How does sodium benzoate affect bacteria?

Sodium benzoate inhibits the growth of potentially harmful bacteria, mold, and other microbes in food, thus deterring spoilage. It’s particularly effective in acidic foods ( 6 ). Therefore, it’s commonly used in foods, such as soda, bottled lemon juice, pickles, jelly, salad dressing, soy sauce, and other condiments.

Is sodium benzoate antibacterial?

Antibacterial activities of sodium benzoate (NaB) in tryptic soy broth were tested. Lethality of acidified NaB against pathogens on cherry tomato was determined. The antibacterial activity of NaB was stronger at lower pH.

What is the mechanism of action of sodium benzoate?

Sodium benzoate is a preservative. As a food additive, sodium benzoate has the E number E211. It is bacteriostatic and fungistatic under acidic conditions. The mechanism starts with the absorption of benzoic acid into the cell.

What is the role of sodium benzoate?

In the food industry, sodium benzoate is used to prevent spoilage from harmful bacteria, yeasts, and molds. It also helps maintain freshness in food by helping to slow or prevent changes in color, flavor, PH, and texture. Other foods that commonly include sodium benzoate include: Salad dressings.

How does sodium benzoate inhibit microbial growth?

Sodium benzoate is food preservative that inhibits microbial growth. incubation time, sodium benzoate concentrations of 2.0 mg/mL increased chromosome break when comparing with the control group (P < 0.05). Sodium benzoate did not cause Ala40Thr (GCG→ACG) in superoxide dismutase gene.

How does a mixture of benzoic acid and sodium benzoate preserve food?

Benzoic acid and sorbic acid and their salts (sodium benzoate and potassium sorbate) are also used as preservatives and antimicrobials in foods; they act by the weak acid theory of disassociation after entering the cell cytoplasm, as described for other organic acids (21,55).

How does sodium benzoate work as a preservative?

Sodium benzoate preserves food by having anti-fungal properties, protecting foods from invasion by fungi that cause food to spoil and potentially make you sick. Sodium benzoate works by entering the individual cells in the food and balancing its pH level, increasing the overall acidity of the food.

What happens when you mix sodium benzoate and citric acid?

When potassium or sodium benzoate is mixed with citric acid or vitamin C, these ingredients react by forming a harmful new chemical called benzene. Benzene is a carcinogen associated with leukemia and other blood cancers.

Is sodium benzoate an organic compound?

Sodium benzoate is an organic sodium salt resulting from the replacement of the proton from the carboxy group of benzoic acid by a sodium ion. The sodium salt of BENZOIC ACID. It is used as an antifungal preservative in pharmaceutical preparations and foods.

Is sodium benzoate an acid or base?

Sodium benzoate is a salt of the conjugate base, the OBz- or benzoate ion. Whenever sodium benzoate dissolves in water, it dissociates into its ions. The benzoate ion then acts as a base toward water, picking up a proton to form the conjugate acid and a hydroxide ion.

How is sodium benzoate metabolized?

Sodium benzoate is a widely used preservative found in many foods and soft drinks. It is metabolized within mitochondria to produce hippurate, which is then cleared by the kidneys.

Is sodium benzoate an antioxidant?

Ascorbic acid (vitamin C) is a pure antioxidant, whereas sorbic acid (or sorbate salts) and benzoic acid (or benzoate salts) are pure preservatives. However, it is not completely clear why propyl gallate is considered an antioxidant or sodium sulfite is considered a preservative.

What is sodium benzoate used for in food?

Sodium Benzoate in Food & Beverage: This is the first additive ever approved by the FDA for inclusion in food, as it is able to prevent the growth of bacteria, mold, and other microbes. This will decrease the likelihood of spoilage and preserve the food for longer periods of time.

What is the structure of sodium benzoate?

Sodium benzoate is an organic sodium salt resulting from the replacement of the proton from the carboxy group of benzoic acid by a sodium ion. It has a role as an antimicrobial food preservative, a drug allergen, an EC 1.13.11.33 ( arachidonate 15-lipoxygenase) inhibitor, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor,…

What is the E number for sodium benzoate?

Sodium benzoate is a preservative. As a food additive, sodium benzoate has the E number E211. It is bacteriostatic and fungistatic under acidic conditions. The mechanism starts with the absorption of benzoic acid into the cell.

Is sodium benzoate in soft drinks bad for You?

In terms of beverages, you will often find this sodium salt in soft drinks, particularly diet sodas. This source of sodium benzoate also poses a number of risks, which will be explained below. [2] Over-consumption can lead to side effects. Photo Credit: Shutterstock
