<p>Uno de los principales inconvenientes para la exportación de la uchuva es la apropiada conservación del fruto para su consumo posterior; en tal sentido, la técnica de atmósfera modificada crea un microambiente que permite controlar las tasas de transpiración, respiración y la mayoría de reacciones de maduración en frutos almacenados. El estudio tuvo como propósito determinar la mezcla de gases y el tipo de película de empaque a emplear para una adecuada conservación de la uchuva. Se evaluaron frutos con y sin cáliz, tres tipos de película (polietilentereftalato-polietileno, polipropileno biorientadopolietileno y polyolefin) y cuatro concentraciones de gas (5% CO2 y 5% O2; 5% CO2 y 10% O2; mezcla comercial y mezcla ambiental) en un diseño estadístico de parcelas subdivididas. Para todas las unidades experimentales se emplearon 75 g de fruta empacados y almacenados a una temperatura de 7°C durante un mes; semanalmente se tomaron datos de variables físicas y químicas de tres unidades experimentales por cada tratamiento. Los frutos con cáliz conservaron mejor la firmeza y presentaron al término del ensayo un pH de 3,77, 13,1 °B y un índice de madurez de 9,3. La película de polyolefin mostró el mejor comportamiento y los frutos presentaron un pH de 3,8, 12,9 °B, índice de madurez de 9,9 y una pérdida de peso fresco de 0,75%. Para las distintas concentraciones de gas no se encontraron diferencias significativas. Los frutos almacenados sin empaque perdieron 4,58% de su peso inicial mientras los almacenados en empaque plástico y atmósfera artificial perdieron en promedio 0,48%.</p><p> </p><p><strong>Post-harvest behavior of cape gooseberry (Physalis peruviana L.) under active modified atmosphere conditions</strong></p><p>One of the main inconveniences for cape gooseberry export is the proper conservation of the fruit for further consumption; in that sense, the technique of modified atmosphere creates a microenvironment that allows the control of transpiration rates, respiration and the majority of maturation reactions in stored fruits.

All experiments used 75 grams of packed fruit stored at 7ºC for one month; physical and chemical variation data were taken from three experiments per each treatment weekly. Fruits with a calyx conserved better firmness and showed a pH of 3.77, 13.1 °B, and a maturity index of 9.3 at the end of the assay. The polyolefin film demonstrated the best behavior and the fruits showed a pH of 3.8, 12.9 °B, a maturity index of 9.9 and a loss of fresh weight of 0.75%. There were no significant differences for the distinct gas concentrations. Fruits stored without packaging lost 4.58% of their initial weight whereas those stored in plastic packaging and artificial atmosphere lost an average of 0.48%.</p>

Colombia is the main producer of cape gooseberry (Physalis peruviana L.), a plant known for its various consumption practices and medicinal properties. This plant is generally grown in eroded soils and is considered moderately tolerant to unfavorable conditions, such as nutrient-poor soils or high salt concentrations. Most studies conducted on this plant focus on fruit production and composition because it is the target product, but a small number of studies have been conducted to describe the effect of abiotic stress, e.g., salt stress, on growth and biochemical responses. In order to better understand the mechanism of inherent tolerance of this plant facing salt stress, the present study was conducted to determine the metabolic and growth differences of P. peruviana plants at three different BBCH-based growth substages, varying salt conditions. Hence, plants were independently treated with two NaCl solutions, and growth parameters and LC-ESI-MS-derived semi-quantitative levels of metabolites were then measured and compared between salt treatments per growth substage. A 90 mM NaCl treatment caused the greatest effect on plants, provoking low growth and particular metabolite variations. The treatment discrimination-driving feature classification suggested that glycosylated flavonols increased under 30 mM NaCl at 209 substages, withanolides decreased under 90 mM NaCl at 603 and 703 substages, and up-regulation of a free flavonol at all selected stages can be considered a salt stress response. Findings locate such response into a metabolic context and afford some insights into the plant response associated with antioxidant compound up-regulation.

Cape gooseberry (Physalis peruviana L.) is a South American fruit with high nutrient content, pleasant taste and antioxidant properties. However, its consumption in some countries is underеvalued. The aim of this study was to determine the nutritional composition of two genotypes of Cape gooseberry fruit produced in Bulgaria (CG-F and CG-P) and to compare it with imported Colombian fruits (CG-C). The samples were assayed for size, diameter, moisture, ash, titratable acidity, pH, protein, lipid, carbohydrate, natural pigments, and mineral content. Bulgarian genotypes were smaller in size than the imported Colombian fruits. The protein content (2.54-1.88 g/100 g) was relatively higher in the imported variety, compared with the locally produced fruit. Carbohydrate content (10.23-14.13 g/100 g) slightly varied between the genotypes. The sweetness of the fruit was due to the main detected sugars – sucrose, glucose and fructose. CG-F and GC-C genotypes had similar sweetness indices, and fruit taste was evaluated as sweet-sour. Pectin content did not exceed 1.85%; the cellulose content varied between 4.29% and 6.64%. Moreover, all investigated fruit had a low lipid content (below 1.00%). The total chlorophyll and carotenoids levels were the highest in the local genotype CG-P (3.62 and 22.36 µg/g). Potassium was the predominant macro-element in all genotypes; there were numerical differences in the rest of the minerals (Ca, Mg, Fe, Cu, Zn, Mn), while the heavy metals, Pb, Cd and Cr, were generally absent. Cape gooseberry fruit of Bulgarian origin was evaluated as a low-calorie nutrient, compatible with the imported Colombian fruit.

In order to review the literature on the ecophysiology of the cape gooseberry, it was found that this typical Andean plant, in Colombia adapts to a wide altitudinal range of the tropical cold climate, that is, between 1,800 and 2,800 meters above sea level (m a.s.l.), with optimal medium temperatures between 13 and 16°C and base (minimum) temperatures for stem and fruit growth are relatively low, 6.3 and 1.9°C, respectively, however it does not withstand temperatures <0°C. Likewise, the Andean conditions of the tropics such as high solar radiation and day lengths <12 hours, rather short, favor the flower initiation. 1,500-2,000 hours year-1 of direct sunshine are the most favorable for the size, quality and ripening of the fruit. Under field conditions in Bogota, a photosynthesis rate of A = 10.545 μmol CO2 m-2 s-1 and light compensation point Ic = 13.645 μmol photons m-2 s-1 was measured. As a plant with an indeterminate growth habit, a constant supply of water is essential, while high amounts or heavy rains after a dry season cause cracking of the fruits, just as the plant does not tolerate waterlogging for more than 4 days. Cape gooseberry is classified as moderately tolerant to salinity and 30 mMol NaCl curiously promote growth, having mechanisms, such as increased antioxidant activity, to protect against saline conditions.
