Edible oils like palm oil, safflower oil, and olive oil have a distinctive colour based on their ingredients and production techniques. Colour measurement with a spectrophotometer can improve the production of edible oils, resulting in consistent quality and high sales.
Monitoring the colour changes throughout the production of edible oils is crucial. At the start of production, spectrophotometers can monitor pigmentation levels in crude seeds. This data can predict if the edible oil product will have a higher pigmentation level than normal due to the seed's growing conditions.
Continuous colour measurement can help determine necessary changes to make throughout processing to ensure the desired colour outcome. The various chemical and physical refining processes — such as bleaching and filtering — give edible oil its desired colour. These processes can be adjusted as needed based on an oil's intended use.
Measuring turbidity simultaneously with colour can identify any sample crystallization and thermal currents within the sample. Crystallization and thermal currents occur due to improper sample temperature, which can cause inaccurate colour measurement results as well as repeatability problems. Turbidity measurements can also identify any particulates and physical contaminants that may be present due to improper filtering.
Colour measurement solutions like spectrophotometers provide automatic, accurate, and repeatable data. Edible oil manufacturers can use this data to improve the quality of the product. Colour and turbidity measurements can indicate when further bleaching, blending, or filtering processes are required to give the edible oil the correct colour and appearance. This information helps manufacturers avoid making uninformed decisions that would alter the product. The HunterLab Vista is the only spectrophotometer in the industry that measures colour and haze simultaneously.
Measuring the colour and turbidity of edible oil is essential for quality control. Slight colour and haze variations can make a customer believe something is wrong with their product, even if the oil is fresh and clean. Colour and turbidity measurements help with quality control by providing the data needed to optimize production processes like deodorizing, bleaching, and filtering. Reliable quality control methodologies lead to consistent colour and appearance results and product output, which helps build consumer loyalty.
Continuously monitoring colour throughout production saves valuable time. Having to apply additional bleaching and blending methods can be time-consuming, slowing your operation's output. Colour data from a reliable spectrophotometer can prove when these processes are not needed, saving production time and getting your edible oil to market faster.
Colour interpretations vary from one person to another due to physical capability, age, gender, and even psychological factors like fatigue, beliefs, and desires. These factors make visual perception subjective. Spectrophotometers remove subjectivity by providing quantifiable data to express a product's colour. Data is more reliable than the human eye and reduces colour communication problems.
Colour measurements help edible oil manufacturers meet compliance standards. For example, the United States Department of Agriculture requires strict colour measurement data if a company wishes to make health claims about a product.
