Abstract

This study employs synchronous fluorescence spectroscopy to analyze the biochemical composition and quality of one of the most commercialized tropical fruit juice of mango. Commercially available juices in comparison with pure mango pulp from Anwar Ratol and white Chaunsa cultivars showed distinct bands oweing to the emission from tryptophan, phenolic compounds, riboflavin and chlorophyll, emphasizing the nutritional and phytochemical richness of mango pulp. Dilutions of pure mango pulp significantly decreased overall band intensities, indicating reduced nutritional content that can be marked in water adulterated samples. Similarly color adulteration resulted not only notable decrease in band intensity but deformed peaks in the range of 410-530 nm, Thermally treated mango pulp maintained molecular structure and fluorescence intensity till 80 ^oC, while higher temperatures may led to the breakdown of phenolic compounds and enhanced fluorescence emission. These findings highlight the effectiveness of synchronous fluorescence spectroscopy in assessing juice quality, optimizing processing conditions and ensuring product authenticity and consumer safety.

利用同步荧光光谱技术实时控制芒果汁的质量。

本研究采用同步荧光光谱法分析了一种最商业化的热带芒果果汁的生化成分和品质。由于色氨酸、酚类化合物、核黄素和叶绿素的释放，市面上可买到的芒果汁与Anwar Ratol和Chaunsa白色品种的芒果浆相比，呈现出明显的色氨酸带，强调了芒果浆营养和植物化学的丰富性。稀释的纯芒果果肉显著降低了整体波段强度，表明在掺水的样品中可以标记出营养含量的降低。同样，掺入颜色不仅导致波段强度明显降低，而且在410-530 nm范围内峰发生变形，热处理后的芒果果肉在80℃前仍保持分子结构和荧光强度，而温度升高可能导致酚类化合物分解，荧光发射增强。这些发现突出了同步荧光光谱在评估果汁质量、优化加工条件、确保产品真实性和消费者安全方面的有效性。

期刊介绍： Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
