Onion Storage Sturcture ,Process & Benifits

Onion Storage Structure In Maharashtra:

Onions can be stored in various structures depending on the scale of operations and available resources.
few common storage structures used for onions in Maharashtra:

Traditional Storage Sheds:
These are simple, well-ventilated structures made of bamboo, wooden crates, or mesh walls. They provide protection from direct sunlight and allow for adequate airflow to prevent moisture buildup.

Ventilated Storage Rooms:
These are enclosed rooms or buildings equipped with proper ventilation systems to regulate temperature, humidity, and airflow. They may have adjustable vents or fans to ensure optimal conditions for onion storage.

Cold Storage Facilities:
Larger-scale operations often use refrigerated storage rooms or warehouses. These facilities have temperature and humidity control mechanisms to extend the shelf life of onions. Cold storage facilities are especially beneficial for long-term storage or when onions need to be stored over several months.

Onion Storage Process followed by Farmers & FPC’s:

Curing: After harvesting, onions need to undergo a curing process to dry the outer skins and promote proper storage. Curing helps toughen the outer layers and reduces the risk of spoilage. It involves spreading onions in a well-ventilated area with good airflow for a few weeks until the outer skins become dry and papery.

Sorting and Grading: Before storage, onions are sorted and graded based on size, quality, and maturity. Damaged or diseased onions are removed to prevent the spread of spoilage.

Storage Conditions: Onions require specific storage conditions to maintain quality and prevent deterioration. The optimal conditions for onion storage are:

Temperature: Onions should be stored at temperatures between 0°C to 4°C (32°F to 39°F) for long-term storage. Short-term storage at slightly higher temperatures, around 7°C to 10°C (45°F to 50°F), is acceptable.
Humidity: Onions prefer a relative humidity (RH) level of 60% to 70%. Proper humidity control helps prevent shriveling or sprouting.
Ventilation: Good airflow is crucial to prevent moisture buildup, reduce the risk of fungal growth, and maintain onion quality. Proper ventilation is achieved through the design of storage structures or through the use of fans or vents in storage rooms.

Onion Storage Benefits For Farmers & FPCs:

Proper onion storage offers several benefits, including:

Extended Shelf Life of Onion: Adequate storage conditions can significantly prolong the shelf life of onions, allowing them to be stored and consumed over an extended period.

Market Availability of Onion: Proper storage enables farmers and suppliers to have a consistent supply of onions throughout the year, even during periods of low or off-season production.

Price Stabilizationof Onion: By storing onions during periods of high production and releasing them gradually during periods of low production, price fluctuations can be minimized, benefiting both producers and consumers.

Reduced Lossesof Onion: Effective storage practices help reduce losses due to spoilage, sprouting, or disease, thereby maximizing profitability for farmers and suppliers.

Flexibility in Marketing of Onion: Stored onions can be marketed and sold at opportune times, allowing producers to take advantage of favorable market conditions and potentially secure better prices.
