Production of storage and dehydration (dehy) onions is increasing rapidly in the northcentral Oregon region of the Columbia Basin. Roughly circular patches of stunted onions have been observed in many fields and are often numerous and (or) extensive in area. Onions in these patches often exhibit symptoms typical of stubby-root nematodes, and Paratrichodorus allius has been collected from severa...

The onion is a low perishability product, but in long-term storage, postharvest losses occur due to some phytopathological and sprouting factors. The aim of this study was to evaluate the effect of storage in controlled atmospheres (CA) on onion cultivar “Sierra Blanca” for seven months. The onions were subjected to three treatments: 1 % O2 + 1 % CO2 (T1), 3 % O2 + 5 % CO2 (T2), both at 2.5 °C ...

Contact experiments have been performed between an onion lamel-lar phase and brine, in the SDS/octanol/brine system. Using video mi-croscopy we have studied the nonequilibrium behaviour of the swelling and dissolution process of onions. Experiments at T = 20 • C and 30 • C showed that temperature has a strong effect on their behaviour. At low temperature onions are observed to diffuse away from...

Onion maggot, Delia antiqua (Meigen) (Diptera: Anthomyiidae), is an important pest of onion, Allium cepa L., in northern temperate areas, especially in the Great Lakes region of North America Management of D. antiqua relies on insecticide use at planting, but insecticide resistance can cause control failures that threaten the long-term viability of this strategy. Delaying the time onions are pl...

Two onions (Sulfur-1 and Sulfur-4) cultivated with different sulfur applications were thermally processed to elucidate the effects of heat treatment on browning index and antioxidant activity. Sulfur-4 onion had higher sulfur content compared with the Sulfur-1 onion. After thermal processing, browning intensity was different between the two onions juices, with lower values observed for Sulfur-4...

• Significant correlations between age group and performance for FRs (r=0.55, p<0.001) and PDDs (r=0.56, p<0.001). 2. Truth-Value Judgment Task Methods •Participants: 4yo (18), 5yo (17), 6yo (19), 7yo (11). •Participants were told: “Cookie Monster really likes cookies, but he does NOT like onions.” They were shown pictures of (i) plates of cookies, (ii) onions, or (iii) both cookies and onions....

Although garlic and onions have long been associated with putative cardiovascular health benefits, the effects of different commercially available onions and level of intake have not been studied. Therefore, the aim of the present study was to evaluate the potential health benefits of raw onions using the pig as a biomedical model. Twenty-five female (Large White x Landrace) pigs were used in a...

To maintain high quality and to extend the shelf life of intact and minimally processed (removal of roots and compressed stem) green onions (Allium cepa×A. fistulosum), the potential benefits of controlled atmospheres (CA) and heat treatment were evaluated. Atmospheres of 0.1–0.2% O2 or 0.1–0.2% O2 containing 7.5–9% CO2 were the CA conditions that best maintained the visual appearance and prolo...

A simple method to fabricate high-quality nanoparticles including spherical carbon onions and elongated fullerene-like nanoparticles similar to nanotubes in large quantities without the use of vacuum equipment is reported. The nanoparticles are obtained in the form of floating powder on the water surface following an arc discharge between two graphite electrodes submerged in water. High-resolut...
