“…The results are similar to those reported by Aydin et al (2002) for Turkish mahaleb, by Aydin Aydin (2003) for almond nut and kernel, by Paksoy and Aydin (2004) for edible squash seed, and by Akinci et al (2004) for Juniperus drupacea fruits. The terminal velocities of the walnuts obtained in this study were higher than of the above mentioned agricultural materials.…”

“…In recent years, the variation of physical properties as affected by the moisture content have been studied in various nut crops such as castor nuts (Olaoye 2000), raw cashew nuts (Balasubramanian 2001), hazelnuts (Aydin 2002), Turkish mahalebs , arecanut kernels (Kaleemullah & Gunasekar 2002), groundnut kernels (Olajide & Igbeka 2003), almond nuts and kernels (Aydin 2003), shea nuts (Aviara et al 2005), pine nuts (Özgüven & Vursavuş 2005), African nutmegs (Burubai et al 2007), and olive fruits (Kılıçkan & Güner 2008). Koyuncu et al (2004) and Sharifan and Derafshi (2008) studied the mechanical behaviour of walnut cultivars under compression loading.…”

Altuntas E., Erkol M. (2010): Physical properties of shelled and kernel walnuts as affected by the moisture content. Czech J. Food Sci., 28: 547-556.The variations in physical properties such as the size dimensions, unit mass, sphericity, projected area, bulk density, true density, volume, coefficient of friction on various surfaces, and terminal velocity of shelled and kernel walnuts as a function of the moisture content were determined. With an increase in the moisture content, the sphericity, projected area, bulk density, volume, and porosity of shelled and kernel walnuts increased, whereas the true density linearly decreased. Studies on rewetted walnuts showed that the terminal velocity increased from 14.17 m/s to 15.50 m/s, and from 12.60 m/s to 14.35 m/s, for shelled and kernel walnuts, respectively. The static and dynamic coefficients of friction of shelled and kernel walnuts on chipboard and plywood surfaces also increased linearly with an increase in the moisture content.

“…The quantitative descriptors recorded were: stalk length (cm), fruit volume (cm 3 ), endocarp volume (cm 3 ), geometric mean diameter (mm), surface area of the fruit (cm 2 ), sphericity (%), the relative seed size with respect to the fruit, total soluble solids (°Brix), and titratable acidity (g of malic acid/100 g fresh weight). (Mohsenin, 1978;Aydin, 2003;Olajide and Igbeka, 2003;Vursavuş and Özgüven, 2004). Following Mohsenin (1978) and Baryeh (2001), fruit surface area (S) can be expressed as S = π D g 2 .…”

Thirty-one traditional cultivars [26 sweet cherry (Prunus avium L.), four duke cherry (Prunus × gondouinii Rehd.), and one sour cherry (Prunus cerasus L.)] from Sierra de Francia and Arribes del Duero in Central-Western Spain were surveyed and characterized agromorphologically. A total of 37 descriptors, mainly def ined by the International Plant Genetic Resources Institute and the International Union for the Protection of New Varieties of Plants were used to describe flowers, leaves, fruits and the tree itself over a 3 consecutive years. This made possible the unequivocal identification of 25 cultivars. A dendrogram gave a clear separation between the sour, duke and sweet cherry cultivars and showed existing synonymies and homonymies. This work is an important step in the conservation of genetic cherry resources in the province of Salamanca (Spain), which show distinctive and interesting agronomical characters such as low susceptibility to fruit cracking, high levels of soluble solids, early fruit maturity and great rusticity.Additional key words: cherry descriptors, conservation, endangered cultivars, fruit parameters, genetic resources, homonymies, synonymies. ResumenCaracterización agromorfológica de cultivares tradicionales españoles de Prunus avium L., Prunus cerasus L. y Prunus × × gondouinii Rehd.Veintiséis cultivares de cerezo (Prunus avium L.), un cultivar de guindo (Prunus cerasus L.) y cuatro cultivares del híbrido de ambos (Prunus × gondouinii Rehd.), originarios de las zonas de Sierra de Francia y de Arribes del Duero, en el centro-oeste español, han sido prospectados y caracterizados desde el punto de vista agromorfológico. Un total de 37 descriptores, la mayoría definidos por el International Plant Genetic Resources Institute y por la International Union for the Protection of New Varieties of Plants fueron usados para describir flores, hojas, frutos y el árbol durante un periodo consecutivo de tres años, permitiendo la inequívoca identificación de 25 cultivares. El dendrograma de relación entre cultivares elaborado permite diferenciar claramente los cultivares de cerezo, guindo e híbrido estudiados y muestra la existencia de sinonimias y homonimias. El trabajo realizado constituye un paso importante para la conservación de estos recursos genéticos presentes en la provincia de Salamanca (España) que muestran caracteres agronómicos interesantes y distintivos tales como baja susceptibilidad al rajado, altos niveles de sólidos solubles, maduración temprana y gran rusticidad.Palabras clave adicionales: conservación, cultivares en peligro, descriptores de cerezo, homonimias, parámetros de fruto, recursos genéticos, sinonimias.

“…Its kernel is an important source of energy (6 Kcal/g) and protein (15.64%). Seed kernel has oil content ranged from 35.27% to 40% and it is an important source of oleic acid (Aydin, 2003). Almond seeds are not only used as dietary supplements but also has various pharmacological properties such as anti-stress (Bansal et al, 2009), anti-oxidant (Pinelo et al, 2004), immunostimulant (Puri et al, 2000), lipid lowering (Spiller et al, 1998), and laxative (Sharma & Saamhita, 1981).…”

The aim of the present study was to investigate the efficacy of pneumatic separation method in separation of almond kernels from its cracked shells. The influence of air velocity, mixture feed rates, distance between mixture inlet and kernels outlet, angle of mixture supply into tunnel and repeat times of operation on separation efficiency was also studied in this study. Results of study revealed that the separation efficiency decreased with increasing feed rate, angle of mixture supply into tunnel and distance between mixture inlet and kernels outlet. The highest ƞ% was reported on 9.5 m/s velocity while the lowest amount was reported on the 6.5 m/s. Increasing in repetition times have significant effect on the separation efficiency and it was reported higher with higher repetition time. Mixture of kernels outlet analysis revealed that separation of shells with 20-30mm length give poor results and about 50% of the shells remained on kernels outlet.
