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.
Applies to sodium benzoate / sodium phenylacetate: intravenous solution. Along with its needed effects, sodium benzoate / sodium phenylacetate may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
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.
25/11/08 Levels of the preservatives benzoate and sorbate in soft drinks are within legal limits, according to a new survey by the Food Standards Agency. The survey ran between January and May 2008 and analysed 250 fizzy and still soft drinks from ten different regions in the UK.
It can be concluded that like other fruit juices, best quality nutritious apple juice prepared by pasteurization followed by 0.1% potassium sorbate plus 0.1% sodium benzoate (T 9) treatment was found most beneficial by securing highest score during sensory evaluation, microbial safety and retention of most of the nutrients during 3 months ...

Optimum HPLC separation was achieved using C18 column, with 1.5 mL/min. Excellent percent recoveries of sorbic acid (90.6 %) and benzoic acid (95.5%) were obtained with the standard deviation below 9. Four samples of beverages were analyzed including two brands of concentrated fruit juice and two brands of regular bottled fruit juice.
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.
Sodium benzoate, the sodium salt of benzoic acid, is generally used as a chemical preservative to prevent alteration or degradation caused by microorganisms during storage . Both sodium benzoate and benzoic acid exhibited inhibitory activity against a wide range of fungi, yeasts, molds and bacteria, . Sodium benzoate is more widely used in a ...
Sodium benzoate is a type of salt that occurs naturally in some foods but is more likely to be chemically produced and added as a food preservative. When used as a preservative, sodium benzoate is typically added to foods in only small amounts. The FDA allows a maximum concentration of 0.1 percent ...
Sodium benzoate is a preservative found in a variety of foods, beverages and condiments. While it is generally recognized as safe in small doses, sodium benzoate may cause harmful health effects under certain conditions. Learning the facts on sodium benzoate allows you to assess its risks and benefits more accurately.
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 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.
The Determination of Adulteration in Orange Based Fruit Juices Maireva S., Usai T., Manhokwe S. Midlands State University, Department of Food Science and Nutrition, P Bag 9055, Gweru, Zimbabwe ABSTRACT The main objective of the study was to determine adulteration in orange fruit juices in Harare, Zimbabwe. Stratified sampling
The other juices claimed to be 100% juice, some being from concentrate. The navel orange had the highest citric acid concentration, but per serving it is actually much lower in comparison to the juices because the average orange contains approximately 2 oz. of juice, much less than the 6 to 12 oz. fruit juice servings.
The addition of ethanolic extracts of clove protects the color of the juice by showing decreased non enzymatic browning. In sodium metabisulphite and clove extract containing non pasteurized juice there is no weight loss whereas there weight loss seen in juice containing black pepper and cinnamon extract.
method is not available for the determination of sodium benzoate assay. Rapid economical, reproducible and simple direct method was developed and validated for determination of sodium benzoate using high performance liquid chromatography (HPLC). Sodium Benzoate concentration estimated with isocratic elution using a mixture of buffer and
DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low, because of low sugar content ...
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).
PDF | This paper is devoted to determine the concentration of two types of food additives using continuous injection technique supported by a new software designed by the authors. This methodology ...

HPLC and LC-MS/MS methods for determination of sodium benzoate and potassium sorbate in food and beverages: performances of local accredited laboratories via proficiency tests in Turkey. Another method would include juice screening protocol by NMR, but these would require a library to be established (or bought) for quantifying levels.
Benzoic acid, in the form of sodium benzoate, is a widely used food preservative suitable for acid foods. Benzoic acid is often used in combination with sorbic acid at levels of 0.05 to 0.1%. Commonly used levels . 0.03-0.2% . Preservative . Citric acid. Citric acid is found naturally in citrus fruit. It i s widely used in carbonated drinks
Sodium benzoate is a food preservative found in soft drinks and acidic foods such as jams, sauces, fruit juice and pickles. Combined with vitamin C, this substance forms a carcinogen known to cause cancer.
In our study sodium benzoate was detected in the range of 14.70–64.10 mg/kg in fruit juice samples . The correlation coefficient between benzene and sodium benzoate (0.682) and benzene and ascorbic acid (0.503) in fruit juice samples was recognized as positive, strong and significant .
The Parkia juice was extracted from the edible pulp of African locust bean (Parkia Biglobosa). The extraction was done by gravity in a porous medium (sieve). Some portion of the juice were preserved using three different preservatives (Sodium benzoate, Benzoic acid and Citric acid) at different concentrations while some were kept unpreserved.
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 ...
