For this reason, benzoic acid for human consumption was obtained by dry distillation of gum benzoin. FEMA Number 2131 . Acute Toxicity of Sodium Benzoate. Benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary … Benzoic acid, added as either its sodium or its potassium salt, is a preservative permitted in the United Kingdom by the Miscellaneous Additives in Food Regulations 1995. Benzoic acid is most commonly found in industrial settings to manufacture a wide variety of products such as perfumes, dyes, topical medications and insect repellents. The pK of benzoic acid is rather low (pK 4.20), so its main antimicrobial effect, due to the undissociated acid, will be for high acid foods such as ciders, soft drinks and dressings. 21 Products.

As mentioned for other organic acids, antimicrobial activity is greatest at low pH. The sodium salt is preferred because of the low aqueous solubility of the free acid. The process is catalyzed by cobalt or manganese naphthenates. Benzoate acts essentially as a mould and yeast inhibitor in high acid foods and the poor activity at pH values above 4.0 limits its use against bacteria. A quite new application method for benzoic acid is active packaging. Although benzene is a toxic and carcinogenic compound, the reaction causing this change has a very low chance of occurring in food. The effect results from greater permeability of the unionized form into microorganisms. The avoidance of organic solvents for the recrystallization makes this experiment particularly safe. Benzoic acid, which is usually used in the form of its sodium salt, sodium benzoate (Figure 9.1), has long been used as an antimicrobial additive in foods. However, as for sorbic and propionic acid, benzoic acid has a certain antimicrobial activity in the dissociated form (Chipley, 1993). 2-p-carboxyphenylpropionic acid. The metabolic breakdown pathways of benzoic acid. BENZENECARBOXYLIC ACID, BENZENEFORMIC ACID, BENZENEMETHANOIC ACID, BENZOIC ACID, BENZOIC ACID,, CARBOXYBENZENE, DRACYCLIC ACID, PHENYLCARBOXYLIC ACID, and PHENYLFORMIC ACID Structures of benzoic acid and sodium benzoate. Next to its natural occurrence in food, benzoic acid and its derivatives are also commonly supplemented as antibacterial and –fungal preservatives or flavoring agents (Del Olmo et al., 2017). Benzoic acid occurs naturally free and bound as benzoic acid esters in many plant and animal species. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances. 2- (Formylamino)benzoic acid. Levels of up to 24 mg/L have been reported in fermented cow's milk. Among the foods in which benzoic acid occurs naturally are cranberries, prunes, plums, cinnamon, ripe cloves, and most berries. The free acid form is poorly soluble in water and the sodium salt (sodium benzoate) is often used because of its greater solubility (Fig. Pesticide properties for Benzoic acid, including approvals, environmental fate, eco-toxicity and human health issues BA has inhibitory effects on the proliferation of bacteria and yeasts, a major cause of food spoilage. It is a common undergraduate preparation. Benzoic acid (C7H6O2) is a colorless crystalline copound. Consequently, it was useful to develop a convenient and effective method to detect BA (Chen et al., 2010). Benzoic acid (E210 or INS210, Table 2), a colorless aromatic carboxylic acid (Fig. Benzoic Acid Benzoic acid is the simplest aromatic carboxylic acid and an intermediate in the biosynthesis of secondary metabolites. Jakob Søltoft-Jensen, Flemming Hansen, in Emerging Technologies for Food Processing, 2005. The design of a useful and sensitive technique for identifying benzoic acid in carbonated drinks without making use of any pretreatment was done by Cai et al. U. S. production capacity of benzoic acid is estimated at 139,000 … [15] This synthesis offers a convenient exercise for students to carry out a Grignard reaction, an important class of carbon–carbon bond forming reaction in organic chemistry.[16][17][18][19][20]. Benzoic acid is an organic aromatic monocarboxylic acid. Laboratory Chemical Safety Summary (LCSS) Datasheet. Richard P.

Ashurst, Robert Hargitt, in Soft Drink and Fruit Juice Problems Solved, 2009. (1997) treated ionomer films with alkali. Different types of conventional methods, including thin layer chromatography, spectrophotometry (Lin and Huang, 2008), gas chromatography (GC) (Gonzalez et al., 1998), and HPLC (Cao et al., 2010), have been introduced for BA identification. 4-Carboxy-alpha-methylbenzeneacetic acid. [45] The oral LD50 for rats is 3040 mg/kg, for mice it is 1940–2263 mg/kg. Benzoic acid, C 7 H 6 O 2 (or C 6 H 5 COOH), is a colorless crystalline solid and the simplest aromatic carboxylic acid.The name derived from gum benzoin, which was for a long time the only source for benzoic acid. Benzoic acid. The salts and ester s of benzoic acid are known as benzoates . It is a conjugate acid of a m-toluate. Benzoic acid ≥99.5%, FCC, FG CAS Number 65-85-0. When benzoic acid (80 mg/kg body weight) and sodium bisulfate (160 mg/kg body weight) or their mixture (benzoic acid/sodim bisulfate = 80 mg/160 mg) were fed to mice for 10 weeks, the death rate was 66% from the mixture and 32% from benzoic acid alone. [44], For humans, the World Health Organization's International Programme on Chemical Safety (IPCS) suggests a provisional tolerable intake would be 5 mg/kg body weight per day. Non-food applications for benzoic acid's antibacterial function are found in cosmetics. The dry distillation of gum benzoin was first described by Nostradamus (1556), and then by Alexius Pedemontanus (1560) and Blaise de Vigenère (1596).[10]. In contrast, the Chinese laws keep BA addition at 200 mg kg− 1 as far as carbonated drinks are concerned. The temperature required can be lowered to 200 Â°C by the addition of catalytic amounts of copper (II) salts. Information on maximum allowed limits of benzoic acid and its salt as food additives can be found in the Codex Alimentarius (Food and Agriculture Organization of the United Nations and World Health Organization, 2017). The product contains significant amounts of chlorinated benzoic acid derivatives. There has been much public concern that some food additives cause adverse reactions, although investigations show that it is mostly based on misconception rather than on identifiable adverse reactions. Studies of the subacute toxicity of benzoic acid in mice indicated that ingestion of benzoic acid or its sodium salt caused weight loss, diarrhea, irritation of internal membranes, internal bleeding, enlargement of liver and kidney, hypersensitivity, and paralysis followed by death. Benzoic acid (BA) is a commonly used antimicrobial preservative in food and beverages, especially in carbonated beverages, as it presents its strongest antibacterial activity at pH 2.5–4.0. Benzoic acid structure (Source – PubChem) What is Benzoic acid? It also inhibits oxidative phosphorylation as well as the citric acid cycle and has a negative influence on cell walls. Benzoic acid is produced commercially by partial oxidation of toluene with oxygen. Benzoic acid has a low taste threshold and low volatility and wide antimicrobial spectrum (Ashurst, 1991). Benzoic Acid is a preservative that occurs naturally in some foods such as cranberries, prunes, and cinnamon. Paraben esters have antimicrobial activity against molds and yeasts and are used in beer, soft drinks, and olives. [25] Acidic food and beverage like fruit juice (citric acid), sparkling drinks (carbon dioxide), soft drinks (phosphoric acid), pickles (vinegar) or other acidified food are preserved with benzoic acid and benzoates. Benzoic acid, pentahydroxy- | C7H6O7 - PubChem. Benzoic acid was discovered in the sixteenth century. Benzoic acid is a plant polyphenol and a natural aromatic acid used in a wide variety of cosmetics as a pH adjuster and preservative 1.Benzyl Alcohol is metabolized to Benzoic Acid in the body. The phenol can be converted to cyclohexanol, which is a starting material for nylon synthesis. Benzoic acid is mainly consumed in the production of phenol by oxidative decarboxylation at 300−400 Â°C:[23]. Above that, the distribution coefficient between the fat and water phase is very unfavorable. This compound is gathered from the castor sacs of the North American beaver. 1 – 11 of 11 Results asthmatic) individuals. This weak acid and its salts are used as a food preservative. Benzoic acid levels in milk were also found to very sharply increase during fermentation, presumably due to the activity of lactic acid bacteria, Pseudomonas and/or Escherichia coli. Benzoic acid / bɛnˈzoʊ.ɪk / is a white (or colorless) solid with the formula C 6 H 5 CO 2 H. It is the simplest aromatic carboxylic acid. MDL number MFCD00002398.

BA has inhibitory effects on the proliferation of bacteria and yeasts, a major cause of food spoilage. I. Hahn-Ramssl, in Feed Additives, 2020. The provision of appropriate labelling is accepted by the UK government as an appropriate way of notifying the public of the presence of food additives, thus enabling informed choice to be made by the consumer. However, when using benzoic acid as food additive, care needs to be taken that the food product's taste is not altered in such way that it becomes unacceptable. Medicinal. Where benzoic acid is not wanted in products, it can usually be replaced effectively by the use of sorbic acid. Recently, benzoic acid has been prepared from toluene by employing TiO 2 nanotubes electrode. … Benzoic acid inhibits the growth of mold, yeast[24] and some bacteria. By continuing you agree to the use of cookies. Reactions of benzoic acid can occur at either the aromatic ring or at the carboxyl group: Electrophilic aromatic substitution reaction will take place mainly in 3-position due to the electron-withdrawing carboxylic group; i.e. Alfa Aesar™ Methyl 3-hydroxy-4 … Coupling of silica gel thin-film microextraction (TFME) was done to find out SERS (Surface Enhanced Raman Scattering) and the authors made use of the fast identification of BA in carbonated drinks. Lethal dose for cats can be as low as 300 mg/kg body weight. Among the food additives reported to cause adverse reactions are benzoic acid and its derivatives (E210–213), which may trigger asthma characterised by breathing difficulties, shortness of breath, wheezing and coughing in sensitive (i.e. Benzoic acid reacts with hydrogenating reagents to afford hexahydrobenzoic acid. What is it? Available in various quantities and reagent grades, it is used to produce phenol, plasticizers, benzoyl chloride, food preservatives, etc. Benzoic acid's most common uses are in carbonated beverages, pickles, sauces, and jelly. The process uses abundant materials, and proceeds in high yield.[13]. In the case of benzoic acids, because of the phenomenon of aromaticity, the presence of mesomeric effects greatly alters the acidity of these products.Thus, in the case of benzoic acids para-substituted by an electron-withdrawing group, the electron effect weakens the O-H bond in the acid, and thus increases its acidity … Benzoic acid is generally effective in controlling mold and inhibiting yeast growth and also in preventing a wide range of bacterial attacks 17). Benzoic acid's antimicrobial activity is primarily against yeasts and molds. Parabens are antimicrobial compounds chemically derived from benzoic acid. [37], In terms of its biosynthesis, benzoate is produced in plants from cinnamic acid. Molecular Formula. [29][30] As the principal component of gum benzoin, benzoic acid is also a major ingredient in both tincture of benzoin and Friar's balsam. These plasticizers are used similarly to those derived from terephthalic acid ester. Flavis number 8.021 . It has a role as an antimicrobial food preservative, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, an EC 1.13.11.33 ( arachidonate 15-lipoxygenase) inhibitor, a plant metabolite, a human xenobiotic metabolite, an algal metabolite … Benzoic acid retards the growth of yeast and moulds, the effective agent being the undissociated acid.

Table 9.3. It is one of the benzoates, which also includes sodium benzoate and potassium benzoate. CAS Number: 65-85-0. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The working mechanism of benzoic acid is based on the inhibition of enzymes belonging to the acetic acid cycle. Benzoic acid itself has low toxicity, but there has been concern because of a potential reaction that converts it to benzene. Such products have a long history of use as topical antiseptics and inhalant decongestants. Acidic food and beverage like fruit juice(citric acid), sparkling drinks (carbon dioxide), soft drinks(phosphoric acid), pickles(vinegar) or other acidified food are preserved with benzoic acid and benzoates. Its salts are used as a food preservative and it is an important precursor for the synthesis of many other organic substances. Chronic toxicities were examined using diets containing 0, 0.5, and 1 % of benzoic acid that were fed to male and female rats kept together for 8 weeks. The name is derived from gum benzoin, which was for a long time its only source. As the principal component of benzoin resin, benzoic acid is also a major ingredient in both tincture of benzoin and Friar's balsam. The major food groups contributing to dietary intake of benzoic acid are a wide variety of foods permitted at the following levels; various foods 200–1000 mg/kg (prepared salads, confectionery, etc. The dissociation constant is 6.46 × 10−5 (Bosund 1960 and 1962), which means that the pH that is reached applying lactic acid is already sufficient. [41] Benzoic acid is metabolized by butyrate-CoA ligase into an intermediate product, benzoyl-CoA,[42] which is then metabolized by glycine N-acyltransferase into hippuric acid. sodium benzoate is 180 times as soluble in water at 25°c as benzoic acid. This process usually gives a yield of around 65% [14]. Kalpana, V. Devi Rajeswari, in Preservatives and Preservation Approaches in Beverages, 2019. Ripe fruits of several Vaccinium species (e.g., cranberry, V. vitis macrocarpon; bilberry, V. myrtillus) contain as much as 0.03–0.13% free benzoic acid. The efficacy of benzoic acid and benzoate is thus dependent on the pH of the food. Beilstein/REAXYS Number 636131 . The acceptable daily intake (ADI) for benzoic acid is 5 mg/kg body weight. Benzoic acid is a precursor to benzoyl chloride, C6H5C(O)Cl by treatment with thionyl chloride, phosgene or one of the chlorides of phosphorus. No changes in normal patterns of growth, reproduction, or lactation during life were recorded and no morphological abnormalities were observed from the autopsies. Like other nitriles and amides, benzonitrile and benzamide can be hydrolyzed to benzoic acid or its conjugate base in acid or basic conditions. However, the pH of common margarine is only a little lower than that needed to ensure the efficacy of benzoic acid. However, these methods are time-consuming with complicated pretreatments and require expensive instruments (Pylypiw and Grether, 2000). [36] Cats have a significantly lower tolerance against benzoic acid and its salts than rats and mice. Benzoic acid (0.1%–0.2%) supplementation to broilers suppressed the growth in broiler chickens, the dry matter of the digesta increased in the crop and caeca, and decreased lactic acid bacteria and coliform bacteria (Jozefiak et al., 2010). M-toluic acid is a methylbenzoic acid carrying a methyl substituent at position 3. Chemically, parabens are esters made by combining benzoic acid and alcohols such as methanol or propanol. The resulting benzoic acid is subsequently degraded in the usual manner. (2018). In teaching laboratories, benzoic acid is a common standard for calibrating a bomb calorimeter. 68387. The lower aliphatic esters of benzoic acid are first hydrolyzed by esterase, which abounds in the intestinal wall and liver. Benzoic acid is an organic acid first used in foods almost 100 years ago. [43] Humans metabolize toluene and benzoic acid which is excreted as hippuric acid. The second generation was observed through its entire life cycle and the third and fourth generations were examined by autopsy. In butter, benzoic acid (<0.001%, Rudischer 1959) can be found naturally, stemming from the fodder. Laboratory investigations [32] as well as very recent theoretical work[33][34] have highlighted that derivatives of benzoic acid are promising for inhibiting the coronavirus (SARS-CoV). Benzoic acid preservative prevents or delays nutritional losses due to microbiological, enzymatic, or chemical changes of foods … Benzoic acid is also formed in apples after infection with the fungus Nectria galligena. The benzoic acid levels in raw cow's milk cheese ripened for 6 months can be as high as 250 mg/kg (Del Olmo et al., 2017). Tiny pieces of silica gel substrate were placed in an uncomplicated device that is made at home for conducting the TFME process and then determination of the BA content was done with the help of SERS after dropping colloidal gold onto the substrate. At a temperature of 130 o C, the density of this compound reduces to 1.075 grams per cubic centimetre. Welcome to PubChem! Benzoic acid /bɛnˈzoʊ.ɪk/ is a white (or colorless) solid with the formula C6H5CO2H. Typical levels of use for benzoic acid as a preservative in food are between 0.05–0.1%. Benzoic acid is used as a preservative in a wide variety of foods. The organic acids were equally effective in reducing L. monocytogenes when the frankfurters were stored at 4°C for 14 days (reduction around 3–4 log cfu/g) but when stored at 13°C, benzoate and diacetate were more effective than propionate and sorbate. the salt in solution is converted to the acid … Council of Europe no. Benzoic acid is a colorless crystal solid that can reduce the energy of the surface in a reaction. Benzoic acid is a compound comprising a benzene ring core carrying a carboxylic acid substituent. [26][27], Concern has been expressed that benzoic acid and its salts may react with ascorbic acid (vitamin C) in some soft drinks, forming small quantities of carcinogenic benzene.[28]. Benzoic acid is not allowed in all countries. In a comparative study, Islam (2002) investigated the effect of dipping turkey frankfurters in 25 per cent solutions of propionate, benzoate, diacetate or sorbate on the growth of Listeria monocytogenes. Benzoic acid is an extensively used food preservative. N-formylanthranilic acid. 2-formamidobenzoic acid. Justus von Liebig and Friedrich Wöhler determined the composition of benzoic acid. 1500 mg/kg; food supplements, preserved vegetables 2000 mg/kg; liquid egg 5000 mg/kg; cooked seafood 2000–6000 mg/kg) and soft drinks 150 mg/kg, alcohol-free beer 200 mg/kg (Sacramental grape juice 2000 mg/kg, liquid tea concentrates 600 mg/kg). Appreciable amounts are found in most berries (around 0.05%). Benzoic acid, aluminum salt. 21 . Formylanthranilic … This acid can be dissolved in water at less than 3 g per liter. Individual local authorities may have their own specific reasons for not wishing to purchase drinks containing benzoic acid. The first industrial process involved the reaction of benzotrichloride (trichloromethyl benzene) with calcium hydroxide in water, using iron or iron salts as catalyst. Find Similar Structures. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances. The resulting calcium benzoate is converted to benzoic acid with hydrochloric acid. Popular Documents: Specification Sheet (PDF) You have selected the … Benzoyl chloride is an important starting material for several benzoic acid derivates like benzyl benzoate, which is used in artificial flavours and insect repellents. Notwithstanding its approval for food use and GRAS status, the toxicology of benzoic acid and its derivatives has always been controversial (Del Olmo et al., 2017).
