“…However, there were no significant changes in ascorbic acid content of mango "Guifei" (Wang et al, 2006) and chayote (Cadena-Iniguez et al, 2006) after 1-MCP treatment. β-carotene was little affected in 1-MCP treated "Spring Belle" peach fruits (Caprioli et al, 2009).…”

Problem statement:Mango is a tropical fruit that ripens very quickly; for this reason, there has been a continuous effort to develop postharvest technologies to extend its shelf life and quality. Among them, 1-Methylcyclopropene (1-MCP) is widely used because it inhibits the action of ethylene receptors. Approach: Changes in physicochemical parameters, bioactive compounds and cell wall degrading activities were evaluated during storage and ripening of fresh whole mangoes treated with 1-MCP (750 nL L −1 ). Mature-green mangoes, cultivar Kent, untreated or treated with 1-MCP were evaluated for external quality, phytochemicals, Polygalacturonase (PG) and Pectin Methylesterase (PME) enzymatic activities during storage at 20°C for 2 weeks. Results: Concentration of ascorbic acid decreased during fruit ripening but 1-MCP-treated mangoes had reduced losses. Polygalacturonase and pectin methylesterase activities were reduced in the treated fruits as compared to untreated mangoes. Small changes in β-carotene were observed between treated and untreated fruits. Conclusion: 1-MCP affected the ripening process in "Kent" mango, reducing losses of ascorbic acid, this treatment is justified since it helps to maintain mango's nutritional value during its shelf life.

“…[1] This vegetable has a low lipid, protein, and calorie content, but it is an important source of minerals, amino acids, and vitamins. [1,2] Similar to other vegetables, chayote has a very high moisture content (>90% w.b. ), which can lead to extensive postharvest losses caused by chemical and microbial deterioration.…”

“…[1,3] Moreover, the viviparous development of chayote fruits during horticultural maturing adds to their limited shelf life in a fresh form representing serious disadvantages during shipping and transportation. [2] A feasible way to extend the shelf life of chayote is through the development of shelf-stable, reduced moisture products. [3,4] Convective drying is the most widely used technique for the production of dehydrated fruits and vegetables.…”

Effect of Osmotic Dehydration on Air-Drying Characteristics of Chayote

et al. 2010

In this study the effect of osmotic dehydration (OD) on the air-drying kinetics of chayote (Sechium edule (Jacq.) Swartz) fruits was investigated. Fresh and osmotically dehydrated chayote parallelepipeds (1 Â 1 Â 2 and 4 Â 4 Â 2 cm) were subjected to convective drying at air temperatures of 50 and 60 C, with air velocities of 1.5 and 2.5 m/s. The OD pretreatments were performed in 10 and 25% NaCl solutions (w/w) at 25 C during 3 h using a solution-tofruit mass ratio of 4:1. The use of higher air velocities notably accelerated drying rates as manifested through significantly higher drying rate constants estimated with Page's model, whereas no effect of temperature was observed. A previously reported analytical solution that considers both product shrinkage and variable diffusivity was generalized to describe the drying kinetics of food products with parallelepiped geometry. Selected drying experiments were then fitted to this solution using six different sets of model assumptions. Results indicated that product shrinkage is the main factor to be considered in order to estimate reliable values for diffusion coefficients. The OD pretreatments produced a significant reduction of the initial moisture content of chayote slabs before drying, thus allowing shorter drying time, which may lead to reduced energy consumption.

Traditional knowledge on integrated pest and weed management in chayote (Sechium edule (Jacq.) Sw.) crops from localities of Chiapas, Mexico Conocimiento tradicional sobre el manejo integrado de plagas y malezas en el cutivo del chayote (Sechium edule (Jacq.) Sw.) en localidades de Chiapas, México AbstractThis research was carried out in Villaflores and Villa Corzo, located in Chiapas State of Mexico. Specifically, throughout an ethno-agronomical approach, semi-structured interviews were designed and applied to the chayote producers who were selected by random routes. The results indicate the 57.89% of chayote producers in both municipalities, have allowed to control weeds in their crops, and being a higher proportion represented by Villaflores. Given these concerns, they prefer to control weeds throughout traditional methods, basically using mattocks with frequencies of 15 to 30 days after sowing or two to four times per cycle of crop production. Both pest and diseases are mainly controlled throughout chemical methods application. A preference to perform control among periods of higher rainfall or drought is not distinguished. A considerable percentage, which reaches 44% of the interviewed population among both municipalities, report they do not need to control pests and crop diseases. Key words:Crop cycle, ethno-agronomy, low-income families, participative -plant breeding, rustic methods, traditional agricultural technology. ResumenLa investigación se llevó a cabo en los municipios de Villaflores y Villa Corzo en el estado de Chiapas, a través de un enfoque etno-agronómico, se diseñaron y aplicaron entrevistas semiestructuradas a productores de chayote seleccionados por rutas aleatorias. Los resultados indican que el 57.89% de los productores de chayote de ambos municipios controlan las malezas en sus plantaciones, siendo mayor la proporción en Villaflores. Para controlar las malezas prefieren usar métodos culturales, fundamentalmente con la ayuda de coas o azadones y con frecuencias de 15 a 30 días después de la siembra o de dos a cuatro veces por ciclo de producción del cultivo. Las plagas y enfermedades se controlar mayoritariamente a través de métodos químicos, sobre todo en Villaflores durante la fase de fructificación. No se distingue una preferencia a realizar el control entre las épocas de mayores precipitaciones o durante la sequía. Un porcentaje considerable, que llega a alcanzar 44% del total de la población entrevistada entre ambos municipios, refieren que no necesitan controlar las plagas y enfermedades del cultivo.Palabras clave: Ciclo del cultivo, etno-agronomía, familias de bajos ingresos, mejoramiento vegetal participativo, métodos rústicos, tecnología agrícola tradicional.
