highest density is honey‚ while alcohol stands in the place of the lowest. The density of the fluids determines where each layer should be arranged in the glass container. Honey had a high density of 1.52g/mL‚ and with the high density comes high viscosity‚ which is why honey was poured first‚ becoming the bottom layer. The particles in the fluid were closely-packed due to the high density‚ and due to its thickness‚ which caused the honey to weigh greater compared to the other fluids in the glass container

conductivity and thermal diffusivity. When considering the heating or cooling of foods‚ some other physical properties must be considered because of their intrinsic relationship with the ‘‘pure’’ thermal properties mentioned‚ such as density and viscosity. Therefore‚ a group of thermal and related properties‚ known as thermophysical properties‚ provide a powerful tool for design and prediction of heat transfer operation during handling‚ processing‚ canning‚ and distribution of foods (Fig. 4.1).

molecular mass is 266.3 grams and its IUPAC name is (RS)-4-(2-hydroxy-3-isopropylaminopropoxy) phenylacetamide. Its melting point 152-155 degrees Celsius‚ has a dissociation constant (pKa) of 9.6 at 24 degrees Celsius. It is soluble in water‚ ethanol and methanol but it is insoluble in ether 2.Atenolol can be synthesized in two parts. The first synthesis is with the reaction of phenol and formaldehyde to form the 4-(hydroxymethyl)phenol the second is treating the 4-(hydroxymethyl)phenol compound with NaCN

The genus Ocimum L. (basil) is a member of the Labiatae family which is an important economic and medicinal herb (Paton‚ Harley and Harley‚ 1999). The seeds of Ocimum basilicum are high in fiber and in some regions in Asia like Iran and India‚ basil seeds are frequently included in beverages (Sharbat) and ice desserts (Faloodeh) for aesthetic purposes as well as a source of dietary fibre (Hosseini-Parvar‚ Matia-Merino‚ Goh‚ Razavi et al.‚ 2010‚ Mäkinen and Pääkkönen‚ 1999).
