The potato : composition, non-enzymatic browning and anthocyanins

Creator:: Rodriguez-Saona, Luis Enrique
Abstract:: Chipping varieties and model systems were used to determine the role of potato constituents on chip color. Composition was evaluated by HPLC and chip color measured using a ColorQuest colorimeter. Reducing sugar (RS) content did not completely explain color quality when present in low concentrations (<60 mg/lOOg). Levels of ascorbic...

Radish anthocyanin extract as a natural red colorant for maraschino cherries

Creator:: Hundskopf, Maria Monica Giusti
Abstract:: Red radish anthocyanin extract (RAE) was investigated for coloring brined cherries as an alternative to FD&C Red No. 40. Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone, partitioned with chloroform, and isolated using C-18 resin. The monomeric anthocyanin content was determined by...

Structure and conformation of red radish (Raphanus sativus L.) anthocyanins and their effect on color and pigment stability

Creator:: Giusti Hundskopf, Maria Monica
Abstract:: Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone and chloroform and isolated using C-18 resin. Chemical structure and conformation of major pigments were elucidated by 1-D and 2-D NMR, Mass Spectroscopy, HPLC, and spectral analyses. Two novel di-acylated anthocyanins, pelargonidin 3-0-[2-0-(β-D-glucopyranosyl)-(6-0- trans-p-coumaroyl-...

Diethylnitrosamine, ethylnitrosourea, and dimethylbenz(a)anthracene DNA binding studies in the rainbow trout

Creator:: Van Winkle, Samina
Abstract:: Dimethylbenz (a) anthracene (EMBA), a carcinogen that requires metabolic activation to produce active metabolites capable of binding to DNA, has been studied in the trout and other fish. Polycyclic aromatic hydrocarbons (PAH) are of importance as they are ubiquitous in the environment and their carcinogenic effects in fish from contaminated...

Effects of the anticarcinogen indole-3-carbinol on Xenobiotic metabolizing enzymes in rainbow trout

Creator:: Swanson, Hollie I.
Abstract:: Indole-3-carbinol (I3C) inhibits chemically induced tumor formation in rodents and rainbow trout. This study examines the effect of I3C and its analog, indole-3-acetonitrile (I3N) on xenobiotic-metabolizing enzyme systems. The modulation of these enzyme systems have been shown to have significant effects on the interaction of chemical carcinogens and cellular constituents....

The significance of glutathione conjugation for aflatoxin B₁ metabolism in rainbow trout and coho salmon

Creator:: Valsta, Liisa M.
Abstract:: In rodent models as well as in fish models there are significant species differences in the susceptibility toward aflatoxin B₁ (AFB₁) carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis than rat. Researchers have come to the conclusion that the lower susceptibility of mice is not a result of less effective...

Mechanisms of action by some inhibitors of aflatoxin B₁ carcinogenesis in rainbow trout

Creator:: Goeger, Douglas Eugene
Abstract:: Indole-3-carbinol (I3C) and butylated hydroxyanisole (BHA), anti-carcinogens present in the human diet, were tested for their in vivo and in vitro effect on aflatoxin B₁. (AFB₁) metabolism, and DNA adduct formation in the rainbow trout. Dietary BHA at either 0.3 or 0.03% had no effect on the hepatic tumor incidence...

Ras oncogenes and p53 suppressor genes in fish carcinogenesis models

Creator:: Cheng, Ronshan
Abstract:: A digoxigenin-labeled nonradioactive detection system was used to screen a zebrafish cDNA library for p53-like and ras-like genes. One clone was isolated and identified as an incomplete p53-like gene. The insert size of this clone is 1777 bp, which encodes part of evolutionarily conserved region II and all of regions...

Strawberry wine color quality : influence of variety, maturity and mold contamination

Creator:: Pilando, Leticia S.
Abstract:: This study was conducted to evaluate the influence of maturity, mold contamination and variety on the color quality of strawberry wines. Indices for acceptability were determined using instrumental measurements and sensory analysis. Compositional analyses were done on the fully ripe and overripe Benton and Totem strawberries. Included were anthocyanin content,...
