[ES] El aumento del consumo de grasas y carbohidratos, así como dulces, refrescos, productos industriales y snacks, junto con la disminución de la ingesta de alimentos saludables, y el sedentarismo en los niños, infl uyen en su salud. Hay que prestar especial atención a alimentos que forman parte del estilo de vida actual: “snack”, dulces, bollería o picoteo entre comidas por sus importantes repercusiones.

Intrusive thoughts about food may play a role in unhealthy eating behaviours. Food-related thoughts that capture attention can lead to craving and further intrusive thoughts (Kavanagh, Andrade, & May, 2005). We tested whether diverting attention to mental images or bodily sensations would reduce the incidence of intrusive thoughts about snack foods. In two experiments, participants reported their thoughts in response to probes during three 10 min periods. In the Baseline and Post-task period, participants were asked to let their mind wander. In the middle, Experimental, period, participants followed mind wandering (Control), thought diversion, or Thought Suppression instructions. Self-directed or Guided Imagery, Mindfulness-based Body Scanning, and Thought Suppression all reduced the proportion of thoughts about food, compared to Baseline. Following Body Scanning and Thought Suppression, food thoughts returned to Baseline frequencies Post-task, rather than rebounding. There were no effects of the interventions upon craving, although overall, craving and thought frequency were correlated. Thought control tasks may help people to ignore thoughts about food and thereby reduce their temptation to snack.

Experiments were undertaken to study effect of initial conditions on the expansion ratio of two grains in a laboratory scale, single speed, single screw extruder at Naresuan University, Thailand. Jasmine rice and Mung bean were used as the material. Three different initial moisture contents were adjusted for the grains and classified them into three groups according to particle sizes. Mesh sizes used are 12 and 14. Expansion ratio was measured at a constant barrel temperature of 190oC. Response surface methodology was used to obtain optimum conditions between moisture content and particle size of the materials concerned.

Vascular endothelial growth factor (VEGF) and bone morphogenetic proteins (BMP-7) are key regulators of angiogenesis and osteogenesis during bone regeneration. The aim of this study was to investigate the possibility of realizing sequential release of the two growth factors using a novel composite scaffold. Poly(lactic-co-glycolic acid) (PLGA)-Akermanite (AK) microspheres were used to make the composite scaffold, which was then loaded with BMP-7, followed by embedding in a gelatin hydrogel matrix loaded with VEGF. The release profiles of the growth factors were studied and selected osteogenic related markers of bone marrow stromal cells (BMSCs) were analysed. It was shown that the composite scaffolds exhibited a fast initial burst release of VEGF within the first 3 days and a sustained slow release of BMP-7 over the full period of 20 days. The in vitro proliferation and differentiation of the BMSCs cultured in the osteogenic medium were enhanced by 1 to 2 times, resulting from the additionally and sequentially release of growth factors from the PLGA-AK/gelatin composite scaffolds.

Overconsumption of snack foods has been linked to rising rates of obesity, with our ‘obesogenic’ environment and its abundance of palatable, high-calorie foods and associated cues especially implicated. However, it is clear that some individuals are particularly susceptible to overconsumption and weight gain. It was hypothesised that individuals sensitive to the rewarding properties of palatable foods, and associated stimuli, would show elevated consumption. Snack food intake was measured in 50 adults (mean age 34.5 years, BMI 23.9 kg/m2, 56% female) in a repeated measures design, both with and without a ‘food cue’. Trait (BIS/BAS scales), behavioural (computerised CARROT) and food reward were assessed. Sensitivity to food reward, but not generalised reward, was positively associated with snack food intake. This relationship was not affected by the presence of a food cue. Findings are discussed in the context of implications for weight management.

[eus] IKTekiko (Informazio eta Komunikazio Teknologiak) menpekotasuna, oso gai eztabaidatua da gaur egun, batik bat, guraso eta hezitzaileak kezkatzen dituena. Mugikorra aipaturiko teknologia horien barne dagoenez, horretaz egiten den erabilera ezagutzeaz gain, ikerketa honen helburu nagusia mugikorraren erabileraren eta errendimendu akademikoaren arteko korrelazio posible bat aurkitzea da. Horretarako, Euskal Autonomia Erkidegoari dagozkion Lehen Hezkuntzako 5. eta 6. mailetako 39 ikasleko lagina erabili da. Emaitzek, aipaturiko korrelazioa erakusten dute. Beraz, prebentzioaren garrantzia azpimarratzeko asmoz, menpekotasun jokaeraren garapena ekiditeko zenbait gako ematen dira.

A value-added extruded fish product was prepared with corn flour (80%) and fish (sciaenid) powder (20%), using a twin-screw extruder. The effect of different parameters like moisture, temperature, fish powder concentration, speed of the extruder and die-diameter on expansion ratio and crisp texture were studied. The storage characteristics of the final product were studied using three different types of packaging under nitrogen flushing. The study revealed that aluminum foil is the best packaging material to keep the product acceptable for more than three months.

Snack bar inside the old Student Union, Chapman College, Orange, California in the 1970s. Originally the manual arts building and bus repair garage for Orange Union High School. Building annex additions through 1975 increased the size to 19,680 sq. ft. Used as a student union by Chapman College. In 1996 the building became the Cecil B. DeMille Hall, housing the Film and TV department.

A experiência ficcional de Gérard Aké Loba — Kocoumbo, l’étudiant noir(1960), Les fils de Kouretcha (1970), Les dépossédés (1973) e Le sas des parvenus(1990), ancorada na dinâmica de culturas, no respeito e na honorabilidade do Eu e do Outro, centra-se na problemática da utopia e da construção da identidade pós-colonial. Considerando que a Literatura, enquanto sistema semiótico de produção e recepção de textos, se encontra vinculada a uma visão do mundo, iremos ver como nela se manifestam as relações entre o Ocidente (Europeu) e as regiões da África francófona (Costa do Marfim) no percurso das metamorfoses que conduzem ao Pós-Colonialismo. Procuraremos, de igual modo, problematizar a utopia, e também a distopia, comungando da proposta de Éric Aunoble2, para quem estas questões deverão ser compreendidas na sua relação com o tempo e com a historicidade presente por tentarem responder “aux attentes de leurs temps”.

Este trabalho teve por objetivo desenvolver nova formulação de snack por extrusão termoplástica a partir de mistura de farinhas de quirera de arroz e de bandinha de feijão, bem como avaliar o potencial nutricional, tecnológico e sensorial do novo produto. A farinha de bandinha de feijão carioca foi incorporada à farinha de quirera de arroz na proporção de 30%. O snack foi produzido em extrusora monorrosca, escala piloto. Os parâmetros de extrusão foram fixos, utilizando-se três zonas de extrusão com temperaturas de 40, 60 e 85 °C; velocidade do parafuso de 177 rpm; taxa de alimentação de 292 g.min-1, e matriz circular de 3,85 mm de diâmetro. A amostra de snack foi submetida a caracterizações fisicoquímica, tecnológica e sensorial. Observou-se efeito significativo da farinha de bandinha de feijão no aumento dos teores proteico e de fibras no snack obtido, quando comparada à farinha de quirera de arroz. Em relação às características tecnológicas do produto, obteve-se 0,17 g.cm-3 para densidade aparente, 7,75 para o índice de expansão e 435, g.f para a dureza instrumental. A formulação estudada foi aceita sensorialmente, com índice de aceitação para impressão global de 76%. Conclui-se que é possível produzir snacks por extrusão a partir da incorporação de 30% de farinha de bandinha de feijão à farinha de quirera de arroz, resultando em produto aceito sensorialmente e com adequado valor nutricional.
