Postharvest Biology and Technology: Postharvest Technologies

The primary objectives in postharvest handling are to keep the produce cool, slow down transpiration and other chemical changes, and prevent physical damages such as bruising and impact in order to delay deterioration.

Postharvest technologies are there to stimulate agricultural production, prevent postharvest losses, boost nutritional value, and increase value of production. Continue reading “Postharvest Biology and Technology: Postharvest Technologies”

Plant Diseases: A Primer on the Nemesis of Every Farmer (Part 2)

For us to be able to come up with an effective plant disease management, we need to first be
aware of how diseases develop in a plant. What really causes plant diseases? What can we do
about these diseases?

We have discussed in the first part of this blog about the disease agents. Aside from these
disease agents (biotic and abiotic), we will be needing to discuss the other elements which
should be present to have plant diseases. Also, we’ll briefly look at some ways to prevent
harvest losses due to plant diseases later on.

Here are Some Insights on Post-Harvest Losses

Did you know that a third of all produced food for human consumption is lost or wasted?

It is for that reason why it is important even for the smallholder farmers to be
knowledgeable of the necessary steps and latest post harvest products and technologies
to prevent losing large portions of their produce.

We at BioNovelus are proud of our product, the CR-10. It is organic non-toxic, and
biodegradable. It targets microbial cell without harming produce or people because it is
developed from a protein found in the immune system of the plants. CR-10 works with
nature to protect plants from harmful microorganism.

Unlike with other products, bacteria and fungi cannot develop resistance to CR-10. By
using this, packers and exporters don’t need to use more products to protect their
produce all the time. They can reduce waste, extend shelf life and expand to new
markets with this powerful solution.

Keep reading and learn more about some facts you may not know about post harvest
losses.

 According to FAO, a whopping 1.3 billion tons of food produced for human
consumption is lost or wasted worldwide every year.

Fruits and vegetables make most of this wastage. In Sub-Saharan Africa, a third
of their total produce are lost after harvest. These crops can be easily damaged
or spoiled while being harvested, packed, stored and transported.

 Proper training and access to post harvest products and technologies have
a huge impact on the safety of food for consumption.

It is common for farmers to get the damaged produce for their consumption
because the high quality ones can be sold at a higher price. If they have access
to trainings and technologies that improve post harvest handling, they can get
more aware of the risks of consuming damaged produce.

 Improving the post harvest handling practices will allow farmers to gain
more profit.

Farmers are able to export more food for consumption while gaining more profit.

This is a win-win solution for both the farmers and the consumers. This has a
positive impact to the economy as well.

The Benefits of Organic Farming

The usage of chemical products has become the trend in agriculture. The benefits of
these chemical products are so great that any harm it may cause became unnoticeable.

However, because the problems that come along with this conventional farming have
now been exposed, many are now going back into organic farming again.

What are these problems associated to chemical products used in farming?

 Health related diseases (cancerous diseases)

 Environmental issues (Water and land pollution)

 Impact on the welfare of animals

What then is organic farming?

In organic farming, all the process involved are natural ways. All materials used in the
process of farming are made of organic or biological materials. Synthetic materials are
never used in any part of the process. This makes organic farming a healthier choice to
humans, animals and the environment.

Here are some of the most sensible reasons why we should make the switch to organic
farming.

1. Farmers will have reduced exposure to harmful chemicals.

The most affected groups of people by pesticides are the families of farmers.

2. Increased nutrition and reduced chemical contamination for consumers.

Studies show that organic foods have higher amount of nutrients compared to
those products from conventional farming.

3. Children will have less exposure to chemical pesticides.

Since a child’s body is still developing, it can be hard to defend itself from toxic

4. Organic farming builds healthy soil.

If soil is constantly exposed to harmful chemicals, it is more likely that the soil
cannot withstand it. Soil erosion is being reduced as well.

5. Organic farming supports the conservation of healthy water.

Almost everything in this planet is dependent on water. With organic farming, the
conservation of good quality water resources is strengthened.

6. Organic farming supports the welfare of animal health.

Conventional farming has contributed to the loss of habitats of many animals.

This issue can gradually be resolved when organic farming is implemented.
Moreover, animals can safely live nearby agricultural fields.

10 Tips to Prevent Post-Harvest Losses

In the more recent years, one of the major global problems is secured food supply for
the exponentially rising population. Based from FAO’s findings, in order for food to be
enough for the increasing human population, food production needs to grow by 70%.

One of the solutions to this global crisis is to combat post-harvest losses. This post will
brief you on some of the basic harvest handling tips to avoid further losses in the
production of crops.

1. Post-harvest quality planning must be accomplished.

There should be a set of good agricultural practices (GAP) to be developed for
each specific crop. Everything from the land use, water quality, field sanitation,
workers’ dynamics and operations and other factors should be highly considered.

2. Each program that has been pre-planned must be carefully executed and
implemented during harvest.

3. It is best to perform harvest during low-temperature time of the day.

This will ensure low product respiration.

4. Avoid the harvested products to be in direct contact with the sun.

Always keep them cool.

5. Make sure that there is good airflow where the crops are stored.

Poor ventilations speeds up the decaying process.

6. Never let the produce be bruised or crushed.

Careful handling must always be observed.

7. It is not advisable to mix some of the bad crops in a pack of good ones.

This will just spoil the whole bunch.

8. Use only clean and dry containers for transport.

Avoid contamination in the crops.

9. Organic products like CR-10 can be used to protect the quality of the crops
without compromising the health of consumers.

10. High quality cooling systems are good investments in this line of field.

After all, temperature is the single most important factor to consider to maintain post-
harvest quality.

The Primary Causes of Post-Harvest Losses

One of the most serious issues in farming are post-harvest losses. They are caused by
many factors which will be discussed here in this post.This is an alarming problem
because it does not only affect the profitability of farmers but it also affects the supply
chain and therefore the consumers. To put it simply, post-harvest losses can result to
large-scale issues so getting to the root of it should be done.

There are many contributors to post-harvest losses and we will be identifying these as
they go from production to the market.

1. PRE-HARVEST

Before the actual harvest procedure, some of the factors that contribute to
damage later on occurs during pre-harvest or when the crops are still on the
farm.

 Inadequate water supply: Plants need only enough water to survive. Too
much or too little amount of water can cause plants to whither.

 Too much use of fertilizer: Fertilizer can sometimes negatively affect the
development of the plants. This will also affect the post-harvest quality of
the produce on the latter stage of production.

 Unsatisfactory weed control: Weeds can be harmful to plants as they
compete for the necessary nutrients with the crops.

2. POST-HARVEST

After harvest, the shelf life of each produce shortens more quickly.

 Fruits and vegetables continue to lose their water contents. Water is vital
for all plants to survive. Without water, these plants dies and gets spoiled.

This makes it completely normal for these produce to gradually die after
harvest.

 Poor ventilation: Without air supply, respiration among plants stop causing
them to proceed to fermentation.

 Inability to clean and protect the crops.

3. MARKET

In transferring of goods to the market, damage is almost unavoidable. There are
more factors that contribute to losses in the marketing stage.

 Bad containers

 Over-packaging or under-packaging

 Extreme temperature

 Presence of contaminants

 Careless handling or transport

What Happens After Harvest

The work of farmers and workers in the agricultural field doesn’t end after successfully
harvesting their crops or produce. At the end of the harvest, there are still some steps to
finish in order to secure their products.

One of the main concerns of farmers is the damage that can happen to the produce
after the harvest.

To walk you through the factors in the post-harvest procedure, here is a short list.

1. Field tillage

Fieldwork just doesn’t stop in a farm. Farmers use heavy-duty tools and
equipment that can smoothen fields up. Their goal is to remove weeds and break
down soil.

2. Field spraying

After the harvest, farmers also need to make sure that weeds are controlled. The
best crops thrive in weed controlled fields so this one is important.

3. Equipment cleanup

Farmers’ equipment get really dirty and muddy and for it to operate properly, they
should be cleaned up as well. Usually, farmers employ industrial cleaning
equipment to do the job.

4. Product cleanup and protection

This is one the most critical part of the post-harvest process. The primary goal is
to preserve the harvested produce until they reach the market. Luckily, there are
organic products like CR-10 that is perfect for this application.

CR-10 protects the produce, extending its shelf-life and increasing the volume
that reaches the market.

5. Sorting and Packaging

Good produce is separated from bad or damaged ones. They are packaged in
special methods to further prolong shelf life.

6. Marketing

In the marketplace, each trader has different standards. So it’s best to have well-
packaged and good quality produce to delivered to the market.
