Vacuum frying has many advantages over normal deep fat frying such as less oil uptake, less frying time, less shrinkage, can preserve natural color and flavor, and has less adverse effects on oil quality. Several studies suggest that the presence of the carcinogen acrylamide, a chemical compound, is reduced by the vacuum frying method. Regular, atmospheric deep-frying methods apparently do not...

Weekly commentary on vacuum frying technology—Vacuum Fryer

Post Time: 2021-05-06

  There are two types of vacuum fryers. Intermittent fryers are used for smaller operations and are suitable for vegetables and fruit. Larger, continuous fryers are better for more sustained commercial use. The intermittent vacuum fryer's oil has to be replaced more often than the continuous fryer. This makes the continuous vacuum fryer more attractive to larger manufacturers as it lowers the cost of production. The vacuum fryer is relatively simple to operate. Pumps create the vacuum and programmable electronics allow the user to control the system. Research has shown that... Read More
