Hydrothermic Treatment Effects on Some Ripening Changes on Mango Fruits (Mangifera indica L) Crillo de Bocado' during Storage: I. Physical Parameters

Mango fruits `Criollo de Bocado' harvested at the mature-green stage were treated with a hydrothermic treatment of 55 °C for 3 min and stored for 20 days to temperatures of 10 ± 2, 15 ± 2, and 28 ± 2 °C. A randomized design 2 × 3 × 4 with three replications was used. Physical parameters such as color (L*, a*, b*), firmnness, and fresh weight loss were studied. Results reported that mango fruits stored at 10.2 and 15.2 °C showed the highest firmness values. Skin color changed very fast during the first storage days, while pulp color required more time to achieve mature ripe color. Fresh weight loss tended to increase with storage time and with high storage temperature. The lowest storage temperture retarded softening in mango fruits and firmnness reached the highest values.

ABSTRACT Cavendish banana one of the horticultural products that are prone to physiological setbacks and very vulnerable to physical damages after harvest. Various concentrations of tabah bamboo liquid smoke with different soaking times can use as natural preservatives. The bananas used in this study were Cavendish bananas from Buleleng, every bunch consists of at least ten banana with a length of 18.59 cm and a weight of 125 ± 5 g. This study aims to find the best treatment combination of the treatmentoof liquid smoke concentration and soaking time to maintain freshness and shelf life of Cavendish bananas during storage. The experimental design used in this study was a Completely Randomized Design (CRD) with two factors, the first factor was the concentration of tabah bamboo liquid smoke, and the second factor was the soaking time. The first factor consists of four levels of concentration namely 1%, 3%, 5%, and 7%. The second factor consists of three levels of soaking time, namely 10 minutes, 20 minutes and 30 minutes with storage temperature using room temperature (28 ± 2oC). The parameters observed in this study are: repiration rate, weight loss, hardness, level of damages, TPT and organoleptics. The best interaction results are shown in the treatment of 7% concentration of tabah bamboo liquid smoke with 10 minutes of soaking with an average value of respiration rate parameters of 51.18 ml CO2 / kg.hour, an average value of weight loss with a value of 17.61%, an average value of hardness of 3.82 kg, the average value of TPT was 15.65% Brix, the value of the level of damage was 2.40, the average organoleptic value of taste was 4.67, aroma was 4.54 and color was 3.87. The conclus of this study indicates that the combination of A4B1 (7% tabah bamboo liquid smoke concentration with soaking for 10 minutes) is the best combination to keep freshness and the quality of green bananas until the storage period of the 15th day.

Completely Randomized Design

This study aimed to evaluate respiratory activity, color changes and fresh weight variation of ‘Carola’ (red), ‘Avalanche’ (white) and ‘Avalanche Chá’ (tea) roses for seven days after harvest. Respiratory activity, coloration of petals and fresh weight loss were evaluated. Treatments were composed of three rose cultivars and seven days of evaluation, in a 3 x 7 factorial and a completely randomized design with four replicates of two flowers per plot. To determine the respiratory activity, in addition to the four replicates, an “experimental control” was used as a fifth replicate without roses. ‘Avalanche’ and ‘Avalanche Chá’ roses with petals of similar luminosity showed no browning during days after harvest, but are distinct in terms of chromaticity. ‘Carola’ rose has less shiny petals. On harvest day, the respiratory activity is elevated and reduces later until the fourth day, in which there is elevation of this parameter again coinciding with high fresh weight loss. During days after harvest, small changes in the color of petals were observed; however, the main changes were observed in respiratory activity and fresh weight loss.

The effects of retail-display packaging on strawberry fruit quality were studied using freshly harvested `Cardinal' strawberries. Fruit free from blemishes and disease were placed into plastic vented boxes, covered with vented plastic lids or plastic wrap, and placed at 1 and 5C overnight One-half of the treatments were removed from coolers, held at 25C for eight hours, returned to the coolers and evaluated over a 15-day storage period. The plastic overwrap greatly decreased weight loss during 15 days of storage; carbon dioxide reached 0.8 and 2% per mg fresh weight at 1 and 5C, respectively. Type of cover did not affect overall appearance or disease ratings. Exposure of fruit to 25C for eight hours led to no loss of overall quality. Storage of fruit at 50C led to greater disease incidence and loss of quality. The respiration rate of fruit warmed at 25C reached equilibrium after six hours, regardless of initial storage temperature. Fruit in vented dome-lid boxes had more weight loss than plastic-wrapped boxes at both temperatures.

Marketable Fruit

Studies were conducted over three seasons to determine the relationship of temperature and humidity on the storage life of fresh cranberry (Vaccinium macrocarpon Aiton) fruit. Each year, cranberries harvested from four commercial bogs were stored at temperatures ranging from 0 to 10 °C in combination with relative humidities (RH) ranging from 75% to 98%. Fruit were stored under these conditions for up to 6 months and were evaluated monthly for marketability, decay, physiological breakdown, weight loss, and firmness immediately after removal and after an additional week at 20 °C. The percentage of marketable fruit declined substantially over time in all storage conditions with 41% to 57% becoming unmarketable after 2 months as a result of both decay and physiological breakdown. Relative humidity had a greater effect on fruit storage life than temperature and after 5 months, the amount of marketable fruit stored in high (98%) and medium (88%) RH was 71% and 31% less than that stored in low (75% to 82%) RH. Rates of fresh weight loss increased as RH in storage decreased and was 0.41%, 0.81%, and 0.86% per month in fruit stored in high, medium, and low RH, respectively. Fruit firmness was not significantly affected by RH. The effects of storage temperatures ranging from 0 to 7 °C on marketable fruit after 2 to 5 months of storage were not significant. Only fruit stored at 10 °C consistently had fewer marketable fruit when compared with fruit stored at lower temperatures. Storage temperature had no significant effect on decay incidence. However, physiological breakdown was greatest in fruit stored at 10 °C. Rates of fresh weight loss increased with storage temperature, ranging from 0.35% to 1.17% per month for fruit stored at 0 to 10 °C, respectively. Contrary to previous reports, no evidence of chilling injury was found in cranberry fruit stored at 0 °C. Results suggest that cranberry fruit should be stored at 0 to 7 °C and 75% to 82% RH to retain marketable fruit.

Abstract The objective of this study was to evaluate the effect of modified atmosphere (MA) and 1-methylcyclopropene (1-MCP) treatment on low storage temperature (1.5 °C) and 1-MCP treatment on high storage temperature (8.0 °C) on fruit quality of ‘Laetitia’ plums, mainly on internal browning. The treatments evaluated were 1.5 °C; 1-MCP (1.0 µL L-1) + 1.5 °C; MA + 1.5 °C; 1-MCP + MA + 1.5 °C; 8.0 °C; 1-MCP + 8.0 °C. Fruit were stored for 30 and 40 days, followed by three day of shelf life. For fruit stored at 1.5 °C, the treatment with 1-MCP associated to MA provided higher flesh firmness, less intense skin red color and reduced occurrence of internal browning in comparison to the fruit stored at 1.5 °C of the remaining treatments, for both periods of storage. In fruit not treated with 1-MCP and stored at 8.0 °C there was no occurrence of internal browning, despite of lower flesh firmness and more intense red color of the skin and flesh in comparison to the fruit stored at 1.5 °C. The treatment with 1-MCP in fruit stored at 8.0 °C delayed those changes of flesh firmness and red color of the skin and flesh assessed after 30 days of storage, followed by three days of shelf life. The MA, regardless of 1-MCP treatment, had fruit with higher production of acetaldehyde after 30 days of storage, and ethanol after 30 and 40 days of storage at 1.5 oC. In fruit stored at 1.5 °C without MA, the treatment with 1-MCP reduced the production of ethyl acetate, acetaldehyde and ethanol. Fruit stored at 8.0 °C, regardless of 1-MCP treatment, had the lowest production of acetaldehyde and ethanol.

AbstractThe effect of storage temperature and ozone treatment on the post-harvest quality of cucumber and tomato was investigated. Cucumber and tomato were stored together with or without gaseous ozone treatment at 20 °C and 14 °C for 16 days. Firmness, color, weight loss, DA index and decay percentage of samples were evaluated during storage period. The results showed that the combination of ozone treatment and cold storage could maintain the quality of these horticultural products and decreased the decay incidence. Additionally, this combination also reduced the weight loss of samples during storage. Furthermore, ozone treatment maintained the green skin color of cucumber. No sign of chilling injury occurred during storage at 14 °C. Commodities stored with approximately 0.1 ppm gaseous ozone at 14 °C retained the firmness compared to other treatments until the end of the experiment. This study suggests a promising use of gaseous ozone treatment in storage chamber where ethylene-producing and ethylene-sensitive vegetables are stored together.

SummaryUltra-high-temperature (UHT)-treated milks containing a range of dissolved O2 levels were prepared using both direct and indirect UHT processes. The O2 content of directly processed UHT milk had a significant influence on the changes in the level of cooked flavour in the product during storage over a 12-week period. At storage temperatures of 2 and 20°C, a noticeable improvement in flavour could be achieved by O2 control. In general, samples with a head-space sufficient to yield an initial of 60–100 mm were most preferred. The effect of O2 control on samples stored at 38°C was only minor when compared with the marked decrease in acceptability of flavour occurring due to the high storage temperature.Directly processed samples stored at 20°C all gelled at 14 weeks while those stored at 2°C showed no evidence of gelation after 36 weeks. Storage at 38°C gave rapid flavour deterioration, bitterness at 7 weeks and gelation at 10 weeks.All indirectly processed samples were found to be severely cooked under the conditions employed, and any differences in flavour due to differing O2 contents were masked by the intensity of this flavour.
