Canola Oil Seed lack of oil
Seeds were stored in a silo 180' tall. All deliveries were checked for moisture before being put in the silo. The seeds were crushed for canola oil production but they did not produce oil. The seeds have gotten darker and will not produce oil now. They were loaded into the silo from January 2019 thru March. The silo was emptied after the discovery but no water entry was found and no wet spot in the seed either.
Any idea why the seeds appear to have heated or changed in the silo?
