Introduction Lipid oxidation is a major concern in food science because it degrades nutritional quality, alters flavor, and generates potentially toxic compounds. Monitoring oxidation products is essential for ensuring shelf stability and consumer safety. Solid-phase extraction (SPE) has become a cornerstone technique for isolating these analytes from complex food matrices prior to chromatographic analysis. This […]

Why Polyphenols Matter in Fruit Juice Analysis Polyphenols are a diverse group of naturally occurring compounds found in fruits, vegetables, and beverages like fruit juices. They include flavonoids, phenolic acids, stilbenes, and lignans, and are widely recognized for their antioxidant, anti-inflammatory, and cardioprotective properties. For juice manufacturers and food scientists, quantifying polyphenol content is essential

Introduction Artificial sweeteners are widely used in the beverage industry to provide sweetness without the caloric load of sugar. Common sweeteners such as acesulfame-K (ACE), aspartame (ASP), saccharin (SAC), sucralose (SUC), and cyclamate (CYC) require robust analytical methods for accurate quantification. Solid-phase extraction (SPE) is a critical cleanup step to remove matrix interferences from sugars,

Why Caffeine Testing Matters in Beverages Caffeine is one of the most widely consumed psychoactive substances globally, found in coffee, tea, energy drinks, and soft drinks. Accurate quantification is critical for regulatory compliance, nutritional labeling, and quality control. Overconsumption can lead to health issues such as insomnia, palpitations, and anxiety, while under-reporting can mislead consumers.

Overview of GC-MS in Environmental Pollutant Analysis Gas chromatography-mass spectrometry (GC-MS) is a cornerstone technique for detecting and quantifying organic pollutants in environmental matrices. Its high sensitivity, selectivity, and ability to separate complex mixtures make it ideal for analyzing trace-level contaminants in soil, water, and air. Common target analytes include polycyclic aromatic hydrocarbons (PAHs), polychlorinated
