This chapter identifies the preharvest factors that can affect the quality of harvested fruit and ways in which to produce fruit with less predisposition to postharvest disorders. The effects of preharvest factors on postharvest quality are often overlooked and underestimated. Nutrient retention is optimized When ethylene is applied to climacteric fruits, at a concentration as low as 0.1-1.0 ml/l, for 1 … Mechanical harvesting, for example, may incur more bruises and cracks in fruits and vegetables than hand harvesting. Changes are noticed more in climacteric fruits and vegetables than non-climacteric. Growing conditions, time of harvest and harvesting methods are of great importance for the postharvest quality attributes of fresh produce. 1.2 Harvesting Methods The crop type and expected harvest volume will determine the harvesting method that is to be used. Factors affecting Post-Harvest Loss. There are many factors quality is desirable for most processing methods, the composition of fruit in relation to flavors, texture, color and nutritional value is … harvesting, handling, grading of fruits, vegetables, cut flowers, plantation crops, medicinal and aromatic plants. Harvest methods. Fruit and vegetable gloss are related to the ability of a surface to re-ﬂect light and freshly harvested products are often more glossy (Mitcham et al., 1996). Post-harvest activities include harvesting, handling, storage, processing, packaging, transportation and marketing.. Losses of horticultural produce are a major problem in the post-harvest chain.They can be caused by a wide … The determination of these specific changes can be done in a subjective manner by the person who is harvesting. Genetic factors also have a significant effect. HARVESTING. Differences among plant parts and in the nature of their surface coatings (e.g. Hand harvesting usually provides a better quality product than mechanical harvesting. Harvesting is the act of removing a crop from where it was growing and moving it to a more secure location for processing, consumption, or storage. Box HP, Ho, Ghana A farmer growing fruits for his Internal factors Type of Commodity. Introduction. HARVESTING. In large number of fruits, before the ripening is ultimately achieved there is accumulation of ABA (Fig. In addition, be aware that factors such as gender, customs, and role/position within the growing fields can affect the dynamics and comfort level of the group. 4. Small fruit size is one of the limiting factors in marketing the fruits of many species. Time of day to harvest. CITRUS INDUSTRY • December 2011 7 eye-appeal at maturity. Pre-harvest factors affecting quality, factors responsible for deterioration of horticultural produce, physiological and bio-chemical changes, hardening and delaying ripening process. This paper deals primarily with fertilizer and cultural management practices, and on certain environmental factors that affect the nutritional quality of field crops and of fruits and vegetables. 25-2). • Know about different step in handling of produce after harvest. This method works well for some commodities and in some locations, but not for all crops or for all growers. Obtaining the optimum postharvest quality of vegetables actually begins very early in the farm planning process. Mechanical harvesting generally causes more stress to the plant tissue and may result in more damage than hand harvesting. It usually works best for fruits or vegetables that are purchased in fairly large quantities for home processing. Factors influencing bruise damage of fresh fruits 4.1. A very common cause of poor product quality at harvest and rapid deterioration thereafter is harvesting immature fruits. handling system of the distribution chain of perishables (from harvesting, through handling, packing, storage and transportation to final delivery of the fresh produce to the consumer). 117 PLASTICS IN FOOD PACKAGING PACKAGING ASPECTS OF FRUITS AND VEGETABLES Chapter 6 PACKAGING ASPECTS OF FRUITS AND VEGETABLES PRODUCT CHARACTERISTICS Fruits and vegetables are living organisms even after harvesting; they can remain fresh only as long as normal metabolism continues. Perhaps this phytohormone regulates fruit ripening. cuticle thickness, stomata, lenticels) influence their rate of diffusion characteristic and consequently their respiration rates. Fruit size depends on the cul-tivar considered, cultural practices and environmental conditions . CHAPTER 2. Mechanical Injury Mechanical damage of fruits and vegetables are caused by careless handling during harvesting, packing, transportation, storage etc. Few important factors of the fruits and vegetable maturity can be mentioned as the following: Colour of the fruits: The skin of the fruit will change when the fruit reaches the stage of maturity or it also gets ripened. Similarly banana fruits sprayed with GA do not undergo yellowing even though other processes occur normally. 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. Certain crops are harvested by hand, while others are harvested either manually or mechanically. In both fruits and vegetables, many more additional changes take place after harvesting. Earlier research that has investigated the nutritional status of crops grown with either chemical fertilizers or organic fertilizers is discussed. Fruits harvested immature or over mature usually do not keep long. Other factors affecting the impact of the ripening stage on disease susceptibility involve the enhanced virulence of the pathogen, weakened host resistance and protection. One of the primary factors enhancing the susceptibility of the fruits to infection is the enhanced susceptibility of the plant cell walls to the activity of enzymes produced and secreted by the pathogens. Fruits and vegetables for the fresh market are generally harvested by hand, with the exception of roots and tubers, while many commodities destined for processing are mechanically harvested. As such, it should be no surprise that agricultural industries and related activities can account for a considerable proportion of their output. However, many of the decisions that we make during crop production can greatly influence the postharvest quality of crops. In general, post-harvest losses of fruits and vegetables is influence by many factors. The cost of fruit harvesting can range between 20% and 40% of the total on-farm variable production costs and is largely contributed by manual labour (He et al., 2017). In lowland tropical areas, due to high respiration rates at warm tem-peratures, fruit mature quickly and do not have sufficient time to accumulate high TSS, and acidity declines rapidly Most crops (with the exception of … Stage of harvesting: Fruits must be harvested at right stage of maturity. Vegetables: The primary factors of post-harvest loss of fruits and vegetables are mainly cause by mechanical physiological pathological or environmental factors . Harvesting crops at peak maturity and quality (see Appendix 1: Handling Information for Fruits and Vegetables, and Appendix 2: Suggested Displays and Storage Groups for Selected Vegetables) 2. 7.2 Marketing of fruits and vegetables 27 8 Maturity standards of fruits and vegetables 29-35 8.1 Types of maturity 30 8.2 Determination of harvest maturity 30 8.3 Effects of maturity on physico-chemical changes and ripening 31 8.4 Maturity symptoms of selected fruits and vegetables 32 8.5 Methods of harvesting 34 Factors affecting citrus production and quality. Post-harvest Losses of vegetables and fruit occur at all points in the value chain from production in the field to the food being placed on a plate for consumption. 1. • Know about the maturity indices of fruits and vegetables. Some changes are desirable from consumer point of view, but most of them are undesirable. Fruits and vegetables vary greatly in their respiration rate (Table. Harvest factors 4.1.1. Your customers perform a large amount of the marketing function and do the harvesting. Final plum fruit size is highly affected by water availability during development , and early har-vest may lead to fruit with decreased size. PDF | On Aug 1, 1997, Carlos H. Crisostol and others published Orchard Development of sweetness, color, and flavor are best examples of desirable changes. mango harvester in Lucknow (CISH). Gloss is affected by moisture content, In apples after a week of harvesting ABA content increases many times. 1). Review Article Preharvest and Postharvest Factors Affecting the Quality and Shelf Life of Harvested Tomatoes: A Mini Review IsaacKojoArah, 1 HarrisonAmaglo, 1 ErnestKodzoKumah, 2 andHayfordOfori 1 Department of Agricultural Engineering, Ho Polytechnic, P.O. Light exposure Harvesting, Handling and Storage of Horticultural Crops OBJECTIVES After studying this chapter, students will be able to: • Know about importance of safe harvesting, handling and storage of fruits and vegetables. All fruits produce small amounts of ethylene during development and when damaged or stressed. Factors affecting post-harvest losses vary widely from place to place and are more and more difficult. Factors, affecting, Fruits, Vegetables and Quality Introduction Not all varieties of fruits and vegetables are satisfactory for processing. Some harvesting gadgets have been developed, e.g. BASIC HARVEST AND POST-HARVEST HANDLING CONSIDERATIONS FOR FRESH During ripening, climacteric fruits produce larger amounts of ethylene than non climacteric fruits.
