Consuming science: A history of soft drinks in modern China

Yao, Liang 27 May 2016 (has links)
This dissertation investigates the development of the soft drink market in China from the late nineteenth century to the early twenty-first century, with particular attention to the rise of Coca-Cola. It examines how soft drinks competed with traditional Chinese summer food and beverage such as watermelons, herbal tea, plum juice, and nutriments which were believed to have medical properties for people’s summer health, and eventually became one of the most popular types of beverages in the country. Over one hundred years in the Chinese minds, soft drinks changed from an exotic but unsavory beverage to a popular drink and a symbol of modernity. This dissertation argues that western science competing with traditional Chinese medicine has been a driving force in shaping beverage consumption in modern China. There were constant politics played by the state, businesses, and consumers on production, marketing, and consumption of soft drinks, making a bottle of drink not merely a commodity but one that embodied science, modernity, and identity in Chinese society. Following the introduction chapter, chapter 2 of the dissertation delineates the clash between Chinese and western food culture in the late nineteenth century. It shows how traditional Chinese medicine (TCM) including the yin-yang theory and the concept of medicine-food homology played a role in shaping Chinese food culture for centuries. By analyzing advertisement, chapter 3 examines how soft drinks, which were considered by Chinese people as an unpleasant and unhealthy drink according to TCM, were marketed and gradually accepted as a hygienic and healthy drink under the rhetoric of modernization. Since foreign-brands such as Coca-Cola were luxuries, cheap imitations provided ordinary Chinese people, especially urbanites, opportunities to experience “modernity.” Chapter 4 discusses the culture of imitation in modern China in regard of soft drinks. In the first half of the twentieth century, consumption were politicized in National Products Movements, in which soft drink brands were categorized into either Chinese or foreign and people’s loyalty to the nation was, to some extent, judged by their brand choice. However, there was something far more than nationalism that played a role in the picture. Taking the Shanghai Coca-Cola protest of 1947 as a case study, chapter 5 reveals that Chinese nationalism in National Products Movements in the late forties was used by Chinese businessmen to advance themselves in business competition. When political conflicts became a major theme in Maoist China, Coca-Cola was criticized as a symbol of imperialism and driven out of China. Nevertheless, science-driven consumption did not fade away. Chapter 6 shows that instead of promoting Coca-Cola, the People’s Republic of China “invented” salty soda as a prevention and treatment of heat stroke and widely distributed it among workers as a socialist welfare in summer. The final chapter discusses the return of Coca-Cola in the post-Mao era. It shows that science and modernity was a consistent subject in production and consumption in China, where the state promoted it cautiously due to political sensibility while ordinary Chinese people embraced it enthusiastically with little resistance.

Erosive cola-based drinks affect the bonding to enamel surface: an in vitro study

Casas-Apayco, Leslie, Dreibi, Vanessa Manzini, Hipólito, Ana Carolina, Graeff, Márcia Sirlene Zardin, Rios, Daniela, Magalhaes, Ana Carolina, Buzalaf, Marília Afonso Rabelo, Wang, Linda 04 August 2014 (has links)
Objective: This study aimed to assess the impact of in vitro erosion provoked by different cola-based drinks (Coke types), associated or not with toothbrushing, to bonding to enamel. Material and methods: Forty-six bovine enamel specimens were prepared and randomly assigned into seven groups (N=8): C- Control (neither eroded nor abraded), ERO-RC: 3x/1-minute immersion in Regular Coke (RC), ERO-LC: 3x/1-minute immersion in Light Coke (LC), ERO-ZC: 3x/1-minute immersion in Zero Coke (ZC) and three other eroded groups, subsequently abraded for 1-minute toothbrushing (EROAB-RC, EROAB-LC and EROAB-ZC, respectively). After challenges, they were stored overnight in artificial saliva for a total of 24 hours and restored with Adper Single Bond 2/Filtek Z350. Buildup coronal surfaces were cut in 1 mm2-specimens and subjected to a microtensile test. Data were statistically analyzed by two-way ANOVA/Bonferroni tests (a=0.05). Failure modes were assessed by optical microscopy (X40). The Interface of the restorations were observed using Confocal Laser Scanning Microscopy (CLSM). Results: All tested cola-based drinks significantly reduced the bond strength, which was also observed in the analyses of interfaces. Toothbrushing did not have any impact on the bond strength. CLSM showed that except for Zero Coke, all eroded specimens resulted in irregular hybrid layer formation. Conclusions: All cola-based drinks reduced the bond strength. Different patterns of hybrid layers were obtained revealing their impact, except for ZC. / This study was supported in part by grants given by the São Paulo Research Foundation (FAPESP), Process no. 2009/14986-0, and the National Council for Scientific and Technological Development (CNPq), Process no. 480038/2007-4.

A study to determine the relationship between sugar-sweetened beverages and BMI in preadolescents (11-13 years)

Zielinski, Victoria A. 05 May 2012 (has links)
The purpose of this study was to determine the relationship between sugar-sweetened beverage consumption of sixth and seventh graders (ages 11 to 13) and its effect on BMI. The variables that the researcher examined were the types and amounts of sugarsweetened beverages consumed, and gender in children attending a Region 10 middle school in Burlington, Connecticut. There were six hypotheses examined in this study. The sample consisted of 61 subjects attending Har-Bur Middle School in Burlington, CT. The current investigator modified the Block Kids Food Frequency Questionnaire (Appendix D) by adding additional questions to the original Block Kids FFQ regarding sugar-sweetened beverages that were not measured on the original FFQ. Results of the study did not show statistically significant differences for any of the hypotheses regarding sugar-sweetened beverages and BMI (p > .05). However, there were tendencies for sugarsweetened beverage consumption to decrease as preadolescents aged. Also for each additional ounce of fruit drinks consumed there were increases in BMI. Further research needs to be conducted to determine the full extent of the effects of sugar-sweetened beverages on BMI in preadolescents. / Department of Family and Consumer Sciences

Využití náhradních sladidel v nealkoholických nápojích a jejich vliv na senzorickou jakost

WEISSOVÁ, Denisa January 2017 (has links)
The subject of this thesis was to evaluate the use of sweeteners in a selected group of soft drinks from the viewpoint of the sensory quality. Using selected methods of sensory analysis were evaluated four samples of soft drinks with lemon flavor. The first sample A - Sprite contained aspartame, acesulfame K and fructose - glucose syrup. The second sample B - Slice consisted of the aspartame and acesulfame Ksweeteners. Sample C - Lemon contained only sugar and last sample D - Santerre, was composed of aspartame, acesulfame K and sodium saccharin. The evaluators were divided into two groups according to age. The first group of respondents was composed of students from the University of South Bohemia in the age of 18-27 years. The second group was composed of randomly selected people aged 40+. The aim of the thesis was to determine whether there is a disparity between the groups. Top rated sample became the sample A - Sprite. Differences occurred in sample B and C. Sample B which contains aspartame and acesulfame K was preferably evaluated bythe first group, whereas the second group consisting of older respondents evaluated preferably sample C Lemon. Lemon sample contains only sugar and its taste is therefore less noticeable or even perceived as without flavour, based on the evaluated results.The lowest rated sample was unambiguously sample D, which contains sweetener aspartame, acesulfame K and sodium saccharin. Part of this work was a questionnaire for consumers.Its main aim was to find out what mostly influences respondents when buying soft drinks, what attitude artificial sweeteners they have and if they find the composition of soft drinks determinative.

Devido ao elevado teor de açúcar neste produto e ao baixo pH, os refrigerantes tornam-se propícios ao desenvolvimento de microrganismos, em especial as leveduras. A contaminação microbiológica é mais comum na etapa de produção, entretanto, a maioria dos contaminantes pode ser proveniente de matérias-primas como água ou equipamentos quando não higienizados de maneira adequada. De acordo com o histórico de análises microbiológicas da Indústria BEBIDAS POTY Ltda, foram detectados alguns pontos de contaminação por leveduras dentro do fluxograma de produção, as quais têm apresentado certa resistência aos sanificantes utilizados. Desta forma o presente trabalho teve como objetivo isolar, identificar leveduras de matérias primas e diversos equipamentos da produção e avaliar o efeito inibitório dos sanificantes nas leveduras isoladas, buscando conhecer a eficácia dessas preparações. Neste estudo, foram isoladas 26 leveduras apenas da água de enxágue após o processo de higienização dos equipamentos de produção em todas as linhas de produtos carbonatados. Dentre as leveduras isoladas, os gêneros mais comuns foram Candida tropicalis, C. orthopsilosis, C. viswanathii, C. boidinii, Pichia manshurica, Zygosaccharomyces bisporus, sendo a espécie C. sojae a mais frequente. Os isolados foram testados na presença de 1) detergente alcalino clorado, 2) detergente alcalino não clorado, 3) desinfetante ácido peracético e 4) base ácida com ação de detergência/desinfetante de duas marcas comerciais identificadas como Marca I e Marca II, na perspectiva de encontrar a concentração mínima inibitória. Os agentes químicos de basicidade elevada com ação de limpeza foram os mais eficientes nos testes de inibição/crescimento e o menos eficazes foram os detergentes alcalinos contendo cloro sendo necessária a utilização de concentrações muito elevadas para atingir a concentração mínima inibitória. Os agentes químicos com ação de desinfecção demonstraram que as leveduras, foram muito sensíveis para os ácidos fortes oxidantes como o nítrico, peracético e gás O3. / Soft drinks are carbonated beverages, obtained by diluting the juice or vegetable extract in drinking water, added of sugars. Because of the high sugar content of this product and the low pH, the refrigerants are susceptible to development of microorganisms, in particular yeasts. Microbial contamination is most common in the production step, however, most of the contaminants can come from raw materials and equipment such as water when not cleaned properly. According to the history of microbiological analyzes of Industry DRINKS POTY Ltda, some points of contamination by yeasts were detected within the production flow chart, which have shown some resistance to the sanitizers used. Thus, the present study aims to isolate and identify yeast from raw materials and from various equipment and evaluate the inhibitory effect of sanitizers on yeasts. It was isolated 26 yeasts strains from rinse water after the process of cleaning production equipment in all lines of carbonated products. Among the yeasts, the most common genera were Candida tropicalis. C. orthopsilosis, C. viswanathii, C. boidinii, Pichia manshurica, Zygosaccharomyces bisporus, the most frequent species was C. sojae. The isolates were tested in the presence of 1) chlorinated alkaline detergent, 2) alkaline detergent non-chlorinated, 3) disinfectant peracetic acid and 4) acid based detergent with disinfectant action two trademarks identified as Marca I and Marca II with a view to find the minimum inhibitory concentration. Chemical agents with high alkalinity were the most efficient in inhibition of yeast growth the less effective was alkali detergent containing chlorine being necessary to use very high concentrations to achieve the minimum inhibitory action. The data showed that the yeasts were very sensitive, to oxidizers such as nitric acid, peracetic acid and O3 gas.
