modified VERI-FRY quick test for measuring total polar compounds in deep-frying oils

The AOCS official method for the determination of total polar compounds in deep‐frying oils is often used to estimate frying oil degradation. It can be accurate and reliable, but with sacrifices of time and expense. The TPM VERI‐FRY® PRO (Libra Technologies, Inc., Metuchen, NJ) quick test provides a...

Description
Summary:The AOCS official method for the determination of total polar compounds in deep‐frying oils is often used to estimate frying oil degradation. It can be accurate and reliable, but with sacrifices of time and expense. The TPM VERI‐FRY® PRO (Libra Technologies, Inc., Metuchen, NJ) quick test provides a quick and easy way to measure polar compounds in frying oils. The modified quick test measured at 490 nm has a good correlation with the AOCS official method (r=0.975, P
