Description:

Benzoic acid is a colorless crystalline solid and a simple aromaticcarboxylic
acid. The name is derived from gum benzoin, which was for a long time its only
known source. Benzoic acid occurs naturally in many plants and it serves as an
intermediate in the biosynthesis of many secondary metabolites. Salts of
benzoic acid are used as food preservatives and benzoic acid is an important
precursor for the industrial synthesis of many other organic substances. The
salts and esters of benzoic acid are known as benzoates.

Benzoic acid is often used as drug or the use of preservative, anti fungal,
bacterial, fungal growth, medicinal is painted on the skin, used to treat
ringworm of the skin disease. It is used for synthetic fiber, resin, paint,
rubber, tobacco industry. Initially benzoic acid is obtained by an interest gum
distillation or alkaline hydrolysis and by hippurate hydrolysis. In industrial,
benzoic acid is obtained in cobalt, manganese catalyst by air oxidation of
toluene; or by phthalic anhydride hydrolysis decarboxylation of benzoic acid
and its sodium salt can be used as latex, toothpaste, jam or other food
antimicrobial agent, also can be used for dyeing and mordant.

Usage:

1.Used as a chemical reagent and preservative.
2.Benzoic acid is important type food preservative. Under acidic conditions, It
has inhibitory effects to mold, yeast and bacteria , but the effect is weak
acid producing bacteria. The most appropriate antimicrobial pH values is
ranging from 2.5 to 4, generally lower, the pH value is appropriate from 4.5 to
5. In the food industry with plastic barrels concentrated fruit and vegetable
juice, the maximum use amount shall not be over 2.0g / kg; in jam (excluding
canned), (taste) juice drink, soy sauce, vinegar in the maximum dose of
1.0g/kg; in soft candy, wine, wine in the maximum dose of 0.8 g / kg
separately; in the low salt pickled vegetables, the sauce, candied fruit,
maximum dose is 0.5 g / kg; in carbonated drinks in the largest amount of use
is 0.2g/kg. due to benzoic acid, slightly soluble in water, its use can be a
small amount of ethanol enable dissolved.
3.Preservative; anti microbial agents. Due to the low solubility of benzoic
acid and use shall be stirring, or dissolved in a small amount of hot water or
ethanol. When used in the soft drink with fruit juice concentrate, for benzoic
acid easy volatile with the water vapor, so often used in the sodium salt,
besides the above sodium equivalent to benzoic acid 0.847g.
4.Often used as a fixative agent or preservative. Also used as a fruit juice
aroma conservation agents. As a perfume with perfume fragrance. Can also be
used for chocolate, lemon, orange, berries, nuts, candied fruit type edible
essence. Tobacco flavor is also commonly used.
5.Benzoic acid and its sodium salt are food preservatives. Under acidic
conditions, it has inhibition of yeasts and molds. When pH 3, antibacterial
strength and when pH 6, many fungi effect is very poor, so the antibacterial
optimum pH is 2.5-4.0. Benzoic acid is mainly used for the production of sodium
benzoate preservatives, dyes intermediates, pesticides, plasticizers, mordant,
medicine, spice and also can be used as alkyd resin and polyamide resin
modifier for the production of polyester, terephthalic acid and used equipment,
iron and steel anti rust agent.
6.Mainly used for antifungal and antiseptic.
7.Used in medicine, dye carriers, plasticizer, spices and food preservatives
such as production, and can also be used to paint of alkyd resin performance
improvement; used as pharmaceutical and dye intermediates, used for the
preparation of plasticizer and spices etc., as well as equipment, iron and
steel anti rust agent.

The Method of use of food additives:

1. the antibacterial activity of benzoic acid molecule was higher than that of
the ions, so When pH is less than 4, antibacterial activity is high, the
minimum inhibitory concentration is 0.015%-0.1%. but in acidic solution in the
solubility decreased, so do not rely solely on the improvement of the solution
of acid to improve its antibacterial activity. Benzoic acid of optimum
antibacterial is pH 2.5 ~ 4.
2. Due to the low solubility of benzoic acid in water, so the actual is added
just the right amount of sodium carbonate or sodium bicarbonate, with more than
90¡æ dissolved in hot water, making it into benzoic acid sodium then added to
the food. If you must use of benzoic acid, first with the amount of dissolved
in ethanol before use.
3. Because the solubility of benzoic acid in water is lower than sodium
benzoate , so the use of sodium benzoate in acidic foods should pay attention
to prevent the transformation of sodium benzoate into benzoic acid caused by
precipitation and reduce the effect of its use.
4. 1g benzoic acid is equivalent of 1.18g sodium benzoate and 1g sodium
benzoate is equivalent to 0.847g benzoic acid.
5. Benzoic acid in soy sauce, in soft drinks can be used together with p-
hydroxybenzoic acid esters and have efficiency.

Effect of Benzoic acid

1.Benzoic acid and sodium benzoate are commonly used food preservative. In
acidic conditions, it has inhibitory effect on yeast and mold. When pH value is
3 antibacterial strength, when pH was 6 for a lot of mould effect is very poor,
so the inhibition the optimum pH value is 2.5-4.0.
2.In the food industry with plastic barrels concentrated fruit and vegetable
juice, the maximum usage shall not exceed 2.0g/kg; in the jam (not including
canned), fruit juice (taste) drinks, soy sauce, vinegar in the maximum amount
is 1.0g/kg; in Wine, candy, wine in the maximum amount of 0.8g/kg in the low
salt; pickles, sauces, candied fruit, use the largest 0.5g/kg in carbonate; use
the largest beverage 0.2g/kg. because of solubility of benzoic acid, when used
will be stirring, or dissolved in a small amount of hot water or ethanol.
3.The use of concentrated fruit juice in the soft drink used for benzoic acid
easily volatile with steam, it is commonly used in the sodium salt. Benzoic
acid in food industry is a common preservative in dairy products, but not
allowed to be added. In general, benzoic acid is considered to be safe. But for
some special populations, including infants, long-term intake of benzoic acid
may lead to asthma, urticaria, metabolic acidosis and other adverse reactions.
4.Paul deodorant benzoic acid is also used as a beverage. As the cream sweet
perfume fragrance. Can also be used for chocolate, lemon, orange, sub berries,
nuts, candied fruit and other edible flavor type. Tobacco flavor also commonly
used. In addition of benzoic acid is also used as a pesticide, medicine, dye,
mordant and plasticizer agent for the production of raw materials, polyamide
resin and alkyd resin modifying agent and steel equipment anti rust agent.
