This dissertation analyzes the travel writings of Isabella Bird Bishop, Mary Kingsley, Florence Douglas Dixie, and Isabel Savory. While away from England, these women writers participated in cultural exchanges which led to reevaluations of British womanhood. British women travel writers operated not only within the power structures of gender but also within the structures of empire, class, and race. Women travel writers blazed the trail for the New Woman of the end of the century. Before cycling and cigarette smoking were allowed, daring women such as Isabella Bird Bishop and Mary Kingsley crisscrossed the globe in defiance of patriarchal tradition and in search of their own pleasure --- later both hallmarks of the New Woman. Contrary to conservative hopes, women travel writers increased in popularity, inspired young women to be daring and challenged the Victorian status quo by writing of the dangerous pleasures they experienced while abroad. As inspiration for the New Women, women travel writers reveled in danger and athletics, and in time, reshaped England's image of womanhood. Because of the positive accounts of athleticism provided by women travelers, female health became a prominent topic in society. By the early twentieth century, women had increased access and acceptability to physical pursuits.

Master of Science / Department of Grain Science and Industry / Sajid Alavi / Extrusion processing and frying are the two most commonly used methods to produce savory snacks. These snacks are mostly starch based and also contain high amounts of fat. Snacking percentage has increased drastically over the past few decades causing many health problems like obesity, hypertension and cardiovascular diseases. The overall objective of this study was to develop novel soy based savory snack that are high in protein and has less fat using both extrusion processing and frying. In the first part of this study both defatted soy (25-75%), wheat flour, monoglycerides (0.375 & 0.75%) and sodium bicarbonate (0 and 0.5%) were used to produce dense extrudates, which mimic the shape of lentils using pilot scale twin screw extruder. The extrudates were soaked in water and fried in corn oil to produced savory snacks. Soy influenced the water absorption during soaking and oil uptake during frying. The water uptake and % fat decreased with increase in soy and the amount of water uptake influenced the % fat absorption in the product. No significant differences were observed in overall acceptability and to summarize the increased protein and dense structure of the products challenge the texture of the products. In the second part of this research, dynamics of water and oil uptake were studied to see the role of texture modifiers like soy protein isolate (4, 8, & 12%), calcium bicarbonate (0.2, 0.4 & 0.6%) and pregelatinized wheat starch (4, 8, & 12%) on texture, water and oil uptake. Descriptive sensory analysis was conducted to study the sensory attributes of the products. Water holding capacity is influenced by the level of % starch addition and the degree of starch degradation during processing. Oil uptakes correlates to that of WHC and is also affected by the degree of gelatinization and crust formation. Degree of starch gelatinization, oil uptake and oil and starch matrix interactions had an impact on hardness. Among SPI, CaCO3 and PGWS, PGWS lowered the product hardness followed by SPI and CaCO3. Descriptive sensory results are similar to experimental results with PGWS samples having lower initial or substantial hardness and more oxidized or heated oil aroma and flavor.

<p>Kombuha je tradicionalni napitak koji se dobija fermentacijom zaslađenog crnog<br />ili zelenog čaja, fiziolo&scaron;kom aktivno&scaron;ću čajne gljive, koja predstavlja simbiozu<br />autohthonih vrsta kvasaca i bakterija sirćetnog vrenja. Cilj rada je bio da se ispita<br />biolo&scaron;ka aktivnost konzumnih kombuha napitaka (titrabilne kiselosti 3,5-4 g/L) od<br />crnog čaja (<em>Camellia sinensis</em> L), čaja ehinacee (<em>Echinacea purpurea</em> L.) i<br />rtanjskog čaja (<em>Satureja montana</em> L.). Za ispitivanje antimikrobne aktivnosti<br />kombuha napitaka upotrebljeni su sledeći sojevi bakterija, kvasaca i plesni:<br /><em>Pseudomonas aeruginosa</em>, <em>Staphylococcus aureus</em>, <em>Bacillus sp.</em>, <em>Salmonella<br />enteritidis, Proteus mirabilis, Escherichia coli, Sarcina lutea, Saccharomyces<br />cerevisiae, Candida pseudotropicalis, Rhodotorula sp., Penicillium<br />aurantiogriseum, Aspergillus niger i Aspergillus flavus</em>. Antioksidativna aktivnost<br />kombuha napitaka ispitana je na DPPH i OH radikale ESR spektralnom metodom.<br />Antiproliferativna aktivnost čajeva i kombuha napitaka od crnog i rtanjskog čaja<br />ispitana na tri ćelijske linije humanih karcinoma: HeLa (epitelni karcinom<br />cerviksa), MCF-7 (adenokarcinom dojke) i HT-29 (adenokarcinom debelog<br />creva). Pored istraživanja biolo&scaron;ke aktivnosti kombuha napitaka, cilj rada je bio da<br />se ispitaju i neki od osnovnih parametara kombuha fermentacije &ndash; optimalna<br />količina izvora ugljenika i azota u medijumu za kultivaciju, geometrijske<br />karakteristike fermentora, inokulacija starter kulturama. Definisanje kritičnih<br />parametara kombuha fermentacije je bio osnov za izvođenje matematičkog<br />modela za scale-up fermentativnog procesa.</p> / <p>Kombucha is a traditional beverage obtained by fermenting sweetned black or<br />green tea with tea fungus, which represents a symbiotic combination of acetic acid<br />bacteria and autochthonous yeast species. In this study, the antimicrobial,<br />antioxidative and antiproliferative activity of kombucha beverages (titratable<br />acidity 3,5-4 g/L) obtain from black tea (<em>Camellia sinensis</em> L), echinacea tea<br />(<em>Echinacea purpurea</em> L.) and rtanj tea (<em>Satureja montana</em> L.) were tested.<br /><em>Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus sp., Salmonella<br />enteritidis, Proteus mirabilis, Escherichia coli, Sarcina lutea, Saccharomyces<br />cerevisiae, Candida pseudotropicalis, Rhodotorula sp., Penicillium<br />aurantiogriseum, Aspergillus niger i Aspergillus flavus</em> were used as test<br />microorganisms for examination of antimicrobial activity. The antioxidant activity<br />of differently prepared kombucha beverages was examined agains DPPH and OH<br />radicals by ESR-spectrometry. Antiproliferative activity of black tea kombucha<br />and Satureja montana kokmbucka was measured by sulforhodamine B<br />colorimetric assay on HeLa (cervix epitheloid carcinoma), HT-29 (colon<br />adenocarcinoma), and MCF-7 (breast adenocarcinoma) cells line. Also, same<br />parametars of kombucha fermentation &ndash; optimal quantity of source of carbon and<br />nitrogen in cultivation medium, geometric characteristics of reactors and<br />inoculation by starter culture &ndash; were tested. Definition of critical parameters of<br />kombucha fermentation is important for derivation of mathematical model for<br />scaling-up fermentation process.</p>
