Identification and characterization of potent odorants responsible for typical and storage-induced flavors of cola-flavored carbonated beverages
… predominant in all regular colas. Guaiacol and linalool were predominant odorants in at least one brand, while 1,8-cineol was a moderately potent odorant in all colas. In addition, aroma profiles determined by sensory descriptive analysis were in good agreement with the potent odorants …

The Use of Solubility Parameters to Select Membrane Materials for Pervaporation of Organic Mixtures
… the pervaporation of a model solution containing linalool and linalyl acetate (major components of lavender essential oil), in ethanol. Published HSP values were collated for various polymers, and statistically analysed to determine variations in HSP values for polymer species. An investigation of …

Effect of canopy manipulation and fermentation on grape aroma components
… The total quantity of the bound geraniol, nerol, linalool, and a terpineol was higher in fruit from the leaf-pulled vines at harvest. Four strains of Saccharomyces cerevisiae were evaluated for their influences on free and conjugated aroma components of White Riesling grapes, immediately following …

In Vitro Study of an Orange Oil Derived Alternative to Antibiotics in the Treatment of Bovine Mastitis
… Of four major compounds tested, only citral and linalool had significant inhibitory effects on S. aureus growth. In addition, they were capable of reducing pre-formed biofilms as well as association and invasion to bovine epithelial mammary cells. Part of this inhibition was due to downregulation …
