Impacts of low-water activity food type on inactivation kinetics and models of foodborne pathogens treated with low-temperature, vacuum-assisted steam processing

Acuff, Jennifer Claire 29 April 2020 (has links)
Low water activity foods (LWAF), specifically nuts and dried fruits, have been generally considered safe because they do not support the growth of foodborne pathogens. However, many pathogens have been noted to survive in LWAF for considerable periods of time, and a number of recent outbreaks and recalls have implicated various types of nuts and dried fruits. The Food Safety Modernization Act requires food processors to develop preventive control plans that make ready-to-eat LWAF safer for consumers. The presented research was designed to investigate several aspects of LWAF safety by evaluating a steam process as a strategy to remove pathogen contamination from LWAF, modeling the inactivation of such treatments, and studying the thermal resistances of two E. coli strains in low-water activity solutions. Low-temperature, vacuum-assisted steam (vacuum-steam) was evaluated as a potential intervention and preventive control to remove pathogens from the surface of LWAF without using high-heat treatments that could damage product quality. The presented work examined the efficacy of vacuum-steam (<85°C) as a means to decontaminate the surface of whole macadamia nuts, dried apricot halves, and raisins from Salmonella spp., Listeria monocytogenes, and Shiga toxin-producing Escherichia coli (STEC) contamination. The low-temperature steam treatments successfully reduced all pathogens by >4 log CFU/g from the surfaces of the foods. Additionally, Pediococcus acidilactici, proved to be a surrogate organism for these pathogens and could be used to challenge and validate similar treatments within processing plants. The data were fit to models, which showed that food type significantly impacted the fit, with the Weibull model best describing bacterial inactivation kinetics on raisins and macadamia nuts, and the Gompertz model best describing reductions on the apricot halves. The models were challenged for validation of their abilities to predict times required for 3-log reductions using internal and external datasets, determining the usefulness to industry members who wish to design similar thermal treatments for LWAF. Comparing predicted values from internally constructed models to observed values generated from external data, models were shown to be limited in scope and application and could only be applied to pathogen inactivation on different LWAF or thermal processes in certain circumstances. First-order and Weibull model predictions of bacterial reductions on dried apricots had varied success in predicting times for 3-log reductions on other thermally treated LWAF. However, the models of bacterial reductions on thermally treated macadamia nuts frequently overestimated the times required for 3-log bacterial reductions for other LWAF. In an effort to understand the effect that reduced water activity has specifically on STEC, two strains were investigated for induced thermal resistance due to osmotic stress. Thermal resistance of STEC strains (O121:H19 and O157:H7) were evaluated on the basis of strain variation, culture preparation, and water activity (D- and z-values). At the lowest treatment temperature (56°C), O121 displayed greater heat resistance than O157, and the broth-grown samples exhibited greater heat resistance than the lawn-grown cells, but significant differences were not observed at higher temperatures. Samples in reduced-water activity solutions displayed reduced thermal resistance at 56°C, but the z-values were 29-43% higher than those of high-water activity samples. While water activity has been shown to impact thermal resistance of pathogens, comparisons of STEC thermal resistance according to the D- and z-values revealed that other factors also play roles in pathogen thermal resistance on LWAF. Results from the collection of experiments conclude that efficacy of thermal treatments is impacted by the physiological state of the cells, stress experienced in the food matrix, and characteristics of the food, including water activity and composition. / Doctor of Philosophy / Consumers expect foods they purchase to be safe to consume by themselves and family members, particularly those that are ready-to-eat with no additional cooking requirements. Many of these foods are low-water activity foods (LWAF), like nuts and dried fruits, with very little water content that could be used by bacteria. These foods may be preferred snack foods due to their affordability, long shelf lives, and health benefits over other types of snack foods. Until recently, LWAF were generally considered safe because they do not support the growth of foodborne pathogens due to the lack of moisture or water within the food. However, a number of recent outbreaks related to various types of nuts and dried fruits have proven that many pathogens can survive in dried foods, even if not actively growing, for considerable amounts of time. Designed to address these types of food safety issues, the Food Safety Modernization Act recognizes risks associated with foods and responded with regulations requiring food processors to take steps to make ready-to-eat LWAF, like nuts and dried fruits, safer for consumers. A popular strategy is to treat foods with heat to destroy pathogens, however the quality attributes of some nuts and dried fruits could be damaged by high-heat treatments like roasting. An alternative process uses a vacuum to form steam at lower temperatures, allowing for efficient heat transfer through water droplets to the surface of the foods, thus causing less damage to the foods without introducing too much moisture. This research evaluated how this process could be used by food processors to remove harmful bacteria from the surfaces of whole macadamia nuts, dried apricot halves, and raisins. Results indicated that the low-temperature steam treatments successfully reduced Salmonella, Listeria monocytogenes, and Shiga toxin-producing Escherichia coli (STEC) by >4 log CFU/g (>99.99%) from the surfaces of the foods. Additionally, a nonpathogenic lactic acid bacterium, Pediococcus acidilactici, exhibited similar or greater heat tolerance, which would allow food processors to use it as a substitute, or surrogate, for in-plant studies without introducing harmful bacteria into the food processing environment. Mathematical models were used to describe the trends of bacterial death due to the steam treatments, and the results indicated that the type of food significantly impacted the reduction of bacteria. The models were tested using additional data collected within our own laboratory, as well as others. Results indicated that some of the models could be used as predictors of bacterial death for similar LWAF but can only be applied with caution and consideration for the type of food and process. Additionally, two different E. coli strains associated with outbreaks (O121:H19 and O157:H7) were investigated to understand impacts of strain variation, growth method, and water activity on thermal resistance. Some differences in heat resistance were observed between the strains and between the growth methods. Additionally, the reduced water activity seemed to decrease the bacteria's ability to withstand some heat treatments. Overall, thermal resistance studies indicated that several factors, in addition to water activity, impact pathogens' development of resistance to heat treatments. The experiments' results show that there are complex relationships between bacteria and the food they inhabit. Food processors must consider these relationships in order to design the best thermal processes to make LWAF safe for consumers.

Efeito da suplementação com castanha-do-brasil (Bertholletia excelsa, H.B.K.) no estado nutricional de praticantes de capoeira em relação ao selênio / Effect of supplementation with Brazilian nuts (Bertholletia excelsa, H.B.K.) in the nutritional status of Selenium and it\'s activity in young adult capoeira players

Coutinho, Vanessa Fernandes 10 September 2003 (has links)
O objetivo deste estudo foi estabelecer uma correlação entre o efeito da suplementação por meio da ingestão de castanhas-do-brasil (CS) com o estado nutricional de praticantes de capoeira em relação ao selênio (Se). A importância deste micronutriente foi evidenciada pela sua participação no sistema de proteção antioxidante, justificada pela incorporação de Se na glutationa peroxidase (E. C. 1.11.1.9). Esta enzima catalisa a redução de hidroperóxidos e facilita a conversão de H2O2, protegendo o organismo contra o dano oxidativo, e outros efeitos prejudiciais das espécies reativas de oxigênio (ROS). A atividade física proporciona um aumento no consumo de O2 e consequentemente maior produção de ROS, provocando estresse oxidativo. A pesquisa foi composta por 29 capoeiristas, residentes em São Paulo, com idade média de 21 anos para mulheres, e 24 para homens. O período médio de treinamento foi de 3,51 por semana e a duração de cada treinamento em média, foi de 109 minutes. O consumo médio de oxigênio (VO2 Máx.) foi de 41 ml/kg/min para as mulheres, e 48mllkg/min para os homens. A classificação do estado nutricional dos capoeiristas, de acordo com seu IMC foi normal (Organização Mundial de Saúde, 1995). Antes da suplementação, a ingestão usual de Se dos capoeiristas foi insatisfatória de acordo com a EAR e RDA. A concentração de Se no plasma e eritrócito aumentou depois da suplementação com CS (p<0,05), mas não houve correlação com o sexo dos participantes. A atividade enzimática da GPx também aumentou após a suplementação (p<0,05), demonstrando que a enzima é um sensível indicador do estado nutricional de Se, e não houve correlação em relação ao sexo dos participantes. Os resultados sugerem uma correlação positiva entre o efeito da suplementacão com CS e a concentração de Se e da atividade da enzima GPx (p< 0,05; R=0,72 para o plasma and R=85 para o eritrócito). / The purpose of this study was to establish a correlation between the effect of supplementation with Brazilian nuts (BN) with the nutritional status of Se and it\'s activity in young adult capoeira players. The biological importance of this oligoelement was evident by the participation in the \"antioxidant protection system\". It\'s antioxidant role is justified by its incorporation, as selenium, in the peroxidase glutathione (E.C. 1.11.1.9). This enzyme catalyzes the reduction of organic hidroperoxides and facilitates the conversion of H2O2 protecting the organism against the oxidative damage, and other harmful effects of \"reactive oxygen species\" (ROS). The physical activity causes an increase in consumption of O2 and consequently high production of ROS, causing oxidative stress. The population has composed of 29 capoeira players resident in São Paulo, with a mean age of 21 women and 24 for men. The average training period was 3,51 per week and the duration of each training period was 109,46 minutes. The average oxygen consumption (VO2 Máx., ml/kg/min) was 41 for women and 48 for men. Nutritional status classification of the capoeira players (cap) according with World Health Organization (WHO): IMC (1995) was normal. Before supplementation the usual diet was unsatisfactory for selenium according to EAR and RDA (2000). The Se concentration of the plasma and erythrocyte increased after supplementation with Brazilian nuts (p< 0,05), but didn\'t correlated with the sex of the participants. GSH-Px enzymatic activity also increased after this supplementation (p< 0,05), showing that this enzyme is a sensitive marker of nutritional status of Se. Also we didn\'t found correlation with the sex of the participants. The results suggest a positive correlation between the effect of supplementation with BN and Se concentrations and the activity of the GSH-Px enzyme (p< 0,05; R=0,72 for the plasma and R=85 for the erythrocyte).

Maillages administratifs et gestion du territoire en Bulgarie, une lecture géographique

Boulineau, Emmanuelle 04 December 2003 (has links) (PDF)
On s'interroge dans cette thèse sur la capacité de l'État bulgare à ordonner et à produire le territoire par les maillages administratifs. Trois champs problématiques sont explorés. Le premier concerne la crise de l'État, elle prend en Bulgarie une acuité particulière dans le contexte de transition post-socialiste. L'interaction entre l'Orient et l'Occident et l'importation du modèle de l'État-nation constituent le deuxième axe d'analyse. Enfin, la convergence avec le " modèle " européen de gestion territoriale, dans la perspective de l'adhésion à l'UE, permet d'explorer les rapports entre le politique et le territoire. Comment la logique territoriale de l'État moderne et de la politique européenne s'articule-t-elle avec le fonctionnement réticulaire balkanique ? La première partie analyse les réformes administratives post-socialistes. La deuxième partie étudie la construction de l'État-nation bulgare. La troisième partie appréhende les recompositions territoriales en cours.

No. of bitstreams: 1 Fernandes DC 2011.pdf: 372122 bytes, checksum: e2a86ba2aff621dd5ddc47d727122a8d (MD5) Previous issue date: 2011-03-28 / The aim of this study was to evaluate the effect of the intake of baru almond, peanut and brazil nut in lipid profile and in lipid peroxidation in rats that were fed with high-fat diet. The effect of baru almond, peanut and brazil nut intakes in lipid profile and in lipid peroxidation were evaluated by bioassay with young adults Wistar rats during two months. The diets were formulated according to American Institute of Nutrition (AIN-93G): 5 fat diets (0.1% cholic acid + 1% cholesterol + 5% lard + 15% of one the fat sources lard and olive oil [controls], baru almond, peanut or brazil nut) and a standard diet (7% soybean oil). Blood samples were collected in order to determine the serum lipid profile and the samples of the animal liver were collected in order to evaluate total malondialdehyde (total MDA), reduced glutathione and vitamin E. Peanut modulated the lipid profile in rats with high-fat diet, decreasing levels of total cholesterol (TC= 84 mg.dL-1) and triglycerides (TG= 46 mg.dL-1), and increased levels of HDL-cholesterol (HDL-c= 44 mg.dL-1), when compared to lard-control (TC= 217 mg.dL-1, TG= 223 mg.dL-1, HDL-c= 24 mg.dL-1) and olive oil-control (TC= 111 mg.dL-1, TG= 39 mg.dL-1, HDL-c= 36 mg.dL-1). The baru almond reduced total cholesterol (TC= 126 mg.dL-1) and triglycerides (61 mg.dL-1), and increased the level of HDL-C (36 mg.dL-1), compared to lard-control. The brazil nut reduced the levels of total cholesterol (119 mg.dL-1) and triglycerides (57 mg.dL-1) in relation to the control lard, but did not increased the level of HDL-c (23 mg.dL-1). The peanut, baru almond and brazil nut reduced lipid peroxidation (total MDA: baru almond= 92 mmol.g protein-1; peanut= 89 mmol.g protein-1; brazil nut= 154 mmol.g protein-1) compared to the lard-control (Total MDA= 346 mmol.g protein-1). Peanut consumption improved GSH (4.3 &#956;mol.g protein-1) and vitamin E (15.2 &#956;mol.g tissue-1) levels, as compared to the baru almond (GSH = 1.8 &#956;mol.g-1 protein; vitamin E = 10.8 &#956;mol.g tissue-1) and the brazil nut (GSH = 1.6 &#956;mol.g-1 protein; vitamin E = 11.6 &#956;mol.g tissue-1). It is recommended the association of these foods in a healthy diet, or as a coadjuvant to reduce the risk of dyslipidemia in populations that consume high-fat diets, replacing, preferably, foods with high content of saturated fat. / O presente estudo teve o objetivo de avaliar o efeito da ingestão de amêndoa de baru, amendoim e castanha-do-pará no perfil sérico e na peroxidação de lipídios em ratos tratados com dieta hiperlipídica. O efeito da ingestão desses alimentos no perfil sérico e na peroxidação de lipídios foi avaliado por meio de ensaio biológico com ratos Wistar, machos, adultos jovens, durante dois meses. As dietas foram formuladas segundo o American Institute of Nutrition (AIN-93G), sendo cinco dietas hiperlipídicas (0,1% de ácido cólico + 1% de colesterol + 5% de banha + 15% de uma das fontes lipídicas banha e azeite [controles], amêndoa de baru, amendoim ou castanha-do-pará) e uma dieta padrão (7% de óleo de soja). Ao final do experimento, foram coletados o sangue, para determinação do perfil lipídico sérico, e o fígado, para avaliar os níveis de malondialdeído total (MDA total), glutationa reduzida (GSH) e vitamina E hepáticas. O amendoim modulou o perfil lipídico sérico de ratos com dieta hiperlipídica, reduzindo os níveis de colesterol total (CT= 84 mg.dL-1) e triglicérides (TG= 46 mg.dL-1), e aumentando os níveis de HDL-colesterol (HDL-c=44 mg.dL-1), em relação ao controle-banha (CT= 217 mg.dL-1; TG= 223 mg.dL-1; HDL-c= 24 mg.dL-1) e ao controle-azeite (CT= 111 mg.dL-1; TG= 39 mg.dL-1; HDL-c= 36 mg.dL-1). A amêndoa de baru reduziu o colesterol total (126 mg.dL-1) e triglicérides (61 mg.dL-1), e aumentou os níveis de HDL-c (36 mg.dL-1), em comparação ao controle-banha. A castanhado- pará reduziu os níveis de colesterol total (119 mg.dL-1) e triglicérides (57 mg.dL-1) em relação ao controle banha, mas não aumentou os níveis de HDL-c (23 mg.dL-1). O amendoim, a amêndoa de baru e a castanha-do-pará reduziram a peroxidação lipídica (MDA total: amendoim= 89 mmol.g proteina-1; amêndoa de baru= 92 mmol.g proteina-1; castanha-dopará= 154 mmol.g proteina-1), em relação ao controle-banha (346 mmol.g proteína-1), sendo este efeito mais acentuado para o amendoim, pois ainda manteve os níveis de GSH (4,3 &#956;mol.g proteína-1) e de vitamina E (15,2 &#956;mol.g tecido-1) hepáticos elevados, em comparação à amêndoa de baru (GSH= 1,8 &#956;mol.g proteína-1; vitamina E= 10,8 &#956;mol.g tecido-1) e à castanha-do-pará (GSH= 1,6 &#956;mol.g proteína-1; vitamina E= 11,6 &#956;mol.g tecido-1). Recomenda-se a associação desses alimentos em uma dieta saudável, ou ainda, como coadjuvantes na redução do risco de dislipidemias em grupos populacionais que consomem dietas hiperlipídicas, como substitutos, preferencialmente, de alimentos ricos em gordura saturada.

Posouzení vlastností řezné hrany ocelového plechu při tavném a oxidační řezání pevnolátkovým laserem / Evaluation the properties of the cutting edge in fusion and flame cutting by solid state lasers

Dočekal, Miroslav January 2015 (has links)
The thesis compares oxidation and fusion laser cutting methods in the production of sheet components called Trager consoles. Individual methods of laser cutting are compared in terms of achieved quality and properties of cutting areas. Consequently, the effect of these properties on consecutive technological operations, which are mainly threading and pressing the nuts into components, are evaluated. In the experimental part of the thesis the roughness of cut surfaces was measured and the cuts were classified into quality classes according to the ČSN EN ISO 9013 standard. Metallographic samples were taken in order to measure hardness and determine its course in the direction from the cutting edge into the material. The metallographic samples were further used for capturing detailed images on the microscope and assessing the quality of nuts pressing. Afterwards, the cut moments affecting taps were measured in order to verify the impact of cutting edge properties on threading. These measurements provided sufficient data for comparing the influence of cutting edge properties in individual methods of laser cutting on consecutive operations. Finally, individual methods were compared in terms of production costs. According to all the data and the conclusions reached, fusion method was identified as the most suitable method of laser cutting for components manufacturing.
