erythorbic acid in high pressure boiler

Dangerous Food Additives | People for Ethical Living

A manufactured fat created by forcing hydrogen gas into vegetable fats under extremely high pressure, an unintended effect of which is the creation of trans-fatty acids. Food processors like this fat because of its low cost and long shelf life. Found in margarine, pastries, frozen foods, cakes, cookies, crackers, soups, and nondairy creamers .

Effects of erythorbic acid on vitamin C metabolism in young

Erythorbic acid, an epimer of L-ascorbic acid, is used in the United States as a food additive. Studies were conducted to determine whether the ingestion of erythorbic acid in the diet had any beneficial or adverse effects on the human requirement for vitamin C. Young women were fed diets that contained controlled amounts of erythorbic acid and

QUIZ: Oxidation and Degradation Products Of Common Oxygen

Because of the alkalinity and sodium found in most boiler feedwater and boiler water, sulfite ion is the species found regardless of the initial salt. In the high temperature/pressure and alkaline atmosphere of the boiler, sodium sulfite will decompose. As a result, the sulfite salts are limited to pressures below 1250 psig. Na 2SO 3 + H 2O SO

Erythorbic acid | C6H8O6 - PubChem

Erythorbic acid's production and use as an antioxidant, especially in the brewing industry, may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 1.54X10-10 mm Hg at 25 °C indicates erythorbic acid will exist solely in the particulate phase in the atmosphere.
