“…Higher ratio values indicate a more significant presence of sugar content than acid content in a fruit, showing the predominance of sweetness in the fruit. Silva et al (2013) obtained the highest mean ratio (94.32) at eight days of storage.…”

“…On the one hand, the early harvest hinders fruit maturation; on the other hand, late harvest shortens the storage period since the fruits are close to the senescence stage and therefore are subject to greater dehydration (Silva, Mizobutsi, Mizobutsi, Cordeiro, & Fernandes, 2013). Thus, in both situations, the fruits become more susceptible to physiological disorders than when harvested at the appropriate time.…”

Determination of the harvest time of sugar apples (Annona squamosa L.) in function of carpel interspace

et al. 2020

Sugar apples have attracted attention in recent years due to their medicinal and nutritional properties. However, the shelf life of sugar apples is one of the most concerning problems owing to their perishability. This work aimed to determine the ideal harvest time for sugar apple fruits in relation to different classes of carpel interspaces. Therefore, fruits were classified into three stages according to the carpel interspace: stage 1 (0.0 - 2.0 mm); stage 2 (2.1 - 3.0 mm); and stage 3 (3.0 - 4.0 mm). After harvesting, the fruits were evaluated daily in the laboratory regarding their physical and physicochemical aspects until they reached the point of consumption (horticultural maturation). The following variables were evaluated: fruit diameter and length (mm); fruit, peel, pulp, and seed masses (g); color index, including the chromatic attributes L* (luminosity), C* (chroma), and h* (hue angle); bark firmness (N); soluble solids (°Brix); titratable acidity (g citric acid 100 g-1 of pulp-1); pulp yield; and ratio SS/TA. Fruits at stage 3 showed larger diameters, less firmness, and better chromaticity means. Fruits at stages 2 and 3 had eight days of postharvest life. However, fruits at stage 2 took longer for 50% of the fruits to be ready for consumption. The results demonstrate that stages 2 and 3 can be determinants for the harvest time of sugar apples.

“…African Pride, unpackaged, after 15 days at 14.5°C showed firmness of 10N [22]. The application of 1-MCP (1-methylcyclopropene) for 8 hours in the concentration 600 nL L -1 retarded the maturation by reducing loss of firmness of the sugar apple [23] and atemoyas cv. Gefner [24,25].…”

“…Gefner [24,25]. Sugar apple stored at 15°C for 21 days had a loss of firmness twice as fast as those untreated with 1-MCP [23], while in the atemoyas the loss of firmness was nine times smaller at 25 days at 15°C, compared to the untreated ones [25]. When associated 1-MCP and modified atmosphere (film of low density polyethylene, LDPE, of 16 μm) atemoyas maintained firmness four times greater at 20 days at 15°C [24].…”

Aims: The objective of this study was to evaluate the effect of the modified atmosphere under refrigeration for 28 days in the Atemoya Gefner. Study Design: Experiment 1 and 2 was installed in a completely randomized design, in a factorial 1x4 and 2x8, respectively. Place and Duration of Study: The experiment was conducted in a cold chamber at the State University of Montes Claros, Brazil, between July and August 2018. Methodology: In the first, the percentage of fruits that presented cold injury (CI) in unpackaged fruits and stored at 15°C for six days was visually evaluated. In the second experiment two pack were used and stored at 15°C and evaluated the physical and chemical characteristics. Results: In the first experiment, from the 2nd day 100% of the fruits showed CI that progressed to stage 3 on the 6th day of storage. This result justifies the need to store the atemoya under modified atmosphere under 15°C for 28 days. It was found at the end of 28 days, experiment two, that the packages 1 and 2 showed quality fruits, with characteristics of ripe fruits, with 22 °Brix average values, reduced titrable acidity, light green color peel and good lightness. The pack1 showed better weight maintenance, with 1.54% of fresh weight loss against 2.36% for pack2. Conclusion: There was a higher solubilization of total sugars and non-reducing sugars in pack1, being this the most indicated for atemoya fruits grown in northern Minas Gerais.

“…Because sugar apple has a climacteric respiration pattern, the fruit has a rapidly maturing and perishing behaviour during the post harvesting period under favorable conditions (Silva et al, 2013). Among the techniques employed to increase shelf-life of fruits and vegetables are the use of controlled packaging (Reis et al, 2014).…”

PHYSICO-CHEMICAL CHARACTERIZATION OF SUGAR APPLE (Annona squamosa L.) FRUITS STORED WITH PVC FILM IN DIFFERENT CONTROLLED TEMPERATURES

2018

View full text Add to dashboard Cite

<p class="BodyAA">Sugar apple (<em>Annona squamosa</em> L.) is tropical climacteric fruit with a very short shelf life, ripening completely in just a few days under favorable conditions. Among the techniques employed to increase the time of conservation are the use of modified atmosphere and cooling. The objective of this work was to study the use of PVC film and cooling to increase the shelf-life time of fresh fruits of sugar apple. Fruits were harvested at the stage of physiological ripeness, stored in paperboard boxes (33cm x 27cm x 10cm) covered or not with PVC film and placed in refrigerators with temperatures set to 18ºC, 21ºC, 24ºC and room temperature (average 27°C±2). The experiment was set in a completely randomized design and the treatments evaluated in a fatorial scheme 2x4 (with and without PVC film and 4 temperatures) with four replications and three fruits per plot. The results showed that lower temperatures did not affect physical-chemical characteristics of the fruits, but increased the time of post-harvesting conservation by three fold. The use of PVC film helps to preserve the weight and the external and internal quality of the fruits, but it reduced the amount of total solid soluble of the fruit pulp on the consumption point.</p>
