Handling Practices

Tomato production has increased in recent years due to the economic and nutritional importance of the crop. This increase is made possible by the numerous research advances made along the entire value chain. However, scientific research has been focussed mainly on production whilst neglecting postharvest issues. Tomato producers have therefore enjoyed good harvests in recent times, though the good harvests of those from developing countries do not translate into profit as most are lost after harvest. From this study, it was revealed that the postharvest quality and shelf life of the fruit in part will depend on some postharvest handling practices and treatments carried out after harvest. 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. Using appropriate postharvest treatments like refrigeration, heat treatment, modified atmosphere packaging (MAP), and 1-methylcyclopropene (1-MCP) and calcium chloride (CaCl2) application was also vital. It was concluded by this study that the quality of the harvested fruit can be maintained and shelf life extended by using appropriate postharvest handling practices and treatment methods. Failure to adhere to these practices will result in a high amount of loss.

Red raspberries (Rubus idaeus L.) are highly appreciated by consumers. However, their postharvest shelf life scarcely exceeds 5 d under the refrigeration temperatures usually applied during commercialization, due to their high susceptibility to dehydration, softening and rot incidence. Thus, the objective of this study was to investigate the ability of UV-C radiation (UV1: 2 kJ m−2 and UV2: 4 kJ m−2), passive modified atmosphere packaging (MAP) with transmission rates (TR) for O2 and CO2 of 1805 mL d−1 and 1570 mL d−1 (MAP1), and 902 mL d−1 and 785 mL d−1 (MAP2), respectively, and the combination of both technologies to prolong raspberries’ shelf life at 6 °C. Their influence on respiration, physicochemical parameters, and microbiological and nutritional quality was assessed during 12 d of storage. The combination of 4 kJ m−2 UV-C radiation and a packaging film with O2 and CO2 transmission rates of 902 mL d−1 and 785 mL d−1, respectively, produced a synergistic effect against rot development, delaying senescence of the fruit. The UV2MAP2 and MAP2 samples only showed 1.66% rot incidence after 8 d of storage. The UV2MAP2 samples also had higher bioactive content (1.76 g kg−1 of gallic acid equivalents (GAE), 1.08 g kg−1 of catechin equivalents (CE) and 0.32 g kg−1 of cyanidin 3-O-glucoside equivalents (CGE)) than the control samples at the end of their shelf life. Moreover, the mass loss was minimal (0.56%), and fruit color and firmness were maintained during shelf life. However, the rest of the batches were not suitable for commercialization after 4 d due to excessive mold development.

Tomato production can serve as a source of income for most rural and periurban producers in most developing countries of the world. However, postharvest losses make its production unprofitable in these parts of the world. Postharvest losses in tomatoes can be as high as 42% globally. 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. From the study it was discovered that the postharvest quality status of tomatoes partly depended on some preharvest practices carried out during production. Some of these factors are fertiliser application, pruning, maturity stage, cultivar selection, and irrigation. Using best postharvest handling practices or factors such as temperature, relative humidity, gases in storage, postharvest calcium chloride application, and physical handling procedures to maintain the quality after harvest was also critical. It was concluded by this study that understanding and managing both preharvest and postharvest factors properly will reduce the postharvest quality losses in tomatoes.

The present study evaluated the effect of NPK fertilizer (17:17:17) rates (0, 100, 200, 300 and 400 kg ha-1) on the postharvest quality of field and greenhouse grown pepino melons (Solanum muricatum Ait.) stored at room temperature (15-22°C) and at low temperature (7°C). The study was carried out in randomized complete block design with fruits from the field and greenhouse, five NPK fertilizer rates as treatments and the two storage temperatures replicated three times. Data were collected on percentage fruit weight loss (PWL), total soluble solids (TSS), firmness and shelf life. Results indicated that greenhouse and field grown fruits from the control and plants supplied with 100 kg NPK ha-1 had low PWL at both storage temperatures. Field grown fruits from the control stored at room temperature had the highest TSS and were firmer after 28 days of storage. Field grown fruits not supplied with fertilizer and stored at low temperature had a shelf life of 27 and 26 days in trial one and two respectively. Application of 100 kg NPK ha-1 and storage of pepino melon fruits at low temperature can be used to enhance quality and shelf life.

The study was carried out to minimize the postharvest loses and extend shelf life of mango fruitby maintaining physico-chemical properties. The variety selected for the study was “Amrapali”. Freshly harvested mango was treated with different concentrations (20% and 40%) of neem leaf and banana pulp extract alone or in combination. Untreated mango was considered as control. All treated and untreated mango was kept into paper cartons at room condition. The treated fruits showed significant differences in case of total soluble solids content, titratable acidity, vitamin C, disease incidence, disease severity and shelf life in comparison to control fruits. Among the treatments, T2 (neem leaf extract at 20%) and T5 (neem leaf extract 40% + banana pulp extract 40%) treatments showed longer shelf life (9.92 and 10.25 days, respectively), slower changes in color (score 2.77 and 2.93, respectively) and firmness (score 2.67 and 2.77, respectively); less disease severity (score 2.93 and 3.57, respectively), disease incidence (46.67% and 60.00%) and lower loss in weight (38.04% and 35.17%, respectively) at 9 DAT (Days after treatment). On the other hand, total soluble solid was highest in T3 (neem leaf extract 40%) treated fruitswith18.73% more Brix at 13 DAT in comparison to control and other treatments. The effectiveness of the treatment T5 (neem leaf extract 40% + banana pulp extract 40%) was meaningful which could be recommended for maintenance of postharvest quality of mango stored in ambient conditions.

Postharvest Treatment

1-Methylcyclopropene (1-MCP) is applied as an inhibitor of ethylene action, which is widely used in postharvest technology to prolong the shelf life of many fruits. The aim of the study was to assess the possibility to apply 1-MCP treatment to maintain the quality of ‘Idared’ apples for long-distance transportation. The studied apples were assessed in three groups: (I) 1-MCP postharvest treatment; (II) 1-MCP postharvest treatment with Modified Atmosphere Packaging (MAP) selected gas permeability bags; and (III) control groups (with neither 1-MCP treatment, nor dedicated packaging). Apples were subjected to storage in the Ultra Low Oxygen (ULO) chamber that was applied for 0 weeks, 10 weeks and 20 weeks (three periods of storage); simulated long-distance transport (6 weeks); and simulated distribution, which was applied for 0 days, 5 days, 10 days, and 15 days (4 periods of distribution). The obtained 36 groups (three postharvest treatments per three periods of storage per four periods of distribution) were analyzed to assess firmness, total soluble solids (TSS) and titratable acidity (TA). There were differences between firmness values for control groups and those with 1-MCP applied, which were characterized by higher values of firmness (p < 0.05). Groups with 1-MCP and MAP applied combined were characterized by higher values of TSS than control groups (p < 0.05). The majority of groups with 1-MCP applied alone were characterized by higher values of TA than control groups (p < 0.05), but values for samples attributed to 1-MCP and MAP combined were not higher than for 1-MCP alone. It may be concluded that 1-MCP applied postharvest contributed to higher results of firmness and TA of ‘Idared’ apples after long-distance transportation, but combining 1-MCP with MAP did not contribute to further differences for TA. However, for TSS the observed influence was inconclusive. It may be stated that 1-MCP is a beneficial treatment for ‘Idared’ apples for long-distance transportation as it prolongs their shelf life and improves firmness.
