“…In the present study, the methanolic peel extract of Sindhura had better activity than the other extracts. These results are in accordance with the results of few researchers who measured ABTS activity on peel extracts of mango (40,41). H 2 O 2 is not very reactive; sometimes it can be toxic due to the increase in hydroxyl radicals in the cells (44).…”

“…In the present study, the methanolic peel extract of Sindhura cultivar gave better anti-oxidant activity than the other cultivar extracts. These results are similar to the reports of few researchers who studied the DPPH activity on peel extracts of mango (40,41). ABTS is a general assay to determine the anti-oxidant capacity in food products (42).…”

Introduction: All parts of the mango plant contain secondary metabolites that possess several beneficial properties. In the present study, evaluation of in vitro anti-oxidant, anti-microbial and anti-inflammatory activities of five Indian cultivars of mango fruit peel extracts were carried out.Methods: Different solvent (hexane, ethyl acetate, and methanol) extracts of five Indian cultivars of mango fruit peels were prepared by using soxhalate, and the aqueous extract was prepared by maceration. In vitro anti-oxidant activities of these extracts were determined by using 2,2-Diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azinobis 3-ethylbenzothiazoline-6-sulfonic acid (ABTS), hydrogen peroxide (H2O2) and nitric oxide (NO) radical scavenging methods. Their anti-microbial and anti-inflammatory activities were determined by agar-well diffusion and HRBC (human red blood cell) methods, respectively.Results: All the five mango peel extracts showed good anti-oxidant activities, especially the methanolic extract of peel of Sindhura cultivar showed better IC50 values of DPPH (21.62±1.82 μg/mL), ABTS (21.33±1.94 μg/mL), H2O2 (19.87±2.61 μg/mL) and NO (57.29±2.17 μg/mL) radical scavenging activities than other extracts. It also possessed higher contents of phenolics (169.18±3.28 mg of GAE/g) and flavonoids (26.18±1.84 mg of QE/g) than the other extracts. All peel extracts of five cultivars of mango fruit revealed good anti-microbial activities against bacterial and fungal cultures and also possessed significant anti-inflammatory activity.Conclusion: The present study revealed that all the mango peel extracts have potential antioxidant activity, as well as better anti-microbial and anti-inflammatory activities.

“…PCA is a linear dimensionality reduction approach. It can convert multidimensional data into a linearly independent variables matrix and the variables are arranged according to the contribution rates (called principal components (PCs)) [41,42]. Generally, the first two (PC1 and PC2) or three (PC1, PC2, and PC3) columns of data could explain most of the variables.…”

Aroma and taste are the most important attributes of alcoholic beverages. In the study, the self-developed electronic tongue (e-tongue) and electronic nose (e-nose) were used for evaluating the marked ages of rice wines. Six types of feature data sets (e-tongue data set, e-nose data set, direct-fusion data set, weighted-fusion data set, optimized direct-fusion data set, and optimized weighted-fusion data set) were used for identifying rice wines with different wine ages. Pearson coefficient analysis and variance inflation factor (VIF) analysis were used to optimize the fusion matrixes by removing the multicollinear information. Two types of discrimination methods (principal component analysis (PCA) and locality preserving projections (LPP)) were used for classifying rice wines, and LPP performed better than PCA in the discrimination work. The best result was obtained by LPP based on the weighted-fusion data set, and all the samples could be classified clearly in the LPP plot. Therefore, the weighted-fusion data were used as independent variables of partial least squares regression, extreme learning machine, and support vector machines (LIBSVM) for evaluating wine ages, respectively. All the methods performed well with good prediction results, and LIBSVM presented the best correlation coefficient (R2 ≥ 0.9998).

Tropical fruits represent one of the most important crops in the world. The continuously growing global market for the main tropical fruits is currently estimated at 84 million tons, of which approximately half is lost or wasted throughout the whole processing chain. Developing novel processes for the conversion of these byproducts into value‐added products could provide a viable way to manage this waste problem, aiming at the same time to create a sustainable economic growth within a bio‐economy perspective. Given the ever‐increasing concern about sustainability, complete valorization through a bio‐refinery approach, that is, zero waste concept, as well as the use of green techniques is therefore of utmost importance. This paper aims to report the status on the valorization of tropical fruit byproducts within a bio‐refinery frame, via the application of traditional methodologies, and with specific attention to the extraction of phenolics and carotenoids as bioactive compounds. The different types of byproducts, and their content of bioactives is reviewed, with a special emphasis on the lesser‐known tropical fruits. Moreover, the bioactivity of the different types of extracts and their possible application as a resource for different sectors (food, pharmaceutical, and environmental sciences) is discussed. Consequently, this review presents the concepts of tropical fruit biorefineries, and the potential applications of the isolated fractions.
