the effect of ca, zn and b foliar application (five g l-1) and their mixed applications as well as two harvest dates (1st and 15st of august) on ppo activity of two commercial asian pears (‘ks’9 and ‘ks’13) fruits at the time of harvest and during storage were investigated. results showed that the ppo activity increased from harvest time to three months after storage and then decreased. during ...

the use of natural extracts as one of good antioxidant source is increasing to improve fish quality. the present study aims at investigating antioxidant effect of orange peel extract on the quality of common carp fillet during refrigerated storage (4°c). fish fillets were treated by 0, 1 and 5 % concentration of orange peel extract, packed and then stored in refrigerator. chemical parameters (p...

Li-ion hybrid supercapacitors (LIHSs) have recently attracted increasing attention as a new and promising energy storage device. However, it is still a great challenge to construct novel LIHSs with high-performance due to the majority of battery-type anodes retaining the sluggish kinetics of Li-ion storage and most capacitor-type cathodes with low specific capacitance. To solve this problem, 3D...

The maize (Zea mays) spikelet consists of two florets, each of which contains three developmentally synchronized anthers. Morphologically, the anthers in the upper and lower florets proceed through apparently similar developmental programs. To test for global differences in gene expression and to identify genes that are coordinately regulated during maize anther development, RNA samples isolate...

The bacteriocins of lactic acid bacteria have considerable potential for biopreservation. The Lactococcus lactis strain PSY2 (GenBank account no. JF703669) isolated from the surface of marine perch Perca flavescens produced antibacterial activity against pathogenic and spoilage-causing Gram-positive and Gram-negative bacteria viz. Arthrobacter sp., Acinetobacter sp., Bacillus subtilis, Escheric...

In southeastern regions of the US, herbage systems are primarily based on grazing or hay feeding with low nutritive value warm-season perennial grasses. Nutritious herbage such as annual ryegrass (Lolium multiflorum Lam.) may be more suitable for preserving as baleage for winter feeding even with more intensive production inputs. Emerging in-line wrapped baleage storage systems featuring rapid ...

this project was carried out in order to study of possibity of uses from 4 hexyresorcinol for prevention of melanosis in cultured shrimp.treatments including of samples processed with 0.15% concentration of 4 hexylresorcinol and control samples. the samples were kept at -18oc. bacterial, chemical and sensory examinations were carried out for a period of six months. statistically significant dif...

in this study, thyme extract (0, 2 and 4% w/v) on the chemical quality of common carp surimi was investigated during refrigerator storage. samples were withdrawn at four 3 days intervals over a storage period of 15 days (0, 3, 6, 9, 12 and 15 days), and analyzed to determine the extent of deterioration by chemical tests  such as thiobarbitoric acid (tba), total volatile bases nitrogen (tvb-n) a...
