What is the function of food grade antioxidants?
Food grade antioxidants are products that inhibit free-radical oxidation of fats and oils. Oxidation of fats and oils produces off odors and flavors referred to as rancidity.
What types of food grade antioxidants does Eastman supply?
Eastman supplies Eastman Tenox™ BHA and Eastman Tenox™ TBHQ in pure form, as well as various combinations of these antioxidants in solution form (Eastman Tenox™ antioxidants). Many of the solutions contain citric acid as a chelating agent and acid synergist.
Which food grade antioxidants are best suited for general applications?
For general applications, Eastman Tenox™ TBHQ is the preferred antioxidant for vegetable fats and oils. Eastman Tenox™ BHA is effective in animal fats and butterfat. For specific applications, see Eastman publication ZG-262.
Why use Eastman Tenox™ antioxidants?
Eastman Tenox™ antioxidants are more soluble and/or dispersible in fats and oils; provide optimum ratios and combinations of antioxidants and citric acid for specific applications; and are easy to handle and weigh.
When is the optimum time to add antioxidants to food products?
Antioxidants should be added as early as possible. Once peroxides form in fats and oils, the inhibition effects of antioxidants decrease. Note that antioxidants only inhibit oxidation, not prevent it. Antioxidants cannot rejuvenate an oxidized product and are not a substitute for high quality raw materials and ingredients.
What is the function of Eastman Sustane™ SAIB food grade in beverages?
Eastman Sustane™ SAIB food grade (sucrose acetate isobutyrate) is a weighting agent used in citrus flavor emulsions, premixes, and syrups for producing carbonated or noncarbonated and alcoholic or nonalcoholic citrus beverages. Citrus-
flavored sport drinks and nutritional drinks also utilize Eastman Sustane™ SAIB.
Does Eastman Sustane™ SAIB have FDA approval?
Eastman Sustane™ SAIB, SAIB CO, and SAIB ET-10 food grade have FDA approval. Eastman Sustane SAIB enjoys the highest use level approved for any weighting agent (300 ppm in U.S. and Europe), thus giving formulators outstanding flexibility. Additionally, Eastman Sustane SAIB is approved by the joint Food and Agriculture Organization (FAO)/World Health Organization (WHO) expert committee (1996) for use in more than 20 countries and has an ADI (acceptable daily intake) of 20 mg/kg of body weight.
Why use Eastman Sustane™ SAIB instead of other commercial weighting agents?
Eastman Sustane™ SAIB (sucrose acetate isobutyrate) has almost no flavor effect at typical usage levels in beverages. It is very soluble in orange oil and has high oxidative stability. Eastman Sustane™ SAIB has undergone extensive safety testing on laboratory animals and humans. It metabolizes to sugar (sucrose), acetic acid, and isobutyric acid, all of which are safe, common components of foods.
How do you improve handling conditions of Eastman Sustane™ SAIB-SG?
Eastman Sustane™ SAIB CO and SAIB ET-10 are pourable at room temperature for easy handling. Eastman Sustane SAIB-FG (sucrose acetate isobutyrate) has a high viscosity at 30°C (100,000 cP), which makes handling difficult. As Eastman Sustane™ SAIB-FG is heated, the viscosity decreases to 8,000 cP at 50°C and 105 cP at 100°C. Therefore, it is recommended that Eastman Sustane SAIB-FG be heated to approximately 70°C to improve handling conditions.
What weighting agents are available from Eastman for use in beverages?
Eastman offers three food grade products for use as weighting agents in beverages; Eastman Sustane™ SAIB-FG (sucrose acetate isobutyrate), Eastman Sustane SAIB-CO (with a 10% blend of orange terpenes), and Eastman Sustane SAIB-ET-10 (which contains 10% ethanol).
