CONDITIONS AFFECTING THE QUALITY OF MEAT.
Throughout the period between the birth and maturity of animals, their flesh goes through really substantial modifications. For example, when the animal is young, the fluids which the tissues of the muscles include, have a large proportion of what is called albumen. This albumen, which is likewise the chief part of the white of eggs, possesses the peculiarity of coagulating or solidifying at a specific temperature, like the white of a boiled egg, into a soft, white fluid, no longer soluble, or capable of being dissolved in water. As animals age, this peculiar animal matter slowly decreases, in proportion to the other constituents of the juice of the flesh. Therefore, the reason that veal, lamb are white, and without gravy when prepared, is, that the big amount of albumen they contain hardens, or becomes coagulated. On the other hand, the reason that beef and mutton are brown, and have gravy, is, that the percentage of albumen they include, is little, in comparison with their higher amount of fluid which is soluble, and not coagulable.
The quality of the flesh of an animal is significantly influenced by the nature of the food on which it has actually been fed; for the food provides the product which produces the flesh. If the food be not appropriate and great, the meat can not be great either. To the experienced in this matter, it is popular that the flesh of animals fed upon farinaceous fruit and vegetables, such as corn, pulse, & c., is firm, well-flavoured, as well as economical in the cooking; that the flesh of those fed upon succulent and pulpy drugs, such as roots, possesses these qualities in a rather less degree; whilst the flesh of those whose food contains repaired oil, as linseed, is greasy, high coloured, and gross in the fat, and if the food has actually been made use of in large quantities, possessed of a rank flavour.
It is indispensable to the good quality of meat, that the animal needs to be perfectly healthy at the time of its slaughter. Nevertheless slight the illness in an animal may be, inferiority in the quality of its flesh, as food, is certain to be produced. Most of the times, indeed, as the flesh of diseased animals tends to very quick putrefaction, it ends up being not just unwholesome, but definitely poisonous, on account of the absorption of the virus of the unsound meat into the systems of those who participate of it. The external indications of good and bad meat will be described under its own certain head, however we may here premise that the layer of all wholesome meat, when newly eliminated, adheres securely to the bone.
Another situation considerably influencing the quality of meat, is the animal's treatment before it is butchered. This affects its value and wholesomeness in no inconsiderable degree. It will be simple to understand this, when we review those leading concepts by which the life of an animal is supported and maintained. These are, the digestion of its food, and the assimilation of that food into its substance. Nature, in effecting this process, first decreases the food in the stomach to a state of pulp, under the name of chyme, which passes into the intestinal tracts, and is there divided into two principles, each unique from the other. One, a milk-white fluid, the nutritive part, is soaked up by innumerable vessels which open upon the mucous membrane, or inner coat of the intestinal tracts. These vessels, or absorbents, discharge the fluid into a typical duct, or road, along which it is conveyed to the big veins in the neighbourhood of the heart. Here it is combined with the venous blood (which is black and impure) returning from every part of the body, and after that it supplies the waste which is occasioned in the distributing stream by the arterial (or pure) blood having furnished matter for the compound of the animal. The blood of the animal having actually completed its course through all parts, and having had its waste recruited by the digested food, is now received into the heart, and by the action of that organ it is urged through the lungs, there to receive its purification from the air which the animal inhales. Once more going back to the heart, it is required through the arteries, and thence distributed, by numerous ramifications, called veins, bestowing to every part of the animal, life and nutriment. The other concept the innutritive portion passes from the intestinal tracts, and is thus got rid of. It will now be easily understood how flesh is impacted for bad, if an animal is slaughtered when the blood circulation of its blood has actually been enhanced by over-driving, ill-usage, or other causes of excitement, to such a degree of rapidity regarding be too great for the veins to perform their functions, and causing the blood to be congealed in its minuter vessels. Where this has been the case, the meat will be dark-coloured, and end up being quickly putrid; so that self-interest and humanity alike determine kind and gentle treatment of all animals predestined to work as food for male.
