Why SPE Is the Gold Standard for Antioxidant Isolation from Fruit Extracts Antioxidants such as polyphenols and flavonoids are critical for human health, offering protection against oxidative stress. However, isolating these compounds from complex fruit matrices remains challenging due to co-extraction of sugars, organic acids, and pigments. Solid-phase extraction (SPE) has emerged as the preferred […]

Common Artificial Dyes in Confectionery Products Artificial food dyes are widely used in the candy industry to achieve vibrant colors. Common examples include Tartrazine (E102, Yellow #5), Sunset Yellow (E110, Yellow #6), Allura Red (E129, Red #40), Brilliant Blue (E133, Blue #1), Indigo Carmine (E132, Blue #2), and Ponceau 4R (E124, Red #4). These synthetic

Chemical Complexity of Coffee Extracts Coffee is one of the most chemically complex beverages consumed globally, containing over 1,000 volatile and non-volatile compounds. The major classes include chlorogenic acids, caffeine, diterpenes (cafestol, kahweol), melanoidins (Maillard reaction products), lipids (triglycerides, sterols), and polysaccharides. This complexity poses significant challenges for targeted contaminant analysis, as matrix components can

Antibiotic Contamination Concerns in Honey Production Honey is a natural product prized for its purity, yet veterinary antibiotic residues—primarily tetracyclines (TCs) and sulfonamides (SAs)—are frequently detected due to their use in beekeeping for controlling bacterial diseases like American foulbrood. These residues pose risks of allergic reactions, antibiotic resistance propagation, and regulatory non-compliance. Maximum residue limits
