Stable and pleasant color emulsified meat products could be achieved if the pH in emulsification. raw materials was 6.0-6.2, and color formation occurred at
The second way is to mix 15% of fumaric acid with molten paraffin (melting point: 52,7 ° C) and the spray mixture in the air temperature is below 32,2 ° C. Spray particles harden almost immediately. Study under a microscope showed that they are spherical, uniform in size, fumaric acid crystals are completely covered with wax. To check the continuity and effectiveness of the coating suspension is prepared, treated with 1 g of wax fumaric acid dissolved in water at 21d ° C with constant stirring for 10 min. The solution is then titrated with a standard solution of sodium hydroxide, and the results showed the presence of only 1.2% of the free fumaric acid.
PHJ5'A ~ Meusel and R. A. Brunn (U.S. patent number 3,359,120 on December 19, 1967, the patentee-firm "The Baltimore Spice Company") have developed a method of processing meat emulsion designed to improve the color of salt products. Food acid or a mixture of food acids, such as fumaric acid, cover almost the entire film non-toxic, tasteless, water-resistant material, melting at subsequent processing meat emulsion. This acid (or acid) penetrates into the emulsion and accelerates the color formation, for example, during heating in the roasting chamber. As a coating, you can use different types of edible wax, hydrogenated vegetable oil, lard and various gidrogenizirovannyi acetylated monoglycerides. They should all be non-toxic and tasteless, chemically inert to fumaric acid and have a melting point in the range of 37, / - 82,2 ° C.
Found that of the well cover several ways. One way is that the 15/0 micronized fumaric acid are mixed with molten paraffin wax (melting point: 52,7 ° C). In the mixer, the suspension stirred until solidification, thus solidifying mass is broken into large pieces. Frozen mass is cooled in a stream of cold air to about 10 ° C, mixed with matter clumping warning, for example tricalcium phosphate and ground to a very fine powder. Found that almost 100% acid coated with paraffin, its particles are uniform in size (approximately 150-250 m), which is considered optimal. Acceptable, various sizes.
