Innovative natural vitamin testing in fresh produce

 

In collaboration with Kyomei Ltd through Innovate UK, we have developed advanced methods to measure vitamin levels in fresh products. Using LC-MS techniques, we can accurately measure natural vitamin levels in fruits and vegetables, providing companies with a comprehensive understanding of the nutritional profile of these products. We can test for:

 

  • Water-soluble vitamins, including the full range of B vitamins and folates
  • Fat-soluble vitamins like E (alpha- and gamma-tocopherol), D (both D2 and D3), and K1, plus beneficial compounds such as beta-carotene and lutein

 

Vitamins & minerals testing methods

 

At RSSL, we combine cutting-edge technology with high quality and scientifically proven methods to provide accurate and reliable results. All testing takes place in our ISO-accredited laboratories, we provide the following techniques. 

 

UPLC Image

Ultra-Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS/MS)

 

UPLC-MS helps us to measure vitamins at very low concentrations. When we're dealing with complex samples, like fortified foods and supplements, our UPLC-MS/MS techniques can pinpoint and measure specific vitamin types with outstanding accuracy. Our specialised methods are particularly valuable when analysing B vitamins in solid materials - which are complex to analyse.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)/ Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES)

 

When testing for minerals in food, ICP-MS or ICP-OES allows us to quickly and accurately detect and measure multiple minerals across various samples.
