Circumstances Impacting The Standard Of Meat.
Thursday, October 27th, 2011Throughout the period between the delivery and maturity of animals, their flesh undergoes very appreciable changes. As an illustration, when the animal is young, the fluids which the tissues of the muscular tissues comprise, possess a big proportion of what is known as albumen . This albumen, which can additionally be the chief component of the white of eggs, possesses the peculiarity of coagulating or hardening at a sure temperature, like the white of a boiled egg, right into a tender, white fluid, not soluble, or capable of being dissolved in water. As animals get older, this peculiar animal matter gradually decreases, in proportion to the opposite constituents of the juice of the flesh. Thus, the explanation why veal, lamb are white, and without gravy when cooked, is, that the large quantity of albumen they comprise hardens, or turns into coagulated. Then again, the rationale why beef and mutton are brown, and have gravy , is, that the proportion of albumen they include, is small, compared with their higher amount of fluid which is soluble, and not coagulable.
The quality of the flesh of an animal is considerably influenced by the nature of the meals on which it has been fed ; for the food provides the fabric which produces the flesh. If the food be not appropriate and good, the meat cannot be good either. To the experienced on this matter, it’s well known that the flesh of animals fed on farinaceous produce, equivalent to corn, pulse, &c., is agency, properly-flavoured, and also economical within the cooking; that the flesh of these consumed succulent and pulpy substances, corresponding to roots, possesses these qualities in a considerably less degree; whilst the flesh of these whose meals incorporates fastened oil, as linseed, is greasy, excessive colored, and gross within the fat, and if the food has been used in giant portions, possessed of a rank flavour.
It’s indispensable to the good quality of meat, that the animal should be perfectly wholesome at the time of its slaughter. Nonetheless slight the disease in an animal could additionally be, inferiority in the high quality of its flesh, as meals, is for certain to be produced. Generally, certainly, as the flesh of diseased animals tends to very rapid putrefaction, it becomes not solely unwholesome, but completely poisonous, on account of the absorption of the virus of the unsound meat into the techniques of those that partake of it. The exterior indications of fine and bad meat will most likely be described under its own explicit head, however we might here premise that the layer of all wholesome meat, when freshly killed, adheres firmly to the bone.
Another circumstance greatly affecting the quality of meat, is the animal’s treatment earlier than it is slaughtered . This influences its worth and wholesomeness in no inconsiderable degree. It is going to be easy to understand this, after we mirror on these main rules by which the lifetime of an animal is supported and maintained. These are, the digestion of its meals, and the assimilation of that meals into its substance. Nature, in effecting this course of, first reduces the meals in the abdomen to a state of pulp, under the identify of chyme, which passes into the intestines, and is there divided into {two} ideas, each distinct from the other. One, a milk-white fluid, the nutritive portion, is absorbed by innumerable vessels which open upon the mucous membrane, or interior coat of the intestines. These vessels, or absorbents, discharge the fluid into a common duct, or highway, along which it’s conveyed to the large veins in the neighbourhood of the heart. Here it’s mixed with the venous blood (which is black and impure) coming again from each a part of the physique, and then it supplies the waste which is occasioned within the circulating stream by the arterial (or pure) blood having furnished matter for the substance of the animal. The blood of the animal having accomplished its course by all components, and having had its waste recruited by the digested food, is now obtained into the center, and by the action of that organ it is urged via the lungs, there to receive its purification from the air which the animal inhales. Again returning to the center, it is pressured by means of the arteries, and thence distributed, by innumerable ramifications, referred to as capillaries, bestowing to every a half of the animal, life and nutriment. The other precept the innutritive portion passes from the intestines, and is thus bought rid of. It’s going to now be readily understood how flesh is affected for unhealthy, if an animal is slaughtered when the circulation of its blood has been increased by over-driving, sick-usage, or other causes of excitement, to such a level of rapidity as to be too nice for the capillaries to carry out their functions, and causing the blood to be congealed in its minuter vessels. The place this has been the case, the meat might be darkish-coloured, and change into rapidly putrid; in order that self-curiosity and humanity alike dictate sort and mild remedy of all animals destined to serve as meals for man.
