Careful factory control and some experience are 
required in the manufacture of concentrated juice, 
and more especially in the manufacture of calcium 
citrate or citric acid, scientific chemical advice is 
necessary or desirable in the first instance, unless 
the factory superintendent has received preliminary 
training in connection with the manufacture of these 
products. 
Possibilities One estate in Malaya has already 
in Malaya, taken up the cultivation of limes on 
a small commercial scale and it is 
intended in the first instance to manufacture con- 
centrated lime juice, for which the necessary plant 
has been obtained. There should be a good Eastern 
and probably an Australian market for the products, 
although whether this country can compete with 
the West Indies in the European and American 
markets remains to be proved. The chief difficulty 
at present is the supply of a suitable wood for 
barrels. In the case of citrate of lime or citric acid, 
which are solids, this difficulty does not arise, since 
barrels constructed from suitable local wood could 
probably be made. Wooden boxes or cases would 
also be quite satisfactory for the packing of citrate 
of lime or citric acid for export. In the case of the 
liquid products, raw lime juice, and concentrated 
lime juice, the barrels would have to be of better 
construction and of strong wood to prevent leakage. 
It is not possible in this place to include full details 
of the processes of manufacture of the various 
products, but full information on this subject, in- 
cluding methods, machinery, and cost of plant 
required, can be obtained on application to the 
Department of Agriculture.
