What are the problems of post-harvest operation?
Physiological deterioration and Infections An increase in the rate of loss because of normal physiological changes is caused by conditions that increase the rate of natural deterioration, such as high temperature, low atmospheric humidity and physical injury.
What are the factors affecting post-harvest losses?
In general, post-harvest losses of fruits and vegetables is influence by many factors. These factors includes losses due to physical, physiological, mechanical and hygienic conditions. Fruits and vegetables are mainly characterized by high level metabolic activities and known to posse’s short shelf life.
How can post-harvest losses be improved?
Here, Deltsidis offers six pointers in the postharvest process that if you employ, can help you avoid suffer major losses.
- Assess Maturity.
- Check Your Water Quality.
- Check Your Water Temperature.
- Avoid Injury.
- Keep Your Produce Cool.
- Proper Storage.
What are the barriers or drawback in the post harvest handling practices here in the Philippines?
Some of the major constraints in the development of postharvest technology are as follows: lack of R & D budget (less than 1% of GNP), lack of infrastructure support, small landholdings of farmers, weak farmers’ organizations / cooperatives, and lack of government policy and implementation.
What is the importance of post harvest technology?
Importance of Post-harvest technology lies in the fact that it has the capability to meet food requirement of growing population by eliminating losses making more nutritive food items from raw commodities by proper processing and fortification. Post-harvest technology has potential to create rural industries.
What factors are responsible for post-harvest deterioration of fruits and vegetables?
Main causes of postharvest loss include lack of temperature management, rough handling, poor packaging material, and lack of education about the need to maintain quality [7].
What are the causes of quality defects in perishable crops?
Some examples are:
- Inadequate harvesting, packaging and handling skills.
- Lack of adequate containers for the transport and handling of perishables.
- Storage facilities inadequate to protect the food.
- Transportation inadequate to move the food to market before it spoils.
- Inadequate refrigerated storage.
What is Post Harvest engineering?
Post-harvest engineering and technology is an application of engineering principles for development of post harvest machinery for various post harvest operations. It also comprises practices of various operations to serve food to the countrymen after harvesting.
How can you reduce losses and improve the quality of fruit and vegetables after harvest?
Pruning provides favorable conditions for fruit growth; proper pruning reduces competition between fruit, enables more light to reach the plants, prevents diseases and thus reduces losses.
Why is it important to study postharvest physiology and technology?
Postharvest physiology and technology has been key to maintaining and extending the shelf-life of perishables and reducing food losses.
