Cucumis Melo L

The aim of our experiments was to investigate the internal quality parameters of some old melon and watermelon landraces or varieties whether they have any desirable characteristics. Measurements were carried out using 8 different types of melon (Cucumis melo L.) and 8 accessions of watermelon (Citrullus lanatus [Thumb]), which were self pollinated under greenhouse conditions. Besides the determination of dry matter content; soluble solids, titratable acidity of the fruit juices, investigation of carbohydrates, total phenol content was measured by spectrophotometer. Total antioxidant capacities were determined spectrophotometrically using the FRAP method. We found some accesions both among melon and watermelon varieties, which could be characterized by outstanding inner content.

Abstract The aims of this work were to determine which storage conditions can preserve the quince quality (Cydonia oblonga Miller, Rosaceae family), stored in three different rooms with controlled atmosphere (CA). Due to their reported high polyphenolic content in the fruit, three varieties of quinces, like Ekmek, Bereczhi and Tinella were stored and monitored for twelve months. During storage period, the following quality parameters were monitored: dry matter content (D.M.%), titratable acidity (TA), soluble solids (°Brix), firmness, antioxidant capacity and also content in total flavonoids and total polyphenols. After twelve months of storage, observations showed that quince from Tinella variety presented better quality parameters compared to quinces from Ekmek and Bereczhi varieties. As expected, keeping quinces in the presence of CO2content, respectively 2% and 5%, presented better physical and biochemical quality compared with those stored without CO2 (control).

Tomato Yield

The performance and suitability of different substrates for the soilless culture of tomato plants (<I>Lycopersicum esculentum</I> Mill., cv. Belladona) were studied over a 5-month period in a closed soilless culture system employing five different substrates (perlite, pumice or maize and their mixtures with 50% shredded maize stems in an unheated glasshouse). Plants grown in a maize stem-containing medium produced earlier fruits, followed by pumice. Plants grown in pumice and perlite substrates obtained lower total yield; a higher yield was associated with the addition of maize shredded stems. Pumice + 50% maize and 100% maize produced higher total number of fruits per plant. Fruit quality parameters such as mean fruit weight, fruit firmness, total soluble solids, titratable acidity, ascorbic acid and carotenoids were influenced by the treatment, while EC, pH and dry matter content were not. The results suggest that the addition of maize in perlite and pumice could improve inorganic substrates properties for tomato soilless culture, leading to higher yields and better fruit quality.

Melon hybrids (Cucumis melo L.) C-8 and H-5 from Hazera C.O. (Israel), were treated with two commercial wax coating, Primafresh at the original concentration, and Prolong at 1.5% (w/v). Fruits were sprayed with wax and stored for 5, 10, and 15 days at 10, 15, and 25C in storage rooms. Total soluble solids, titratable acidity, pH, reducing and total sugars, dry matter, electric conductivity, and pulp fruit color were analyzed. No difference was found to TSS; titratable acidity was high at 10 and 15C in fruits stored for 5 days. The C-8 hybrid showed the highest reducing and total sugar content at 10C. For both hybrids, dry matter content was reduced at higher stored temperature and longer storage time. The hybrid H-5 showed higher color a* value and a clear pulp color was increased in fruit at 15C.

Abstract Pepino dulce (Solanum muricatum Aiton) or Pepino has been growing to produce edible, juicy and attractive fruits. The imported fruits and national small scale of Pepino dulce production are currently stored and commercialized under the absence of postharvest handling recommendations. Therefore, this work aimed to evaluate the quality aspects of Pepino dulce fruits in distinct ripening stages, forms of packaging and conditions of storage. The trial was conducted in a 2x2x2 factorial scheme - 2 ripening stages (ripe and immature) x 2 forms of packaging (with and without wrapping in plastic film) x 2 conditions of storage (room: 25 °C ± 2 ºC and 57% ± 5% of relative humidity (RH); cold: under refrigeration 10 °C ± 2 °C and 85% ± 5% of RH) – in a complete randomized block design. Fruit quality attributes, such as vitamin C, chemical and phenolic content, fruit color (mesocarp), firmness, dry matter content, total titratable acidity (TA), total soluble solids and pH, were evaluated. Fruits showed a centesimal composition with low calories and a significant content of potassium (K), phosphorus (P) and magnesium (Mg), which can contribute to the daily supply of these elements. For commercialization purposes, the association of packaging (plastic wrapping film) and refrigerated storage (cold: 10 °C ± 2 °C and 85% ± 5% of RH) to maintain the characteristics of fruit quality after a 15 days period is more important than its individual use.

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.

The effects of prolonged ethylene exposure on external and internal quality parameters of tomato fruits were studied in order to explore the feasibility of its use as a nondestructive technique for screening immature and inferior quality fruit. `Agriset' and `CPT-5' tomatoes were hand harvested at Stage 1 (green) and held at 20°C and 50 ppm ethylene for 1-7 days. Each 24 hours, fruits reaching Stage 2 (breaker) were removed from C2H4 and transferred to 20°C air for subsequent ripening. Tomatoes were considered at edible maturity upon reaching full red-ripe stage and 4 mm deformation and final quality parameters were determined. For both cultivars, fruits which required prolonged C2H4 exposure to reach Stage 2 had lower overall visual appearance. `Agriset' tomatoes which required short exposure times to C2H4 (1 to 3 days) had somewhat higher quality than those requiring prolonged times (4 or 5 days). Days to reach edible maturity were 9.5 and 7.7, respectively. For the short exposure times, peel color was more intense (higher chroma value), while soluble solids content and total sugars were significantly higher (P = 0.05). Quality of `CPT-5' tomatoes was not adversely affected until requiring 6 or 7 days exposure to C2H4. Days to reach edible maturity decreased from an average of 12.5 to 11.0 for 1 to 5 or for 6 to 7 days exposure, respectively. For fruits requiring 7 days exposure, soluble solids content, total sugars and pH were significantly higher than for those reaching Stage 2 in fewer days. There were no significant differences in titratable acidity or ascorbic acid content for either cultivar.

The banning of ethylene dibromide put an end to the exportation of Venezuelan melon to the northamerican market and made it a need testing alternative treatments. Melons were purchased from a grower/exporter and alloted in groups of 24 to the following treatments: control, 0.5, 0.75 and 1 KGy, and dip in water at 53C for 1 min. alone and plus 0.5 KGy, then they were stored at about 23C and 70% RH during 2 to 3 weeks in two experiments in one season. All the treatments resulted in comparable ratings for sensory attributes and figures for soluble solids, titratable acidity and ascorbic/dehydroascorbic acid; the melons dipped in hot water showed the lowest decay. With the possible exception of the 1 KGy melons, the treated melons had attributes and lasted as least like the control ones, which indicates that the Galia cv. of melon grown in Venezuela tolerates irradiation with doses useful in quarantine and technological terms.

AbstractCrop load management is an important preharvest factor to balance yield, quality, and maturation in peach. However, few studies have addressed how preharvest factors impact metabolism on fruit of equal maturity. An experiment was conducted to understand how carbon competition impacts fruit internal quality and metabolism in ‘Cresthaven’ peach trees by imposing distinct thinning severities. Fruit quality was evaluated at three developmental stages (S2, S3, S4), while controlling for equal maturity using non-destructive near-infrared spectroscopy. Non-targeted metabolite profiling was used to characterize fruit at each developmental stage from trees that were unthinned (carbon starvation) or thinned (carbon sufficiency). Carbon sufficiency resulted in significantly higher fruit dry matter content and soluble solids concentration at harvest when compared to the carbon starved, underscoring the true impact of carbon manipulation on fruit quality. Significant differences in the fruit metabolome between treatments were observed at S2 when phenotypes were similar, while less differences were observed at S4 when the carbon sufficient fruit exhibited a superior phenotype. This suggests a potential metabolic priming effect on fruit quality when carbon is sufficiently supplied during early fruit growth and development. In particular, elevated levels of catechin may suggest a link between secondary/primary metabolism and fruit quality development.HighlightAn investigation of variable carbon supply conditions in peach fruit reveals that early metabolic priming is associated with quality development

Hot Peppers

The aim of this study was to assess phenotypic diversity in terms of fruit quality traits and yield, and also to establish valuable genotypes for breeding purpose suitable for different direction of use. Ten cultivars of hot peppers bred at VRDS Buzau were collected and fruit quality (dry matter content, fruit firmness, the total soluble solids, titratable acidity and ascorbic acid content) was evaluated at different ripening stages. A very highly significant difference (p<0.01) was found for the studied quantitative parameters, showing a great variability among the studied accessions. During ripening, the dry matter content, the firmness, the TSS content and the titratable acidity increase for all studied cultivars and there were significant differences between them. A broad range of variation was noted in Vitamin C content in both stages of maturity. In the present research work, a great variability among the studied accessions was found. Fully ripe fruits were found considerably richer in the bioactive factor than unripe fruits. Our results have selected two important genotypes: A12A, an accession suitable for obtaining chili powder, due to the his low content in dry matter and total soluble solids and accession A135 suited for fresh consumption and for long shelf life because it has a high firmness.

Spatial variation in soluble solids content (SSC) of fruits of apple (Malus ×domestica Borkh. cv. Red Delicious), cantaloupe (Cucumis melo L. Cantaloupensis group), grapefruit (Citrus paradisi Macf. cv. Indian River Ruby Red), honeydew melon (Cucumis melo L. Inodorus group), mango (Mangifera indica L. cv. Hayden), orange (Citrus sinensis L. Osbeck. cv. Valencia), peach (Prunus persica L. Batsch. cv. Windblow), pineapple (Ananas comosus L. Merr. cv. Kew) and tomato (Lycopersicon esculentum Mill.), and of bulbs of onion (Allium cepa L. Cepa group) and in dry-matter content (DMC) of potato (Solanum tuberosum L. cv. Russet Burbank) tubers was measured along three directional orientations (i.e., proximal to distal, circumferentially midway along the proximal to distal axis, and radially from the center of the interior to the outer surface). The pattern and magnitude of constituent variation depended on the type of product and the direction of measurement. Radial and proximal to distal variation was greater than circumferential variation in all the products tested. Honeydew had the highest radial variation with a SSC difference of 6.0 % and a cv of 22.8%, while tomato displayed lower radial variation with a cv of 1.0%. Pineapple had a proximal to distal SSC difference of 4.6% with a cv of 13.8%, while the difference in tomato was 0.6% with a cv of 5.1%. Circumferential variation of SSC in all products tested was <2% with cv ranging from 1.1% to 3.8%. The results confirm that considerable constituent variability exists within individual fruit and vegetable organs. This variability may affect the accuracy of calibration equations and their prediction capability. Therefore, within-unit constituent variability should be meticulously assessed when an NIR spectrometric method is being developed for the nondestructive quality evaluation and sorting of a product.
