Electrodialysis with monopolar ion exchange membranes was used to reduce the acid content of pineapple juice. It is an electrochemical membrane separation process in which electrically charged membranes and an electrical potential difference are used to separate ionic species in the pineapple juice from other uncharged components. Several physico-chemical (pH, titratable acidity and soluble sol...

Color and other quality parameters of “Redglobe” grape (Vitis vinifera L.) berries were evaluated after treatment with brassinosteroid (BR) analogs. Three BRs analogs (24epibrassinolide, Triol, or Lactone) were applied at three concentrations (0.0, 0.4, or 0.8 mg·L−1), at the onset of veraison. A commercial formulation (B-2000 R ) was also applied, at a recommended rate of 0.06 mg·L−1. The test...

This work presents a new deep learning architecture, SpectraNet–53, for quantitative analysis of fruit spectra, optimized predicting Soluble Solids Content (SSC, in °Brix). The novelty this approach resides being an architecture trainable on very small dataset, while keeping performance level on-par or above Partial Least Squares (PLS), time-proven machine method the field spectroscopy. Spectra...

Temperature integration where high day temperatures are compensated by lower night temperatures is one strategy that can be used to reduce energy consumption in greenhouses. Crop tolerance to temperature variation is a prerequisite for using such a strategy. Greenhouse experiments were conducted on tomatoes cvs, Capricia, Mecano and Cederico in order to investigate the effect of different day/n...

This study was conducted with the objective of testing the hypothesis that tomato fruits from organic farming accumulate more nutritional compounds, such as phenolics and vitamin C as a consequence of the stressing conditions associated with farming system. Growth was reduced in fruits from organic farming while titratable acidity, the soluble solids content and the concentrations in vitamin C ...

Plants were grown in two glasshouse compartments under two vapour pressure de®cit (vpd) levels: low vpd was obtained by increasing air humidity with a fogging system, and high vpd was obtained during sunny hours in a greenhouse where air humidity was not controlled. The mean value, of the six driest hours of the day concerning the growing period of the fruits considered, was 1.6 kPa under low v...

An attempt was made to understand the changes in physicochemical quality (total soluble solids, titratable acidity, ascorbic acid, total sugars, total phenolics, anthocyanin content, and cupric reducing antioxidant capacity assay) and total volatile/aroma compounds of two cultivars of strawberry (Camarosa and Chandler) during storage at 5°C for 9 days at an interval of three days. Observations ...

Manure was collected from growing pigs (22–48 kg) fed one of 11 diets varying in total and available phosphorus content. Reduced phosphorus diets were amended with feed additives intended to improve availability of phytate phosphorus. Diets were replicated over three feeding periods resulting in 33 manure samples. Collected manure samples were diluted (final solids content approximated 2.4% tot...

The effects of salicylic acid (SA) and Putrescine (Put), on cut Gladioluswas studied. SA (0, 150, 300 and 450 mg l-1) and Put (0, 100, 200 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 192 Gladioluscut flowers in horticulture laboratory of agriculture faculty of...
