Extraction of tropical fruit juice using simple, efficient, and environmentally friendly technologies is gaining importance to produce high quality juices. Juice from pink-fleshed guava, pink-fleshed pomelo, and soursop was extracted using direct and indirect thermosonication methods by varying intensity, time, and temperature, and compared to those extracted using water bath incubation. Improvised models of juice yield, ascorbic acid, and total soluble solids responses were generated by eliminating insignificant model terms of the factors in full quadratic model using backward eliminating procedure. Main effects, 3D, or 4D plots for each response were developed based on factors that influenced the response. Results showed that the best extraction method for guava and pomelo juices were within indirect thermosonication method of 1 kW, 55 °C and 30 min, and 2.5 kW, 54 °C and 23 min, respectively. Direct thermosonication method at 10% amplitude, 55 °C for 2 to 10 min was more suitable for soursop juice. Thermosonicated extraction of tropical fruit juice can improve its juice yield, ascorbic acid content, and total soluble solids content.

Abstract The sugar-tasting abilities of four species of tanagers and two species of manakins were tested. Three tanager species were able to detect differences in diets containing 8%, 10%, and 12% sugar. In pairwise choice trials, they preferred the diet highest in sugar. Neither species of manakin discriminated among the three diets. This apparent difference in tasting abilities of tanagers and manakins may be a result of their fruit-handling techniques. Tanagers crush fruits in their bills, thereby releasing juices onto their tongues. Manakins swallow fruits whole; their tongues rarely encounter fruit juice. Hence, manakins' fruit-handling technique is poorly suited for sensing the taste cues in fruit juices. Variation in fruit sugar concentration is common within and among plant species and is great enough to be detected by birds. Birds probably have selected for sweeter fruits.

This study aimed to determine the effects of tropical fruit juice mixture (pomegranate, white guava, and Roselle) on biochemical, behavioral, and histopathological changes of β-amyloid- (Aβ-) induced rats. Formulation 8 (F8) of tropical fruit juice mixture was chosen for this present study due to its high phenolic content and antioxidant capacity. Forty Wistar male rats were divided into five groups: dPBS (sham-operated control), dAβ (Aβ control), JPBS (F8 and PBS), JAβ (F8 and Aβ), and IBFAβ (ibuprofen and Aβ). F8 (5 ml/kg BW), and ibuprofen (10 ml/kg BW) was given orally daily for four weeks before the intracerebroventricular infusion of Aβ for two weeks. Histological analysis and neuronal count of hippocampus tissue in the Cornu Ammonis (CA1) region showed that supplementation with F8 was able to prevent Aβ-induced tissue damage and neuronal shrinkage. However, no significant difference in locomotor activity and novel object recognition (NOR) percentage was detected among different groups at day 7 and day 14 following Aβ infusion. Only effect of time differences (main effect of day) was observed at day 7 as compared to day 14, where reduction in locomotor activity and NOR percentage was observed in all groups, with F (1, 7) = 6.940, p<0.05 and F (1, 7) = 7.152, p<0.05, respectively. Besides, the MDA level of the JAβ group was significantly lower (p<0.01) than that of the dPBS group. However, no significant changes in SOD activity were detected among different groups. Significant reduction in plasma CRH level (p<0.05) and iNOS expression (p<0.01) in the brain was detected in the JAβ group as compared to the dAβ group. Hence, our current findings suggest that the tropical fruit juice mixture (F8) has the potential to protect the rats from Aβ-induced neurotoxicity in brain hippocampus tissue possibly via its antioxidant properties and the suppression of iNOS expression and CRH production.

Soursop (Annona muricata L.) is a genus of tropical fruit trees belonging to the family Annonaceae, which is grown in Viet Nam. Soursop is highly nutritious but has economically low value and easily perishable. Therefore, this study aims to evaluate the effects of drying temperature (50oC, 60oC, 70oC, 80oC, 90oC) onphenolic compounds, antioxidant activities via reducing power and DPPH radical scavenging activity and sensory evaluation of soursop. The results showed that the total polyphenols content at the temperatures was 22.867 mg GAE per 100g dry matter; 23.450 mg GAE / 100g dry matter; 24.342 mg GAE / 100g dry matter; 27.747 mg GAE / 100g dry matter; 25.933 mg GAE / 100g dry matter. The samples at 60oC were found maximum in antioxidant activities which reduced as the heating drying temperature increased. Sensory evaluation showed that astringency taste was rated higher to the samples dried at 70oC with 150 minutes.

Medicinal Properties

Durio zibethinus, commonly known as Durian, is an exotic Southeast Asian tropical fruit. More than the pungent aroma the fruit is well-known for, it is said to be beneficial to health as it contains many antioxidants and bioactive compounds that have different potentials for positive impacts on health. However, there is scant existing literature which gives an overview on the amounts of bioactive compounds in several varieties of durian in Southeast Asia, and the relevant health benefits. This review article therefore seeks to consolidate the literature which have identified bioactive compounds and investigated antioxidant activities in durian cultivars from Malaysia, Indonesia, Thailand and China, and studies that have given insight on potential medicinal properties of durians. A literature review was conducted using databases Scopus and ScienceDirect and a total of 30 articles were reviewed. Total polyphenols and flavonoids were highest in the Mon Thong cultivar compared to other Thailand varieties, and ripe or overripe durians were found to contain the highest amounts of polyphenols and flavonoids. Durians were also found to contain medicinal properties, such as anti-inflammatory and antidiabetic potential, and protective effects on cardiac health. Further research on these bioactive compounds in the nutritious fruit with potential medicinal properties can contribute to the medicinal value of durians, as well as benefit the pharmaceutical industries.
