Abstract:

Onions are an important vegetable, but storing them properly is a challenge. Temperature and humidity play a big role in keeping onions fresh. High temperatures cause moisture loss, shrinkage, and sprouting, while very low temperatures can damage their texture. If humidity is too high, onions can develop mold and bacterial infections. If it is too low, they dry out and become lightweight. This review explores how temperature and humidity affect onion storage. It also discusses methods to improve storage, such as controlled atmosphere storage, special packaging, drying, and fumigation. Using th

Abstract:

The second goal of sustainable development is ending hunger, achieving food security improving nutrition, and promoting sustainable agriculture. Improved storage system is a part of sustainable agriculture. This research aimed to design and develop an aerated storage system for onions and examined the extent of losses to assess the efficacy of the storage system. Unseasonal rainfall and adequate storage facilities result in quick sales and spoilage of onions. A huge amount of onion is damaged due to a lack of proper post-harvest actions like storage, transportation, temperature control, and hu

Abstract:

Onion (Allium cepa L.) is an important and familiar spice as well as vegetable crop throughout the world. Storage rot due to various diseases caused by bulb rotting fungi is a major constrain for storing onion year-round in Bangladesh. The fungi associated with onion collected from different markets of Mymensingh, Naogaon and Sathkhira districts of Bangladesh were studied aiming to record the incidence of storage diseases as well as storage variability and conditions on disease incidence of onion. Disease incidence was recorded from storage of the retailers in two local varieties of onion,viz.

Abstract:

A 3-yr study with eight different onion cultivars, Allium cepa, was conducted to determine the association of water-soluble carbohydrates (WSC) with the storability of the bulbs. Onion bulbs were harvested in the fall of 1983, 1984 and 1985, and sample bulbs were analyzed for WSC. Water-soluble carbohydrates of onion bulbs consisted of a series of oligofructans, the maximum degree of polymerization (DP) being between 10 and 15, in addition to fructose, glucose and sucrose. Fructan concentration of onion bulbs harvested in 1985 decreased during storage. Onion cultivars with a short storage life

Abstract:

Plant pathogens present a major challenge to crop production, leading to decreased yield and quality during growth and storage. During long-term storage, healthy onions can develop diseases from latent pathogen infections. This poses a challenge for onion growers because infected bulbs without visible symptoms can lead to significant crop losses during the growing season. In this study, we aimed to isolate and identify Fusarium species from yellow onion bulbs (Allium cepa L.) that developed disease symptoms during storage.

Abstract:

Exogenous growth regulators (GRs) play a crucial role in alleviating water stress and sustaining crop yields in water-stressed areas. However, their effects on onions post-harvest quality, particularly post-monsoon onion—often preferred for long-term storage—were never studied. Therefore, this led us to investigate the interaction between water stress and GRs on the physiochemical and functional quality attributes of onions during long-term storage (9 months, at 25 ± 1 °C and 65 ± 5% RH). Onion crop was raised under four water stress levels i.e., 1.00–0.85, 0.84–0.70, 0.69–0.40, and 0.39–0.10

Abstract:

Field experiments were conducted from 2008 through 2010 near Lyons, GA, to develop integrated weed management systems for organic Vidalia® sweet onion (Allium cepa) production. Treatments were a factorial arrangement of summer solarization, cultivation with a tine weeder, and a clove oil herbicide. Plots were solarized with clear plastic mulch during the summer fallow period before transplanting onion. Cultivation treatments were twice at 2-week intervals, four times at 2-week intervals, and a noncultivated control. Herbicide treatments were clove oil plus vinegar, clove oil plus an emulsified

Abstract:

Fall onions, grown for their long shelf life, have become popular both in domestic and export market. Sixty cultivars of onion from 14 major seed companies were grown in Quincy, Wash., and were analyzed for their flavor, quality, and anticarcinogenic flavonol, quercetin. The highest quercetin concentration (in mg·kg–1 fresh weight) was observed in the red onion `Feugo' (495.6) followed by `Tango' (396.8), while the least amount was in the yellow onion `Pinnacle'(152.5). The pyruvic acid content varied from 1.5 to 18.7 mmol·g–1 and total sugar (glucose, fructose, and sucrose) levels ranged from

Abstract:

Botrytis aclada and other Botrytis spp. can cause neck rot on onions, a storage disease that normally is very difficult to detect at harvest using traditional isolation techniques. Sequence characterized amplified region primers (BA2f/BA1r) were designed based on a previously cloned and amplified DNA fragment for direct amplification of isolates of Botrytis spp. associated with neck rot of onions. Digestion of the polymerase chain reaction (PCR) amplification product with the restriction enzyme ApoI makes it possible to distinguish the five groups: Botrytis aclada types AI and AII (B. allii);

Abstract:

In Depression-era South Georgia, truck farmers experimenting with onion planting found that their crop emerged unusually sweet, due to the region's climate and particular soil content. But what gave Vidalia onions a unique flavor—their low sulfur and high water content—also rendered them nearly impossible to market, as the vegetable spoiled much quicker than regular onions. In their seventy-year quest to overcome the onion's natural limitations, Georgia growers would transform their formerly insular region into a hub of global supermarket capitalism.

Abstract:

Onion (Allium cepa L.) is an economically important vegetable in the United States. Though considered a minor crop in terms of total acreage, onions have high value when compared to other crops and, nationally, their value approaches $800 million. Because harvested onions are routinely stored for long periods, disease can be a major obstacle to the industry. The primary disease reported in stored onions is botrytis neck rot caused by the fungus Botrytis allii (syn. B. aclada). Losses from neck rot can approach 35% of the stored crop. In order to accurately quantify the level of B. allii inocul

This study investigated the effect of gaseous ozone on the decay and quality of onion bulbs during storage at 2 °C and 70% relative humidity for two months. Gaseous ozone was adjusted to a concentration of 1.27 ± 0.024 ppm in the storage room by generating a high voltage discharge in air. After two months of storage, gaseous ozone significantly reduced the counts of aerobic bacteria (e.g., Rahnella aquatilis) and fungi (e.g., yeast and mold) in the onion bulbs by 4 log (CFU g−1) a

To evaluate LF as a potential means of assessing flavor quality, two onion cultivars were greenhouse-grown and the bulbs stored for 4 months at 3 ± 1 °C, 70% relative humidity. Onions were evaluated at monthly storage intervals for LF development in bulb macerates following a 120 seconds incubation time. When LF was compared to amounts of 1-PRENCSO hydrolysis, we found that LF was severely underestim

The protrusion of sprouts is a major cause of loss of dry onions (Allium cepa L.) during extended storage. Sprouting is conventionally suppressed by treating onions with maleic hydrazide (MH) before harvest. More recently, ethylene was reported to inhibit sprout growth in stored onions, but commercial use of ethylene has been limited. Therefore, the objective of this study was to assess the effectiveness of ethylene on sprout suppression of five commercial cultivars of onions during storage and compare its effectiveness with and without MH treatment.

Storage at 20°C of skinned onion decreases sligthly pungency, however three weeks storage at 0-2°C did not change it. Other results indicate that freezing at -25°C, and followed thawing led to large losses - reaching 75% of pungency found in the onion taken to the process. Storage of the fro
