The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...

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.
The actual amount of food force-fed is much greater because water is added to the dry feed. For pellets, the typical composition is about 53% dry and 47% liquid (by weight). This is the equivalent of around 1,900 grams per day in total mass. [70] For whole grain, the cooked weight is about 1.4 times the dry weight. [71]
The combination of table salt with nitrates or nitrites, called curing salt, is often dyed pink to distinguish it from table salt. [6] Neither table salt nor any of the nitrites or nitrates commonly used in curing (e.g., sodium nitrate [NaNO 3], [7] sodium nitrite, [7] and potassium nitrate [8]) is naturally pink.
Sea salt being added to raw ham to make prosciutto. Salting is the preservation of food with dry edible salt. [1] It is related to pickling in general and more specifically to brining also known as fermenting (preparing food with brine, that is, salty water) and is one form of curing.
It was developed by Robert M. Koch in 1963 as an answer to the difficulties of using a feed conversion ratio to compare individual animals. [1] Effective use of RFI data can greatly improve beef cattle farm profits. [ 2 ]
Pascalization, bridgmanization, high pressure processing (HPP) [1] or high hydrostatic pressure (HHP) processing [2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.
