Advantages of sous-vide cooked red cabbage: structural, nutritional and sensory aspects

The comparison between equivalent cooking treatments should be applied in a systematic way. This study proposes a methodical way to provide cooked samples with similar firmness using two cooking treatments. In addition, the structural, nutritional and sensory properties of red cabbage cooked with sous-vide treatment in comparison with traditional cooking (boiling water) was evaluated. Changes in texture, color and anthocyanin content were measured in samples cooked with traditional cooking (for different times) and sous-vide (modifying time and temperature according to a Response Surface Methodology). Consumers described sensory properties and preferences between samples. Cryoscanning electron microscopy was used to study the samples microstructure. The firmness of samples, traditionally cooked for 11 min and preferred by consumers, was achieved in samples cooked with sous-vide treatment by optimizing of the cooking conditions (87 C/50 min or 91 C/30 min). Sous-vide treatment was preferred to traditional cooking by consumers. Sous-vide samples were more purple, more aromatic and tastier than traditionally cooked ones. The loss of anthocyanins in traditional cooking was twice that in sous-vide samples. Micrographs from different treatments showed different degrees of cell wall damage. Sous-vide treatment could be recommended as a treatment for the catering industry providing better quality products.Author Iborra-Bernad was supported by the Generalitat Valenciana under FPI (Researcher Formation Program) grant.

Comparison of Vacuum Treatments and Traditional Cooking Using Instrumental and Sensory Analysis

The purpose of this work was to compare carrots with similar firmness cooked by traditional cooking and two vacuum treatments: sous-vide (SV) and cook-vide (CV). As a first step, consumers determined the preferred level of firmness for carrots cooked by traditional cooking (boiling). This level corresponded to instrumental firmness of 2.8 N in phloem tissue and 4.1 N in xylem tissue. Response surface methodology (RSM) established the pairing conditions of time (22 to 78 min) and temperature (78 to 92 °C) to study the effect of both factors on the firmness of carrots with sous-vide and cook-vide treatments. In both treatments, the instrumental firmness of phloem and xylem samples was measured and modeled. No significant differences were found in firmness values between phloem and xylem tissue of samples cooked by vacuum treatments (CVand SV). For CV treatment, firmness decreased linearly with time and temperature, while for SV treatment it followed a second-order model. Based on the model, conditions of time and temperature to achieve the preferred firmness (2.8 N) were selected for both treatments. Finally, consumers compared the sensory properties of carrots cooked by traditional cooking, sous-vide, and cook-vide with paired comparison tests evaluating three pairs of samples. Carrots cooked by cook-vide were considered less tasty than sous-vide and traditional cooking carrots. Carrots using traditional cooking were firmer than those obtained with SV and CV treatments. Carrots cooked by traditional and sous-vide treatments were preferred to cook-vide ones for the taste.Consuelo Iborra- Bernad has received research grant from the Generalitat Valenciana.

Evaluation of Textural and Sensory Properties on Typical Spanish Small Cakes Designed Using Alternative Flours

[EN] The objective of this study was to evaluate the effect of wheat flour substitution with toasted corn, quinoa, and sorghum flours on the overall perception and texture of typical Spanish small cakes named madeleine. In order to evaluate these characteristics, a texture profile analysis (TPA) and a sensory analysis were carried out. TPA showed that the replacement of wheat flour by sorghum flour did not affect significantly texture parameters of cakes. Hedonic sensory tests were also conducted revealing that the cake prepared with sorghum flour was highly appreciated by the consumers as it got scores similar to traditional cakes made with wheat flour.Casas Moreno, MDM.; Barreto Palacios, VJ.; González Carrascosa, R.; Iborra Bernad, MDC.; Andrés Bello, MD.; Martínez Monzó, J.; García-Segovia, P.

Replacing Sugar in Ice Cream: Fruit Up® as a Substitute

Consumers desire new foods that are simultaneously delicious, indulgent, and healthy. In the last few decades, food companies have been interested in developing foods with reduced lipid and sugar contents. The aim of this investigation was to evaluate the impact of roasted apple ice cream made with sucrose and glucose versus Fruit Up® (natural fruit sweetener) using a dry oven and a moist oven to bake the apples used to make the ice cream mixture. A panel of 45 untrained consumers evaluated the products based on color, texture, sweetness, and apple flavor. The results of the sensory analysis showed that Fruit Up is a possible substitute for sugar in ice cream.García-Segovia, P.; Iborra Bernad, MDC.; Andrés Bello, MD.; González Carrascosa, R.; Barreto Palacios, VJ.; Bretón-Prats, J.; Martínez Monzó, J.

Effect of pH on Color and Texture of Food Products

[EN] Color and texture are important quality characteristics and major factors affecting sensory perception and consumer acceptance of foods. pH has an important effect on pigments (e.g., chlorophyll, carotenoids, anthocyanins, etc.) responsible for fruit color, vegetables and meat color. Also pH has a great impact on water-holding capacity and tenderness of muscle foods that are improved at acidic conditions below the typical pH of post-mortem. Moreover, during processing of food, the pH value affects many phenomena and processes such as protein properties as denaturizing, gelification, enzymatic activities, growth and mortality of microorganisms, germinating or inactivation of bacterial spores and chemical reactions such as the Maillard reaction. Thus, knowledge of pH effects and its control during processing is necessary to produce safe, high-quality and value-added products. The goal of this paper is to identify the effect of pH on color and texture of food products to show the importance of control this parameter.This study has been carried out with financial support from Ministerio de Innovacion (Spain).Andrés Bello, MD.; Barreto Palacios, V.; García Segovia, P.; Mir-Bel, J.; Martínez Monzó, J.
