Changes in Mango Fruit Characteristics during Development and after Harvest
No full textThe physical and biochemical changes during mango fruit development and after harvest were studied. ‘Irwin' and ‘chai' mango (Mangifera indica L.) fruit were harvested at 62, 76, 90, 104, 118 and 132 days after full bloom (DAFB). The level of sucrose in flesh increased rapidly from 104 to 132 DAFB. Reducing sugars, comprising mainly of fructose, slightly decreased during fruit ripening. The amount of starch slightly decrease at the same period. α-Amylase activity increased parallel to the increase in fruit weight and rapidly decrease 104 DAFB. The protein content rapidly increased at the onset of ripening 104 DAFB. Fruit harvested at the 118 DAFB were used for postharvest observation. Sucrose was the predominant sugar during fruit ripening postharvest. The level of sucrose increased 4 days after harvest and then remained high. Reducing sugars, comprising mainly of fructose, and the amount of starch decreased slightly during ripening. α-Amylase activity decreased markedly 4 days after harvest. Protein content increased rapidly 2 days after harvest.本研究調查芒果果實發育期間及採收後物理的及生化的變化。分別於滿花後62、76、90、104、118及132天採收”愛文”及”紫樣”芒果果實，結果發現：果肉內蔗糖含量於滿花後第104天至132天快速增加，而果糖含量在果實成熟期間稍微下降，同期間，果肉內澱粉含量亦稍微下降。α-Amylase活性隨著果重的增加而上升，但在滿花後104天之後迅速下降。另於滿花後第118天採收果實，觀察其採收後後熟之變化。芒果果肉採後後熟期間主要的醣類為蔗糖，其含量於採收後第4天開始增加，此後則維持高含量。澱粉含量在同一期間些微下降，採收後4天α-澱粉水解酵素活性明顯下降，而蛋白質含量在採收後2天快速增加
ESPERANZA’S PERSONALITY DEVELOPMENT AS REFLECTED IN SANDRA CISNEROS’ THE HOUSE ON MANGO STREET
No full textThis study discusses The House on Mango Street, a novel written by
Sandra Cisneros. This novel presents a main character named Esperanza who
experiences personality development. This study is meant to answer three
problems concerning the main character’s personality development. The first
problem is Esperanza’s basic personality in the novel. The second problem is
Esperanza’s personality development. The third problem is the influencing factors
toward Esperanza’s personality development.
This study is a qualitative study applying content analysis method. This
study applies the theory of personality and personality development emphasizing
on Hurlock’s theory on personality development. The object of this study is
Sandra Cisneros’ The House on Mango Street. The data collected are lines related
to the topic under study found in the novel. The data analysis was conducted by
analyzing the required lines found in The House on Mango Street in accordance
with the theory. In achieving reliability, the researcher read and reread the novel
comprehensively, then recorded the data. The triangulation method was applied to
gain the trustworthiness of the data through consulting the finding with first and
second consultant.
The result of this study shows that Esperanza’s personality develops.
There are two significant factors that influence Esperanza’s personality
development. The first is the early experiences within family. The second is the
important events outside home. Early experience within family gives influence
toward Esperanza through supportive parents and family’s financial difficulty,
while important events outside home also gives influence toward Esperanza’s
personality mostly through the peers and neighborhood. From the analysis on the
factors that influence Esperanza’s personality, the researcher finds that Esperanza
is unconfident, pessimistic, and naïve at the beginning of the story, and then she
turns into a confident, optimistic, and sophisticated person at the end
Comparison of methods of extraction of antioxidant compounds from the peel from Mango (Manguifera indica L.)
No full textThere is considerable interest in characterising the antioxidant properties of many foods. Mango, (Mangifera indica L.) is a sub-tropical fruit of commercial importance. However, the skins are not normally eaten allthough they may contain nutritionally useful ingredients. We compared the efficiency of three different methods for extracting antioxidant compounds: methanol-acetone (MA), methanol-water (MW) and water (W) as solvents, for the extraction of phenolic compounds with antioxidant activity. The total phenolic content and the total antioxidant capacity (TAC) of the different extracts was measured by the oxygen radical absorbance capacity (ORAC) method. At the same time the influence of the pre-treatment drying methods freeze drying (F) and oven drying (O), were evaluated. The TAC of the extracts ranged from 4,539.0 to 11938.4 μM of Trolox equivalent (TE) per g of dry weight (DW), with the aqueous method (W) significantly the most effective. However, there was no statistical difference in the total phenolic content of the extracts. None of the drying methods had any significant effect on the total antioxidant capacity and the total phenolic content. The efficiency and simplicity of the aqueous extraction make it zan excellent method for the extraction of hydrophilic antioxidant compounds with important bioactive properties

Development of Kombucha Tea with Gac and Mango Fruits: Sensory, Nutritional, Phytochemical, Physicochemical and Antioxidant Evaluation
No full textKombucha tea is a sweetened black tea beverage that undergoes fermentation with a starter culture of bacteria and yeast (SCOBY). In this study, gac (Momordica cochinchinensis) and mango (Mangifera indica) fruits were primarily chosen for infusion into kombucha due to their health benefits. Thus, thisresearch aims to develop kombucha black tea with gac and mango, evaluate the sensory evaluation of the kombucha tea, and analyse the nutritional composition, physicochemical, phytochemical, and antioxidant activity of the kombucha tea. In this study, kombucha was prepared by fermenting black tea with sugar at different concentrations (70, 80, and 100 g) and SCOBY for 10 days before infusing it with gac and mango fruits. The sensory evaluation was
evaluated using a hedonic 9-scale and another while using the standard methods. The result showed that kombucha gac and mango fruit with100 g of sugar (KGM100) represents the highest score on all attributes with a value of colour 7.5±1.55, aroma 6.47±1.74, taste 6.6±1.77, and overall, of 6.6±1.77. The nutrient of KGM 100 was higher than other concentrations with a value content of carbohydrates 6.9% and vitamin C of 2.70 mg/kg. The phytochemical of all samples showed increment during fermentation time and the antioxidant activity is higher in KGM100 (95.88%) while the physicochemical properties showed an increase in acidity and a decrease in colour. These findings show that kombucha black tea with gac and mango may impact health when consume and future investigation is worthy to determine its potential health benefits
Detection of genetic diversity among Indian strains of _Xanthomonas campestris_ pv. _mangiferaeindicae_ using PCR-RAPD
No full textThe randomly amplified polymorphic DNA (RAPD) technique was used to investigate the genetic diversity in 6 strains of _Xanthomonas campestris_ pv. _mangiferaeindicae_ (_Xcmi_), the causal pathogen of mango bacterial canker disease (MBCD). The RAPD analysis was also intended to identify molecular markers, specific to the species to develop PCR-based markers for detection of _Xcmi_ in mango field and planting materials. Twenty RAPD primers (CP 1-CP 20) were evaluated to establish molecular characters and genetic variability in the genome of _Xcmi_. Among these, only 4 were found efficient for development of reproducible banding pattern. It has been observed that the largest and smallest amplified RAPD products were of 2.036 and 0.201 kbp. A total of 136 bands were scored against 6 strains of _Xcmi_. There was 7.66 per cent polymorphism in individual isolates which indicates significant polymorphism among the evaluated strains, with mean difference of 0.33 (_Xcmi_ 2 vs. _Xcmi_ 8) and 0.29 (_Xcmi_ 10 vs. _Xcmi_ 12). However, the single linkage euclidean distances were statistically significant (P>0.05), i.e., 0.58. The markers CP 5, 10, 16 and 19 were amplified in all the strains with polymorphic alleles, which indicates that these markers could be used for rapid detection of genetic variability in _Xcmi_ strains
A Study of the Developmental Process of Floral Bud of Mango (Mangifera indica L.)
No full textThree mango cultivars,‘Chai-She’、‘Irwin’and‘Sensation’were used for the determination of the morphological changes of floral buds during the period of differentiation.
Results indicated that the time of differentation was at the end of November and mid December in central Taiwan. External characteristics of floral bud were round and plump with bulging base. This is commonly used as an index of floral bud differentiation which leads to a series of changes beginning at early January in the following sequence; first the formation of sepal then the petal and the carpel tissue, the process was completed at the end of the same month.芒果三栽培種‘柴檨’(本地種)、‘愛文’、‘聖心’，利用切片觀察其花芽分化。結果顯示分化時間約在11月下旬至12月中旬，外表特徵為頂芽基部肥大，芽體外觀變圓而飽滿；內部解剖發現腋芽開始膨大，同時葉腋間有側芽形成時，此為芒果花芽分化的指標。花序上各花器在翌年1月上旬分化，萼片首先形成、次為花瓣及心皮分生組織而於1月下旬逐漸分化完成，花器分化後圓錐花序陸續抽長，而於翌年1月下旬至2月下旬開花

Set in Miami at the start of the twenty-first century, THE MANGO SNORES is a seriocomic crime novel chronicling a week in the life of Sam Espada, Cuban-American writing professor and author of the Mango series of detective fiction. Reeling from the sudden dissolution of his marriage and the abject failure of his latest book, Sam finds himself embroiled in a plot right out of one of his novels when his newest pupil, private investigator Leonard Cobb, is found stabbed through the eye with Sam’s fountain pen, leading homicide detective Vernon Harvey to peg Sam as the prime suspect. With no leads, no access to the crime scene, and nothing to go on but Cobb’s casebook, Sam and his neurotic sidekick, Max Plotkin, must unravel the plot that killed Leonard Cobb—before the plot unravels them
