Paper Title: Food Analysis and Quality Control Module-10: Refractometry Food Analysis 10.1 Introduction Refractometry is a method of testing the physicochemical properties of a substance (commonly liquids) bymeasuring its refractive index. Refractive index of a substance is the ratio of speed of light
refractive index identification
Refractometers are essential scientific instruments used to measure the refractive index of substances. These devices have revolutionized various industries by providing accurate measurements of liquid concentrations and purity levels. Refractometers measure how light bends as it passes through a sample, allowing for precise determination of .Since the (absolute) refractive index of the medium of interest as well as the refractive index of air depend on temperature, it is necessary to specify the details. Common variants are: the temperature-dependent refractive index of the medium relative to standard air, that is air at 20 °C, 1013 hPa, and 50 % relative humidityThe MyBrix measures refractive index and sugar content instantly and precisely: Results are received within just 2 seconds in the desired scale. Fits in any pocket The MyBrix pocket refractometer is compact, lightweight, and designed to fit comfortably in the hand.Measurement of the refractive index of the test solution at 20 0C, using a refractometer, and use of tables correlating refractive index with soluble solids content (expressed as Sucrose), or direct reading of the soluble solids content on the refractometer. 1.6.2 Apparatus
Refractometers pass light through a food or beverage sample and measure the angle of refraction. Once the light passes through the reader, it measures the refraction — the angle that the light bends — and gives you the .
Density and refractive index are routinely measured for quality control in the food and beverage industry, often to determine the Brix value of raw material and finished products. Although the designation “°Brix” is strictly valid only for pure sucrose-water solutions, in practice, the term as well as the methods of measurement are often .The refractive index is calculated from this critical angle. In addition, benchtop digital refractometers / brix meters use a built-in Peltier thermostat to control the temperature of a sample. Learn more about the definition of refractive index, applications, how to measure it, Snell's Law and much more.
4. Snell's law • describe the relationship between the angles of incidence and refraction, • Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media, labelled n1, n2 and so on, are used to represent the factor by which a light ray's speed decreases when travelling .
The HI96803 portable refractometer converts the refractive index of a food sample to % glucose by weight. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in refractive index with temperature for a percent by weight glucose solution.Sugar, through °Brix and °HFCS units, is mostly measured with refractive index or density in the beverage and food industry.

The HI96821 is an easy to use tool for measuring sodium chloride in foods, whether on the production line or in the lab.
The refractive index of water at 20°C is 1.330; if solute is added to the water, the refractive index of a dilute solution increases linearly and proportionally to the solute concentration; at higher concentrations of dissolved solids (50–200 g l −1), the increase is nearly linear. Temperature affects appreciably the refractive index of a . Because of this advantage, refractive index refractometer is used as a convenient method for measuring Brix of turbid colloidal fluids, such as fruit and vegetable juices (Dongare et al., 2014). The Brix refractometer has advantages over other methods of estimating SSC concentration in that it is inexpensive, readily available, less fragile .
