Vacuum frying machine utilizes three different stages for processing:
Vacuum Fried Chips
Vacuum Deep Fried Chips
vacuum frying qualities:
Atmospheric Frying | Vacuum Frying |
---|---|
Oil Uptake in vacuum-fried chips is higher | Oil Uptake in vacuum-fried chips is Lower |
Colour of vacuum-fried products darker | Colour of vacuum-fried products was lighter |
Carotenoid retention of was lower | Carotenoid retention of was higher |
Oil Uptake in vacuum-fried chips is higher. Atmospheric fried food was soggy, burnt and oily | Oil Uptake in vacuum-fried chips is Lower. Vacuum fried products was more uniform and crispier |
Oil degradation is much lesser | Oil degradation is higher |
High acrylamide content | Low acrylamide content |
Atmospheric fried products have high moisture content (˃0.3) and high water activity (aw˃0.3) | Oil Uptake in vacuum-fried chips is Lower. Atmospheric fried products have high moisture content (˂0.3) and high water activity (aw˂0.3) |
Oil stability is Lower after frying | Oil Uptake in vacuum-fried chips is Lower. Oil stability is higher after frying |
