Biogenic amines (BAs) are natural components of food produced mainly during metabolism in animals and plants. The determination of BAs is important because of their potential toxicity and their potential use as food spoilage indicators. In the present study, a method for the determination of six BAs (putrescine, cadaverine, histamine, β-phenylethylamine, tyramine, and tryptamine) by Liquid Chromatog. – Tandem Mass Spectrometry (LC-MS/MS) with Atm. Pressure Chem. Ionisation (APCI) source has been used on trout samples (Salmo trutta) stored in ice for 15 days. The results showed that on day 15 quite large amounts of putrescine (76.530 mg/kg), cadaverine (85.530 mg/kg), tryptamine (25.210 mg/kg), and histamine (15.975mg/kg) were detected, while the other BAs remained low (β-phenylethylamine: 3.230 mg/kg, tyramine: 0.165mg/kg). Furthermore, microbiol. data (Total Vial Count- TVC, pseudomonas spp, and Shewanella putrefaciens) showed that trout samples became organoleptically unacceptable on day 12, while volatile compound anal. showed a significant increase in total amounts of alcs., aldehydes, and ketones on days 12 and 15. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Related Products of 868-57-5).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Related Products of 868-57-5
