[Ab] Resumo:The waste mango seed generated from mango pulp industry in India is a major problem in handling the waste and hence, conversion of mango seed kernel. Mango seeds were collected and processed for oil extraction. Decolorization of methylene blue was achieved by mango seed kernel powder, mango leaf powder and Manilkara zapota seed powder. Higher efficiency was attained in mango seed kernel powder when compared to mango leaf powder and Manilkara zapota seed powder. A 60 to 95 % of removal efficiency was achieved by varying concentration. Effect of pH, dye concentration, adsorbent dosage and temperature were studied. Mango seed kernel powder is a better option that can be used as an adsorbent for the removal of methylene blue and basic red dye from its aqueous solutions.

[Ab] Resumo:Weather factors play an important role in occurrence of thrips on mango. Keeping this in view, the present investigation was set out to assess the thrips population dynamics using humid thermal index, based on data sets from 22 fixed plot mango orchards in and around Lucknow. Results revealed that the highest thrips population of 3.36/panicle was recorded in Kakori (Fixed plot -I) orchard, which was followed by 2.4 and 2.06 at CISH III block and Kanar (Fixed II) respectively during the year 2013, whereas corresponding values were 4.05, 3.08 and 2.50 at CISH Block III, CISH Bolck II and Allupur respectively during 2014. The frequency distribution explained that the thrips population of <2 /panicle was widely distributed with highest frequency level. The humid thermal ratio ranged from 1.44 to 2.27 and 1.20 to 2.34 during 2013 and 2014 respectively across standard meteorological weeks. The peak thrips incidence was 6.18 /panicle during 2013 and 4.67/panicle during 2014, the corresponding values of humid thermal ratio were 1.47 and 2.05 respectively. The positive correlation was found between humid thermal ratio and thrips population dynamics during 2013 (r = 0.52**) and 2014 (r = 0.72**). Pooled data showed significant and positive correlation between humid thermal ratio and thrips population. Pooled analysis had explained up to 94 per cent of variation with exponential model (Thrips population = 0.007e2.778HTR, R2 = 0.94**) and suggested that this index might be used in understanding the mango thrips population dynamics under subtropical environmental condition.

[Ab] Resumo:The current review article is an attempt to explain the therapeutic potential of mangiferin, a bioactive compound of the mango, against lifestyle-related disorders. Mangiferin (2-ß-D-glucopyranosyl-1,3,6,7-tetrahydroxy-9H-xanthen-9-one) can be isolated from higher plants as well as the mango fruit and their byproducts (i.e. peel, seed, and kernel). It possesses several health endorsing properties such as antioxidant, antimicrobial, antidiabetic, antiallergic, anticancer, hypocholesterolemic, and immunomodulatory. It suppresses the activation of peroxisome proliferator activated receptor isoforms by changing the transcription process. Mangiferin protects against different human cancers, including lung, colon, breast, and neuronal cancers, through the suppression of tumor necrosis factor α expression, inducible nitric oxide synthase potential, and proliferation and induction of apoptosis. It also protects against neural and breast cancers by suppressing the expression of matrix metalloproteinase (MMP)-9 and MMP-7 and inhibiting enzymatic activity, metastatic potential, and activation of the ß-catenin pathway. It has the capacity to block lipid peroxidation, in order to provide a shielding effect against physiological threats. Additionally, mangiferin enhances the capacity of the monocyte-macrophage system and possesses antibacterial activity against gram-positive and gram-negative bacteria. This review summarizes the literature pertaining to mangiferin and its associated health claims.

[Ab] Resumo:BACKGROUND: Soy milk-based beverages play an important role as a healthy food alternative for human consumption. However, the ‘beany’ flavor and chalky mouth feel of soy milk often makes it unpalatable to consumers. The objective of the present study is to optimize a blend of soy milk, mango nectar and sucrose solution for the best quality soy milk-based beverage. METHODS: This study was designed to develop a soy milk blended beverage, with mango nectar and sucrose solutions, with the best physicochemical and sensory properties. Fourteen combinations of formulations were determined by D-optimal mixture simplex lattice design, by using Design expert. The blended beverages were prepared by mixing the three basic ingredients with the range of 60−100% soy milk, 0–25% mango nectar and 0–15% sucrose solution. The prepared blended beverage was analyzed for selected physicochemical and sensory properties. The statistical significance of the terms in the regression equations were examined by Analysis of Variance (ANOVA) for each response and the significance test level was set at 5% (p < 0.05). RESULTS: The results showed that, as the proportion of mango nectar and sucrose solution increased, total color change, total soluble solid, gross energy, titratable acidity, and beta-carotene contents increased but with a decrease in moisture , ash, protein, ether extract, minerals and phytic acid contents was observed. Fi- nally, numerical optimization determined that 81% soy milk, 16% Mango nectar and 3% sugar solution will give by a soy milk blended beverage with the best physicochemical and sensory properties, with a desirability of 0.564. CONCLUSIONS: Blending soy milk with fruit juice such as mango is beneficial, as it improves sensory as well as selected nutritional parameters.

[Ab] Resumo:Aroma is important in assessing the quality of fresh fruit and their processed products, and could provide good indicators for the development of local cultivars in the mango industry. In this study, the volatile diversity of 25 mango cultivars from China, America, Thailand, India, Cuba, Indonesia, and the Philippines was investigated. The volatile compositions, their relative contents, and the intervarietal differences were detected with headspace solid phase microextraction tandem gas chromatography-mass spectrometer methods. The similarities were also evaluated with a cluster analysis and correlation analysis of the volatiles. The differences in mango volatiles in different districts are also discussed. Our results show significant differences in the volatile compositions and their relative contents among the individual cultivars and regions. In total, 127 volatiles were found in all the cultivars, belonging to various chemical classes. The highest and lowest qualitative abundances of volatiles were detected in 'Zihua' and 'Mallika' cultivars, respectively. Based on the cumulative occurrence of members of the classes of volatiles, the cultivars were grouped into monoterpenes (16 cultivars), proportion and balanced (eight cultivars), and nonterpene groups (one cultivars). Terpene hydrocarbons were the major volatiles in these cultivars, with terpinolene, 3-carene, caryophyllene and α-Pinene the dominant components depending on the cultivars. Monoterpenes, some of the primary volatile components, were the most abundant aroma compounds, whereas aldehydes were the least abundant in the mango pulp. ß-Myrcene, a major terpene, accounted for 58.93% of the total flavor volatile compounds in 'Xiaofei' (Philippens). γ-Octanoic lactone was the only ester in the total flavor volatile compounds, with its highest concentration in 'Guiya' (China). Hexamethyl cyclotrisiloxane was the most abundant volatile compound in 'Magovar' (India), accounting for 46.66% of the total flavor volatiles. A typical aldehydic aroma 2,6-di-tert-butyl-4-sec-butylphenol, was detected in 'Gleck'. A highly significant positive correlation was detected between Alc and K, Alk and Nt, O and L. Cultivars originating from America, Thailand, Cuba, India, Indonesia and the Philippines were more similar to each other than to those from China. This study provides a high-value dataset for use in development of health care products, diversified mango breeding, and local extension of mango cultivars.

[Ab] Resumo:In mango, fruitlet abscission initiates with a decrease in polar auxin transport through the abscission zone (AZ), triggered by ethylene. To explore the molecular components affecting this process, we initially conducted experiments with developing fruitlet explants in which fruitlet drop was induced by ethephon, and monitored the expression patterns of distinct indole-3-acetic acid (IAA)-related genes, comparing control vs. ethephon-treated pericarp and AZ profiles. Over the examined time period (48 h), the accumulation of MiPIN1 and MiLAX2 IAA-efflux and influx genes decreased in both control and treated tissues. Nevertheless, ethephon-treated tissues displayed significantly lower levels of these transcripts within 18-24 h. An opposite pattern was observed for MiLAX3, which overall exhibited up-regulation in treated fruitlet tissues. Ethephon treatment also induced an early and pronounced down-regulation of five out of six IAA-responsive genes, and a substantial reduction in the accumulation of two IAA-synthesis related transcripts, contrasting with significant up-regulation of Gretchen Hagen3 transcript (MiGH3.1) encoding an IAA-amino synthetase. Furthermore, for both control and treated AZ, the decrease in IAA-carrier transcripts was associated with a decrease in IAA content and an increase in IAA-Asp:IAA ratio, suggesting that fruitlet drop is accompanied by formation of this non-hydrolyzed IAA-amino acid conjugate. Despite these similarities, ethephon-treated AZ displayed a sharper decrease in IAA content and higher IAA-Asp:IAA ratio within 18 h. Lastly, the response of IAA-related genes to exogenous IAA treatment was also examined. Our results are discussed, highlighting the roles that distinct IAA-related genes might assume during mango fruitlet drop.

[Ti] Título:Fluorophore ligand binding and complex stabilization of the RNA Mango and RNA Spinach aptamers.
[So] Source:RNA;22(12):1884-1892, 2016 12.

[La] Idioma:eng
[Ab] Resumo:The effective tracking and purification of biological RNAs and RNA protein complexes is currently challenging. One promising strategy to simultaneously address both of these problems is to develop high-affinity RNA aptamers against taggable small molecule fluorophores. RNA Mango is a 39-nucleotide, parallel-stranded G-quadruplex RNA aptamer motif that binds with nanomolar affinity to a set of thiazole orange (TO1) derivatives while simultaneously inducing a 10 -fold increase in fluorescence. We find that RNA Mango has a large increase in its thermal stability upon the addition of its TO1-Biotin ligand. Consistent with this thermal stabilization, RNA Mango can effectively discriminate TO1-Biotin from a broad range of small molecule fluorophores. In contrast, RNA Spinach, which is known to have a substantially more rigid G-quadruplex structure, was found to bind to this set of fluorophores, often with higher affinity than to its native ligand, 3,5-difluoro-4-hydroxybenzylidene imidazolinone (DFHBI), and did not exhibit thermal stabilization in the presence of the TO1-Biotin fluorophore. Our data suggest that RNA Mango is likely to use a concerted ligand-binding mechanism that allows it to simultaneously bind and recognize its TO1-Biotin ligand, whereas RNA Spinach appears to lack such a mechanism. The high binding affinity and fluorescent efficiency of RNA Mango provides a compelling alternative to RNA Spinach as an RNA reporter system and paves the way for the future development of small fluorophore RNA reporter systems.

[Ab] Resumo:Two fresh (fresh cubic pieces, fresh puree) and two dried (dried cubic pieces, dried powder) products were prepared from a homogenous mango fruit batch to obtain four samples differing in texture. The aromatic profiles were determined by SAFE extraction technique and GC-MS analysis. VOCs released during consumption were trapped by a retronasal aroma-trapping device (RATD) and analysed by GC-MS. Twenty-one terpenes and one ester were identified from the exhaled nose-space. They were amongst the major mango volatile compounds, 10 of which were already reported as being potential key flavour compounds in mango. The in vivo release of aroma compounds was affected by the matrix texture. The intact samples (fresh and dried cubic pieces) released significantly more aroma compounds than disintegrated samples (fresh puree, dried powder). The sensory descriptive analysis findings were in close agreement with the in vivo aroma release data regarding fresh products, in contrast to the dried products.

[Ab] Resumo:Mango is a highly perishable fruit with a short post-harvest time due to the intense metabolic activity after harvesting. In attempt to evaluate the effects of chitosan in mango fruits, it was treated with 0%, 1%, 2% or 3% of chitosan solutions, placed into plastic trays, and stored at room temperature. Changes in physical and chemical parameters were evaluated. Chitosan delayed the climacteric peak, water loss and firmness. Further, few changes in soluble solid content, titratable acidity, pH of the pulp as well as in sugar content and decreased starch degradation were observed. Altogether, our results suggest chitosan edible coating effectively prolongs the quality attributes, affecting basic mitochondrial respiration and starch degradation rate.

[Ab] Resumo:Due the negative effects of pesticides on environment and human health, more efficient and environmentally friendly methods are needed. In this sense, a simple, fast, free from memory effects and economical direct-immersion single drop micro-extraction (SDME) method and GC-MS for multi-class pesticides determination in mango samples was developed. Sample pre-treatment using ultrasound-assisted solvent extraction and factors affecting the SDME procedure (extractant solvent, drop volume, stirring rate, ionic strength, time, pH and temperature) were optimized using factorial experimental design. This method presented high sensitive (LOD: 0.14-169.20µgkg ), acceptable precision (RSD: 0.7-19.1%), satisfactory recovery (69-119%) and high enrichment factors (20-722). Several obtained LOQs are below the MRLs established by the European Commission; therefore, the method could be applied for pesticides determination in routing analysis and custom laboratories. Moreover, this method has shown to be suitable for determination of some of the studied pesticides in lime, melon, papaya, banana, tomato, and lettuce.
