Patrons of a pub evaluated regular beer and "MIT brew" (regular beer plus a few drops of balsamic vinegar) in one of three conditions. One group tasted the samples blind (the secret ingredient was never disclosed). A second group was informed of the contents before tasting. A third group learned of the secret ingredient immediately after tasting, but prior to indicating their preference. Not su...

This work proposes the elaboration of a product based on maceration Sherry Vinegar together with pineapple in order to extract certain volatile compounds that can be found pineapples, giving final new organoleptic properties and increased polyphenolic content. Maceration trials were carried out application microwaves ultrasound, which reduced time from traditional three-day solid-liquid just fe...

Majchrowicz and Hunt1* have reported that sodium acetate has an inhibitory effect on the rapid increase of blood ethanol concentration following oral administration of ethanol. Mochizuki et al.2'3) have reported that acetic acid and vinegar also have this effect. It is considered that many dietary factors have effects on the blood glucose concentration after a meal,4>5) so we examined the effec...

The present study aimed to investigate major volatile compounds, organic acid, phenolic and mineral contents, antiradical antimicrobial properties of home-made apple/grape vinegar. Grape vinegar showed higher total acidity, acid content, content (TPC), activity lower minimum inhibitory concentration (MIC) values compared apple While acetic tartaric acids were the most abundant in grape vinegar,...

Soil contaminations by heavy metals near oilfields have been widely reported and are causing great concern. Thus, it is highly desirable to develop cost-effective materials methods avoid metal residues contaminating soil food. An effective, environmentally friendly, inexpensive remediation material for metal-polluted was designed prepared using biochar (BC) combined with humic acid (HA) resulti...
