- Abstract:
- ... Modified atmosphere packaging (MAP) has been widely known to delay the postharvest fruit senescence; nevertheless, its effect on antioxidant activity and cell wall metabolism of wolfberry fruit is largely unknown. The present study investigated the impact of elevated CO₂ on the quality attributes and cell wall degradation of wolfberry fruit during storage. The results showed that 10% CO₂ better ma ...

- Abstract:
- ... This study was conducted to understand the mechanism of wheat yield decrease under drought stress and the role of CO₂ in modulating physiological and metabolic drought effects. Wheat was grown under ambient and elevated CO₂ (400 and 800 ppm, respectively), and plants were subjected to drought stress prior to anthesis. Photosynthetic rate (An), stomatal conductance (Gs), transpiration rate (E) and ...

The present study aims to increase the efficiency of a resource from waste to health by valorisation of it through cleaner, eco-friendly and less energy-consuming technical processes such as microwave-asissted (MAE) and supercritical fluid (SFE) extractions. On the other hand, optimization of the processes have been applied utilizing multivariate statistic technique such as Response surface Method ...

- Abstract:
- ... The incidence of UV-B radiance on the surface of the earth has been intensifying in the tropics of the southern hemisphere. However, little is known about its effect on tropical trees, especially on sun-tolerant versus shade-tolerant plants. For this study we used two ecotypes of the tropical tree Paubrasilia echinata. These ecotypes diverge among themselves in relation to leaf morphology and ecol ...

- Abstract:
- ... Mesophyll conductance (gₘ), the diffusion of CO₂ from substomatal cavities to the carboxylation sites in the chloroplasts, is a highly complex trait driving photosynthesis (net CO₂ assimilation, AN). However, little is known concerning the mechanisms by which it is dynamically regulated. The apoplast is considered as a ‘key information bridge’ between the environment and cells. Interestingly, most ...

- Abstract:
- ... In the present work, the valorization of Nannochloropsis gaditana biomass is proposed within the concept of biorefinery. To this aim, high‐pressure homogenization (HPH) was used to break down the strong cell wall and supercritical fluid extraction (SFE) with pure CO₂ was applied as a first step to extract valuable compounds (such as non‐polar lipids and pigments). Extraction of the remaining resid ...

This study was conducted to elucidate the effect of calcium chloride (CaCl₂) spraying times and number of sprays on the changes in biochemical compounds of “Hayward” kiwifruit (Actinidia deliciosa) during storage as well as at the shelf life. The vines in two different commercial kiwifruit orchards were sprayed with CaCl₂ (15 g/L), one, two and three times in 35, 85 and 125 days after full bloom. ...

- Abstract:
- ... In Spain and in southern east of Spain in particular, citrus production has predominantly focused on lemon, which is a fruit with great possibilities as a fresh-cut product for use in fruit salads and as garnishes for drinks or cocktails. Lemon slices have good stability during cold storage because of their antioxidant activity. Nevertheless, fresh-cut lemon slices, already present to a limited ex ...

- Abstract:

Our previous studies have shown that browning manifestation is influenced by the level of astringency of the fruit; the present work studies the implication of polyphenol oxidase activity and total antioxidant capacity. Astringent and n ...

The optimum conditions for supercritical CO₂ extraction were as follows: extraction pressure, 30MPa; extraction temperature, 45°C; dynamic extraction time, 60min; CO₂ flow, 25kg/h. The oil yield under the conditions proposed was ...

- Abstract:
- ... Storage of fresh horticultural perishables within the optimum range of low oxygen and/or elevated carbon dioxide atmospheres for each commodity reduces their respiration and ethylene production rates. However, outside this range respiration and ethylene production rates can be stimulated indicating a stress response, which can contribute to incidence of physiological disorders and increased suscep ...
