Tests for Caramel.—Valuable indications of the nature of an extract are obtained in the process of determination of vanillin and coumarin. Pure extracts of vanilla beans give, with lead acetate, a bulky, more or less glutinous, brown-grey precipitate, and a yellow or straw-coloured filtrate, whereas purely artificial extracts coloured with caramel give a slight dark brown precipitate and a dark brown filtrate. If both vanilla bean extract and caramel are present the precipitate is more or less bulky and dark coloured, and the filtrate is more or less brown. The soluticm remaining after extraction of the vanillin and coumarin with ether, if dark coloured, should be tested for caramel.

G. Gustavson, N. Demjanov,/. Prakt. Chem. 1888, 38, 201-207 in fact, the first allene to be synthesized was allene-1,3-dicarboxylic acid (glutinic acid B. S. Burton, H. v. Pech-man, Ber. Dtsch. Chem. Ces. 1887, 20,145-149), but its structure was only correctly assigned 67years later E. R. H. Jones,... 

Some like casein, salt free globulin and acid albumin are not heavily solvated in solution and are thus readily precipitated at the isoelectric point in a manner similar to the suspensions already considered. Others, e.g. glutin, gelatine and natural albumin, are solvated like silica which at the isoelectric point are not necessarily precipitated being maintained in the sol form by the solvent. On removal of the stabilising water however by the addition of alcohol or neutral salts precipitation will occur and this most readily at the isoelectric point.

Spallanzani in 1783 (Sumner and Somers, 1953), the enzymatic hydrolysis of taimin was described by Scheele in 1786 (Tauber, 1949), in 1814 Kirchhoff observed that a glutinous component of wheat is capable of converting starch to sugar and dextrin, and Vogel showed in 1817 that an iirfusion of oats would produce a fermentable sugar from milk (Roberts et a/., 1995).
