Home Cooking and Phenolics: Effect of Thermal Treatment and Addition of Extra Virgin Olive Oil on the Phenolic Profile of Tomato Sauces

Tomato products are a key component of the Mediterranean diet, which is strongly related to a reduced risk of cardiovascular events. The effect of cooking time (15, 30, 45, and 60 min) and the addition of extra virgin olive oil (5 and 10%) on the phenolic content of tomato sauces was monitored using liquid chromatography coupled to tandem mass spectrometry. Concentration of phenolics in the tomato sauces decreased during the cooking process, with the exception of caffeic acid and tyrosol. The main degradation observed was the oxidation of quercetin, since the hydroxy-function at the C-ring of this flavonoid is not blocked by a sugar moiety, unlike rutin. Higher levels of virgin olive oil in tomato sauce seemed to enhance the extraction of phenolic compounds from the tomato, leading to higher phenolic contents in the sauces. Thus, the food matrix containing the phenolic compounds plays a crucial role in determining their accessibility.

Caracterização e aceitabilidade de tomate seco

In this work evaluated the content of vitamin C and total carotenoid in tomatoes fresh and dehydrated for conserve, with posterior immersion in sauce, verifying its sensorial acceptability. Dehydration was performed in dryer with airflow at 70 °C to obtain a product with final moisture of 45%. Determinations were carried out ascorbic acid, soluble solids, acidity, sugars and carotenoid before and after the dehydration process. The dehydrated tomatoes had been immersed in three types of sauces (pepper sauce, oregano with parrot leaves sauce and garlic sauce) per 25 days. After this period, the dry tomatoes in conserve had been submitted to the sensorial analysis in the pate form, applying themselves preference test. The results had been showed that retention of vitamin C and total carotenoid in the dehydrated product showed retention of 14.0% and 44.3%, respectively, in tomatoes after the dehydration process. Among the formulation of canned t

Consumer Perception and Willingness to Pay for Local Food

A growing number of empirical studies recently investigated consumers' valuation for local food products. However, different aspects related to the local food consumption still remain vague or unexplored. As such, the objective of the present research is to fulfill the existing literature using a mixed methodological approach for the investigation of consumers' preferences and Willingness to Pay (WTP) for local food products. First of all, local food is still a blurred concept and this factor might be source of individuals' misperception for the local origin meaning. Therefore, a qualitative research has been performed in order to investigate the meaning and the perception of the local food in the Italian food market. Results from this analysis have been used as inputs for the building of a non-hypothetical Real Choice Experiment (RCE) to estimate consumers' WTP for locally and organically produced apple sauce. The contribution of this study is three-fold: (1) consumers' valuation for the local origin is interpreted in terms of regional borders, over the organic food claim in case of an unusual food product in the area of interest, (2) the interaction between individuals' personality traits and consumers’ preferences for local and organic foods is analyzed, (3) the role of Commitment Cost creation in consumers' choice making in case of uncertainty due to the use of a novel food product and of an unconventional food claim is investigated. Results suggest that consumers are willing to pay a higher price premium for organic over locally produced apple sauce, possibly because of the presence of a regulated certification. In accordance with Commitment Cost theory, the organic label might thus decrease consumers' uncertainty for the features of the product in question. Results also indicate that individuals' personality can be source of heterogeneity in consumers' preferences.

Estudios de eficiencia en el uso de la luz y estimaciones de biomasa en cultivos energéticos de Salix sp. en Central New York, USA

La productividad es un factor importante que influye en la viabilidad económica de un cultivo energético de sauce y maximizarla se convierte en un tema primordial. Esta investigación está directamente relacionada con dicha característica. La productividad varía según los clones cultivados, que pueden ser mejorados y seleccionados genéticamente. Los programas genéticos requieren de una información previa (productividad media en función del porte y número de los tallos, características de las hojas, resistencia a las plagas, etc.) que ayudará a obtener clones más productivos y resistentes. Por ello, nuestra investigación consta de dos estudios: (1) Evaluación de la eficiencia del uso de la luz o LUE (Light Use Efficiency). El incremento de biomasa y la eficiencia del uso de la luz (LUE) fue estudiado en 15 clones del genero Salix durante los meses de junio a septiembre de 2011 en Belleville (Central New York, USA). Los objetivos de este estudio fueron: (1) Evaluar la eficiencia del uso de la luz en la explicación a la variación en la producción de biomasa y (2) Determinar si existen diferencias significativas entre clones evaluando el índice de área foliar (LAI) y algunos componentes de las hojas (N, P, K,…). Se concluye que la variación de biomasa está relacionada con la cantidad de luz interceptada y con la eficiencia de su uso. Dicha información debe de ser transferida para ayudar a mejorar genéticamente los futuros clones a comercializar, con el fin de maximizar la productividad y aumentar la resistencia a plagas. (2) Estimación de biomasa a través de modelos de regresión. Los estudios de investigación relacionados con la productividad requieren estimaciones no destructivas de la biomasa aérea. Sin embargo, el nivel de precisión requerido y la inversión de tiempo son excesivos para operaciones comerciales con grandes extensiones (plantaciones de 10.000 ha). Por esta razón, se estudia el nivel de especificidad (específico, intermedio y general) en la toma de datos de campo sobre los mismos 15 clones (12 de ellos se pueden agrupar en 5 grupos según su genotipo origen) del genero Salix, empleados en el estudio anterior. Para todos los niveles estudiados se observaron diferencias significativas. Pero desde nuestro punto de vista, las diferencias obtenidas no son relevantes. Para validar los modelos finalmente seleccionados se calcularon los porcentajes de error entre la biomasa estimada por los modelos de regresión calculados y la biomasa real obtenida tras los pesajes de biomasa, todo ello se realizó para cada clon según nivel de especificidad. ABSTRACT Productivity is an important factor in the economic viability of a willow crop´s, therefore, maximize it becomes a major factor. This study is directly related to this feature. Productivity, among other factors, may vary depending on different clones, which can be improved and selected genetically. Genetic programs require prior information (average productivity, size and number of stems, leaf characteristics, resistance to pests, etc.) to help you get more productive clones resistant to local pests. Our research consists of two studies: (1) Evaluation of the efficiency of use of light (LUE, Light Use Efficiency). The increase of biomass and light use efficiency (LUE) was tested on 15 clones of the genus Salix during June and September 2011 in Belleville (Central New York, USA). The objectives of this study were: (1) evaluate the light use efficiency and its relationship with the variation in biomass production and (2) determine whether there are significant differences between clones evaluating the leaf area index (LAI) and some traits of the leaves (N, P, K). We studied the correlation with the light use efficiency. It is concluded that the variation of biomass was related to the amount of light intercepted and its efficiency. Such information must be transferred to help improve future genetically clones to market in order to maximize productivity and increase resistance to pests. (2) Estimation of biomass through regression models. Research studies related to productivity estimates require precision and non destructive biomass. However, the level of accuracy required and the investment of time are excessive for large commercial operations with extensions (plantations of 10,000 ha). Precisely for this reason, we study the level of specificity (specific, intermediate and general) in making field data on the same 15 clones (12 of them can be grouped into five groups according to their genotype origin) of the genus Salix, employees in the previous study. For all levels studied some significant differences were observed. But from our practical standpoint, the differences are not relevant. Finally, to validate the selected models, we calculated the percent of bias between estimated biomass (by the regression models) and real biomass obtained after the weighing of biomass, all this process was done for each clone by level of specificity.
