Fracture resistance of palm kernel seed to compressive loading

Quasi-static compression tests were carried out on treated single palm kernel seeds to study the effects of temperature, moisture content and loading position on the rupture force, deformation and toughness of the kernels. The levels of moisture content and temperature considered were 5, 7 and 10% w.b and 70, 90 and 110°C each at the horizontal and vertical loading position. Twenty palm kernel seeds were tested at...

Comparison of three methods of weight loss determination on maize stored in two farmer environments under natural infestation

Common methods of weight loss assessment in stored grain include the standard volume weight (SVW), count and weigh (C&W), the thousand grain mass (TGM) and the indirect with a conversion factor (CF) which have been used in varying storage environments. Apart from accuracy and reliability, practical application may limit their use in rural areas. Three of the methods: (SVW) or bulk density (BD), C&W and CF were...

Physical properties of honey products in Algeria

Honey is considered as the sweetened natural substance produced by mellifluous bees from the flowers nectar, plants parts or the insects excretions generally left on the same parts. Although Algeria possesses floral and climatic potentialities; it remains a small honey producer. Among analyzed samples,74% correspond to codex standards. This latter may increase if certain measures such as a national regulation including...

Phytochemical and mineral content of the leaves of four Sudanese Acacia species

The phytochemical and mineral composition of Acacia nilotica, Acacia mellifera, Acacia albidaand Acacia radiana were investigated. Both freshly expended and older leaves of the plant species were used for the analysis. Averagely, the phytochemical constituent of the plants are as follows: Tannins (0.18 to 0.21 mg ml-1), phenols (0.03 to 1.01 mg ml-1), saponins (0.11 to 0.23 mg ml-1) and...

Rheological and sensory properties of four kinds of jams

The rheological properties of four kinds of jams (Kewpie strawberry, Marmalade, Blueberry and ST. Dalfour) were determined by the rheometer of MCR101. It showed that all the jam samples belonged to non-Newtonian fluid model, with thixotropy and pseudoplastic. Three jams were fit for Herschel-Bulkley model, although yield stress existed in the samples at 25°C and was calculated as 25.07, 99.13 and 103.67 Pa for ST....

Effect of small-scale irrigation on the income of rural farm households: The case of Laelay Maichew District, Central Tigray, Ethiopia

Agricultural intensification is presumed to be a necessary pre-condition for the development of the agricultural sector in Ethiopia. To this end, various government and non-governmental organizations (NGOs), among others, initiated small-scale irrigation schemes throughout the country including the Tigray region. Despite these efforts, however, smallholder farmers particularly in the study area are found to be reluctant...

Climacteric ethylene is not essential for initiating chilling injury in tomato (Solanum lycopersicum) cv. Ailsa Craig

Chilling-sensitive fruit often produce a burst of ethylene when reconditioned at ambient temperature after cold storage. This has led some authors to propose that Chilling injury (CI) may be induced by post-chilling ethylene production. To test this hypothesis we examined two tomato (Solanum lycopersicum L.) mutants, non-ripening (nor) and ripening-inhibitor (rin) that do not produce climacteric ethylene. Fruits...
