Measuring the Colour
of Vegetable Oil
Acceptability of colour has been the top priority in vegetable oil manufacturing due to the well-known correlation between colour perception and product quality. HunterLab provides the ideal colour measurement solutions to ensure that the finished product is flawless and meets the specific standards that the edible oil industry demands. Our innovative colour measuring instruments give producers quantitative values to accurately evaluate their quality.
Why use spectrophotometers to measure the colour of vegetable oil?
Many in the industry are still using outdated visual comparison methods of colour measurement. Spectrophotometers provide far greater accuracy, far greater consistency and are able to provide reliable inter-instrument agreements from anywhere on the globe.
Why measure the colour of vegetable oil?
Vegetable oils such as olive oil, soybean oil, canola oil and peanut oil must meet consumers' visual expectations with consistent coloring.
Colour and appearance measurements play a crucial part in the refining process of vegetable oil. This data helps to identify the optimum level of refinement and grading of vegetable oil before distribution. HunterLab spectrophotometers and QC solutions provide accurate and consistent colour and appearance data that can improve the efficiency and consistency of your grading process.
Since vegetable oils are made from fruits, seeds, and nuts, they have wide variations in colour. Besides the ingredients, other factors influence the colour consistency of vegetable oil. When improperly stored, vegetable oil is exposed to light, heat, and oxygen. Oxidation in vegetable oil causes its carotenoids and chlorophyll to dissipate, resulting in a colour change. This exposure can also affect the oil's scent and taste.
Spectrophotometers can be used to measure vegetable oil colour and haze (turbidity) throughout the entire production process to improve and maintain colour and appearance consistency. As a result, vegetable oil manufacturers can meet food quality standards from the FDA and customers' expectations. HunterLab spectrophotometer can simultaneously measure colour and haze (turbidity). As a result, you only have to buy one tool for both measurements, and you only have to test your samples once to get both values.
HunterLab’s transmittance spectrophotometer offers a faster and more modern method for colour measurement using the LOVIBOND® RYBN and AOCS colour scales. Since consumers select products by colour, HunterLab helps vegetable oil manufacturers meet consumer expectations and regulatory requirements. It also comes with the new and improved colour software, Essentials 2.0. Take precise and reliable colour measurements in seconds with next-gen user-friendliness and seamlessly analyze multiple tristimulus and spectral data sets. It’s that powerful.
Rather than requiring expensive and hard-to-clean 1-in or 5.25-in transmittance cells, it enables small quantity sample measurements (as small as 10mm) in inexpensive transmittance cells and vials. With only 5 seconds per measurement, our unparalleled colour measurement solution improves productivity and requires less sample material and less time on post-measurement cleaning.
HunterLab makes your quality assurance process simple with an easy-to-use modern interface, the latest data communication features, and all the pre-equipped colour scales and indexes you need including Gardner, Hunter L,a,b, CIELAB, LOVIBOND® and AOCS RY. In short, HunterLab ensures the best value by offering the lowest total cost of ownership, lowest maintenance costs, lowest service costs, our renowned long instrument lifespan, and our stellar customer service.
