The ability to render the potato into a convenient dry form at a low
figure prompted other countries, notably Japan and the United States
of America, to resort to similar methods, but to a different end.
The potato is rich in carbohydrates, and this fact suggested the
subsequent milling of the dry material into a flour, commercially
known as “farina,” which has proved a conspicuous commercial success.
The demand for this flour is expanding rapidly, because it serves as
excellent material for the preparation of bun-flours, cake-flours,
custard-powders, soups, and other foodstuffs, designed and marketed
with the primary idea of lessening the worries and labours of the
housewife.
Previous to the war the price for this imported article varied
between £25 and £35--$125 and $175--per ton, the cost of production
ranging from £14 to £20--$70 to $100--per ton. The margin of profit
was sufficiently wide to warrant the development of the process.
Under war conditions the price soared as high as £90--$450--per
ton, but subsequently dropped to about £45-£50--$225-$250. A very
marked diminution upon this latter figure is improbable, owing to the
increased manufacturing costs which now rule.
Therefore the question arises as to whether Britain cannot turn the
balance of her potato crop to greater commercial advantage. There is no
reason why we should not do so, seeing that in 1913 we imported over
40,000 tons of farina, while in 1917 the value of our importation of
this flour rose to £1,040,319--$5,201,595--for about 25,000 tons. It
must be conceded, however, that under present conditions less scope
exists for such a manifestation of enterprise in this country, seeing
that our potato crop is only about one-tenth of what Germany normally
raises. But the demand for the by-products in this country is every
whit as heavy and sustained as in Germany, while the fact that in this
raw material we have the base wherewith to revive an industry--the
production of starch--which Germany wrenched from us by unscrupulous
trading, alone should be sufficiently attractive to warrant such an
attempt being made. Our consumption of starch is heavy, exceeding
50,000 tons a year, while our purchases of dextrine and unpotable
methylic-alcohol, both of which can be made from the potato, run into
£70,000--$350,000--apiece during the year. Even the industrial alcohol,
despite the adverse taxation conditions which prevail, is in urgent
demand for many new industries.
