Sodium Benzoate, also known as benzoic acid, it is also known as Sodium Benzoate sodium benzoin. E211 is insoluble in water at room temperature in air (especially the hot air) in the micro-volatile, hygroscopic, about room temperature 0.34g/100ml; but soluble in hot water; soluble in ethanol, chloroform and non-volatile oil. In the use of multi-use Sodium Benzoate; acid and E211 and corrosion resistance traits are similar. E211 mostly white granules, odorless or slight benzoin smell, taste sweet, with convergence; soluble in water (room temperature) 53.0g/100ml around, PH of 8 or so; E211 is the acid preservatives in the alkaline medium no bactericidal, antibacterial; Sodium Benzoate corrosion is the best PH 2.5-4.0, when the 5% solution PH5.0 bactericidal effect is not very good. E211 lipophilic large, easy to penetrate the cell membrane into the cell body, interference with membrane permeability, Sodium Benzoate can inhibit the absorption of amino acids the cell membrane; into cells in vivo acidification of intracellular ionized alkaline reserve, and inhibit cell respiration enzyme activity, to prevent condensation of acetyl coenzyme A, Sodium Benzoate to play the purpose of food preservation.

Sodium Benzoate synthesis:
By the toluene in the presence of cobalt naphthenate catalyst to air oxidation system to take the first acid, then acid as raw materials, each with sodium bicarbonate, active carbon, then the results of filtration, drying, crushing obtained Sodium Benzoate.

Sodium Benzoate for oral liquid pharmaceutical preservatives, Sodium Benzoate sour to prevent deterioration and prolong shelf life effects, Sodium Benzoate human liver would be too much the amount of harm, and even cancer, according to GB2760-1996 national health standards in the meat may not be used in the food system, Sodium Benzoate.

It is used less than sodium benzoate in past years, but now it seems the market demand is increasing. Potassium benzoate is used as a substitute preservative for sodium benzoate primarily in acidic foods where the sodium content needed to be lower. The following food may contain with it:

soda
juice
cider
margarine
syrup
jelly
dressing
And let’s have a closer look at what soda manufacturers say about it.

Coca Cola: used as a preservative and to protect taste. (2)
Pepsico: in the carbonated soft drinks, such as in Diet Pepsi and Sierra Mist to preserve freshness. (3)
Properties
Solubility
In water: 73.83 g/100 mL (25 °C) in water, approximately 21 times that of benzoic acid, 3.44 g/L (25 °C). It dissociates into two distinct parts in water, the benzoate anion and potassium cation. The benzoate anion is the conjugate base of the benzoic acid.

In organic solvents: soluble in ethanol, slightly soluble in methanol, insoluble in ether.

PH
The pKa of benzoic acid is 4.2. The preservation function is better in low-pH products, below 4.5 or below its pKa.

Preservation Mechanism
The mechanism of action is the same with that of sodium benzoate, and also similar to sorbates, but different with the bio preservative – natamycin. Benzoic acid forms when potassium benzoate dissociates in water and combines with proton. The undissociated benzoic acid enters the microbial cell and inhibits cell growth. This is how it works and plays a role in food preservation.

Crystalline fructose has three advantages: with low glycemic-index, it can enter into intestine directly and be digested and absorbed without being metabolized, which will be good for health; it can present streptococcus in oral cavity from producing dextran because it cannot easily be changed into acid by the streptococcus in oral cavity.

Crystalline fructose will not cause decayed tooth; it can control people’s weigh effectively by increasing the felling of satiety and reducing fat because it is sweeter than cane sugar but with lower calorie.

Definition: Purified and crystallised D-fructose with a fructose content of not less than 98.0%, and a glucose content of not more than 0.5%. It has the same chemical formula with glucose but a different molecular structure.

Is it A Sugar?
Yes, it is a monosaccharide. Another two monosaccharides are glucose and galactose.

Is it Natural?
Yes, it is a natural sweetener instead of an artificial sweetener as fructose occurs naturally in fruits and vegetables, as well as honey.

How Much the Calories?
95% of the caloric value of sucrose. (1) It can control calorie intake as it is much sweeter than table sugar.

Sweetness
It has the highest sweetness among naturally occurring sugars. Its sweetness is 1.3 to 1.8 times that of sucrose.

To reach the same sweetness, its usage can be reduced compared with sucrose.

Sweetness is its most important characteristic against other advantages. Its sweetness is not fixed, but changes with the temperature. The lower the temperature, the greater the sweetness.

Flavor Enhancement
The taste buds in the tongue perceive fructose firstly compared with glucose and sucrose, and the perception disappears rapidly.

Fructose does not mask the flavor release of glucose and sucrose as its peak of flavor release appears before glucose and sucrose. As a result, the flavor of beverage will not be improved and/or maintained by the addition of crystalline fructose.

The product Calcium Chloride is colorless square crystal, ordinarily in white or white cavernous and honeycombed. It is easily soluble in water and the solution is subacid. It is mainly applied in the desiccant and used as the dehydrating agent for producing alcohol, ester, ether allyl resin. It can be also used for processing and deinking the waster paper. It is the raw material in producing calcium salt. The solution can be used as the flocculating agent in the industries such as sodium alginate and bean product.
