Rice is one of the most important food crops for many countries around the globe. Around 60% of the world’s population depends on it for daily sustenance, especially in the East and Southeast Asian regions, where it is a dietary staple. Unfortunately, even though rice is regarded as such, a large portion of it still goes to waste due to challenges in post-harvest handling and management.
According to the United Nations’ (UN) Food and Agriculture Organization (FAO), farmers often lose around 10 to 37% of their yield because of several challenges in drying and storing after harvest. To help prevent all these, take a look at some challenges in said stages of rice post-harvest, and learn how you can navigate through them.
Among the common challenges cited by FAO when it comes to rice post-harvest handling is “rudimentary drying”. Drying is a critical process where grains’ moisture is reduced so that these are ready for storage. Any issue in drying can result in discoloration, mold growth, and ultimately, loss of grains. Proper drying, meanwhile, can result in proper storage of the world’s most important crop.
To understand how to properly dry rice, it is important to know and monitor its moisture content. Farmers usually harvest rice with a grain moisture of 24 to 26%. Then, they need to dry it up to 14% or less in order to be prepared for storage. Ineffective measurements of moisture content can lead to extra drying costs and a loss of grains.
Take note, though, that monitoring and preventing extra moisture content in your crops doesn’t end in the drying phase. You also have to do this during the storage stage.
Traditional drying methods, such as sun drying, are still being used today. However, these methods are not immune to the effects of inclement weather. The unpredictability of weather can result in the rewetting of rice. This could, in turn, lead to spoilage, discoloration, or mold growth.
To navigate through the challenge of unpredictable weather, use a drying system that can protect the paddy from rains and sudden changes in weather as well.
The challenge doesn’t stop with the drying of grains. Grains need to be stored properly to prevent loss due to moisture, microorganisms, insects, pests, and unpredictable weather.
As mentioned earlier, rice should be at a proper moisture level before these are stored to avoid loss. But monitoring moisture content shouldn’t stop there—rice moisture content should be maintained even during the storage period. Remember that moisture can be absorbed from the surrounding air. In addition to the air, sudden rains can also influence the moisture content of rice.
To solve these problems, make sure to utilize a storage system that is air-and-moisture tight. This will protect your grains from imbibing moisture and re-wetting.
Aside from moisture and inclement weather, insects and pests also play a destructive role in rice post-harvest management and handling. They can contaminate and cause spoilage to your paddy or grain, or feed on it. Fortunately, an effective storage system can also keep insects and pests away from the valuable crop.
These examples are just a glimpse of the many challenges in rice post-harvest management and handling. However, producers, traders, and handlers need not worry, as there are also a number of effective and affordable solutions that can help protect their commodities.
