Abstract:
This paper presents an ultrasonic method to measure the physico-chemical properties of mustard oil. This oil has a distinctive pungent taste, characteristic of all plants in the mustard (Brassicaceae) family.1 Over last decade less work has been done in evaluation of physico-chemical for a wide variety of mustard oil using ultrasonic technique. Ultrasound can be used to determine the dynamic rheology and composition of oils, the oil contents.2 Mustard oil has been ultrasonically assessed because of it has an important implication in spread ability and consistency of fatty materials. Ultrasonic velocity and attenuation measurements have useful in investigations of structures of oils and interactions between the molecules.3 The ultrasonic velocity (v), density (ñ), acoustic impedance (Z), adiabatic compressibility ( ), free length ( ) have been measured at fixed frequencies, 3MHz, in mustard oils. Mustard oils have characterized for specific gravity, ash content, iodine value, acid value, saponification value, peroxide value, free fatty acid, and refractive indices using standard methods.4 Low power ultrasound [LPU] in the food industry is as an analytical technique for providing information about the physicochemical properties of foods, such as composition, structure and physical state are responsible for changes in acoustical parameters.5,6 Physical properties of edible oils depend primarily on composition and temperature. The influences of temperature on physical-chemical properties are analyzed so that the refined oils and other exotic varieties have arrived recently. Mustard oil is best when consumed in its raw form known as ‘kachchi ghani’. “Our forebears have used mustard oil for centuries”. A comparative study of different brands of mustard oil has shown in present paper.
