Cashew Apple

This work aimed to study beverages' storage stability based on cashew apple pulp and honey during 120 days. Three formulations were prepared: F1 (75% of cashew apple pulp and 25% of honey; F2 (60% of cashew apple pulp and 40% of honey) and F3 (50% of cashew apple pulp and 50% of honey). The formulation F1 showed the highest content of ascorbic acid after storage (95.74 mg.100mL). The pH did not show variation between the formulations studied. Soluble solids showed significant differences during storage and were consistent with the drink's honey content, ranging from 28.8 to 30.0 for F1, from 36.5 to 40.1 for F2, and 44.3 to 47.7 for F3. The content of carotenoids and phenolic compounds decreased during storage time. The preparation of beverages based on cashew apple and honey presented an alternative to adding value to the cashew apple pulp.

Passion fruit juice, pure and sucrose sweetened (1:1, w:v), was frozen and stored for 8 months in freezers. The effect of storage time and sucrose addition on physicochemical properties of the juices was evaluated, in the fresh juice, and then every two months in the stored samples. Concentration of soluble solids, organic acids, total and reducing sugars and ascorbic acid, as well as pH were not affected by storage time. Initially sucrose addition modified the juice color, but not during storage time, while the natural juice became more yellow during storage. β -carotene content decreased as a function of storage time, 51.3 % in the pure juice and 29.7 % in the sweetened juice.

ABSTRACT: Brazilian Cerrado fruits have a great diversity of bioactive compounds, with significant relevance for fresh consumption and industrial processing. The uvaia (Eugenia pyriformis Cambess) stands out among these fruits, seeing that this species contains high phenolic compounds and ascorbic acid levels. However, its technological and nutritional potential is still little explored industrially. This research aimed to develop three uvaia nectar formulations and to evaluate its stability during 90 days of storage. The formulations were made with 30%, 40%, and 50% of uvaia pulp, corresponding to F1, F2, and F3 formulations, respectively, which were characterized for pH, total titratable acidity, soluble solids, ascorbic acid, and total phenolics during 0, 30, 60, and 90 days of storage at room temperature. A significant pH reduction was observed after 30 days of storage for all nectars. The acidity and ascorbic acid levels increased in proportion to the addition in the pulp concentration of the formulations. The ascorbic acid content reduced over the storage period and remained higher for the formulations F2 and F3. The concentration of phenolic compounds was higher in the nectar containing relevant levels of uvaia pulp concentration, which increased throughout 30 days of storage, however, with a decrease after this period. The formulations containing 40% and 50% of uvaia pulp showed higher concentration and better stability of bioactive compounds. Uvaia can be considered an effective raw material for the development of a novel beverage with important nutritional and bioactive properties.

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 Atlantic Forest is recognized as a biome rich in biodiversity. Cambuci trees (Campomanesia phaea) produce fruits that may be consumed as both fresh and processed forms but are still underutilized. The aim of this study was to describe the physicochemical characteristics and bioactive compounds in cambuci fruits from Brazilian Atlantic Forest, located at Natividade da Serra-SP, Brazil. Cambuci fruits of the fifty-nine accessions were characterized according to fresh weight, pulp yield, peel percentage, longitudinal and transversal diameters (LD and TD, respectively), pH, soluble solids content (SSC), titratable acidity (TA), SSC/TA ratio, ascorbic acid, total phenolic compounds content, and antioxidant activity using the DPPH assay. The soluble solids contents varied from 5.10 °Brix to 11.00 °Brix. The titratable acidity varied from 1.29 to 2.90 g citric acid 100 g-1. Ascorbic acid content was of 31.12 to 139.38 mg 100 g-1. Total phenolic compounds varied from 330.5 mg GAE 100 g-1 to 3,526.04 mg GAE 100 g-1. The antioxidant activity was of 65.03 µmol Trolox g-1 fruit pulp (fresh weight) to 199.78 µmol Trolox g-1 fruit pulp (fresh weight), a factor of 6.7 difference between the extremes. These results showed cambuci fruits presented as rich source of ascorbic acid, total phenolic compounds, and with high antioxidant capacity.

ABSTRACT The objective of this work was to evaluate the content of phenolic compounds, anthocyanins and flavonoids extracted with 80% ethanol and water, and antioxidant capacity (DPPH and ABTS) of five blackberry cultivars produced in Western Paraná, Brazil. Brazos, Tupy, Arapaho, Choctaw and Guarani blackberries were studied. Soluble solids, titratable acidity and ascorbic acid of fruits were also characterized. Total phenolic compounds ranged from 8.23 to 14.98 mg GAE g-1 (f.w.) and Arapaho cultivar exhibited the highest contents in both solvents. Anthocyanins ranged from 2.57 to 9.42 mg ECy3glu g-1 (f.w.), being the solvent ethanol 80% more efficient than the water, and Choctaw cultivar showing the highest content. Flavonoids ranged from 0.46 to 1.14 mg EQ g-1 (f.w.) and Guarani cultivar showed the highest content. High linear correlations were found between total phenolics and antioxidant capacity in both extraction solvents. However, linear correlations between anthocyanins and antioxidant capacity were observed only for the aqueous solvent. Ascorbic acid ranged from 87.87 to 134.09 mg 100 g-1, with emphasis on Brazos cultivar. The aqueous extract showed greater ability to scavenge ABTS radical, but the ethanolic extract was more efficient for the DPPH radical. Blackberries produced under Western Paraná conditions showed high levels of antioxidants with emphasis on Arapaho cultivar. This study showed that water and ethanol solvents influence different results on phenolic composition and antioxidant activity of blackberries.

Brazil is the third largest producer of fresh fruits in the world. Among fruits, berries such as strawberry, blueberry and blackberry can be highlighted for the benefits they provide to the body, owing to their presence of bioactive compound content. The phenolic compounds, especially anthocyanins and ascorbic acid, are examples of bioactive compounds that mainly function in the body as antioxidants. However, the processing steps that lead to the generation of derivatives from these fruits, are damaging to these compounds, often leading to their loss. Thus, the aim of this study was to physically and chemically characterize fresh berries (strawberry, blueberry and blackberry) and their jams, and also to quantify and to evaluate the antioxidant activity of bioactive compounds in berries and their jams. The following parameters were analyzed: moisture, ash, pH, titratable acidity, soluble solids, and color. The levels of total phenolic compounds, total anthocyanins, ascorbic acid content and antioxidant activity were measured. We concluded that there were significant differences in the chemical composition of berries and jams. There was also a significant loss of bioactive compounds due to processing, nevertheless these jams remain good sources of bioactive compounds, and are still considered important to promote some favorable health effects.

The present work evaluated the influence of calcium silicate on the polygalacturonase enzyme activity, respiration, ethylene, and the physicochemical characteristics on the post-harvest quality of two tomato hybrids. The experimental design was of randomized blocks, with four repetitions in protected cultivation environment. The treatments were distributed in a 2 x 5 factorial scheme, corresponding to the hybrids (Ivety and Natalia) and five doses of calcium silicate (0, 150, 300, 450 and 600 kg ha-1), which were applied on the same day as the pots were filled. Evaluations were carried out on the fruits, namely: ethylene production, fruit respiration, firmness, number of loculus, polygalacturonase activity, total carotenoids, lycopene, phenolic compounds, soluble solids content, pH, titratable acidity and ascorbic acid content.  The application of calcium silicate provided the reduction of ethylene production and fruit respiration. Natalia hybrid showed low polygalacturonase activity, this difference being due to genetic variabilityThe increase of calcium silicate doses provided the reduction of polygalacturonase enzyme concentration due to its constitution in the cell wall. The concentrations of lycopene, phenolic compounds, soluble solids, pH, titratable acidity and ascorbic acid in the fruits increased in response to the increasing doses of calcium silicate for 'Ivety'. Hybrids present distinct behaviors on the influence of the fertilization of tomatoes with calcium silicate, which can increase the post-harvest conservation and improve the physical-chemical characteristics of tomato fruits.
