Post-harvest assessment of fruit quality and shelf life of two elite tomato varieties cultivated in Bangladesh

Abstract

Background: Tomatoes are now one of the most popular nutrient-dense vegetables in terms of acreage, production, yield, commercial use, and consumption that add to the Bangladesh economy and ultimately reduce poverty. With this view, a lab investigation was carried out to analyze the effects of tomato (Sofol and Roma VF) verities on different post-harvest managements to extend shelf life as well as reduce post-harvest losses.Results: This study confirmed that the fruit quality attributes (color, firmness, weight loss, chilling injury, total soluble solids, pH, disease incidence, disease severity, and dry matter content) were increased whereas moisture content, vitamin C, and titratable acidity decreased with the increases in storage duration. The high quality attributes such as color, firmness, weight loss, chilling injury, total soluble solids, pH, disease incidence, disease severity, and dry matter content increased, whereas moisture content, vitamin C and titratable acidity decrease of tomato were observed in Roma VF while Sofol variety had high weight loss, moisture content, titratable acidity, and vitamin C. Moreover, the highest shelf life (17 days) was recorded in Sofol than Roma VF (15 days). On the 16th day of storage, maximum disease severity (41%) and disease incidence (71%) were observed at an earthen cooling pot, whereas a significant reduction in disease severity (1%) and disease incidence (8%) were recorded in tomatoes stored at 10 o C temperature. Weight loss was the lowest (4%) in Sofol when kept at unperforated low-density polyethylene (LDPL) plastic bag as compared to Roma VF treatment (11%). Considering the physiological process, held at the low temperature (10°C and 15°C) and increased shelf life as well as reduced the diseases of tomatoes. Conclusions: The investigator concluded that the findings of this study will be helpful with specific regard to long and medium-term storage, quality control, transportation, and advertising, and will also be beneficial to tomato growers of Bangladesh.

Effect of Harvesting Stages and Calcium Chloride Application on Postharvest Quality of Tomato Fruits

“…Data showed that the shelf life of tomato fruits was proportionate with the doses of CaCl 2, and it was 3.90%, 5.92%, and 9.12% higher at 1%, 1.5%, and 2% concentration of CaCl 2, respectively, relative to that in control samples. Shelf life of MT-3 tomato fruit is influenced by various pre-and post-harvest factors and calculating the number of days required to attain the full ripening stage when the fruit still maintains the acceptable marketing and eating qualities [66]. Marketing and eating quality were visually observed by the different physiological and physicochemical parameters.…”

“…An unsprayed fruit was used as a positive control. The percentage of disease evidence and severity was carried out by a weight loss method using the following relationship (eq ), where DS is the percentage of disease severity, W o is the original weight of the fresh fruit, and W l is the average weight loss in moisture content after 10 d.…”

Edible coating as postharvest management strategy for shelf‐life extension of fresh tomato (Solanum lycopersicumL.): An overview

“…During storage of tomato, there is a loss of firmness due to the enhanced activity of the cell wall degrading enzymes, such as polygalacturonase and pectin methyl esterase, leading to reduction in cell‐to‐cell adhesion, resulting in loss of cell wall strength (Dijik et al., 2006; Kabir et al., 2020). The activity of enzymes generally depends on respiration rate and ethylene concentration (Sinha et al., 2019). Whereas loss of water from the tomato occurs by reduction in turgor pressure due to transpiration from the stem scars (Fitch et al., 2020).…”
