Sensory properties of spices and the possibility of use in bakery products
No full textV živilski industriji se začimbe uporablja kot dodatek različnim živilom za izboljšanje senzoričnih lastnosti (barve, vonja, okusa in arome) ter kot antioksidante in protimikrobna sredstva. Kot začimbe uporabljamo različne dele rastlin, liste, semena, lubje, plodove in korenine. Pri ocenjevanju senzoričnih lastnosti različnih začimb si lahko pomagamo z McCormickovim senzoričnim kolesom začimb, ki vključuje senzorične opisnike za vonj in aromo. Proučili smo možnosti uporabe začimb v pekovskih izdelkih kot dodatkov za izboljšanje barve in arome ter kot antioksidativnih in protimikrobnih učinkovin. V okviru eksperimentalnega dela diplomskega dela smo želeli raziskati vpliv dodatka izbranih začimb (janeža, pimenta, ingverja in kurkume) na všečnost nekaterih senzoričnih lastnosti (videz, vonj, okus, aroma, krhkost, topnost) in celokupno všečnost piškotov. Spekli smo piškote z dodatkom začimb in jih senzorično ocenili s panelom študentov. Večje razlike med vzorci so bile pri videzu, vonju, okusu in aromi. Kontrolni vzorec brez začimb je prejel najvišje ocene pri večini senzoričnih lastnosti, razen videzu, kjer so bili bolje ocenjeni le piškoti z ingverjem. Pri ocenjevanju topnosti in krhkosti piškotov so bili rezultati med vzorci primerljivi. Pri ocenjevanju celokupne všečnosti so študenti najboljše ocenili kontrolne piškote brez dodatkov, sledili so piškoti z janežem, nato piškoti z dodatkom pimenta, najslabše so bili ocenjeni piškoti z ingverjem in s kurkumo. Pri dodatku ingverja je študente najbolj zmotil pekoč pookus piškotov, pri dodatku kurkume pa preveč intenzivna rumena barva.In food industry, spices are mostly used to improve colour, odour, taste and aroma of different foods, and as antioxidants and antimicrobial agents. Spices come from different parts of plants, such as leaves, seeds, bark, fruits, roots, berries and pods. Sensory properties of different spices can be described with McCormick\u27s spice wheel, which includes sensory descriptors for odour and aroma. In graduation thesis we have studied the use of spices in bakery products for improvement of colour and aroma, and antioxidant and antimicrobial activity. Also we wanted to investigate the effect of the addition of selected spices (anise, allspice, ginger and turmeric) on some sensory properties (appearance, odour, taste, aroma, fragility and solubility) and overall liking of cookies. The cookies were prepared with addition of spices and then sensory evaluated with a panel of students. The major differences between the cookies were in appearance, odour, taste and aroma. The control sample (without spices) received the highest scores for most sensory properties except for the appearance, where only cookies with ginger were evaluated better. In assessing the solubility and fragility of cookies the hedonic scores were comparable between the samples. In evaluating the overall likeness, the best results were obtained for the control, followed by cookies with anise and allspice, while the lowest scores were obtained for cookies with ginger and turmeric. Cookies with ginger received lower hedonic score because of spicy, burning aftertaste, whereas cookies with turmeric were evaluated lower because of too intense yellow colour
Sensory acceptance of reformulated ice cream
No full textNamen raziskave je bil določiti razlike v fizikalno-kemijskih in senzoričnih lastnostih standardnega vzorca v primerjavi z reformuliranim vzorcem sladoleda na palčki. Analizirali smo štiri pare vzorcev, ki smo jim določili hranilne vrednosti s fizikalno-kemijskimi analizami in iz podatkov izračunali vrednost Nutri-Score. S senzorično analizo smo s preskusom primerjave v parih preverjali, če obstajajo razlike v sladkosti med vzorcema v paru. Z opisno metodo »Označi vse kar ustreza« (CATA) smo določili opisnike, ki jih mladi potrošniki povezujejo z vzorci. Na koncu smo z ocenjevanjem na 9-točkovni lestvici določili stopnjo ugajanja posameznih senzoričnih lastnosti in celokupno všečnost vsakega vzorca. Pripravili smo tudi anketni vprašalnik o potrošniških navadah, povezanih z uživanjem sladoleda. Reformulirani vzorci so imeli manjšo vsebnost ogljikovih hidratov, sladkorjev in posledično nižjo energijsko vrednost. Vsebovali so več prehranskih vlaknin in beljakovin. Vsebnost maščob se je statistično razlikovala le pri dveh parih, kjer je imel reformuliran vzorec nižjo vrednost. Prav tako so reformulirani vzorci prejeli Nutri-Score oceno C, medtem ko so standardni vzorci prejeli za en razred slabšo oceno D. Pri treh parih smo dokazali razliko v intenzivnosti sladkega okusa. V ocenjevanju z metodo CATA se je večina opisnikov v paru skladala in prav tako pri hedonskem ocenjevanju znotraj parov ni bilo značilnih razlik med povprečnimi hedonskimi ocenami. Rezultati anketnega vprašalnika so pokazali, da študentje uživajo sladoled najpogosteje poleti, nekajkrat na teden s prijatelji ali kot posladek. Večina ni pozornih na hranilno vrednost sladoleda, najljubši so jim tradicionalni okusi in raje imajo mlečni sladoled v kornetu, ki ga pogosteje kupijo v trgovinah.The aim of this research was to determine the differences in the physical-chemical and sensory properties of the standard sample compared to the reformulated samples of ice cream on a stick. We analyzed four pairs of samples, for which we determined the nutritional values by physical-chemical analysis and calculated the Nutri-Score value from the data. Sensory analysis was used to determine differences in sweetness within pairs using a paired comparison discrimination test. Using the descriptive \u27Check all that apply\u27 (CATA) method, we determined the descriptors that young consumers associate with the samples. With a 9-point scale, we rated their attribute liking of and the overall liking. We also prepared a questionnaire on consumer habits related to the consumption of ice cream. The reformulated samples had a low content of carbohydrates, sugars and consequently a lower energy value. They had a higher value of dietary fiber and protein. The fat content was statistically different only in two pairs, where the reformulated sample had a lower value. The reformulated samples received a Nutri-Score score of C, while the standard samples received one grade worse score of D. In three pairs, we determined a difference in the intensity of sweetness. In the evaluation with CATA, most of the descriptors in the pair were similar, and in the hedonic evaluation, there were no significant differences in liking within the pairs. In the questionnaire, we determined that students consume ice cream most often in the summer, several times a week with friends or as a dessert. Most of them do not pay attention to the nutritional value of ice cream, they prefer traditional flavors, milk ice cream in a cone, which is more often bought in stores
Differential stability of 2'F-ANA*RNA and ANA*RNA hybrid duplexes: roles of structure, pseudohydrogen bonding, hydration, ion uptake and flexibility
No full text14 pags., 7 figs., 3 tabs.Hybrids of RNA with arabinonucleic acids 2′F-ANA and ANA have very similar structures but strikingly different thermal stabilities. We now present a thorough study combining NMR and other biophysical methods together with state-of-the-art theoretical calculations on a fully modified 10-mer hybrid duplex. Comparison between the solution structure of 2′F-ANA•RNA and ANA•RNA hybrids indicates that the increased binding affinity of 2′F-ANA is related to several subtle differences, most importantly a favorable pseudohydrogen bond (2′F-purine H8) which contrasts with unfavorable 2′-OH-nucleobase steric interactions in the case of ANA. While both 2′F-ANA and ANA strands maintained conformations in the southern/eastern sugar pucker range, the 2′F-ANA strand's structure was more compatible with the A-like structure of a hybrid duplex. No dramatic differences are found in terms of relative hydration for the two hybrids, but the ANA•RNA duplex showed lower uptake of counterions than its 2′F-ANA•RNA counterpart. Finally, while the two hybrid duplexes are of similar rigidities, 2′F-ANA single strands may be more suitably preorganized for duplex formation. Thus the dramatically increased stability of 2′F-ANA•RNA and ANA•RNA duplexes is caused by differencesin at least four areas, of which structure and pseudohydrogen bonding are the most important. © The Author(s) 2010.

Dinî Bir Sembol Olarak Bamyan Buda heykelleri: Dünü ve Bugünü
No full textBudizm, MÖ. 6. asırlarda Hindistan’da ortaya çıkmıştır. Bu dinî ve ahlakî öğretiyi benimseyip çevresine öğretmeye çalışan Gautama Sakiamuni’nin ölümünden sonra kendisine “aydınlanan” anlamında Buddha denilmeye başlanmıştır. Buddha’nın izlediği yol ve öğretilerinin din olarak Hindistan’ın muhtelif bölgelerine ve Hint hudutlarının dışına çıkması ise Maurya İmparatoru Aşoka döneminde olmuştur. Çalışmamızın ana konusunu oluşturan Buda Heykellerinin yapımı ise MS. Kuşan İmparatorluğu döneminde tıraş edilmiştir. Biri 53 bir diğeri ise 35 metre yükseklikte olan Buda Heykelleri, bugün Afganistan sınırlarında kalan Bamyan şehrinde yapılmıştır. Afganistan’da Budizm’in yayılması, Bamyan şehrinin Budizm’in merkezlerinden biri olarak kabul görmesi, dinî bir sembol ve kültürel miras olarak kabul edilen heykellerin yapılışı ve tahrip edilişi, çalışmamızın tali konuları arasında değerlendirilmiştir. Buna bağlı olarak çalışmamızda, Afganistan’ın Bamyan şehrinde bulunan iki adet Buda Heykeli’nin, Budizm’in en önemli objektif unsuru ve dinî sembolü olarak tıraş edilmesi, dinî bir unsur olarak kullanılması, kültürel ve tarihi miras olarak muhafaza edilmesi ile tahrip girişimleri ve tahrip edilmesi sürecinin araştırılması amaçlanmıştır. Çalışmamızda cevap aranan sorular ise dinî bir sembol olarak Afganistan’ın Bamyan şehri Hindukuş dağının eteğinde dağdan oyularak yapılan iki adet Buda Heykeli’nin ne zaman, kimler tarafından yapılmış? Dinî, tarihi ve kültürel değeri nedir? Bu önemli dinî sembol, günümüzde ne durumdadır, neden tahrip edilmiştir ve ne kadarı tahrip edilmiştir? Çalışma, Budizm’in Afganistan’ın Bamyan şehrindeki geçmişi, dinî bir sembol olarak Bamyan’daki Buda Heykellerinin yapılışı, muhafaza edilmesi, tahrip girişimleri ve 2001’deki tahrip edilmesi serüveni ile sınırlandırılmıştır. Yöntem olarak nitel araştırma desenlerinden literatüre dayalı tarama yöntemi tercih edilmiştir. Toplanan ikincil verilerin betimsel analiz teknikle değerlendirilip yorumlanmıştır

The Literary Legacy of Ana Plácido: Autobiographical Matrix and Meaning-Seeking
No full textDissertação de Mestrado em Literatura de Língua Portuguesa apresentada à Faculdade de LetrasThe present survey is an analysis of the literary legacy of Ana Plácido – Luz coada por ferros and Herança de lágrimas – exploring the genealogical similarities between these and two other works of European literature: Burned Alive and A Psychologist Experiences the Concentration Camp by Souad and Viktor Frankl respectively. It is proposed that the meaning-seeking conception developed by the psychiatrist Viktor Frankl can be a useful conceptual tool to understand the autobiographical creative process informing several existential and literary aspects of Ana Plácido’s work.Our observation of several affinities led to the creation of an autobiographical creative model related to Viktor Frankl’s meaning-seeking concept developed in the context of logotherapy. The application of this model to the work of Ana Plácido proved to be crucial to the analysis of its existential and literary aspects. In fact, we have found significant confluences between the 19th century Portuguese author and the already-mentioned work by Souad (21st century) and Frankl (20th century), pointing indisputably to the use of writing and its diffusion as a form of overcoming limit situations, which is also a form of social activism. In addition to applying the creative model in question, a literary meditation was carried out adapted to the peculiarities of Plácido’s work which is absent – or almost so – from the canons of the published and studied Portuguese authors. We started from the already mentioned genealogical concept applied to Ana Plácido´s historical and sociocultural context, whilst looking at the network of literary associations with previous authors such as Madame de Staël, George Sand, Marquise of Alorna, and Catarina de Balsemão, and current ones such as Camilo Castelo Branco. From these, we sought tools that allowed us to unlock autobiographical codes which are invaluable in this type of textual analysis. As for the literary analysis of the works, we tried to be as comprehensive as possible. This survey is generally informed by semiotic, structuralist, and stylistic approaches, including rhetoric, along with reception theory. We tried in this way to highlight not only the documentary value of her work (particularly regarding the female condition in the 19th century), and to emphasise the singularity of her writing in its individual, social, and literary aspects.A presente investigação pretende fazer uma incursão pelo legado literário de Ana Plácido – Luz coada por ferros e Herança de lágrimas – a partir das semelhanças genológicas entre estas e outras duas obras da literatura europeia: Queimada viva e Um psicólogo no campo de concentração, de Souad e Viktor Frankl respetivamente. As afinidades que observámos levaram-nos à elaboração de um modelo operatório de cariz autobiográfico relacionado com o conceito de construção de sentido, desenvolvido no âmbito da logoterapia, pelo psiquiatra Viktor Frankl. A sua aplicação na obra de Ana Plácido revelou-se fulcral nos vários aspetos vivenciais e literários analisados. De facto, há confluências significativas entre a autora portuguesa do século XIX e as obras mencionadas de Souad (século XXI) e Frankl (século XX), que apontam iniludivelmente para um uso da escrita e da sua difusão como forma de ultrapassagem de uma situação limite, que é também uma forma de intervenção social.A par da testagem do modelo operatório em causa, é efetuada uma mediação literária adaptada às peculiaridades da obra de Ana Plácido, ausente, ou quase, do cânone dos escritores portugueses divulgados e estudados. Partimos do conceito genológico atrás identificado, inserindo no contexto histórico e sociocultural de Ana Plácido, analisando também a rede de relações literárias com personagens do passado, Madame de Staël, George Sand, marquesa de Alorna e Catarina de Balsemão, e do presente, em particular Camilo Castelo Branco. Desse conjunto procurámos instrumentos para aceder aos códigos autobiográficos, imprescindíveis para uma análise textual desta natureza. Quanto à análise literária das obras, procurámos que fosse o mais possível abrangente. Em linhas gerais, apoia-se nos estudos semióticos, estruturalistas e estilísticos, incluindo os retóricos, e abarca igualmente a teoria da receção. Procuramos assim pôr em evidência, não só, o interesse documental da sua obra (particularmente no que toca à condição feminina no século XIX), destacando a singularidade da escrita placiana em termos individuais, sociais e literários

As mulheres do império: uma leitura de Ana de Amsterdam / Women’s Empire: A Reading of Ana de Amsterdam
No full textResumo: Enquadrado no bojo da produção identificada como “literatura dos retornados”, o interesse principal de Ana de Amsterdam (2016a), de Ana Cássia Rebelo, não recai nas imagens traumáticas do retorno ou na violência praticada entre colonizadores e colonizados, como é recorrente no gênero. De forma até sintomática, as lembranças de África são esporádicas na menina de cinco anos que deixou Moçambique junto à família. Em seu lugar, a exuberância de uma Índia portuguesa sonhada e projetada por ela ocupam as lacunas de um presente insatisfatório, dividido entre a criação dos três filhos de um casamento em crise e o emprego burocrático desempenhado numa Lisboa pouco atrativa. Em ambos, tanto na Goa portuguesa como no trajeto para o trabalho, despontam narrativas de mulheres que constituem a síntese entre o diário íntimo de Ana e a escrita testemunhal da diáspora. Numa primeira parte do estudo, recupera-se a gênese do romance no formato do blog assinado pela autora, evidenciando a “escrita do eu”, nos moldes dos estudos de autobiografias, diários e afins. O segundo momento volta-se para a escrita testemunhal no lastro da narrativa pós-colonial e também da pós-memória. Em comum, os dois planos tratam da perspectiva feminina, seja na batalha contemporânea da cosmopolita Lisboa, seja nos desdobramentos silenciados do pós-colonialismo, em meio às histórias duplicadas de outras tantas Anas.Palavras-chave: Ana de Amsterdam; Ana Cássia Rebelo; diário íntimo; literatura de testemunho; blogs.Abstract: Framed in the center of the production identified as “literature of the returnees”, the main focus of Ana de Amsterdam (2016a) by Ana Cássia Rebelo, does not lie in the traumatic images of the return or in the violence practiced between colonizers and colonized, as it is usually the case in this genre. Somehow, even symptomatically, African memories are sporadic in the five-year-old girl who left Mozambique with her family. Instead, the exuberance of a Portuguese India, dreamed and projected by her, occupies the gaps of an unsatisfactory present, dividing herself to raise three children of a marriage in crisis and work in the bureaucratic employment situated in an unattractive Lisbon. In both, Portuguese Goa and on the way to work, narratives of women emerge and represent the synthesis between Ana’s private diary and the testimonial writing of the diaspora. In a first part of the study, the genesis of the novel is recovered in the form of a blog signed by the author, emphasizing the “writing of the self”, in the molds of autobiographies, journals and etc. The second moment turns to the testimonial writing in the basis of the postcolonial narrative and also of the post-memory. In common, the two plans deal with the feminine perspective, whether in the contemporary battle of cosmopolitan Lisbon or in the silenced developments of postcolonialism, in the middle of the duplicate stories of so many Anas.Keywords: Ana de Amsterdam; Ana Cássia Rebelo; diary; testimonial literature; blogs
