Fruit Wine Obtained from Melon by-Products: Physico-Chemical and Sensory Analysis, and Characterization of Key Aromas by GC-MS
About 20% of fresh fruits and vegetables are rejected for not meeting the superficial aesthetic standards (color, shape, and size). Part of the food production is not used in the human food chain. The transformation of these fresh products into novel re-valuable ones is a challenge for a sustainable food industry. This research studies an alcoholic fermentation fruit-based wine from two melon (Cucumis melo L.) cultivars: Jimbee® (smooth and yellow skin with orange flesh) and Okashi® (netted yellow-orange skin with pale green flesh). The melon juice (must) was fermented by Saccharomyces cerevisiae and enriched in sucrose and organic acids to achieve alcoholic fermentation, acidity, and flavors, obtaining a fruity-flavored and dry melon-based wine with 10° alcoholic grade, in both melon cultivars. The volatile compounds were measured by GC-MS and the odor activity value (OAV) was calculated. The Jimbee and Okashi melon wines increased their aromatic profile due to an increment in medium-chain fatty acid ethyl esters such as ethyl hexanoate, ethyl octanoate, and ethyl decanoate (OAV > 1), which contributed to the fruity aroma. Other volatile compounds such as ethyl 9-decenoate and phenethyl acetate (OAV > 1) appeared in the Okashi wine, which brought a floral aroma. For sensory evaluation (40–100), the Jimbee cultivar, with its orange flesh, scored 68.2 and the Okashi cultivar, with pale green flesh, scored 82.8, which was the preferred melon-based wine. This is an example of a circular economy model to produce a fruit-based wine with commercial potential and satisfactory sensory evaluation.This research was funded by RTI2018-099139-B-C21 project from Ministry of Science and Innovation (Spain)—National Research Agency (MCIN/AEI/10.13039/501100011033) and by “ERDF A way of making Europe”, of the European Union and by 21645/PDC/21 project from “Fundación Séneca” of Murcia Region (Spain).

Functional food obtained from fermentation of broccoli by-products (stalk): Metagenomics profile and glucosinolate and phenolic compounds characterization by LC-ESI-QqQ-MS/MS
This research revalues broccoli stalk by-product as a novel fermented health food, using its autochthonous microbiota. Broccoli stalk slices were packed into glass jars, brine was added (6% w/v), and two dressings were studied: garlic, and mustard seeds. No dressing was used as control. Natural fermentation was carried out at 25 ◦C for 6 days followed by a further 6 days storage at 4 ◦C. The identification of individual glucosinolates and phenolic compounds was performed by LC-ESI-QqQ-MS/MS. At day 3, the highest content in functional compounds such as glucoerucin and indolic glucosinolates as glucobrassicin, 4-methoxy-glucobrassicin and 4- hidroxy-glucobrassicin, and phenolic acids and flavonoids as sinapic acid, 4-O-feruloyl quinic acid and quercetin-3-O-diglucoside was found. At day 6, the broccoli stalks reached the maximum counts in lactic acid bacteria (>8 log cfu g- 1), remaining stable until day 12 at 4 ◦C, including as the main genera Lactobacillus and Leuconostoc. Metagenomic analysis identified 1009 bacteria genera; Latilactobacillus sakei was the most predominant lactic acid bacteria species, followed by Lactobacillus curvatus, Leuconostoc kimchi and Leuconostoc carnosum. This is an example of a vegan and functional food product, based on a circular economy model, using broccoli by-products.This research was funded by RTI2018-099139-B-C21 from Ministry of Science and Innovation - National Research Agency (MCIN/AEI/10.13039/501100011033) and by “ERDF A way of making Europe”, of the “European Union”.

La gimnasia estética de grupo, un nuevo modelo de competición
The purpose of this study is to review the literature on the historical origins, the technical characteristics and the key aspects of the regulation of a new and relatively unknown sport; the Aesthetic Group Gymnastics (GEG). This sport, which origin is in the Nordic countries, especially Finland and Sweden in the 18th century, serves the society to especially encourage women to physical activity and maintain it over time. This call is still in force, and for about 10 years was introduced in our country and there is a considerable increase in the practice of the same among the female children and adolescents. This sport is implanted in Spain in response to the strict requirements of the International Regulations that gives priority to the health aspects. The GEG is defined as a sport based on the stylized and natural body movement, which combines and enhances qualities like dynamism, rhythm and harmony of movements performed with economic and natural use of force. It is an expression, art and feeling become competitive sport. All of this done by a group of athletes flowing aesthetic and synchronized movement. We analyse the technique and the most important characteristics of this sport that allows to understand the differences between itself and the rhythmic gymnastics.El propósito de este trabajo es realizar una revisión bibliográfica sobre los orígenes históricos, las características técnicas y los aspectos claves del reglamento de una modalidad deportiva relativamente desconocida y novedosa como es la Gimnasia Estética de Grupo (GEG). En este contexto, la GEG originaria de los países nórdicos, especialmente Finlandia y Suecia en el siglo XVIII, sirve a la sociedad para motivar especialmente a las mujeres a la práctica de actividad física y mantenerla en el tiempo. Aún está vigente esta llamada, y desde hace unos 10 años se introdujo en nuestro país existiendo un incremento considerable en la práctica de la misma entre la población infantil y juvenil femenina. Se implanta en España atendiendo a las exigencias estrictas del Reglamento Internacional, que priman los aspectos saludables. La GEG se define como una disciplina deportiva basada en el movimiento estilizado y natural del cuerpo, que combina y realza cualidades como el dinamismo, el ritmo y la armonía de los movimientos realizados con el uso económico y natural de la fuerza. Es expresión, arte y sentimiento convertido en deporte de competición. Todo ello, realizado por un grupo de deportistas del que fluye un movimiento estético y sincronizado. Analizaremos su técnica y se detallarán las características más importantes de este deporte que lo lleva a diferenciarse de la gimnasia rítmica deportiva
Reusable plastic crates (RPCs) for fresh produce (case study on cauliflowers): Sustainable packaging but potential salmonella survival and risk of cross-contamination
The handling of fresh fruits and vegetables in reusable plastic crates (RPCs) has the potential to increase the sustainability of packaging in the fresh produce supply chain. However, the utilization of multiple-use containers can have consequences related to the microbial safety of this type of food. The present study assessed the potential cross-contamination of fresh cauliflowers with Salmonella enterica via different contact materials (polypropylene from RPCs, corrugated cardboard, and medium-density fiberboard (MDF) from wooden boxes). Additionally, the survival of the pathogenic microorganism was studied in cauliflowers and the contact materials during storage. The life cycle assessment (LCA) approach was used to evaluate the environmental impact of produce handling containers made from the different food-contact materials tested. The results show a higher risk of cross-contamination via polypropylene compared with cardboard and MDF. Another outcome of the study is the potential of Salmonella for surviving both in cross-contaminated produce and in contact materials under supply chain conditions. Regarding environmental sustainability, RPCs have a lower environmental impact than single-use containers (cardboard and wooden boxes). To exploit the potential environmental benefits of RPCs while ensuring food safety, it is necessary to guarantee the hygiene of this type of container.his research was funded by the Fondo Europeo de Desarrollo Regional/Ministerio de Ciencia e Innovación-Agencia Estatal de Investigación (FEDER/MICINN-AEI), project RTI2018- 099139-B-C21.

Modificación del método de las placas adhesivas amarillas para bioensayos de insecticidas en Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae)
[ESP] Se ha desarrollado un método para realizar bioensayos de resistencia a insecticidas en adultos de Bemisia tabaci (Gennadius), tanto en laboratorio y como en campo. El método es una variación de un sistema ya establecido, simplificando el equipo necesario para su elaboración.
Se han realizado bioensayos con este método en una población de laboratorio y en
poblaciones de campo, resultando en una relación significativa entre la concentración
del insecticida (endosulfán y metomilo) y la mortalidad.
La sencillez del método, el bajo coste del material necesario y su eficiente aplicabilidad en campo, lo hacen idóneo para programas de seguimiento de la resistencia a
insecticidas de las poblaciones de B. tabaci, siendo aplicable a otras especies.
[ENG] A field and laboratory bioassay method to test insecticide resistance for adults of
Bemisia tabaci has been developed. This method is a modification of a technique, by
simplification of the material required.
This method has been tested with a sensitive laboratory strain and with several field
populations, yielding in a significant relationship between the concentration of the insecticide (endosulfan and methomyl) and the mortality.
This easy, low-cost and accurate method is very useful for monitoring insecticide
resistance in field populations of B. tabaci, even of others species
