Purple Passion Fruit

Colombia is the country with the greatest genetic diversity in passion fruit species, some of which are cultivated on an area of approximately 13,673 ha. Each variety must be planted at a suitable altitude under optimal conditions to obtain the best quality. Regarding plant nutrition, potassium has the greatest influence due to the effect of its application on the yield increase, ascorbic acid content and lifecycle to harvest. Adequate water increases the percentage of the marketable quality and amount of fruit juice, and the use of rootstocks does not significantly change the fruit quality. Ensuring a pollination of the flowers in cultivation is decisive for the fruit formation and its juice content. The species differ greatly in their quality, as purple passion fruit (Passiflora edulis f. edulis) is a fruit that develops the highest content of ascorbic acid, while sweet calabash (P. maliformis) forms the maximum amount of phenols and total antioxidant activity. The maturation and ripening of passion fruit is determined by the skin coloration, during which the Brix grades and the maturity index increase and the titratable acidity diminishes. Fruits harvested early in physiological maturity and with unripe peel color can be treated with ethylene in post-harvest, matching fruits that ripened in the plant. More research is needed in the improvement of the quality of the Passifloraceae. Giant granadilla (P. cuadrangularis) and sweet calabash have been studied less than banana passion fruit (P. tripartita var. mollissima), purple passion fruit, yellow passion fruit and sweet granadilla (P. ligularis). The last three species are the most exported fruits in the country.

Kiwifruit is very perishable especially at 20 °C. The quality of kiwifruit with 1-MCP treatment stored at 20 °C in modified packages was investigated. Three different polyolefin films, including 0.03mm thickness polyethylene (PE), 0.03mm and 0.05mm thickness poly (vinyl chloride) (PVC) films, were used as packaging films. Kiwifruit were fumigated with 1-MCP to delay ripeness and then packaged with the three films and control (air). O2 and CO2 concentrations in the packages, flesh firmness, soluble solids concentration (SSC), titratable acidity (TA) and ascorbic acid were measured. MAP treatments could postpone the increase of TTS, inhibit the reduction of TA, and avoid the decrease of flesh firmness. Kiwifruit packaged in 0.05mm PVC obtained 33% TA more than control fruit and approximate 25 % retention of initial firmness. However, MAP didn’t maintain more ascorbic acid content of kiwifruit. In conclusion, MAP using polyolefin films combination 1-MCP treatment, especially 0.05mm PVC, might be more effective for preserving the quality of kiwifruit.

The increased consumption of acerola in Brazil was triggered because it is considered as a functional food mainly for its high ascorbic acid content, but the fruit also has high nutritional value, high levels of phenolic compounds, total antioxidant activity, anthocyanins and carotenoids in its composition. The objective was to evaluate the chemical, physical-chemical and antioxidant activity of eight varieties of acerola tree. The acerolas used in the research were the harvest 2015, 8 varieties: BRS 235 - Apodi, Mirandópolis, Waldy - CATI 30, BRS 238 - Frutacor, Okinawa, BRS 236 - Cereja, Olivier and BRS 237 - Roxinha, from the Active Bank Germplasm APTA Regional Alta Paulista in Adamantina - SP. Avaluated the following attributes: pH, titratable acidity, soluble solids, reducing sugar, instrumental color, ascorbic acid, total phenolics, flavonoids and antioxidant activity. The design was completely randomized, 8 varieties and 3 replications of 20 fruits each. Acerola fruit of the analyzed varieties prove to be good sources of phenolic compounds and antioxidant activity, ensuring its excellent nutritional quality relative to combat free radicals. The variety BRS 236 - Cereja presents higher ascorbic acid content, antioxidant activity and phenolic compounds, and the lowest value for flavonoid, which was higher than the other cultivars, especially Olivier and Waldy CATI-30.

ABSTRACT The family farming from the Borborema Territory-PB, Brazil, produces sweet oranges that supply the regional market. In this context, it is necessary to define standards of identity and quality, as well as to quantify the bioactive compounds in the fruit, in view of adding value and creating more competitive markets. This work sought to evaluate the quality, bioactive compounds and total antioxidant activity (TAA) of oranges from family farming. A 3x3 factorial completely randomized design was used, with three cultivars (Baía, Comum, Mimo-do-Céu) and three maturity stages (predominantly green, green/yellow, yellow), with 60 replications of 1 fruit for the physical evaluations, and 4 of 15 fruit for the others. The whole fruits were evaluated by color index, length, diameter, fresh weight and firmness. The juice was assessed for yield, pH, soluble solids (SS), titratable acidity (TA), SS/AT ratio, and ascorbic acid. Total extractable polyphenols (TEP) and ABTS•+ and DPPH• total antioxidant activity (TAA) were measured in the juice and albedo. The 'Baía' and 'Mimo-do-Céu' oranges presented quality parameters aligned with the CEAGESP standards. On average, the ascorbic acid content was higher than 45 mg 100 g-1, with ‘Mimo-do-Céu’ presenting the highest content (50.26 mg 100 g-1). During maturation, the firmness decreased, and the SS, TEP and TAA of the juice and the albedo increased. In general, the TEP content was about eight-fold higher in the albedo than juice, corresponding to the much higher TAA in this portion, thereby highlighting its higher functional potential, especially for ‘Baía’ orange.

Passion fruit nectar was developed from yellow and purple passion fruit separately and also by blending both yellow and purple fruits, in different combinations of TSS and juice. It was initially subjected to organoleptic evaluation to determine the best combination of TSS and juice content in nectar. Organoleptic evaluation revealed that passion fruit nectar containing 20% juice and 20°Brix was more acceptable in all the three categories (yellow and purple separately, and yellow blended with purple). Total soluble solids, non-enzymatic browning, reducing, non- reducing and total sugars increased while, titratable acidity, vitamin C, total carotenoids, total phenols and total flavanoids decreased during storage. Organoleptic quality of passion fruit nectar declined during storage in all the treatments. The rate of decline was faster in nectar stored under ambient conditions compared to those stored under refrigerated condition. Microbial load in all the samples was within the acceptable limits even after three months of storage.

The objective of this work was to compare the effects of four different concentrations of cassava starch film and storage temperature on shelf life and the quality of a genotype of acerola from the Germplasm Active Bank (GAB) of Federal Rural University of Pernambuco, Brazil. Sound orange-reddish acerola fruits were washed with a chlorine solution (100 mg.L-1 active chlorine) and randomly distributed into different lots. The fruits were dipped for 3 min in a cassava starch suspension with concentrations of 1, 2, 3 and 4% (w/v) and the control without coating, stored at 10ºC (85% RH) and 22ºC (85% RH). The total soluble solids (TSS), pH, titratable acidity (TA) and ascorbic acid (AA) were determined at harvest and regular interval during storage. The use of cassava biofilm at 1% on acerola fruits maintained the highest ascorbic acid content and the temperature of 10ºC extended storage life. The fruits coated with 1 and 2% biofilm could be stored for a period up to 15 days at 10ºC, with acceptable quality characteristics.

ABSTRACT Mineral nutrients have important role in plant metabolism, acting on specific vital metabolic pathways for the cell. Among the nutrients, we highlight silicon (Si), for promoting growth, improving post-harvest quality and plant productivity, as well as being able to induce resistance to pest and disease. In this sense, this study aimed to evaluate the productivity and post-harvest quality of strawberry fruits cultivars Aromas and Albion cultivated in organic system with four doses of foliar applications of SiO2 in pre-harvest (0, 5, 10, 15 g L-1), and refrigerated storage (8 days under refrigeration and 1 day at room temperature). The valuated traits were: mass loss, fruit mass, productivity, fruit firmness, soluble solids, titratable acidity, total phenolics, total anthocyanins, ascorbic acid and soluble solids titratable acidity ratio. The cultivar Aromas presented higher productivity per area (33.05 t ha-1), and more fruits per plot (479.42); however, higher average fruit mass was obtained in cultivar Albion (24.44 g), presenting better-quality fruits for fresh market. Soluble solids content, SS/TA ratio and ascorbic acid content were not influenced by silicon doses, however, refrigeration during 8 days and 1 day at room temperature provided reduction of fruit firmness, titratable acidity and, ascorbic acid content and increased soluble solids content and SS/TA ratio. Refrigeration attenuated significant reductions in anthocyanin content and, in addition, foliar silicon application promoted higher levels of anthocyanins in the fruits of both strawberry cultivars, increasing with the applied dose. The application of silicon was also efficient in maintaining fruit firmness of both cultivars.

<p>Dietary recommendations include the consumption of fresh apples and processed apple based products mainly for the antioxidant properties associated to the polyphenols, and vitamin C content. Thermal treatment, generally used to extend shelf life of fruit based foodstuff, can affect the quality. 5-hydroxymethylfurfural (5-HMF), reducing sugars, ascorbic acid, and the total antioxidant activity in bio available fraction after <em>in vitro</em> digestion, have been evaluated in 16 apple-based nectars (fruit content: 30-60%), 15 apple-based juices (fruit content 100%) and 5 apple-based puree. Observed data indicate a 5-HMF values ranging from 0.06 mg/L in juices to 28.61 mg/L in nectars. The reducing sugar amount did not vary significantly between the three analysed typology of apple derivatives, while the ascorbic acid content was quite high compared to reported literature data. The antioxidant activity after an <em>in vitro</em> digestion showed values ranging from 0.21 to 7.68 mmol of Trolox in juices, and puree, respectively.</p>

High Antioxidant Activity

Blackberries (Rubus spp.) have significant nutraceutical properties, providing phenolic compounds for the consumers. These compounds are useful to human health due to their high antioxidant activity. However, most blackberries destined for fresh markets become unmarketable in 2 to 3 days due to decay and leakage, because they have thin and fragile skin. The present study was aimed to investigate the effect of salicylic acid (SA) and calcium chloride (CaCl2) on extending the postharvest quality and bioactive compounds of blackberry during refrigerated storage. Blackberry fruits cv. ‘Jumbo’ were dipped in 2% CaCl2, or in 2.0 mM salicylic acid (SA) for 10 min. Total soluble solids contents, titratable acidity, pH, ascorbic acid contents, total phenolics contents, and total antioxidant activity were investigated initially on 4th, 7th, or 10th day (d) of storage. Changes in fresh weight, titratable acidity, ascorbic acid and total phenol contents were markedly delayed by both treatments. Berries treated with 2 mM SA or 2% CaCl2 exhibited markedly better visual quality during the storage period. Considering the overall findings, this study revealed that postharvest SA or CaCl2 applications maintained the storage-life and conserved the valuable marketing features of blackberries over 10 d in cold storage, presumably due to their inhibitory effects on fruit senescence.
