The advantages and disadvantages of natural casings and artificial casings


1, natural casings

Natural casing is pig, cattle, sheep viscera processing power of the digestive system orurinary system and become, different processing methods, divided into salted casings anddried casing two; natural casings pale red, white or milky white, dried casing is pale yellow,with a certain fragrance. Diameter of each interval of 2mm, from 24 to 40mm; salted casingsto soak cleaning before use, otherwise it will in the mature process will produce salt efflorescence.

Advantages: good elasticity, water holding capacity, good security, edible, water vaporpermeability, smoky infiltration, thermal shrinkage and the meat stuffing adhesion, and goodtoughness of solidity, high nutritional value.

Disadvantages: the size and shape of irregular, a limited number, and storage at that time notprone to infestation in the processing and, appeared empty and deteriorating stale.

2, synthetic casing, namely artificial casings, sheet or tubular film that animal skin, plastic,fiber, paper processing, including the following:

(1) cellulose casings: with natural fibers such as cotton, linen, wood and other plant fibers.

Advantages: good flexibility and breathability, in rapid thermal processing is also very stable,can also be smoked in wet conditions, color.

Disadvantages: not edible, not with the meat stuffing contraction.

(2) collagen casings: as raw material made of animal skins, tendons, etc..

Advantages: edible material, thick also unsuitable for consumption; good air permeability,easy to color.

Disadvantages: the thermal processing to the attention of the heating temperature, otherwise it will become soft.

(3) is usually used as the outer packing: plastic casing casing or products.

Advantages: has the property of barrier of air and water penetration and strong impact resistance, more varieties of different specifications, can be printed, easy to use, clean and beautiful, suitable for cooking products.

Advantages: can not eat.

(4) cellophane casing: is a cellulose film, paper soft and stretch and shrinkage, the cellulosemicrocrystalline body is arranged in parallel to the longitudinal, so the fiber strength,transverse strength is small.

Advantages: low cost than natural casing.

Disadvantages: improper use of easily broken
