Dados experimentais de atividade de água dos sistemas binários água-açúcares foram coletados da literatura e os parâmetros de interação binária água-açúcar foram obtidos pelo ajuste ao modelo. Foi avaliada a capacidade do modelo predizer o equilíbrio multicomponente (comparando com valores experimentais disponíveis na literatura), utilizando-se dos parâmetros de interação binária açúcar-água ajustados e adotando como nulos os parâmetros de interação binária açúcar-açúcar. Teve também como objetivo, avaliar as características do equilíbrio quando se aplica pressão elevada. Os parâmetros de interação binária foram obtidos pelo ajuste do modelo termodinâmico a dados experimentais do equilíbrio líquido-vapor (dados de atividade de água em sistemas binários). As fugacidades, ou pressão de sublimação, dos açúcares no estado sólido foram obtidas a partir de dados de solubilidade, calculando a fugacidade do açúcar na solução aquosa saturada. Os resultados obtidos indicam que a modelagem termodinâmica à pressão atmosférica correlaciona bem os dados experimentais dos sistemas binários, apresentando um desvio médio de 5% na fração mássica do açúcar ou o equivalente a O) 7% de desvio médio em atividade de água. Um desvio um pouco maior, de 7% em média, foi observado para o equilíbrio líquido-vapor multicomponente. Valores de fugacidade do açúcar no estado sólido foram estimados e quando comparados a valores de pressão de sublimação, extrapolando os dados experimentais, para glicose e para a xilose, mostraram que os valores são coerentes em ordem de grandeza com os experimentais, principalmente para a xilose, no entanto a modelagem não reproduziu bem os dados experimentais do equilíbrio sólido-líquido. A pressões elevadas, os cálculos usando a modelagem termodinâmica com parâmetros obtidos a baixa pressão indicam que a solubilidade da sacarose decresce com o aumento de pressão e a solubilidade da glicose tem um leve acréscimo com o aumento da pressão, sugerindo com isto que o uso de pressões elevadas pode vir a ser uma técnica para processos de separações / Abstract: The thermodynamic model that use the Equation of State of Peng-Robinson was used in the phase equilibrium of sugars aqueous at atmospheric pressure (where there are experimental data of equilibrium), for to afterwards to employ it at high pressures systems. Water activity experimental data of the binary systems water-sugars were collected of the literature and the binary interaction parameters of water-sugar were obtained fitting the model to these experimental binary equilibrium data. It was evaluated the capacity of the model to predict the equilibrium of the multicomponent system (comparing with available experimental values in the literature), using the binary interaction parameters fittings to the sugar-water system and considering null the binary interaction parameters of the sugarsugar system. It were evaluated also the characteristics of equilibrium of these binary systems at high pressure when it applies elevated pressure. The binary interaction parameters were obtained by the fitting of the thermodynamic model to the experimental data of the vapour - liquid equilibrium (data of water activity in binary systems). The fugacity, or sublimation pressure, of the sugars in the solid state were obtained by the solubility data, calculating the fugacity of the sugar in the saturated aqueous solution. The results indicate that the thermodynamic modeling, shawed a good correlation to the experimental data of the binary systems (at atmospheric pressure), showing an average deviation of 5% in the sugar mass fraction, equivalent to 0,17% of average deviation in water activity. For the multicomponent vapour-liquid equilibrium was observed a deviation of 7% on average. Values of sugar fugacity in the solid state were estimate and when compared to the sublimation pressure values, extrapolated from the experimental data, for glucose and xylose, showed that the values are coherent, and in the same order with the experimental data, most1y for xylose. However the modeling did not showed a good reproduction the solid-liquid equilibrium of the experimental data. The calculations using the thermodynamic modeling with at high pressure the parameters obtained at low pressure, indicate that the solubility of the saccharose decreases with the pressure and the solubility of the glucose increase with the pressure, showing that the use of the elevated pressures can become a technique for separations processes / Mestrado / Mestre em Engenharia de Alimentos

As indústrias têm deixado de produzir o suco de laranja integral pasteurizado em substituição ao suco de laranja reconstituído devido, principalmente, à dificuldade em se produzir esse tipo de suco durante todo o ano com as mesmas características. Esse trabalho objetivou avaliar sensorialmente esses dois tipos de sucos. Sete provadores selecionados e treinados avaliaram a aparência, aroma, sabor e textura de amostras de suco de laranja utilizando a Análise Descritiva Quantitativa (ADQ). O teste de aceitação pelo consumidor foi realizado com cento e um provadores não treinados, utilizando a escala hedônica e um mapa de preferência foi traçado. A ADQ mostrou que houve diferenças significativas (p<0,05) em relação a: cor amarela, concentrado, aroma laranja, aroma de sumo, sabor de laranja, sabor passado, sabor cozido. Entretanto, não houve diferenças significativas (p>0,05) entre as amostras do suco em relação a: aroma cítrico, aroma cozido, aroma doce, sabor sumo, gosto doce, gosto ácido e encorpado. O suco reconstituído apresentou os atributos com maior intensidade para cor amarela, concentrado, aroma de sumo, sabor passado e sabor cozido em relação ao pasteurizado enquanto esse, o aroma e sabor de laranja foram os atributos mais acentuados. O teste de consumidor indicou que os dois sucos tiveram aceitação parecidas situando-se entre os termos hedônicos indiferente e gostei ligeiramente e o resultado do mapa de preferência mostrou baixa aceitação pela grande maioria dos consumidores de suco. Os dados de HPLC não mostraram diferença entre as amostras de suco analisadas. / The industries are allowing to produce the orange juice pasteurized in substitution to the orange juice reconstituted, mainly, the difficulty in producing this type of juice during the year with the same characteristics. This work objectified to evaluate these sensorially two types of juices. Seven selected and trained panelists evaluated the appearance, aroma, flavor and texture of orange juice pasteurized and orange juice reconstituted by Descriptive Quantitative Analysis (QDA). The consumer test and a preference map was done with one-hundred one non-trained panelists through the hedonic test. The QDA showed significant differences (p<0,05) concerning yellow color, concentrate, orange odor, the highest point odor, orange flavor, passed flavor and cooked flavor. However, there was no significant difference (p>0,05) concerning: citric aroma, candy aroma, cooked aroma, supreme flavor, candy taste, acid taste and viscosity. The reconstituted juice presented the attributes with bigger intensity for yellow color, concentrate, the highest point aroma, last flavor and flavor cooked in relation to the pasteurized and this juice, the aroma and flavor of orange had been the more accented attributes. The consumer test indicated that orange juice pasteurized and orange juice reconstituted were acceptance similar placing itself enters the hedonic terms indifferent and liked slightly and the result of the preference map showed low acceptance by majority of the juice consumers. The HPLC data hadn’t shown the difference enter the analyzed juice samples.

This diploma thesis is focused on determination the aroma profile of selected species of fruit juices (apple, grape, carrot, orange, blackcurrant and elderberry juice). The theoretical part deals with the composition and properties of selected species of fruits and their juices, then deals with juice‘s technological process and selected methods for the determination of aroma active compounds. The experimental part describes the instrumental and sensory analysis. The six pure fruit juices and five mixed fruit juices were used for instrumental evaluation. The aroma active compounds were extracted by SPME and subsequently identified and quantified by gas chromatography. The sensory evaluation was performed by ranking test and evaluation using hedonic scale.

The antibacterial efficacy of hydrogen peroxide treatments in four fruit juices was determined. Preservative free apple cider, white grape, and purple grape juice were inoculated with ~ 6.4 log CFU/ml of a five strain, acid adapted, nalidixic acid resistant E. coli O157:H7 cocktail. Orange juice was inoculated with a comparable Salmonella spp. cocktail. In the first study, 0.017% and 0.012% H₂O₂ was added in combination with 0.1% and 0.3% of the dominant organic acid (OA) to 4°C and 25°C juices, with samples taken each day for 21 days. H₂O₂ was a significant factor in all juices (p < 0.05) except white grape (lack of data), and both 0.017% H₂O₂ treatments reduced counts in apple cider, orange juice, and white grape to undetectable numbers within 48 hrs as cultured on tryptone soy agar + 0.05% nalidixic acid (TSAN). Treatments in purple grape juice were less effective overall, and more dependent on OA concentration (p < 0.001) than H₂O₂. There were instances where bacterial survival in apple cider, purple grape, and orange juice continued for 21 days after treatment, and sometimes outlasted the control. These occurrences were dependent on temperature (25°C) and H₂O₂ (0.012%), but not on OA. However, OA concentration was a significant factor (p < 0.05) overall in apple cider and purple grape juice, but not in orange juice. In the second study, 0.015% and 0.03% H₂O₂ was added to 10, 25, and 40°C apple cider and orange juice inoculated with 6.4 log CFU/ml E. coli O157:H7 and Salmonella spp. respectively. Only 0.03% H₂O₂ was effective in reducing counts to undetectable numbers in both juices. However, both temperature and H₂O₂ were significant factors (p < 0.0001) in bacterial destruction, with 0.03% H₂O₂ at 40°C giving undetectable numbers at ≤ 3 and ≤ 6 hours in orange juice and apple cider respectively. It has been demonstrated that at ~ ≥ 0.017%, H₂O₂ can provide a 5 log reduction of these pathogens in fruit juice. Increasing temperature and organic acid concentration can improve its rate of effectiveness in certain juices. However, sensory concerns may negate its use in some products. / Master of Science

Thesis (MSc Food Sc)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: Nectar formulations containing red-fleshed plum pulp and varying amounts of red-fleshed plum skin extract were developed. Red-fleshed plum nectar formulations containing 0, 8, 16, 24, and 32% skin extract were benchmarked against twenty-two commercial beverages containing red, violet and blue fruits. The total soluble solid content, pH, titratable acidity, colour, total polyphenolic, individual polyphenolic, total anthocyanin, and ascorbic acid contents, as well as antioxidant activity (oxygen radical antioxidant capacity (ORAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, and ferric reducing/antioxidant power (FRAP)) of the commercial beverages and plum formulations were determined. The plum nectar formulations had similar or higher total polyphenolic content, antioxidant activity, and colour values than the average for the commercial beverages. The individual polyphenolic compounds analysed in the nectar formulations were cyanidin-3-glucoside, cyanidin-3- rutinoside, quercetin-3-glucoside, quercetin-3-rutinoside, quercetin-3-xyloside, and neochlorogenic acid. Increasing polyphenolic content and antioxidant activity was observed with an increase in skin extract content of the formulations. The sensory attributes of the formulations were plum and plantlike aroma, plum and plantlike flavour, sweetness, acidity, and astringency. Increases in plantlike aroma and flavour, acidity, and astringency in conjunction with decreases in plum aroma, plum flavour, and sweetness extract were observed with an increase in skin extract. Consumer analysis indicated that all formulations were acceptable. The 0 and 16% skin extract formulations were most preferred, while the 32% skin extract formulation was least preferred. A shelf-life study was conducted in two phases. In Phase 1, the 0, 16 and 24% skin extract formulations were stored at 0 and 5°C (analysis time points: before pasteurisation, after pasteurisation (week 0), and after 1, 2, 4, 6, 8, 12, 16, 18, 20, and 24 weeks of storage). Chemical analyses conducted included colour, total polyphenolic, individual polyphenolic compound, and total anthocyanin contents, and antioxidant activity (DPPH• scavenging activity). Results from Phase 1 indicated close associations between the 16 and 24% skin extract formulations, and between these formulations and all chemical attributes. Regression analysis of results indicated significant (P 0.05) decreases in red colour, total anthocyanins, cyanidin-3-glucoside, cyanidin-3- rutinoside, DPPH• scavenging activity, total polyphenolic content, quercetin-3-rutinoside, and quercetin- 3-xyloside for formulations stored at 0°C. The total and red colour, total anthocyanins, cyanidin-3- glucoside, and cyanidin-3-rutinoside in formulations stored at 5°C showed similar results. During Phase 2 of the shelf life study, sensory analysis was conducted on the 0 and 24% skin extract formulations stored at 5°C (preparation time points: 0, 1, 2, and 3 months). Sensory attributes, including plum, plantlike, and raisin flavour, sweetness, acidity, and astringency, were stable during storage. Chemical results from Phase 2 were similar to those of Phase 1. The chemical and sensory stability of formulations after 24 weeks of storage in Phase 1 and Phase 2 indicated that, with the exception of the anthocyanin degradation, the formulations could be beneficial to juice industries. Thus, red-fleshed plum nectars have the potential to compete with high-antioxidant fruit beverages. / AFRIKAANSE OPSOMMING: Nektarformulasies wat rooivleis pruimpulp en varieërende hoeveelhede rooivleis pruimskilekstrak bevat, is ontwikkel en ondersoek. Rooivleis pruimnektarformulasies wat 0, 8, 16, 24, en 32% skilekstrak bevat, is vergelyk met twee-en-twintig kommersiële drankies wat rooi, violet en blou vrugte bevat. Die totale oplosbare vastestof, totale polifenoliese, individuele polifenoliese, totale antosianien- en askorbiensuur inhoude, sowel as die pH, titreerbare suurheid, kleur, antioksidant aktiwiteit (suurstofradikale antioksidantkapasiteit (ORAC), 2,2-difeniel-1-pikrielhidrasiel (DPPH) radikaal blussingsaktiwiteit, en ysterreduserende/antikoksidantkrag (FRAP)) van die kommersiële drankies en pruimnektarformulasies, is bepaal. Die pruimnektarformulasies het soortgelyke of hoër totale polifenoliese inhoud, antioksidantaktiwiteit, en kleurwaardes gehad in vergelyking met die gemiddelde vir die kommersiële drankies. Die individuele polifenoliese verbindings wat in die nektarformulasies geanaliseer is, was sianidien-3-glukosied, sianidien-3-rutinosied, kwersetien-3-glukosied, kwersetien-3-rutinosied, kwersetien-3-xylosied, en neochlorogeniese suur. ‘n Toenames in die kleurwaardes, polifenoliese inhoud, en antioksidantaktiwiteit is waargeneem met ‘n toename in skilekstrak is in die formulasies. Die sensoriese eienskappe van die formulasies was pruim- en plantagtige aroma, pruim- en plantagtige geur, soetheid, suurheid, en frankheid. Toenames in plantagtige aroma en geur, suurheid en frankheid, sowel as ‘n afname in pruimaroma, pruimgeur, en -soetheid, is met ‘n toename in skilekstrak waargeneem. Verbruikersanalise het aangedui dat al die formulasies aanvaarbaar was. Die 0 en 16% skilekstrakformulasies was die mees aanvaarbaarste, terwyl die 32% skilekstrakformulasie die minste aanvaarbaar geag is. ‘n Rakleeftydstudie is in twee fases gedoen. In Fase 1 is die 0, 16, en 24% skilekstrakformulasies by 0 en 5°C gestoor (analiseringstydpunte: voor pasturisasie, na pasturisasie (week 0), en na 1, 2, 4, 6, 8, 12, 16, 18, 20, en 24 weke van berging). Chemiese analise wat gedoen is, sluit totale polifenoliese, individuele polifenoliese verbinding, en totale antosianien inhoude, sowel as kleur en antioksidantaktiwiteit (DPPH• blussingsaktiwiteit) in. Resultate van Fase 1 het ‘n nou verband tussen die 16 en 24% skilekstrakformulasies, sowel as tussen hierdie formulasies en hul chemiese kenmerke aangedui. Regressie-analise van resultate het betekenisvolle (P 0.05) afnames geïllustreer in rooi kleurwaardes, DPPH• blussingsaktiwiteit, sowel as totale antosianiene, sianidien-3-glukosied, sianidien-3-rutinosied, totale polifenoliese, kwersetien-3-rutinosied, en kwersetien-3-xylosied inhoude van die formulasies wat by 0°C gestoor is. Die totale kleur-, rooi kleurwaardes, sowel as totale antosianien, sianidien-3-glukosied, en sianidien-3-rutinosied in die formulasies wat by 5°C gestoor is, het soortgelyke resultate gegee. Gedurend Fase 2 van die rakleeftydstudie is sensoriese analise op die 0 en 24% skilekstrakformulasies wat by 5°C gestoor is, gedoen (voorbereidingstydpunte: 0, 1, 2, en 3 maande). Sensoriese eienskappe, insluitend pruim-, plantagtige-, en rosyntjiesmake, soetheid, suurheid, en frankheid, was stabiel gedurende berging. Chemiese resultate van Fase 2 was soortgelyk aan dié van Fase 1. Die chemiese en sensoriese stabiliteit van die formulasies na 24 weke van opberging in Fase 1 en Fase 2 nieteenstaande antosianienafname, het aangedui dat die formulasies voordelig kan wees vir die vrugtedrankiebedryf. Dus het rooivleis pruimnektars die vermoeë om met hoë antioksidant vrugtedrankies mee te ding.

Embora no Brasil não existam estudos visando o processamento dos frutos, o umê é muito consumido e apreciado em países asiáticos devido às propriedades nutracêuticas relacionadas ao consumo de concentrados de frutos verdes ou flores, por isso, o objetivo do presente trabalho é possibilitar o aproveitamento desta matéria prima pela elaboração de um produto apreciado pelo consumidor brasileiro, com apelo saudável. Foram utilizados frutos de diferentes localidades do Estado de São Paulo, caracterizados segundo suas dimensões, massa e rendimento no despolpamento, bem como seus aspectos botânicos. Os frutos tiveram a sua maturação acompanhada pela cor e após maduros, foram branqueados termicamente, despolpados, desaerados e envasados a quente na planta piloto de Frutas e Hortaliças da Faculdade de Engenharia de Alimentos da UNICAMP. Foram realizadas análises de textura instrumental em frutos verdes e maduros. Na Universidade Estadual de Ponta Grossa (UEPG) foram realizadas análises químicas de compostos fenólicos e da atividade antioxidante dos frutos colhidos em cinco diferentes localidades do Estado de São Paulo e em diferentes graus de maturação, bem como as análises reológicas. As dimensões dos frutos (2,0 a 3,6 cm de diâmetro) e suas massas foram significativamente inferiores (6 a 16 gramas) aos valores relatados em trabalhos científicos de autores asiáticos. Os frutos não apresentaram variação significativa do teor de compostos fenólicos e da atividade antioxidante durante a maturação, a partir de sua completa maturação fisiológica (88 dias após a floração), cujos valores foram de 147 a 226 mg catequina/ g base seca e 21 a 34 µMol Trolox/ g base seca, respectivamente. A reologia foi realizada para polpa de umê nas concentrações de 6 a 9 ºBrix, nas temperaturas de 15 a 75 ºC. O comportamento reológico da polpa de umê se mostrou independente do tempo, com comportamento não-Newtoniano e pseudoplástico (Herschel-Bulkley). Apresentou bom ajuste aos modelos reológicos de Herschel-Bulkley, Casson, Bingham e Lei da Potência. A equação de Arrhenius possibilitou o cálculo da energia de ativação para diferentes concentrações de polpa. A consistência da polpa de umê é altamente influenciada pela concentração dos sólidos solúveis do produto. A micro estruturação da polpa com alginato, para adição ao suco clarificado de umê mostrou-se estável com a elevação do pH para valores superiores a 3,5 / Abstract: Prunus mume is a stone fruit that exhibits high robustness and agriculture adaptability. Its use is being extensively studied as rootstocks for peaches, nectarines and plums. Although in Brazil there are no studies for mume fruit processing, in Asian countries this fruit is widely consumed and appreciated due to the nutraceutical properties related to the consumption of concentrated or processed green-stage fruits or flowers. The present work aim is to produce a highly acceptable product with health appeal. Fruits from different locations in São Paulo State were characterized according to their size, weight and yield pulping, as well as its botanical characteristics. Fruits were evaluated during maturation by color and after fully-ripe they were thermally blanched, pulped, deaerated and hot filled in the pilot plant of Fruits and Vegetables of the Faculty of Food Engineering at UNICAMP. Instrumental texture analyses of green and ripe fruits were performed. At the State University of Ponta Grossa (UEPG) were done chemical analysis of total phenolic compounds and antioxidant activity of fruits collected in 5 different locations in the State of São Paulo and at different stages of maturity, as well as rheological analyses. The fruit dimensions (2.0-3.6 cm diameter) and their mass were significantly lower (6-16 g) than values reported in scientific studies done in Asian countries. Total phenolic content and antioxidant activity did not vary during maturation of the fruit, from its full physiological maturity (88 days after flowering), with values of 148-226 mg catechin/ g dy basis and 21- 34 mMol Trolox/ g dry basis, respectively. Pulp concentrations at 6-9 °Brix were used to study the rheological properties from 15 to 75 °C. The rheological behavior of mume pulp is non-Newtonian pseudoplastic (Herschel-Bulkley). Herschel-Bulkley, Casson, Bingham and Power Law rheological models described well the mume pulp behavior. The Arrhenius equation was used to calculate the activation energy for different concentrations of pulp and was shown that consistency is highly influenced by soluble solids concentration. Micro structured particles of pulp with alginate for adding into clarified mume juice just showed stability with pH increase over 3.5 / Doutorado / Tecnologia de Alimentos / Doutor em Tecnologia de Alimentos
