While shellfish species are widely consumed due to their nutritional advantages, they are also among the top eight food items for food-borne allergies. Five distinct thermal processing techniques were applied to the crustacean to investigate the tropomyosin level variations caused by heat processing. Fresh shrimp and prawns were utilized as controls for the determination of allergen-encoding genes. Prior to molecular analysis, the proximate composition and acidity of raw and processed samples were also performed. The yield and purity of DNA were also determined. Melting curve and gel electrophoresis tests verified the existence of allergen-coding genes. Thermal processing procedures affected the proximate composition, particularly the total protein and fat concentrations, according to the findings. Following the heat treatment, the pH levels decreased, particularly in the grilled samples. There were also significant differences in the quantity and quality of the extracted DNA. Regardless of crustacean species, the tropomyosin-encoding gene was detected in both fried and grilled samples. These findings demonstrated that RT-PCR identification and validation of the crustacean allergy gene by gel electrophoresis might be a reliable approach for the thermally treated shrimp and prawn samples. This study shows that investigating the allergen coding gene might provide a viable way for detecting food-borne allergens in other thermally processed food items, which are becoming more concerned about food safety.

En un invernadero del Centro Internacional de Agricultura Tropical, CIAT, Cali (Colombia) se evaluó la aplicación de cinco inóculos de hongos micorrícico arbusculares, HMA: Kuklospora colombiana, Gigaspora margarita, Glomus manihotis y la mezcla de estos con y sin esterilización, en sustrato sin desinfectar (SD) y desinfectado (D) sobre variables de rendimiento (biomasa aérea y radical, longitud radical), colonización por HMA y concentración foliar de nutrientes en la gramínea Melinis minutiflora Beauv., con el objetivo de seleccionar los inóculos más eficientes. Se utilizaron como unidades experimentales materos de 13.5 x 16.0 x 14.0 cm. El sustrato empleado fue suelo procedente de un Inceptisol con baja disponibilidad de nutrientes, tamizado y mezclado con arena. Los inóculos de Gi. margarita y Gl. manihotis presentaron los mejores resultados en la acumulación de biomasa aérea y radical, longitud radical, porcentaje de colonización micorrícica y concentración de elementos. Kuklospora colombiana presentó efectos inhibitorios sobre las variables evaluadas. La condición del sustrato SD favoreció la acumulación de biomasa aérea y radical y la concentración de fósforo (P) en la biomasa aérea, además, estimuló la longitud radical de M. minutiflora. La concentración de N, K, Ca y Mg en la biomasa aérea fue mayor en el sustrato D. Los resultados muestran que Mellinis minutiflora con inoculación HMA es promisoria para la recuperación de suelos degradados. | The effect of five inocula of arbuscular mycorrhizal fungi (AMF) on the grass Melinis minutiflora Beauv. was investigated under greenhouse conditions at the International Center for Tropical Agriculture (CIAT), Cali, Colombia, with the aim of selecting the most efficient AMF inocula. Non-disinfected (ND) and disinfected (D) substrates were studied. Inocula were: Kuklospora colombiana, Gigaspora margarita, Glomus manihotis and a mixture of those three species of AMF with and without sterilization. Yield parameters were aerial and radical biomass, root length, mycorrhizal colonization and N, P, K, Ca, and Mg concentrations in the aerial biomass. Pots measuring 13.5 x 8.0 x 14.0 cm were used as experimental units. Inceptisol soil, with low nutrient availability, previously sieved and mixed with sand was used as substrate. Gi. margarita and Gl. manihotis inocula showed the best results in the accumulation of aerial and root biomass, root length, mycorrhizal colonization and concentration of elements in the aerial biomass, while Ku. colombiana presented inhibitory effects on the variables evaluated. ND substrate condition increased accumulation of aerial and radical biomass and P concentration in the aerial biomass, also stimulated root length of M. minutiflora. Aerial biomass had higher concentrations of N, K, Ca, and Mg in D substrate. Mellinis minutiflora is a promising grass species for rehabilitation of degraded soils in combination with arbuscular mycorrhizal fungi inoculation.

This study aimed to evaluate the biochemical and nutritional profiles of three cauliflower cultivars—Valentena, Carotena, and Snow White—focusing on chlorophyll, carotenoids, anthocyanins, vitamin C, flavonoids, phenolics, and antioxidant activity. Uniform curds were harvested at 60 days post-sowing from Baratia, Dumuria, Khulna, and analyzed at Khulna Agricultural University. Valentena exhibited the highest chlorophyll content (40.06±0.39 µg/100g FW chlorophyll a, 28.98±3.35 µg/100g FW chlorophyll b), superior lycopene (8.71±0.38 µg/100g FW) levels. Carotena showed the highest total carotenoid content (60.52±1.76 µg/100g FW) and β-carotene (26.99±0.44 µg/100g FW), while Snow White had the lowest values across most parameters. Valentena also led in anthocyanins (101.56±3.9 mg/L FW) and total flavonoids (79.56±10.36 mg/100g FW), with Carotena having the highest vitamin C content (60.05±2.93 µg/g FW). DPPH assays indicated that Valentena showed the most effective antioxidant (IC50 = 43.65±3.56 mg/mL FW), followed by Carotena and Snow White. Hierarchical clustering and pricipal component analysis (PCA) revealed distinct biochemical profiles: Valentena and Carotena shared similarities in carotenoids and antioxidant activity, whereas Snow White differed significantly. Linear discriminant analysis identified lycopene, chlorophyll b, and β-carotene as major differentiators, highlighting the diverse nutritional and antioxidant properties of these cauliflower varieties. The findings highlight the potential of Carotena and Valentena for health-conscious consumers seeking nutrient-rich, antioxidant benefits in functional meals.

The paper presents tests connected to the torrefaction of agro-biomass residues as a case of biomass valorisation. The aim of the work is to compare the changes in energy and chemical properties of millet stalk (Panicum miliaceum L.) before and after the torrefaction process. The torrefaction of the millet stalk was done by using a scale reactor in two temperatures, 275oC and 300oC, in an N2 atmosphere. The millet stalk torrefied at 300oC has more promising parameters, i.e., higher heating value HHV 24,57 MJ/kg, the content of carbon 64,90% and energy density 1,42 compering to biochar produced at 275oC - 22,57 MJ/kg, 60,90% and 1,31 respectively. The results showed that torrefaction improves the parameters of the millet stalk for higher-quality biofuel, which can be used for heat generation.

Hungary and Turkey have a considerable share in world wheat markets. In 2018, Hungary’s export value of wheat and wheat flour reached to 411 million euros and it formed 32 per cent of overall cereal & milling industry export value of the country. Export value of Turkey for the same commodities was 875 million euros in the same period and it formed 77 per cent of total cereal & milling industry export value (International Trade Centre, 2019). Considering their potential and recent upward trends in trade, this study aims to determine the competitiveness of the wheat sectors in Hungary and Turkey. The study examines the competitiveness level of both countries by using Balassa’s Revealed Comparative Advantage index and Michaely index. The examination range covers the 10-year period between 2009 and 2018. Majority of data in this work was obtained and derived from International Trade Centre database. According to analysis results, Hungary has a higher degree of specialization vis-a-vis Turkey.

The oleaster (Elaeagnus angustifolia L.), also known as wild olive, is a small fruit with three parts: the outer peel or exocarp layer, the edible part or mesocarp layer, and the inner seed or endocarp layer. The mesocarp layer is rich in essential vitamins and has great potential for use in various food products. The flour made from the mesocarp layer has a moisture content of 8.99%, an ash content of 2.66%, a fat content of 0.55%, a protein content of 5.99%, a crude fiber content of 3.32%, and a total dietary fiber (TDF) content of 26.36%. The TDF content is divided into insoluble dietary fiber (IDF) and soluble dietary fiber (SDF), which are 21.35% and 5.01%, respectively. The flour has color values of L*: 75.14, a*: 2.86, b*: 23.87, and a water activity value of 0.314. The water solubility, water absorption, and oil absorption are 67.33%, 4.91 g water/g sample, and 2.26 g oil/g sample, respectively. Additionally, the mesocarp layer contains minerals such as Mg, P, K, Ca, Fe, and Na. The mesocarp layer significantly affected the thermomechanical properties of wheat flour. As the substitution level of the mesocarp layer increased from 10 to 30%, the water absorption capacity, dough development time and stability time of the wheat dough significantly decreased. Specifically, the water absorption capacity dropped from 53.5% to 47%, dough development time reduced from 1.10 to 0.75 min, and stability time decreased from 8.90 to 2.25 min. Substituting a mesocarp layer in wheat flour can significantly improve product shelf-life due to slower retrogradation. The mesocarp layer is an functional ingredient in the food industry.

One of the most important impacts of the Covid 19 pandemic that broke out in China in the last months of 2019 was on the agricultural sector and, consequently, on the food supply. This situation manifested itself in an increase in food insecurity and food prices in countries around the world, and rising food prices highlighted the risk of undernourishment. The study attempted to statistically represent the impact of the pandemic on food security and food price increases in countries around the world. The study first compared the pre-pandemic and pandemic periods in terms of three basic indicators, such as food security, food prices, and undernourishment rates, and examined whether there was a significant difference between the two periods. Within the context of these three indicators, an attempt was then made to determine whether the negative impact of the pandemic was more severe in low-income countries. The results of the analysis showed that food prices, food insecurity, and undernourishment increased during the pandemic and that these impacts were relatively greater in developing countries. Therefore, the financial burden of these negative impacts associated with food supply was greater in developing countries.

Latin America is a diverse region that exhibits a high environmental, cultural and social wealth, likewise, this region presents a variety of ways according to their agricultural production conditions, cultures, practices and cultural, economic and political factors; this wide variety of factors influence the levels of agricultural productivity and hence competitiveness capacity of the region. The seed sector is different in each country and includes features, activities, dynamics and norms according to their local contexts, even within the same country coexist differences among seed crops sectors and / or regions. Considering that each system has its own characteristics, actors and interactions, it is necessary to propose studies to address knowledge through which the state of development of the sector in each country is determined. In this study a literature review and search for available data on seed systems in Brazil, Guatemala, Peru and Colombia is done to present factors and conditions on the state and development of the seed system in each of these countries. Overall, Brazil system shows an evolved system according to the Douglas (1982) classification criteria system. Colombia and Peru, have more developed systems for some crops than others, the most developed systems correspond to crops with higher economic interest while other cultures rely on informal systems such as self-sufficiency. In Guatemala, the supply of seeds is largely dependent on the farmers’ own production and public organizations through programs aimed at supporting small farmers | América Latina es una región que posee una gran riqueza ambiental, cultural y social, con sistemas variables de agricultura según sus condiciones de producción, cultivos, y factores culturales, económicos y políticos.

El sector de semillas es diferente en cada país y posee características, dinámicas y normas propias según sus contextos locales, incluso, dentro de un país coexisten diferencias entre los sectores semilleros entre cultivos y/o regiones. Considerando que cada sistema tiene sus propias características, actores e interacciones, se hace necesario proponer estudios para abordar su conocimiento a través de los cuales se determine el estado de desarrollo del sector en cada país. En este estudio se realiza una revisión bibliográfica y búsqueda de datos disponibles referentes a los sistemas de semillas de Brasil, Guatemala, Perú y Colombia con el fin de presentar el estado y desarrollo del sistema en cada uno de ellos. En general, el sistema en Brasil muestra un sistema evolucionado según los criterios de clasificación de Douglas (1982). Colombia y Perú presentan sistemas desarrollados para algunos cultivos, especialmente los de tipos comercial de mayor interés. En Guatemala el abastecimiento de semillas depende principalmente de la producción propia de agricultores y/u organizaciones públicas mediante programas dirigidos al apoyo de pequeños agricultores

The aim of the experiment is to study in vitro regeneration efficiency of international potato center (CIP)-bred salt tolerant potato genotypes under salt stress condition and to identify effective potato genotype(s) for saline belt areas of Bangladesh. An in vitro shoot bioassay of eight CIP-bred potato genotypes viz. CIP 102, CIP 106, CIP 111, CIP 117, CIP 124, BARI Alu 72 (CIP 139), and BARI Alu 73 (CIP 127) and CIP 136 were used. In this study, single node of these genotypes was cultured in MS media supplemented with 0, 80, 100, 120, 140 and 160 mM NaCl. Among the eight genotypes, BARI Alu 72 (CIP 139) showed the highest tolerance against salinity up to 160 mM NaCl (14.61 dS/m) for all studied parameters (except shoot and root initiation) with the highest plant height (9.67 cm), leaves number (13.60), nodes number (9.50), root length (6.50 cm), roots number (7.80), fresh weight of shoot (536.1 mg) and root (205.60 mg). On the other hand, CIP 106 was found the most susceptible genotype against salinity showing its highest salinity tolerance up to 120 mM NaCl (10.96 dS/m) with maximum plant height (7.17 cm), leaves number (12.50), nodes number (6.50), root length (7.50 cm), roots number (9.7), fresh weight of shoot (572.3 mg) and root (250 mg). The experiment's findings corroborated CIP's findings that they were salt tolerant, as well as recommended for their cultivation suitability in saline-affected area in Bangladesh.

A research was carry out in Palmira (Valle, Colombia) to test the solarization (poliethylene mulch). The experimental design consisted in "random blocks" and ten treatments obtained from the following factors combination: soil solarization during 2, 4 and 6 weeks, chemical treatrnent (Dazornet), control, all of them with and without application of rabbit manure (2 kg). The plot size was 1.44 m2. The soil was inoculated with the mixture of four isolations of Rhizoctonia solani which were pathogenics to the tomato (Tropic Variety). Temperatures of 49.7oC and 44.8oC at 5 and 10 cm deep respectively were reached in the soil under solarization treatment. The control reached temperatures of 41.6 y 38.8oC at the same depths. Rhizoctonia population was reduced to 0.8 colony formation units (C F U) per 100 g of soil in the solarization treatment, during the first experiment (september to october 1987). In the second experiment (january to february 1988) the CFU was reduced to zero. The chemical treatment reduced the CFU to zero in both experiments. The control plots showed and average of 24.6 CFU during both experiments. The number of seedlings per row and the number of healthy plants (93% in both experiments) was greater in the soil under chemical and solarization treatment than the control treatment. This showed 52.3 % and 88.7% of healthy plants in both experiments. The plots where the manure was applied the number of plants per row decreased in 3.3 (solarization) and 15.3 % (chemical), during the first experiment. The second experiment showed that the number of plants per row increased in 19.2% and 9.5% to the same treatments. | En Palmira (Valle, Colombia) se comparó la solarización del suelo (cubrimiento con láminas de polietileno) durante 2, 4 y 6 semanas, con un producto químico (Dazomet) para la desinfestación de semilleros abonados con conejinaza (2 kg en 1.44 m2) y sin abonar, en presiembra. El suelo se inoculó con una mezcla de cuatro aislamientos de Rhizoctonia solani patogénicos a tomate variedad Tropic. En los suelos solarizados se alcanzaron temperaturas de 49.7 y 44.8 C a 5 y 10 cm de profundidad respectivamente y 41.6 y 38.8C en los testigos a las mismas profundidades. La solarización redujo la población de Rhizoctonia, en promedio, a 0.8 U.F.C (unidades formadoras de colonias) por 100 g de suelo, en el primer ensayo (septiembre-octubre de 1987) y a cero en el segundo ensayo (enero-febrero de 1988); el Dazomet la redujo a cero en los dos ensayos. El testigo presentó un promedio de 24.6 U.F.C para los dos ensayos. El número de plántulas por surco fue mayor en los suelos tratados (solarización y producto químico) lo mismo que el porcentaje de plántulas sanas (93 %), en los dos ensayos; el testigo presentó 52.3 y 88.7% plántulas sanas en los dos ensayos respectivamente. En los semilleros abonados el número de plántulas por surco fue menor en 3.3 (solarización) y 15.3 % (producto químico) para el primer ensayo, pero fue mayor, 19.2 y 9.5%, en el segundo ensayo.
