hence we continue to read that cocoa
usually contains arrowroot or other starch. In the old days this was
frequently so, but now, owing to many legal actions by Public Health
Authorities, this abuse has been stamped out. Nowadays if a Public
Analyst finds flour or arrowroot in a sample bought as cocoa, he
describes it as adulterated, and the seller is prosecuted and fined.
Hence, save for the presence of cacao shell, the cocoa of the present
day is a pure article consisting simply of roasted, finely-ground cacao
beans partially de-fatted. The principal factors affecting the quality
of the finished cocoa are the difference in the kind of cacao bean used,
the amount of cacao butter extracted, the care in preparation, and the
amount of cacao shell left in.

The presence of more than a small percentage of shell in cocoa is a
disadvantage both on the ground of taste and of food value. This has
been recognised from the earliest times (see quotations on p. 128). In
the Cocoa Powder Order of 1918, the amount of shell which a cocoa powder
might contain was defined--_grade A_ not to contain more than two per
cent. of shell, and _grade B_ not more than five per cent. of shell. The
manufacturers of high-class cocoa welcomed these standards, but
unfortunately the known analytical methods are not delicate enough to
estimate accurately such small quantities, so that any external check is
difficult, and the purchaser has to trust to the honesty of the
manufacturer. Hence it is wise to purchase cocoa only from makers of
good repute.

CHOCOLATE.

We have so far no legal definition of chocolate in England. As Mr. N.P.
Booth pointed out at the Seventh International Congress of Applied
Chemistry: "At the present time a mixture of cocoa with sugar and starch
cannot be sold as pure cocoa, but only as 'chocolate powder,' and with a
definite declaration that the article is a mixture of cocoa and other
ingredients. Prosecutions are constantly occurring where mixtures of
foreign starch and sugar with cocoa have been sold as 'cocoa,' and it
seems, therefore, a proper step to take to require that a similar
declaration shall be made in the case of 'chocolate' which contains
other constituents than the products of cocoa nib and sugar." We cannot
do better than quote in full the definitions suggested in Mr. Booth's
paper.

England, although in some of the European countrie
