Abstract “Grada de Viseu” is an indigenous hazelnut variety from Portugal, and it considered by the producers as most important in terms of production productivity. Therefore, aim this study was to assess influence harvest year (2017/2018/2019) location (Viseu/Faia) on some physical chemical properties Viseu,” namely biometric parameters, colour, true bulk densities, texture parameters (hardnes...

Characteristics of sugar snap and chocolate chip cookies, and hazelnut biscuits made from refrigerated and frozen dough were studied. Doughs were stored at 4 °C for 6 weeks and at –18 °C for 6 months, respectively. Physical characteristics of the biscuit samples such as spread, baking loss, surface colour and density were determined. Dough colour was not affected by storage time and temperature...

Pyrolysis essentially is the thermal decomposition of organic matter under inert atmospheric conditions or in a limited supply of air, leading to the release of volatiles and formation of char. Modeling of pyrolysis implies the representation of the chemical and physical phenomena in a mathematical form. In this study, Differential Evolution (DE) algorithm is applied and global optimum set of k...

The effect of some natural wastes (orange pomace, orange peel, lemon pomace, lemon peel, apple pomace, pear peel, banana peel, melon peel and hazelnut shell) on the production of xylanase from Trichoderma harzianum 1073 D3 has been studied and maximum activity has been observed on melon peel (26.5 U/mg of protein) followed by apple pomace and hazelnut shell. Also, molasses could be used as an a...

In this paper the benefits of using highly integrated millimeter-wave FMCW radar systems for industrial and security imaging applications are discussed. A 240 GHz wideband transceiver MMIC with on-chip antennas is presented and first non destructive testing measurements of packed hazelnut chocolate are shown. The radar system covers the frequency band from 204GHz to 265GHz.

Abstract Certain species of acorn- and nut-feeding weevils, Curculio spp. (Coleoptera: Curculionidae), have become significant insect pests cultivated hazelnuts (Corylus spp.) (Fagales: Betulaceae) worldwide. The significance weevils that feed on injure is increasing as countries such the United States China continue to develop hybrids hazel plants increase their hazelnut production. This revie...

Hazelnut providing the macro-and micronutrients is a constituent of healthy diet. Hazelnut, one most consumed treenut, produced in different countries. The geographical origin influences chemical composition and biological activity several plant foods. purpose this study to evaluate composition, antioxidative capacity total phenolic content hazelnut kernels obtained from countries, including Az...

________________________________________________________________________________ Abstract This study was performed to investigate the effects of different oils in the diets of laying quail on their performance, egg quality, serum lipids and fatty acid composition of egg yolk. One hundred and ninety two 12-wk old Japanese quail were allocated to eight groups with two replicates containing 12 qua...
