Okra has a very high respiration rate at warm temperatures and should be promptly cooled to reduce field heat and subsequent deterioration. Okra which is in good condition can be stored satisfactorily for 7 to 10 days at 45 to 50°F (7 to 10°C). At higher temperatures, toughening, yel- lowing, and decay are rapid.
What are the post harvest handling processes?
In agriculture, postharvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. The instant a crop is removed from the ground, or separated from its parent plant, it begins to deteriorate.
What are the 5 handling practices for post harvest operation?
Handling practices like harvesting, precooling, cleaning and disinfecting, sorting and grading, packaging, storing, and transportation played an important role in maintaining quality and extending shelf life.
What is post harvest handling of vegetables?

What is post harvest handling of corn?
According to post-harvest corn handling includes harvesting, shelling, drying, transporting and storing. [34, 43] reported that the shrinkage of corn yield in post-harvest activities (excluding storage) ranged from 1.2 to 5.2%.
What are the objectives of post-harvest handling?
The three main objectives of applying postharvest technology to harvested fruits and vegetables are: to maintain quality (appearance, texture, flavor and nutritive value) to protect food safety, and. to reduce losses between harvest and consumption.
What is the post-harvest management of fruits and vegetables?
Postharvest management is a set of post-production practices that includes: cleaning, washing, selection, grading, disinfection, drying, packing and storage.
What is postharvest operation and postharvest handling?
The field of postharvest practices addresses issues of handling, transportation and temperature control for crops after harvest. Good postharvest handlng is critical to reducing postharvest losses of fresh produce, to maintain quality, preserve nutrient content, and earn higher prices at market.
What are the main elements of the post harvest system?
technical activities: harvesting, field drying, threshing, cleaning, additional drying, storage, processing; economic activities: transporting, marketing, quality control, nutrition, extension, information and communication, administration and management.
What are post harvest equipments?
What is Post Harvest Equipment? The post harvest techniques save time and labour cost in enhancing the marketability and quality of products also. The tools used in this technology are called post harvest equipment. These machines provide a reach to avoid post harvest losses.
What is post harvest handling of perishable crops?
Only use cleaned and, as necessary, sanitized packing or transport containers. Cleaning and washing. Some commodities—in particular, root and tuber vegetables and leafy greens grown close to the soil—may need or benefit from cleaning to remove soil, small adhering insects, and other contaminants.
What is the meaning of post harvest?
Meaning of post-harvest in English
happening or existing after a harvest (= the activity of cutting and collecting crops): The aim is to minimize post-harvest crop loss.
What is the post harvest of tomato?
Tomatoes are easily damaged after harvest. The damage was caused by physiological damage, mechanical damage as well as pests and diseases. Potential loss of tomato fruit quality during post-harvest handling ranges from 30-50%.
What is harvesting and processing?
Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season.
What methods are used for harvesting and storing corn?
Shelled corn or earcorn harvested early at 25–33% moisture and stored in an air-tight (sealed) silo is an excellent animal feed (if it is of high quality). If it is finely ground and firmly packed, high moisture corn can even be stored in conventional silos or trench silos.
What are the common factors causes of post-harvest losses in grain crops?
Causes of post-harvest loss in this stage include limited availability of suitable varieties for processing, lack of appropriate processing technologies, inadequate commercialization of new technologies and lack of basic infrastructure, inadequate facilities and infrastructure, and insufficient promotion of processed
Why essential postharvest handling is important to all commodity?
The three main objectives of applying postharvest technology to harvested fruits and vegetables are: 1)to maintain quality (appearance, texture, flavor and nutritive value) 2) to protect food safety, and 3) to reduce losses between harvest and consumption.
What is the importance of postharvest 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.
Why packaging practices is important in postharvest handling?
A good package should protect the product during storage and transit, facilitate temperature management, protect from water loss, be compatible with any special treatments required by the product, and be compatible to existing handling systems.
What is post harvest management and value addition of fruits and vegetables?
Post harvest losses in fruits and vegetables are very high (20-40%). About 10-15% fresh fruits and vegetables shrivel and decay, lowering their market value and consumer acceptability. Minimizing these losses can increase their supply without bringing additional land under cultivation.
What are the post harvest changes in fruits?
Postharvest storage initiates fruit senescence—the effects of which on biological processes are unavoidable and largely negative. Senescence leads to protein, lipid and nucleic acid degradation and cell dysfunction, disintegration and death [5].
