Fruit Bagging

A study was performed during 2016 from January to July for safe mango production by applying the minimum use of pesticides. The mango fruits were bagged at marble stage (45 days after fruit set) with various treatments viz: T0: No bagging (control), T1: Brown paper double-layered bag (BPB); T2: White paper single-layered bag (WPB); T3: Perforated polythene bag (PB) and T4: White cloth bag (WCB). In physical parameters, brown and white paper bag recorded the maximum fruit weight (169.10 g and 147.6 g), fruit length (8.57 and 8.33 cm), fruit diameter (5.63 and 5.87 cm) and pulp weight (124.47 g and 105.60 g) respectively, while minimum result was found in the other treatments and control. Meanwhile, in bagging fruits, chemical parameters of total soluble solids, ascorbic acid, percent of citric acid, reducing sugars and β- carotene were increased over control. Brown paper bag changed fruit color. The sensory qualities in fruits of brown and white paper bags were improved over control. Fruit retention was significantly improved by pre-harvest fruit bagging with a brown paper bag (95.90%), white paper bag (95.50%), and control (90.00%) over polythene bag (80.00%). Fruits with brown paper bags showed shelf life up to 18 days with good physical quality and the lowest weight loss against 15 days of control fruits. The sensory attributes were better in fruits of brown, white paper and white cloth bags over control. Bagging at marble stage also reduced the occurrence of spongy tissue and the incidence of mealy bugs. These results indicate that fruit bagging can improve the quality and the shelf life of mango cv. Amrapali through the reduction of disease and insect-pest attack.

Mango is one of the main fruits grown in Chad. However, it is prone to high post-harvest losses due to lack of adequate distribution networks, appropriate harvesting and conservation methods. The objective of this study was to test the effectiveness of coatings based on extracts of Allium sativum (garlic), Zingiber officinale (ginger) and Spirulina platensis (spirulina) on their conservation. Shelf life, weight loss, firmness, pH and total soluble solids content of mangoes were evaluated. The coated mangoes had excellent brillance compared to control mangoes. The coatings based on the extracts of A. sativum, S. platensis and Z. officinale increased respectively the means shelf life of mangoes to 18, 19 and 24 days. Weight losses were 21% for control mangoes while they were 13% for mangoes coated using mixture containing extracts of A. sativum and S. platensis and 11% for mangoes coated with Z. officinale. Coatings based on extracts of Z. officinale and S. platensis had statistically comparable effects on the firmness of mangoes but significantly higher than those of A. sativum extracts and controls after the 10th day. pH values and total soluble solids content (TSSC) values of control mangoes were significantly higher than those of coated mangoes. On day 10 after treatment, chlorophylls were absent from the peel of control mangoes whereas they were still present in the peel of coated mangoes. The mangoes coated with extract of Z. officinale reached a shelf life of 24 days. This shelf life was significantly higher than that of mangoes coated with other types of extracts and control mangoes. The coating with Z. officinale extract slowed considerably the ripening of mangoes. It can be recommended for conservation of mangoes in fresh.

The aim of extending shelf-life and maintaining quality is one of the major issues regarding mango fruit preservation. The quality of mango fruits is greatly affected by postharvest factors, especially temperature and fruit treatment. In this study, the effect of coating and storage temperature on the characteristics of mango fruits was investigated. The mango fruits were immersed in different concentrations (1.5%, 2.0%, and 2.5%) of pectin/nanochitosan dispersion (with ratios of pectin:nanochitosan 50:50), and (0.75%, 1% and 1.25%) of nanochitosan dispersion and stored at 17, 25, and 32 °C for 24 days. Changes in fruit, including weight loss, firmness, color, chemical composition (such as the total soluble solids concentration (TSS)), total sugar, reducing sugar, titratable acidity (TA), and vitamin C were periodically recorded. The results indicated that the pectin/nanochitosan coating significantly prevented reductions in the fruit weight, firmness, TSS, TA, and vitamin C content. Additionally, pectin/nanochitosan at a low temperature (17 °C) had a greater positive effect on fruit shelf-life and weight maintenance than 25 and 32 °C. The coated mango fruits maintained good quality for 24 days at 17 °C, while coated fruits stored at 25 °C and 32 °C, as well as uncoated ones stored at 17 °C, were destroyed after two weeks. At the maximum storage time evaluated, the coating formulations containing pectin and nanochitosan exhibited microbial counts below the storage life limit of 106 CFU/g of fruit. In general, the results showed that the pectin/nanochitosan coating (2%) with a storage temperature of 17 °C is the most effective strategy for improving quality and extending the shelf-life of mango fruits.

Fruit Bagging

Mango (Mangifera indica L.) is famous among all fruits because of its taste, variety and color. However, the quality of mango fruits is mainly deteriorated by insect-pests complex. The study was performed to evaluate bagging effects on insect-pests complex, yield and quality of mango fruits at private mango orchards located in Multan district. A mango cultivar, Anwar Rataul was selected, and the fruits were bagged during 1st week of May (at stone size stage) to 1st week of July 2017 (at maturity stage). The results indicated that the attack of fruit flies and other insect-pests complex were zero in bagged fruits. It was further recorded that the maximum average fruit weight i.e. 203.50 g was noted in those where butter paper bag was wrapped as compared with brown paper bagged fruits having 197.83 g and un-bagged fruits with 159.50 g per fruit. However, brown paper bag resulted in better fruit color development. Similarly, average fruit lengths were greater i.e. 91.33 and 90.18 mm in butter paper and brown paper bagged fruits, respectively as compared to 85.33 mm in un-bagged fruits. Bagged fruits had higher total soluble solids and slightly lower titratable acidity as compared to un-bagged fruits. Further, bagged fruits had no cracks, sunburn, mechanical injury, bird damage, skin blemishes and agrochemical residues. So, it is concluded that fruit bagging on mango cv. Anwar Rataul trees at stone size stage proved to be an effective practice against insect-pests complex and for quality production of fruits for export purposes.

Demand for minimally processed fruits have increased due to their nutritional value and an increasing change in consumption habits. Physicochemical, microbiological, structural and sensory changes were determined in minimally processed mangoes (MPM) with chitosan (CH) edible coatings and lemon and orange essential oils (EOL). The MPM was first dipped in citric acid and a texturizing solution and then dipped in CH and lemon or orange EOL coatings. Weight loss, sensory acceptance, total soluble solids, total acidity, ascorbic acid, color changes, firmness and elasticity, and microbiological changes were quantified for 11 days of refrigerated storage. The CH and lemon EOL coating had more acceptance than the other treatments. No differences were found (p>0.05) for weight loss, total acidity, ascorbic acid, firmness or elasticity. There was a high amount of total phenols due to the EOL composition, as well as a high antioxidant capacity in the early days of storage. This characteristic decreased in the final days of the study. There was a decrease in the microbial charge for the lemon EOL treatment, as compared to the other samples. The CH and lemon EOL coating helped to maintain the shelf-life of the MPM for 11 days of storage without affecting the sensory acceptance. The CH and Orange EOL coating did not have an effect on the MPM physicochemical attributes; however, the sensory acceptance was negatively affected with off-flavors conferred to the MPM.

Objective: To identify the morphometric and biochemical variation in mango fruits var. Ataulfo (Mangifera indica L.) in two contrasting environments with and without conventional management. Design/methodology/approximation: Morphological and biochemical variables were studied in mango fruits var. Ataulfo in two environments, one of them (La Norteña) with Leptosol soil and Aw climate with conventional agrochemical-based management and the other (Santa Cecilia) on Acrisol soil and Am climate with agroecological management. There were 30 fruits used, all from five trees (n=150) per study garden in a state of commercial maturity. Each fruit was considered as an experimental unit, and morphological and biochemical variables were evaluated for each fruit. Results: Increase in fruit weight, higher pH and increase in total soluble solids, but decrease in pulp weight on site with conventional handling. Increase in pulp content and firmness in fruits from the site without handling. Study Limitations/implications: Changes in the amount and distribution of rainfall in both environments each year. Findings / conclusions: Morphological and biochemical modifications are presented. Greater size and weight, pH and TSS content in the conventional production system, but increased pulp and greater firmness, as well as higher citric acid content in the agroecological system. The results suggest differential effects in mango fruits according to the management and environment where they develop.

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.

Quality And Shelf Life

Banana is a climacteric fruit with a short shelf life. As a result, huge losses are incurred during handling in the value chain. The need to develop means of extending the shelf life and concomitantly maintaining the quality of the fruit after harvest has become very important. This study was conducted to determine the effects of two different edible waxing materials (beeswax and cassava starch) used as coatings on the quality and shelf life of Mysore banana. The study was conducted in the laboratory at the Department of Horticulture, Kwame Nkrumah University of Science and Technology–Kumasi. The experiment was laid out in a simple completely randomized design (CRD) and replicated three (3) times with three treatments (beeswax, cassava starch and a control). Parameters studied were: fruit weight loss, firmness, peel colour, pulp-to-peel ratio, moisture content (MC), dry matter content (DMC), total titratable acidity (TTA), total soluble solids (TSS), pH, green life and shelf life. The results showed beeswax and cassava starch had no significant effect (P>0.01) on peel colour, fruit firmness, TTA, TSS, DMC, MC and green life. Beeswax, however, kept weight loss minimal, and reduced TSS and the pulp-to-peel ratio of the fruits during storage. We conclude that beeswax was the best treatment in terms of waxing Mysore banana fruits to maintained its quality and ultimately prolonged its shelf life by about four (4) days more than the control.
