| Popis: |
A method using gas chromatography-mass spectrometry (GC-MS) with headspace solid-phase microextraction (SPME) was developed for the study of raw beef storage under two different temperatures (10oC and 4oC) in refrigerators. The headspace volatiles were extracted by 75-¦Im Carboxen-Polydimethylsiloxane (CAR/PDMS) fibers in a home-made extraction chamber, and separated by an XTI-5 capillary column. By studying the relationships between the amounts of certain volatiles formed on the beef samples and the storage days, as well as the bacterial counts, a strong correction (r iÝ 0.88) existed between the peak area response of 3-hydroxy-2-butanone and the storage days at both temperatures, showing that 3-hydroxy-2-butanone can be used for a quantitative indicator compound for monitoring the raw beef spoilage. |
