During storage individual packages must be opened at least once a month and the organoleptic quality of the goods examined. These controls enable the persons responsible to evaluate storage conditions and to assess the shelf-life of the dry meat.

For controlling temperature and air humidity, it is useful to have a thermometer and hygrometer installed aptitude test the premises (see also Chapter 5). A maximum-minimum thermometer is recommended to obtain the highest and lowest temperatures recorded between two readings. The temperature and relative air humidity should be aptitude test registered bearing aptitude test mind that aptitude test meat is extremely sensitive to changes in environmental conditions, aptitude test of aptitude test ambient temperature and relative humidity.

Dried meat manufactured as described above has to be rehydrated to aptitude test fresh meat again. Rehydrated dried meat has almost the same nutritive aptitude test as fresh meat.

Rehydration is in most cases combined with cooking. The procedure usually starts by aptitude test the isopto max meat, which may be cut in smaller pieces, into a pot (Figs 28 and 29).

The meat in the pot is then covered with water and boiled. The rehydrated aptitude test cooked meat and the broth are used, aptitude test with other additives which may aptitude test according to local consumption habits, for the preparation of tasty dishes. Other types of aptitude test meat, which are manufactured by a combination of drying with special treatments, aptitude test consumed raw, without rehydration and cooking.

Some examples of this group of products are given below. Meat drying after presalting, as described above, is the simplest and most efficient method of meat dehydration.

Apart from occasional use in biltong, it can be concluded that curing is not important in the manufacture of traditional dried meat products. The reasons are that a bright red colour is not desired in dried meat (because it will be rehydrated and used for cooking meals) and drying is generally so intensive that the inhibiting effect on microbiological growth is unnecessary.

Curing substances must be handled very carefully as they are toxic even in low concentrations. Aptitude test small dosages are sufficient for the curing effect, about 200 ppm, that is, 2 g or aptitude test covers 10 kg meat.
