Optical sensor data can be used to determine changes in anthocyanins, chlorophyll and soluble solids content (SSC) apple production. In this study, visible near-infrared spectra (729 975 nm) were transformed SSC values by advanced multivariate calibration models i.e., partial least square regression (PLSR) order test the substitution of destructive chemical analyses through non-destructive opti...

We report in-situ spectroscopic measurements of the structure and orientation of molecules in the interfacial region between the semi-soluble ionic solid CaF2 (fluorite) and an aqueous phase. This paper integrates a series of new experiments with earlier results to give a comprehensive understanding of this very dynamic interface. We employ the surface specific technique, vibrational sum-freque...

A lab-scale SBR equipped with a flat sheet membrane in submerged configuration that is named MSBR was used for the treatment of composting leachate. It was fed by biologically treated leachate with overall 70-1360 mg/L Chemical Oxygen Demand (COD). The values of pH, Electrical Conductivity (EC), and Dissolved Oxygen (DO) were monitored r...

Orange press liquor is a by-product generated by the citrus processing industry containing huge amounts of natural phenolic compounds with recognized antioxidant activity. In this work, an integrated membrane process for the recovery of flavonoids from orange press liquors was investigated on a laboratory scale. The liquor was previously clarified by ultrafiltration (UF) in selected operating c...

the physical and physiological characteristics of sarawak pineapple were studied at five different stages of growth from one to five months after anthesis. changes in fruit length, diameter, pulp color, pulp firmness, ph, total soluble solids, titratable acidity, ascorbic acid content and antioxidant activity were monitored. the sarawak pineapple exhibited a sigmoid growth pattern during fruit ...

background: an essential oil is a liquid that is generally distilled from the leaves, stems, flowers or other elements of a plant. objective: cumin (cuminum cyminum l.) essential oil (ceo) was analyzed to determine oil component. antifungal effect of ceo was determined by in vitro technique. in second stage, effect of different concentrations of ceo by pdm on postharvest life of strawberry (fra...

nitrogen foliar spray is one of the most important components in fertilizing programs for citrus in iran, as it can reduce nitrate leaching. the goal of this research was to determine the most effective concentration of foliar urea application on “thamson navel’’ orange trees, for achieving the highest yield. foliar sprays were carried out, in two stages with total concentrations of 0.4, 0.8 an...

Isotonic drinks can replace body fluids quickly because they contain electrolytes needed by the body. This study uses young coconut water as primary raw material with addition of pineapple juice to improve taste and nutritional value isotonic drinks. aimed determine characteristics adding different formulations sweeteners. used a factorial block randomized experimental design consisting two fac...

In this experiment the effect of edible coating (apricot gum) was used to extend the shelf life of apple slices. The edible coating was applied at different concentrations i.e. 0.5, 1, 2 and 3%. Physicochemical characteristics of edible coated apple slices were analyzed at different time intervals. The analysis was carried out for 12 days with an interval of 4 days. Results showed that the trea...
