Meat off-cuts were, until the 1950s, preserved in aspic, a gel made from gelatin and clarified meat broth. Another form of preservation is setting the cooked food in a container and covering it with a layer of fat. Potted chicken liver can be prepared in this way, and so can potted shrimps, to be served on toast.
Potted meat is a form of traditional food preservation in which hot cooked meat is placed in a pot, tightly packed to exclude air, and then covered with hot fat. [ 1 ] [ 2 ] As the fat cools, it hardens and forms an airtight seal, preventing some spoilage by airborne bacteria . [ 3 ]
Additionally, the hurdle effect of food preservation, such as by adding lactic acid bacteria and salt to a food product, is illustrated and described. [ 11 ] [ 12 ] [ 13 ] This figure illustrates the pathway of food preservation followed by lactic acid bacteria involving nisin , as well as the pathway of food preservation followed by salt.
Meat can be replaced by, for example, high-protein iron-rich low-emission legumes and common fungi, dietary supplements (e.g. of vitamin B 12) and fortified foods, [152] cultured meat, microbial foods, [153] mycoprotein, [154] meat substitutes, and other alternatives, [155] such as those based on mushrooms, [156] legumes (pulses), and other ...
While meat-preservation processes like curing were mainly developed in order to prevent disease and to increase food security, the advent of modern preservation methods mean that in most developed countries today, curing is instead mainly practiced for its cultural value and desirable impact on the texture and taste of food.

Human food is food which is fit for human consumption, and which humans willingly eat. Food is a basic necessity of life, and humans typically seek food out as an instinctual response to hunger ; however, not all things that are edible constitute as human food.
The spoilage of meat occurs, if the meat is untreated, in a matter of hours or days and results in the meat becoming unappetizing, poisonous, or infectious. Spoilage is caused by the practically unavoidable infection and subsequent decomposition of meat by bacteria and fungi, which are borne by the animal itself, by the people handling the meat, and by their implements.
