In order to evaluate the relationship between morphological characters in rice lines two populations at F3 generation were grown in research field of Agricultural Sciences and Natural Resource University, Sari, Iran, during 2012. Statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

there are different methods used for threshing of grain crops. usual threshers operate based on the impact force (in threshing unit) that may damage the grains. in another method named axial-flow, grain damage is less so these types of the harvesting machines are being used more than before. in this study one of the common rice threshers (model t30) locally made in ashtad company was modified t...

Metabolomics is widely employed to monitor the cellular metabolic state and assess the quality of plant-derived foodstuffs because it can be used to manage datasets that include a wide range of metabolites in their analytical samples. In this review, we discuss metabolomics research on rice in order to elucidate the overall regulation of the metabolism as it is related to the growth and mechani...

Diffusion-driven water uptake in a substrate (imbibition) is a subject of great interest in the field of food technology. This is a particular challenge for rice grains that are preprocessed to accelerate the water uptake, i.e., to reduce the cooking time. Rice preprocessing disrupts the mesostructural order of starch and induces a microporous structure in the grains. The mesoand microstructura...

Grain crops are an important part of the human diet, accounting for a third consumed calories. Throughout history, annual grain with high yields have been obtained through domestication. However, “annual” characteristic brings associated series economic and environmental disadvantages, such as soil erosion or low resources use, that can be solved if agriculture varieties evolves towards perenni...

results mycoflora profiles of fresh and stored rice grains showed that aspergillus species (37.3%, 40.7%) were the predominant fungal agents, followed by fusarium (21.6%, 16.2%), mucor (19.6%, 16.7%) and rhizopus (9.8%, 11.1%), respectively. in hplc analysis, most of the rice samples (96.7%) collected were found to be positive for fb1 with mean levels ranging from not detected to 56.2 mg/kg for...

Rice (Oryza sativa L.) is the most important crop all over the world. It is considered the main 19 food of 50% of the world population especially in Egypt. However, rice not only accumulates some of 20 heavy metals such as cadmium but also accumulate arsenate (As). Arsenic contamination in water and 21 food resulted in many implications for millions of people leading cancer. For that reason, th...

Background: Deoxynivalenol (DON) is a mycotoxin produced mainly by Fusarium graminearum in grains such as wheat and maize. The aim of this study was to evaluate the inhibitory effects of citrus flavanones including, naringin (NAR), hesperidin (HES), and neohesperidin (NEO) on deoxynivalenol production using Response Surface Methodology (RSM). Methods: The studied flavanones were extracted fr...
