Nanotechnology: A New Frontier in Post-Harvest Management

-



Nanotechnology is the art and science of manipulating matter at the nanoscale, where properties and phenomena differ significantly from those at a larger scale. By working with individual atoms and molecules, scientists and engineers can create materials and devices with extraordinary properties and capabilities. This cutting-edge field is transforming industries, including agriculture, with applications that promise to revolutionize food production and preservation.1,2.

Understanding the Challenges of Post-Harvest Management

Post-harvest losses are a significant global issue, leading to economic losses, food wastage, and nutritional deficiencies. Several factors contribute to these losses, including:

  • Perishable nature of produce: Fruits and vegetables have a limited shelf life.
  • Improper handling and storage: Damage during harvesting, transportation, and storage accelerates spoilage.
  • Pathogens and pests: Microorganisms and insects can cause rapid decay.

 

The Role of Nanotechnology

Nanotechnology offers innovative solutions to address these challenges. Here are some key applications 3:

  • Nano-coatings:
    • Extend shelf life by creating an impermeable barrier against moisture, oxygen, and pathogens.
    • Improve product appearance and sensory qualities.
    • Enhance the delivery of active compounds like antioxidants and antimicrobials4.
  • Nano-sensors:
    • Monitor product quality parameters such as ripeness, temperature, humidity, and ethylene levels.
    • Enable real-time tracking and control of storage conditions.
    • Detect early signs of spoilage or contamination.
  • Nano-packaging:
    • Improve barrier properties to maintain product freshness.
    • Enhance packaging material strength and durability.
    • Provide active packaging with antimicrobial or antioxidant properties.
  • Nano-fertilizers and pesticides:
    • Deliver nutrients and pesticides more efficiently at the cellular level.
    • Reduce environmental impact by minimizing chemical usage.

Benefits of Nanotechnology in Post-Harvest Management

  • Reduced food waste: By extending shelf life and preventing spoilage.
  • Improved food safety: By controlling pathogens and contaminants.
  • Enhanced product quality: By maintaining freshness, flavor, and nutritional value.
  • Increased economic returns: By reducing post-harvest losses and increasing market value.
  • Sustainable agriculture: By minimizing the use of chemical inputs.

 

Challenges and Future Outlook

While nanotechnology holds immense potential, there are challenges to overcome, such as:

  • High production costs
  • Safety concerns regarding the potential impact of nanoparticles on human health and the environment
  • Regulatory hurdles for the commercialization of nanotechnology-based products

Despite these challenges, ongoing research and development efforts are addressing these issues. As nanotechnology matures, it is expected to become increasingly integrated into post-harvest management practices, leading to a more sustainable and efficient food supply chain 3,5.

Silage preparation and fodder preservation methods.

-
Image
  Silage is a product where any green plant material is kept in a place where it can ferment in the absence of air that contains 40-45% of water. Silage is a green succulent. When the green fodders are plentiful, it is preserved as silage for farm animals. The process of conserving green fodder is called ensilage. Green silage is a palatable and nutritious type with a Dry matter of 25-35%. During this process, the fermentation of sugar forms acids and it breaks down some of the forage proteins into simpler compounds, including ammonia.   Crops: Crops that are rich in soluble sugar is suitable for ensiling. Ex: Maize, natural grass, sogam 3-3.5% of molasses is added. Stage of harvesting: Crops should be harvested between the flowering and milk stages (50%). Silo: Silo is an air tied structure designed to store and preserve high-moisture fodder as silage. When it comes to pit silos, pits are dug 2.4 to 3cm in depth and space is required for 400 kg of fodder. ...

What is Biosystems technology

-
Image
                                   Basically, biology means studying life. This word derives from the Greek word where “bios” is life and “ logos” is study. system is a collection of parts that work together to complete a specific task. Hence you know that biosystem is not a simple thing. Yeah, it is a complex topic where we can talk and learn many aspects. Once you separate the parts of the car into the engine, tyers, body we can say each part as a car but once these parts are integrated, it is a car, and it functions as a car. This is very similar to a system and biosystem also functions like this. Another example is a living cell. Life is marvelous. Animals, plants and fungus are the living things that are visible. Bacteria, virus and other microorganisms are living things that are not visible to our naked eye. There are a few characteristics that are displayed by living things (life). By these....
