Methodology assessment on melting and texture properties of spread during ageing and impact of sample size on the representativeness of the results

A large number of methods and instruments have been used for measuring the melting and texture properties of margarine and spread. All these methods assume that margarine or spreads are isotropic materials. Depending on the scale of the sample, such statement is sometimes questionable in particular when using miniaturized samples. This paper gives an overview of the methods adopted and evaluates its suitability to...

Effect of grain moisture content and storage time on efficacy of inert and botanical dusts for the control of Sitophilus zeamais in stored maize

The effect of grain moisture content and time of storage on the efficacy of inert and botanical dusts, conventional and bacterial metabolite insecticides were evaluated in the laboratory. Maize grains at 10, 12, 14 and 16% moisture content were admixed with inert powder (diatomaceous earth Kensil Superfine®), maize cob and bean trash ashes, and botanical (neem seed cake powder) at a dose rate of 0.9% w/w. Actellic...
