abstract in this study, fresh pistachio of 'ohadi' and 'akbari' cultivars expose to the uv-c radiation with a wavelength of 0, 3, 6 and 12 kj/m2, then located at temperature of 1 ± 3 degrees celsius for 45 days. properties or attributes, including weight loss, stiffness and sensory evaluation of fresh pistachio after 20 and 45 days storage were measured. results showed that pistachio nut weight...

this study evaluated the antibacterial and antioxidant effects of tamarind water solution on shelf life of silver carp ( hypophthalmicthys molitrix ) fillet during refrigerator storage. treatments of this study were unwashed samples (control), and samples washed with 1% and 2% tamarind water solution. microbial, physicochemical and sensory analysis including total viable count (tvc), peroxide v...

The effect of Cinnamomum zeylanicum essential oil (CZEO) at two concentrations (0.02% and 0.04% v/w) on chemical composition, pH, water activity (aw), lipid oxidation, color stability and sensory characteristics of Lyoner-type sausage stored at 4 ˚C for 40 days was investigated. The moisture content of the control sample was higher (p < 0.05) than CZEO incorporated samples, wh...

Background: Many common cancers, such as prostate, breast, and colon, are caused by harmful substances and compounds contained in processed foods, including nitrite-treated meats. The aim of this study was to investigate the possibility of replacing sodium nitrite with Monascus purpureus pigment in sausage and to assess its antimicrobial, antioxidant, color, and sensory properties. Methods: The...

Nevertheless, in order to respond to the economic and environmental criteria, hydrogen production and storage have to be improved. This work focuses on gaseous storage under high pressure (700 bar) using a type III vessel (figure 1) that is to say composed of a metal liner – which prevents gas diffusion – and of a composite laminate wrapped by filament winding – which is used as a mechanical st...

Cut dahlia (Dahlia Cav.) flowers have recently become popular in Japan, but their marketability is limited by poor vase life. During the postharvest period, senescence of petals initiates from outermost whorl and then proceeds into inner petals. We found that drawing resistances ‘Kokuchou’, ‘Nesshou’, ‘Saisetsu’ decreases with time because gradually detach ovaries. A reduction resistance occurr...

A protocol was developed to measure the glass transition temperature (Tg) of brown rice kernels using dynamic mechanical thermal analysis (DMTA). In order to accommodate the sample requirements of the dynamic mechanical thermal analyzer and prevent moisture loss during experiments, kernels were first wrapped with a thin layer of parafilm and then a thin layer of aluminum foil. The wrapped kerne...

The respiration of cut flowers of rose (Rosa hybrida L. ‘First Red’) and gypsophila (Gypsophila paniculata L. ‘Bristol Fairy’) increased exponentially with increasing respiration, with a Q10 value between 0 and 10°C of 3 for both flowers. The vase life of the flowers was negatively affected by simulated transport at higher temperatures whereas dry storage for 5 days at 0°C resulted in a vase li...
