Description
Summary:In the harvesting season, its commercial price goes down very fast because it is very easy to be decomposed. [...]damage of fruits by insect pests is one of the major problems faced by fruit sellers (Ugwu, J.A.; Umeh, Vincent., 2015). Fruits were washed thoroughly under turbulent washing to remove dirt, dust and adhered unwanted material. Besides star apple fruits we also used other materials during the research such as sugar, Petrifilm-3M. Samples were analysed for brix, titratable acidity (g citric acid/100 g), pH, aerobic mesophilic bacteria and moulds/yeasts counts and coliform counts at regular intervals of one week. 2.3 Physico-chemical and biological analysis Star apple juice was filtered on a cotton cloth and the volume (yield) of juice obtained from each sample was measured using a 500 ml volumetric flask. The viscosity, shear stress and shear rate of African star apple juice (Chrysophyllum albidium) at different concentrations of 8 % to 32% total solid concentration and temperature range of 20°C to 70°C were obtained in order to determine the effect of changes in concentration and temperature on the rheological properties of the juice.
