were 20.1 to 284.3 mg/kg in Doogh and fruit juice, respectively. Moreover, benzoate was detected in all dairy products ranging from 11.9 mg/kg in lactic cheese to 91.2 mg/kg in UF-Feta cheese. Akbari-adergani et al. (2013) also showed all of the Doogh samples in Iran contained sodium benzoate in the range of 18.3 to 2345.1 mg/kg and 25.9 percents

If the sodium and potassium concentrations in the fruit juice are outside the range of standards, the sample should be diluted accordingly. Calculation Multiply the concentration of sodium and potassium obtained from the graphs by the dilution factor, i.e. x100, to express the result in ppm or mg/l of sodium or potassium in the original fruit ...

sodium, potassium, or calcium salt. Benzoic acid is slightly irritant to the skin and irritant to the eye, whereas sodium benzoate is not irritant to the skin and is only a slight eye irritant. High concentrations of benzoic acid have as result a sour taste of beverages and other food matrices, which limits its content of application [1,2].
Analysis of fruit juices –I Objective To determine the acidity & content of sodium benzoate & total solids in samples of various fruit juices. Determination of total acidity The acidity of natural fruit juices is the result mainly of their content of various organic acids.
The developed method has proved its accuracy in vitamin C determination in fruit juice, having the value of the recovery of known quantities of ascorbic acid ranging between 94.35% and 104%. The highest values for ascorbic acid were obtained for natural juice made by fruit squeezing.
Abstract A rapid and reliable method is presented for the determination of the preservatives sodium benzoate and potassium sorbate in fruit juices, sodas, soy sauce, ketchup, peanut butter, cream cheese, and other foods.
I make some herbal a ayurvedic drug.i need to preservate by using sodium bensoate. So what is the amount i can use?
Sodium benzoate - Sodium benzoate(MW = 144) is a preservative. As a food additive, sodium benzoate has the E number E211. - It is bacteriostatic and fungistatic. - It is most widely used in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices and pickles (vinegar).
The HPLC determination of the preservatives was performed using a reverse phase C-18 column, and UV detection at 225 nm for sodium benzoate and 255 nm potassium sorbate. The percentage of preservative in the sample was calculated by external standard using authentic sodium benzoate and potassium sorbate.
extension of the product shelf life. Sodium benzo-ate, potassium sorbate and natam-ycin are general-ly used to control mold, inhibit yeast growth and some bacteria (1). Sodium benzoate, C7H5NaO2, is added to a wide range of food products like soft drinks and natural fruit juice with acidic environ-ment. Potassium sorbate, C6H7KO2, has a linear

The limits of detections (LODs) were determined from the calculation of S/N ratios for both sodium benzoate and potassium sorbate. The LOD values of sodium benzoate and potassium sorbate were found to be 0.023 and 0.001 mg/L for both HPLC and LC–MS/MS methods, respectively.
Sodium benzoate, which is a synthetic salt of benzoic acid known as E211, is another widely used additive in the food industry to protect products against biological pollution (such as bacteria and fungi); Fig. 2 shows the chemical structure of sodium benzoate (Tuormaa, 1994; Hong et al., 2009).
FRUIT JUICE 1.- Fruit juices and squash - general information . Classification - JUICE - Fruit juices are made from pure filtered fruit juice with nothing added. Sodium benzoate can be added as a preservative to extend the shelf life, but this is not essential. Properly pasteurised juice has a shelf life of several months.
However, sodium benzoate is more effective and preferred because it is approximately 200 times more soluble than benzoic acid. The soft drink industry is the largest user of benzoate as a preservative due to the amount of high fructose corn syrup in many carbonated beverages. determination of benzoic acid and sorbic acid requiresSoft

ABSTRACT. A procedure has been developed using anion exchange high pressure liquid chromatography (HPLC) which is capable of determining microgram quantities of two common food preservatives, sodium benzoate and sorbic acid, in citrus juices.
liqueurs, beers, fruit juices and soft drinks (Zhang and Ma, 2013). Despite its presence in several foods, population studies indicate that soda and juice in cartons are the main dietary sources of this preservative (Pongsavee, 2015). Sodium benzoate has been used for many years as a
The soft drink products most likely to ferment are mildly acidic types with low carbonation containing fruit juice and in these instances a preservative is added to prevent micro-biological spoilage. The most common preservatives used in soft drinks are sodium benzoate and potassium sorbate and they may be used in tandem.

fruit juice, soy sauce, jams and jellies, and other condiments, to inhibit decay. Since the early 1900s, benzoate has been widely used worldwide as a preservative due to its antimicrobial properties combined with its low toxicity and taste. Benzoate is most effective in an acidic environment (pH ≤4.5) and is not
Sodium benzoate, potassium sorbate and natamycin are generally used to control mold, inhibit yeast growth and some bacteria . Sodium benzoate, C7H5NaO2, is added to a wide range of food products like soft drinks and natural fruit juice with acidic environment.
soft drinks and fruit juices on the markets of Ghana. The concentration of benzoic acid in the samples was calculated by external standard method and the level of benzoic acid ranged from not detected to 564.00 mg/L for the soft drinks and from not detected to 148 mg/L for the fruit juice respectively. The mean recoveries for
The maximum amount of sodium benzoate and potassium sorbate was 251.50 ± 18.69 and 96.38 ± 38.56 ppm, respectively, while caffeine content was in the range of 293.48 ± 14.33 - 607.32 ± 135.33 ppm. Conclusion: HPLC permits the detection of sodium benzoate and potassium sorbate at very low concentrations.
Sodium benzoate is the ubiquitous preservative also known as E211. Sodium benzoate is an "almost natural" preservative made by neutralizing benzoic acid, a naturally occurring preservative that is found in apples, cranberries, plums, and prunes, with sodium hydroxide, which is also known as lye.
