Sodium diacetate - a new multi-functional food and feed additive
8-oxide catalyst into the citric acid cycle, fatty acid synthesis is the direct materials. Adipose tissue of young animals, anti-acetyl coenzyme A synthetase activity is very high, coenzyme A to acetate can be rapidly converted to acetyl coenzyme A, and then transformed into fatty acids and fat. Therefore, dietary sodium diacetate can significantly improve the cows, sheep milk fat and milk production. Palmitic acid (formula below) is assisted by a member of acetyl acid A and seven molecules of malonyl coenzyme A synthesis. . ,[link widoczny dla zalogowanych], 0f: (ix a c ≤, nl {3, adjust the ionization equilibrium of the enzymatic reaction in vivo must be within a certain range of PH, the enzyme activity only. Different enzymes require an optimal PH value, which is the activity of only the highest. PH affect enzyme activity, mainly due to the PH can affect the enzyme, especially active center of certain chemical groups of the ionization state. If the substrate is also the electrolyte, PH can also affect the ionization of substrate state. enzymatic reaction in the best PH value, just to make the enzyme and substrate molecules, the most appropriate ionization state is conducive to both Food Science and Technology 22 * Hangzhou, No. 2, 2004 total 73, and the combination of catalytic reaction. acetic acid and sodium acetate to form a conjugate acid-base pairs, it is the ability to regulate PH value, equal to PKai1, acetic acid Pka ---- 4.76, that is, with the proportion of different concentrations of acetic acid and acetic acid , can guarantee PH in 3.76 - 5.76 PH value between the maintenance of a constant 4. seasoning sour sodium diacetate can not only cover up the other drugs in feed additives, odor; while it is itself a good The flavoring agent, increase the feed of the relevance of I = l, played increase appetite, increase the animal's daily intake of animal growth and development play a good role in promoting. In summary, the SDA is not only widely spectrum efficient preservation of mildew inhibiting mold, but it also has many important physiological functions, the physiological metabolism of animals play an important role in promoting growth and development with a feature or a good nutritional additives. four, two sodium acetate in the application of a food production, food, grain, rice and products diacetate for food, cereals, rice and its products has an excellent anti-virus effect. in the grain moisture content of about 21.5 to add 0. 1 a O.8 of the diacetate, grain storage period can be extended from the original 9O days to 200 days. diacetate for rice products have a good anti-virus preservation effect. be applied to the Guangdong Pho (Alchemy Powder ) the preservation, add the rice milk 0.2 sodium diacetate, make steamed rice noodle extended shelf at room temperature 1 day, if the calcium propionate sodium diacetate and pour mixture ratio of 1:1 , the same dosage of fresh rice noodles can extend the period of more than 2 days. In addition, the sodium diacetate on the corrugated surface, yuba,[link widoczny dla zalogowanych], tofu and other rice products also have good mildew, corrosion effects. the national standard GB2760 - 1996 requirements maximum use levels of 1 g / kg 2. diacetate bakery for bread, cakes and other foods of the mold, you can completely replace calcium propionate (sodium diacetate cheaper than C). As the two synergistic the role of complex mold can greatly increase the use of the effect of addition of the mixture is generally below 0.3. diacetate for Cantonese-style moon cake to the preservation, in the crust can be achieved in 0.3 mildew effect, is a good DMF substitute. 3, puffed food diacetate containing free acid,[link widoczny dla zalogowanych], but only 4O about its content, so its gentle acidity than acetic acid, but asked not to be sour in the need to place strong , sodium diacetate can play a role just right, because preservative is sodium diacetate as sour agent, nutritional agent, it can be widely used extruded food sauce. \additional species) provides, sodium diacetate in the Expanded Food and puffed food the maximum amount of seasoning 1O g / kg,[link widoczny dla zalogowanych], the largest in the fried potato chips was 1 g / kg. 4, other food diacetate can also be used in many other food Preservation. For example, the jelly can be used as food preservatives, acidity regulator and, when the addition level 0.1 ~ O. 3, room temperature jelly save up to 3O-day period (not sealed packaging); for edible oil, add the safety limit of 0.1; in meat products, candy maximum limit of 0.1; in gravy and limit sauce sauce 0.25; in snacks, the maximum addition level 0.05 points in mind. Foreign Application diacetate in foods has been very mature, but in the country, both production and development,[link widoczny dla zalogowanych], or application, still in its infancy, so strong in the domestic food industry to develop and promote the SDA has a very bright future.
