Reported found in tobacco, beans, coffee, malt, apple, grapefruit juice, grapes, raspberry, strawberry, asparagus, kohlrabi, carrot, celery, tomato, rye bread, smoked fish, cured pork, beer, cognac, rum, cider, sherry, grape wines, coffee, tea, peanut, popcorn,soybean, passion fruit, beans,starfruit,sesame seed, mango, cauliflower, tamarind, fig, corianderseed, rice, quince, rhubarb, dill, lovage root, corn oil, sweet corn, malt, wort, Texas sage, okra, cuttlefish and Chinese quince.

Uses

p-Vinylguaiacol is an aromatic substance and one of the compounds responsible for the natural aroma of buckwheat. It is also one of the major pyrolytic products of (E)-N-[(4-hydroxy-3-methoxy)-phenethyl]-3-[(3-methoxy-4-O-β-D-glucopyranosyloxy) phenyl] acrylamide; a new gycloside in tobacco.

Definition

ChEBI: A member of the class of phenols that is guaiacol in which the hydrogen para- to the hydroxy group is replaced by a vinyl group.

Preparation

From vanillin by reacting with acetic anhydride and sodium acetate yielding 3-methoxy-4-hydroxycinnamic acid on sub sequent hydrolysis; the latter, heated with quinoline in the presence of hydroquinone, is decarboxylated to 4-vinylguaiacol.

Aroma threshold values

Detection; 0.75 to 3 ppb
