The structure and Sodium lactate

Wheat is one of China's large -scale cultivation of crops for a long time , a variety of pasta made ​​from wheat flour is preferred by the people of northern China 's staple food. However, the quality of wheat flour products affected species , origin, milling technology , Sodium lactate , the existence of mass fluctuations which are due to the composition of flour, starch , proteins, lipids , etc. , the ratio changes and quality caused by the change . And they often need to add some modifiers ( such as emulsifiers , antioxidants, enzymes , etc. ) to improve the quality and stability of the product and the production of pasta . CSL / SSL is the most widely used products in the face , the combined effect of the best emulsifier , it is often used as a "stabilizer" or " Insurance agent" in foreign mills to use, only the United States in 1996 reached 10 usage tons, the last year world demand rate of 6% --- 8% .
  The structure and properties 1.1 CSL

    Surface tension ( 0.1% concentration ) 37mN / m, CSL and extent of protein-protein interactions 95 , amylose complexed with the index 65. Security : FAO / WHO (1985) requirements , ADI is 0-20mg/kg, with 0.1 %, 0.5 %, 2.5% ( by weight ) CSL rats fed a diet for 3 months and no abnormalities, mice were oral LD50 10.985g/kg, has been identified by the U.S. Food and Drug Administration as GRAS substances ( substances generally recognized as safe ) .
    Application Regulations: Chinese : GB2760-1996 calcium lactate for cakes, breads. Maximum amount of 2.0g/kg
    USA : FDA 21 (FR172.844) provisions used as a dough conditioner , foaming agents, conditioners , limited to 0.5%
    Japan : Allow the use of its limited to bread 5.5mg/kg, cakes 8 mg / kg, Candy 5 g / kg of noodles 4.5g/kg.
    Britain and Europe : E482-ADI 0-20 mg / kg body weight. See the Community Bulletin 95/2 (OJNO. L 61 18.3.95) Additives ( England enacted legislation 1995 NO. 3187) Table 3 ( allowing the use of other additives ) , the EC announced 78/663 (OJNO. L 223 14.7.78 ) purity standards.

sodium lactate - the main purpose

Lactate
( A ) do emulsifiers, humectants, flavor -improving agent , quality -improving agent , antioxidant synergist and pH adjusting agents are widely used in meat food industry , to enhance the flavor , to inhibit the growth of pathogenic bacteria in food , extend product shelf life ;
( 2 ) JinDan Sodium lactate as a food preservative , flavoring agents , antifreeze, moisturizing agent , has replaced sodium benzoate as a preservative used in the food industry in some countries . Lactate compared benzoate , JinDan Calcium lactate, sodium sorbate there is not the same match advantage. In particular there are significant effect in meat products : 1 , to extend the shelf life : extended from 30 to 100% , or even longer ; 2 , inhibit pathogens in foods such as : HT E. coli , listeria bacteria proliferation of monocytes , Clostridium botulinum bacteria such as buds grow , thereby increasing food security ; 3, enhance and maintain the flavor of the meat ; 4 , as a salt can not only reduce the amount of sodium chloride , and sodium lactate salt of heart disease on high blood pressure patients , kidney patients, more secure . Prepared, for example potassium and sodium salts have balanced health .
