What are the factors that affect the quality of fruits and vegetables?
Post-harvest life of fruits and vegetables is governed by water content, respiratory rate, ethylene production, endogenous plant hormones, and exogenous factors such as microbial growth, temperature, relative humidity and atmospheric compositions.
What factors affect fruit quality?
The combination of these factors includes genetic, environmental, cultural practices, irrigation, packaging, pre-cooling, storage, transportations, etc. In this paper, we provide a review of studies on how pre-harvest and post-harvest factors influence the post quality of fruits.
What are the pre-harvest factors?
Pre-Harvest factors
- Genetic / variety.
- Light.
- Temperature.
- Humidity.
- Mineral nutrition.
- Water relation/ Irrigation.
- Canopy manipulation.
- Rainfall.
What are the factors that influence the quality of agricultural produce?
Among these are soil factors, such as pH, available nutrients, texture, organic matter content and soil-water relationships; weather and climatic factors, including temperature, rainfall and light intensity; the crop and cultivar; postharvest handling and storage; and fertilizer applications and cultural practices.
What are the preharvest factors affecting quality?
The pre-harvest factors influencing postharvest quality are frequency of irrigation, use of fertilizers, pest control, growth regulators, climatic conditions like wet and windy weather, natural climates such as hailing, high wind velocity, heavy rainfall, and tree conditions (age, training pruning, light penetration.
What are the factors affecting vegetable quality?
Climatic factors, in particular temperature and light intensity, greatly impact on the nutritional quality of fruits and vegetables. Consequently, the location of production and the season in which plants are grown can determine their ascorbic acid, carotene, riboflavin, thiamine, and flavonoid contents.
What determines the quality of vegetables?
Quality of fresh fruits and vegetables is generally based on the chemical composition or physical characteristics or a combination of these two factors. Attributes of interest to the consumers are visual appearance, texture/firmness, sensory, nutritional and food safety.
What is the importance of preharvest modifiers of quality?
3 Main Reasons: to prevent or correct minor element deficiencies with nutritional sprays as part of the mineral nutrition program. to control diseases, insects and mites with pesticides.
What are the factors affecting vegetable production?
In vegetables, production depends on soil and environment. In soil PH, soil moisture, soil humidity, soil texture, and soil fertility are the needs for good vegetables. Other than temperature, rainfall, humidity, and light intensity are also need for vegetable production.
What are the main causes of postharvest losses in fruits and vegetables?
1.2 Causes of losses vary widely
- Market demand for the products he will grow; he must know the market and his buyers.
- Cultivation.
- Harvesting and field handling.
- Packing or packaging.
- Transport.
- Market handling; possibly storage or refrigeration.
- Sales to consumers, wholesalers or agents.
- Perishability of the produce.
How does quality of vegetables affect harvests?
Quality characteristics such as texture, fiber and consistency are greatly affected by stage of maturity at harvest. Fruits and vegetables that are harvested while immature are highly susceptible to shriveling and mechanical damage. Fruits and vegetables harvested at an overripe stage often have poor texture and flavor …
What two factors determine the quality of fresh fruit?
What two factors determine the quality of fresh fruit? Ripeness and maturity. Immature fruits have not reached full size and have poor color, flavor, and texture. Ripe fruits give slightly when pressed.
What affects post harvest quality of fruits and vegetables?
Pre Harvest Factors Affecting post harvest quality of fruits and vegetables Fruits and vegetables provide nutritional security and generate income to growers. Production practices, contribute to the good quality of produce. Once the produce is harvested, it is not possible to improve its quality
What factors affect the quality of fruit?
Low light intensity increases postharvest disease incidence. 3.Relative humidity: Relative humidity plays an important role in determining fruit quality. Higher relative humidity reduces water and Calcium movement into the fruit.
What factors affect the quality of tomatoes after harvest?
Postharvest Factors Affecting the Postharvest Quality of Tomatoes After harvesting, the fruit still remains alive and performs all functions of a living tissue. The climacteric burst of ethylene which makes the fruit palatable also triggers senescence and subsequent ripening in the fruits.
Are postharvest losses in Tomatoes quantitative or qualitative?
Postharvest losses in tomatoes can be either quantitative or qualitative. Even though emphasis in crop research nowadays is increasing shifting from quantity to quality of produce, there is still little improvement in the quality of commercially produced tomato varieties, hence resulting in high quality losses.
