Pengawet yang banyak dijual dipasar

Pengawet yang banyak dijual dipasaran dan digunakan untuk mengawetkan berbagai bahan makanan adalah benzoat, dengan rumus kimia C₇H₅NaO₂ yang biasanya terdapat dalam bentuk natrium benzoat atau kalium benzoat karena lebih mudah larut. Natrium benzoat berwarna putih, granula tanpa bau, bubuk kristal atau serpihan dan lebih larut dalam air dibandingkan asam benzoat dan juga dapat larut dalam alkohol, jadi garam natrium lebih sering digunakan dari asam benzoat karena sifatnya tersebut. Benzoat sering digunakan untuk mengawetkan berbagai makanan dan minuman seperti sari buah, minuman ringan, saus tomat, saus sambal, selai, jeli, manisan, kecap dan lain-lain.
Selain berfungsi sebagai bahan pengawet, asam benzoat juga berperan sebagai antioksidan karena pada umumnya antioksidan mengandung struktur inti yang sama, yaitu mengandung cincin benzen tidak jenuh disertai dengan gugus hidroksil atau gugus amina. Antioksidan dapat menghambat setiap tahap proses oksidasi, dengan penambahan antioksidan maka energi persenyawaan aktif ditampung oleh antioksidan sehingga reaksi oksidasi berhenti. Penambahan antioksidan buatan dalam bahan makanan harus lebih hati-hati, karena banyak diantaranya yang menyebabkan keracunan pada dosis tertentu, dosis yang diizinkan dalam bahan pangan adalah 0,01-0,1% . (Tranggono, 1990)
Berdasarkan Peraturan Menteri Kesehatan RI No.722/Menkes/Per/IX/1988, batas penggunaan maksimum natrium benzoat yang diizinkan pada produk minuman yaitu 600 mg/kg. (Depkes, 1999)

Preservatives that are sold over the counter and is used to preserve a variety of foodstuffs is benzoic, with chemical formula C H ₇ ₅ NaO ₂ are usually in the form of sodium benzoate or potassium benzoate because it dissolves more easily. Sodium benzoate is a white, odorless powder, granule of crystals or flakes and more soluble in water than benzoic acid and can also dissolve in alcohol, so the more commonly used sodium salt of benzoic acid because of its nature. Benzoate is often used to preserve various foods and beverages such as fruit juice, soft drinks, tomato sauce, chilli sauce, jams, jellies, preserves, soy sauce and others. In addition to functioning as a preservative, benzoic acid also acts as an antioxidant antioxidants because in general contain the same core structure, i.e. contain no saturated ring instructor accompanied with hydroxyl or amine functional groups. Antioxidants may inhibit the oxidation process, each stage with the addition of antioxidant active compounds energy then accommodated by antioxidants so that oxidation reactions stop. The addition of artificial antioxidants in foodstuffs should be more careful, because many of them which cause poisoning in certain doses, doses are permitted in foodstuffs is 0.01-0.1%. (Tranggono, 1990) Based on the regulation of the Minister of health RI No. 722/Menkes/Per/IX/1988, the use of sodium benzoate is the maximum limit allowed on beverage products namely 600 mg/kg. (Health, 1999)

In addition to functioning as a preservative, benzoic acid also acts as an antioxidant because generally antioxidants contains the same core structure, which contains a benzene ring unsaturated accompanied with hydroxyl or amine group. Antioxidants can inhibit oxidation every stage of the process, with the addition of the antioxidant compounds active energy stored by antioxidants that stop the oxidation reaction. The addition of artificial antioxidants in foodstuffs should be more careful, because many of them cause poisoning in certain doses, doses that are allowed in foodstuffs is 0.01-0.1%.
