The method and temperature of storage of a product are the basic agents that make it possible to prolong the post-harvest life of strawberries. In this context, this study aimed to evaluate the use of different packages with the passive modified atmosphere in the post-harvest quality of strawberry (cv. Camarosa). The strawberries were harvested and subsequently transported to the Laboratory of Drying and Post-harvest Storage of Agricultural Products, where they were stored in BOD, at 0ºC, and 90±5% relative air humidity. A completely randomized design was used, in a 3 x 5 factorial scheme (three packages: expanded polystyrene (EPS) packaging + polyvinyl chloride (PVC) film at 0 °C; polyethylene terephthalate (PET) packaging at 0 °C; and without packaging at 0 °C (control) x five analysis: at 0, 2, 4, 6, and 8 days of storage), with four replications per day for each treatment. Averages were compared by Tukey test at 5% probability. The variables, fresh mass loss, pulp firmness, pH, soluble solids (SS), titratable acidity (TA) and SS/TA ratio were analyzed. The tested packages had better results when compared to the control treatment. The use of polyethylene terephthalate (PET) packages at 0ºC had a less fresh mass loss during storage days, lower acidity reduction, and no significant decrease in pulp firmness.

Nutraceutical Properties

The plum is a fruit prized for its nutraceutical properties because of its high content of fiber and sorbitol, which aid in digestion; furthermore, it is characterized as containing antioxidant pigments and an antiseptic action with anthocyanins. These fruits are classified as climacteric and continue the process of respiration and ripening after harvesting; because of this, it is necessary to harvest early so they can withstand transport, which often causes the fruits to not reach the consumption maturity required by consumers. The effect of ethylene on the ripening of plum fruits was evaluated, for which a completely randomized design with 10 treatments was used, which resulted from the combination of two factors plus a control without applications. The first factor was the ethylene dose (100; 1,000 and 2,000 mg L-1) and the second factor was the length of exposure to the ethylene (5, 10 and 15 minutes). The fruits were stored at room temperature for 9 days. In the fruits treated with ethylene, a significant increase in the respiration index and total soluble solids was observed. Additionally, greater total titratable acids and firmness values were obtained with the control treatment than with the ethylene; similarly, the ethylene application increased the fresh mass loss in the plum fruits. Overall, differences between the fruits treated with ethylene and the control were observed, but not between the doses, indicating that the lowest ethylene dose (100 mg L-1) can obtain the desired uniformity in plum fruits.

Yogurt Drink

Orange yogurt drink is one of the diversivication of yogurt products, but syneresis still often occurs during the storage period which can affect consumer assessments. Therefore, it is necessary to add a stabilizer to overcome this problem. The purpose of this study was to determine the effect of different types of stabilizers and the concentration level of stabilizers added to the physicochemical characteristics and preference of orange yogurt drinks. Characteristics of yogurt drinks that were observed included pH values, Total Titrated Acid/TAT, Total Dissolved Solids/TPT, vitamin C, wheying off, viscosity, and organoleptic tests which included preference for color, aroma, texture appearance and taste of orange yogurt drinks This study uses a completely randomized design (CRD) with two factors, namely the type of stabilizer (Carboxy Methyl Cellulose/CMC, pectin, gum arabic) and the concentration of stabilizer (0.01%, 0.03%, and 0.05%). The results of this study indicate that pH value of the orange yogurt drink ranged from 3.907-4.058, total soluble solids (TPT) of the orange yogurt drink was 14.350-16,367 °Brix, vitamin C content of the orange yogurt drink was between 6.453-10.560 mg/100 g, and TAT value. 6.133 – 8.067%. The treatment of different types of stabilizers affects the physicochemical characteristics of orange yogurt drinks, including the value of pH, TPT, vitamin C, TAT, wheying off and viscosity. While the treatment of different concentrations of stabilizer affects the wheying off and the viscosity of the orange yogurt drink. The results of the interaction between the type and concentration of stabilizer significantly affect the value of pH, vitamin C, TAT, wheying off, viscosity also the value of preference for color, appearance and texture of orange yogurt drink.

The study was conducted to assess the effect of different waxing materials on the quality attributes of tomato fruits. A 2 x8 factorial experiment layout in complete randomized design with 16 treatment combinations and 3 replication was adopted.The materials that were used for the experiment are two (2) varieties of tomatoes (Pectomech and Power Rano) and seven(7) waxing material (shea butter, cassava starch, beeswax, and a combination of shea butter + cassava starch, shea butter + beeswax, cassava starch + beeswax, shea butter + cassava starch + beeswax) and a control. Results from the experiment indicated that all waxing treatments delayed the development of weight loss, firmness, pH, total soluble solids, and total titrable acidity. The results also suggested that edible wax coatings delayed the ripening process and colour development of tomato fruits during the storage period and extended the shelf life. However Beewax treatment and its combinations performed better than the other treatments. It was therefore recommended that locally produced wax such as Beewax, Shea butter, Cassava Starch treatments and their combinations could be a good technology for preserving the quality and extending the shelf life of fresh tomato fruit as well as maintaining the physical and chemical properties.

The Impact

Late pear cultivars, such as ‘Conference’, can be stored for a long period if kept in good storage conditions. A three-year study (2011–2013) compared the impact of six-month storage using four technologies—normal atmosphere, normal atmosphere + 1-methylcyclopropene (1-MCP), controlled atmosphere, and controlled atmosphere + 1-MCP—on the quality parameters of ‘Conference’ pears, such as mass loss, firmness, total soluble solids, acidity, antioxidant capacity, and the incidence of diseases and disorders. Additionally, the study analysed different storage conditions in terms of profitability, based on the market prices for pears in the seasons during which the pears were stored. The storage conditions had a very strong influence on the fruit quality parameters, and were found to affect most visibly the mass loss and the incidence of postharvest diseases and disorders. The storage of ‘Conference’ pears for 180 days in normal atmosphere is not economically viable, even if the fruit is subjected to 1-MCP treatment; at the same time, it is profitable to store ‘Conference’ pears in controlled atmosphere for the same period, no matter whether 1-MCP was applied or not.

This study aimed to evaluate the postharvest behavior of peach cv. Aurora 1 harvested in the Zona da Mata region of Minas Gerais in two ripening stages and kept under different storage temperatures. Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD) . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv. Aurora 1 harvested in the Zona da Mata region.

The number of studies on edible coatings that are used for extending the shelf life of fruits has steadily increased. For this purpose, it is necessary to choose raw materials with characteristics that maintain product quality. The objective of this study is to evaluate the effect of coatings of Chlorella sp. on the post-harvest conservation of ‘Tommy Atkins’ mango fruits. The experiment was conducted using a completely randomized design, and spray treatments (T) with 0%, 1%, 2%, 3%, or 4% of Chlorella sp. were applied to the fruits. After the treatments, the fruits were stored for 28 days (21 days at 10 °C and 42% relative humidity and 7 days at 25 °C and 42% relative humidity), and were analyzed on day 28. There was higher pulp firmness in fruits as the concentration of Chlorella sp. was increased, and the concentration of ascorbic acid was comparatively higher (22.17%) in fruits treated with 3% Chlorella sp. The percentage of soluble solids and the soluble solids/titratable acidity ratio were decreased as the coating concentrations were decreased. The use of Chlorella sp. at 1% and 2% allowed fruit maturation without compromising fruit quality attributes during the 28-day storage period.
