Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a continuous emulsification device for frozen meat such as fish meat and livestock meat.

[Prior Art] and [Problems to be Solved by the Invention] The animal proteins consumed by humans are mainly fish and livestock meat, and these fish and livestock meats contain free water and bound water in their components. Free water contains 75 to 85% of the total water content, and contains a large amount of delicious water-soluble protein.

The method of adding salt to prevent this moisture from escaping has been around for a long time.Actomyosin, a super-large molecule, is produced from salt-soluble proteins, which has water-retaining properties.
It improves binding properties and prevents moisture from escaping.

Actomyosin is formed by the action of salt on actin, which is unstable like myosin, which is unstable alone, and myosin in particular is a factor that increases water retention and binding.

The biggest impediment to the formation of actomyosin is thermal denaturation, and suppressing the heat generated during cell crushing that occurs during emulsification of meat such as fish and livestock meat is the most important factor in producing delicious foods.

Furthermore, in addition to the above-mentioned method of using salt as a technique to prevent moisture from escaping from meat, there is also an emulsification method in which an emulsifier or an emulsifying compatible food is added.
Starch, soybean, milk, gelatin, etc. are used. Incidentally, the egg used in the mayonnaise production method acts as an emulsifier, and is one of the known emulsification techniques.

In addition, there are also known mashing machines that break the muscle cells of meat and add and mix salt, emulsifiers, emulsifying compatible foods, etc. to improve water retention and cohesiveness. Batch processing methods, such as those that mechanize manual work such as putting fish meat in a container and crushing it with a grinder, or those that use a silent cutter that cuts with a knife, do not necessarily have sufficient productivity for grinding. Not only is there a defect that tends to cause variations in quality, but recently, in order to improve the productivity and stability of quality of mashed products, the contact of the cutter is improved, and vacuum containers are used to remove air. As efforts are being made to prevent contamination and the delicate technical operations performed by humans are replaced by computers, the machines themselves have become larger and more complex, increasing their initial costs. The current situation is that
