In this insightful study, Kemin researchers explore how the quality of frying oil impacts the oxidative stability and shelf life of deep-fried tortilla chips. The findings reveal that chips fried in abused oil degrade rapidly, becoming rancid and losing sensory appeal within weeks. However, when the oil is treated with FORTIUM RG20 Liquid, a natural flavouring, the chips maintain freshness and flavour twice as long.
