Measuring and Sorting Seeds
Determining Content of Fatty Acids for Seed Classification
Oleic acid is a fatty acid that occurs naturally in several oils, and peanuts are a particularly good source of high‑oleic content with advantages over other edible oils. Typically, laboratories test peanuts’ acid content by gas chromatography (GC), a method that is costly, labor, and time intensive. Breeding programs, however, must rapidly analyze and sort vast numbers of peanuts at every stage, especially at harvest time, which makes GC a significant constraint.
Brimrose AOTF‑NIR spectrometers provide a fast, non‑destructive alternative NIR solution for rapidly analyzing large sample volumes with minimal labor required, supporting efficient decision‑making in breeding processes. With true single‑seed analysis, our spectrometers give breeders the ability to selectively discriminate, qualify, and sort seeds for the most desired qualities. Thousands of samples can be tested quickly with minimal cost or time consumption.
REQUEST INFORMATION
Sorting Peanut with Brimrose Luminar 3076 SeedMeister Mark IIIx
A BETTER METHOD
AOTF-NIR spectroscopy is a non-destructive test method for rapidly sorting peanuts. The method involves the following steps:
Models are built using established GC data.
The SEEDMEISTER Mark IIIx is configured in a minimal amount of time to scan the seeds.
Models are imported to the SEEDMEISTER’s software for predicting the peanuts’ concentration ratio of oleic and linoleic acids.
Peanuts are sorted to one of the gates based upon predicted results. The SEEDMEISTER Mark IIIx is an accurate, repeatable, and low-cost solution for sorting peanuts. Other types of seeds can also be measured and sorted with other Brimrose Spectrometers. Models have been developed for coffee beans, soybeans, watermelon, corn, and many more.

Brimrose Luminar 3076 SeedMeister
A PROVEN BENEFIT
Successful implementation of the SEEDMEISTER Mark IIIx has many proven benefits:
The breeding cycle may be shortened.
Minimizing GC use reduces chemicals and solvents that have serious health and environmental hazards.
The SEEDMEISTER Mark IIIx may tests up to 100 seeds in only 4 minutes, which would require more than 24 hours using GC.
Hundreds, even thousands, of peanuts may be tested at a site with zero testing costs and without destroying the product. Producers and manufacturers will have very high confidence that the peanuts will meet their customers’ specifications.
