Introduction: Bruising is a type of mechanical damage that challenges fresh horticulture production efforts, which occurs mainly due to excessive compression and impact forces during postharvest operations resulting in quality deterioration of fresh produce and reduction in economic value. Objective: This study aims to assess the bruise susceptibility of imported pears and determine its effect on pear quality attributes. Materials and Methods: Each Pyrus communis, variety ‘D'Anjou’ imported pears was impacted by a known mass steel ball at three different drop heights (20, 40, and 60 cm). Bruised fruit was stored at 22°C with 45±5% RH and 10°C with 85±5% RH for 48 hours storage period. Pears were also subjected to different quality analyses like color, firmness, weight loss, and total soluble solids (TSS). The analysis was conducted by performing two factorial balanced analyses of variance (ANOVA). Results: Bruise area, bruise volume, and bruise susceptibility were the highest at higher drop impact (60 cm) on pears stored at 22°C and the lowest were at lower drop impact (20 cm) on pears stored at 10°C. Furthermore, there was a statistically significant impact of drop height and temperature on bruising susceptibility. Besides, statistics showed a significant impact of the studied factors (temperature and drop height) on quality parameters of pears such as lightness (L*), redness-greenness (a*), weight loss, and firmness after 48 hours of storage Conclusion: Mechanical damages like bruising can be affected by many factors like storage temperature and impact level force. Finally, it was concluded that mechanical damages like bruising can be affected by many factors like storage temperature and impact force. Overall, this study can consider as a guideline for workers during postharvest operations and handling.

AbstractFresh fruits like bananas are very susceptible to mechanical damage during postharvest handling which can result in a substantial decline in quality. The study aims to evaluate the effect of bruise damage and storage temperatures on the quality of banana fruits after 48 h storage. Each ‘Grand Naine’ banana fruit was impacted once by using a drop impact test using three different heights (10, 30, and 50 cm) and storage temperatures (13 and 22 °C) after 48 h of storage. Different quality analyses were measured like bruise measurements (impact energy, bruise area, bruise volume, and bruise susceptibility), weight loss, total soluble solids (TSS), color (L*, a*, b*, hue°, chroma, yellowness index, yellowness value) headspace gases (respiration and ethylene production rate). The results showed that bruise measurements (bruise area, bruise volume, and bruise susceptibility) were highly affected by drop height. The quality parameters like weight, color, total soluble solids and headspace gases were affected by drop height and storage condition. Weight loss, total soluble solids, respiration rate, and ethylene production rate increased as drop height and storage temperature rise. Storage at ambient conditions (22 °C) accelerated bruising occurrence in banana fruits. Fewer changes were observed after 48 h of storage. The least value of yellowness index was observed on the non-bruised banana fruits (84.03) under 13 °C storage conditions. The findings of the study can provide baseline data to understand the mechanical damage mechanism on fruit quality, hoping to create awareness and educate farming communities and consumers. Storage temperature management is another approach that needs to be followed to reduce the occurrence of mechanical damage in fresh produce.

ABSTRACT‘Regina’ sweet cherry fruit (Prunus avium L.) harvested from trees grown on vigorous and semi-dwarfing rootstocks was stored in normal atmosphere (NA) at 8°C and 2°C, and in a controlled atmosphere (CA) 3% O2 + 5% CO2at 2°C for two weeks. At harvest time, the fruits differed in the measured quality parameters (firmness, soluble solids content - SSC, titratable acidity - TA) depending on the rootstock. The storage conditions and the rootstocks significantly influenced the fruit quality parameters after storage. Generally, reduced fruit firmness and TA, and higher SSC and SSC/TA ratio were observed at the end of the storage period. Among the rootstocks, the lowest soluble solids content was found in the fruit from trees on the vigorous F12/1 rootstock. The lower storage temperature decreased the SSC independently of the storage atmosphere composition. Firmer fruit was found in CA 2°C compared with the other two treatments. The greatest loss of weight was found after fruit storage in NA 8°C. The extent of fruit decay depended on the season, storage conditions and the rootstock. Storage in NA 8°C of the fruit grown on F12/1 rootstock resulted in the highest percentage of fungal decay. The best retention of the green colour of the peduncle was noted in CA 2°C. The findings on how the rootstocks affect sweet cherry fruit properties can be useful for sweet cherry breeding programmes, as well as for sweet cherry crop production and storage technologies.

This study examined three main possible effects (impact, storage temperature, and duration) that cause and extend the level of bruising and other quality attributes contributing to the deterioration of tomatoes. The impact threshold level required to cause bruising was conducted by subjecting tomato samples to a steel ball with a known mass from different drop heights (20, 40, and 60 cm). The samples were then divided and stored at 10 and 22 °C for 10 days for the further analysis of bruise area and any physiological, chemical, and nutritional changes at two day intervals. Six prediction models were constructed for the bruised area and other quality attribute changes of the tomato. Storage time, bruise area, weight loss, redness, total color change, color index, total soluble solids, and pigments content (lycopene and carotenoids) showed a significant (p < 0.05) increase with the increase of drop height (impact level) and storage temperature. After 10 days of storage, high drop impact and storage at 22 °C generated a higher reduction in firmness, lightness, yellowness, and hue° (color purity). Additionally, regression model findings showed the significant effect of storage duration, storage temperature, and drop height on the measured variables (bruise area, weight loss, firmness, redness, total soluble solids, and lycopene) at a 5% probability level with a determination coefficient (R2) ranging from 0.76 to 0.95. Bruising and other quality attributes could be reduced by reducing the temperature during storage. This study can help tomato transporters, handlers, and suppliers to understand the mechanism of bruising occurrence and how to reduce it.

Postharvest response of wild lowbush blueberry (Vaccinium angustifolium Ait. and V. myrtilloides Michx.) to mechanical damage and storage temperature was studied during 2 years. Fruit weight loss and the incidence of shriveled or split berries were major components that contributed to the loss of marketable yield resulting from mechanical damage and storage temperature. Decay of berries resulted in only 1% to 2% of the total marketable fruit loss. In general, the major quality attributes (firmness, microbial growth, hue, bloom, split, and unblemished berries) deteriorated with increasing damage levels and increasing storage temperature without significant interaction. Temperature had consistent effects in both years on moisture content, soluble solids concentration, titratable acids, weight loss, shriveled and decayed berries, Hunter L values, and anthocyanin leakage, while damage level had inconsistent or no significant effect.

Improper postharvest handling, including delaying cooling, is a big concern for maintaining the freshness of fruit and vegetables in the postharvest supply chain. The objective of this study was to investigate the influence of short delays in cooling on some important quality parameters such as physiological weight loss, firmness, total soluble solids (TSS), and color (L*, h°, and C*) values of bell peppers stored in a controlled chamber. Bell peppers treated with three different treatments showed a gradual physiological weight loss of 1.46%, 3.18%, and 3.14% after a storage period of 15 days with: immediate storage (IS) after harvest in a controlled chamber, delaying storage (DS), leaving bell pepper without cover for one day, and under cover (DSC) separately in a greenhouse and then storing them in the controlled chamber, respectively. Over the storage period, slower firmness reduction (19.88%) of the IS treated bell peppers was observed compared to other bell pepper samples with delayed cooling. Bell peppers that underwent IS treatment showed lower changes in TSS (°Bx) values (6.89 to 7.24) compared to other treatments during the storage period. Fewer changes in color (L*, h°, and C*) values were found with IS treated bell peppers. Overall changes in the assessed quality parameters of bell pepper samples were slower with IS treatment than delayed cooling treatments throughout the storage period. This study provides significant information on the handling of harvested bell pepper in a favorable environment before transportation to processing and storage centers.

The influence of short anoxia treatment on physical, chemical and sensory attributes of mature green and pink red tomatoes during storage was investigated. Matured green and pink red fruits were kept for 24 hrs under humidified pure N2, while the control was not treated. Subsequently, the fruits were stored at 12?C and 20?C for 14 days. Quality parameters including weight loss, firmness, total soluble solids, colour, sensory and decay were analyzed. Generally, weight loss increased after 14 days of storage and depending on anoxia treatment, maturity and storage temperature. Tomato fruit treated with anoxia and kept at 12?C showed a minimal deterioration of the quality attributes and could be stored for longer periods compared to those stored at 20?C. Results for TSS were higher in tomato fruit treated with anoxia. However, pink red fruit stored at 20?C showed lower TSS than untreated fruit. Untreated and anoxia-pretreated mature green tomatoes showed higher sourness and off-flavour scores than those stored at 20?C. However, mature green and pink red tomatoes kept at 20?C showed higher acceptance (%) than those stored at 12?C. Therefore, combined effect of anoxia and low temperature could have delayed the ripening of the tomatoes.

Abstract Raspberry and strawberry fruits were stored at 0 °C and relative humidity (RH) of 95% for eight days. The fruits were treated with calcium chloride and their quality parameters and weight loss monitored and compared with those of untreated ones. A higher weight loss was observed for the untreated raspberries (16%) than for the fruits treated with 2% calcium chloride (5.3%). Similarly, untreated strawberry fruits lost more weight (8.5%) than those treated with 2% calcium chloride – only 4.1%. The application of calcium chloride did not significantly influence the total acid content of the fruits. After 8 days storage the total soluble solids (TSS) had decreased to 10.22 ± 0.06, 9.60 ± 0.05 and 9.65 ± 0.12 in the raspberry fruits treated with 0%, 1% and 2% calcium chloride, respectively, and to 7.00 ± 0.17, 6.57 ± 0.08 and 6.35 ± 0.04 in the strawberry fruits treated with 0%, 1% and 2% calcium chloride, respectively. After storage, the ascorbic acid contents were significantly (p ≤ 0.05) higher in samples of raspberry and strawberry fruits subjected to 2% calcium chloride dips. The CaCl2 treatments had a significant effect on retaining the ascorbic acid contents in these fruits. The treatment of raspberry and strawberry fruits with calcium chloride had a positive effect (p< 0.05) on the retention of the total phenolic contents (TPC) during the storage period. 66% and 74% of the antioxidant potentials were retained in the untreated samples of raspberries and strawberries, as against 78% and 89% in the 2% calcium chloride treated samples of these fruits.

Pitaya is a non-climacteric fruit that has white or red flesh with numerous small, black seeds. It has a high moisture content; however, water loss during handling and storage negatively affects the fresh weight, firmness and appearance of the fruit, decreasing market value. Application of compatible postharvest coatings has been shown to benefit postharvest quality of many crops. The objective of this study was to evaluate the effect of two commercial coatings on weight loss and quality of pitaya during storage. Pitaya fruit were commercially harvested and sorted for uniformity of size and freedom from defects. Fruit were briefly immersed in either a vegetable oil-based coating (VOC; Sta-Fresh® 2981) or a carnauba-based coating (CC; Endura-Fresh™ 6100) according to manufacturer’s recommendations. Fruit immersed in tap water served as a control. Fruit were fan-dried at room temperature for 20 min, then stored at 7 °C with 85% relative humidity (RH) and evaluated for selected physical quality parameters each 5 days during 20 days. After each evaluation, fruit were peeled and frozen for later analysis of soluble solids content (SSC), total titratable acidity (TTA); on day 15 fresh samples were evaluated by an untrained consumer sensory panel. CC prevented exocarp shriveling for 15 days of storage, compared to uncoated pitaya (16.3% area affected); shriveling in VOC was intermediate and not significantly different from the other treatments. Mesocarp firmness remained constant throughout 15 days of storage regardless of treatment. Fruit exocarp h* angle increased slightly by day 20, becoming slightly less red, and there were no negative treatment effects for the other quality factors measured: SSC (11.33%), TTA (0.25%), weight loss (5.5%) or sensory evaluations (appearance, flavor, texture, firmness, and juiciness). After 20 days storage, appearance for fruit from all treatments was rated unacceptable due to development of anthracnose lesions. It was concluded that both CC and VOC maintained quality of pitaya for 15 days at 7 °C and 85% RH by delaying exocarp shriveling.
