Russia is said to be the great rival of this country in the growth of wheat, but I think it doubtful whether she possesses superior natural advantages; and I am sure she will find it difficult to compete with the industry and skill which here characterize the operations of husbandry, and the manufacture and shipment of breadstuffs.
Export of sophisticated and damaged flour.—It is a matter of deep regret that circumstances have occurred which must have a most injurious influence upon the trade in breadstuffs between this country and Great Britain. I refer to the mixtures of damaged, inferior, and good kinds of flour, which it appears on authentic testimony have been largely exported during the past year. Whether this fraudulent operation, which is said to have been principally confined to New York, is the result of the change in the inspection laws, as some assert, I am unable to say. But it requires no great foresight to predict that, if continued, it will create a distrust of our breadstuffs in foreign ports which it will be very difficult to remove. It cannot but excite the indignation of the many honorable dealers, that the unworthy cupidity of a few individuals should lead to such disastrous consequences.
I have as yet been unable to obtain samples of these sophisticated flours, and the only information which I have in regard to them is the general fact above stated, and concerning the truth of which there can be little doubt. No means should be left untried to devise some mode by which these frauds can be easily and certainly detected.
Injury sustained by breadstuffs during their transport and shipment.—During the past year, I have had abundant means of determining the nature of the injuries which are often sustained by our breadstuffs in their transport from the particular districts in which they are grown and manufactured to our commercial depots, and in their shipment to foreign ports. As this is one of the most important points connected with these researches, I have devoted much time to its investigation. From the results of numerous analyses, I think it may be safely asserted, that of the wheat flour which arrives in England from various ports of the United States, a large proportion is more or less injured during the voyage. The same remark may be made in regard to many of the samples sent from the Western States to the city of New York. Their nutritive value is considerably impaired, and without more care than is usually exercised, they are entirely unfit for export.
In my former report, I adverted to one of the great causes of the deterioration which our breadstuffs often suffer during their transport and shipment. This was the undue proportion of the great disorganizing substance, water, under the influence of what usually occurs, viz., an elevation of temperature above the ordinary standard. My recent investigations have served only to strengthen these views. There is no doubt that these are the conditions which cause the change of the non-nitrogenous principles into acids (the lactic or acetic), while a portion of the gluten is thus also consumed.
I have tried a series of experiments in reference to the action of moisture upon various samples of wheat and wheat flour. The samples were placed for twelve hours in the oven of a bath with a double casing, containing a boiling saturated solution of common salt, the temperature of which was about 220 deg. Fahr. Subjected to this test,
| 100 grains of Milwaukie wheat lost | 12.10 grains. |
| 100 grains of Guilderland (Holland) wheat lost | 9.35 grains. |
| 100 grains of Polish Odessa red wheat lost | 10.55 grains. |
| 100 grains of Soft Russian wheat lost | 8.55 grains. |
| 100 grains of Kobanga wheat lost | 8.15 grains. |
After an exposure of the dried samples to the air for two or three days, they increased in weight from one to three grains in the hundred originally employed.
Nineteen different samples of wheat flour, which lost by exposure to the above heat from ten to fourteen grains in the one hundred, when similarly exposed to the air for eighteen hours, again increased in weight from 8.40 to 11.60 in the hundred grains originally employed.
These experiments show, what might indeed have been predicted as to the general result, that wheat in grain, if not less liable to injury than flour, yet if once properly dried, suffers much less from a subsequent exposure to air and moisture.
