Vacuum frying, on the other hand, operates at relatively lower temperatures (e.g.,
130oC). Apart from high quality retention in the final product obtained by vacuum frying,
the main difference of the two techniques is the investment cost and operational cost. For
deep frying home appliances can be used, however, in order to do commercial production
on mass scale, additional care must be given for keeping the process hygienic and the
materials used should conform to the principles of Good Manufacturing Practices (GMPs).
