The use of natural products as coatings to preserve the fruit quality during storage is an important step to maintain food safety for consumer health. The use of microalgae in coatings, therefore, may be promising in the preservation of mango. The present work had the objective to evaluate the effect of coatings based on Chlorella sp. on the postharvest preservation of ‘Tommy Atkins’ mango during storage at room temperature (23 °C). We carried out a completely randomized design experiment consisting of 0%, 1%, 2%, 3% and 4% of Chlorella sp., using 10 fruits per treatment (n = 10). Analyzing the L*, a* and, b* indices, in the peel and the pulp of the mango fruit, we observed a delay in the ripening with the increase of the biofilm concentration. The firmness of the pulp and maintenance of the organic acids of the fruits were higher in the treatments with a large amount of Chlorella sp. The use of biofilm with Chlorella sp. at 2% preserved the quality of ‘Tommy Atkins’ mango until ten days of storage, at 23 °C and 42% RH.

The sap or latex injury in mango reduces fruit quality as it causes skin blemish during harvesting and postharvest handling. Sap volume and visual quality of ‘Carabao’ mango as affected by different harvest times during the day (every hour from 7:00 AM to 5:00 PM), delay in cutting (hourly up to 6 h) of the pedicel at either the pedicel base or at the abscission zone and different desapping agents applied 1 or 7 h from harvest were assessed. Sap injury was assessed by allowing the sap to flow on the fruit after re-cutting the pedicel at the abscission zone. Sap volume was measured during harvesting while sap injury, days to table ripe stage, visual quality, weight loss, degree of anthracnose and stem end rot were assessed during fruit storage. The experiments were laid out using the completely randomized design. Sap volume ranged from 0.06 to 0.25 mL fruit-1. The lowest sap volume was recorded in fruit harvested in the afternoon between 1:00 and 5:00 PM, while the highest volume was noted at 7:00 and 10:00 AM. The relative humidity of the air was highest at 7:00 AM. Better quality at table ripe stage was noted in mango fruit harvested at 1:00 - 2:00 and 4:00 - 5:00 PM. Sap injury at different harvest times did not vary. The delay in the destemming up to 6 h and the location of cut or pedicel length did not affect sap volume and fruit quality. However, the cutting of the pedicel at the abscission zone rather than at the pedicel base tended to result in better quality, which helped delay fruit ripening. All desapping treatments, such as 1.0 % alum, 1.0 % detergent, 0.5 % lime [Ca(OH)2], and water, could control sap injury. Untreated fruit showed longer shelf life due to a lower degree of anthracnose. Stem-end rot did vary among desapping agents. Among the desapping treatments, water is found to reduce sap damage better. Harvesting later in the day, cutting at the abscission zone, and washing mangoes with water can reduce sap or latex damage in ‘Carabao’ mango.

This research was aimed to determine the quality properties, the microstructure of chicken sausage and Thiobarbituric acid (TBA) values with locally Indonesia red beetroot powder. The main ingredients of chicken sausage-making in this research were broiler chicken, filler, binder, beetroot powder, and spices. Red beetroot powder function as a filler was substituted tapioca starch in chicken sausage batter in three different levels. The combination of red beetroot powder with level 0, 1.0, 2.0 and 3.0% of total batter and shelf life at room temperature for 0, 1, 2 and 3 days. Each treatment consisted of five replications. The variables observed using quality properties (moisture, ash, fat, protein, crude fiber and calorie), microstructure and peroxide value of chicken sausage. The data of quality properties and peroxide value were analyzed by using one-way analysis (ANOVA) of Completely Randomized Design. The differences between means were analyzed by Duncan's New Multiple Ranges Test. The data of microstructure was analyzed by descriptive analyses. The moisture, protein, fat and ash contents for chicken sausages were significantly different (p<0.05). The chicken sausage with 2% substitution of beet powder produced chicken sausages with a high protein content of 14.77±0.02% while a low-fat content is 0.42±0.01%. Thiobarbituric acid (TBA) values of chicken sausages increased throughout the three days of room temperature storage (38°C). Chicken sausage formulated with red beetroot powder showed a significantly lower TBA value compared to the samples without red beetroot powder (p<0.05). In conclusion, a higher level of beetroot powder will improve the quality of chicken sausage and also the microstructure. The best level of beetroot powder addition was 2.0%. The addition of beetroot powder able to maintain fresh sausage conditions up to 2 days of storage at room temperature.

Aims: This study assessed the initial effect of experimental pruning (EP) or grower’s pruning (GP) of cactus pear fruiting cladodes on fruit yield (FY), fruit size distribution (FSD), and fruit quality (FQ) at harvest and after storage. Study Design: Treatments were arranged in a completely randomized design with eight or ten replicates, with a single plant as replicate, for EP or GP, respectively. Place and Duration of Study: The experiment was set up in a drip-irrigated commercial orchard of ‘Roja Lisa’ cactus pear [O. ficus-indica (L.) Mill.] plants located at Santa Fe, Jerez, Zacatecas, México, from February to August 2006. Methodology: The EP considered two agronomic practices: 1) exposing the center of each plant while eliminating unproductive cladodes and those shading other cladodes and 2) concentrating fruiting cladodes in the outer part of the plants. The GP randomly eliminated some cladodes from the central part and around the plants only. Treatments were arranged in a completely randomized design with eight or ten replicates, with a single plant as replicate, for EP or GP, respectively. The response variables were: FY, FSD, and FQ at harvest and after storage. The FQ attributes were: mean fruit mass (MFM), flesh firmness (FF), total soluble solids concentration, pulp and peel mass, dry matter concentration, and fruit water loss (FWL) during storage. Results: EP increased MFM by 42% over GP and produced 15% more marketable fruit (fruit equatorial diameter from 5.0 to 7.0 cm), but FY was reduced by 39%. The FF was higher in EP fruit than GP fruit after storage. The other FQ attributes were similar in both pruning treatments, both at harvest and after three weeks at room temperature. The FWL was also similar under both pruning systems. More targeted pruning has the potential to increase the productivity of cactus pear orchards. Conclusion: Experimental pruning increased fruit size and the percentage of commercial fruit, but reduced both overall and commercial fruit yields. After three-week storage at room temperature, flesh firmness remained greater in EP fruit. Fruit water loss was not influenced by pruning treatments during the storage.

A field trial was conducted during 2015 and 2016, to study the effect ofgrowth regulators on growth, flowering, yield and fruit quality of strawberry cv. Chandler. The experiment was laid out in completely randomized design with 16 treatments viz.CPPU at 1, 2 and 4 ppm, GA3 at 25, 50 and 75 ppm, Promalin at 2, 4 and 6 ppm, GA4+7 at 5, 10 and15 ppm, NAA at 10, 20 and 30 ppm and control (water spray) and each treatment was replicated thrice. The results revealed that the plants sprayed with 15 ppm GA4+7 two weeks before flowering significantly reported highest plant height (33.43 cm), leaf area (239.70 cm2), number of flowers (31.94), fruit set (87.45 %), number of fruits per plant (29.02), yield (540.01 g/plant), fruit length (53.63 mm) and fruit diameter (37.19 mm) and fruit weight (23.70 g) as compared to control. This treatment resulted in 196.36 % increase in yield and 56.22 %in fruit weight over control. Plants sprayed with 6 ppm promalin also showed significant improvement in vegetative growth, fruit size, yield and fruit quality, which resulted in 137.92 % increase in yield and 51.81 % increase in fruit weight over control. Hence, it is concluded that foliar spray of 15 ppm GA4+7 applied 2 weeks before flowering is beneficial in improving growth, yield and fruit quality of strawberry plants.

It is very challenging to the quality of the papaya culture&rsquo;s fruits (Carica papaya L.) after the crop, especially due to their significance to the international market, that is, their elevated exportation demands. The purpose of this work was the application of biodegradable coatings composed of Scenedesmus sp. and Chlorella sp. associated or not with pomegranate seed oil in &lsquo;Golden&rsquo; papaya and to evaluate their effect in the conservation powder-crop. The installation of the experiment was carried out in a completely randomized design, with a 6 x 6 factorial outline, that is, six concentrations (C: control; SO: 0.5% of Scenedesmus sp. + 0.3% of pomegranate seed oil; S: 0.5% of Scenedesmus sp.; CO: 0.5% of Chlorella sp. + 0.3% of pomegranate seed oil; CH: 0.5% of Chlorella sp.; O: 0.3% of pomegranate seed oil) and six evaluation periods (0, 3, 6, 9, 12, and 15 days), stored at a temperature of 18&plusmn;2 &deg;C with 60&plusmn;5% RH with three repetitions of two fruits per portion. The use of coverings composed of Scenedesmus sp. and Chlorella sp. in association or not with pomegranate seed oil was proven efficient in the reduction of the breathing tax of &lsquo;Golden&rsquo; papaya, delaying the ripening process, and therefore representing a promising alternative for these fruits&rsquo; powder-crop conservation. The coating composed of 0.5% of Chlorella sp. + 0.3% of pomegranate seed oil (CO) provided a better powder-crop conservation of &lsquo;Golden&rsquo; papaya during 15 days of storage.

Despite the importance of the Amazonian species Schizolobium amazonicum, there is still no official protocol to favor the germination process of its seeds. The objective of this study was to evaluate methods of overcoming dormancy of paricá seeds and the quality of seedlings produced. The work was carried out at the Federal Institute of Education, Science and Technology of Tocantins-Campus Araguatins. The experimental design was a completely randomized design with seven treatments and four replications. The treatments consisted of: intact seeds; lateral mechanical scarification of the tegument with electric emery for 2 seconds; lateral mechanical scarification of the tegument, using sandpaper number 50 for 1 minute + immersion in water at room temperature for 12 hours; chemical scarification of the tegument with caustic soda at 20% concentration for 30 minutes; chemical scarification of the tegument with caustic soda at a concentration of 20% for 45 minutes; immersion in water at 80 ºC + stay in water (room temperature) for 12 hours; immersion in water at 90 ºC + stay in water (room temperature) for 12 hours. The treatment with lateral mechanical scarification of the integument using electric emery for 2 seconds is the most suitable for overcoming dormancy in paricá seeds. Methods of overcoming dormancy had no influence on the quality of paricá seedlings.
