Here, we report the identification and quantification of the molecular species of long-, medium-, and short-chain triacylglycerols (TAG) in butterfat (BF), including TAG with an odd number of acyl carbons (ACN) and TAG with unidentified molecular species. In the present study, in addition to auto-MS2, a large number of methods, each recording MS2 for 1–4(More)
This study uses normal-phase HPLC with on-line positive ion electrospray mass spectrometry (ESI-MS) to obtain quantitative compositional data on both synthetic and butterfat short-chain TAG. The product ion tandem MS of standards averaged 11.1 times lower in abundance of the ion formed by cleavage of FA from the sn-2-position for the pairs of regioisomers(More)
Cereulide producing Bacillus cereus was isolated from randomly chosen commercial infant foods. The cereulide production in infant food formulas was investigated. When the reconstituted foods were inoculated with >10(5) cfu ml(-1) of cereulide producing B. cereus, 2 to 200 microg of cereulide per 100 ml of food accumulated during 24 h of non-refrigerated(More)
