methanol concentration → is a concern in → distilled fruit spirits
“Some distilled fruit spirits contain, normally, high quantities of methanol.”
Saccharomyces cerevisiae → is affected by → ethanol and heat at 48.8°C
“a synergistic killing effect of ethanol and heat at 48.8°C was demonstrated on S. cerevisiae”
aspartame → has no persistent changes → vital signs, body weight, standard laboratory tests, fasting blood levels of aspartic acid, phenylalanine, other amino acids, methanol, blood formate levels, 24-hour urinary excretion of formate
dose: 75 mg/kg per dayduration: 24 weeks
“No persistent changes over time were noted in either group in vital signs; body weight; results of standard laboratory tests; fasting blood levels of aspartame's constituent amino acids (aspartic acid and phenylalanine), other amino acids, and methanol; or blood formate levels and 24-hour urinary excretion of formate.”
methanol → has a maximum level → spirits
regulation: EC regulations
“These spirits adhere to maximum levels of methanol (potential toxic compound) and 2-butanol (potential flavor defect) fixed by EC regulations.”
Escherichia coli O157:H7 → can be killed by → lactate, ethanol, or a combination of the two agents
pH: 3time: 5 min
“The acid tolerance of Escherichia coli O157:H7 strains can be overcome by addition of lactate, ethanol, or a combination of the two agents. Killing can be increased by as much as 4 log units in the first 5 min of incubation at pH 3 even for the most acid-tolerant isolates.”
methanol crude extract of Myrtus communis → inhibited the growth of → all tested bacteria except C. jejuni
“The crude extract inhibited the growth of all tested bacteria except C. jejuni.”
methanol → respect → legal limits
source: spirits produced using fruit and honey spirits
“The methanol levels found in the different types of spirits are those expected based on the specific raw materials of each and, almost in all studies, respect the legal limits.”
