The oil must be protected from light to prevent oxidation, which produces a substance harmful to the liver and irritating to the gastric mucous membranes (Acrolein). If you’re not frying, but your shift isn’t over yet, lower the oil temperature to 120°C.
All Veneto Macchine fryers have cover and temperature management devices. Semi-automatic and automatic fryers work with the tank covers applied to avoid exposing the oil to direct light. With the covers applied, the extraction of fumes can be automatically managed to improve the propagation of odors and vapors.
