Research Project: Development of Sensors for Instantaneous Assessment of Peanut Pod Moisture

Location: Peanut Research

2013 Annual Report


1a.Objectives (from AD-416):
Develop and test, in different environmental conditions, sensors to rapidly and nondestructively determine the moisture content in peanuts.


1b.Approach (from AD-416):
Sensors, suitable for use in laboratory conditions, will be developed and tested at NPRL. Sensors suitable for field and industry use, will be developed in Australia and tested at two different locations.


3.Progress Report:

This research relates to in-house objective 1: Determine spectral response characteristics (near infrared, visible, ultraviolet, and radio spectra)of in-shell and shelled peanuts related to various quality parameters such as oil chemistry, maturity, moisture content, protein, flavor and seed viability.

Measurements, along with collaborators, were made on several samples/varieties of peanuts grown in Australia, at their laboratories in Kinagaroy, Queensland, Australia, during site visit in May 2012, on the prototype meter developed. Calibrations for both moisture and oil determination in peanuts were done on the instrument for varieties such as Tingura, Fisher, and Fansfield. All the results were analyzed using statistical packages. The moisture content predictions were as good as for American varieties. The results are being consolidated and will be published shortly. Similarly the oil measurements were analyzed and the results were encouraging. A manuscript was prepared, and was accepted for publication by a peer-reviewed journal. Further collaborative efforts are under progress to develop a commercial model exclusively for peanut oil determination nondestructively and rapidly.
