Oil and Moisture in Seeds and Nuts

From Quality Control to Seed Breeding Programs

Since the financial value of the farmed seeds is critically dependent on the oil content, a rapid and reliable method for quantification is required. Such a method is provided with the minispec TD-NMR solutions, combining speed of analysis with outmost accuracy on the fundament of various recognized International Standard methods.

 

the minispec TD-NMR product line-up provides the most comprehensive solution packages:

the minispec mq-one Seed Analyzer (the QC solution)

the minispec mq-one Seed XL Analyzer (the QC solution for big/sunflower seeds)

the minispec mq7.5 Large Seed Analyzer (the R&D version for big/sunflower seeds)

the minispec mq10 Seed Analyzer (the R&D version for seeds)

the minispec mq20 or mq40 or mq60 (the Seed Breeding solutions: Analysis of small amounts down to single seeds)

 

The Method: As easy as winking

The minispec quantification of the oil content in seeds, like sunflower kernels, soy-beans, rape or canola seeds benefits from an ease-of-control and an ease-of-preparation:

 

  • preparation-free, grinding-free sampling
  • direct transfer of the seeds to the sample tube
  • weighing of the sample, mass is automatically transferred to minispec software
  • placing in the minispec, automatic start of the measurement
  • prompt result display within seconds
  • next sample, please!

Additional quantification of the moisture content comes for free. Within the same measurement process, the moisture content is determined simultaneously!
