“…However, there is little scientific evidence regarding the benefits of star fruit juice intake by elderly subjects. Therefore, the results of this preliminary study possibly support the results of previous one,20 especially with regard to oxidative stress and lipid profiles. Although the protocol design of this study did not include a formal control group, our data are appropriate for such a preliminary investigation.…”

“…The previous study of star fruit juice consumption showed positive benefits with regard to proinflammatory and functional capacity in elderly individuals 20. Moreover, the benefits of star fruit juice consumption with regard to anti-inflammatory, analgesic, hypoglycemic, anthelmintic, antiulcer, hypotensive, antimicrobial, and antioxidant pharmacological activities have been reported 14.…”

“…Moreover, some reports suggested that HDL can inhibit the inflammatory process by several mechanisms, including promotion of cholesterol efflux, inhibition of LDL oxidation, and reduction of adhesion molecule expression 34,35. Increased HDL in the elderly after they consumed star fruit juice possibly helps to explain why the previous preliminary study found significantly reduced proinflammatory cytokines such as tumor necrosis factor-α and interleukin-23 20. Furthermore, the results of antioxidant status in the blood of elderly subjects can be used to explain why a significant reduction in NO level was observed in this study and the previous study.…”

“…The sample size was calculated by a G*Power (3.1.9.2) program with an effect size =0.92, alpha error =0.05, and power =0.95 from the previous study 20. A minimum of 24 elderly subjects were required for this study.…”

“…However, star fruit is not popular and not consumed in as much quantity as other fruits such as water melon, banana, guava, and orange. Moreover, Leelarungrayub et al updated their preliminary study on supplementation of star fruit juice twice daily for 1 month to elderly subjects and showed significant inhibition of release of proinflammatory cytokines such as tumor necrosis factor-α and interleukin-23, as well as an increase in walking distance 20. However, prior work did not investigate the active compounds in the star fruit, nor did the work determine the impact of the star fruit on the lipid profile in elderly subjects.…”

ObjectiveThe aims of this preliminary study were to evaluate the antioxidant and lipid status before and after star fruit juice consumption in healthy elderly subjects, and the vitamins in star fruit extracts.MethodsA preliminary designated protocol was performed in 27 elderly individuals with a mean (±SD) age of 69.5±5.3 years, by planning a 2-week control period before 4 weeks of consumption of star fruit twice daily. Oxidative stress parameters such as total antioxidant capacity, glutathione, malondialdehyde, protein hydroperoxide, multivitamins such as l-ascorbic acid (Vit C), retinoic acid (Vit A), and tocopherol (Vit E), and the lipid profile parameters such as cholesterol, triglyceride, high-density lipoprotein-cholesterol (HDL-C) and low-density lipoprotein-cholesterol (LDL-C) were analyzed. Moreover, Vit C, Vit A, and Vit E levels were evaluated in the star fruit extracts during the 4-week period.ResultsIn the 2-week control period, all parameters showed no statistically significant difference; after 4 weeks of consumption, significant improvement in the antioxidant status was observed with increased total antioxidant capacity and reduced malondialdehyde and protein hydroperoxide levels, as well as significantly increased levels of Vit C and Vit A, when compared to the two-time evaluation during the baseline periods. However, glutathione and Vit E showed no statistical difference. In addition, the HDL-C level was higher and the LDL-C level was significantly lower when compared to both baseline periods. But the levels of triglyceride and cholesterol showed no difference. Vit C and Vit A were identified in small quantities in the star fruit extract.ConclusionThis preliminary study suggested that consumption of star fruit juice twice daily for 1 month improved the elderly people’s antioxidant status and vitamins, as well as improved the lipoproteins related to Vit C and Vit A in the star fruit extract.

Correlating the natural color of tropical fruit juice with its pH

Color analysis is a critical approach used to analyze the quality properties of fruits, particularly in tracing the ripening stage through the peel color of the fruits. In this study, the color features of natural and untreated tropical fruit juice images (ie, B10 Averrhoa carambola L. and Sala mango) were correlated with the pH of the juice samples. The CIELAB color characteristics of the fruits showed that the mango juice had darker features than the carambola juice. The cause may be due to the higher soluble solid content and denser yellow and red pigments in the mango juice. For carambola juice, multiple linear regression (MLR) performed on red‐blue (RB) components generated the best prediction of pH with the highest coefficient of determination and lowest root mean square of error. For mango juice, MLR performed on normalized red‐green‐blue (RGB) components generated the best prediction of pH.

Star fruit (Averrhoa carambola), a popular fruit in many parts of the world, is considered to have many beneficial nutritional and medicinal effects. However, harmful nephrotoxic and neurotoxic effects have also been described. In this review, we have discussed the reported beneficial effects of star fruit, explored the potential mechanisms for such beneficial effects, and outline factors that may affect the safe level of consumption. The beneficial effects include the following: antioxidant (mediated via L‐ascorbic acid, epicatechin, and gallic acid), hypoglycemic (mediated via high fiber levels and 2‐dodecyl‐6‐methoxycyclohexa‐2,5‐diene‐1,4‐dione), hypotensive (mediated via apigenin), hypocholesterolemic (mediated via micronized fiber), anti‐inflammatory, anti‐infective, antitumor effects, and immune‐boosting effects. The presence of chronic kidney disease, gastroenteropathies, chronic pancreatitis, dehydration, consumption on an empty stomach, and higher concentration of oxalate in fruit/juice consumed predisposes to toxicity. The level of ingestion at which the beneficial effects transition to nephrotoxicity and neurotoxicity is still to be accurately ascertained. Furthermore, the relationship between the amount of star fruit ingested and the severity of toxicity is not certain and warrants further study.
