The method depends on the reaction of p-aminodimethylaniline with hydroxymethylfurfural to form a soluble red product. Preparation of the reagent and method of application are presented.HMF formation in sherry making is affected by sugar content, baking time, and amount of aeration. HMF content in various California and Spanish sherry wines is reviewed. ER -
