3 Near Infrared (NIR) Technology Built On MCT-360 Platform Near Infrared (NIR) region ( nm). The NIR is above the UV (sunburn) and Visible (What you see) colors of light, and below the IR (temperature) region of light. Selected narrow band pass filters that allow specific wavelengths to be utilized for the measurement. Moisture absorbs light at 1420 and 1940 nm and one or both of these wavelengths are used as the measure wavelength. Hydrocarbons (oil/fat) absorb light at 1720 and 2340 nm and one or both of these wavelengths are used as the measure wavelength. One or two non-absorbing wavelengths are chosen as reference wavelenths. An algorithm (math equation) compares the values and provides an accurate and linear measurement of moisture or fat/oil.

4 What Is Color & How Do We Measure It? Color Measurements try to replicate what the human eye will see Eliminate the variation between individual perceptions with a standard comparative scale Three main color scales are employed in the industries we serve: CIE L*a*b* Hunter L,a,b Agtron The most important determining factor in scale selection is consistency in using the same scale, and historic data in a specific color scale. CIE L*a*b* and Hunter L,a,b are both based on the established CIE L*a*b* scale. This scale uses three parameters to represent human eye color perception and plots it into a tristimulus three dimensional format. The L* axis representing Light to Dark values The a* axis representing Red to Green values The b* axis representing Yellow to Blue values

5 What Is Color & How Do We Measure It? The CIE L*a*b* tries to correct or match the non-linearity present in the human eye by using the cube root of the XYZ scale The Hunter L,a,b makes it calculations based on the square root values of the XYZ scale. Both scales work as long as they are used consistently. Allegedly the Hunter has greater color discrimination in the yellow zone on low values and the CIE has greater color discrimination on darker colors. The Agtron scale is based on red-yellow-green-blue (RYGB) reflectance to provide a numeric score for each of these color bands in the visible spectrum. There are several other color scales too. The MCT-MultiPlex Color Meter is a white light source Color Meter with flexible software to meet your color measurement needs.

13 Maillard Reaction The Maillard reaction describes a non-enzymatic chemical reaction between amino acids (proteins) and reducing sugars that accelerates with heat and produces a browning effect on many processed foods including fried and baked products The Maillard reaction describes the impact on odor, flavor, and appearance due to the browning reaction The a* value (Red to Green) offers a valuable tool in monitoring the browness indicative of the Maillard reaction
