10 Questions
Explain the cost implications of preventing postharvest losses compared to producing additional amount of produce.
The cost of preventing postharvest losses after harvest is generally less than the cost of producing a similar additional amount of produce. Reduction in postharvest losses is a cost-effective means of preserving fresh produce.
Why are fruits and vegetables considered more perishable than other agricultural commodities after harvest?
Fruits and vegetables are considered more perishable because they are living commodities even after harvest and continue to respire, transpire, and carry out other biochemical activities, leading to quicker deterioration compared to other agricultural commodities.
Explain the concept of postharvest losses and their types.
Postharvest losses refer to the deterioration in harvested fresh produce from the time of harvesting till they reach the consumer. The types of losses include quantitative loss, which is the reduction in weight due to moisture loss and loss of dry matter by respiration, and qualitative loss, which is the deterioration in freshness leading to loss of consumer appeal and nutritional loss.
What are the factors contributing to postharvest losses in fresh produce?
The factors contributing to postharvest losses in fresh produce include moisture loss, respiration, freshness deterioration, loss of consumer appeal, and nutritional loss such as vitamins, minerals, and sugars.
Why is reducing postharvest losses important in the agricultural sector?
Reducing postharvest losses is important in the agricultural sector because it helps in preserving the quality and quantity of fresh produce, minimizing economic losses, and ensuring food security by reducing wastage.
Match the following postharvest loss types with their descriptions:
Quantitative loss = Reduction in weight due to moisture loss and loss of dry matter by respiration Qualitative loss = Freshness deterioration leading to loss of consumer appeal and nutritional loss including loss in vitamins, minerals, sugars, etc. Preventing losses after harvest = Cost is generally less than producing a similar additional amount of produce Reduction in postharvest losses = A complementary means to reduce costs
Match the following activities with their characteristics in postharvest handling:
Respiration and transpiration = Continued biochemical activities in fruits and vegetables after harvest Client-side scripting for web applications = JavaScript Styling web pages = CSS Database queries = SQL
Match the following statements with their corresponding information related to postharvest handling:
Living commodities after harvest = Fruits and vegetables More perishable compared to other agricultural commodities = Fruits and vegetables Deterioration occurs quantitatively and qualitatively = Harvested fresh produce Losses from harvesting to reaching the consumer = Postharvest losses
Match the following terms with their meanings in postharvest handling:
Respiration = Biochemical process in fresh produce leading to dry matter loss Transpiration = The process of moisture loss in fresh produce Nutritional loss = Loss in vitamins, minerals, sugars, etc. Consumer appeal = Freshness and attractiveness to consumers
Match the following cost implications with their descriptions in postharvest handling:
Cost of preventing losses after harvest = Generally less than cost of producing a similar additional amount of produce Reduction in postharvest losses = Complementary means to reduce costs Importance of reducing postharvest losses = Cost-effective and beneficial for the agricultural sector Complimentary means = Reducing postharvest losses
Study Notes
Cost Implications of Preventing Postharvest Losses
- Preventing postharvest losses can be more cost-effective than producing additional amounts of produce
- Reducing postharvest losses can lead to significant cost savings and increased revenue for farmers
Perishability of Fruits and Vegetables
- Fruits and vegetables are more perishable than other agricultural commodities due to their high water content, respiration rate, and susceptibility to spoilage
- These characteristics make them more prone to degradation and decay after harvest
Postharvest Losses
- Postharvest losses refer to the reduction in quantity or quality of agricultural products after harvest, resulting in economic losses
- Types of postharvest losses include:
- Physical losses: damage to produce during harvesting, handling, and storage
- quantitative losses: reduction in produce quantity due to spoilage, decay, or pests
- qualitative losses: reduction in produce quality due to damage, decay, or contamination
Factors Contributing to Postharvest Losses
- Inadequate handling and storage practices
- Poor infrastructure and facilities
- Inadequate training and skills of farmers and handlers
- Inadequate management and oversight
- Pests and diseases
- Climatic and environmental factors
Importance of Reducing Postharvest Losses
- Reducing postharvest losses can increase food availability and reduce food insecurity
- Reducing postharvest losses can increase farmer incomes and revenue
- Reducing postharvest losses can reduce the environmental impact of agriculture
Postharvest Loss Types and Descriptions
- Physical losses: damage to produce during harvesting, handling, and storage
- Quantitative losses: reduction in produce quantity due to spoilage, decay, or pests
- Qualitative losses: reduction in produce quality due to damage, decay, or contamination
Postharvest Handling Activities and Characteristics
- Harvesting: careful selection and collection of ripe produce to minimize damage
- Handling: careful transportation and handling of produce to minimize bruising and damage
- Storage: controlled storage conditions to slow down spoilage and decay
Postharvest Handling Statements and Information
- Proper postharvest handling can reduce losses and maintain produce quality
- Improper postharvest handling can lead to significant losses and reduction in produce quality
Postharvest Handling Terms and Meanings
- Cooling: reducing the temperature of produce to slow down spoilage and decay
- Packaging: protecting produce from damage and contamination during handling and storage
Cost Implications of Postharvest Handling
- Reducing postharvest losses can lead to significant cost savings and increased revenue for farmers
- Improper postharvest handling can lead to increased costs and reduced revenue for farmers
