Abstract
An acetic acid bacteria-containing composition comprising nonanal and methylheptenone, and having a peak area ratio of nonanal to methylheptenone (nonanal:methylheptenone), as determined by stir bar sorptive extraction thermal desorption gas chromatography-mass spectrometry (SBSE-GC/MS), of 1:10 to 100:1.
Claims15
A method for producing an acetic acid bacteria-containing composition,
- the method comprising (i) culturing an acetic acid bacteria, (ii) collecting the acetic acid bacteria after step (i), and (iii) drying the acetic acid bacteria after step (ii), wherein:
- the acetic acid bacteria is Acetobacter malorum;
- step (i) further comprises mixing the acetic acid bacteria with nonanal and methylheptenone so that the peak area ratio of nonanal to methylheptenone (nonanal:methylheptenone), as determined by solid-phase microextraction gas chromatography-mass spectrometry, is 1:10 to 100:1;
- and
- in step (i), the acetic acid bacteria comprises acetic acid bacteria, dimethyl trisulfide, and 2-tridecanone so that the peak area ratio of nonanal to methylheptenone (nonanal:methylheptenone) is 1:10 to 100:1, the peak area ratio of nonanal to dimethyl trisulfide (nonanal:
- dimethyl trisulfide) is 1:100 to 50:1, and the peak area ratio of nonanal to 2-tridecanone (nonanal:2-tridecanone) is 1:100 to 100:1.
