NEW AND INNOVATIVE! Instant, hassle-free method of measuring oil degradation by Atago®.

Now you don’t have to guess how old the frying oil you’re using is; or if it is safe to eat. The uncontrolled, continuous use of old frying oil can result in dirty, smelly and unsafe food.

When oil is used over and over again to fry food, they break down and form polymerized triglycerides (PTGs / varnish like compounds). These compounds can cause diarrhoea, atherosclerosis and cancer.

Edible Oil is strictly regulated by governments. The legal limit of PTGs in South Africa is < 16%. Oil that has higher PTGs is legally unsafe for use and needs to be replaced.

The cooking / edible oil industry in South Africa has also adopted the Steward’s Principle, a programme that requires all those in the product life cycle to share responsibility for reducing the environmental impact of products. Each manufacturer, distributor and frying establishment is required to be responsible for the quality of frying oils. Find out More

The new Atago® DOM-24 is as easy to use as a thermometer. Anyone can obtain reliable, precise digital measurements. No special expertise is required. No special reagents or chemicals are required. A great, low cost alternative to long and involved titration tests.
