This paper introduces the supply and value chains of the Colombian cocoa agribusiness. For such purpose, we have identified not only the agents, phases, stages and factors influencing the planting and harvesting of the product, but also the chocolate and confection production process, as well as the final consumption. Finally, the national production is described in the context provided by the international market. © The author; licensee Universidad Nacional de Colombia.

The effect of ultrasound power and temperature on the extraction of carbohydrates from agave was evaluated. Extraction kinetics of fructans (F), total carbohydrates (TC) and reducing sugars (RS) were obtained at different ultrasound powers (28-49 mW/mL) and temperatures (20-40 °C). The mass transfer coefficients of F, TC and RS were calculated and a model using the production functions of Cobb-Douglas was developed. Microstructural analysis was performed to evaluate the effect of ultrasound and temperature on carbohydrates extraction. Ultrasound and temperature had impact on F, TC and RS extractions. After 5 min, no increases in carbohydrates content were observed, showing an asymptotic tendency. Results showed a strong sonication effect in carbohydrate extraction at any extraction temperature. The maximum F, TC and RS contents were 7.2, 7.79 and 0.54 g/100 g d.m., respectively, at 49 mW/mL and 40 °C. The fructans volumetric mass transfer coefficients ranged from 0.0585 ± 4.2 × 10-4 to 0.0834 ± 12.51 × 10-4 s-1 (R2 = 0.86-0.92). An overall model was developed based on the Cobb-Douglas function, which was adjusted adequately to estimate the fructans extraction assisted with ultrasound (R2 = 0.954). Tissue structural changes were present due to cell-wall modifications and breakdowns of sonicated agave samples, which have enhanced the carbohydrates extraction. © 2015 The Institution of Chemical Engineers.

A simplified protocol to obtain transgenic tomato plants was established. The effects of culture media composition and Agrobacterium concentration were evaluated. The highest shoot-forming capacity index (5.6) was observed when leaf explants were cultured for 6 weeks with 2 mg·L -1 zeatin, 0.1 mg·L -11 indoleacetic acid, and 300 mg·L -1 timentin. Shoot elongation and root formation were performed in one step on growth regulator-free media. The highest percentage (82%) of fully developed plantlets was obtained when shoots were cultured for 4 weeks with 0.5· Murashige and Skoog (MS) media and 15 g·L -1 sucrose. A 100% of plant survival rate was observed after 4 weeks of being transplanted to ex vitro conditions followed by fruit production (15 fruits/plant) after 2 more weeks. Transient expression of β-glucuronidase was visualized in 100% of the leaf explants infected with Agrobacterium at an OD 600 = 0.5 and cocultured for 48 h with 2 mg·L -1 benzylaminopurine, 0.1 mg·L -1 naphthaleneacetic acid, and 100 mM acetosyringone. Stable transformation was confirmed by histochemical glucuronidase assay and polymerase chain reaction (PCR) analysis with a total efficiency of 19.1%. The complete protocol, from shoot induction to fruit production of soil-adapted transgenic plants can be accomplished in only 4 months, and it seems to be very useful for both micropropagation and genetic transformation purposes.

Bagasse Fibers of sugarcane were modified with dichloromethylvinylsilane and consecutively grafted with polystyrene. For unmodified fibers, TGA showed two maximum decomposition peaks at 320°C and at 370°C. For silanized fibers, the most stable stage was shifted to a higher temperature of 470°C and to 510°C for silanized and polystyrene grafted fibers. Young moduli of composites increased from 1.9 GPa for non-treated fibers to 3.3 GPa for silanized and polystyrene grafted fibers. © 2011, Sociedad Química de México.

The selection of oviposition sites by Aedes aegypti L. females was evaluated at El Fuerte, Sinaloa, Mexico. The study was done with ovitraps that contained paper strips as oviposition substrate, and water with spinosad, temephos, and water alone (check). Every week, oviposition substrates were removed and examined for egg laying. Results showed preference for spinosad with an oviposition activity index of 0.35 and for temephos 0.19 although the index was positive, on some sampling dates, they had repellent effect.
