TL;DR: The levels of mycotoxins gradually decreased with the increase in the time of exposure to UV-C radiation, demonstratingUV-C irradiation to be an effective method in fungal control and reduction of mycottoxins in stored rice.

TL;DR: In this paper, the authors evaluated the influence of germ storage (0, 30, and 60 days) from different corn genotypes (yellow floury, white floury and yellow flint corn) on technological properties and fatty acid, tocopherol, and carotenoid profiles of oil.
Abstract: The objective was to evaluate the influence of germ storage (0, 30, and 60 days) from different corn genotypes (yellow floury, white floury, and yellow flint corn) on technological properties and fatty acid, tocopherol, and carotenoid profiles of oil There was an increase in γ-tocopherol, lutein, zeaxanthin, and cryptoxanthin in yellow flint corn oil according to the increase of storage time There was a reduction in linoleic acid in yellow floury and flint corn oils as the storage time increased There was a reduction in γ-tocopherol and lutein in yellow and white floury corn as the storage time increased The α-tocopherol decreased during storage in all genotypes Yellow flint corn is indicated for extraction of oil due to the great conservation of germ during storage and higher content of carotenoids White floury corn, despite having a higher content of tocopherols in oil, showed higher degradation during storage which increases the production costs of oil

TL;DR: In this paper, the authors evaluated the effects of wind exhaustion system (with and without natural lighting) during soybean storage (0, 3, and 6 months) on energy cost, mass temperature, mass loss, and soybean quality.

TL;DR: In this article, the physicochemical and technological properties of flour, oil and protein isolate from defective soybean seeds were evaluated and the seeds were classified as not defective, partially fermented, completely fermented, and burned soybeans.
Abstract: The objective of this study was to evaluate the physicochemical and technological properties of flour, oil and protein isolate from defective soybean seeds. The seeds were classified as not defective, partially fermented, completely fermented, and burned soybeans. The intensification of defects promoted increases of 10.85, 2248.89 and 2031.98%, respectively, for ash, acidity, and oil lipase activity, and reductions of 11.25, 98.51 and 59.10%, respectively, for lipid content, protein extraction yield and protein solubility of the protein isolate, when compared to not defective soybeans. Increases in daidzein, genistein, and glycitein isoforms content were observed in the protein isolate from defective soybeans when compared to not defective soybean protein isolate. The flour, oil, and protein isolate obtained from defective seeds presented undesirable alterations for food industries. The utilization of defective soybeans will reduce the quality and yield of soybean processing when destined for oil and protein extraction.

TL;DR: It is noteworthy that some S. oryzae are able to recognize irradiated rice as distinct from control, and grains treated with UV-C had less acceptance and purchase intention by human panelists, mainly due to the odor attribute.
