegetable Oil Testing
No. | Legal Document | Applied Content |
|---|---|---|
1 | Law on Food Safety No. 55/2010/QH12 | Regulates the responsibility to control and ensure food safety, including vegetable oil |
2 | Decree 15/2018/ND-CP | Specifies details for implementing the Law on Food Safety; requires testing for product declaration |
3 | QCVN 8-2:2011/BYT | Maximum limits for heavy metal contamination in food |
4 | QCVN 8-1:2011/BYT | Limits for mycotoxin contamination and harmful substances |
5 | TCVN 7597:2018 | Standards defining physicochemical parameters for edible fats and oils |
6 | Circular 19/2012/TT-BYT | Guidelines for quality management and food safety regarding food additives and ingredients |
Why Does Vegetable Oil Need to Be Tested?
Sourced from seeds, fruits, or plant germs, vegetable oil is highly susceptible to oxidation, contamination with impurities, or quality degradation during production and storage. Testing is necessary to:
- Detect substandard, recycled, or adulterated oil
- Control heavy metal residues and toxic impurities
- Ensure products comply with food safety technical standards
- Protect brand reputation and consumer health

Commonly Tested Parameters in Vegetable Oil
No. | Group of Parameters | Parameter Name | Evaluation Purpose |
|---|---|---|---|
1 | Physicochemical | Acid Value (AV) | Evaluates hydrolysis degree and oil quality |
2 | Physicochemical | Peroxide Value (PV) | Determines oxidation level and whether the oil is rancid |
3 | Physicochemical | Free fatty acid content | Controls stability and shelf life of the oil |
4 | Physicochemical | Moisture and insoluble impurities | Evaluates oil purity |
5 | Physicochemical | Saponification value | Determines oil characteristics and origin |
6 | Safety | Heavy metals (Pb, As, Cd, Hg) | Ensures the oil is non-toxic to human health |
7 | Safety | Extraction solvent residue | Controls safety during the extraction process |
8 | Safety | 3-MCPD and Glycidyl esters (if applicable) | Detects substances with cancer risk |
9 | Microbiology | Total aerobic microorganisms | Evaluates hygiene conditions and storage status |
10 | Microbiology | Yeasts and molds | Prevents microbial contamination causing spoilage |
Standard Vegetable Oil Testing Procedure Today
The testing process usually consists of the following steps:
