Gluconic Acid Food Grade As A Food Additive Can Do?
Gluconic Acid Food Grade as a food additive can do?
As a food additive Gluconic Acid Food Grade in use, there are many functions and functions. Which is more common there are four main points, respectively, as follows:
1, adjust the pH function:
Gluconic Acid Food Grade buffer pH of 3.4, suitable for low pH range of the buffer of food additives.
Drink pH4 below, generally sterilization time at 65 ℃ for 10 minutes, both to avoid the impact of sterilization heating on the beverage material, but also save energy, is the importance of beverage production engineering management part;
Other organic acid salt is difficult to achieve the following pH4 sterilization can achieve the above requirements, and Gluconic Acid Food Grade can meet the above requirements without affecting the beverage flavor, so the Gluconic Acid Food Grade is the best food processing pH buffer.
2, taste taste agent: Gluconic Acid Food Grade itself was taste good, have to cover up the bitter ignorant, odor function, such as cover fish smell, magnesium bitterness and so on, are superior to other organic acid salt.
3, cover the soybean protein smell: soy protein high nutritional value, used in meat processing, fish, surimi, frozen food and other food, but there are inherent soybean protein smelly, so the use of limitations.
In sausage manufacturing, add about 5% of the Gluconic Acid Food Grade, there is a significant reduction in the effect of soy protein odor. Gluconic Acid Food Grade also masked soymilk, hamburgers and so on using soy protein foods unique to soybean eggs from the smell.
4, to improve the sweetness of high sweetness taste:
Low-calorie high-sweetness sweeteners are healthy, but in the taste of the general difficult and perfect taste of sugar compared.
After the foreign test, Gluconic Acid Food Grade has significantly improved the high sweetness sweetener aspartame, stevioside, saccharin taste, aspartame and Gluconic Acid Food Grade and can achieve the same sweetness of sugar.
Why Gluconic Acid Food Grade can not be replaced? What makes it take such an important position?
Mainly by the five aspects to decide, it is these five functions and uses that makes the Gluconic Acid Food Grade has been favorable.
First, for the steel surface cleaning agent:
Steel surface such as the need for plating, chrome, tin, nickel to adapt to special purposes, such as the manufacture of tinplate, galvanized sheet, the surface chrome (electricity), the billet surface are subject to strict cleaning.
So that the coating with the steel surface firmly bonded, this time its cleaning agent to add Gluconic Acid Food Grade will achieve a very satisfactory results.
Second, as a cement admixture:
Cement to add a certain amount of Gluconic Acid Food Grade, can increase the plasticity and strength of concrete, and a blocking effect.
Thirdly, the initial and final solidification period of the concrete, such as the addition of 0.15% Gluconic Acid Food Grade, can extend the initial settling time of the concrete by more than 10 times, that is, extend the plastic's plastic time from a few hours to a few days Does not affect its fastness.
Plasticity and retardation The initial setting time is very important in concrete operations. For example, in the high temperature season construction and large engineering operations, it is a difficult problem to delay the initial setting time. The Gluconic Acid Food Grade can satisfactorily solve this problem.
In addition, high temperature bonding oil wells is more difficult to add Gluconic Acid Food Grade concrete at 170 ℃ high temperature, within a few hours plastic, it can also satisfactorily solve the above problems.
Therefore, Gluconic Acid Food Grade as a cement admixture in foreign countries has been widely used in important construction projects, such as a large number of bridges in the Middle East.
But our domestic application in this area has not yet been applied, it is said that in the papermaking wastewater extraction of sodium cellulose sulfonate, the effect and Gluconic Acid Food Grade is simply comparable.
