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 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...

Biological preparation of ¹⁴C labeled aflatoxin

Creator:: Schoenhard, Grant Louis
Abstract:: Selected parameters that affect crude toxin production in both primary culture (growing cell culture) and resting culture were examined during efforts to produce sufficient crude toxin for purification. The parameters included carbohydrate and label source and concentration, cell concentration, incubation time and temperature and shaker speed. A higher yield of...

Efficacy of electrolyzed oxidizing (EO) water combined with UV-C light or gas exchange on sanitization of Jalapeno pepper using Serratia marcesens as surrogate for Salmonella

Creator:: Ekundayo, Olufunmilayo R.
Abstract:: Jalapeño peppers are usually consumed raw and fresh with minimal processing. They contain antioxidants and bioactive compounds which are of human health benefits. There have been an increasing number of reports of foodborne outbreaks attributed to inaccessibility of sanitizers to Salmonella , E.coli and Listeria monocytogenes when embedded in fruit...

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...

Flavor comparison of ultra high temperature processed milk heated by Ohmic heating and conventional methods

Creator:: He, Juan
Abstract:: Ultra high temperature (UHT) processing can extend shelf life of milk to several months without refrigeration, which is more convenient and energy saving than pasteurized milk. However, the poor acceptance caused by "cooked" flavors limits its marketing growth, especially in United States. Ohmic heating, which has a more uniform and...

[9,10-methylene-¹⁴C] sterculic acid metabolism in the rat : urinary metabolites, liver tissue distribution, and induced [omega]-hydroxylase activity

Creator:: Eisele, Thomas Anthony
Abstract:: Corn oil (CO) and Sterculic foetida oil (SFO) fed rats were injected with [9, 10-methylene-¹⁴C]sterculic acid. Less than 1% of the label was expired as carbon dioxide. The majority of the label was excreted in the urine as short-chain dicarboxylic acids with an intact cyclopropane ring. The major metabolites for...

Roles of microorganisms in the deterioriation of rockfish

Creator:: Lobben, J. C. and Lee, J. S.
Abstract:: Seven species of microorganisms indigenous to fish were inoculated into sterile fish muscle, obtained from Sebastodes alutus and Sebastalobus alascanus, and the production of total volatile acids (TVA) and total volatile bases (TVB) was determined during storage at 1 C. No production of TVA and TVB was noted in sterile...

Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

Creator:: Yuan, Fang
Abstract:: This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...
