The effect of erythorbic acid on the determination of ascorbic acid levels in selected foods by high performance liquid chromatography and spectrophotometry

Creator:: Tuan, Shenhsiu
Abstract:: A high performance liquid chromatography (HPLC) procedure using a LiChrosorb-NH₂ column and a eluant buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH 5.95, was developed for the successful separation and determination of ascorbic and erythorbic acids in selected food samples. Application of the method, which is sensitive, rapid and...

The role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate. The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...

The stability of ascorbic acid in bottled cranberry-based beverages under home-use conditions

Creator:: Wong, Geoffrey K.
Abstract:: Commercially bottled, vitamin C-fortified, cranberry juice cocktail and cranberry-apple (cranapple) juice drinks were stored at 5°C under simulated home-use conditions. Ascorbic acid (AA) and dehydroascorbic acid (DHA) levels were evaluated over a period of seven days by high performance liquid chromatography (HPLC). Total vitamin C content was also determined by...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

Influence of ascorbic acid supplementation on copper status in young adult men

Creator:: Finley, Elizabeth Bidwell
Abstract:: Thirteen healthy adult males, ages 20-40, consuming self selected diets, were given instructions to take one 500 mg tablet of ascorbic acid three times a day with their meals for a period of ten weeks. The effect of this daily supplementation on copper status was investigated. An estimation made from...

Gel electrophoretic analysis of the protein changes in ground beef stored at 2⁰C

Creator:: Xiong, Youling
Abstract:: A study was completed to determine the extent of the protein changes occurring in ground beef stored at 2°C for 10 days. Sections of semitendinosus muscle were obtained immediately after the slaughter of three beef animals. Each section was divided into two equal portions, one of which was ground and...
