为给芒果加工副产物综合利用提供理论依据,以芒果核为原料,研究桂七、贵妃、台农、金煌芒、玉芒和象牙芒六个品种中的多酚和黄酮含量及其抗氧化活性的影响。结果显示,玉芒芒果核多酚和黄酮含量最高,分别为4.31和1.07 mg/g,金煌芒、台农、桂七、象牙芒、贵妃芒果核中的多酚含量分别为4.20、4.10、3.96、3.86、3.82 mg/g,其黄酮含量分别为0.95、0.88、0.92、0.96、0.75 mg/g;抗氧化活性研究结果发现,玉芒芒果核羟基自由基(·OH)清除率、超氧阴离子自由基清除率最强,为90.1%和83.9%。通过相关性分析发现,多酚和黄酮含量分别与羟基自由基清除率、超氧阴离子自由基清除率显著相关(P<0.05),不同品种芒果核中多酚、黄酮含量高低与其抗氧化活性呈正效应的量效关系,且黄酮对芒果核抗氧化能力影响较大,其含量的变化有可能是导致不同品种芒果核抗氧化能力差异的重要因素。 相似文献

以质构品质为评价指标,研究了不同芒果品种、成熟度、硬化剂、硬化剂浓度、硬化时间、果粒大小对芒果果粒硬化效果的影响,并通过正交实验确定芒果果粒加工工艺优化参数。结果表明:台农芒果粒的硬度、咀嚼性显著高于贵妃芒、玉芒,弹性显著高于贵妃芒、玉芒、金煌芒。青熟、完熟芒果果粒硬度显著高于过熟芒果。乳酸钙处理组的芒果果粒硬度显著高于氯化钙、海藻酸钠处理组。正交实验结果表明,以完熟台农芒为原料,以乳酸钙为硬化剂,影响果粒硬度的主要因素是果粒大小与硬化剂浓度,适宜芒果果粒加工的优化工艺为:果粒大小为1.5 cm×1.5 cm×1.5 cm,硬化剂浓度为0.04 g/mL,硬化时间为2 h。在该条件下,芒果果粒的硬度为525.17 g。 相似文献

为表征台农、象牙和金煌三种芒果的品质特性,本文通过测定其主要品质指标,利用主成分分析法(PCA),构建芒果主要品质综合评分模型,并采用HS-SPME-GC-MS技术对其挥发性风味物质进行分析,综合评价其品质。结果表明,金煌的可溶性固形物、总糖含量和糖酸比最高,分别为19%、24.18 mg/g和10.86;台农的VC和总酚含量最高,分别达9.52 mg/100 g和1.03 mg/g;主成分分析结果表明,台农的综合得分最高,其次为金煌,象牙的综合得分最低。HS-SPME-GC-MS技术从三种芒果中共检测出116种挥发性风味物质,主要包括烯烃类、酚类和醛类等8类物质。台农和象牙的挥发性化合物以烯烃类为主,相对含量分别为45.52%和58.12%,金煌中以酚类物质为主,相对含量为56.88%。通过ROAV分析法共确定了15种关键风味化合物,其中台农和象牙香气贡献最大的物质为(E,Z)-2,6-壬二烯醛,金煌香气贡献最大的是3-己烯醛。台农呈柑橘香、甜香等芳香气味,象牙具有黄瓜香特征风味,而金煌含有特殊的木香气味,该风味主要由2,4-二叔丁基苯酚所贡献。综合分析认为,台... 相似文献

Mango is one of the most important tropical fruits and India ranks first in its world production. During the processing of mango, mainly for mango pulp and preparation of amchur powder, peel is a by-product. Peel forms about 20% of the whole fruit and at present it is a waste product and its disposal has become a great problem. With a view to exploit mango peel as a source of valuable components, in the present study, proximate composition, polyphenols, carotenoids, dietary fibre contents and activities of few enzymes in raw and ripe peels of two Indian mango varieties, namely, Raspuri and Badami were determined. The polyphenol contents in these peels ranged from 55 to 110 mg/g dry peel. Dietary fibre content ranged from 45% to 78% of peel and was found at a higher level in ripe peels. Similarly, carotenoid content was higher in ripe fruit peels. Vitamins C and E contents ranged from 188 to 392 and 205 to 509 μg/g dry peel, respectively; and these were found at a higher level in ripe peels. Both raw and ripe mango peels exhibited significant amount of protease, peroxidase, polyphenol oxidase, xylanase and amylase activities. 相似文献

Volatile Components of African Mango 总被引:1,自引:0,他引:1
Volatile components of African mango were isolated by vacuum distillation and fractionation on silica gel or by trapping on Tenax GC. Analysis by combined GC-MS led to several compounds identified for the first time. Presence in the extract of isolongifolene, eremophilene (17%), and components related to bicyclogermacrene showed the variability of the volatile fraction of mango varieties. Some of these compounds, as well as A-3 carene, may be typical of local varieties. The African mango studied is also characterized by presence of free acids: acetic (0.7%), butyric (6%) and hexanoic (5%); and ethyl 3-hydroxybutyrate (5%). These compounds are part of the contribution of lipid metabolism to aroma of mango fruit. 相似文献

以“象牙”和“台农”芒果为试材,研究BTH 处理对2 个不同品种芒果果实中主要防御酶—— PAL、PPO 和POD 活性的影响,以探讨其增强不同果实抗病性的机理。结果表明:在整个贮藏过程中,“台农”果实本身3 种酶的活性均明显高于“象牙”果实;而经BTH 处理后,对2 个品种的芒果果实,均刺激了3 种酶活性的上升,并且“台农”果实上升幅度明显高于“象牙”果实。BTH 处理增强果实抗病性与刺激PAL、PPO 和POD 活性上升均有关系,并且对台农果实作用明显大于象牙果实。 相似文献

Fermentation of three varieties of mango juices with a mixture of Saccharomyces cerevisiae and Williopsis saturnus var. mrakii 总被引:1,自引:0,他引:1
This study was carried out to ascertain the behavior and fermentation performance of mixed yeasts in mango juices of three varieties. Saccharomyces cerevisiae MERIT.ferm and Williopsis saturnus var. mrakii NCYC500 at a ratio of 1:1000 were simultaneously inoculated into juices of three mango (Mangifera indica L.) varieties (R2E2, Harum Manis and Nam Doc Mai). Both yeasts grew well in all juices and there was no early growth arrest of either yeast, but there was late death of W. saturnus var. mrakii NCYC500 in the Nam Doc Mai juice. Fructose, glucose and sucrose were consumed to trace levels in all juices. Changes in citric, tartaric, malic, acetic and succinic acids varied with mango varieties. While the changes of major volatiles were similar in all varieties, there were significant varietal differences in the volatile composition of the resultant mango wines. The volatiles, especially most of the terpenes, of the juices decreased drastically and new volatiles such as β-citronellol were formed. R2E2 wine had more fruity, sweet and creamy notes, and retained more of its original character due to a higher retention of ketones/lactones. Harum Manis wine had the lowest aroma intensity with more green and terpenic notes associated with higher levels of residual terpenes than the other two varieties. Nam Doc Mai wine possessed the highest aroma intensity with winey, yeasty, fruity and floral notes attributed to higher amounts of alcohols, acetate esters and ethyl esters. These findings may help develop different styles of mango wine. 相似文献

探讨不同加工处理对芒果果浆在贮藏过程中抗氧化成分和抗氧化能力的影响规律,以期为芒果果浆的贮藏提供指导。对芒果果浆分别进行超高压(600MPa,1min)、高温短时(110℃,10s)和低温长时处理(70℃,30min),分析不同加工处理后芒果果浆在贮藏过程(015W)中抗氧化成分(L-抗坏血酸、总酚和总类胡萝卜素)和抗氧化能力(采用DPPH和FRAP法评价)变化。结果表明:不同加工处理对芒果果浆在贮藏过程中其抗氧化成分和清除DPPH·能力有显著影响,其中超高压处理能够较好的保持芒果果浆的总酚和总类胡萝卜素含量以及样品清除DPPH·能力;用零级、一级和零级、一级联合动力学模型拟合各抗氧化成分指标的动态变化的研究发现,联合动力学模型可以更好地表示L-抗坏血酸、总酚和总类胡萝卜素的动态变化(R>0.988)。本研究对不同加工处理后芒果果浆在贮藏过程中抗氧化成分和抗氧化能力变化进行了分析,现有的分析将为超高压技术应用于工业化生产芒果果浆中贮藏性、稳定性和质量评价提供数据支撑。 相似文献
