Aprofood offers comprehensive analytical solutions for the determination of fat-soluble and water-soluble vitamins in samples through advanced analytical techniques and the latest international standard methods, supporting individual analytical needs of clients.
Vitamins in Food Products
Vitamins are a collective term for a range of organic compounds. There are dozens of known vitamins, which are categorized into two main groups: fat-soluble and water-soluble. By accurately measuring the vitamin content of a food, beverage, or dietary supplement, a product's competitive advantage can be enhanced. EU regulations require that the concentration of vitamins in a food or supplement be labeled on the package only if the vitamin is present in a significant amount, and vitamin content analysis is a key method of verifying labeling compliance, especially if the food or supplement claims vitamin-related health benefits.
Our Service
Aprofood laboratory network offers vitamin detection across a wide range of food matrices. We employ different analytical methods tailored to the sample types provided by clients, including SFE-SFC, UPLC, HPLC, GC, LC-MS, microbiological assays, or fluorescence-based quantitative analysis, enabling efficient and precise measurement of vitamin content variations.
For common vitamins and their metabolites, detection can be performed using reference standards. For rare vitamin molecules, customized testing is available upon provision of standard samples. Additionally, Aprofood provides vitamin assay kits to meet diverse client needs.

Frequently Asked Questions (FAQs)
Q1: Can special samples (e.g., juice, oil or powder) be tested?
A1: Yes, we can test them. We employ appropriate pretreatment methods (e.g., saponification, solid-phase extraction) for oil/juice samples, while powder samples can be analyzed directly.
Q2: What is the minimum sample size required for testing?
A2: For routine analysis, 3–5 g of solid samples or 5–10 mL of liquid samples are required. For trace-level vitamin detection, 10–20 g of sample is needed.
Q3: What are the precautions for sending samples?
A3: Samples should be shipped at room temperature or under refrigeration, protected from light (especially for fat-soluble vitamins). Use airtight, light-resistant packaging and include a sample information form.
Q4: How is the testing fee calculated?
A4: The cost is determined based on the specific testing items, sample matrix, and whether stability analysis is required.
