This study reports a characterization of the nutritional quality several vegetables belonging to Brassica genus and other species cultivated in central Italy. The aim this trial is investigate antioxidant capacity phytochemical content vegetable products during two consecutive years. sensorial investigated with measuring soluble solid (SSC), titratable acidity (TA) pH; by measurement total (TAC...

Red wine grapes require a constant follow-up through analytical chemistry to assure the greatest quality. Wet chemical procedures are time-consuming and produce residues that hard eliminate. NIR (near infrared radiation) spectroscopy has been referred as an accurate, rapid, cost-efficient technique evaluate quality in many fruit species, both field industry. The main objective of this study was...

The production of cherry tomato ( Solanum lycopersicum var. cerasiforme ) is negatively affected by harsh environmental conditions such as extremely high and low temperatures, wind hail damage, pest disease infestation. These factors delay maturity cause uneven ripening, fruit abrasion, blemishes, which consequently result in poor quality reduced shelf life. Preharvest bagging an environmentall...

Peach fruit quality is dependent on preharvest treatments and orchard practices. The aim of this study to evaluate the effects potassium silicon fertilization postharvest quality. Two peach cultivars (“Early Bomba” “Plagold 17”) were sprayed with three concentrations (K-Si) at set, stone hardening, physiological maturity stages. applied corresponded control (T0 = 0% K-Si) pulverized distilled w...

Enzymatic browning is one of the reactions influencing quality some fruit juices such as quince juice. Nowadays, there an increased demand for application antibrowning agents. This research was aimed at effects using each ethanolic and aqueous apple peel extracts (EAPE, AAPE) in two concentrations (0.3 3%) inhibitor agents polyphenol oxidase activity (PPO) juice their on index (BI), total solub...

The hyperspectral imaging technology is used to detect early-maturing pear’s effective acidity nondestructively, and effective prediction model is established. 145 pears’ hyperspectral images are obtained in the wavelength range of 400nm-1000nm. Total 145 pears are separated into the calibration set (77 samples) and prediction set (68 samples). Early-maturing pear’s effective acidity partial le...

An alumino-silicate zeolite, Linde Type-A (LTA) has been prepared from aluminium powder and sodium metasilicate by hydrothermal process. The zeolite was characterized by FTIR and X-ray diffraction (XRD) analysis and by measuring the surface acidity using KOH as adsorbate. The surface acidity of LTA zeolite varied greatly with varying synthesized conditions such as crystallization temperature, c...
