Manufactured by VeriVide Ltd The DigiEye System a complete non-contact color measurement and imaging solution.

The challenge faced by sweet manufacturers Colour Management Of Sweets The challenge faced by sweet manufacturers Sweets tend to have irregular or curved surface Can have either glossy or matte appearance They have varying degrees of opacity They can be very small and difficult to measure Not always a solid colour, may be multiple colours Use of natural colourants – Stability issues

The traditional method of Quality Control has been either: Colour Management Of Sweets The traditional method of Quality Control has been either: Visual Assessment with uncontrolled or inconsistent viewing methods in terms of : The Observer - subjectivity Light Source Angle of Observation OR Instrumental Measurement (Spectrophotometer / Colorimeter) with restrictions and limitation. . . . Works well on flat, opaque objects – Very limited on curved or irregular surfaces. Limited by aperture size, averaging the colour of the selected area. Cannot differentiate between different colours in the selected area. The xenon flash can be too powerful for translucent sweets. It will illuminate the sweet internally, influencing the colour measurement The product can be distorted by the aperture

DigiEye – Measuring Colour in Context Colour Management Of Sweets The Solution: DigiEye – Measuring Colour in Context The DigiEye System from VeriVide is different. Digitally capturing and measuring ….. Texture, Colour & Appearance High Resolution - Great Precision. Consistent and Repeatable results. Calibrated images – Colour visualisation. Measures colour in context not in isolation. Colour as seen by the consumer.

What is DigiEye? DigiEye is a digital colour imaging system with many proven applications in the food & confectionary sector. Offers the ability to consistently and reliably measure colour & appearance using a non-contact method. Characterized SLR Camera. Recording colour data at millions of points Calibrated Monitor & Printer. Accurate on-screen product representation. Colour accurate photographic images. Enclosed ‘DigiEye Cube. Eliminating all ambient light. Product capture in Consistent lighting Both Angled and Diffuse lighting.

Measuring Sweets Using DigiEye DigiEye does not have the aperture restrictions of a spectrophotometer We can measure the whole imaged area Allowing either accurate average colour Very flexible selection of individual colours within the image Software compensation for uneven surfaces Non-contact – Does not distort the product Measures the surface colour – as seen by the consumer Visualise AND measure the colour differences Shelf life/colour stability trials

Measuring Sweets Using DigiEye Having an image allows you to be very selective of what you measure Using sophisticated selection tools we can measure accurate non-solid colour We can compare colour difference between standard and batch or batch to batch Much more representative of how the consumer will view the colour

Colour Comparison Using DigiEye – An Example Translucent products are very difficult to assess instrumentally The background influences the colour Using DigiEye we can select the whole object Software correction limits the effect of the background This allows us to give sensible colour difference values unlike traditional instrumental assessment

Colour Comparison Using DigiEye – An Example DigiEye software correction offers benefits for opaque samples too Note that the sample in the top right has a texture difference This can influences the colour We select the standard or recall it from a database DigiEye then compensates for the structure and return accurate difference information

Measuring Surface Distribution Characteristics Using DigiEye DigiEye can be used to assess the percentage distribution the ‘sour sugar’ coating This information can be used to detect any deficiencies in the coating process We can visualise using ‘false colour’ the coverage of the sugar crystals We can see both visually and numerically that the sample on left has insufficient coating

Measuring Surface Distribution Characteristics Using DigiEye DigiEye can also be used to assess other surface characteristics Here we are assessing the area that the jelly ‘yolk’ has bled in to the ‘egg white’ Again this information could tell us about production deficiencies It was found that the coverage of the jelly ‘yolk’ was very consistent The bleed however varied by almost 15% between maximum and minimum coverage
